Bottom groove opening from top to bottom | Familiar and stable operating method
"Bottom groove opening up and down" is the basic operating mode of traditional electric roller blinds. The curtain is lowered from the top or raised from the bottom. The operation is intuitive and easy to master.
This mode is particularly suitable for spaces that require quick adjustments to the overall level of shading, such as meeting rooms, bedrooms, or windows that receive all-day light, ensuring consistent and stable shading.

The top channel and bottom channel rise and fall synchronously , truly embodying the concept of free control.
In synchronous mode, the top opening and bottom groove can be opened or closed simultaneously, and can move up or down synchronously, allowing the entire curtain to move in the same proportion.
Users can freely adjust the shading position according to the angle of the light source at different times, precisely control the visual center of gravity and indoor brightness, and fully present the flexible and active shading concept of "Free Roll".

Top-mounted independent top and bottom opening | Targeted lighting while preserving privacy
With the "independent top and bottom opening" mode, the curtain can be pushed open from bottom to top to allow natural light from above to enter the room, while retaining the lower shaded area, thus balancing lighting and privacy.
This design is ideal for street-facing units, low-rise residential buildings, or office spaces, as it allows soft sunlight to enter while avoiding external visual interference, thus enhancing the comfort of the space.
