KEY DOOR

Doors are common in restaurant equipment design from refrigerators and freezers, to ovens to ice machines. A door is a hinged or otherwise movable panel that allows access to an enclosure, cabinet, bin, or other cavity or container.  A door assembly comprises the components that work in tandem to allow the door to function properly such as the door set, strike, catch and lock set. Doors may be hinged and swing open and closed, or they may slide within a frame. Very frequently, restaurant equipment doors feature tempered glass windows which allow for visual inspection or merchandising of food and beverage products.

A key is a small, shaped metal implement for operating a switch in the form of a lock. A key may similarly be a pin, bolt, or wedge inserted between other pieces, or fitting into a hole or space designed for it, so as to lock parts together. It may have incisions cut to fit the wards of a particular lock, which is inserted into a lock and turned to open or close it.
