PLATE DOOR HINGE LH PS570

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 hinge is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them. Two objects connected by an ideal hinge rotate relative to each other about a fixed axis of rotation: all other translations or rotations being prevented, and thus a hinge has one degree of freedom. Hinges may be made of flexible material or of moving components. In biology, many joints function as hinges like the elbow joint.
