Abstract: A pole climber assembly that helps prevent the user from being electrocuted by contact of any part of the assembly with an electrical source. The assembly includes a hook or stirrup which is molded of a nonconductive composite material. The composite material has the strength of a stell stirrup. Other features of the assembly include calf pads and straps that may be made of nylon, a non-skid thermoplastic pad on the exterior side of the stirrup to prevent wear of the composite material resulting from walking use, and an adjustable section allowing the pole climber to be adapted to users of any height.
