Tongue & Groove 3/4" - 42

This embellishing 3/4" - 42 gap siding measures .750" in thickness, and the width can be machined to any required size within the moulder parameters used to mill the pattern. The profile is intentionally designed for blind nailing installation. It is comprised of a 1/4" tall by 19/32" wide offset groove and a 1/4" tall by 9/16" offset tongue with a .006" void in the joining area to ensure a nice fit when assembled. When two pieces of finished milled lumber are joined; they create a 5/16" wide by 5/16" deep channel between the merged boards. We offer a few other blind nailing designs with different sized channels for your review and consideration, t & g .750" - 78 with a 1/4" channel, t & g .750" - 16 with a 1/8" gap and t & g .750" - 49 with a 3/8" channel.
