This 1/8" channel tongue and groove moulding
3/8" measures .375" thickness, the width can be machined to any desired size within the parameters of the moulder or shaper used to mill the pattern. The profile is comprised of a 1/8" tall by 1/2" deep overlap tongue and groove flanked by 1/8" tall vertical lines, this offset pattern is perfect for areas of a room that require blind nailing during the installation process. When two milled pieces of lumber are merged together, they create a 1/8" wide by 1/8" deep channel/quirk on one face side of the joined boards. There is a .007" void in the joint area for expansion and contraction to accommodate seasonal changes in relative humidity. This knife design includes five degree draft angles to maintain the ability to sharpen the cutters without altering the profile, while prolonging the milling time between sharpening. We have a 5/8" thickness version of this profile for your review and consideration, tongue & groove .625"- 17.
