Now this is a sneaky important part. Most people don’t even know it exists… until their wheel falls out. The Napoleon N510-0015 Caster Socket Insert is the small-but-critical piece that locks your caster wheels into the grill frame. No insert? No proper fit. And suddenly your “mobile grill” is doing trust falls.

This OEM part presses into the bottom of the cart leg and creates a snug home for the caster shaft—keeping your grill stable when parked and smooth when moving. It’s one of those parts you never think about… until you really, really need it.

• Genuine Napoleon OEM part
• Secures caster wheels into the cart frame
• Fits Rogue-style carts (365 / 425 / 525 / 625)
• Simple press-in install—no tools required

Because wheels are great… when they actually stay attached

• These wear out, crack from bashing the grill over pavers, or go missing during moves
• Without it, the caster won’t seat properly
