Using this product, our team found that these ratchet hooks did not disappoint. The break strength of 10,000 pounds was impressive and made us feel confident in the security of our cargo .The hooks WERE easy to attach and remained in place throughout its journey. The black-coated finish has held up well against wear and tear. One downside we noticed is that the hooks were a bit heavy, which may not be suitable for some applications. Overall, a great buy for any industrial and scientific material handling needs..
