Hi,
Im currently about to fit new doors with rose type handles to all the doors in my house. For the standard doors Ive brought a latch(?) that is spring loaded so that will go inside the door and provide the spring force required for the handle return.
However, on my back door this has got a combined lock and latch fitting. Do these also have a spring? Im sure when I have taken off the door handles in the past for painting the return spring has been part of the handle and not part of the lock mechinism. If so what do I need to buy to give me a combined lock and sprung latch?
Also - I was thinking about replacing the additional bolt type locks on the door with the yale type ones that fit into the actual door. Will drilling the hole to insert the lock weaken the door and make it less secure that the bolt type locks?
Cheers,
CM.
