onlyfire Rotisserie Ring Kit for 18–18.5" Kettle Grills — 110V Motor, 20 lb Capacity

The onlyfire Rotisserie Ring Kit converts an 18–18.5" Weber-style kettle into a powered rotisserie for evenly roasted whole chickens, roasts, and large cuts.

If you want reliable rotisserie performance without replacing your kettle, this kit supplies a ring that seats inside the grill, a robust one-piece spit, reversing electric motor, sturdy forks and a heat-resistant finish. The ring's hemmed edge improves fit and helps stabilize temperature control, while the motor is rated to turn loads up to about 20 pounds and includes an auto-reverse feature to reduce meat twisting.

How does the ring improve rotisserie fit and temperature control?

The redesigned ring has a hem on its lower edge so it nests more snugly on the grill lip, reducing wobble and gaps that let heat escape. A closer fit helps the charcoal bed maintain consistent heat during long cooks and keeps the rotisserie level for even rotation.

• Hemmed bottom edge for a tighter seal against the kettle rim
• High-temperature black coating to resist rust and ash exposure
• Compatibility tuned for 18–18.5" outer-diameter kettles (not for WSM models)

What motor and spit hardware are included, and how durable are they?

The kit includes a 110V electric motor with a waterproof on/off switch and built-in auto-reverse to distribute wear and keep meat from binding on the spit. The spit itself is a one-piece 5/16" square rod for added strength, and the forks are heavy-duty four-prong designs that lock meat securely.

• 110V motor rated to rotate up to ~20 lbs with reverse function
• One-piece 5/16" square spit rod for rigidity and simple cleaning
• Two adjustable four-prong forks to hold different-sized cuts

How easy is installation and everyday use?

Installation is straightforward: set the ring into the kettle, mount the motor on the rim, insert the spit through the forks and meat, then engage the motor. The parts are designed for repeated assembly and disassembly, and the coating on the ring and hardware makes post-cook cleanup easier.

• Quick ring placement — no welding or permanent modification
• Simple spit and fork assembly with a handle for inserting/removing meat
• Motor plugs into standard 110V outlets and includes a waterproof switch

Who is this for? The onlyfire Rotisserie Ring Kit suits backyard grillers who own an 18–18.5" charcoal kettle (like many Weber 18" models) and want rotisserie capability without buying a new grill. It's best for users who roast whole poultry, medium-sized roasts or large cuts up to roughly 20 pounds, and for those who prefer a removable, no-drill solution that improves heat retention and rotation stability.

Before purchasing, verify your kettle's outer diameter falls within 18–18.5 inches and note this kit is not compatible with Weber Smokey Mountain (WSM) cookers. The package includes a coated steel ring, one 5/16" square spit rod, the electric motor, two four-prong forks, and a manual handle — everything needed to start rotisserie cooking on most 18" kettles.
