Standard K55-38 Hand-Powered Integrated Roller Shade System Innovative "Manual Push + Electric" Dual-Drive System, Supports Hovering at Any Position Manual Operation with Zero Resistance in Case of Power Failure (Patented Emergency Unlock Design)

1. The system achieves instant pulling, stopping, and precise positioning of the rolling shutter by precisely balancing the weight of the fabric, the weight of the lower beam, and the elasticity of the spring, combined with electric drive. Adopting lithium motor, rechargeable, achieving "zero
The "line" power supply is easy to install. Hand pushing/pulling down the beam or electric control can easily stop at any height and achieve smooth recovery.
2. Select spring specifications based on fabric weight, width (0.8m-3m), and height (≤ 2.5m); Set the number of pre tightening cycles as needed.
3. By adjusting the number of spring pre tightening turns and the weight of the lower beam (which can be weighted), the fabric flatness and tightening effect can be adjusted to ensure optimal balance in manual/electric mode.
4. The system comes standard with a beam cover and built-in adjustment mechanisms on both sides: the right self-locking adjuster sets the upward limit; The left spring adjuster is used for pre tightening and fine adjustment of elasticity.
Mainly used for indoor shading
