Installation Guide
Pre-Installation Considerations
Before starting, ensure your door opening is suitable for a bypass system. The door panel width should be wider than half of the (opening + overlap space) to fully cover the opening. There will be an 8" to 12" overlap space as the two doors hang on a single rail.

Step-by-Step Installation
Follow these steps carefully for a successful installation. Professional instruction and customer service are available to assist with any problems.
- Mark Stud Locations: Identify and mark the stud locations on your wall above the door opening.
- Attach Header Board (if needed): If your wall studs do not align with the pre-drilled holes on the rail, or if your wall material requires additional support, attach a sturdy header board to the wall first.
- Install the Metal Track: Securely mount the two pieces of the metal track to the header board or directly to the wall studs using the provided wall spacers and bolts. Ensure the track is level.
- Install the Rollers: Attach the rollers (hangers) to the top edge of your barn doors. Ensure they are securely fastened.
- Mount the Anti-Jump Disks: Install the anti-jump disks on the top edge of the doors, above the rollers. These prevent the doors from lifting off the track.
- Mount the Stoppers: Install the door stoppers at the ends of the rail to prevent the doors from sliding too far.
- Mount the Door Guides: Install the floor guide on the floor directly below the door opening. This guide keeps the bottom of the doors aligned and prevents them from swinging out.
- Lift and Place the Door on the Track: Carefully lift each door and place its rollers onto the installed track. Adjust the door stoppers and floor guide as needed for smooth operation.

Operation
The bypass barn door system allows two doors to slide independently on a single track, enabling access to different sections of an opening without requiring large swing clearances. To open or close the doors, gently push or pull the door panel along the track. The rollers are designed for smooth and quiet movement.

Maintenance
Regular maintenance will ensure the longevity and smooth operation of your barn door hardware kit.
- Cleaning: Wipe down the metal track and rollers periodically with a soft, damp cloth to remove dust and debris. Avoid abrasive cleaners that could damage the finish.
- Lubrication: Apply a silicone-based lubricant to the roller wheels and track every 6-12 months, or as needed, to maintain smooth sliding.
- Check Fasteners: Periodically inspect all screws and bolts to ensure they remain tight. Tighten any loose fasteners to prevent sagging or misalignment of the doors.
- Inspect Rollers: Check the roller wheels for any signs of wear or damage. Replace worn components if necessary.
Troubleshooting
Here are some common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Doors are difficult to slide or make noise. | Dust/debris on track, lack of lubrication, loose rollers. | Clean the track, apply lubricant to rollers, tighten roller bolts. |
| Doors are not aligned or sag. | Loose wall mounts, improper header board installation, uneven track. | Check and tighten all wall mounting bolts. Ensure header board is securely fastened and level. Re-level the track if necessary. |
| Doors come off the track. | Anti-jump disks not installed or improperly adjusted. | Ensure anti-jump disks are installed correctly and are positioned to prevent the rollers from lifting off the track. |
| Gap between doors when closed. | Incorrect door panel width or stopper adjustment. | Verify door panel width meets specifications. Adjust door stoppers to allow for proper overlap and minimal gap. |
