With the high cost of vehicles, basic theft protection is a necessity! In order to ensure that tractors and trucks will not be stolen when left unattended, CGM has introduced the patented TS4A tractor air brake lock.  This device basically locks the emergency brake valve in place, so that once the brakes are set, no one can move the vehicle. The device is seamless to the operation of the normal Haldex or Bendix air valve.  It is a resident system with no moving parts and nothing to assemble in order to use it. To operate the device, the driver simple removes the key.  The device cannot be used unless the truck is parked and the air lines are bled.  The device can be moved from truck to truck and never wears out.  It is designed to fit most trucks including all tractors, yard dogs, dump trucks, garbage and fire trucks, busses and any straight truck with air brakes. Assembly is quick and easy and can be done in under 20 minutes for a first timer!

The device requires NO DRIVER ASSEMBLY. Unlike the plastic cuff products, this device cannot be removed with a lighter or flat head screwdriver. In fact with thousands installed we have never had a truck stolen with it in place.

The theft of tractors, dump trucks and tractor/trailer rigs happens daily at trucks stops and on your own yards. Millions in cargo are lost to companies in about 90 seconds for an unattended rig! Besides the loads, tractors and trailers are always taken and frequently damaged or destroyed.  Insurance does not cover incidents where employee infidelity is the root cause of theft. Self protection methods are the only way to insure that you are protected.  Recovery of your assets becomes unlikely, not to mention the collateral damage to your clients, your ability to do business and the loss of your assets.

Releasing of the tractors emergency brake system is the only way to move a rig. Disabling that system through a clean, simple and effective tool makes this investment a must for the individual owner and fleets alike!  

These devices come with all mounting brackets, two security keys and all fittings. Specify truck type when ordering.
