4. Installation
The MLYAYE Cellular Folding Door is designed for easy, no-drill installation. Follow these steps for proper mounting.
4.1 Measurement Guidelines
Accurate measurements are crucial for a proper fit. Determine whether you will be using an "Inside Mounting" or "Outdoor Mounting" method.
- Inside Mounting: Measure the width at the upper, middle, and lower points of the opening. Use the minimum of these three values for the width. Measure the height at the left, middle, and right points. Use the minimum of these three values for the height.
- Outdoor Mounting: Measure the desired width and height of the area to be covered. Ensure these measurements account for any necessary overlap or clearance.

Figure 2: Visual guide for measuring door openings for both inside and outdoor mounting. Inside mounting requires measuring width and height at multiple points and using the minimum value. Outdoor mounting involves measuring the desired coverage area.
Note: For custom sizes, ensure your measurements are precise before ordering.
4.2 Installation Steps (General)
While specific hardware may vary, the general no-drill installation process involves:
- Prepare the Opening: Ensure the surface where the door will be mounted is clean, dry, and free of obstructions.
- Attach Mounting Brackets: Secure the provided mounting brackets to the top of the door frame or wall, according to your chosen mounting method (inside or outdoor). These brackets are designed for tool-free attachment.
- Insert the Door: Carefully slide the top rail of the folding door into the installed mounting brackets.
- Secure the Sides: Ensure the side frames are properly aligned and secured, if applicable, to prevent movement.
- Test Operation: Gently pull and push the door to ensure smooth sliding and proper folding.
For detailed visual instructions, refer to any included diagrams or manufacturer's online resources.
