The SI Siegenia tilt and turn window kit comprises of the SI Siegenia drive gear mechanism which the tilt and turn handle operates. The main part of the SI Siegenia tilt and turn kit is the gearbox/mechanism which operates all the other components of the SI Siegenia tilt and turn kit such as the top and bottom drive corners. The top corner engages in a locking keep/striker at the top/side of the window, the bottom corner engages in the bottom/side keep as well as the tilt keep/stricker at the bottom of the window. The drive gear mechnism also operated the scissor stay mechanism which operates the tilt action and the backbolt mechanism which locks into the keep/striker on the hinge side of the tilt and turn window. The SI Siegenia tilt and turn bottom extension piece is also required when the tilt and turn is over 1000mm in width.
