2. Safety Information

- Handle door panels with care to avoid injury or damage. They are heavy and require at least two people for safe handling.
- Keep small children and pets away from the installation area.
- Do not hang on the door or apply excessive force, as this may damage the door or hardware.
3. Components List
Verify that all components are present before beginning installation:
- Preassembled Door Panels (2 panels, each 17.75" W x 77.75" H x 0.85" T)
- Top Pivot
- Bottom Pivot
- Roller
- Knob
- Hinges (pre-attached to panels)
- Top Track with Fascia
- Installation Hardware (screws, anchors, etc.)
4. Setup and Installation
This bifold door is designed for 36" x 80.5" openings. The actual door panel height is 77.75 inches. The top track requires remaining 1-3/4 inches with an additional adjustable range of 3/4 inches. The lower jamb pivot requires 7/8 inches.
4.1 Pre-Installation Checks
- Measure your door opening carefully. Ensure it is within the recommended dimensions of 36" wide and 80.5" high.
- Inspect all components for any damage or missing parts.
- Gather necessary tools: measuring tape, level, drill, screwdriver, pencil.
4.2 Installation Steps
- Install Top Track: Secure the top track with the fascia into the top of the door frame. Ensure it is level and centered. The fascia helps ensure a perfect fit without gaps.
- Install Pivots: Install the top pivot into the pre-drilled hole on the top edge of the door panel. Install the bottom pivot into the floor or bottom jamb, ensuring it is vertically aligned with the top pivot. This vertical alignment is crucial for door stability and smooth sliding.
- Attach Roller: Insert the roller into the top edge of the door panel, near the pivot.
- Mount Door Panels: Carefully lift the door panels and engage the top pivot into the top track. Then, lower the bottom pivot into its receptacle. Engage the roller into the top track.
- Adjust and Secure: Adjust the pivots and roller to ensure the door hangs plumb and operates smoothly. Tighten all fasteners.
- Install Knob: Attach the knob to the pre-drilled hole on the door panel.

5. Operating Instructions
To open the bifold door, gently pull the knob towards you and slide the panels along the top track. The door will fold inward, maximizing your opening space. To close, push the panels back along the track until they meet and form a flat surface.

6. Maintenance

- Cleaning: Wipe the door panels with a soft, damp cloth to remove dust and dirt. Avoid abrasive cleaners or harsh chemicals that could damage the pine wood finish.
- Hardware: Periodically check all screws and fasteners for tightness. Lubricate the top track and pivots with a silicone-based lubricant if the door begins to stick or squeak.
- Finishing: The door is unfinished and paintable. You can apply paint, stain, or varnish to match your interior decor. Ensure the door is clean and dry before applying any finish.
