Door lock style width

[iwilson16]

Is an 85mm door lock style wide enough for modern 5-lever mortice locks or lockable handle rim latches?

Thanks

yes, an ordinary 65mm mortice lock case will fit if you are neat. That's probably what you already have. Take it out and measure it.

There are a few narrower ones such as the Chubb (now Union) 3G220.

You can also fit a Narrow Style BS3621 nightlatch. It is called 40mm size, but this refers to the backset of the keyhole, not the case which is wider.

I also forgot to ask ... there is an 8mm gap between door style and frame, so the existing mortice deadbolt only just catches the strikeplate (sometimes it doesnt though!).

Whats the best way to fix this? Pad out the hinges? Pad out the strike plate? New door?

I might just get a new door anyway. The current door is glass panels, so not the most secure. It opens into a common stair shared with one other neighbour. The maindoor to the building only has a yale type lock on it.

I would be inclined to put a woodstrip in the frame, then re-fit the strike plate. Use good big screws so they are firm in the frame itself.

The current BS3621 has a longer bolt throw, but you should always minimise the gap.
