Truss Rod Inserts for Fretboard Radius Jig
Add precision and versatility to your builds with our Truss Rod Inserts, designed specifically for use with our Fretboard Radius Jig. These inserts lock the router base in a fixed, centered position—making it easy to rout clean, straight truss rod slots.
Note: The Fretboard Radius Jig is not included.
Important Compatibility Note:
If your current router base does not have the brass insert shown in the image below, you have an older version that is not compatible with these Truss Rod Inserts.
We’ve got you covered—just contact us after purchasing the inserts, and we’ll include a free updated router base with your order.
