Preparing for Installation
Measuring the Door Opening
Accurate measurements are critical for a seamless fit. Measure the width, height, and depth of the door opening, taking into account wall thickness and flooring type. Double-check your measurements to avoid costly mistakes.
Planning the Layout
Decide on the door swing direction—whether it opens to the left or right—based on your space and preferences. Ensure proper spacing between the doors and the frame to allow for smooth operation without obstructions.
Step-by-Step Installation Process
Marking and Drilling Hinge Holes
Start by aligning the first door in the opening and marking the positions for the hinges. Drill pilot holes for the screws to prevent splitting the wood and ensure a secure fit.

Installing the Track System
Mount the top and bottom tracks securely to the frame, using a level to ensure they are perfectly aligned. Proper track installation is essential for smooth door movement.
Attaching the Doors to the Track
Connect the hinges to the doors and slide them into the tracks. Adjust the alignment to ensure the doors move freely without binding or dragging.
Testing and Final Adjustments
Once the doors are installed, test their movement to ensure they open and close smoothly. Make any necessary adjustments to the hinges or tracks for perfect alignment and balance.
Common Installation Mistakes to Avoid
Incorrect Measurements
Improper sizing can lead to gaps or uneven doors, compromising both functionality and appearance. Always double-check your measurements before cutting or installing.
Loose or Misaligned Tracks
If the tracks are not securely mounted or properly aligned, the doors may not operate smoothly. Use a level and ensure all screws are tightly fastened.
Over-Tightening Hinges
Over-tightening hinges can damage the doors or hardware, leading to alignment issues. Tighten screws just enough to hold the doors securely without causing stress.

Maintenance Tips for Bifold Doors
Regular Cleaning and Lubrication
Keep the hinges and tracks clean and lubricated to maintain smooth operation. Use a silicone-based lubricant for best results.
Adjusting Door Alignment Over Time
Over time, doors may shift or sag. Check the alignment periodically and make adjustments as needed to ensure they continue to function properly.
Handling Wear and Tear
Inspect the doors and hardware regularly for signs of wear. Replace damaged panels or hardware promptly to maintain the door’s functionality and appearance.
