Q2: How labor-saving is the manual lifting operation? Is it easy to get stuck?
A2: The operation is very labor-saving, with a lifting force of only 4-8kg. The lifting mechanism adopts a slider and guide rail design, which runs smoothly and is not easy to get stuck; as long as the guide rail is kept clean, it can run stably for a long time.
Q3: What is the maximum span and height of the 70 Series window?
A3: The maximum span is 1.5-2.2 meters, and the maximum height is 2-3 meters, which can meet the needs of most ordinary small and medium-span spaces.
Q4: Can the 70 Series window be installed in high-rise buildings? Is it safe?
A4: Yes, it can be installed in high-rise buildings. Equipped with a reliable positioning device, anti-fall structure and patented balancer, it realizes arbitrary hovering of the window sash and will not slide down accidentally; the glass adopts tempered glass, which is safe and explosion-proof, meeting the safety requirements of high-rise buildings, and manual operation can also ensure use safety.
Q5: Can the 70 Series window be customized in terms of size and color?
