Hendrix Vise Top Insulators

Dependable Performance and Delivery

Optimize Your Time and Safety While Avoiding Hidden Costs

Since 1965, Hendrix has been the innovator of HDPE distribution insulators. installed on all 7 continents, Our products have proven themselves repeatedly in the toughest conditions around the world.


Reduce Inventory & Prevent Project Delays

Eliminate ties and the need to carry significant stock thanks to our short lead times and consistent on-time-delivery. Our insulators are proudly made in the USA in Amherst, NH and have a 2-4 week lead time.

Minimize Scrap & Damaged Material

Vise Top insulators won’t chip, crack or break, are vandal resistant, and are even ballistics proof. They are also reusable and recyclable.

Increase Installation Efficiency

Our Vise Top insert design allows it to be used with covered and bare conductor. It’s clamping mechanism with shear bolts reduces installation time by more than half.

Increase Installation Safety & Reliability

Eliminates body injuries due to being 30-40% lighter-weight. Our proprietary compound formulation provides greater track resistance, and we offer optional flame retardant or high temperature material.
