Fits Perfectly and Feels Durable

I was a bit skeptical about the "lightweight" description, but it's very strong. The fit is precise, and the Dacromet coating is a great feature for saltwater environments.

Exactly What My Trailer Needed

My old brackets were rusted out. These new ones are perfect. Lightweight but feel very sturdy. The Dacromet finish is a huge plus for marine use.
