Universal Vise-Top Insulators

Hendrix Vise-Top Insulators are pin-type insulators that incorporate a clamping mechanism into the top of the insulator to provide quick and easy conductor installation without the need for additional tie products. When used with the Stringing Tool, conductors can be installed without separate stringing blocks, significantly reducing installation costs.

Universal Vise-Top insulators are patented second generation designs for improved conductor mounting and gripping performance. They feature a single mounting position for both tangent and angled construction, thereby avoiding the leakage and arc distance reductions of traditional side-neck mounting applications. They also feature an innovative grip design for use with all conductor sizes and types (aluminum, copper or covered).

Universal Vise-Top insulators mount on standard insulator pins and conform with the electrical and mechanical requirements of ANSI C29.5 and C29.6.
