Ribbed Jockey Wheel
Ribbed jockey wheels or as they are also known, serrated jockey wheels, are exactly what they say they are. The ribs or serrations are locked into the clamp to prevent them from sliding when loading or towing your trailer. They are ideal for heavy-duty commercial trailers and will normally require a jockey wheel with a diameter of 48mm or 60mm. Most of these jockey wheels are suitable for 3500kg trailers.
