This version of the closet rod jig features more robust plastic, fewer parts, and simpler design. Cheaper, stronger, just as effective.
It is designed around a specific 5mm self-centering bit for 32mm line-bored systems. If you have one of these and the collar on the tip is 3/8" diameter, it will work. If not, you should opt to order a jig with the bit included. Note that these also have built-in depth stops, eliminating the need for the drill bit collar from the last iteration.
