4. Setup and Installation
Follow these step-by-step instructions for proper installation of your sliding barn door hardware. It is recommended to have two people for certain steps.
4.1 Important Installation Notes
- The hole spacer of the rail is 16 inches, which is suitable for standard wall studs.
- For walls with wood studs: Use the lag bolts. Do not drill pilot holes in step 2; instead, install the lag bolts directly in step 4.
- For concrete walls: Use the carriage bolts and anchors. Drill holes with a 3/8" drill bit to a depth of 1 9/16".
- Ensure the door panel width is at least 2 inches wider than the opening to ensure full coverage.
4.2 Installation Steps
- Prepare the Door: Attach the hangers to the top edge of your door panel. Ensure they are evenly spaced and securely tightened.
- Determine Track Position: Measure and mark the desired height for the track on your wall. Remember to account for the 6-inch clearance needed above the top of the door. The track should be level.
- Mark Drilling Points: Using the track as a template, mark the drilling points for the spacers. Ensure these points align with wall studs if applicable (refer to 4.1).
- Install Spacers and Track:
- For wood stud walls: Directly install the lag bolts through the track and spacers into the marked points on the studs.
- For concrete walls: Drill the marked holes (3/8" bit, 1 9/16" depth), insert the anchors, then secure the track with the carriage bolts.

- Install Anti-Jumpers: Attach the anti-jumpers to the top edge of the door, above the hangers. These prevent the door from lifting off the track.
- Hang the Door: Carefully lift the door and place the hanger wheels onto the installed track.
- Install Stoppers: Slide the stoppers onto the track at both ends. Adjust their position to control the door's travel distance and tighten them securely.
- Install Floor Guide: Position the floor guide on the floor directly below the door's path. Mark and drill holes, then secure the guide to prevent the door from swinging out.

6. Maintenance
Regular maintenance will ensure the longevity and smooth operation of your barn door hardware.
- Cleaning: Wipe down the track and hangers periodically with a soft, damp cloth to remove dust and debris. Avoid abrasive cleaners.
- Lubrication: If the door's movement becomes less smooth over time, apply a small amount of silicone-based lubricant to the track and wheel bearings. Do not use oil-based lubricants as they can attract dust.
- Fastener Check: Periodically check all screws and bolts to ensure they remain tight. Re-tighten if necessary.
- Stopper Adjustment: Ensure the stoppers are still firmly in place and effectively limiting the door's travel. Adjust if they have shifted.
