BBQ-PLUS Locking Caster Wheels Set of 4 — Direct-Fit for Weber Spirit/Genesis/Summit, Includes Inserts

These are four replacement locking caster wheels with inserts designed to directly replace Weber model 70360/79500 and fit specified Spirit, Genesis, Summit and compatible grills.

If a broken or seized wheel is preventing you from moving your grill safely, this BBQ-PLUS kit restores mobility and locking stability without modifying the cart. The kit includes four locking wheels plus four matching caster inserts sized to match the factory openings used by many Weber models from the late 2000s and several compatible Napoleon grills. These parts are intended as direct-fit replacements — check measurements and model fit lists before ordering.

Which grill models will these caster wheels fit?

This set is engineered to match the OEM fit used on many Weber Spirit (2009–2012), Genesis (2007–2011) and Summit (2007–2011) carts, plus selected Napoleon Rogue and Prestige models. The listing includes many specific Genesis and Summit model variations across LP and NG configurations for reference.

• Designed to replace Weber original part numbers 70360 and 79500.
• Compatible with listed Spirit, Genesis and Summit year ranges and many model numbers.
• Also suitable for some Napoleon Rogue Series and Prestige 500 grills.
• Always verify your grill’s model number and compare the insert and wheel dimensions.

What are the exact sizes and components included in the kit?

The package contains four locking caster wheels and four matching caster inserts. Knowing the dimensions helps confirm fitment: the outer diameter of each caster measures approximately 2.84 inches by 4.5 inches, while the insert measures about 1.3 inches by 2.28 inches. These measurements match the openings used on the compatible grill carts.

• 4 locking caster wheels for secure parking and movement control.
• 4 caster inserts sized for factory cart openings.
• Outer caster size ~2.84" x 4.5"; insert ~1.3" x 2.28".
• Sold as a set — no additional hardware included unless specified.

How do these casters perform and how do I install them?

The locking mechanism keeps the grill stable when parked and releases for smooth rolling when relocated. Installation is straightforward: remove the old wheel and pull out the existing insert, then press the new insert into the cart opening and snap the caster into place. Minor tools may be helpful but most installs are quick and require no welding or permanent modifications.

• Lock feature secures grill to prevent unwanted rolling.
• Press-fit inserts eliminate need for drilling or welding.
• Installation usually takes minutes per wheel with basic tools.
• Inspect posts and openings for rust or damage before installing.

What should I check before buying replacement wheel parts?

Confirm compatibility by checking your grill’s model number, comparing the old caster/insert dimensions, and ensuring mounting openings match the listed measurements. If your grill has aftermarket modifications, measurements become even more important to guarantee a correct fit. If uncertain, contact the seller with your grill model and photos for assistance.

• Verify grill model and year against the fit list.
• Measure the existing caster and insert diameters before ordering.
• Check for any cart damage that could affect new part seating.
• Reach out to customer service for fit questions prior to purchase.
