This is the inside handle for Bargman L-54 and L-55 locks when the lock box is installed on the interior face of the trailer door, like on some Spartans. This handle is not used when the lock box installation is hidden inside the door void, like on Airstreams.
The 4-3/8" long handle fits on the lock's 3/8" shaft with chamfered corners. It is secured with a 1/2" long slotted oval head machine screw (not included).
Solid cast zinc and zinc plated.
Lifetime Warranty against breakage.
