Clamp for Jockey Wheel – Ø48 mm, Galvanized 4 mm Steel

This Ø48 mm jockey wheel clamp is an essential accessory for almost any trailer equipped with a support wheel or prop stand. The clamp mounts securely to the trailer drawbar or frame using bolts (typically two bolts through the clamp’s base). Once installed, it allows you to fix the jockey wheel’s tube (48 mm diameter) in place by tightening the large screw handle. Built from 4 mm thick steel, it is galvanized to prevent corrosion when exposed to rain, saltwater, and mud. This means the clamp can withstand road vibrations and shocks, as well as the trailer’s weight bearing down on it, without bending or breaking.

Universal compatibility: The 48 mm diameter is the standard for most jockey wheels on boat trailers, caravans, and utility trailers, making this clamp broadly universal. If your trailer did not originally have a jockey wheel, this clamp enables you to add one – you would drill holes in the frame at an appropriate spot (usually at the front of the trailer near the coupler), attach the clamp with bolts and nuts, and you’ll have a mounting point for a jack wheel. If your old clamp is worn out or bent, replacing it with a new one ensures a more secure grip and smoother operation of the screw mechanism.

The large T-handle screw/bolt is designed for ease of use – it allows you to tighten or loosen the clamp’s grip on the jockey wheel by hand, without tools. This is especially handy when adjusting the height: if you want to raise or lower the trailer’s nose, you simply loosen the handle, slide the wheel’s tube to the desired height, and tighten it back up firmly. The screw mechanism has sturdy threads and often a protective cap or plastic handle that makes turning easy even with wet or cold hands.

Safety and recommendations: Always tighten the clamp fully before letting the trailer’s weight rest on the jockey wheel – an insufficiently tightened clamp could allow the wheel to slip and the trailer to drop. Periodically lubricate the screw thread (for example, with a bit of grease) so it turns smoothly and doesn’t gall or wear out. Also check the bolts that secure the clamp to the frame: they should remain tight to avoid any wobble. This EU-made clamp has gone through quality control – its heavy-duty construction ensures long-lasting and safe usage even in harsh conditions. With it, your jockey wheel will be firmly attached and ready to bear the trailer’s weight whenever needed.
