Wheel Safety Device

The device known in some countries as Rollock is marketed exclusively in the UK by Parma Industries using the registered Trade Mark Prolock.
This is an effective wheel safety device which locks two adjacent wheel nuts together to prevent wheel detachment in the event of loss of clamping force in the wheel fixings.
