This 1/8" radiused channel shiplap siding moulding 3/4" - 9 measures .750" thickness, widths are adjustable to any desired size within the limits of the moulder or shaper used to mill the boards. This pattern is typically used for siding on both interior and exterior applications. The rabbet dimensions are 1/2" wide by 3/8" tall on the face side and 3/8" wide by 3/8" tall on the back side. When two pieces of milled lumber are joined they will create a 1/8" wide gap with a 1/16" radius edge on the face side of the merged boards.
