These all welded, heavy duty lockers are commonly used in gyms and warehouses because they are built to withstand heavy daily use. Each of these groups has 4 large compartments that are 18” wide x 16” deep x 36” high and 7 smaller compartments that are 12” wide x 18” deep x 12” high. The expanded metal back allows for extra ventilation that is often needed in these types of environments but does not jeopardize the overall security of the locker contents. We also have several types of new and used locks available that will work for these.
