Tandem Plus BLUMOTION 21" Undermount Drawer Slides Kit Full Extension | 6 Kits, Soft Close, Locking Devices, Rear Mounting Brackets and Screws Included, For Wood Drawers, 100lb Load Capacity, Steel

Pros: These Blum slides are worth the money, and this was a good deal on six of them. So much cooler than side-mount drawer slides. The slides are reasonably forgiving in terms of alignment. The action is smooth, and the self-close is a wonder of engineering design. I could stare at them closing all day.Unavoidable: As for installing the slides, cabinets are tight spaces, and it would help to be a Hobbit.Cons: The packaging used to send these was, ahem, minimal. Scarcely thicker than a shoebox. Six of these weigh about 40-50 lbs, so the box was nearly falling apart when it arrived. I would suggest a few extra pieces of cardboard.I mounted these directly to the 'floor' of the cabinet, and as such, I needed the #6 Truss head screws ...which did not come with the kit. A quick trip to the hardware store solved that, but it seems like an oversight. When I ordered a single pair of these slides from another vendor, it came with the truss head screws. It was a small disappointment in an otherwise good experience.

Better than the cheaper options

When my old drawer slides broke, I was hoping to find an exact match and I did. These took me 10 minutes to install and they were perfect. And they operate flawlessly.

The drawer slides are great (I've used them for years), but be aware if the order if fulfilled by JIS INC, you will have problems with customer service. One of the slides was damaged so I returned the package as that was my only option. JIS INC promptly placed an order on my behalf then cancelled the order saying I should have contacted them before Amazon. So the order is cancelled but no refund. We've repeated the complain / answer cycle several times. Now they are saying I am outside the 30 day period and they cannot issue a refund. They wrote that to me April 25, 2026. I placed the initial order April 13, 2026. They are ignoring math to deny the refund.

We got these for the cabinets we are building based on several YouTube woodworkers using them. They are very solid and made of good material. They fit great into the cabinets. The price is good for the quality of the product. Instructions are great (once you can make a man read them) they seem easy to adjust and close nicely. Highly recommend

These do NOT have the wheel adjustment on the bottom for side to side adjustments. If you want that, get the ones that are about 20 bucks more per set of 6. The labeling is pretty lazy, especially considering the same pictures are used for both.

Great quality, very smooth & pretty easy to install

Excellent drawer slides, easy closing slides make closing drawers easy
