SAFTRON high impact polymer products are made of specially formulated compounds to ensure longevity and unparalleled resistance to the elements, UV, and chemicals. SAFTRON Anchor Sockets can be used with any handrail or ladder with a 1.90" OD rail. A grounding terminal is included for installations with steel rails or other conductive materials. (SAFTRON rails and ladders do not require grounding). SAFTRON Anchor Sockets work particularly well with SAFTRON railing due to a firm grip of material when secured together. A high impact polymer exterior ensures SAFTRON products are unaffected by pool chemicals, salt, and sun and remain cooler to the touch.
