RDI Mounting Brackets for Endurance Railing
What Endurance Railing Mounting Brackets by RDI Are
RDI Endurance Railing Mounting Brackets are installation brackets designed for use with the Endurance Original Rail vinyl railing system. These brackets are what you use to attach the top and bottom rails to posts, walls, or structural surfaces — helping you secure the railing in place for both level decks and stair runs.
The Endurance railing system itself is reinforced with aluminum stiffeners and includes basic mounting brackets in standard kits, but additional or replacement brackets are sold separately for custom installations or if you need extra hardware. Mounting brackets for level, stair, or round column installation for the Endurance Original Rail line of railing. Can be used when cutting down larger sections.
What They Do
These mounting brackets do the heavy lifting in your railing install:
- Secure the rails to posts & surfaces: Brackets align and hold the top and bottom Endurance rails securely between posts or at structural points.
- Allow different angles of installation: Separate level (flat) and stair brackets adjust to deck layouts and stair angles.
- Make custom rail cuts easier: If you trim a longer rail to fit a specific span, extra brackets help create new secure endpoints.
- Provide a finished appearance: After installation, cover caps snap over fasteners for a clean look that matches the vinyl rail.
Endurance railing kits already include the basic mounting brackets you need for a standard run — but these separate options let you add brackets for special angles, stair applications, additional sections, or replacements.
