Upgrading a classic charcoal kettle unlocks capabilities far beyond standard direct grilling, but choosing the right onlyfire weber 22 grill accessories requires matching your preferred cooking technique with the appropriate hardware. Many kettle owners want to expand their setup to handle whole roasts, authentic stone-baked pizzas, slow-smoked ribs, or high-heat steak searing. Because each attachment alters internal air volume, fuel access, and lid placement, identifying the best onlyfire accessories for weber 22 setups depends on whether your priority is motorized spit roasting, vertical hanging, or heavy contact searing.

The Onlyfire accessory range for 22-inch kettles is divided into three distinct operational categories: motorized rotisserie rings, vertical smoker extensions, and modular cast-iron cooking surfaces. Within the rotisserie category, the manufacturer provides multiple tiers ranging from standard spit roasters to specialized combo kits that integrate dedicated pizza doors or indirect heat management tools. Knowing how each model mounts to a webber charcoal grill helps avoid purchasing overlapping attachments and ensures seamless integration with your existing outdoor cooking station.

The onlyfire Stainless Steel Multi-purpose Rotisserie is an engineered dual-purpose conversion ring holding U.S. Patent No. 10,405,699. Designed specifically for 22-inch kettle cookers, this onlyfire multi-purpose rotisserie and pizza combo kit includes an electric 110-volt motor, a stainless steel ring, an integrated ring thermometer, a 15-inch cordierite pizza stone, an aluminum pizza peel, and four grate support chips. The unit features an adjustable front access door that allows users to slide pizzas in and out without lifting the heavy kettle lid, preserving internal dome temperatures during baking cycles.

Beyond baking, this kit operates as a dedicated spit roaster capable of cooking two chickens or large roasts at once. The stainless steel dampers can swivel shut to prevent unwanted heat escape when switching between roasting and high-temperature pizza cooking. The motor runs on 110 volts with a power consumption of 4 watts, turning the skewer evenly across the coals. Support tabs included in the kit allow flexible cooking grate positioning either at the bottom near the coals or elevated near the top ring opening.

This model is ideal for backyard entertainers who want both artisan pizza baking and motorized spit roasting in a single purchase without storing separate attachments. It replaces the need for independent pizza conversion rings while retaining full rotisserie functionality. However, the listing explicitly notes that it does not fit 22-inch Slow ‘N Sear kettle grills or the Weber Smokey Mountain cooker. If your cooking regimen does not involve baking stone pizzas, the simpler single-purpose rotisserie rings provide identical roasting capacity with fewer separate loose parts.

onlyfire Stainless Steel Rotisserie Ring Kit

The onlyfire Stainless Steel Rotisserie Ring Kit is built to replace the standard Weber 2290 attachment on 22-1/2-inch charcoal kettle cookers. Constructed from brushed stainless steel, this onlyfire weber 22 rotisserie setup includes the main structural ring, a standard 5/16-inch stainless steel square spit rod, an electric motor with mounting bracket, a counterbalance with bushing hardware, two 4-prong meat forks, and a heat-resistant handle. The total shipping weight sits at 11 pounds, providing a rigid base that elevates the kettle lid to create adequate clearance for bulky meats.

The included 110-volt electric motor delivers 360-degree rotation and is rated to support up to 20 pounds of meat. Constant rotation allows natural self-basting as rendered fats recirculate across the exterior surface, keeping whole poultry, pork loins, and prime ribs moist during slow charcoal cooks. The listing notes that the ring is engineered with a standard fit profile that may leave a slight gap between the ring bottom and the kettle rim. This small opening can result in minor heat loss and may require slight vent adjustments or a temporary aluminum foil seal during extended cooks.

This onlyfire stainless steel rotisserie ring kit suits outdoor cooks seeking an entry point into motorized roasting without extraneous accessories. It is engineered strictly for standard rotisserie tasks like whole chickens, kebabs, and roasts. If you require tighter factory tolerances without managing small rim gaps, or if you prefer bundled fuel containers, this model gives way to the upgraded and sealed versions within the lineup.

onlyfire Stainless Steel BBQ Cooking Smoking

The onlyfire Stainless Steel BBQ Cooking Smoking attachment transforms a standard kettle base into an expansive vertical drum smoker. The main barrel measures 23 inches in diameter by 15.7 inches in height, while the accompanying rib rack measures 21.5 inches in diameter by 5.4 inches tall. Fabricated from heavy-gauge stainless steel with an overall weight of 18.91 pounds, this onlyfire bbq cooking smoking attachment adds vertical volume to accommodate long cuts of meat that normally do not fit horizontally on a standard 22-inch grate.

The internal setup features a 3-tier rib hanger equipped with 24 individual hanging hooks. This layout allows pitmasters to hang multiple full racks of ribs, whole chickens, sausages, or pork loins vertically over indirect heat for even smoke penetration. The exterior barrel incorporates a hinged front access door with an insulated handle, enabling direct charcoal and wood chunk replenishment mid-cook without removing the top lid or lifting out the hanging meat tree. This access preserves stable pit temperatures during prolonged smoking sessions on your bbq grill weber charcoal setup.

This vertical smoker extension suits high-volume barbecue enthusiasts who regularly smoke multiple slabs of ribs or batches of poultry and find flat grates restrictive. Note that the listing states the standard flat cooking grate is not included in the package. The unit is designed for Weber 22.5-inch Original Kettle, Original Kettle Premium, and Performer Premium models, but does not fit the Weber Smokey Mountain or 22-inch Slow ‘N Sear grills.

onlyfire Upgrade Stainless Steel Rotisserie Ring

Best for: Turnkey indirect roasting with grease management

Pros

• Includes two charcoal baskets
• Supplied with 10 drip pans
• Powerful 110-volt electric motor

Cons

• Higher total storage volume

The onlyfire Upgrade Stainless Steel Rotisserie Ring (model 6110) expands the core rotisserie concept by incorporating dedicated indirect heat accessories into the box. Measuring 23 by 23 by 7 inches with a weight of 12.12 pounds, this onlyfire upgrade stainless steel rotisserie package contains the stainless steel extension ring, a 110-volt electric motor holding up to 20 pounds, two heavy-duty charcoal baskets, and 10 disposable aluminum drip pans. The kit fits standard 22-1/2-inch kettle grills from Weber and equivalent brand designs.

The inclusion of twin charcoal holders allows immediate configuration for two-zone indirect roasting. Positioning the baskets on opposing sides of the kettle bowl creates a central convection zone where the rotating spit operates without direct exposure to open embers. The 10 disposable aluminum drip pans sit directly beneath the spit rod to capture dripping oils and fats, protecting the kettle bowl from grease buildup while simplifying clean-up after heavy cooking sessions. The 360-degree rotating spit holds up to two whole chickens simultaneously.

This bundled model is ideal for cooks who want a complete, ready-to-run roasting system right out of the box without sourcing third-party drip trays or fuel separators. It eliminates guesswork regarding fire placement during long roasts. Buyers who already own indirect charcoal baskets or specialized heat deflectors may prefer the standalone rotisserie ring to avoid redundant accessories.

onlyfire Stainless Steel Weber Kettle Rotisserie

The onlyfire Stainless Steel Weber Kettle Rotisserie represents the brand’s refined standalone rotisserie design, engineered specifically for improved rim fitment and enhanced temperature stability. Constructed from polished stainless steel with a finished weight of 12 pounds, this unit includes the main riser ring, a 5/16-inch square spit rod, a 110-volt electric motor rated for 20 pounds, a motor mounting bracket, a counterbalance assembly, two 4-prong meat forks, and a heavy handle.

In this onlyfire grill accessory comparison, this specific model features tighter manufacturing tolerances along the bottom rim compared to the base ring kit, minimizing air infiltration around the kettle lip. The improved fit gives pitmasters tighter control over intake air and combustion rates, maintaining steady cooking temperatures throughout multi-hour cooks. The polished stainless steel frame provides superior heat retention, ensuring radiant warmth remains centered on the spinning spit assembly.

This model is best suited for experienced kettle owners who prioritize precise draft control and stable low-and-slow roasting over multi-function doors or bundled add-ons. It serves cooks focusing exclusively on whole poultry, porchetta, and large roasts. It gives way to the multi-purpose combo kit if you require an integrated front port for pizza baking.

onlyfire 2-in-1 Cast Iron Grill Grate

Best for: High-heat searing and direct charcoal grilling

Pros

• Heavy heat-retaining cast iron
• Removable center sear insert
• Raised handles for fuel reloads

Cons

• Requires regular oil seasoning

The onlyfire 2-in-1 Cast Iron Grill Grate is a direct replacement cooking surface designed for 22.5-inch kettle configurations, including the Original Kettle, Original Kettle Premium, and Performer Premium. Built entirely of heavy cast iron with a total weight of 8 pounds, this onlyfire 2-in-1 cast iron grill grate features an outer ring measuring 21.5 inches in diameter and a removable inner circular sear insert measuring 11.8 inches in diameter. It directly replaces Weber Gourmet BBQ System wire grates with high-mass cast iron.

The heavy cast iron construction provides superior thermal retention compared to standard nickel-plated wire grates, storing heat to deliver bold, professional sear marks on steaks, chops, and vegetables. The inner sear grate is engineered with raised side handles, allowing cooks to lift out the center insert using heat-resistant gloves or tongs to drop fresh charcoal briquettes directly into the fire bed without removing food resting on the outer ring. Maintaining the seasoned iron surface with a dedicated weber grill brush 12 inch protects the metal from oxidation and debris buildup between grilling sessions.

This accessory is the definitive choice for high-heat direct grilling enthusiasts deciding which onlyfire grill accessory to buy for searing steaks, burgers, and vegetables. It does not elevate the kettle lid or support motorized spinning, making it an entirely different operational category from the ring extensions. Outdoor cooks who primarily smoke large cuts or roast whole birds should choose a ring extension, whereas those seeking maximum surface heat transfer will benefit most from this cast-iron upgrade.

Before You Buy

Before purchasing any Onlyfire kettle attachment, verify the exact model and rim profile of your charcoal grill. The manufacturer explicitly states across its product listings that these accessories do not fit the 22-inch Weber Smokey Mountain Cooker or the 22-inch Slow ‘N Sear (SNS) kettle grill. The diameter dimensions and rim lips on those specific cookers differ from standard Weber 22.5-inch Original, Premium, and Performer kettles, preventing the rings and grates from seating properly. Additionally, note that the vertical BBQ smoking attachment does not include a flat wire cooking grate; it is supplied strictly as a hanging barrel with hooks, requiring you to repurpose your existing kettle grate if you want a flat cooking level.

Operational requirements also vary by accessory type and require advance preparation. All Onlyfire rotisserie kits require access to a standard 110-volt electrical outlet to power the spit motors, meaning outdoor extension cords or outdoor-rated power connections are necessary. For the base rotisserie model, the listing notes that a small fit gap may exist between the ring and kettle rim, which might necessitate user-installed high-temp gaskets or foil to prevent draft leakage. For the 2-in-1 cast iron grate, the listing specifies a painted finish on raw cast iron, requiring periodic cleaning, drying, and oil seasoning to maintain the surface and prevent rust.

FAQ

Do Onlyfire rotisserie rings fit the Weber Smokey Mountain Cooker?

No. The product listings explicitly note across all rotisserie and smoking models that they do not fit the Weber Smokey Mountain Cooker or the 22-inch Slow ‘N Sear kettle grill. They are manufactured specifically for standard Weber 22.5-inch charcoal kettles such as the Original Kettle, Original Kettle Premium, and Performer series.

How much weight can the Onlyfire rotisserie motor turn?

The standard 110-volt electric rotisserie motors supplied across Onlyfire’s kettle kits are rated to support up to 20 pounds of balanced meat. The listings note this capacity is sufficient to roast up to two whole chickens or large roasts simultaneously using the included 4-prong meat forks and counterbalance assembly.

Can you bake pizza on the multi-purpose kit without running the rotisserie motor?

Yes. The multi-purpose kit functions independently as either a pizza oven or a rotisserie roaster. When baking pizzas, the spit rod and motor can be set aside, allowing you to insert the 15-inch pizza stone on the support clips and access the cooking surface directly through the front opening door with the included aluminum peel.

Does the Onlyfire vertical smoking attachment include a standard cooking grate?

No. The listing explicitly states that a cooking grate is not included with the smoking attachment. The package includes the 15.7-inch stainless steel riser ring, the access door, and the 3-tier rib hanger with 24 hanging hooks. If you want a flat horizontal surface inside the barrel, you must supply your own compatible 21.5-inch grate.

How do you add charcoal when using the 2-in-1 cast iron grill grate?

The 2-in-1 cast iron grate features an 11.8-inch removable center sear insert equipped with raised side handles. During a cook, you can lift out this central insert using heat-resistant tools to drop charcoal briquettes or wood chunks directly into the fuel bed below without moving food arranged on the 21.5-inch outer ring.
