Thread: what lock should I use

photos would be a big help.


fitting any sort of lock to hollow doors could be a challenge

Assuming it's two doors that both open in opposite directions, the usual method of securing these (provided there is no option to secure one from the inside using a bolt that slides up at the top and one that slides down at the bottom) is to use what is known as a block lock. Googling this will lead you to much imagery and many products.

They're pretty much, from what I understand, designed to secure two swinging doors together.

Pretty they ain't, secure they are.

Thanks, but from what I've seen a block lock seems to be designed for sliding windows. I'll look into it a bit more though. Cheers.

Could you use a flush bolt in the edge of one door then a locking catch in the other?

I can definitely put a simple bolt on the inside of one door. But what's a locking catch? When I look that up online, I get images of gate locks.

Hefele do a magnetic lock that would work quite well in this situation. there is no exterior evidence of where the lock is, or how to open it.

Locking catch into the 22mm door. The barrel extends 20mm therefore the back would have to be recessed in 2mm

Maybe a lock like this (or others they list).

I'm sure there are a myriad of solutions and it depends to a certain degree on how secure and/or decorative you want the fixing to be. A better looking hasp and staple type approach might be to use something like this one on ebay . It gives you the option of just latching the doors or securing by adding a padlock.

Yes, that's what I got for the thinner door - but unfortunately the door is 24mm and the catch is only suitable for a 22mm door.

Your dilemma has highlighted the need for all of us to plan ahead and change components to get a satisfactory end to a job
