Latch Hinges combine a hinge and a latch in a standard piece of hardware. Latch Hinges may or may not include a spring release. The Latch Hinge / Spring Release hinge has either a pair of spring-loaded handles or a single handle, which pulls toward the center to release the body or door from the keeper. An alternate style relies on an engagement hole or slot in the adjoining surface.
