Installation Guide
The DONGFXK motorized roller shades offer flexible installation options, including no-drill methods for convenience.
1. Measuring Your Window
Accurate measurements are crucial for a proper fit. Please refer to the diagram below for guidance on how to measure for both inside and outside mount installations.

Figure 3: Detailed instructions for measuring window width (W) and height (H) for both inside and outside mounts.
2. Mounting Options
Choose between an inside mount (within the window frame) or an outside mount (outside the window frame) based on your preference and window structure. For inside mount, the window frame depth must be at least 1.5 inches. For outside mount, consider adding 4 inches to the window width for optimal coverage.

3. No-Drill Installation Steps
For a hassle-free installation without drilling, follow these steps:
- Place the end of the shade unit with the no-drill device to the left side of the window frame.
- If there is a gap between the top rail and the window frame, use a silicone pad (included) to stick to the right side of the top rail, then push the right side of the smart blind into place.
- After installation, ensure you fasten the non-drill device securely.
