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.
