Avantis / Avanco replacement gearbox

Replacement centre gearbox for a matching Avantis / Avanco door lock. Use the main photograph and technical information to compare your existing part before ordering.

Choose the required backset and match both spindle positions. Check the distinctive deadbolt-above-latch layout and the connecting points.

Measurements and specification

Backset 35 / 45mm
PZ centres 92 / 62mm
Operation / application Twin spindle

Check the fit before ordering

Measure backset from the front edge of the fitted faceplate to the handle-spindle centreline. Measure PZ from the handle-spindle centre to the centre of the round cylinder opening.

Compare the case shape, spindle arrangement, fixing holes and drive connections. A matching brand or backset alone does not confirm compatibility. Select the correct backset option before adding to your basket.

Test the mechanism with the door open before closing it. Do not force a binding handle.

What is included?

One replacement centre gearbox. Cylinder, keys and handle spindle are not included. The complete multipoint locking mechanism and handles are not included.
