These requirements cover the construction and security of night depository entrances. The units are intended to permit the deposit of cash, checks, and similar items, from outside a building into a chute connected to a depository within the building. A night depository is intended primarily for protection against theft of deposits by: a) Fishing the deposits from the depository; b) Trapping the deposits by preventing them from entering the depository, and then extracting the deposits; and c) Entering the night depository by force with the aid of common burglary tools.
