The PA66HIRHSUV Aerial Support Ties from HellermannTyton feature a built-in spacer to separate cables from the support wire and prevent abrasion. A one-piece design, combining the tie and spacer into one part, reduces installation time and inventory costs. The outside serrations along the strap prevent damage to cables. Formulated from a special nylon blend, these ties are specifically suited for long-term outdoor use. The bent tail allows for quick and simple installation by hand.
