Aluminum Secondary Hand Rail External Adjustable Joiner by RDI
What It Is
This is an external adjustable joiner designed for aluminum secondary hand rail systems. It’s used to connect two sections of aluminum handrail at a custom angle — especially where the rail needs to turn around an outside corner or follow a sloped path.
Key Features
- Adjustable Angle: Allows you to join handrail sections at variable angles (commonly up to 90°) without making precise miter cuts in the rail itself, making installs easier and neater.
- Durable Material: Typically made from powder-coated aluminum for corrosion resistance and outdoor durability, with stainless steel hardware included.
- External Joiner: Sits on the outside of the rail connection which can make alignment at complex angles simpler.
How It Works
- You insert the ends of two handrail sections into each side of the joiner.
- Adjust the angle of the joiner to match your desired direction change (e.g., around an outside corner or transition).
- Secure with the included fasteners so the joined rail sections stay firmly in place.
This flexibility is especially useful when installing an ADA-compliant secondary handrail around ramps, landings, or deck edges where the handrail path changes direction.
Where It Fits In Your Deck
- This piece is part of a larger RDI Aluminum ADA Secondary Hand Rail System, which also includes lineals, mounting brackets, straight joiners, end caps, and corner components — all designed to work together for a complete, code-compliant railing solution.
