I afraid I didn't understand you question ?
stand for what I think it does!!
what do you think about that ? 
It looks good, I like the Stainless Steel handle.
Sorry, It was a lame attempt to be humorous. What does P.O.C stand for?
Oh, now I see, piece of cake. Man sometimes I am thick.
no prob, i don't know all english, so i just wrote that i didn't understand well
joking is good, so go ahead :)
A good looking tool. A friend of mine made me a crank too, its made out of wood and steel. It only works with the cup type connection, not the pin.
I'll post a picture of it in the future.
I thought these things are called a P.I.S.S.T.A.K.E.............Piece in stainless steel to alleviate knuckle exertion.
Man, you must need some serious downhaul to have to use that...
I do all mine easily by sitting down and pushing with my foot.
Perhaps it's a Professionals Only Contraption 
i rig my loft O2 with foot and it is very easy
we made this for all others our members who had lots of problems
to rig like gtx, vapor, and others, mostlyolder types of cam sails
and btw POC works with all type of pins becouse it have only
straight pin to fit any base or extension :)
and name, hahahaha, i supose that there are lots of funny name like
ours, but we think, POC is a cool name for that
thanx everybody for backing me up here and for join in discussion
@JP747
POC have margins for part for downhouling, like picture you posted
in POC case the ARM can't go left or right without control, becouse
of that margins
i don't use the crank anymore but instead downhaul rope coated with candle wax and tied around a 30cm hardwood i believe there's more feel to it if something gets stuck or not downhauling properly cuz the cams are misaligned something like that
but for people with back pain it's a necessity
I use (homemade) inox tube 30cm long with 2 holes in the middle
and dawnhouling with that and with my foot
anyway, my lofts O2 is very easy to rig even with just rope and foot
