Abstract

The invention relates to a catch for a door, especially a switchboard door, with a lock plate which can be secured to the door and bears a door lock and a bolt cover guided adjustably on the lock plate which can be secured in a position covering the door lock by means of a cover lock. Complete sealing with substantially increased security against unauthorized access to the door lock is attained in that the door lock takes the form of a casement lock and the cover lock that of a cylinder lock, a partial cover is secured to the lock plate which overlaps with the bolt cover in the locked position at the contact point and forms a sealed lock cover, and a cover for the cylinder lock is rotatably fitted on the bolt cover.
