▪ Do not overlap the wire clips. Lapping on the wires before and after the clamp is allowed:
▪ Do not use wire clamps for overhead ground wires;
▪ After the initial installation, do not use the wire clamp again:
▪ The direction of rotation of the wire clamp and the wire should be the same. The standard clamp is right-handed, if you need left-handed products, please consult the company.
