This cable with swivel hook is massively strong and surprisingly heavy, much stronger and heavier than I expected or needed. However, after adding a separately purchased cable U-clamp, it performed as desired, pulling our boat lift in to shore behind our vehicle over a shallow but uneven lake bed. 3/8" sounds small, but I probably could have used 1/4" or even 3/16". If you have something really heavy to tow, this will work great!
