Napoleon Caster Plug PRO 500 (N510-0014) solves a common frustration for grill owners dealing with loose or unstable wheels. When a caster plug wears out or goes missing, your grill can wobble, shift, or become unsafe to move. This OEM replacement restores a tight, secure fit so your PRO 500 grill rolls smoothly and stays firmly planted when it matters most.
Designed specifically for Napoleon PRO 500 series grills, this factory-original caster plug fits directly into the cart frame to hold the caster shaft in place. Whether you're replacing a single damaged plug or upgrading all four, this small but critical component keeps your grill performing the way it was built to.

With over 35 years of smoking experience, we started DDR BBQ Supply with a simple goal: to help others cook better barbecue. We've spent decades learning what works and what doesn't, and we apply that knowledge to every product we carry. From high-performance grills and smokers to carefully selected rubs, sauces, and tools, everything we offer is something we believe in and use ourselves. We don’t believe in cutting corners or selling gear we wouldn’t rely on during our own backyard cooks and when we compete in BBQ competitions.
