I'm looking for an emergency exit door, the kind with a horizontal crash bar, about waist height, which operates long vertical bolts at the top & bottom of the door. They come in singles & doubles, the second door on the double has a crash bar which operates the crash bar on the door with bolts - like the one in this picture

The person I'd think of for that sort of thing would be Cyclonesue - sadly a poster at T$R. I'll see if I can find the link.

Edit: here - not a double though:

and bizarrely, the diagonal seems to be a separate download:

maybe talias 3t2 Conversion M91 Shipping Container Set http://simpearls.co.uk/simpearls/index.php?topic=1216.0
Maybe you have to register

The reason the diagonal door maxon linked to is a separate download is that it's from a set - and all the files can be downloaded individually. The whole set is here: https://www.thesimsresource.com/art...ims2/id/769777/

Thanks for the replies, Cyclonesue's creations should do the job

It's still bizzare MLC - normally doors and windows and their diagonals are in the same package.
