The surface of the mounting tool must not have sharp edges, spikes or other damage that may reduce handling and operational reliability. There must be no spikes, scratches, and protrusions at the points of contact with the conductor. At the points of exit of the wires from the hooks, the edges must be rounded in order not to damage the wire. The value of the permissible load is indicated with the mounting tool. This value refers to a load where the mounting tool or other parts do not permanently deform.
