    Abstract: A protective, retaining device for shelf items stored in refrigerated or unrefrigerated enclosures to protect the items from spilling or breakage when the enclosure is jarred or moved is disclosed. The device of this invention is particularly adapted for use in recreational vehicles. The device consists of parallel, mutually spaced rods interconnected by at least one support. Each of said rods telescopes, and is longitudinally adjustable and spring-loaded. In addition, each rod has a skid resistant foot at either end so that the device may be mounted between opposed structural walls to retain objects on storage shelves while permitting access to the objects without removal of the retaining device of this invention.
