Saftron anchor socket is made from a specially formulated high impact polymer to ensure longevity and unparalleled resistance to the elements and chemicals. Saftron anchor sockets can be used with any handrail or ladder with a 1.90" OD rail. Saftron anchor sockets work particularly well with Saftron railing due to a firm grip of material when secured together. A grounding terminal is included for installations that have steel rails or other conductive materials. (Saftron rails and ladders do not require bonding/grounding when use with a Saftron rail). Perfect for steel rails when winterizing as the steel rails do not get fused in the anchor socket making it difficult to remove.
