I bought a Kreg cabinet handle jig and it worked great for my 4" handles, but my drawers had a wider spread so I made this enlarged version of the Jig.

It uses the angle and drill bushings from the purchased jig, so the new version is not functional by itself. You need to buy the Kreg jig and transfer the parts.

The design has notches set at 4" and 7.5", you may need to add more notches to suit your need.
