18-Inch Spline Stock
Delrin plastic 18” spline stock is intended to be cut down on-site and modified to create any non-standard, horizontal transition, e.g. a 45-degree turn in your railing. Use a miter saw and deck screws as needed. One 18-inch stick is sufficient material to make up to 3 splines. Any custom Delrin spline should be supported by a structural post. Use 2-1/2-inch #9 decking screws to connect spline pieces.
Aluminum Handrail Splines are also available in:
All aluminum splines are machined from heavy-duty type 6061 aluminum. Use the #8 x 3/4" stainless steel sheet metal screws included with the spline to secure it through the underside of your handrail.
