18" Precision Straightedge

Our straightedges are made specifically for checking neck straightness and relief, evaluating truss rod adjustments, and pinpointing high or low frets. Four versatile lengths are available for working on any fretted instrument, from mandolins to guitars to basses.

The narrow beveled edge allows easy and accurate viewing of the gap between the edge and the surface being checked. Made of durable stainless steel with a satin finish for easy marking with a pencil, each straightedge is precision-machined for accuracy to ±.0015" per foot.

These straightedges are also ideal for laying out projects on wood or paper, and for setting up table saws, jointers and other shop equipment.
