A catch or latch is a type of mechanical fastener that joins two or more objects or surfaces while allowing for their regular separation. A latch typically engages another piece of hardware on the other mounting surface. Catches range in complexity from flexible onepiece flat springs of metal or plastic, to multipoint cammed catches. Magnets are found in all kinds of restaurant equipment and serve many purposes. Magnets are useful for their stickiness with ferrous metals. In the simplest foodservice equipment designs they are used to keep swinging doors secure on rolling service carts. Some more complex uses integrate magnets with motorized systems to provide contactless magnetic drives as seen in certain high volume blending systems. Specifications. Height 1.55 in.. Width 8.8 in..
