The D-Lock (Glad Hand Locking Device) is a safety device designed specifically for use on detached tractor-trailers. This is achieved by locking the air brakes of the tractor-trailer, thus blocking the release of the air brakes and bringing the tractor to a standstill.

• Lockable with 1 padlock
• Never lose the pin again with our Glad Hand Lock with chain.

Each lock is precisely manufactured by hand and finished with a RED WAGON powder coating with a protective finish. The protective finish withstands all weather conditions and the abuse of daily wear and tear.

How does it work?

1. Place the D-Lock over the air supply coupling
2. Lock the Glad Hand D-Lock with a padlock
3. The Trailer is now safe and immobile!
