But, as with any home improvement project, proper installation is key to ensuring your drawers function correctly and last for years to come.
In this article, we’ll provide you with a step-by-step guide on how to install undermount drawer slides. We’ll cover everything from the tools and materials you’ll need to measuring and preparing your drawers, to installing the slides and attaching the drawers. Let’s dive in!
Tools and Materials Required

Before we get started, let’s first go over the tools and materials you’ll need for this project. You’ll need:
- Undermount drawer slides
- Screws
- Screwdriver
- Measuring tape
- Pencil
- Level
- Drill
- Jigsaw or handsaw
- Sandpaper
It’s important to note that the specific tools and materials you’ll need may vary depending on the type and brand of undermount drawer slides you purchase. Be sure to read the manufacturer’s instructions carefully and gather all necessary tools and materials before beginning the installation process.
When it comes to undermount drawer slides, there are two types to choose from: epoxy-coated slides and ball-bearing slides. Epoxy-coated slides are less expensive and easier to install, while ball-bearing slides offer smoother and quieter operation. Consider your budget and preferences when choosing which type of undermount drawer slides to purchase.
Now that you have all the necessary tools and materials, let’s move on to measuring and preparing your drawers.
Measuring and Preparing the Drawer
Measuring your drawers correctly is crucial to ensuring a proper fit for your undermount drawer slides. Here’s how to do it:
- Remove the existing drawer slides from your drawer.
- Measure the length and width of the inside of your drawer box.
- Subtract 1 inch from the width measurement to allow for clearance. This will be the length of your undermount drawer slides.
- Determine the height of your undermount drawer slides by measuring the distance from the bottom of your drawer box to the center of the drawer slide.
- Mark the location for your undermount drawer slides on the inside of your drawer box using a pencil and level.
- Using a jigsaw or handsaw, cut a notch in the back of your drawer box to allow for the slide to be installed.
- Sand the edges of the notch to remove any roughness.
With your drawer measured and prepared, you’re now ready to install your undermount drawer slides.
Installing the Slides
Now that your drawer is measured and prepared, it’s time to install your undermount drawer slides. Here are the steps to follow:
- Attach the drawer slide to the cabinet by screwing it into place with the screws provided. Be sure to use a level to ensure proper alignment.
- Repeat the process for the second drawer slide.
- Attach the drawer slide brackets to the drawer box using screws.
- Insert the drawer into the cabinet, making sure that the brackets on the drawer slide are fully engaged with the slides on the cabinet.
- Test the drawer to ensure it opens and closes smoothly.
Tips for Ensuring Proper Alignment and Functionality
Proper alignment and functionality are essential to ensuring your undermount drawer slides work correctly. Here are a few tips to keep in mind:
- Use a level to ensure that your slides are installed straight and level. This will prevent your drawers from sticking or rubbing against the cabinet when opening and closing.
- Be sure to use the correct screws and follow the manufacturer’s instructions for screw placement. Using the wrong screws or placing them in the wrong location can cause your slides to fail.
- Check for clearance between the drawer and the cabinet. If there isn’t enough clearance, your drawer won’t open or close properly.
- Test your drawer’s movement before installing the other drawers. This will give you an opportunity to make any adjustments before proceeding.
- Consider adding drawer stops or soft-close mechanisms to your undermount drawer slides for added safety and convenience.
With your undermount drawer slides installed and functioning correctly, your drawers will be a stylish and functional addition to your home. In the next section, we’ll cover how to attach your drawers to the slides.
Attaching the Drawer
Now that your undermount drawer slides are installed, it’s time to attach the drawer. Here’s how to do it:
- Line up the drawer’s wheels with the slide’s tracks.
- Push the drawer into the cabinet until the wheels click into place.
- Test the movement of the drawer. It should slide in and out smoothly and without any wobbling or sticking.
- Adjust the slides if necessary to ensure proper alignment and smooth operation.
