Tongue & Groove 3-1/4" - 11

This beautiful tongue & groove beadboard siding 3-1/4" - 11 measures 3.500" wide by .750" thickness, enabling the pattern to be milled from four quarter lumber. The attractive profile is composed of a 1/4" tall by 9/32" deep tongue & groove with a .010" void in the joint area for expansion and contraction during seasonal changes in relative humidity. The face of the detail retains a 2-5/8" wide flat area in the center, joined to a 1/8" wide by 9/32" deep sunk fillet attached to a 3/8" wide half round bead with another 1/8" flat line on the opposite side. When two pieces of milled lumber are joined together they create a 3-1/4" face coverage dimension with a 5/8" wide channel with a recessed half round circle in the center. We offer a couple of other similar profiles with different inner dimensions for your review and consideration, tongue & groove 3.250" - 12 and tongue & groove 5.250" - 2.
