Central Treads/Spacers

Two central treads are available; a half tread and a full flip-up tread. Either tread should be used with the 'Towing Pro-Steps' as this will give the correct angle articulation allowing these to be Type-Approved.

The half tread option is fixed and provides a 4-hole faceplate and socket plate for use with any type of coupling, including standard towballs or Pin and Balls. These are unsuitable for use with PRO-UNI, height-adjustable towbars or height-adjustable couplings.

The full flip-up tread option offers a full central tread solution when not towing. These are designed to achieve type-approval articulation angles and provide 4 hole faceplate and socket plate. The full central tread must be used with a removable ball (on a ball and pin attachment) as the tread will not 'close' with the ball attached. It will close with just the pin attached. The full tread is not suitable with a standard towbar as the tread will not close fully. Please see the image.

These are unsuitable for use with PRO-UNI, height-adjustable towbars or height-adjustable couplings.
