Heavy sash – easy lifting
HS LiftUnit – Noticeably reduced operating force
Increasingly larger glass surfaces in lift and slide elements make operation more difficult, as the torque at the handle increases significantly and the door becomes harder to move. Our HS LiftUnit supports the carriage when lifting the active sash and reduces the torque at the handle by an impressive 50%. This noticeably increases your operating comfort.
