Appliance caster assembly for Napoleon grills

This caster assembly supplies two casters and matching plugs for compatible Napoleon grill models. It is intended for owners of the UP405RB, U405, UH405 or U405RB who need to replace worn or damaged wheel hardware. The part restores mobility so the grill can be moved across a patio or deck with minimal effort.

Fits four Napoleon models without modification

The assembly bolts directly to the frame of the listed grills using the existing mounting points. No drilling, welding or additional brackets are required, which keeps installation time short. Once fitted, the original locking mechanism engages as designed, so the grill stays stationary during cooking and moves freely when unlocked.

Two casters share the load during regular

Each wheel carries roughly half the grill weight, reducing stress on any single caster during frequent moves across uneven surfaces. The paired design helps maintain alignment over repeated use, limiting wobble that can develop when a single replacement wheel is mixed with an older mate. The plugs seal the unused mounting holes to keep debris out of the chassis.
