Gladhand Lock

The Gladhand lock prevents unauthorized or unintentional movement of a truck trailer by sealing the air intake valve of the trailer’s emergency brake system.

A Gladhand lock is a clear choice as a safety device. Serving as an excellent reminder for drivers to check for completion of loading/unloading or mechanical service before moving the trailer.

The use of a Gladhand lock offers an increased level of theft deterrence. Maximum security can be achieved when used in combination with the DMC High Security TRAILOK™ Kingpin lock and High Security Abloy® padlocks.

 Stocked locks are keyed alike, individually keyed locks are available. Individual keying is per order, lock codes are re-used.

Gladhand locks are offered as a safety device and are intended as a low level security lock.
