BLUM 21 Inch Drawer Slide, Full Extension, Concealed, Undermount. 563H5330B with 100 Lbs. Weight Capacity and Soft Close for 5/8 inch Thick Drawers. (Pair)

These slides are serving my kitchen very well. Unfortunately, they were not the easiest to install; but there are two parts to that story. The first part is that the scenario I had on my hands with the non traditional drawer dimensions would have made installing any slides difficult. The second part is that these slides, despite the bad scenario, were relatively easy to install. I did have some trouble getting them to lock properly, but once adjusted to near perfection they did lock and work like a charm.

great product. Would buy again.

Drawer slides worked as expected. I purchased these to replace existing slides at my house, which I believed to be the same model. Upon installation, I realized that some of the specs had changed since the previous ones were installed (8 years ago). Though the slides worked fine, the soft close feature long expired. I ended up having to clearance openings on the drawer for the runners about 1/8" on each side (which wasn't a big deal) making the installation slightly more annoying. Overall, I'm very satisfied as I no longer need to hear my family slam the drawer whenever something is thrown away!

Well machined, self close feature is great, smooth operation under heavy load

I'm upgrading my kitchen drawers to soft close and try this out on two drawers and they work excellent. The first one took me about 90 minutes to figure it out.There was a little bit of a learning curve with the instructions. Second drawer took me less than thirty minutes. What a difference.

Heavy duty drawer glide. I have not installed them yet but expect that they be a good choice for my project. I am putting new drawers in existing kitchen cabinets.

Best drawer slides hands down. Yes there are many companies that make similar products but I’ve always ended up back at Blum

Very nice. Did the job

Great quality
