2.75″ wide. 20 radii. Three lengths.
A radius sanding block for setting the fretboard profile during a new build, restoring the radius during a refret, or leveling frets to the board's existing curve. Standard 2.75″ width fits regular six-string and most narrow-spec bass fretboards.

Very nice radius block, I ordered a size that is not available anywhere else and it is very high-quality. Looks like CNC.

I love these radius sanding blocks. Super lightweight and very rigid. I also like to use these to glue fretboards onto the neck.

Haven't used them yet but they look like they're going to work great. Well made!
