I am considering using the Bulm tandem slides so my dovetails are not covered. Drawers oare 23 deep by 30 wide. Anyone installed these and if so how hard were they to get right. Noticed a special jig and cutouts are necessary.

Blum doesn’t make a slide for a 23” deep drawer. They come 21’ and 24” The box has to be made to fit the drawer. 21” slide takes a 21” deep box, 24” slide takes a 24” deep box and so on. The side gaps are different to, 3/16” gap between the drawer box and the case, each side. 3/8” total for two sides. They require a1/2” space from the bottom of the box to the bottom of the drawer bottom. You will also need about 7/8” of space behind the drawer box for the slide to install correctly.

The are a great slide its all we ever use anymore.

Akdale, I commented on your blog, but I see here that you say your drawers are 23” deep. Les is right. Blum doesn’t make an undermount slide for a 23” drawer box. For a 24” Deep Cabinet, you need to make a drawer box that is 21” deep. The cut out on the back of the drawer is easy to do and the drilling jig for the hole in the back is not expensive. Hope we’ve answered most of your questions.

you can make your 23” guide work by moving the clips that mount to the bottom of the drawr back but only if you have the depth in the cabinet to do so as this also moves where you mount the drawer guide in the cabinet

Thanks bentlyj. I read somewhere the slides were not DIY friendly. Did not scare me off but just wanted to be sure it was not going to be a royal pain

Once you know the required diminsions they are a breeze. Make sure you check for the thickness of the drawer material too. 1/2” drawers require 5/8” off the width, and 5/8” requires 3/8” off the width I believe. Regardless to if I have those numbers swapped they are different. They can also accomodate 3/4” material, you just have to know how much to deduct from the opening. Good luck and make sure to post your project

What others have said: No need for the fancy jig, just measure and think a little bit and they’re pretty easy to get right.

Best slides on the market. IMO you can’t go wrong with any Blum products. If you are doing any number of drawers I do suggest their jig, or make your own, for drilling the proper hole in the rear of the drawer. The precision and diameter of this hole determine the adjustability of the drawer box. Pay a few dollars more and get the softclose slides.

As I recall I made my own jig. I also used the blumotion closers. Customer was extremely satisfied and the drawer operation is very impressive…but the cost is some what high. I would use them again if possible.

They have these slides with the Blumotion built in. Just be careful to follow the dimension advice in the Tandem catalog and everything will work fine. There is actually some allowance in the slides for slightly out of square or slightly mis-sized drawers but I would not push it. They are really great quality stuff. I do have the cheap drilling jig that lets you drill the holes for the pins into the drawer backs and the clips under the drawer fronts. Not necessary but they are convenient if you are doing a bunch of them. I also used these on a face frame cabinet and that makes it a little more complex. I like these slides a lot and would use any of Blum’s products.

The company I work for supplies the steel Blum uses and I can tell you that they spare no expence. Their matls are not cheap and they hold their suppliers to the highest standards. Hate to sound like a sales person but it’s just a darn good product.

Since people are raving about the Blum slides, I’ll toss in a bit here: I asked a question about drawer slides here on LumberJocks, and got some unexpected responses, which led to a longer piece on evaluating drawer slides, Blum, Accuride, and "cheap chinese knock-offs", with video of closing action, on my own web site.

Summary: There’s bits about the Accurides that I like better (I prefer their drawer removal mechanism), but the Blums were able to catch a big heavy drawer full of cast iron pots and close it softly.

Dan, I actually read your review and loked at your videos on you tube before posting here. Much appreciate the effort you went through. It does seem like the Blum corner has it. One thing I also notice in your write up though was the customer service at accuride was exceptional. I took the email address you provided and the rep got back to me in 1 day with great feedback.
