The Deep Blue Suction Cup Mount 18in Acrylic Lure Rack is designed to solve the problem that exists in other lure racks. The old racks tend to bend and sag when tackle is hung on them eventually pulling the suction cups loose. This rack has a 2″ x 6″ tab bent at 90 degrees to the surface and serves two purposes, one to make the rack more rigid to prevent bending, and two to support as much weight as you want to put on the rack without being able to pull the suction cups loose. Deep Blue also incorporated 2 knife slots in the rack along with 54 holes for lures, rigs, hooks, and tackle. Covered by the Deep Blue lifetime warranty.
