Are the shrink tubing sets for multi-pair splice coding. The fixing length of the shrink tubing is 90 mm, the shrinking rate 3:1. For enduring readability in extreme conditions we recommend that a 120 mm long piece of the transparent BT-48/TR, or the BT-95/TR for the somewhat thicker speaker coding, be used to cover the labels.
