Mila Multipoint UPVC Door Locks
Many of the Mila Locking systems have been discontinued due to factorys shutting down in China. Many of the Locks made by Coldseal were included. If you have a lock that has Coldseal printed on the front and it has a 35mm backset try renewing just the gearbox in the link below. It is very simple to do and will save you a lot of money.
