The non-reversible coupling is still the first-class solution for trailer coupling safety.

In order for it to function as expected, the ball head must be free of paint, rust, or rust buildup. With the new ball head grinder - specifically designed for a wobble-free connection - you can be on the safe side.
After 10-15 seconds it will be completely clear. And you can be sure that you will arrive safely at your destination.

A non-sway coupling must have a completely paint-free, rust-free, clean ball head in order to function perfectly. It must have a bare metal surface that is free of grease. There are no exceptions. Removal of paint and rust and cleaning is mandatory before commissioning. This is required by manufacturers. Otherwise, there is a risk that the friction materials will clog the non-sway coupling with paint and dirt particles, which can prevent 100% functionality.

You can tell this has happened if you hear loud grinding noises from the trailer coupling during shifting or cornering, or perhaps only in a dangerous situation - for example, when an accident is inevitable.
The Kruse Tech ball grinder is used in conjunction with a standard cordless screwdriver directly on the ball end of the trailer coupling. Even at low speed and after a few revolutions, the desired result can be achieved quickly - and the safe operation of the non-wobble coupling is guaranteed.

No need for laborious manual cleaning of the ball head. No sanding, no industrial cleaning agents, no cleaning cloths. From now on, all that can be left to history.

With the Kruse Tech K4708 ball sander and cordless screwdriver, you can clean successfully in seconds.

When used correctly, the abrasive material of a ball sander does not affect the surface of the ball itself, but thanks to its flexible structure, only removes paint, rust and dirt.
