GMR Vehicle Restraint System

George Shrokman Jr  is proud to represent the very simple and effect GMR Safety Power Chock.  This rugged and simple truck safety device is the best that we have seen over the last 30 years!  This is a great replacement for ALL of the troublesome restraining devices on the market. 

Simple and Effective


The power chock restraint has gone through years of development and perfection.

You can see from the picture that this is a very simple and well constructed unit.  It is built to take a beating!
