Privacy Rail Posts by RDI
What Privacy Rail Posts Are
RDI Privacy Rail Post / RDI Hideaway Privacy Rail Post are structural posts designed specifically to support RDI’s Privacy Rail™ system — an aluminum-framed outdoor railing that incorporates vinyl or decorative infill boards to create privacy screens on decks and patios. These posts serve as the anchor points for the rail frames and privacy panels.
Key Features
Material & Durability
- Made from powder-coated aluminum, offering excellent strength and resistance to weather and corrosion (tested over 10,000+ hours of salt-spray).
- Finish typically in Matte Black or White to match your railing system.
Types & Configurations
RDI Privacy Rail Posts are available in multiple styles and heights, so you can customize your railing installation:
- End Posts – used at the start or end of a privacy rail run.
- Mid (Line) Posts – sit between rail sections when you’re extending across a longer run.
- Corner Posts – for turning your rail at a 90° corner, bridging two directions.
-
Height Options:
42″ tall (for half-privacy panel applications)
72″ tall (for full-privacy sized panels)
Included Hardware & Accessories
Posts generally come with: pre-mounted base plates (for surface mounting), trim rings, infill adapter channels, hardware covers, and post caps — so they’re ready to install with the Privacy Rail kit.
How They Work
The posts are set at the ends and joins of a privacy railing section. Vinyl boards or decorative panels (sold separately) slide into the post’s adapter channels and lock securely using ClickConnect™ technology — a patented system that creates a tight, code-compliant fit with minimal visible gaps.

About this product…
These posts are used to bookmark our HideAway Privacy Rail, allowing for either a way to close out a look, or continue adding to it. Meaning, the MID posts have attachments on either end, allowing for our railing to continue on both ends of the post; the MID just acts as a marker in between the railing and panels. The END posts are a cohesive way to end railing or paneling, while the CORNER posts allow paneling and railing to conjoin at the corner and continue from there. Although there are two distinct heights offered, 42” and 72”, these posts can be manually cut down to achieve any desired height; super customizable and easy to work with. The 72” heights correspond to the “full privacy” option offered with our Privacy Rail Kit, while the 42” height correspond to our “half privacy” option. Designed to exceed both building code requirements, these structures ensure safety and long-term durability following your installation. Furthermore, the powder-coated aluminum posts were tested in harsh weather conditions, ensuring resistance from rust.
