A pellet grill does a lot on its own. It lights itself, feeds its own fuel and holds a set temperature, which is why it suits long cooks like pork shoulder for tacos or beef cheeks done in the style of barbacoa. But the grill only knows the temperature of the air inside it. It does not know when the meat is done, it does not keep its pellets dry, and it does not clean its own grease bucket.
That is where accessories earn their place. This guide covers the handful that solve real problems: thermometers that tell you what is happening inside the meat, storage that keeps pellets dry, a cover, grill mats, drip liners and a front shelf for prep space. For each we list what the maker or the Amazon listing states, and we write “Not stated” where neither gives a figure.

Quick verdict: which pellet grill accessories to buy first
If you buy one accessory, make it a good probe thermometer. The ThermoWorks Signals watches up to four channels at once, meat and pit, and alerts your phone over Wi-Fi or Bluetooth. If you want no wires at all, the MEATER Pro is a fully wireless probe. After that, keep your pellets dry with the Traeger StayDry Pellet Bin, keep the grill dry with a fitted cover such as Traeger’s Full-Length Cover for the Pro 575, and make cleanup easier with Grillaholics Heavy grill mats.
The table below shows those five side by side. All eight accessories are reviewed in full after it.

Our picks for the best pellet grill accessories
These eight cover the jobs a pellet grill cannot do for itself: reading the meat, protecting pellets and the grill from water, catching grease and giving you somewhere to work. Fit matters for the cover, liners and shelf, so check your grill’s model number before you order those.
1. ThermoWorks Signals 4-Channel Thermometer – Meat and Pit on One Screen
A pellet grill’s controller reads the air near one probe inside the barrel, and that is all. Signals adds what the grill cannot: the temperature inside the meat, and a second opinion on the pit. The listing says it tracks up to four channels, meat, pit or both, on one display, and it includes Pro-Series High Temp cooking probes and an air probe for the pit.
For a long cook such as a pork shoulder for carnitas-style tacos or a brisket, the alarms are the point. You can set high and low alarms for each probe and get alerts on your phone over Wi-Fi or Bluetooth, or use it as a standalone alarm thermometer without the app. ThermoWorks lists an IP66 splash-resistant housing, magnets and a stable base, and a rechargeable battery good for up to 16 hours of wireless use, with an adapter for continuous power on longer cooks.
The listing does not give the probes’ heat rating, the unit’s size or the warranty, so we mark those “Not stated”. Probes are wired, so the cables run under the lid; that is normal for this kind of thermometer.
Why we like it
- Four channels: up to four meats, or meat plus pit
- Wi-Fi and Bluetooth alerts, or standalone use
- IP66 splash-resistant housing with magnets
- Up to 16 hours of wireless battery use
Key specifications
| Model | AZ-1505-CY |
|---|---|
| Type | 4-channel alarm thermometer, Wi-Fi and Bluetooth |
| Fits | Any grill or smoker |
| Material | IP66 splash-resistant housing |
| Size | Not stated |
| Heat rating (stated) | Not stated on listing |
| Dishwasher safe | Not stated |
| Warranty | Not stated on listing |
Why we recommend it
It suits anyone who smokes big cuts and wants to know both the meat and the true pit temperature without standing by the grill.
Skip it if you only grill quick steaks and chicken thighs; an instant-read thermometer is simpler for that.
Pros and cons
Pros
- Four probes in one unit
- Phone alerts with high and low alarms
- Works without the app
Cons
- Wired probes to manage
- Probe heat rating and warranty not on listing
2. MEATER Pro Wireless Probe – No Cables Under the Lid
The MEATER Pro is a single probe with no wires: you push it into the meat and close the lid, and it reports to the MEATER app on your phone over Bluetooth. That makes it simple on a pellet grill, where a cable can be pinched by the lid or catch on a rack. The listing describes it as for grilling, smoking, roasting, deep frying, sous vide and more.
MEATER’s US store lists a maximum internal temperature of 221°F and a maximum ambient temperature of 1000°F; in other words, the tip in the meat must stay below boiling while the handle end can sit in a hot grill. The listing calls it dishwasher safe and fast-charging. For a pellet grill running at smoking temperatures, those limits are comfortable.
The trade-off is channels. One probe watches one piece of meat and the air around it; for two briskets or a brisket and the pit, you would need more probes or a multi-channel unit like the Signals. Warranty terms were not stated on the pages we read.
Why we like it
- Completely wire-free
- Rated to 1000°F ambient (MEATER)
- Dishwasher safe
- Custom alerts in the MEATER app
Key specifications
| Model | OSC-MT-MP201 |
|---|---|
| Type | Wireless smart meat probe, Bluetooth |
| Fits | Any grill, smoker or oven |
| Material | Not stated |
| Size | 5 mm probe diameter (MEATER) |
| Heat rating (stated) | 221°F internal, 1000°F ambient |
| Dishwasher safe | Yes |
| Warranty | Not stated |
Why we recommend it
It suits cooks who smoke one roast, chicken or brisket at a time and want nothing trailing out of the lid.
Skip it if you cook several cuts at once or want to monitor the pit itself; one probe cannot do both jobs for several pieces.
Pros and cons
Pros
- No cables to pinch
- High ambient rating
- Easy cleanup
Cons
- One piece of meat per probe
- Relies on a phone app
- Warranty not stated
3. Traeger StayDry Pellet Bin, 22 lb – Airtight Pellet Storage
Damp pellets are the most common pellet-grill problem, and Traeger says so plainly: poor pellet quality, often from poor storage, is the number one cause of temperature issues, and moisture makes pellets swell and crumble until they clog the auger or fail to light. In a humid place like Houston, an open bag on the patio does not last.
The StayDry bin is Traeger’s answer. The listing describes an airtight lid with a locking closure, a 22-pound capacity that holds a full 20-pound bag, a stackable shape for keeping several flavors, and six pre-labeled and six blank flavor stickers. Traeger’s storage page adds that it fits under the hopper on newer models. Traeger notes on the listing that it is not for food storage.
Any brand of pellet fits, not just Traeger’s. The listing does not state the material or dimensions.
Why we like it
- Airtight lid with a locking closure
- Holds a full 20 lb bag
- Stackable for several flavors
- Flavor stickers included
Key specifications
| Model | BAC637 |
|---|---|
| Type | Airtight pellet storage bin |
| Fits | Any pellets; under the hopper on newer Traeger models |
| Material | Not stated |
| Size | 22 lb capacity |
| Heat rating (stated) | Not applicable |
| Dishwasher safe | Not stated |
| Warranty | Not stated |
Why we recommend it
It suits anyone who keeps pellets outdoors or in a garage, especially in a humid climate, and anyone who keeps more than one flavor.
Skip it if you buy 40-pound bags; one bin holds about half.
Pros and cons
Pros
- Locking airtight lid
- Stacks neatly
- Works with any pellet brand
Cons
- Too small for a 40 lb bag
- Material not stated
4. Oklahoma Joe’s Pellet Bucket Kit – Sifts Out the Dust
Oklahoma Joe’s kit is a storage bucket with a twist: a wire-mesh filter inside that separates wood dust from the pellets, a heavy-duty plastic scoop and an airtight lid. The listing calls the design weatherproof, to keep hardwood pellets fresh and dry.
The filter is the useful part. Traeger says a little sawdust at the bottom of a bag is normal, but a lot of it, or sawdust that clumps, is a sign the pellets have been compromised. A filter bucket keeps loose dust back as you scoop, so less of it goes into the hopper.
The listing does not give the bucket’s capacity, material or dimensions, which is an odd gap; if you buy 40-pound bags, plan on more than one container. It works with any pellet brand.
Why we like it
- Wire-mesh filter separates dust from pellets
- Airtight lid
- Scoop included
- Weatherproof design (listing)
Key specifications
| Model | 5159038W01 |
|---|---|
| Type | Pellet bucket with filter, scoop and lid |
| Fits | Any pellets |
| Material | Plastic scoop, wire-mesh filter; bucket not stated |
| Size | Not stated |
| Heat rating (stated) | Not applicable |
| Dishwasher safe | Not stated |
| Warranty | Not stated |
Why we recommend it
It suits cooks who want cleaner pellets going into the hopper and like scooping rather than tipping a heavy bag.
Skip it if you want to know exactly how much it holds; the listing does not say.
Pros and cons
Pros
- Built-in dust filter
- Complete kit with scoop
- Airtight lid
Cons
- Capacity not stated
- Bucket material not stated
5. Traeger Full-Length Grill Cover, Pro 575 – A Fitted Rain Cover
A pellet grill has electronics, an auger and a hopper full of wood, and water is bad for all three. A fitted cover is the cheapest protection you can buy for it. Traeger’s BAC503 is made for the Pro 22 and Pro 575, and the listing describes a heavy-duty, all-weather material that is water resistant, in a form-fitted design that is easy to put on and take off.
A cover made for your model matters on a pellet grill because of the hopper and chimney: a loose universal cover can leave the hopper lid exposed or pool water on top. Traeger sells covers for its other models too, and we found fitted covers for Pit Boss and Camp Chef grills, mostly from third-party makers, so search for your exact model number.
Traeger does not state a heat rating for the cover, so let the grill cool completely before you put it on. Material and warranty are not stated on the listing.
Why we like it
- Made for the Pro 22 and Pro 575
- Heavy-duty, all-weather material
- Water resistant
- Form-fitted, easy on and off
Key specifications
| Model | BAC503 |
|---|---|
| Type | Full-length fitted grill cover |
| Fits | Traeger Pro 22 and Pro 575 |
| Material | Heavy-duty all-weather material; fabric not stated |
| Size | Cut for Pro 22 and Pro 575 |
| Heat rating (stated) | Not stated; cover a cool grill |
| Dishwasher safe | No |
| Warranty | Not stated |
Why we recommend it
It suits Traeger Pro 575 and Pro 22 owners whose grill lives outdoors year-round.
Skip it if you own another model; it is cut for these two grills only.
Pros and cons
Pros
- Exact fit for two popular grills
- Water resistant
- Maker’s own part
Cons
- Fits only two models
- Material and warranty not stated
6. Grillaholics Heavy Grill Mats, Set of 2 – Nothing Falls Through
Grill mats are thin, nonstick sheets you lay on the grate. On a pellet grill they are useful for food that sticks or falls through: sliced onions and peppers for fajitas, shrimp, fish fillets, or jalapeños before they go into a salsa. Grillaholics says its Heavy mats are made thicker than its standard mats, and the maker’s page lists them as PTFE-fiberglass with a nonstick surface, rated to 600°F.
That rating is the number to respect. Check your grill’s top temperature: if it can run hotter than 600°F, keep the mats for smoking and moderate grilling, and take them off before you turn the dial up to sear. The listing calls them dishwasher safe on the top rack, and Grillaholics backs them with a lifetime guarantee.
Size is not given on the listing. A mat also blocks grill marks and some smoke contact, so it is a tool for delicate food, not for everything.
Why we like it
- Rated to 600°F (Grillaholics)
- Thicker than the maker’s standard mats
- Dishwasher safe, top rack
- Lifetime guarantee
Key specifications
| Model | GR-GMH-105 |
|---|---|
| Type | Nonstick grill mats, set of 2 |
| Fits | Any grill grate |
| Material | PTFE-fiberglass |
| Size | Not stated |
| Heat rating (stated) | 600°F |
| Dishwasher safe | Yes, top rack |
| Warranty | Lifetime guarantee |
Why we recommend it
It suits cooks who grill vegetables, seafood and small pieces that would otherwise stick or slip between the bars.
Skip it if you mostly sear steak at the grill’s top temperature; the mat’s 600°F limit and lack of grill marks work against you there.
Pros and cons
Pros
- Stops small food falling through
- Easy cleanup
- Long guarantee
Cons
- 600°F limit on hot grills
- No grill marks
- Size not stated
7. Traeger Grease Bucket Liners, 5-Pack – Toss, Don’t Scrub
Every pellet grill drains fat into a small bucket hanging off the side, and cleaning that bucket is the least pleasant job in barbecue. Traeger’s BAC407 liners are disposable aluminum inserts: drop one in, and when it is full, let it cool and throw it away.
Fit is everything here. Traeger lists the liners for its 20, 22 and 34 series, the 575 and 780 series, the Ironwood 650 and 885, and the Tailgater, and says they are not compatible with the newer Ironwood, Ironwood XL, Flatrock, Timberline and Timberline XL grease and ash keg. Pit Boss sells its own grease pan liners for its smokers, so owners of other brands should look for the liner made for their grill.
Check the bucket after every long cook and change the liner before it gets close to full.
Why we like it
- Disposable aluminum, no scrubbing
- Made for most Traeger Pro and Ironwood grills
- Clear compatibility list from Traeger
- Five liners per pack
Key specifications
| Model | BAC407 |
|---|---|
| Type | Disposable grease bucket liners, 5 count |
| Fits | Traeger 20, 22, 34, 575, 780 series, Ironwood 650/885, Tailgater |
| Material | Aluminum |
| Size | Sized for Traeger’s grease bucket |
| Heat rating (stated) | Not stated |
| Dishwasher safe | No; disposable |
| Warranty | Not stated |
Why we recommend it
It suits owners of the listed Traeger grills who cook fatty cuts often and want cleanup to take seconds.
Skip it if you own a newer Ironwood, Timberline or Flatrock; Traeger says they do not fit.
Pros and cons
Pros
- Fast, clean grease disposal
- Maker’s own part
- Clear fit list
Cons
- Only five per pack
- Not for newer Traeger models
8. Traeger Folding Front Shelf, Pro 575 – Prep Space Where You Need It
Many pellet grills ship with little or no work space, and a smoker without a shelf means balancing a tray of seasoned meat on the hopper lid. Traeger’s BAC362 folding front shelf bolts across the front of the grill, giving a place for a tray, tongs, a thermometer or a drink, and folds down flat when you are done.
The listing describes heavy-duty steel, easy installation and removal, and a design compatible with grill covers when folded. It fits the Pro 22, Pro 575 and Ironwood 650, specifically model numbers starting with TFB; Traeger sells a separate BAC363 shelf for 34-series grills. For Pit Boss and Camp Chef grills, we found front shelves on Amazon mostly from third-party makers, while Pit Boss’s own shelves were not shipping right away when we checked, so check the fit carefully.
The listing does not state a weight limit or warranty.
Why we like it
- Heavy-duty steel
- Folds flat; works with a cover
- Made for Pro 22, Pro 575 and Ironwood 650
- Easy to fit and remove
Key specifications
| Model | BAC362 |
|---|---|
| Type | Folding front shelf |
| Fits | Traeger Pro 22, Pro 575, Ironwood 650 (TFB models) |
| Material | Steel |
| Size | Not stated |
| Heat rating (stated) | Not applicable |
| Dishwasher safe | No |
| Warranty | Not stated |
Why we recommend it
It suits owners of the three listed Traeger grills who want a landing spot for trays and tools right at the lid.
Skip it if your grill is a different model; it is made for these three only.
Pros and cons
Pros
- Useful prep space
- Folds away
- Steel build
Cons
- Fits three models only
- Weight limit not stated
How to choose pellet grill accessories
The right accessories depend on how you cook and where the grill lives. These five questions sort out what to buy first.
1. Do you know when the meat is done?
The grill’s display shows the air temperature near its own probe, not the meat. A probe thermometer is the single most useful addition, and for long cooks an alarm matters more than a fancy display. Multi-channel units like the Signals watch several cuts plus the pit; a wireless probe like the MEATER Pro is simpler for one roast. Whatever you use, check doneness against the USDA Food Safety and Inspection Service’s safe minimum internal temperature chart.
2. Where do you keep your pellets?
Traeger’s advice is to keep pellets “dry and airtight”, to store unopened bags indoors or in a sealed bin in humid regions, and to empty the hopper when long rain or high humidity is forecast. If your pellets live outdoors or in a garage, a sealed bin or bucket pays for itself the first time it saves a bag. A filter bucket helps keep sawdust out of the hopper.
3. Does the grill live outside?
Then buy a cover made for your exact model, and only put it on a cool grill. A fitted cover protects the controller and hopper, which a loose universal cover may not.
4. How much smoke do you want?
If your pellet grill’s smoke tastes light to you, try stronger pellets first, then a smoke tube. Tubes add a few hours of extra smoke and let you cold-smoke cheese or salt.
5. Does it fit?
Covers, drip liners and shelves are model-specific. Find your grill’s model number in the manual or on the grill’s label, and match it to the listing’s compatibility list before ordering. Thermometers, mats, bins and tubes fit any grill.
How we picked these eight add-ons
We started from the jobs a pellet grill cannot do for itself, as a working kitchen sees them: knowing when food is done, keeping fuel dry, protecting the machine, handling grease and giving the cook somewhere to work. We then looked for products from the grill makers and established accessory brands sold on Amazon in the United States, kept only those showing as in stock when we checked, and confirmed the details on each Amazon listing and, where we could, the maker’s own pages. Where neither gives a figure we wrote “Not stated”. We left out pellet smoke tubes for now: the A-Maze-N tube showed very low stock and the Pit Boss tube was not shipping right away when we checked. We also left out Pit Boss’s own front shelves, which were not shipping right away, and generic accessories from sellers we could not identify. We have not used these products for this guide, and we did not read or rely on outside reviews such as Consumer Reports, Serious Eats or Wirecutter, so everything here comes from the makers, the listings and our kitchen’s view.
Pellet grill accessory questions, answered
What is the most useful pellet grill accessory?
A probe thermometer. The grill controls the air temperature, but only a probe in the meat tells you when a brisket or pork shoulder is done.
Do I need a cover for my pellet grill?
If it lives outdoors, yes. Traeger warns that moisture swells pellets and can jam the auger, and a pellet grill’s controller and hopper are best kept dry. Use a cover made for your model and put it on only when the grill is cool.
Are grill mats safe at high heat?
Only up to the maker’s rating. Grillaholics rates its Heavy mats to 600°F; keep them off the grill when you run it hotter than that.
Is a smoke tube worth it on a pellet grill?
If you want more smoke flavor, it is the simplest add-on. Tube listings we checked state roughly 3 to 5 hours of smoke per fill. We have no tube in this guide right now, because the ones we wanted were low on stock or slow to ship when we checked.
Do Traeger accessories fit Pit Boss or Camp Chef grills?
Thermometers, mats, bins and tubes fit any grill. Covers, grease liners and shelves are model-specific, so buy the part listed for your grill’s exact model.
Our final word on pellet grill add-ons
Start with the ThermoWorks Signals or a MEATER Pro so you always know what is happening inside the meat, then add a sealed pellet bin and a fitted cover to protect your fuel and your grill. Mats, drip liners and a front shelf make cooking easier once the basics are covered.
