Bank size: It does not necessarily refer to the total number of compartments, but rather the number of compartments wide the entire cabinet is. So a bank of three may contain six lockers, for example, if they are two-tier lockers. In short, the total number of lockers is the bank size multiplied by the number of tiers. Sometimes the term "bay" is used instead of "bank", although "bank" appears to be the more standard term; on other occasions, "bay" refers to a single locker width within a bank, including all tiers of locker directly on top of each other.
Stepped/2-step lockers are two-tier lockers, usually available only in 15-inch (38-cm.) width; but the compartments and their doors have an L-shaped cross-section, which causes the division between the doors to follow a zigzag pattern. This configuration enables more hanging height to be included in both upper and lower lockers; but part of each compartment (the lower part of the upper one and the upper part of the lower one) will be only half the usual width of two-tier lockers.

I must stay, I was a little reluctant on buying this product because of the lack of reviews, but I am not disappointed at all. This product is EXCELLENT. I was a little overwhelmed with the installation process at first, but after emailing back and forth with the seller they were able to send me step by step video instructions. It was super easy to install and looks great. The individual keys are very well made. Highly recommend it
