Woodworking Experience:
And excellent product
It's an extravagance to be sure, unless you are installing a lot of them, since it's not cheap, but it is very accurate, easy to use and really does make quick work of a slide which has terrible installation instructions. So if you don't mind taking up space for a large jig that has no other use, it is worth getting (note with all the negatives I've given, I bought one, and would buy it again).

Must have
Works perfectly. No measuring or fusing with the slides. I build furniture for a living and time is money. It’s a must have.

The best way to mount Blum runners
I used these to mount Blum Runners. when I was ready to install replacement drawers I used this guide to mount the runners. it took less then 10 minutes per drawer to install both runners and square the drawer face.

Great jigs, easy to use, very accurate, save time
These jigs are perfect for exact alignment every time. They save time & mistakes. Paid for themselves on the first job. The magnets hold the heavy under mount slides no problem.

The undermount slide jig is great. Strong magnets, and accurate size to mount slides. I used it on several drawers. It's better on face frame cabinets because then one can clamp the jig.
The drilling guide works OK, but I sawed the end off with the big holes so I could drill those in my drill press to keep from breaking out for cheap particle board drawers. I also think the guide depth for the latch holes is too deep, but easily adjusted to get mounting screws to bite the drawer wood. Overall happy with product

Does this work with all undermount slides?
Frank R on May 16, 2017
Can this be used for mounting on inset drawers, since the need a larger setback?
Jeff T on Jan 26, 2018
BEST ANSWER: Yes, you can easily adjust setback by sliding the slide on the magnets.
Can this be used for Salice 7555 smoove guides?
Gus G on Jan 7, 2019
Can this jig be used with inset doors?
Beth P on Jan 20, 2019
BEST ANSWER: This is a drawer slide jig. It doesn’t work with doors at all. However, if you are building flush inset cabinets this will help you hold the slide while you screw it into the blocking that you have installed to keep the cabinet inside wall flush with the inside of the face frame. So Yes it works with inset drawers. Hope that helps
Why does this jig have a 2mm setback when the Blum slides call for a 3mm setback?
Nelson A on Aug 30, 2019
BEST ANSWER: Can't say for sure but I know from experience it's not that critical. I found varied mountings in my kitchen and bathrooms of 1mm that can be caused by grain strengths in the cabinet frame. Don't sweat it, the Blums have forgiveness in the install.
In the description of the Slide Jig it states “Integral stop precisely sets a 2mm setback”. Blum calls for a 3mm setback. Is this a typo or a design flaw?
Gary P on Mar 21, 2018
BEST ANSWER: Gary, According to Blum, the Tandem glides require 1/8" (or 3mm) setback. I'm not really sure the difference in 1 mm would matter but you could use some double-stick tape and a 1 mm piece of wood or plastic attached to the setback tab to make the setback 3mm. If you really want an accurate answer, you should contact Blum to see if this 1 mm would make any difference.
Will this work with Grass Dynapro undermount slides?
