The All-Terrain Wheel Chocks are heavy-duty rubber stoppers custom made to halt your All-Terrain Silverbac or Kamado in its tracks! Jam these chocks into the wheels of your AT and rest assured it’s not moving anywhere during your cook. They’re constructed of roughly 1.5lbs of solid rubber, have textured surfaces for grip and are tied together for added security. The chocks are even great to make sure your grill stays put on even surfaces, keeping it stable when someone bumps it. Lock down your grill and keep it stable with the All-Terrain Wheel Chocks.
