To install Blum's totally concealed drawer slides, each drawer box must be drilled with six precise holes. The Undermount Drilling Guide makes that process fast and easy. Just butt it up to the front corners to drill the smaller angled holes for the locking devices. Not only will the location be spot-on, but the holes will be angled to 15° and your bit won't wander. For the larger holes in the rear, just hook it over the notch. The end result is a drawer box that clicks perfectly into place on the slides, every time. Works with Blum Tandem Plus drawer slides.
