Undermount drawer slides mount under your drawer box instead of on the sides. This keeps all the hardware hidden from view. Your kitchen looks cleaner and more expensive. Regular side-mount slides show ugly metal tracks on both sides.
Undermount drawer slides solve this problem completely. They also work much better than old-style slides. Heavy drawers open smoothly without sticking or binding. Kitchen contractors prefer them because they handle daily use without breaking down.
Undermount drawer slides support more weight than side-mount versions. You can load them with heavy pots and dishes safely.
These slides bolt directly to your drawer bottom. The track mechanism stays completely hidden inside the cabinet box. All you see is the drawer face when you pull the drawer closed. This gives a floating effect that shouts designer looks.
Undermount drawer slides rely on precision ball bearings for movement. Tiny steel balls roll inside machined tracks. This makes even loaded drawers feel weightless when you pull them open. The engineering is simple but effective.
Two slides carry the entire drawer load. They distribute weight evenly across the drawer bottom. This prevents corner sagging that ruins drawer alignment. The mounting points spread stress over a wide area.
Most quality undermount drawer slides extend fully. This means you can reach items stored in the very back. Side-mount slides often only extend three-quarters of the way. You end up digging around for things you can't see.
No visible hardware creates ultra-clean lines. The drawer front becomes the only thing you notice. Your kitchen instantly looks more professional and modern. Guests will think you spent way more money than you did.
Quality undermount drawer slides glide like silk. Ball-bearing systems eliminate friction almost completely. Opening heavy drawers feels the same as opening empty ones. Your hands and wrists will thank you during busy cooking sessions.
These slides don't steal space from your drawer interior. Side-mount hardware eats up valuable storage room. Undermount drawer slides give you back every square inch. This matters most in smaller kitchens where space is precious.
Undermount drawer slides distribute weight better than any other design. They resist sagging even when fully loaded. Your drawers stay level and aligned for years. Cabinet doors won't get misaligned from the drawer weight.
Hidden mounting reduces wear on cabinet sides. Side-mount slides create stress points that crack over time. Undermount drawer slides protect your investment by reducing structural damage.

AOSITE undermount drawer slides hit the sweet spot for price and quality. I've used their professional series on several jobs. They handle 120 pounds without any problems.
The soft-close mechanism works smoothly every time. Installation is straightforward with clear markings on the slides. Most cabinet shops keep these in stock.
Their customer service answers the phone when you call. The slides come with solid mounting hardware, too.
Blum makes the best undermount drawer slides you can buy. I've used them in three kitchen jobs. They never break down.
The soft-close works perfectly every time. Your drawer shuts gently. No more slamming that wakes up the kids.
Salice undermount drawer slides cost less than Blum. They still work great, though. Installation instructions are super clear.
The company stands behind its product. A ten-year warranty covers everything. Most people never have problems with them.
The grass slides open smoothly. They use precision ball bearings everywhere. Your drawer extends out, too.
Takes about 30 minutes to install each drawer. Easy adjustment screws help you get it perfect. High-end cabinet shops love these slides.
Undermount drawer slides demand exact measurements for proper function. Measure drawer width, depth, and height carefully. Check the cabinet opening dimensions too. Each manufacturer has specific clearance requirements.
Write down all measurements before ordering slides. Double-check everything before drilling holes. Small measurement errors create major alignment problems later. Take your time during this step.
Undermount drawer slides include properly sized mounting screws. Generic hardware store screws often fail under load. Manufacturer screws have the correct thread pitch and length. They also use proper steel grades for strength.
Pre-drill pilot holes to prevent wood splitting. This step is critical with hardwood drawer construction. Make sure to use a drilling bit that is just a bit smaller than the diameter of the screws. Clean out wood shavings before installing screws.
Complete one drawer installation before moving to the others—test operation through the full extension range. Check alignment with the cabinet face frame. Make adjustments before installing the remaining drawers.
Make sure that the drawer face overhangs at exactly the length of the cabinet opening. The vast majority of undermount drawers and sliders have fine-tuned screws. Take time to get the first drawer perfect.
Misalignment causes most closing problems with undermount drawer slides. Check for sawdust buildup in track channels. Remove debris with the help of a vacuum or compressed air. Even small parts may also jam the mechanism.
Slightly loosen the mounting screws to adjust the drawer position. Sometimes the drawer box sits at the wrong height or angle. Minor adjustments fix most alignment problems quickly.
Lack of lubrication creates rough movement in undermount drawer slides. Apply white lithium grease to all track surfaces. Never use oil-based lubricants, as these tend to accumulate grease and dirt.
Examine all mounting screws frequently to ensure they are not loose. Vibration can work screws loose gradually. Tighten carefully to avoid stripping threads. If lubrication doesn't help, the slides may need replacement.
Overloading exceeds slide weight capacity limits. Check manufacturer specifications for maximum load ratings. Remove excess weight if you've pushed beyond rated capacity.
Sagging can also indicate worn ball bearings or bent tracks. Replace undermount drawer slides with higher-capacity versions designed for your typical loads. Don't try to repair damaged slides.
