Two screws clamp the band to the wire tong. Each screw is threaded intoa half of the band and engages a slot in the opposite half, permittingthe halves of the band to be separated by a sliding action withoutremoving the screws. The hinge ring slides on the band, permittingrotation of the wire tong when the tong is supported by rope blocks. Forpositive insulation between rope blocks and live conductors, install theband the minimum distance or more for voltage class.
