In refurbishing the kitchen, I’m replacing the old boxes with new, dovetail boxes that I built to 24” depth. However in placing the 24” Hettich undercount glides, I find that they miss by about 5/8” as the prong is supposed to fit into the hole drilled in the box back. As you can see, the slide is all the way forward preventing the prong from seating. Anyone run into this before and what was your solution. Thanks for any help.  photo image_zpsvya5wud9.jpg

If I understand your problem, why not just glue some small pieces of 3/8” plywood on drawer back in the 2 spots on either side where holes are needed and then drill holes.

An excellent hack workaround but I’m still wondering why. Looking on YouTube, there are so many excellent videos re: Blum slides showing installs but barely anything for Hettich and nothing speaking to proper measuring for box construction for Hettich. I thought I’d do a quick video and so my question as to am8 doing something wrong or do boxes need to measured a different way. Thanks for the hack though.

Here is their technical catalog. Maybe it will help.

I’m switching to Blum sliders instead. They’re the same price and have 4-way adjustability as opposed to Hettish’s vertical-only adjustment. I’m doing 1/8” reveals and the 4-way adjustability will make getting exact clearances much easier. Fortunately, the drawer dimensioning is exactly the same.

Have your say...
