Details

Extended length for fast, precise shaping. Create a constant radius on an unfretted fingerboard, or level installed frets with this unique tool for the professional guitar shop.

The 18" long extruded aluminum block is comfortable to hold, and its stiffness and precisely machined radius assure accuracy that's not possible with a wooden block of the same length. We designed this tool for a lifetime of use in the busy shop.

Lifetime durability • Extended length
Fast, accurate fret leveling and fingerboard shaping


Dimensions: 18" long x 2-3/4" wide (457.2mm x 69.85mm)
Seven different radii are available, for popular fretboard shapes.

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 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.

Works on stainless frets, too!
All of our tools are suitable for use on stainless-steel fretwire, with the exception of our Fret Tang Nippers and Fret Cutters. Modern stainless-steel fretwire is known to be harder than the traditional nickel-silver blends, but our own shop experience indicates the wire does not cause premature wear of files or sandpapers.

I purchased one 16" radius sanding beam and I am pleased with the quality. I might have purchased a few more if they were not so expensive.

Cet outil est merveilleux car pour niveler soit les frets ou la touche d'une guitare il touche a toute la surface et on obtient un meilleur rTsultat et une touche bien droite ou un nivelage de frets bien droit, ces merveilleux.

Fast and Accurate

These are excellent tools if you are serious about the quality of repairs/production. The fretboard and frets are arguably the most important part of a guitar when it comes to playability and these beams make short work of getting that right. These are pricey, so the difficult part is choosing which radius beam will pay for itself the quickest. I settled on the 9.5" beam and plan to get more if the price comes down ;-)
