Drawer slides are where a cabinet feels either expensive or cheap. The three things that matter are mounting style, extension, and load rating. Undermount slides hide completely beneath the drawer for a clean look and usually pair with soft-close; side-mount ball-bearing slides are easier to install, more forgiving of imperfect boxes, and carry more weight for pantry and tool drawers. Full-extension means the drawer pulls all the way out so you can reach the back, which matters most in deep base cabinets. We compare a premium undermount, a value full-extension side mount, and a workhorse commercial-grade side mount so you can match the slide to the drawer's job and how far you want it to open.
Blum's TANDEM plus BLUMOTION 563H is the gold-standard 21 in undermount slide: it hides fully under the drawer for a clean furniture look, carries 100 lb with buttery soft-close, and offers 4-way adjustment. But the required front locking devices aren't included, it demands a precisely built drawer box, and it costs far more than side-mounts.
- Heavy drawers
- Kitchen reno
- Soft close
- Hidden slides
Pros
- Slides hide completely under the drawer box, so you see clean wood sides and get the premium furniture look
- 100 lb rating plus buttery BLUMOTION soft-close handles loaded pot/utensil drawers without sag or slam
- 4-way adjustment lets you dial gaps and reveal perfectly after install — huge for face-frame reveals
Cons
- Front locking devices are required and NOT included — easy to forget and they add ~$3–4/pair
- Demands a precisely built drawer box (depth, notch for the hook) or it won't seat correctly
- Costs far more than side-mount slides, and length options are fixed — no field trimming
Liberty's D80622C is a 22 in side-mount, ball-bearing full-extension slide, the cheap, forgiving workhorse for shops, closets and budget kitchens. It glides smoothly and carries 100 lb. But the 1/2 in slide shows on each side, this base model has no soft-close (a pricier version adds it), and it needs exactly 1/2 in clearance per side.
- Budget drawers
- Workshop drawers
- Easy install
- Face frame cabinets
Pros
- Far cheaper and far more forgiving to install — mounts to the cabinet side and drawer side with basic clearance
- Ball bearings give smooth full extension and a solid 100 lb rating for tools or files
- Widely stocked at Home Depot in many lengths, so replacements/matches are always available
Cons
- The 1/2 in slide is visible on each side of the drawer — no hidden look
- This base model has no soft-close, so drawers can slam unless you buy the pricier 942205 version
- Needs exactly 1/2 in clearance per side; a too-tight or too-loose box causes binding or wobble
A workhorse commercial-grade side-mount slide rated 100 lb per pair, the Accuride 3832 is the go-to when a drawer has to carry real weight in tools, pantry goods, or files. It offers smooth full extension with a lever disconnect and hold-in detent, installs with standard 1/2 in side clearance, and trades the hidden look and soft-close of pricier slides for rugged, dependable value.
- Tool drawers
- Pantry drawers
- Workshop
Pros
- Classic commercial-grade ball-bearing slide with a proven 100 lb per-pair rating, ideal for heavy tool and pantry drawers
- Full extension with a lever disconnect and hold-in detent lets the drawer pull all the way out and resists roll-out or bounce-back
- Standard 1/2 in side clearance and 32 mm hole spacing make it a straightforward, forgiving install in shop and cabinet work
Cons
- Side-mount hardware is visible when the drawer is open, so it looks more utilitarian than a hidden undermount
- This base 3832 model is not soft-close (the 3832EC variant adds that at higher cost)
- Needs a precise 1/2 in gap on each side, so the drawer box must be built to size or it will bind or rattle

Frequently Asked Questions
- What is the difference between undermount and side-mount drawer slides?
- Undermount slides sit beneath the drawer and stay invisible when the drawer is open, giving a high-end furniture look, and they typically include soft-close. Side-mount ball-bearing slides screw to the sides of the drawer box, are easier to install and adjust, and generally handle heavier loads, which is why they are common for tool and pantry drawers.
- How do I measure for replacement drawer slides?
- Measure the depth of the drawer box from front to back and choose a slide length equal to or slightly shorter than that depth, in a standard even size such as 18, 20, or 22 inches. Also confirm the required side clearance, usually about 1/2 inch per side for ball-bearing slides, so the drawer clears the cabinet opening.
- What load rating do I need for a drawer slide?
- Most kitchen and dresser drawers are fine on a 75 to 100 lb per pair rating. For pantry, pots and pans, file, or tool drawers, step up to 100 lb or heavier ball-bearing slides. Remember the rating is per pair and drops as the drawer extends fully, so give yourself margin on heavy drawers.
