Internal Splines for Any Handrail Configuration

To join handrail sections or mount handrail to posts, create a custom spline using spline stock or use a fixed corner spline for any level 90-degree corner. If necessary, use a structural epoxy to permanently fix your Delrin splines inside the handrail. For more information, check out How to Install Stainless Steel handrail on Venture Series Posts

Fixed Corner Spline

The fixed corner spline is made from Delrin, weather and UV-resistant exterior-grade plastic, and is designed for use at any level, supported corner transition. All Delrin splines are slightly oversized by design and may require a rubber mallet or dead-blow hammer to set in place.

15-Inch Spline Stock

Delrin plastic spline stock is available in 15-inch sticks and is intended to be cut down on-site and modified to create custom splines. Use a miter saw and deck screws as needed. One 15-inch stick is sufficient material to make about 3 splines. Any custom Delrin spline should be supported by a structural post. Use Venture series handrail mounting screws to connect spline pieces.
