Winkhaus GAK.2225-2 Multipoint Gearbox ActivPilot Concealed 2-Point Lock 1975?2225mm

Product Overview

The Winkhaus GAK.2225-2 multipoint gearbox is a concealed sash transmission component designed for use in activPilot Select hardware systems, typically installed in large tilt-and-turn windows with sash hinges. Suitable for professional fenestration projects, it is compatible with window frame materials including wood, aluminium, PVC, and steel, enabling flexible application across residential and commercial building sectors.

Its defining feature is the dual octagonal mushroom locking points, which provide enhanced security and smooth operation compared to standard single-point gearboxes. This specification ensures stable closure and increases resistance to forced entry, reducing risk for buyers seeking hardware for large-format windows. The GAK.2225-2 is especially suited to OEM window manufacturers or contractors installing tilt-and-turn systems in new builds or high-rise renovations.
