I'm looking (probably along with a lot of people this week!) for a draught excluder for a mortice lock keyhole. My Mum is (rightly) complaining of the draught whistling through the door lock. It's for doors with a standard keyhole lock/handle arrangement where there isn't already an escutcheon. I could adapt a standard escutcheon, but I've been looking for anything that resembles a rubber plug (a true plug would get in the way of the key, and isn't ideal, but she'd probably put up with it for the sake of the warmth, but there might be a middle road).I've stumbled across a couple of possibilities, both on ebay (although now ended auction), but sadly the manufacturers have either disappeared or discontinued production. See: know there are plenty of escutcheon covers, which I could adapt, but having seen this rubber insert, I'd really like to exhaust all avenues of finding something like it before I use an escutcheon as the rubber stopper route is so neat (and very unintrusive). I could probably rig one up with a bit of old bicycle inner tube as well, but just (again) exhausting all avenues)Does anyone know of suitable/similar products?Thanks in advanceAllanx-post uk.d-i-y

"For the sake of the warmth"? Don't be silly. The chilling effect ofa keyhole-sized "gale" is likely to be subliminal unless one positionsoneself directly in the jet.But old ladies are impossible to convince on the basis of anythingrational, so I guess you do have to do *something*.Nothing wrong with a plug (or even a bit of gaffer tape). Put it on theinside, then you never need to remove it. One should only ever lock thedoor on the mortice from the outside (when one is out and no-one is in).Locking it from the inside is dangerous - you don't want to have to befinding and fiddling with a key in a panic when there's a fire and youneed to get out in a hurry. But perhaps even this is too rational andhence unconvincing.

I'm guessing, but I should think sand or dry powder or CO2.

It's a Class D (burning metal) fire, so you can't.

The US Navy have two techniques for class D fires: the first is to use "Purple K", a dry powder, but not the usual dry powder. This doesn't work (we demonstrated this). Their second technique is to throw whatever is burning (up to and including whole aircraft) into the Pacific.

Monnex. It is powder but would be better than ABC dry powder.
