The RDI Endurance Hand Rail System is an ADA-compliant; graspable Hand Rail that provides added safety to any stair or ramp. This vinyl-clad aluminum system is compatible with all other RDI railing products as well as other vinyl, wood, and composite guard rail systems, and it can also be mounted directly to any wall surface. Unlike other systems, this low-maintenance, and easy to install system has no ugly exposed attachment bolts or screws because they are hidden by the included caps and trims, and the complete metal-to-metal connections ensure maximum strength. The Endurance Hand Rail Bracket provides strength and easy installation to virtually any surface. Includes stainless steel screws and mounting bolt cover to provide a clean, finished look (mounting bolt not included). Please note: it is recommended that Hand Rail not exceed 6 ft. between brackets.
