Use these 4-inch long structural aluminum splines to join together two or more lengths of a handrail along a straight run to create a structural joint.
Joints using the structural aluminum spline do not need to be supported over a post! This allows you to join pieces of handrail to form one continuous run without needing to worry about the placement of your structural support posts.
In combination with our reinforced aluminum handrail, these splines allow you to extend your structural post spacing 7-9 feet apart with minimal deflection under load.
Aluminum splines are machined from heavy-duty type 6061 aluminum. This spline should be used on straight connection points anywhere railing exceeds 93 inches.
