Tongue & Groove 3-1/4" - 14

This 3-1/4" - 14 beadboard tongue & groove measures 3.500" wide by .375" thick. The profile is comprised of a 1/4" wide by 9/32" deep groove and a 1/8" tall by 1/4" wide tongue on the sides. There is .006" of voided space in the joint area to allow for expansion and contraction of the wood during seasonal changes in relative humidity. The face side consists of two recessed 1/4" wide half-round circles attached to a 1/8" wide chamfer on each side, with 1-1/8" broad lines in the center. When two pieces of milled lumber are joined together, they create 1/2" wide vee groove with two center beads, leaving an exposed face dimension of 3-1/4" wide.
