5. 설정 및 설치
This section guides you through the installation of the JUBEST bifold door hardware. Accurate measurements and careful execution are crucial for proper function.
5.1. 설치 전 점검
- 문 준비: Ensure your door panels are the correct width (15" each) and thickness (1-3/8" to 1-3/4"). If necessary, trim doors to achieve the desired finished height, accounting for the hardware (door height + 2-7/8").
- Opening Clearance: Verify sufficient clearance for door swing. The system requires adequate space for the doors to fold and open without obstruction.
- Track Customization: The 60" aluminum track can be cut to a shorter length if required for your specific opening. Use appropriate tools for a clean cut.
5.2. 단계별 설치
- Install Pivot Plates on Door Panels:
Attach the top and bottom pivot plates to the door panels as shown in the diagram. Ensure the tabs on the pivot plates open towards the rear of the door opening. Use a 1/8" (3mm) pilot hole for screws to prevent stripping, especially in harder wood. Be precise with measurements (e.g., 15/32" or 3/4" from the edge) to ensure proper alignment.

- 경첩을 부착하세요:
Connect the door panels using the provided panel hinges. Ensure hinges are installed securely and allow for smooth folding action. For a 4-door setup, you will connect two pairs of doors.
- Install 3-Wheel Ball-Bearing Hangers:
Mount the 3-wheel ball-bearing hangers to the top edge of the appropriate door panels. These hangers are designed to distribute door weight evenly and ensure smooth, quiet operation within the track.

- Mount Aluminum Track:
Secure the aluminum track to the top of your door frame or header. The precision extruded box track protects against dust and dirt, ensuring flexible and free rolling. Use appropriate fasteners for your wall material. Ensure the track is level and securely mounted.

- 문 걸기:
Carefully lift and insert the top pivot pin into the wide hole of the track, then slide it into the smaller slot. Simultaneously, engage the bottom pivot pin into the floor-mounted pivot bracket. Push the plastic flange to secure the top pin. This step may require angling the door panels. Adjust the top and bottom pivot points after installation to achieve optimal alignment and smooth action.
- Install Track Stops and Panel Aligners:
Position and secure the track stops at the ends of the track to prevent doors from over-traveling. Install panel aligners (for 4-door sets) to ensure panels remain properly aligned when closed.
- 문손잡이를 부착하세요:
Install the door knobs onto the appropriate door panels for easy opening and closing.
- 최종 조정:
Once all doors are hung, make final adjustments to the top and bottom pivot points to ensure the doors are plumb, level, and operate smoothly without binding. Lubricate the top track with white grease for enhanced performance.
6. 사용 설명서
To open the bifold doors, gently pull the door knob. The panels will fold inward and slide along the top track. To close, push the door panels back into position until they are fully extended and aligned. The 3-wheel ball-bearing hangers ensure a smooth and quiet operation.

7. 유지관리
- 청소: Wipe the aluminum track and hardware components with a soft, damp 먼지와 이물질을 제거하는 데 천을 사용하십시오. 마감재를 손상시킬 수 있는 연마성 세척제 사용은 피하십시오.
- 매끄럽게 하기: Periodically apply a small amount of white lithium grease or silicone spray to the top track and the ball bearings of the hangers to ensure continued smooth operation.
- 점검: Regularly check all screws and fasteners to ensure they are tight. Over time, vibrations from door use can loosen connections. Inspect hinges and pivot points for wear and tear.
8. 문제 해결
| 문제 | 가능한 원인 | 해결책 |
|---|---|---|
| Doors do not slide smoothly or bind. | Track is dirty, hangers need lubrication, or doors are misaligned. | Clean the track, apply lubricant to hangers and track. Adjust top and bottom pivot points to correct alignment. |
| 문이 완전히 닫히지 않거나 틈이 생깁니다. | Misalignment of pivot points or track stops. | Adjust the top and bottom pivot points to ensure doors are plumb and meet correctly. Verify track stops are correctly positioned. |
| Screws strip out during installation. | Pilot holes too small or excessive torque applied. | Ensure pilot holes are the correct size (1/8" or 3mm). Use a hand screwdriver or a drill with a clutch set to a low torque setting. Replace stripped screws with higher quality alternatives if necessary. |
| Lower pivot pin comes loose. | Improper seating or insufficient securing. | Re-seat the lower pivot pin firmly. Ensure any locking mechanisms are engaged. If the metal is deformed, it may need to be reshaped or the part replaced. |
