Chain Drive KS4 with DrehVolution

Premium solution for side-hung windows

The KS4 with DrehVolution gives the side-hung window stability in all positions and is universally adjustable for opening angles up to 70 degrees.

It requires only 26 mm of space on the frame. Installation is quick and simple, as the system uses one chain drive and the DrehVolution console, and it remains compatible with all AUMÜLLER locking drives.
