I just bought my first grade 100 3/8" chains. I got 4 @ 15' long with grade 100 Crosby (made in America) grab hooks that are pinned with a roll pin rather than cotter pins. OUCH, expensive, the hooks were actually more expensive than the chain. A bit over $600 for the 4 of them.
We noticed immediately that there was not stretch to them that we could get out of the grade 70 3/8" when binding down tight.
We are going to replace the rest of our grade 70 chains with these as needed in order to increase the working load limit and require throwing less chains on a load to meet DOT requirements (I still scratch my head over getting full credit for anchoring from trailer, over load, back to opposite side of trailer as opposed to cross chaining - that should be a thread in and of itself).
I should probably buy 4 - 1/2" grade 100's for 4 corner chaining of excavators, but will wait until more of the grade 70's need to be replaced. I have yet to have DOT officers do more than take a glance at how we have chained our loads down, and they have never added up the WLL of the chains to see if we are in compliance, but I am sure our day is coming.
