U Bolt

Good U bolts They hold as thye should an when they get all rusty and locked up they are still weak enoungh to snap off with a little help from a breaker bar.

Perfect fit

I thought my ubolt was going to be easy to find at west marine or my local hardware store. Nope! Searched the web for several hours before finding pacific trailers.com they got everything!

Just how described and quick ship

Marty M. (Iron Mountain, US)
1/2" square U-bolts

Exactly what I ordered. Friendly person that took my order. These work perfect for boat lift, I had to remount and move my bunks. These are very hard bolts to find for 5" tubing let alone in stainless. Order came in a very timely manner. Thank you and will buy from again. Marty
