BlumTandem Plus BLUMOTION Drawer Slides Complete Pair, with Runners 563H, Locking Devices, Rear Mounting Brackets and Screws (for face Frame or Frameless Application) 21 Inch

Great product. I am an amateur woodworker doing a custom project. These rails were super easy to install and adjust. Follow the instructions (available on the Blum website) and you cannot message up. The fit was perfect and soft close is great. They have a very smooth slide and soft close is great. Even with the heavy weight I have in the drawer.

easy to install, slide very smoothly, self close works.

My main concern with this product is the fact that two plastic adjustment tabs were broken from two different 21 inch bottom soft close slides. They were both for the left-hand side and so it basically rendered two of the five sets that I bought broken. I was able to make one work by adjusting it with some difficulty, but I’m waiting for Bloom to reply about the other because I really don’t like to have the defective adjustment tabs in there. They may need to be adjusted sometime in the future and it is a real pain with that tab broken off.I sent a message to the seller and they quickly replace the broken parts for me. Therefore, I am changing my review to five stars because everything else was fine.

Impressive and heavy duty. Full extension is great. Installation video could be simpler.

I recently built a filing cabinet, and let me tell you, these are hands down the best drawer slides I have ever used! Yes, they come with a higher price tag, but trust me, they’re worth every penny.Once you get the hang of the installation (a bit of a learning curve, but nothing major), it’s smooth sailing from there. The soft-close feature is an absolute game changer! No more slamming drawers or waking up the entire house with a sudden bang. Just a gentle glide into place, making me feel like I’m living in a high-end furniture store.These slides are sturdy and can hold a lot of weight, which is a must when you're filing all those important documents (or maybe just hiding the junk you don’t want to deal with). I will never order any other drawer slides again! If you're serious about your DIY projects, do yourself a favor and grab these. Your drawers will thank you!

There were no instructions included but I found online instructions which made them very easy to install.

I had two drawer slides (SIKAI) that were no longer working where I couldn't find replacement parts for since they were pretty old. Bought these to replace them and they worked really well. I ordered the 21inch slides since my old ones were the same length.The seller I bought from was JIS INC and it included everything as described: 2 runners, 2 locking devices, 2 rear mounting brackets, and all the necessary screws. Nice soft closing drawer slides and easy to install. I ended up being able to reuse the holes at the ends of the slides but had to screw new ones for the hole in the middle of the runner. The locking devices I had to screw in new holes for all of them and used my old locking device screws as I was worried the ones included with these were a bit long.

These drawer slides are greatSolid, weight bearing and smoothOpen and close with the slightest of touchesGet them!!
