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.
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.
