About This Item

Save money with this set! Our 5 most popular sanding blocks for shaping a radiused fretboard and leveling installed frets. Just add sandpaper.

Accurately true or change a fingerboard's radius.
We make these hardwood blocks for use with Stikit Abrasives, to radius a fretboard quickly, accurately and without guesswork.

Shaping fingerboards: use 80 through 220-grit
Leveling frets: use 220 through 400-grit

Set includes the 5 most popular fretboard radii used in guitar building and repair:
7.25", 9.5", 10", 12", 16"

When working on compound radius fretboards, by simply changing blocks as you progress along the neck.

Dimensions: 8" (203.20mm) long x 2-3/4" (69.85mm) wide

See our shorter blocks for spot leveling, and for use as clamping cauls when gluing frets.

What's your radius?
Quickly find the curvature of a fingerboard or bridge with a set of radius gauges. Use them frequently to check your work as you smooth or shape a fingerboard or frets: a quick visual check keeps you from accidentally altering the shape—a mistake that's easy to make and hard to fix.

Super easy

(Customer's Reviews)

I think I may put a little finish on mine just to keep them smooth. Just used the 12" and it really helps keep the radius true.

Great quality, an essential part of any repair shop, very accurate.


Another quality tool.

(Customer's Reviews)

I purchased the complete set. Then I picked up a few extra of the ones I use the most. Being able to have different grades of paper mounted makes getting the final level a breeze.
