These 2-1/2"-wide grooved brass caul inserts fit our fret pressing tools and are designed for working with radiused or flat fretboards.
The milled groove on the bottom keeps each caul properly centered on the fret.
#4367 insert with 6"-radius holds down the fret ends for gluing — especially important on the tight 7-1/4" radius found on many Fenders.
Fret Press Inserts are designed to fit all of StewMac's fret pressing tools.
