I was trying to figure out what "full slacK" means. Does that mean the two vehicles are touching?
"I mean full slack on a 30ft snatch strap, then full throttle in 4LO in my 3/4ton Duramax". Ummmm why?

Product Alerts
Over the years there have been numerous alerts issued concerning the authenticity of Crosby products. These alerts have resulted from an alert that was generated by a company other than Crosby. The content and photographs of the subsequent alerts are the same as found in the original alert with new titles or sponsoring companies. Crosby provided responses to the original alert at the time, resulting in a retraction from OSHA. The responses, which are still valid today, provided clarification as to the marking of Crosby shackles and issues concerning the reduction in the working load limit.

disregarding the lack of brain power or experence in the previous post.....
I am a certified crane operator and i used to run the rigging department in an 1100 seat theater. we riged things like Peter Pan, Miss Sigon... big just off broadway shows. We threw away every non-forged peice in the rigging cabnet from the previous rigger. cable clips, turn buckles, non-stamped shackles, unrated-no name sleeves... etc.
always use CM or Crosby for all of your rigging. Do not go to Home Depot or Ace and buy cheap, china made, diecast parts. They will fail, they will kill someone. I always zip-tie the 2 part shackles. 3 part are required where I work.
whatever shackles you buy make sure it has the manufacturer name on it and the safe working load. that in itself sets it apart from non certified brands. made in china is ok as long as it is properly stamped and certified.
you will notice on most china generic brands depending the company will either not have the manufacturer symbol or name, or will not have the safe work load. if its not stamped it has not been tested or rated.
also some generic china brands even with the markings will be rated differently. you may compare a china shackle that is 1 inch to a crosby shackle which is 3/4 inches and will have the same load rating. bigger shackle but same rating, they are using different steels and alloys which are not as good which down rates them..
for the most part certified shackles will have the same rating across the board according to the size, sometimes you may get a manufacturer like CM that has used better process and materials and will have a much higher rating for the same thing. you get what you pay for in this area.
also check the manufacturer to see what the safety rating on breaking strength is on that shackle. it may only be a 3:1 rating compared to a standard 5:1 and that is why it is cheaper
Exactly. There are cheap as crap factories in the US too. Get stuff from reputable companies, ideally ones that have some oversight and testing by an organization that makes sure the gear is upto standard. That kind of factory could be anywhere in the world.Otherwise this is just "China bad, USA good".
I bought some of the Warn shackles w/ a 7/8 pin (4-3/4 WLL) this week via the internet and they are made in China, too. Wish I had found this thread earlier.
