Coldseal/Mila/Swift Frame Gearbox for Coldseal/Mila/Swift Frame Multipoint upvc Door Lock

This is not a counterfeit Chinese copy, it is a genuine Mila/Coldseal lock made by the original manufacturer based in Europe. Many of our competitors are selling a cheap counterfeit copy.

The central gearbox is usually the part that fails. To switch the Coldseal gearboxes, remove the two fixing screws on the metal strip that hold the gearbox on, remove the gearbox, connect the new gearbox (making sure the metal sliders locate into the gearbox then re-fasten the screws back in). You may wish to purchase a "star" screw head for the screws, available below.

N.B These Coldseal gearboxes will fit onto 95% of Coldseal/Mila multipoint locks. See the photo below to check if your connectors occur in the same place.
