Blum 563H5330B 21" Tandem Drawer Slides Plus Blumotion Complete Kit. with Runners 563H, Locking Devices, Rear Mounting Brackets and Screws (for Face Frame Or Frameless Application), Zinc (Pack of 6)

Awesome slides. Read specs before you DIY anything for all sizes

Super good

These slides were ordered and installed on a cherry dresser that I made for my bedroom. There are a LOT cheaper options on the market, but none had the smooth action of these slides. They are a little fussy to figure out, and your drawer and opening measurements have to be near dead-on.However, once I understood how they are installed, I was able to put them in and adjust them to perfection.I used a side mount configuration with inset drawers. The slides have minor adjustments for front and rear drawer height, and as I set the gaps at about 3-4 playing cards thickness on the Top/Bottom, and 1-2 cards on the sides, I was able to dial everything in as required. I use playing cards to set even gaps on my drawers to ensure everything looks right and works well when done.The slides clip into the drawers easily, and have orange release levers under each side of the drawer so you can easily remove them for cleaning or to grab a wayward sock from the case.I will never go back to the flimsy side mount roller slides on one of my projects again, it is just too much work to create something and use crappy drawer slides. Take your time to plan the installation, and thoroughly read the instructions from the Blum Website. The 15', 18', and 21' designation on the part related to the DRAWER depth, not the cabinet depth. The cabinets must be about an inch +/- deeper to accommodate the rear of the slide. I used 15" slides in 18" overall depth cabinets.Included with the order was(6) sets of Drawer Slides - Right and Left(6) sets of drawer locking devices which screw into the bottom of the drawer(12) rear mounting brackets for use in a face frame applicationplenty of screws for mounting the slides and locking devices.The locking devices in this kit do NOT have the side to side adjustment, only the up/down, so your side to side measurements and mounting must be spot on. There are Blum slides with side to side adjustments, but these slides do not.The Blum instruction sheet provides measurement specs for a variety of installation applications, face frame, inset, and overlay applications. STUDY them carefully before you build your drawers and everything will go together well.Overall, I give these slides a 5 star rating, but they are a bit fussy to get dialed in, and they are very expensive compared to other slides.I initially tried a set of the cheap slides, but returned them because the pistons in several slides did not work well or at all.

Drawer glides are awesome and honestly the best experience I've had installing drawers so far. Be aware this set has no adjustability, just clicks together so as long as you build your drawers right you shouldn't have a problem. If you decide you need adjustability you can just buy those plastic clips for what seems to be relatively inexpensive. They're expensive but you won't be thinking about that 3 years from now when they're still doing great vs a cheap set that starts spitting ball bearings out prematurely.

Bought 6 of these.Back tab has a very weak weld, broke on two with not much force. Was able to re solder it back on using a solder gun and flux.Otherwise nice and smooth.

What can I say about Blum?Just a simple great product

Purchased six pairs - not all close all the way and these are not adjustable.
