ADA Hand Rail Internal Joiner is a low-maintenance vinyl clad internal joiner designed to shorten installation time when used with the return loop. This vinyl-clad aluminum system is compatible with all other Barrette 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 Internal Joiner is used to join two sections of Hand Rail (model #73030513, 73030514, 73030515) or to join a section of Hand Rail to the Graspable Return Loop (73030519). This joiner ensures strength and stability while providing uninterrupted metal-to-metal connections at all joints and glues easily in place.
