Our range of blocks accomodates cables between 4 and 100 mm in diameter. It is important that the insert block is the right size, with respect to the cable, to ensure a proper seal. Measure the cable diameters carefully and choose insert blocks accordingly. With the sizing chart on below you can choose the correct size of insert blocks. Blocks are referred to by their width (A) and hole diameter (B). Thus a block with a width of 15 mm and a hole diameter of 4 mm is referred to as 15/4. This designation is moulded into the block.
