Welcome to the Prolock Website

Prolock is the simple answer to wheel loss in commercial vehicles.
The problem of wheel detachment on trucks and buses has occupied fleet engineers and transport specialists for many years. Much has been written, many tests conducted and a number of products developed to combat the problem. Yet wheels STILL come off.

Some companies view the matter very seriously, others fit some sort of device to pacify VOSA and HSE, others again take the approach that 'it's never happened to us'. Nevertheless, wheels STILL come off – in some cases causing injuries and even fatalities.

Prolock solves the problem. Not just an indicator, not a complicated device, not an expensive technological wonder, simply a clamp that locks on to two adjacent wheel nuts to stop them coming off.
