The Dualframe 75mm Reversible Window System has a wide range of applications where specifiers wish to incorporate windows that can be safely and completely reversed for cleaning. Reversible sashes incorporate hardware which ensures balanced operation in use.

Safety catches prevent inadvertent reversal. The reversing action does not interfere with items around the window, such as curtains, objects placed on window boards or reveals. Vents are hung on top of overswing hinges with integral restrictors, which engage at initial opening stops and fully reversed positions for safe cleaning.
