Okay, time to test the extremes of 'OT' and see how far the sagacity of the STW massive extends…
I live in a Victorian house. Previous owners opened out the front room and 'dining' room, putting double doors between them.
When the previous owners had a loft conversion, it was a condition of building regs compliance that every door had an automatic closure device fitted. Now, these things were lethal – they'd cause the internal doors to slam very quickly and very loudly.
Because of the way we use our house, the door into the 'dining' room is the main entry into the house from the hallway. I took the closing mechanism off it, because the door became tantamount to a deathtrap.
However, it still slams, and very noisily too. We used to just hook it open, but since we've had a child we want to limit our cat's access to the upper floors so keep it closed. Basically, whenever we want to move around the house, this door has to the opened and closed.
Is there any sort of device, similar to the door closure mechanism, that would allow the door to close as normal and then damp the last couple of inches to prevent the slam?
Would something like this do it?
