deadlock

Hi Just removed a deadlock from a fire door and it’s an unusual size? The case/depth is 76mm/3” but the backset is 44mm. The only locks I am finding with 44mm backset are 64mm/2 1//2” ? Anyone advise please. Thanks

Hi there I have just replaced all the interior door knobs in my house. The old owners had installed deadlocks on all the doors and now I have large holes in the door that need to be filled. I have attached an image so its easier to understand what I need to fill. What's the best way to fill...

Hi We have wooden patio doors and the deadlock has broken. I am looking to try find a replacement but cant find it. Anyone with experience / recognising the deadlock know where I can find?
