The products of DC Cargo Mall are first class. I royally taped my Kubota MX6000. We used their 5/16" grade 70 chain to pull it out. The first attempt was with a Ford F250, the second with a JD 5075 tractor, neither was successful. Cat D5. It took D5 two and a half hours to pull it due. When he pulled it out he was also using DC Cargo Malls 5/16 "Class 70" chains. None of the chairs broke or stretched. I would highly recommend DC Cargo Malls products and their customer service is second to none!
