Lockwood TL Series Air Coupling Lock (Truck Lock)

The Lockwood Air Coupling Locks have been designed for the securing of Truck (Trailer) and industrial compressed air line applications.When attached to the air line this product provides security and safety.

Security
Whereby the air brakes air line fitting is effectively sealed when the lock is attached, preventing connection to the opposing fitting. In the case of a trailer application this reduces the risk of the trailer being connected to a truck without authorisation.

Safety
In an industrial application the sealing of the air line can reduce the risk of an accidental connection of equipment when shut down for maintenance etc.

Range
The Lockwood Air Coupling Lock range consists of two series, the AL Series and the TL series. The AL Series comes with an integrated cylinder that can be keyed to most restricted key systems while the TL Series is designed to be locked with a padlock.

The TL Series is available in two models to suit both the ½” NPT female air coupling and the ½” NPT male air coupling.
TL Series Features

  • Case hardened steel outer sleeve
  • Spring loaded function, allowing for quick snap-on attachment to ½ inch male air coupling fittings
  • Models to suit ½” NPT female and the ½” NPT male air couplings
