Review on CSI W512 Winch Shackle - 4.75 Ton Capacity: Ultimate Strength for Heavy-Duty Towing by Ronnie Dabolt

I ordered these based on the VERY limited technical information published by Revain in hopes that they would work. It's a metric, as noted by another reviewer. The shackle is just under 3/4" and the bolt is just under 7/8". The shackle has a lifting capacity of 4.75 tons. I never received a tracking number because I believe it was an international shipment. I read that CSI products are made in China. The powder coating had a few chips but looked good overall for only $20. I hope that some of this information will help some of you with your purchasing decision.
