FAQs
Q1: What does "double lifting" mean for the 83 Series Manual Vertical Double Lifting Window?
A1: Double lifting refers to the independent lifting design of the upper and lower sashes. The upper and lower sashes can be lifted separately or at the same time, which is more flexible than single-sash lifting windows and can adjust the ventilation area arbitrarily.
Q2: Is the manual lifting operation labor-saving? Can the elderly and children operate it easily?
A2: Very labor-saving. The manual lifting mechanism adopts lever principle and precision bearings, with small lifting force, and the elderly and children can easily lift the window sash.
Q3: What is the maximum span and height of the 83 Series window?
A3: The maximum span is 1.5 meters, and the maximum height is 2 meters. The upper and lower sashes can be split according to the actual height, suitable for most ordinary spaces.
Q4: Can the window sash be fixed at any position? Will it slide down automatically?
A4: Yes, it is equipped with a multi-position positioning device and a patented balancer to realize the arbitrary hovering function of the window sash. It can be stably fixed at any lifting position and will not slide down automatically, which is safe and reliable. The desired angle can also be flexibly locked during manual adjustment.
Q5: Can the 83 Series window be customized in terms of size and glass type?
A5: Yes, full customization is supported. According to customer needs and on-site conditions, the size (span, height), window frame color and glass type (tempered glass, hollow glass, frosted glass, etc.) can be customized.
