In this self-centering jig all four guide holes are threaded to accept screw-in drill bushings, so multiple side-by-side holes can be drilled without moving the jig. Holes can be spaced at 3/4", 1-1/4", 2" or 2-3/4" on center. Two each of 1/4", 5/16" & 3/8" bushings are provided. The jig clamps securely onto stock from 1/2" thick up to 2" inches thick.
