As supplied with our Fret Press System. This versatile wooden support caul is approximately 12" x 2-3/4" x 1", with a cork-lined channel for a guitar neck. It's an excellent support for pressing or hammering frets, or a lower clamping caul for regluing a fingerboard. You can also saw it into shorter lengths to make lower clamping cauls for "glue-in" fret jobs.
