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.
