Portavant 150 is a real all-rounder when it comes to ceiling mounting – it can also be easily installed in a ceiling pocket, in front of a lintel or in suspended ceilings. Portavant 150 can be used for sash weights from 50kg to 100kg and includes as standard a cushioning and retraction system on both sides. The spring force with which the door is retracted after cushioning can be adjusted to the sash weight. This enables the smallest possible opening resistances. Portavant 150 is also suitable for single-track wooden sliding doors.
