Step-by-Step Installation Guide:

Step 1: Measure and Prepare

Measure the Drawer Opening: Determine the width, depth, and height of the opening that will hold the drawers. This will help you choose the right drawer size and slides.

Cut cabinet: If you’re constructing your cabinet, cut them to the appropriate dimensions, making sure they fit the opening properly.

Step 2: Mark the Slide Position

Determine the Slide Position: Undermount slides are typically positioned about 1/4 inch above the bottom of the cabinet. The exact position can vary depending on the slide model.

Mark the Mounting Holes: Using a measuring tape and a square, mark where the slides will attach to the sides of the cabinet. Ensure that the marks are level and align with the slide height.

Step 3: Install the Drawer Slides on the Cabinet

Attach the Slides: Align the mounting plate of the slide with your marked line, ensuring that the front edge of the slide is flush with the front of the cabinet.

Secure the Slide: Use the screws that come with the slides to attach them to the sides of the cabinet. Make sure the slides are securely fastened, and do not over-tighten.

Check Alignment: Ensure that both slides are level and parallel with each other.

Step 4: Prepare the Cabinet to Receive the Cabinets

Install the Cabinet Rail: Undermount slides often have a separate rail that attaches to the cabinet. Install this rail according to the manufacturer’s instructions. This rail must be level and fixed in place to allow for smooth operation.

Mark for the Rail: Measure from the bottom of the cabinet to where the top of the slide rail will be. Use a level to ensure it’s straight.

Step 5: Install the Slide Rails in the Cabinet

Attach the Rail to Cabinet Sides: Align the rail on both sides of the cabinet and secure it using the provided screws. Make sure it is level and at the correct height above the bottom of the cabinet.

Step 6: Install the cabinet

Insert the Drawer: Carefully slide the drawer into the cabinet. Ensure that the slides engage properly with the rail on the cabinet.

Adjust the Fit: If the slides allow for adjustment, you can make minor tweaks to ensure the drawer opens and closes smoothly.

Step 7: Test the Operation

Test the Drawer: Open and close the drawer several times. Check for any sticking or misalignment and adjust as necessary.

Final Adjustments: Tighten any loose screws and ensure everything is secure.
