SI Siegenia Tilt and Turn TBT Drive Gear Upvc Lock Mechanism – GR60 601-1000
This part is designed to replace the broken gearbox on your Siegenia tilt and turn windows and tilt and slide doors. It comes in two halves which you simply fix together with the included fixing screws. The screw housings are supplied with centre fixing as mounting aid. That is, the gears are fixed for mounting in the rotational position. After installation, a breakage point breaks during initial operation and the gearbox can be used freely.
