The Unicook B600701 is a 55 inch universal grill cover in black. It drapes over a cart grill from lid to wheels. Amazon listed it at $26.59 on 2026-10-19.
Unicook’s fitted Weber Q bonnet, the B63-015, names its grill. A drawstring is its only hardware. This universal names no grill at all. Instead it brings handles, two vents and a pair of straps.
So here is the trade. A universal has to buy with hardware what a fitted cover gets from its shape. Does this one buy enough?

First Impressions of the Unicook B600701
Unfolded, the B600701 is a tall black polyester tent. It weighs 3.6 pounds by Unicook’s figure. The inside face is a smooth vinyl backing, and the outside is a tight weave.
Unicook’s gallery points out three things on the cloth. Two loop handles sit on the top edge. A flap on each side hides a mesh vent. Low on each side, a hook and loop strap waits to wrap a leg.
Drop it on a three burner cart and the shape is plain. It reads as a rectangle with rounded shoulders. On a grill near 53 inches wide it sits close. On a narrower grill the sides hang loose until you pull the straps.
There is nothing to assemble. Lift it by the handles, walk it over the lid and let it fall.
Key Features of the Unicook B600701
Most of what separates this cover from Unicook’s own fitted bonnet is hardware. Here is what the listing documents.
- Vinyl-backed polyester. Unicook pairs a waterproof backing with an anti UV, water repellent outer coat.
- Solution-dyed fabric. The maker calls it fade resistant and pictures it beside a washed out rival.
- A thickness claim in pictures. A gallery dial gauge reads 0.45mm on this cloth. An unnamed rival reads 0.08mm.
- Two concealed mesh vents. Unicook says they move air and also steady the cover in wind.
- Top handles. They lift the cover on and off and double as a hanging loop.
- Side straps. Hook and loop fastening at two sides holds the lower edge.
- BBQ Cover. It is a universal cart cover, sold by size rather than by grill model.
Fit and coverage
Unicook sells this size for 3 to 4 burner grills from 47 to 53 inches wide. It lists brands such as Weber Spirit and Genesis, Char-Broil, Nexgrill and Napoleon. It never lists a model, and it asks you to measure first. Its fitted Q bonnet, by contrast, names the one Weber it will not fit.
That range carries a quiet problem. On a 53 inch grill, the 55 inch cover leaves 2 inches spare. That matches Unicook’s own advice to go 1 to 2 inches larger. On a 47 inch grill the spare is 8 inches.
The gallery headline drops the lower bound and just says up to 53. So the straps do real work here. They cinch loose sides against the frame and stop the flapping. But they cannot make 8 inches of extra width look tailored.
Height is the other number to check. At 42 inches, it is built to reach far down a cart. Depth runs 23 inches, so a deep side shelf deserves a second look with the tape.
Weather protection and durability
The weather case stacks three layers of claim. A water repellent coat sits on the face. A vinyl backing sits behind it. And two mesh vents let damp air out under the side flaps.
That last part is the gain over the fitted Q bonnet. A backed cover traps the moisture a cold grill gives off overnight. Vents give it a way out. Unicook also says the vents even out air pressure, so wind has less to grab.
Fade and cold claims are bolder than the evidence. Unicook says the cloth is solution dyed and will not crack in winter. No test method is named for either. Treat them as the maker’s promise, not a result.
Durability rests on that gauge photo. The reading of 0.45mm against 0.08mm is Unicook’s own picture of an unnamed rival. The headline calls it 4x thicker, while those two readings work out to more than five. No denier is published, the stitching is not described, and no warranty term appears.
Handling, upkeep and value
Here the universal pulls ahead of its fitted sibling. The handles change the job. Hook two fingers through the top loops and swing it over the lid. Off the grill, the same loops hang it on a hook.
Care is simple. A hose rinse and a day in the sun clean it. The FAQ adds a warning worth keeping: no machine washing, or the waterproof coating suffers. And let the grill cool fully first, since trapped heat can damage the cloth.
On value, $26.59 buys more hardware than Unicook’s $19.99 Q bonnet carries. That bonnet has a drawstring and nothing else. Against other universals of this size, the price sits in the ordinary band. The vents and handles are what tip it toward good.
Possible Unicook B600701 Complaints
- Loose sides on a narrow grill. Below about 50 inches wide, there is cloth to spare. The straps pin the lower edge, but the upper sides can still billow. On a grill that narrow, the 50 inch size may sit closer.
- No warranty in writing. Unicook says it stands behind its products but prints no term. If a strap tears loose, you are relying on goodwill rather than a policy.
