In excellent shape - very lightly used. See link below for additional details. Well over $200 new - asking $110 This drilling jig eliminates the time-consuming layout work usually associated with installing shelf supports. Rather than mark the location of every hole before drilling, you set the jig's rails at the desired inset from the edge, fix them in position with the thumbscrews on the clamp rods, and then drill. The jig guarantees that the holes will be exactly opposite each other and at equally spaced intervals. Twin-register pins positioned in the rails fit into holes you have already drilled, ensuring that the holes will continue to be accurately spaced. An entire upright can be accurately chain drilled with no chance of error and no need for detailed measuring.
