The SĀFTRON Figure-4 3 Bend Return-to-Deck Handrail comes in classic or fully reinforced, which contains encapsulated steel (classic model) or encapsulated aluminum (fully reinforced model) to provide superior strength and durability. A high impact polymer exterior ensures SĀFTRON rails are unaffected by pool chemicals, salt, and sun and remain cooler to the touch. No grounding or bonding is required.
