STOPOUT® Trailer-Lock Glad Hand Lockout Device

Clamp down to stop and prevent unplanned movement of trailers from the dock and storage areas. Deter unauthorized drive-off of trailers by blocking access to the emergency brake airline. Attach the Glad Hand Lockout to the trailer's (red) line connection, and secure with your choice of padlock (sold separately) to control access. This visible red, octagon-shape device is made of durable plastic with a zinc-coated steel pin for the hinge. Fits in the palm of the hand, measuring 4"L x 3"W x 2"H, and is designed to prevent slipping or loosening from tamper attempts. Easy to use, clam-style device its only one way, and it hinges to completely cover the glad hand coupling point valve - fits standard valves. The red, octagon shape over the airline connection reinforces lockout status and conveys stop.
