Add Concealed Spline Joint

Use Spline Joints on square corner boards to connect panels together to form either longer boards or taller boards. The concealed spline joints help the individual boards to match up straight and gives a much more uniform look to the larger unit it creates.

Example on How to Order: If you want a 4' tall x 16' wide board purchase 2 of the square corner 4 x 8 boards and add 1 of the 4' spline joints.

If you want a board that is 8' tall x 8' wide purchase 2 of the square corner 4 x 8 boards and add 1 of the 8' Spline joints.
