Fret Slot Depth Gauge

Before you try to put frets in, make sure the slots are deep enough!

Be sure your fretwire will fit! Don't wait until after you've installed a fret to discover the slot wasn't quite deep enough!

Dan Erlewine developed this remarkably handy "look-before-you-leap" gauge for quickly comparing the wire to the slot. Simply hold the flat edge against the fret tang, note the height of the tang against the reference lines, fit the appropriate curved edge into the slot, and compare the lines again.

The gauge is machined from .018" (.46mm) stainless steel for durability in the repair shop, and it fits into any fret slot. It's a big help for refret jobs (it fits bound fingerboards), for setting the depth stop on our adjustable fret slotting saw, and for setting the cutting height of our fret slotting table saw blade. The non-glare etched surface is easy to read, and the curved edges fit all popular radiused and flat fretboards.

Does the job

Nice item, though I thought it would be bigger, according to the pictures.

Inavaluable tool

One of our star performers in the workshop . Refrets are so much easier to do when you have a way to ensure the slots are all clear of debris. We have one on every workbench. Highly recommended.

Great tool for slot depth

The addition of more lines for the depth of the slot made this tool perfect.

Re-fret on a 1968 Fender "Fretless Wonder" Slide in Frets.

By D. Bennett from San Antonio, TX

Ever had to re-fret a fender neck that was 1968 or older? They slid the frets in from the side of the neck and not straight in. On top of that, the neck has the owner's name inlayed in Agate. The fret slots had to be deepened and the neck had a compound radius. I could not have done the is job without Depth Gauge. He also wanted Strat Frets. No way could I have done this project without Stew Mac.

Very unique tool at a great price. Used it to set my fret-slot wire depth on a recent LP style build and it worked great!!!

Pay attention to the picture size from product to guitar neck. It's very small but does exactly what it's supposed to do. Good investment.
