3. Setup and Installation
This bifold barn door requires assembly and installation. It is highly recommended that two people perform the installation due to the weight and size of the components. A header board is not included and may be required for proper installation.
Important Installation Considerations:
- Door Width: The door width should be the opening width plus 2 inches for proper coverage.
- Wall Anchoring: Do not use plastic drywall anchors for securing the main rail. The weight of the door system requires attachment to wall studs or a sufficiently thick backer board. If the rail holes do not align with studs, install a sturdy wooden header board across the opening and attach the rail to it.
- Door Panel Assembly: Each door panel consists of multiple pieces (approximately 11 pieces per panel, excluding hardware) that require assembly before track installation.
General Installation Steps (Refer to included detailed diagrams for specific instructions):
- Assemble the individual door panels according to the provided diagrams.
- Determine the desired opening direction (right-to-left or left-to-right) and attach the fixed and sliding rollers accordingly.
- Install the main track rail above the door opening, ensuring it is level and securely fastened to wall studs or a robust header board.
- Attach the hanging wheels to the top of the assembled door panels.
- Hang the door panels onto the track.
- Install floor guides and door handle.

4. Operating Instructions
The FINOSEN Bifold Barn Door operates by folding inward as it slides along the track, allowing for efficient use of space. To open the door, gently push the door panel towards the side, allowing it to fold and slide along the track. To close, pull the door panel back into position until it fully extends across the opening.
5. Maintenance
The FINOSEN Bifold Barn Door is designed for low maintenance, featuring a durable PVC surface.
Cleaning:
- Wipe the PVC surface with a soft, damp cloth.
- For stubborn marks, use a mild, non-abrasive cleaner. Avoid harsh chemicals or abrasive materials that could damage the surface.
- The PVC surface is waterproof, allowing for easy cleaning without concern for moisture damage.
Hardware Care:
- Periodically check all screws and fasteners to ensure they are tight.
- Keep the track clean from dust and debris to ensure smooth operation of the rollers.

6. Troubleshooting
Common Issues and Solutions:
- Difficulty during assembly: The door panels arrive in multiple pieces. Carefully follow the assembly diagrams provided with the product. Having a second person assist with assembly and installation is highly recommended.
- Door does not slide smoothly: Check the track for any obstructions (dust, debris). Ensure all rollers are properly aligned and lubricated if necessary. Verify that the track is level.
- Door feels unstable or sags: Re-check all mounting screws for the track and ensure they are securely fastened into wall studs or a robust header board. Plastic drywall anchors are insufficient for this product.
- Door does not close completely: Check for any obstructions in the door's path or issues with the floor guides. Ensure the door panels are correctly assembled and aligned.
