Our take on the Tri-Beam 3 'n 1 Notched Straightedge & Precision Straightedge

The Tri-Beam 3 'n 1 is a triangular aluminum beam that serves as three straightedges in one. Two notched sides straddle the frets to read fretboard flatness and neck relief directly, and the third is a plain precision-ground edge for checking fret level before and after fretwork. It suits guitar techs and players doing their own fretwork who want one tool instead of separate notched and plain straightedges. The notched sides cover common Fender and Gibson/PRS scale lengths, so it replaces two scale-specific notched straightedges, though it does not cover every scale without repositioning a notch over the nut.

About the Tri-Beam 3 'n 1 Notched Straightedge & Precision Straightedge

The Tri-Beam combines three straightedges in one triangular aluminum beam. Two sides are notched to sit over the frets, so you can read the fretboard itself. The third side is a plain precision-ground edge for checking fret level before and after fretwork.

The beam is CNC-machined from 6063-T5 aluminum with a blue anodized finish and has a hang hole. It is used to check neck relief, fretboard flatness and fret level.

The F-25.5 side can also be used on 24" and 22.75" scale lengths by placing a different notch over the nut.

Questions and answers

What does the Tri-Beam 3 'n 1 do that a plain straightedge doesn't?

Can it work on 24" or 22.75" scale guitars?
Yes. The F-25.5 side can be used on those scales by placing a different notch over the nut.
