Tilt and turn window not locking, tilting or opening properly? The fault is usually either the handle or the drive gear inside the window that the handle turns. Both can be replaced without changing the window.
We stock tilt & turn window handles from Hoppe and Fab & Fix, and tilt & turn drive gears from Hautau, Maco, Siegenia and Roto.
If the handle is cracked, loose or the lock is faulty, but the window works when you turn the spindle, you only need a new handle.
If the handle turns but the window won't lock, tilt or open, the drive gear behind the handle has usually failed.
Measure the spindle length from the base of the handle to the tip, and check whether you need a locking or non-locking handle.
Look on the faceplate for the brand and any part number, and measure the backset and faceplate. Drive gears are specific to each hardware system.
On most tilt & turn windows, handle down is locked, sideways opens the window inwards like a door, and up tilts the top of the window inwards for ventilation. The handle turns a drive gear in the edge of the sash, which moves the locking points round the window.
Close the window and turn the handle to the locked position. Lift or slide the cover on the handle base, undo the two screws and pull the handle out. Fit the new handle in the same position and check it moves cleanly between locked, turn and tilt.
Drive gears must match the make of the hardware in your window, such as Hautau, Maco, Siegenia or Roto. Check the markings on the faceplate and compare it with the product photos and sizes before ordering.
The window may be slightly open or out of line, so push it fully closed and try again. If the handle still won't turn, or turns without moving the locks, the drive gear may have failed.
The fixings are similar on many, but the spindle length must suit your window. Measure your existing spindle before ordering.
Usually not. The drive gear has to match the rest of the hardware in the window.
