Closure for rectangular aperture in tiled wall

摘要

A frame is insertable into the aperture and is securable at its edges. The frame releasably holds a cover plate (21) and the frame and cover plate are made entirely of plastics. They contain coacting parts of flexible plug connectors, by which the cover plate is secured in the frame. Pref. the plug connectors permit use of a rigidly fitted cover plate, or of a plate hinged to the frame like a door. In the latter instance, the hinges contain corresp. plug connectors. The frame typically consists of corner elements (3) and straight couplers (5).
