A superior safety device for warehouses to prevent a trailer from being moved while being loaded or unloaded. The glad hand lock is applied to the emergency brake (red) connection of the trailer. This lock must be removed before the air line from the trailer can be connected and thereby release the emergency brakes on the trailer. An excellent way to dead-line a trailer.
