Stop your file before the slot's too deep and your nut is ruined! This Safe Slot Nut Guard includes an 11-piece feeler gauge set.

Cutting string slots is delicate: if you cut one slot a little too low, you've blown the nut and have to start over. StewMac's own Don MacRostie devised the Safe Slot™ to make accurate nut slotting fast and fumble-free. He shows us how it's done in this video!

A trick the pros use:
Stack feeler gauges against the nut to set your slot depth. When the slotting saw touches the feeler gauges, you've hit your depth. The Safe Slot Nut Guard holds the feeler gauges tightly against the nut, and curved to the radius of your fingerboard. This leaves both your hands free to file. And you'll be able to work faster without worrying about cutting too deep.

  • Holds multiple feeler gauges
  • Pulls gauges tight to match fretboard radius
  • Locks in place against the nut. No slipping!

The pivoting caul adapts to most neck shapes, and the felt padding is guitar finish friendly. Use the clamp for any fingerboard up to 2-1/16" wide.

control your depth of cut??

After using this safe slot guard, one would wonder why you would try to proceed without it??? Super easy to use and greatly accurate. This will enable you to get the first fret to nut slot perfect, without the first fret string height perfect none of the rest of the fretboard will be correct. Save the grief get one!!!

Great Tool

Really does keep you from fumbling around trying to hold the feeler gauges at the right radius. A word of caution: add .020 (instead of Stew-Macs recommended .005 to .010) to the fret height and coax it into the right depth by hand after rough cutting the nut in with this tool. Like all tools, it takes getting used to using it.

One of the greatest tools ever

I used rubberbands in the past to do the same thing. Just to avoid moving and bouncing ot the gauges. I thought about making something similar to this tool. But then this great tool came out and I immediately ordered it. Well worth the price and a great helper. I like it. One word for customers from Germany. Normal feeler gauges here in Germany are not parallel in shape. They are more conical. So either order the gauges from Stewmac offered here or use piston clearance gauges (Kolbenspiellehre) if you need metric and inch.
