If you're staring at a pile of hardware and wondering where to start, these Salice undermount drawer slides installation instructions will help you get those drawers sliding like butter without losing your mind. There's something deeply satisfying about a drawer that closes itself with a quiet, high-end "whoosh," but getting there requires a bit of precision. Salice makes some of the best hardware in the business—specifically their Futura line—but if you've never put them in before, the math can feel a little intimidating. Don't worry, though; once you understand the logic behind the measurements, it's actually a pretty straightforward project.
Getting the drawer box right from the start
Before you even touch a screwdriver, you have to make sure your drawer box is actually built for undermount slides. This is where most people trip up. Unlike side-mount slides, which are pretty forgiving, undermounts require the drawer to be built to very specific dimensions.
For most Salice undermounts, you're looking at a maximum drawer side thickness of 5/8 inch (16mm). If you built your drawers out of 3/4-inch stock, you might run into clearance issues unless you "rabbit" the edges or use a specific slide model designed for thicker wood. The big thing to remember is the internal width of the drawer. You generally want the inside of your drawer to be about 42mm (roughly 1 21/32 inches) narrower than the cabinet opening.
Also, don't forget the "notch and bore." This is the hallmark of undermount slides. You need to cut a notch out of the back panel of the drawer so the slide can sit flush underneath. You'll also need to drill a small 6mm hole in the back of the drawer box. This hole is where the little "hook" on the back of the Salice slide grabs the drawer. If you forget this, your drawer will just slide right off the tracks when you pull it out.
Preparing the drawer for the locking devices
Once your box is built and notched, it's time to flip it over and install the locking devices. These are the plastic clips that sit at the front corners of the drawer bottom. They're the "brains" of the operation—they allow you to clip the drawer onto the tracks and provide the adjustment levers for later.
Line the clips up flush with the front and sides of the drawer box. It's usually a good idea to pre-drill your screw holes here. Since you're often screwing into the end grain of the drawer front or the edge of the plywood, it's really easy to split the wood if you just ram a screw in there. Use the screws that came with the clips, and make sure they're nice and tight. Once those are on, your drawer is ready to meet its new home.
Mounting the slides inside the cabinet
Now we move to the cabinet itself. This is where you'll need your level and a steady hand. If you're working with a frameless cabinet (European style), you'll be screwing the slides directly into the side walls. For face-frame cabinets, you'll likely need rear mounting brackets to support the back of the slide.
The most important measurement here is the setback. You don't want the slide to be perfectly flush with the front edge of the cabinet. Usually, you want the front of the slide to sit about 4mm (about 5/32 inch) back from the front edge for an overlay drawer. If you're doing inset drawers, you have to factor in the thickness of the drawer front so everything sits flush when closed.
Use a level to make sure the slides are perfectly horizontal. If one slide is even a tiny bit higher than the other, your drawer will sit crooked, and it might not close properly. I like to use a spacer block—a scrap piece of wood cut to the exact height I want the slides to sit—to hold the hardware in place while I drive the screws. It's a lot easier than trying to hold a heavy metal slide and a level at the same time.
Clicking the drawer into place
This is the moment of truth. To install the drawer, pull the slides all the way out until they're fully extended. Pick up your drawer box and set it onto the slides. You'll want to push it back until you hear two distinct "clicks." Those clicks are the locking devices at the front grabbing onto the slides.
Once it's clicked in, give it a few test slides. Don't be discouraged if it isn't perfectly aligned on the first try. One of the reasons professionals love Salice is the integrated adjustment system. If the drawer front looks a little tilted or isn't sitting flush with the cabinet, you don't have to take the whole thing apart.
Dialing in the adjustments
If you look at those plastic locking devices you installed earlier, you'll see some little thumbwheels or levers. Salice slides usually offer 6-way adjustment. This means you can move the drawer up and down, side to side, and even adjust the depth (how far in or out it sits).
- Height adjustment: Usually a lever or wheel that lifts the drawer box slightly. Use this if your drawer fronts are hitting each other or look uneven.
- Side-to-side: This helps center the drawer in the opening.
- Depth adjustment: Great for making sure the drawer front sits perfectly flush against the cabinet face.
Take your time with this part. Sometimes a tiny turn of a wheel makes a huge difference. It's much better to spend ten minutes fiddling with the adjustments than to live with a crooked drawer for the next ten years.
Some pro tips for a smoother install
If you're doing a whole kitchen's worth of these, get a jig. There are several universal undermount jigs on the market that help you mark your holes and set your setbacks perfectly every time. It saves a ton of measuring and cuts down on "oops" holes in your nice cabinets.
Another thing to watch out for is debris. Undermount slides are precision pieces of hardware. If you get sawdust or a stray screw inside the ball-bearing track, they're going to feel crunchy and gross. I usually give the slides a quick blast of compressed air before the final install just to make sure they're clean.
Lastly, make sure you're using the right screws. Most Salice kits come with #6 or #7 wood screws. Using a screw with a head that's too big can actually interfere with the slide's movement. Stick to the hardware provided, and if you lose a screw, try to find an exact match rather than just grabbing whatever is in your junk drawer.
Troubleshooting common issues
If the drawer won't "click" in, check the back of the drawer. Usually, the hole you drilled isn't deep enough or is slightly off-center, preventing the hook from engaging. Another common culprit is the notch—if it's not wide enough, the slide will bind against the wood before it can reach the locking device.
If the soft-close feature isn't working, check to see if the slide is level. If the back of the slide is higher than the front, the drawer is essentially trying to roll "uphill," which can fight against the soft-close mechanism. Leveling things out usually fixes the problem instantly.
Installing these isn't exactly a five-minute job, but once you follow these salice undermount drawer slides installation instructions, you'll see why people pay the premium for them. They turn a basic cabinet into something that feels truly custom and high-end. Just remember: measure twice, drill once, and don't forget to listen for that "click!"
