Trailer Air Coupling Lock

As a trusted supplier of security seals for the transport and logistics industry, we are excited to now offer the Trailer Air Coupling Lock, available through our role as an official distributor for ASSA ABLOY.

Designed to enhance security and safety in truck and industrial airline applications, this lock effectively seals the air brake airline fitting, preventing unauthorised connection to opposing fittings. It also reduces the risk of accidental trailer connections to trucks, ensuring a safer shutdown by preventing unintended equipment connections during maintenance.

The lock is available in two models to suit both ½” NPT female and male air couplings.
