Spanner size for 1 1/2 inch seacock

Chris

I bought that one when I did my seacocks. Needed to cut off the old ones by grinding the outside head off, Access is always the problem and in Jeanneaus case they put the seacocks in before ant bulkheads or other fitting!

Luckily there is quite a bit of room around the seacock to work.
