Begin by measuring the height and width of the closet opening at the top, middle, and bottom to account for any slight irregularities. Record the smallest width and height to ensure the doors will fit snugly within the frame without forcing them into place.

Horizontal Measurement

Measure the width across the top, middle, and bottom of the frame. Use the smallest of these three measurements to determine the width of your door system, allowing for a 1/8 inch clearance on each side to ensure smooth operation.

Vertical Measurement

Measure the height from the top of the frame to the floor or the baseboard on three occasions. Subtract the thickness of the floor covering and the desired clearance from the floor to calculate the final door height.

Inspect the closet jamb to ensure it is sturdy and flat; shim any uneven areas to create a level surface for the doors to glide upon. A stable and level jamb is the foundation for ensuring the doors operate smoothly and remain aligned over time.

Position the top track above the opening, aligning it with the center of the head frame. Secure it tightly using a drill and screws, driving them into the wooden studs behind the drywall for maximum support and stability.

Step 4: Hanging the Doors

Carefully lift the first door onto the track, engaging the wheels into the hangers. Repeat this process for each subsequent door, ensuring they are aligned side-by-side and sit flush with one another at the edges.

Step 5: Leveling and Final Adjustments

Use your level to check that the doors are perfectly aligned vertically. Adjust the wheels or hinges as necessary to achieve a consistent gap between the doors and the frame, allowing for effortless sliding without binding.

Once the doors are level and glide smoothly, tighten all hardware and inspect the alignment one final time. This attention to detail ensures your mirror sliding closet doors operate seamlessly and provide a polished, high-end look to your space.
