Concealed Spline Joint

Spline Joints are essential accessories used on square corner boards to seamlessly connect individual panels, creating much larger, more uniform display units, whether building a longer board or a taller board. The concealed nature of the spline joints ensures the individual boards match up perfectly straight, contributing to a professional, cohesive look for the expanded unit. For example, to create a 4 x 16 wide board, you would purchase two square corner 4 x 8 boards and one 4 spline joint; similarly, to achieve an 8 x 8 tall board, you would purchase two square corner 4 x 8 boards and one 8 spline joint.
