摘要

A feed through ducting arrangement comprises elastic fitting members (4, 4') which fill up the empty space of the wall opening (2) and which seal under pressure against each other and on the one hand against the conduits (1) and on the other hand against the soffit (5) of the wall opening (2). For producing that pressure, disposed on the side of the wall having the larger cross-section of opening is a clamping flange (6) which extends around the periphery of the opening and which at least partially engages over the fitting members (4, 4') on the front end thereof, from the edge of the opening. The clamping flange (6) can be axially tightened towards the wall (3.1) and presses the fitting member (4, 4') axially into the reducing wall opening (2). IMAGE
