In schools without lockers, students are sometimes provided with two complete sets of textbooks, one set being kept at school for use in class, and the other being kept at home for referring to for homework, thus limiting the amount of heavy carrying that would otherwise be required without having lockers to store them in between classes.[1] However, research has shown an increase in the incidence of back injuries in some students, which has been directly attributed to the lack of lockers for storing books in, thus forcing students to spend more time carrying heavy loads of books in backpacks.

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.

Some schools in the United States have been reported to have abolished the use of lockers. Security concerns are cited as the reason for this, with the concern being that lockers may be used to store contraband items such as weapons or drugs or pornographic material.[1] There has been some controversy over in what circumstances school authorities or law-enforcement officials are permitted to search lockers, with or without informing the users, or with or without the users being present at the time of the search, and it has been considered a civil liberties issue, particularly in the U.S.

Dimensions (Note that, in English-speaking countries, even those commonly using metric measurements now, locker dimensions are usually clean numbers of inches or feet, while the corresponding metric measurements are uneven, involving decimal places when precision is required, presumably resulting from continued use of locker designs based on feet and inches, unchanged for decades other than for cosmetic features.):

Lockers are usually physically joined together side by side in banks, and are commonly made from steel, although wood, laminate, and plastic are other materials sometimes found. Steel lockers which are banked together share side walls, and are constructed by starting with a complete locker; further lockers may then be adding by constructing the floor, roof, rear wall, door, and just one extra side wall, the existing side wall of the previous locker serving as the other side wall of the new one. The walls, floors, and roof of lockers may be either riveted together (the more traditional method) or, more recently, welded together.
