Composed of commercial quality steel, BizChair.com's four tier lockers are durable enough to withstand industrial or student usage. Remember when forming a group of lockers you must purchase starter lockers (for the ends of your grouping) and adder lockers (middle pieces) to form the group. Also, determine how many lockers you need and what locker number you need to start and end on to create your locker group. When purchasing a four tier locker, remember to consider whether you need a built-in combination lock, key lock, or prefer to have space for a combination pad lock.
