Excellent quality, holding my boat guides on with these. Work great.

Jeffrey S. (Seaside, US)
Fit perfectly.

I ordered 4 6” square u bolts and straps to replace the rusted ones on my old boat trailer. The new ones fit perfectly and are now made of stainless steel. The person who helped me on the phone was knowledgeable and efficient. The parts arrived within a couple of days and were packed and shipped well. 5 star service.
