1. The system uses steel balls for positioning, realizing the locking and unlocking of the spring system, pulling down the lower beam to lower the roller blind, and releasing the system when it reaches the desired position unlocks and stops: if you need to continue descending, continue

Pull down the lower beam. (Note: If you need to recycle the fabric, first pull down the beam by 2-4cm and then release it. At this time, the system will unlock and the roller blind will automatically rise for recycling.);

2. The system is equipped with a built-in limiter, which generally sets the maximum height for the roller blind to automatically rise;

3. The system can choose mechanical and hydraulic retarders based on the temperature conditions of the environment in which they are used;

4. According to the square meter weight of the fabric, the width and height of the roller blind, different specifications of springs can be selected; According to the weight of the lower beam, different numbers of spring pre tightening coils can be set;

5. This system comes with a beam and adjustment mechanisms on both sides. The right self selling mechanism adjuster is used to adjust the upper limit distance of the system, and the left spring mechanism local adjuster is used for pre tightening the spring and safety

Fine tuning of spring elasticity after installation:

6. This system is particularly suitable for automatic upward spring roller shutter systems with a height of 2 meters that are expected to adjust the upward speed and upper limit position of the roller shutter on site after installation. If the height exceeds 2 meters, it may be operated
