Tow Ball Mounting Collar to secure 10t tow balls

Install a tow ball collar on plates smaller than the 40mm plate. Help prevent the mounting plate from bending under stress loads.

Australian Made10t ball collar solves a problem mounting 10t tow ball mounted on a ute tray back. The customer felt his existing installation needed strength as it would not withstand the loads asserted by a 10t gooseneck coupling.

Ideal when your bedding plate or tow ball platform requires strengthening.

Bed plates used in gooseneck tow balls can be as thin as 10mm as opposed to 35mm.

A collar significantly strengthens the Gooseneck mounting plate area.

This collar is used on plates smaller than the 40mm plate is used to secure the tow ball into position on a utility body.

As a result, this helps prevent the mounting plate from bending or cracking under stress loads.
