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.

#3850 18" Precision Straightedge is part of our Basic Setup Kit.

For acoustic guitars, our Neck Set Gauge is designed to attach to the #3799 24" Precision Straightedge.

Excellent quality

After purchasing 24" straightedge I checked it with expensive, industrial straightedge - Stewmac`s one is dead straght, as expected. Superior quality, will long for lifetime.

What can you say about a straight edge?

This is a very high quality straight edge. It has a rust resistant finish and feels solid and dependable. Being a foot and half in length makes it perfect for guitar work. A very difficult to find length, in fact. I liked it so much, I bought two! Looks like it will last a lifetime.

Well made.

I own a few larger straightedges in 24" and 12" that I got elsewhere. I thought they were all that I needed. I realized I was wrong and really needed a 18" for the guitar. I looked elsewhere but couldn't find one with a tapered edge so I bit the bullet and bought this. The quality is great and it's perfect for what it does. It's made in the Good old USA too. A+

life is easy now

This piece of metal is lightweight and the tapered edge makes seeing the frets easier. I use the top side for some other jobs worth the money. If you need it, Stew Mac has it. Friendly service reps, fast shipping, and well packed: that is why I keep coming back.
