Barn door stuck?

I just looked, there is no valve i cam find. But there MIGHT be a pin, At the corner there is a round bar thing for lack of a better word that sticks out around a 1/4th an inch. I dont see a pin on the outside but it may have one inside. I will figure out how to get my fat ### in the trailer with only a swing after i dump. And then i will see if it is there.

It does swing gate though. Last load was a swing and it worked fine.

edit: wow i cant english tonight.

 

Sorry for the late reply, i just shut down. That said yes and no. I found the pin, it was hidden by a flap of metal on my endcap. However when they welded said endcap in they accidently welded the pin in. Not a big deal but ill need to get an angle grinder to unpin the stupid thing.
