I think my failure came because I was trying to use 3/8" fittings. Seems they adapted a 1/4" straight thread (british fitting??) up to 1/2" NPT, then tossed on the the flat faced couplers.
This was on top of using a non-standard hose, as my first thought was, lets cut the hoses and put standard fittings on one end.
FAIL!
Oh well, in the end, I now have standard hoses and fittings. Just frustrated, I dont see how they may have saved $$ by going this route. Heck, the flat faced fittings are PRICEY. I guess add this to the shipping hangups that happened to me, and it just left me with a sour taste. Mind you, in their defense, I have not spoke with them about any of this really. I am just rolling with it.
The actual grapple itself seems to be great. It fits the SSQA perfectly. Opens and closes as designed. I have not gotten the open measurement, but as you can see in the pic I posted, it would be difficult to really determine what measurement to really go with.
I hope to get more time with it tomorrow, and learn some more.
