🚤 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
