Service Insulation Piercing Connector
This connector is designed to connect the insulated service conductors to the low voltage A.B.C. (Aerial Bundled Conductors).
Insulation piercing is carried out on the main and tap conductors simultaneously in a single tightening operation.
Connectors K441, K442 and K443 are fitted with a yellow shear head indicator that disappears when head is sheared-off, being a clear visual confirmation of good tightening from ground level.
