Wall feedthrough for pipes, cables or electrical wiring - incorporates conduit through hollow bodies driven into opposite faces of wall and held together by rods

摘要

The two hollow bodies (3,4) are fitted into opposite ends of a hole (2) through the wall (1) and joined together elastically by a synthetic tube (10). Each body is secured to its face of the wall by a flanged disc (6,8) contg. holes for two or more tensioning rods (11). The head of each rod is driven tightly into one disc (6), so that its threaded free end protrudes through a hole in the other disc (8) and is secured by a nut (12). ADVANTAGE - Simple construction guarantees reliable seal over long period without supplementary filling.
