Engel Bait Trays are made in the USA from high quality .080 powder coated aluminum for a lifetime of use. * Our standard trays are 2.3-inches deep and make it easy for any angler to properly store and keep fresh a variety of rigged baits, including whole ballyhoo or even rigged strip baits. * Our deeper 4-inch deep trays will accommodate frozen boxes of sardines, squid, swimming mullet, spanish mackerel and chum. * Using a design where interlocking trays conduct cold from one tray to the next, bait stays cold and dry all day in the sun. This system uses less deck space and ice than conventional bait tray systems. * To be used with ENG35 DeepBlue Cooler
