Blum563H5330B 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)

These are highest quality slides I have used for years with no issues. They are easy to install and have never failed to work smoothly. The release mechanisms are large and easy to actuate for ease of drawer removal. They are very strong and I have no worries about anything I put in the drawers. I have used two high quality cabinet makers for projects and they both use these slides for their cabinets. These are well worth the price.

Blum undermount slides are awesomeThe packing in box was horrible. No separate packing for the delicate mount release hardware. Everything just tossed in one box.

High-End Quality for a Custom KitchenGot these at the request of my carpenter husband, who is building our kitchen cabinets. If you’re aiming for a high-end kitchen, these are the drawer slides to get—they’re the go-to choice for top cabinet makers. We’ve installed one drawer so far, and it looks fantastic and functions perfectly. My husband says they’re easy to install (though he does this professionally, so beginners might want to consult a YouTube tutorial). Highly recommend Blum for anyone who wants reliable, top-quality hardware with a great reputation. You won’t be disappointed!

Absolutely the best slides on the market. Supports drawer on the bottom and has a soft close feature. Perfect for kitchens, vans and dresser slides. Follow the instructions, install the slides and then build the drawers. Many videos on the web.

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.

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.

Everything arrived safe and all parts were accounted and in good working condition! Assembly of the slides were straight forward, however in my case some draw motivations were necessary to comply with installation specs. For those of you with slides that don’t seem to operate correctly….sticky, don’t soft close, ensure your slides are parallel to each other (so the draw slides are not binding). So far good product!

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