Cauls for Jaws2

Hammering frets over an unsupported acoustic guitar top is risky! Safely press the frets in with Jaws2.

Jaws2 features special soundhole cauls and a self-leveling upper caul that take the stress off the guitar top, so you can safely press the frets into place. Jaws2 is a great idea that was conceived by luthier Bryan Galloup and refined by master fretman Dan Erlewine. Jaws2 utilizes the same 2-1/2" radius brass inserts as our other Jaws tools.

Jaws2 is a professional fretting tool with a self-leveling upper caul that adjusts easily to any neck. It includes five interchangeable 2-1/2" brass inserts, grooved to fit over the fretwire crown. The inserts match popular fretwire radii: 7-1/4", 9-1/2", 12" and 16", and a special 6"-radius insert holds down the fret ends for gluing. Additional radii are available.

Three wooden lower cauls are included: a contoured soundhole caul to span the braces inside a Martin-style guitar, a flat caul you can custom shape to fit over other bracings, and a felt-lined radiused caul to protect the back of the neck. Each caul features an ingenious internal magnet that holds it on the clamp jaw, allowing fumble-free setup.
