Each block consists of two halves which together creates a square shaped 60 mm long sealing insert. Standard insert blocks are divided up in seven sizes, 15, 20, 30, 40, 60, 90 and 120 mm in square.
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 select insert blocks according to the table.
Blocks are referred to by their width (A) and hole diameter (B). Thus a block with a width of 15 mm (0.59”) and a hole diameter of 4 mm (00.16”) is referred to as 15/4.
