Just what I needed
I purchased eight of these to replace and upgrade the original u-bolts that attached the keel roller brackets on my boat trailer. They fit perfect and are stronger than the 3/8" u-bolts they replaced. Hot-dipped galvanized, and I really like that the washers and nuts are included. A+++ Perfect transaction all the way around. Thank you.

U Bolts
Best price for all Sturdy Built U Bolts. A plus having the nuts and washers included as other suppliers don't offer that.
