Siegenia SI Favorit Trial Tilt Turn Drive Repair Gearbox 1 X Number

• Hardware

The SI Siegenia Favorit tilt turn window lock mechanisms are no longer made, however we have been able to source and create an excellent solution. The new Siegenia gearboxes FAVORIT series is now avaialble as a matching replacement spare part. The 2 sides of the gear box parts are connected with metric PH1 screws which is avaialble as a common screwdriver or bit (not included). Siegenia Favorit Trial drive gears always came with the lock in the central open position. Inside the gearbox Siegenia position the gear with a break off burr inside the lock to prevent the lock moving whilst it is cut down to length to suit the particular patio. On first operation it will feel like the lock is jammed but as you exert some force on the handle you will find the burr breaks off and the lock will now run free from here on in.
