The WINSOON GCM5155 floor guide is designed for wall mounting and offers 8 different configurations to suit various door thicknesses and wall clearances. No drilling into the floor or grooving of the door is required.
Installation Steps:
- Determine Placement: Position the floor guide on the wall where the barn door will slide. Ensure it is aligned with the bottom edge of the door.
- Mark Drilling Points: Use the floor guide body as a template to mark the two drilling points on the wall.
- Drill Holes: Drill pilot holes at the marked points. Insert the plastic anchors if installing into drywall or masonry.
- Mount the Guide Body: Secure the floor guide body to the wall using the provided long or short bolts, depending on your wall material and desired depth.
- Select Roller Configuration: Choose one of the 8 assembly options based on your door's thickness and the desired distance from the wall. Refer to the "8 Different Assembly Methods" image for visual guidance.
- Assemble Rollers: Attach the big and/or small rollers to the floor guide body using the flange nuts and threaded hex jam nuts.

Operating Instructions
Once properly installed, the WINSOON GCM5155 Sliding Barn Door Floor Guide operates automatically to ensure smooth and stable movement of your barn door.
- Simply slide your barn door along its top track. The bottom edge of the door will pass between the rollers of the floor guide.
- The high-precision POM rollers will prevent the door from swinging out or wobbling, keeping it aligned with the wall.
- Ensure there are no obstructions in the path of the rollers or the door's bottom edge to maintain smooth operation.
Maintenance
Regular maintenance will ensure the longevity and optimal performance of your WINSOON GCM5155 Floor Guide.
- Cleaning: Periodically wipe down the floor guide body and rollers with a soft, damp cloth to remove dust and debris. Avoid abrasive cleaners.
- Lubrication: The POM rollers are designed for smooth operation. If you notice any stiffness or noise, a small amount of silicone-based lubricant can be applied to the roller axles.
- Check Fasteners: Every few months, inspect all bolts and nuts to ensure they remain tight. Re-tighten if necessary to prevent loosening over time.
- Inspect Rollers: Check the rollers for any signs of wear or damage. While designed for durability, extreme conditions or impacts could cause issues. Replace if significant wear is observed.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Door wobbles or swings | Rollers not adjusted correctly or loose fasteners. | Ensure rollers are snug against the door. Tighten all bolts and nuts. Re-adjust roller position if door thickness has changed. |
| Door movement is stiff or noisy | Debris on rollers or lack of lubrication. | Clean rollers and the area around them. Apply a small amount of silicone-based lubricant to the roller axles. |
| Floor guide feels loose on the wall | Mounting bolts are loose or anchors are compromised. | Tighten mounting bolts. If the issue persists, inspect plastic anchors and replace if damaged, or use stronger anchors suitable for your wall type. |
