3/8 inch/10 mm square stopcock key wanted

[robinmj]

I can't locate a key to turn off the external stopcock. I can find 3/4, 5/8 1/2 inch square keys, but not a 3/8 inch. I've tried a tapered socket without success. Help gratefully received!

stopcock handle missing!
use a small adjustable or make one

Thanks Redsaw, but it's about 2 feet down inside a smallish (c 6 inch diameter) plastic lined hole.

expect so as normal, done loads. should just be able to reach down to it.
otherwise get 3/8'' socket set ext bars and use the square hole bit over it and other end in a chuck to turn.

thats how i wind my car jack as thats 3/8ths
