Patio HST wing support requires a bit of effort resulting from the high weight of these products. Increased comfort of use of lift and sliding doors allows the use of a suitable piece of equipment, which is a power-assisted via-the-reassuch. The presence of this component makes it necessary to change the position of the handle use less force.
How does the power-assisted via-end drive work?
The gear for easy use of the lift and slide door sashes is equipped with a special mechanism. Its presence reduces the torque of the handle when lifting the sash. This allows you to use less force to operate the Patio HST wing.
