Review on Enhanced Blum Tandem Drawer Slide Template for 563 Series by Eric Webb

This is great for a hole that needs to be drilled in the back of the drawer to accommodate the rail. What this doesn't do are two holes that need to be drilled for the Blum drawer hardware that attaches to the front. You'll have to spend an extra $30 on bits to go the distance to drill those two little corner holes. This is madness. Blum should make a template so you can use a regular drill bit with a regular drill bit to drill holes. In this pose you need a long extension to get to these holes. Better to get the Rockler Jig it Undermount Drilling Guide. I prefer this Blum template for the back holes, but the template matches the two holes you need to attach the drawer hardware to the front much better.
