ABSTRACT:
Anti-pilferage device for box car doors of both the sliding and plug type in which the device is toward the top of the door out of reach of a person standing on the ground and only accessible to release the latch from the top, by a person standing on a loading dock. The latch cooperates with a keeper and both the keeper and latch are enclosed so access cannot be had to the latch to release the latch by a pole or elongated tool and the like.
A pivoted release member is provided for the latch which extends above the latch plates forming a housing for the latch toward the rear ends of said latch plates and is transversely pivoted thereto and is inwardly of the sides of said latch plates to prevent access to said release member by a pole or other tool. The release member has camming engagement with the latch and is operable by hand to cam the latch out of engagement with the keeper and accommodate opening of the door.
