Tongue & Groove 1-3/8" - 10

This 1-3/8" - 10 log cabin siding measures 1.375" wide; the width can be manufactured to any desired size within the parameters of the machinery used to mill the pattern. The functional profile is comprised of a 7/16" tall by 13/32" tapered groove with a 1/4" tall by 5/16" wide chamfered edge; the opposite side dimensions are 3/8" tall by 3/8" wide offset tongue also with a 1/4" tall by 5/16" wide beveled edge. When two pieces of milled lumber are joined together, they create a 5/8" wide by 1/4" deep v groove on the face side with a 3/64" wide gap on the backside; this gap will assure a tight fit on the face side of the merged boards.
