Tested to ASTM F712. Meet Class 4 requirements. Rated 36.6kV covered-phased-to-covered-phase. Protect personnel when raising or lowering a pole. between energized lines. Cover poles during rubber glove maintenance in confined areas. High-dielectric linear polyethylene covers will not flash flame. This material will have some softening without deformation at approximately 170�F, and it will resist. brittleness at temperatures to -50�F. Pole covers are ribbed to reduce cover contact with the pole, thus minimizing creosote contamination. Nylon button on 4� and 6� lengths allows pole covers to be joined together in tandem, where longer lengths are required Rope handles help to easily spread the covers and snap them around the pole (Rubber gloves must be worn during this procedure) Prolonged contact with an energized conductor must not be allowed Button-Nut Kit, T4060214 Should be used in conjunction with conductor covers when raising or lowering poles.
