Undermount Slides
Undermount drawer slides hide beneath the box and pull it shut with a soft close motion, so the drawer front shows no hardware. We stock Blum Tandem plus Blumotion and Movento runners in the common cabinet depths, with the locking devices and rear mounting brackets that go with them.Undermount runners need a box built for them: full opening width, a notched back and a bottom groove at the right height. Pick the slide model on the custom drawer box and we cut the box to match. Installing for the first time? Read how to install undermount drawer slides.

What makes a slide undermount
An undermount slide mounts underneath the drawer box instead of on its sides, so the drawer shows clean wood with no hardware visible. A hook on the back of each runner engages a hole drilled behind a notch in the rear of the box, and a locking clip under the front corners holds the box down and lets it come off without tools. Soft close is built into nearly every current runner, including every model we stock.
The box an undermount slide needs
Most undermount runners share one width rule: inside drawer width equals the cabinet opening minus 42 mm (1 21/32 in), which puts the outside width at the opening minus 13/32 in with 5/8 in sides. The notch and hook hole differ by maker, so the box has to be cut to the exact model, not a generic undermount shape. The undermount drawer slide guide has the full table by brand, and the notched drawer boxes hub has a drawing for each one.
Blum or Würth
We stock two Blum platforms, Tandem plus BLUMOTION 563 and Movento, and Würth's PRO600 family. Blum's Movento runs a wider notch than Tandem and can also be set up with TIP-ON BLUMOTION push to open. Blum undermount drawer slides walks the two platforms model by model, with the lengths, load and box prep for each.
Load and length by model
Load is rated per pair and climbs by model: Tandem plus BLUMOTION 563 is 100 lb static, Movento 763 and 763H are 125 lb static, and the heavy duty Movento 769 is 170 lb static. Lengths run in whole inches only, since the box depth has to match the runner exactly: Tandem offers 9 to 21 in, Movento 763 and 763H run 12 to 21 in, and 769 extends the range to 18 through 30 in. The notch also differs by model, 35 mm (1 3/8 in) on Tandem against 50 mm (1 15/16 in) on Movento, so the box is cut to the exact runner, not a generic undermount shape.
Clips and brackets
No maker's clip fits another maker's runner. We press on the matching clip at the shop when you pick it in the configurator, and a face frame cabinet adds a rear mounting bracket so the runner reaches past the frame to the cabinet back.
Questions
Do undermount drawer slides come in soft close?
Yes, standard on nearly every current runner, including every Blum and Würth model we stock.
How much narrower is an undermount box than the opening?
Much less than a side mount box. Most runners deduct the opening minus 42 mm (1 21/32 in) inside, which is about 13/32 in off the outside width with 5/8 in sides, compared to 1 in on side mount.
Can I put undermount slides on an existing drawer box?
Rarely without a new box, since the box needs a specific width, a rear notch, a hook hole and a recessed bottom built for that exact runner.
Do Blum and Würth undermount clips interchange?
No. Each maker, and each platform within Blum, bores its own clip holes, so the box has to be cut for the specific model you are running.
Do you notch boxes for undermount brands you do not stock?
Yes. Choose the unlisted model option on the configurator and we match the notch and hook hole to the maker's published spec.
