Our powder-coated metal, knockdown lockers are the most popular line we sell. They are sturdy, durable, and come in a wide range of colors. They are offered in single tier, double, triple, and more depending on the needs of your project.

Athletic lockers are available as well as solid plastic (great in rooms with showers), plastic laminate (great finished look for an office), or wood (athletic team room).
