- Step 1: Measure Opening and Install Track
Measure the width of your door opening accurately. Securely install the top track (1) to the top of the door frame using appropriate fasteners. Ensure the track is level. - Step 2: Install Door Hardware
Attach the fixed door top pivot (2), active door guide pivot (3), and hinges (4) to the door panels as indicated in the detailed instructions. Install the bottom fixed bracket (6) and bottom fixed door pivot (7) to the bottom of the door frame. - Step 3: Fit Door into Track and Adjust
Carefully lift and insert the door panels into the top track and align with the bottom pivots. Adjust the pivots and guides to ensure the door hangs plumb and operates smoothly. Attach the knobs (5) to the door panels.

5. Operating Instructions
The SMARTSTANDARD Bifold Closet Door is designed for smooth, space-saving operation. To open the door, gently pull the knob on the leading panel. The panels will fold inward, allowing access to your closet or space. To close, push the leading panel back until the door is fully extended and aligned within the frame.
5.1 Space-Saving Design
Unlike traditional swing doors that require significant clearance, bifold doors fold neatly, maximizing usable floor and wall space. This makes them ideal for bedrooms, laundry rooms, pantries, and other areas where space is at a premium.

6. Maintenance
The SMARTSTANDARD Bifold Closet Door is constructed with a durable MDF core and a waterproof, scratch-resistant PVC surface, making it easy to maintain.
6.1 Cleaning
- Simply wipe the door panels clean with a soft, damp cloth.
- For stubborn marks, a mild, non-abrasive cleaner can be used. Avoid harsh chemicals or abrasive scrubbing pads, as these can damage the PVC surface.
- Regularly clean the top track to prevent dust and debris buildup, which can affect smooth operation.
6.2 General Care
- Periodically check all hardware (hinges, pivots, track) for tightness and wear. Tighten any loose screws.
- Lubricate the track and pivots with a silicone-based lubricant if the door operation becomes stiff or noisy.
- Avoid hanging heavy items on the door panels, as this can cause warping or damage to the hardware.

7. Troubleshooting
If you encounter issues with your bifold door, refer to the following common troubleshooting tips:
- Door not folding smoothly: Check the top track for debris or obstructions. Ensure the pivots and guides are properly lubricated and not damaged. Verify that the door panels are aligned correctly.
- Door not closing completely: Ensure the bottom pivot is correctly seated and the door is plumb. Check for any obstructions in the door's path.
- Door rubbing against frame: Adjust the top and bottom pivots to center the door within the opening. Ensure the door frame is square and level.
- Loose hardware: Periodically inspect all screws and fasteners and tighten them as needed.
