Patent attributes
A transit device is disclosed for passing at least one elongate line sealingly through an opening in a wall. The device comprises a clamping frame and a number of blocks which together fill-out the frame. At least one of the blocks has a through-penetrating channel for receiving the line, wherein the block is adapted to permit lateral insertion of the line into the channel. The device also comprises a separate tubular bush made of elastic material. The bush has a generally axial through-penetrating slot in its wall, to enable the bush to be laterally fitted to the line, and has an outer cross-section which corresponds generally to the cross-section of the channel in the block. The bush comprises a plurality of radially separated layers which can be separated from each other so as to adapt the through-penetrating channel of the bush to the line.
