🚤 Compatibility & Application

  

• Heavy boat trailers, caravans and off-road trailers requiring a long-body 750kg jockey wheel

• The 750kg figure is a supported static drawbar-load rating, not trailer ATM

• Confirm drawbar size, mounting clearance, wheel sweep and ground clearance before installation

• Mounting hardware must be tightened evenly and rechecked after initial use

• Fully raise and positively lock the yoke before road travel

  

🔌 Function

  

Supports the uncoupled trailer drawbar, adjusts coupling height and allows controlled low-speed manoeuvring on firm or moderately uneven ground.

• Yoke does not lock positively in the selected position

• Side-wind screw binds, skips or develops excessive free play

• Sealed wheel bearings become loose, noisy or difficult to rotate

• Clamp or mounting plates shift on the drawbar

• Zinc coating is damaged and structural corrosion develops
