Safe Slot Nut Guard

About This Item

Stop your file before the slot's too deep and your nut is ruined!

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 the 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.

Set of 11 steel feeler gauges

Worth every penny

(Customer's Reviews)

This is one of those "why didn't I think of this" tools. A must have even for the non-luthiers who have to slut nuts every once in a while.
Saves lots of time and back and forth, precise.
Definitely a must!


Safe Slot Nut Guard

(Customer's Reviews)

Great idea and good for a safe start. Fret height is the true definer here. If thats not right (fret height definition too low) you got problems for the beginner. You would be wise in purchasing gauged nut saws to save file wear and breakage. Otherwise if you top the nut height right you won't have to go so deep with files. Well made as everything this company makes is. I'm still deciding on it. Don't get me wrong, Stew-mac is a guitar tech's heaven, I love tools and especially ones that speed-up work and raise quality. Thanks for the forum!


Amazingly simple

This tool makes the job so much easier.It takes the guess work out of how deep the slots should be. I highly recommend this tool! It's a must have!
