The Traeger BAC889 is sold on Amazon as the Flatrock Weatherproof Flat Top Griddle Cover. That one word carries the whole pitch. Read past the title, though, and Traeger’s own copy never repeats it.
The bullets say “all-weather” instead. The cover BAC889 replaced, the BAC751, named a PVC backing on Traeger’s own page. This one names heavier cloth and no backing at all.
A griddle makes the difference sharper. Under this cover sits a seasoned steel plate. Bare steel rusts when it stays wet.
So the question is simple. Did Traeger trade a water barrier for a tougher fabric? And which does a Flatrock owner need?

First Impressions of the Traeger Flatrock BAC889 Cover
The first thing you notice is how square it looks for a cloth cover. An embroidered Traeger logo runs across the top. The shape is boxy and square-shouldered. It follows the Flatrock 3 Zone rather than draping over it like a tarp.
The corners are cut square to match the griddle’s frame. In the maker’s photographs the finish is matte. It reads as cloth, not as a rain shell.
Going on, it behaves like any form-fitted cover. Hook one corner over the griddle, then walk it round.
The one detail that stands out is a zip panel. Traeger’s description says it opens to make room for P.A.L. Pop-And-Lock rail attachments, so you need not strip the rail first.
The listing calls it weatherproof. The cloth itself makes a quieter promise.
Key Features of the Traeger Flatrock BAC889 Cover
Traeger’s copy for BAC889 is short, and every item on it is about fabric or fit. Here is what it documents, and nothing more.
- 600D abrasion-resistant polyester. Heavier than the 400D used on the BAC751 it replaced.
- Zip expansion panel. Opens around rail hooks, bins and racks left in place on the P.A.L. rail.
- Form-fitted for one griddle. Retail copy says it is “only compatible with Flatrock 3 Zone Grill”.
- Embroidered logo. Stitched, not printed, so it should not flake off.
- All-weather and heat-resistant wording. Neither phrase comes with a rating or a figure.
- BBQ Cover. It is the dedicated cover for this griddle, black only, one size.
Missing from that list are the things a cover is usually judged on. There is no coating, no vent, no strap and no handle in any copy we found.
Fit and coverage
Fit is where BAC889 earns its price. Traeger names one griddle, the Flatrock 3 Zone, and says “only”. That is a cleaner claim than most fitted covers make. The smaller 2 Zone Flatrock takes its own Traeger covers, sold under other part numbers.
The listed size is 41.5 by 26.75 by 37.5 inches. The retired BAC751 was listed at 39 by 27 by 42. So the new cut is longer and noticeably shorter.
Traeger has not explained the change. If your Flatrock sits on uneven decking, check the hem reaches low enough.
The zip panel is the feature only a maker would draw. A universal cover must stretch over rail hooks or force you to unclip them. This one opens a door for them instead. For an owner who has filled the rail, that alone could justify buying from Traeger.
Weather protection and durability
Here the title and the copy part ways. “Weatherproof” appears once, in the Amazon product name. Everywhere else, the word is “all-weather”, retailers carrying Traeger’s text included.
Traeger lists rain, snow and sun as threats. It does not say the cloth stops water.
The BAC751 page did say something about water. It listed “Durable PVC backing guards your grill” alongside 400D cloth. BAC889 moves to 600D and drops that line.
Put plainly, heavier cloth resists scuffs and tearing; it is not a sealed layer. Whether BAC889 still carries a backing is something Traeger simply does not say.
No vent is listed either. On a griddle, trapped damp air under the cover can sit on the steel plate. The safe habit is to lift the cover on a dry day after rain.
Durability is easier to credit. 600D is a sturdy weight for a fitted cover. The retailer warranty is one year limited, and Traeger’s own pages give no cover term.
Handling, upkeep and value
Putting BAC889 on takes one person and no tools. It slides on from one corner.
The zip panel saves the fuss of unclipping the rail. No handles or straps are documented. In wind, the cut alone has to hold it.
Upkeep is equally plain. Let the plate cool before the cover goes back on. The maker prints no washing guidance for BAC889.
Amazon has it around $89.95 from a third-party seller. That is ten dollars under the $99.99 list, and still maker-cover money.
So the money buys certainty of fit and a rail-friendly zip. Rain staying out is never put in writing.
Possible Traeger Flatrock BAC889 Cover Complaints
- The water claim is a title, not a spec. Owners who read “weatherproof” may skip checking the plate after a storm. Nothing on the page backs the word with a backing, a coating or a rating. If your griddle stands in open weather, treat this as a dust and sun cover first.
- It runs shorter than the cover it replaced. The listed height drops from 42 to 37.5 inches. Measure your griddle before you count on full coverage.
