CONWAY CLEVELAND LUMBER RULE 4-LINE 1" X 36" 400N
The Conway-Cleveland lumber scaling rules are used to measure the board feet content of sawn lumber. They are the product of many years of experience. Through constant improvement, they have come to be preferred by nearly all lumber inspectors everywhere.
With flexible shafts still hand-crafted from the finest split hickory money can buy, these rules have a special quality due in large part to the meticulous care we take in the selection of our raw materials.
