Abstract
An elongated channel protector has an end wall that precludes axial displacement of the protector along an elongated rail car plug door operating handle in one direction. Angle shaped members extend from the protector laterally for engaging a cover appurtenance on the door for precluding axial displacement of the protector in the opposite direction. A pair of legs depend from the protector side walls and have aligned holes for receiving a bolt seal. Tubular elements surround the holes to protect the seal head and locking body. The seal is seated beneath the handle which is covered by the protector locking the protector to the handle.
