Please Note:

Please check your replacement window locks ‘Backset’, this is the distance from the front of the lock to the center of the spindle as shown here. This is to ensure your new window lock will fit into the position of the old one, however, if you cannot get the exact match it is possible to open up the hole on the frame by 1-2mm with a drill. It is also advisable to ensure you order the right length window espag for your window. As we have several suppliers our espags can differ from the photos shown, some of our espags are shorter than the one you ordered, this is not an issue and you just need to retap the screws in the new holes and push the receiver to the new mushroom cam position.

This window locking mechanism is also suitable for most PVC windows, it is also suitable for Munster Joinery Window Repairs. Do you need mechanism keeps or receivers? You can choose from our window lock receivers here.
