About This Listing

New look! New durable black finish for longer life

New length! 4.5 inch beam for more uses in a busy shop
Create a constant radius on an unfretted fingerboard, or level installed frets with this unique tool for the professional guitar shop.

The 4.5" long extruded aluminum block is comfortable to hold, and its stiffness and precisely machined radius ensure accuracy that's not possible with a wooden block of the same length. The shorter length is perfect for spot leveling, creating a compound radius, and making super strong clamping jigs. This length is perfect for creating fallaway on an acoustic guitar.

Lifetime durability
We designed this tool for a lifetime of use in the busy shop. These super strong aluminum beams are also less prone to twisting and wear compared to wooden blocks.

The black finish helps protect against corrosion and dirty hands in the shop. The bottom is precisely milled to radius, and unfinished so sandpaper will seat cleanly.

A great clamping caul for glue-in fret jobs!
"I use aluminum fretboard sanding blocks to hold and clamp the frets in place while the glue dries...A scrap of Neoprene on the bottom of the caul protects the frets from the texture of the machined surface, and serves as a cushion that conforms to the radius a little better, conforming to any slight variations in the fretboard."
—Excerpt from Erick Coleman's book Fret Work Step-By-Step

Cut and stick!
3M Stikit Gold Paper Self-adhesive Abrasives (not included) are the right width for our leveling and radius sanding tools. Attach 80 through 220-grits for radiusing and leveling the fingerboard, and 220 through 400-grits for leveling the frets.
