For most buyers, Blum Tandem Plus BLUMOTION Undermount Drawer Slides are the best undermount drawer slides because their built-in BLUMOTION system provides a controlled, soft close. This design keeps the hardware hidden beneath the drawer and helps prevent slamming, making it a strong choice for kitchen upgrades and custom cabinet work.
This guide is for homeowners replacing worn runners, cabinet installers, and woodworkers building new drawers. The key checks are drawer length and weight capacity, since each slide must fit the cabinet opening and support the load without binding. Installation also matters, especially if you want easy adjustment after mounting. The six picks below are ranked with clear reasons and honest drawbacks for each, so you can compare premium hardware with more affordable options before buying. Check the required drawer dimensions and mounting method first.

6 Top Undermount Drawer Slide Picks
These six drawer slide picks are ranked from solid value to the strongest overall option, counting down to the top pick.
6. Hitess Undermount Soft-Close Drawer Slides
Best for: Multi-drawer cabinet upgrades
The Hitess set includes six pairs of 21-inch undermount drawer slides, enough for six drawers. Each slide provides full extension, with a listed pull-out length of 519 mm. The 70-pound load rating suits heavier kitchen, bathroom, or workshop drawers. These slides fit drawer side panels that measure 5/8 inch thick, so check your cabinet dimensions before ordering.
Cold-rolled steel construction and a zinc-plated finish give the hardware a sturdy base with added rust resistance. Soft-close action helps drawers shut with less noise, while the steel-ball mechanism supports smoother movement. The package includes 12 adjusting locking devices, rear mounting brackets, screws, and instructions. At around $96 for the six-pair set, the cost works out to roughly $16 per drawer, before any price changes. Installation still requires accurate measurements and careful alignment, especially with undermount hardware.
Pros
- Six pairs cover six drawers in one purchase.
- Full extension reaches a 519 mm pull-out length.
- Soft-close action reduces slamming and operating noise.
Cons
- The slides only fit drawers with 5/8-inch-thick side panels.
- Installation requires precise positioning, and undermount slides can be less forgiving than side-mount designs.
5. 22 Inch Soft Close Bottom Mount Drawer Slides
Best for: Multi-drawer cabinet upgrades
This set includes six pairs of 22-inch, or 550mm, undermount drawer slides. Each pair uses full-extension, ball-bearing steel hardware and supports up to 100 pounds. The package also includes mounting screws, 3D locking devices, and installation instructions. At around $88, it costs more than buying a single pair, but the six-pair count suits kitchen, bathroom, or workshop cabinet projects.
The slides use zinc-plated, cold-rolled steel, which should help resist rust during normal indoor use. Their soft-close mechanism slows the drawer near the end of travel, reducing slamming noise. They are designed for bottom mounting, so the hardware stays mostly hidden when the drawer is open. The main fit requirement is the drawer box. Side panels cannot exceed 5/8 inch, or 16mm. Installation also requires careful alignment, since small errors can affect extension and closing.
Pros
- Six pairs cover multiple drawers in one purchase.
- Full extension provides access to the drawer’s rear area.
- Soft-close action reduces noise and hard closing.
Cons
- The 16mm side-panel limit rules out thicker drawer boxes.
- Undermount installation requires accurate measurements and alignment.
4. Blum Tandem Plus BLUMOTION Undermount Drawer Slides
Best for: DIY kitchen drawer upgrades
The Blum Tandem Plus BLUMOTION kit is a concealed, undermount slide system for wood drawers. This 21-inch model offers full extension, so the drawer opens far enough to reach items at the back. Each kit includes one left and one right runner, two locking devices, two rear mounting brackets, and screws. It works with both face-frame and frameless cabinets, making it suitable for kitchen, bathroom, and custom cabinetry projects. Expect to pay around $38, though prices can change.
Its strongest feature is the built-in BLUMOTION soft-close system. Drawers slow down near the end of travel and close with less noise and impact. The locking devices hold the drawer securely, while tool-free height and tilt adjustments help align the front after installation. That makes fine-tuning easier than with slides that need repeated screw changes. Still, this system fits best when the drawer box and cabinet dimensions match Blum’s requirements. Blum has operated as a family-owned company since 1952, and some products are made in the USA with domestic and European components.
Pros
- Full-extension travel provides access to the entire drawer interior.
- Integrated soft close reduces slamming and closing noise.
- Tool-free height and tilt adjustments simplify front alignment.
Cons
- The kit supports one drawer only, so each drawer needs its own set.
- Installation requires accurately built wood drawers and compatible cabinet clearances.
3. Blum Tandem Plus BLUMOTION Undermount Drawer Slides
Best for: Custom kitchen drawer upgrades
These Blum Tandem Plus BLUMOTION runners are concealed, steel undermount slides for wood drawers. Each 18-inch pair offers full-extension access, so the drawer contents remain reachable at the back. The system supports up to 100 pounds per drawer and fits both face-frame and frameless cabinets. Six kits are included, enough for six drawers. The package contains six left and six right locking devices, 12 rear mounting brackets, and screws.
The integrated soft-close mechanism slows each drawer before it shuts, reducing slams and cabinet wear. Tool-free height and tilt adjustments help align drawer fronts after installation, though accurate drawer construction still matters. These runners suit kitchen, bathroom, and custom cabinetry projects where hidden hardware creates a cleaner appearance. At around $164 for the six-kit package, the price works out to about $27 per drawer pair. Blum has operated as a family-owned company since 1952, and many products use domestic and European components.
Pros
- Full-extension travel exposes the rear of the drawer.
- A 100-pound capacity suits cookware, supplies, and heavier storage.
- Six complete kits include locking hardware, brackets, and screws.
Cons
- Installation requires compatible wood drawers built to the runner’s measurements.
- The 18-inch length may not fit deeper or shallower cabinet boxes.
2. Chibery Undermount Soft-Close Drawer Slides
Best for: Face-frame cabinet drawer upgrades
The Chibery kit includes six pairs of concealed undermount slides, with six left and six right rails. This version fits 21-inch drawers, while the line also comes in 12-, 15-, and 18-inch lengths. Galvanized steel construction supports up to 100 pounds per pair, according to the listed specifications. Full-extension travel lets the drawer open nearly all the way, while the hydraulic soft-close system helps prevent slamming.
Each kit includes rear mounting brackets, six 3D locking devices, mounting screws, and installation instructions. Elongated holes allow depth adjustments, and bottom-mount holes help secure the rails beneath each drawer. The hidden design keeps the hardware out of sight and leaves the cabinet interior looking cleaner. At around $139, this six-pair package costs less per drawer than buying smaller sets, but buyers should confirm drawer length and cabinet clearance first. Installation also requires careful alignment, especially when replacing existing side-mounted hardware.
Pros
- Six pairs cover six drawers in one purchase.
- Full extension provides access to items at the back.
- Soft-close hydraulics help reduce noise and drawer impact.
Cons
- The 21-inch version may not fit shorter drawers or cabinets.
- Undermount installation requires accurate measuring and alignment.
1. Blum Tandem Plus BLUMOTION Undermount Drawer Slides
Best for: Multi-drawer kitchen cabinet upgrades
This six-kit set is made for wood drawers that need hidden, full-extension hardware. Each kit includes one left and one right 21-inch runner, plus locking devices, rear brackets, and screws. Across the box, that means six pairs of slides, six left and six right locks, and 12 rear mounting brackets. The undermount design stays out of sight beneath each drawer, so the cabinet keeps a clean look while the drawer opens fully for easier access.
The integrated BLUMOTION mechanism slows the drawer before it closes, reducing slams and noise. Tool-free height and tilt adjustments help align drawer fronts after installation, though the cabinet and drawer still need accurate preparation. The slides work with both face-frame and frameless cabinets, which suits kitchen, bathroom, and custom cabinetry projects. At around $178, this is a sizable hardware purchase, but it covers six drawers instead of just one pair. Blum has operated as a family-owned company since 1952, and many products are made in the USA with domestic and European components. Buyers should confirm drawer dimensions and mounting requirements before ordering.
Pros
- Six complete pairs cover a multi-drawer cabinet project.
- Full extension exposes the drawer’s contents from front to back.
- Soft-close action protects cabinet parts and cuts closing noise.
Cons
- The roughly $178 cost is high for a single-drawer repair.
- Installation still requires precise drawer construction and cabinet measurements.
Buying Guide
The most important factor is compatibility with your cabinet and drawer box. Undermount hardware needs precise clearances, and a small mismatch can cause binding, uneven gaps, or a drawer that will not close.
- Drawer dimensions: Measure the box width, depth, and height, not just the cabinet opening. Many systems require about 1/2 inch of clearance on each side, but follow the manufacturer’s exact specification.
- Weight capacity: Match the rating to the loaded drawer. Choose slides rated for at least 75 pounds for kitchen drawers, or 100 pounds or more for cookware, tools, or pantry storage.
- Slide length: Select a slide close to the drawer box depth. Common sizes run from 12 to 22 inches. A 21-inch slide usually suits a drawer box about 21 inches deep.
- Extension and closing action: Full-extension models expose the entire drawer interior. Soft-close versions reduce slamming, while push-to-open hardware suits handle-free cabinets.
- Adjustment and installation: Look for three-way adjustment, included locking clips, and clear instructions. A two-slide pack should include mounting screws; installation jigs often cost $15 to $40 and can improve alignment.
If you cannot have everything, prioritize exact fit and adequate weight capacity over soft-close features or lower price.
Frequently Asked Questions
How do I choose the right undermount drawer slides?
Choose undermount drawer slides by matching their length, load rating, cabinet clearance, and mounting system to your drawer. For example, a 21-inch drawer usually needs 21-inch slides, but confirm the manufacturer’s sizing chart before ordering. Soft-close models also require compatible drawer boxes and enough space beneath each drawer.
What size undermount slides do I need?
The correct slide size usually matches the drawer’s inside depth, with enough rear clearance for the hardware. A 21-inch-deep drawer commonly takes 21-inch slides, while a 24-inch drawer may need 24-inch slides. Always check the product instructions, since some systems require a specific gap or shortened slide length.
Can I install concealed drawer slides on existing cabinets?
Yes, you can install concealed drawer slides on many existing cabinets if the drawer box and cabinet opening meet the hardware requirements. Most pairs need precise side gaps, a flat drawer bottom, and mounting clips. Rebuilding the drawer may be necessary when the current box lacks the required clearance.
Are soft-close undermount drawer slides worth it?
Yes, soft-close undermount slides are worth considering when quiet closing and smoother movement matter more than the lowest price. They typically cost more than basic runners, and installation requires careful alignment. A quality pair may support around 75 to 100 pounds, but confirm the listed rating for your drawer size.
Conclusion
Blum Tandem Plus BLUMOTION Undermount Drawer Slides are the top choice for homeowners and cabinet builders who want quiet soft-close action, smooth travel, and useful adjustment points in a quality drawer system. If your priority is a lower upfront cost or a simpler replacement, choose a compatible side-mount slide instead, since it may suit older cabinets and basic repair projects with fewer installation demands. Before buying, double-check the slide length, drawer depth, cabinet and drawer-box compatibility, weight requirements, quantity needed for each drawer, and current price, since some listings sell pairs while others list individual components. A careful fit check prevents wasted time and costly returns.
