United Pacific Industries Glad Hand Lock Chrome 90618

Heavy-Duty Glad Hand Lock 90618

This chrome-plated aluminium lock secures the glad-hand couplings on commercial trailers and heavy-duty trucks. It prevents unauthorised connection or disconnection of the air-brake lines during parking or storage. Fleet operators and owner-drivers use it to meet security and safety requirements on articulated vehicles. The unit fits standard glad-hand bodies without modification.

Simple Installation With Basic Tools

The lock slides over the glad-hand face and is secured by tightening the integrated set screw with a common hex key. No drilling, welding or specialised tooling is required, so a single technician can fit it in minutes. Corrosion can seize the screw threads if the lock is left exposed to road salt for long periods; occasional lubrication keeps the mechanism free. Verify the glad-hand face is clean and undamaged before fitting, otherwise the lock may not seat squarely and could work loose under vibration.
