A heavy duty grill cover for the Char-Griller Akorn Kamado should measure roughly 31 inches in diameter and 47 inches tall — roomy enough to slip over the dome with the side shelves folded down, fitted enough to stay put in a storm. And because the Akorn is insulated steel rather than ceramic, a weatherproof cover isn't an accessory. It's rust insurance for the whole grill.
Does the Char-Griller Akorn Kamado really need a cover?
Yes — more than most kamados. Ceramic grills like the Big Green Egg and Kamado Joe shrug off rain because fired clay doesn't corrode. The Akorn is different: its body is triple-walled steel with a powder-coat finish. That coating is tough, but it chips at seams, fasteners, shelf brackets, and around the bottom vent — and once bare steel meets moisture, rust starts working underneath the surrounding paint.
A good cover also protects the parts people forget about: the felt lid gasket, the cast-iron top vent, the ash pan, and the thermometer bezel. It keeps out pollen, tree sap, bird droppings, and wind-blown grit that grinds into the finish every time you open the lid. Even if your grill lives under a porch, humidity and dust still do slow damage — a cover is cheap protection either way.
What size cover fits an Akorn Kamado?
The full-size Akorn 22 stands roughly 45–48 inches tall on its cart and measures about 26–27 inches across the body with the side shelves folded down. That means a cover sized 31 inches in diameter by 47 inches tall slides on easily without bagging at the ground or straining at the shoulders. Our Heavy Duty Dome Grill Cover for the Char-Griller Akorn Kamado is cut to exactly those dimensions, so it fits the Akorn silhouette without wrestling it on.
Will the same cover fit other kamados?
Yes, if they're in the same size class. The 31" x 47" footprint also suits the Kamado Joe Classic, Large Big Green Egg, and other large kamados with a similar body profile — which is why we also list it as a heavy duty cover for large kamado grills. The one that won't fit is the Akorn Jr. — that portable little grill needs a much smaller cover.
How do you measure your grill before buying?
- Height: floor to the very top of the upper vent, with the grill on its cart.
- Diameter: across the widest point of the body, side shelves folded down.
- Ease: add 1–2 inches of wiggle room. A cover you fight is a cover you stop using.
What actually makes a grill cover "heavy duty"?
"Heavy duty" gets printed on a lot of flimsy vinyl. When you're comparing covers, look past the label at the construction:
- Fabric weight: a dense, high-denier woven shell resists tearing and hail far better than thin sheet vinyl, which cracks and peels within a season or two of sun.
- Waterproof backing: an inner coating that sheds rain instead of slowly wetting through.
- Seams: double-stitched or taped seams. This is where cheap covers fail first — the fabric survives, the seam splits.
- UV resistance: sun destroys covers faster than rain does. UV-stabilized fabric stays flexible instead of going brittle.
- Air vents: they let condensation escape and stop the cover from ballooning (and sailing away) in gusts.
- A real fastening system: a drawcord hem or buckle straps that cinch the cover to the cart, so it stays on through a storm.
Rule of thumb: a cover fails at the seams before it fails in the fabric. Flip it inside out and look at the stitching — that tells you more than the marketing copy.
How do you stop rust and condensation under the cover?
A cover keeps weather out, but it can also trap moisture in if you cover a damp grill. A few habits make all the difference:
- Cover a cool, dry grill. Wait until the exterior is cool to the touch — heat trapped under a cover bakes the lining and creates condensation on the steel.
- Empty the ash pan. Ash holds moisture and is mildly alkaline; left damp against steel, it's a rust starter. Dump it once it's fully cold.
- Use the vents. Position the cover so its air vents aren't pressed flat against the body.
- Give it air. On a dry, sunny day, pull the cover off for a few hours and let everything breathe.
- Touch up chips early. Sand any rust spot to bare metal and hit it with high-heat paint before it creeps.
Can you cover the grill with a temperature controller attached?
If you run a fan-driven controller like the BBQube TempMaster Pro for hands-off low-and-slow cooks, the fan mounts at the lower vent through an adapter — such as the adjustable lower-vent adapter for the Akorn Kamado. Pop the fan and adapter off before covering; it takes about ten seconds, and the cover then fits the body the way it was designed to. It's a small ritual worth keeping: a covered, dry grill plus a controller that holds 225°F on its own means your Akorn is always ready for an overnight brisket without a 3 a.m. vent check.
How do you clean and store the cover itself?
Hose it down, scrub gently with mild dish soap and a soft brush, rinse, and let it air-dry completely before it goes back on the grill — folding or reinstalling a damp cover defeats the point. Skip the washing machine and harsh solvents, which strip the waterproof coating. Treated this way, a genuinely heavy duty cover should give you several years of service, while a bargain-bin vinyl cover often needs replacing every season or two. Do the math and the better cover is the cheaper cover.
FAQ
Will a 31" x 47" cover fit the Akorn Kamado Jr.?
No — the Akorn Jr. is a much smaller, portable grill, and a full-size cover would swamp it and pool water. The 31-inch diameter, 47-inch tall cover is sized for the full-size Akorn 22 and other large kamados. Measure the Jr. before buying a cover for it.
Can I put the cover on while the grill is still warm?
It's best to wait until the exterior is cool to the touch. Covering a warm grill can degrade the cover's inner lining over time and traps warm, moist air against the steel — exactly the condensation you're trying to avoid.
How do I keep my Akorn from rusting even with a cover on?
Cover the grill only when it's cool and dry, empty the ash pan after every cook, keep the cover's air vents unobstructed, and give the grill an uncovered hour or two on dry days. Touch up paint chips with high-heat paint as soon as you spot them.
Does the cover fit with the side shelves up?
No — fold both side shelves down first. The cover is patterned for the grill's body silhouette, and the shelves folded create a clean, round profile the cover slips right over.
Is a heavy duty cover worth it over a cheap one?
Almost always. Budget vinyl covers typically crack at the seams and go brittle in the sun within a season or two, so you rebuy them repeatedly — and meanwhile the grill they were meant to protect sits exposed. One well-made cover outlasts several cheap ones.
