The McMarker from McKay Bros. scribes accurate marks on sheet metal up to 12 inches. It allows users to mark seams, bends and allowances in just three steps. After selecting the depth and length on the tool, it is locked in place. The faceplate is then placed against the stock edge, and the scribe slides over to mark the measurement. The product is made out of a rust-resistant chrome and nickel finish, and also features a one-piece adjustable sleeve and faceplate, as well as a thumbscrew lock.
