Tongue & Groove 5/8" - 7

This 5/8" - 7 v-groove siding measures .625" in thickness, and widths are adjustable and determined by the left vertical cutter head when milling. When two pieces of milled lumber are joined, they create a 3/8" wide by 1/8" deep v-shaped channel on the face side of the merged boards. The profile consists of a 13/64" tall by 9/32" deep tongue and groove with a 1/8" deep" by 3/16" wide angle on the face side edge of the pattern. There is also a .006" void area in the joint for expansion and contraction from seasonal changes in relative humidity.
