Abstract
A fireproof lead-through with a frame, comprising at least one frame half for fitting on one side of a wall with a rectangularly shaped pack of packing blocks through which cables pass filling the opening in each frame half, and engaging with it peripheral portions in channel-like profiled portions in each frame half. Stay strips with a special configuration engage with their ends in the profiled portions for stiffening the pack of blocks. The transit is made pressure-tight by the use of conventional wedging means or pouring composition.
