Operating Instructions
Your WIN STELLAR bifold door is designed for smooth and quiet operation. To open the door, gently pull the knob towards you, allowing the panels to fold inward. To close, push the panels back into position until they are flat against the door frame.

The bifold design maximizes valuable space, making it ideal for areas where traditional swinging doors are impractical. The door glides effortlessly and is designed not to rattle.
Maintenance
Regular maintenance will ensure the longevity and smooth operation of your bifold door.
- Cleaning: Wipe the door panels with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals that could damage the paintable and water-resistant surface.
- Track Lubrication: Periodically apply a silicone-based lubricant to the top track to ensure smooth gliding of the rollers. Do not use oil-based lubricants, as they can attract dust and debris.
- Hardware Check: Annually inspect all screws, pivots, and hinges for tightness. Tighten any loose fasteners to prevent rattling or misalignment.
- Surface Care: The door surface is paintable. If you choose to paint it, use a high-quality interior paint suitable for engineered wood.
