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 RDI endurance powder-coated cast aluminum post return creates a smooth termination at any post or wall and the included snap-fit vinyl cover plate conceals fasteners for a clean, finished look. The post return provides a closed end to the railing preventing clothing or other objects from hooking onto the rail end. A 3 in. aluminum joiner is also included to provide added strength and ensure a quick connection to other endurance hand rail components.
