Sloping tops: while most lockers have flat tops, some manufacturers offer the option of sloping tops to their range of lockers. The slope may be of either 30 degrees or 45 degrees to the horizontal, sloping towards the front, and the purpose of this is to make it impossible to store items on top of the lockers, or to make it harder for dust or other debris to accumulate there. This is an important factor in places like food-processing factories or restaurants where hygiene requirements must be met.
Other advocates of lockerless schools also cite reasons such as reducing noise by eliminating the clang of dozens of locker doors, 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.
When looking at Pallet Racks as a storage solution, consider the needs along with the physical requirements of your business before investing in a complete pallet racking system. Industrial Storage Rack configurations should consider accessibility to individual loads (selectivity), handling time, the efficiency of space utilization (storage density), order fulfillment speed, along with acquisition expenses.
Gun lockers or safes are specifically designed for the secure storage of guns and ammunition. They broadly resemble normal single-tier lockers, but tend to be slightly less high than normal single-tier lockers, and are often free-standing, and not banked together. They are fitted with internal racks designed for holding firearms. They have a shelf at the top like normal single-tier lockers, although in this case it is closed and locked by a separate door, because of legal requirements in some countries that firearms and ammunition be stored and locked separately. They always lock with three-point locking, which is in some countries a legal requirement for the storage of firearms. Sometimes they are made of the standard kind of sheet steel used in manufacturing normal lockers, and sometimes they are made of extremely thick heavy-duty steel and in this case resemble a safe more than a normal locker. In Australia there are strict regulations governing the storage of firearms following the Port Arthur massacre in Tasmania, Australia on 28 April 1996, and cabinets used for storing firearms must be bolted to the floor or a wall if the cabinet is under a certain weight. Dedicated gun lockers are likely to include holes in the cabinet to accommodate such bolting. Several locker manufacturers also offer dedicated gun lockers.
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. 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.
