1/2 in chains

Since ive been pulling for ats, ive seen some loads that say 1/2 inch chains required. Military stuff. D rings and cut outs on the rgn trailers arent rated to g70 1/2 chain. Does anyone carry 1/2 in chains? Or just use more 3/8? Im thinking about buying 20ft chains and cutting them on half. Id have 4 10ft with one hook each. And yes ive got snap binders rated at something like 9200#s. If i use them often id buy rachets.

 

Im doing what they call a lease. I call it a rent. I live an hour from St. Cloud. Fleet farm has the chains. Closer to home. Are they needed? Should i get 4 10ft? One hook or two per chain?
I agree on the rachets. Ive already get snaps though.

 

The only time i checked was a tandem stretchable rgn. Sticker said d rings were 6600 i think. Cutouts 9200? Both less than 1/2 chain

 

How often you use the grab hooks?

 

I agree. Thats the way im leaning. I'll buy chains when i get home next week. You think 4 10ft enough? Buy 3 20s and make 4 10s and 5 4s out of them? Ive had the snap binders for years.

 

The rings were probably an inch. Sticker said 6600. Im guessing that the welded strap holding the ring was the weak point?
