ABSTRACT:
A frame structure for providing a lead-through facility for passing cables or like devices sealingly through a wall or like structure. The frame construction is substantially of rectangular configuration and is intended to be filled with packing pieces made of a material which has a given compressibility, in a manner to present through-passing holes which correspond in size and in number to the size and the number of cables or like devices to be passed through the frame construction. The frame construction includes a plurality of mutually interconnected frame member, namely at least one frame side-piece for each side of the frame, and one corner piece for each corner. The frame construction also includes partition walls which divide the interior of the frame construction into sections substantially perpendicularly to the frame side-pieces in the case of frame sides which are made-up of more than one frame side-piece. The partition walls have the same length as those frame side-pieces that extend parallel therewith. A connector device is provided for connecting mutually adjacent and/or intersecting partition walls one to the other.
