Overview
The CAP OPR6IS-045 is a 45-pound plate built from alloy steel and rubber, priced at $46.99. It sells 2,000 units per month and has accumulated 3,975 reviews at a 4.5-star average. Those numbers are not close to any other plate in this category. For a standard 45-pound plate, this is the de facto market leader based on buyer data.
