Use Our Tractor Air Brake Lock 30 To Protect Your Unattended Tractor

The WAR-LOK Tractor Air Brake Lock 30 protects idling and parked tractors trailer from theft by completely encasing the parking brake and trailer air valves. 

Tractor Air Brake Lock Exterior

The WAR-LOK Air Brake Lock 30 is made of die-cast aluminum, thus making it nearly impenetrable.

Tractor Air Brake Lock Interior

This tractor-trailer lock device completely covers a tractor's air valve knobs. Equally important, its fortified exterior comes complete with two internal disks that will detach and spin if a thief attempts to drill into the lock. Additionally, like all WAR-LOK products, the Air Brake Lock comes with a nine-cylinder disk locking mechanism, making it nearly impossible for a thief to pick your lock. 

Keyed Alike Tractor Air Brake Locks

Air Brake Locks can be keyed differently, keyed alike, or keyed alike to a master key. Furthermore, newly purchased locks can be keyed alike to an existing lock. Ownership will be verified by WAR-LOK before any key is copied. Not to mention, our keys are cut at our WAR-LOK Assembly Shop, located in Dallas, Texas, USA.

2. Using the 1/8″ Allen wrench provided, adjust until the vinyl tip is touching the back of the knob. (This is a one-time adjustment.)
3. If you are using the standard red and yellow knobs, install the self-stick foam pads in the inner body.
4. If you are using the large chrome knobs, discard the foam pads.

To install the lock:

2. Slide the other half in place until the two halves are together.

Best lock ever

Best lock to prevent theft. Were a towing company so even if were on the side of the road we can lock the air brakes while were under the truck broke down disconnecting the drive shaft. Just got make sure the key is lined up or you well go nuts. Once you get hang of it piece of cake. When the trucks are out back at night you don't have second guess if some one well get your million dollar rotator. Thanks war-lock
