Product Information

Full details

The Knott 42mm Cast Jockey Wheel Clamp (KT013) is designed for trailer owners and operators who require a robust, heavy-duty mounting solution for their jockey wheels or prop stands. Its primary benefit is the jam-free, cast construction that ensures reliable performance under significant load, though users should note it is specifically engineered for 42mm diameter tubes, limiting compatibility with larger or smaller diameter equipment.

FAQs

Will this fit a 48mm jockey wheel?

No, this clamp is specifically engineered for 42mm diameter jockey wheels or prop stands.

What is the distance between the mounting holes?

The mounting holes are set at 101mm centres.

Is this clamp suitable for off-road trailers?

Yes, its heavy-duty cast construction makes it well-suited for the extra vibration and stress encountered on off-road trailers.

Are mounting bolts included?

No, mounting hardware (bolts and nuts) is typically not included with the clamp; ensure you use M12 high-tensile bolts.

Does the clamp rust easily?

While it is made of heavy-duty cast metal, we recommend periodic inspection and cleaning to prevent surface oxidation, especially if used near saltwater.

Troubleshooting

Clamp handle becomes difficult to turn

Check for debris in the threads and apply a light coat of grease to the spindle.

Jockey wheel slides down under load

Ensure the rubber grip or clamping plate is clean and that the handle is tightened fully to the manufacturer's recommended torque.

Pros and Cons

Pros

  • Extremely durable cast steel material
  • Reliable jam-free locking mechanism
  • Easy to install on most standard trailers
  • Ideal for heavy-duty load bearing
  • Genuine OEM-grade replacement part

Cons

  • Strictly limited to 42mm diameter tubes
  • Heavier than standard pressed-steel clamps
  • Requires specific 101mm centre mounting spacing

Setup, Compatibility & Care

To install the clamp, align the 101mm mounting holes with your trailer's drawbar or chassis mounting bracket. Use high-tensile M12 bolts to ensure a secure fit. Before final tightening, ensure your jockey wheel or prop stand slides freely through the clamp when in the loosened position.

To maintain optimal performance, occasionally clear debris from the threaded handle area and apply a small amount of marine-grade grease to the spindle thread to keep the operation smooth. Check the mounting bolts regularly to ensure they remain tight, as trailer vibration can loosen hardware over time.
