Forming inbuilt recesses for appts. sockets in channels, e.g. in electrical installation conduits - providing perforations around covers with groove-spring coupling over openings in built in installation channels

摘要

Recesses are formed for built-in containers (9) in installation channels (6). The channels (6) have longitudinal openings (7) which can be closed by covers (1) insertable in the openings (7). Perforations, tear lines or fracture lines (Z) are formed in the covers (1) or in the walls (6b) of the channels (6) defining one side of the opening (7) and lying in its plane. The perforations or tear lines (Z) are spaced at a distance (B) from an outer long edge (1a) of the cover (1) or an inner long edge (7a,7b) of the opening (7). The perforations (Z) run perpendicular or parallel to these edges (1a or 7a, 7b). ADVANTAGE - Can be easily adapted to different device models or colours, etc.
