Abstract
In a lead-through transit for cables or pipes 3 of the kind in which a series of modular resilient blocks 4 or blanks 5 are mounted in a frame 1 through which the cables 3 extend, the invention is directed to the compression and packer assembly 7 by which the opening through the frame 1 is closed and pressure applied to the assembled cables 3, blocks 4 and blanks 5 with stayplates 6 between each row of blocks. The compression and packer assembly 7 comprises a rigid plate 8 which seats on the assembled blocks 4 and blanks 5 for engagement by a compression bolt 33 mounted on the frame 1 to apply a load to the plate 8. Three resilient packer blocks 9,10 and 11 are arranged to be inserted between the plate 8 and frame 1 with two of the blocks 9,11 being for insertion on either side of the bolt 33 and having respective distance members as rods 28 to limit the reactive effect of the assembled blocks 4 and blanks 5 with cables 3 so that the compression bolt 33 can be displaced clear of the center of the frame 1 to leave a clearance spaced into which the center packer block 10 is inserted. Each packer block 9,10 and 11 has an associated compressor stud 12,13 and 14 which acts to compress i…
