1/2" Square Zinc Plated Trailer U-Bolt w/lock nuts A=5 1/8" B=3"

Perfect

High quality U bolts, and exactly what I needed to repair a broken U bolt on my Sunstream boat lift bunk bracket. Finding 5" square U bolts that are not too long is not easy. These were a little thicker than the original ones I had, but I was able to just drill the holes on my brackets slightly larger (from 3/8" to 1/2"). Shipping was quick.

Exactly what I needed for a 5"× 2" boat lift beam

For boat lift bunk board riser attachment. Confusion with delivery arrival between this site and us postal service which was a few days later but got my package

Perfect fit and exactly what I needed.
