Would this work? Adjustable roller catch?

To satisfy usual insurance you need a 5 lever mortice lock to BS standards.

 

Best to re-think!

 

Would a decent door closer do? Alongside a quality lock as Chippie suggests it will be the same as most personnel doors on business units and similar places.

 

Chippie244 is correct, to satisfy the insurance company you should use a 5 lever mortice lock, using a lesser lock just because you don't like getting locked out, wont wash with an insurance company, should you have any intruders, the yale (PBS1) auto deadlock is more than suitable which is about £60 . With home security, don't take short cuts, be safe, not sorry

So what's wrong with a mortise lock with catch and knobs?

Mr. HandyAndy - Really

 

He doesn't want one, try reading the post.

You can go ahead with that, that comply' s and will serve your needs.

If you are having problems with locking yourself out, then install one of these out of direct sight:

When mounted properly they are incredibly secure, I spent about 20 minutes cutting one open with an angle grinder. I needed to get the master keycard and the person with the lock code was on holiday, but when I finally did cut in, the card had melted.

 

I reads the post dumbo.

His idea was to have something that doesn't automatically lock when closed. a mortise as I said would provide.

Lying again.

 

A perko, they work but watch your fingers, check you have enough clearance for the mechanism.

 

I am not lying chippie. Don't start on this thread. You will lose again.

 

DVD, you've sussed out the pitfalls

Yes, it can be done. But if you rely chust on a roller type catch, then it would have to be mighty stiff to prevent the door being blown open by, say, another house door being opened. And if you made it that stiff, then it would be really awkward to physically open in normal use.

So, possibly a decent concealed closer, as you suggest, along with a 'normal' roller would work. That comes with its own issues, of course - like always having to hold the door open - eg when carrying yer shopping through, or chatting to yer postie.

Really not practical long term, I don't think.

I wonder if there's something that works a bit like a car door handle that's suitable for normal doors. Ie, it looks like chust a fixed handle, but it pivots and acts on a latch when pulled on?
