They are usually intended for use in public places, and intended for the short- or long-term private use of individuals for storing clothing or other personal items. Users may rent a locker for a single use or for a period of time for repeated use. Some lockers are offered as a free service to people partaking of certain activities that require the safekeeping of personal items.
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.
