Perforated lockers are similar to the standard types of locker, but the door and walls are made largely or entirely of perforated steel, with hundreds of holes creating a strong mesh arranged in a diagonal pattern. This is used where good ventilation is required, or where, for security reasons, it is necessary that the contents can be examined visually while the doors are locked. 

But now, the city has announced it will spend $160,000 on two pilot projects to provide 210 more storage lockers for those experiencing homelessness. Some service providers say the announcement is a move in the right direction for the city, which has found itself the subject of harsh criticism and even a federal class-action lawsuit over the enforcement of its camping ban.
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.
Rebecca, I remember a previous post that a visitor found storage at the bus station, so I called to see if still available, and it is. Lockers are $3 for the first hour and $1 per hour after that. It's difficult to find storage short term because of security/liability, esp. since 9/11. If you are staying at a hotel, they will often keep your luggage for you short term.

Other advocates of lockerless schools also cite reasons such as reducing noise by eliminating the clang of dozens of locker doors,[1] or creating a more appealing environment aesthetically. It has also been claimed that removing lockers provides good training for students by forcing them to be more efficient in managing their books, and taking the time to plan what books they will need, and carrying only those ones.
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.
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.
