The sliding face gauge offers a quick and inexpensive way to install even rows of siding. When held against a course of siding, it creates the reveal for the next course, or a shelf for a shingle ledger. The sliding reveal loosens with two wing nuts and is fully adjustable between 1/8 inch and 9 inches. The thumb hook is easy to hold, and the tool also can be used for scribing a parallel line.
