The perfect accessory for storing small, hard-to-manage pieces of terminal tackle, the Plano EDGE Weight Retainer Inserts are designed to work in tandem with Plano’s revolutionary EDGE tackle storage system. The new EDGE Weight Retainers fit inside various sizes of EDGE Utility Boxes to secure your weights within rubber inserts under a tight closing lid. The rubber inserts keep your weights in place to help reduce chipping and damage and prevent them from becoming mixed up in other compartments. Each lid has a label section that anglers can use to identify exactly what size and style of weight is within each compartment. The EDGE Weight Retainer Inserts are designed to fit the 3500, 3600 Terminal, 3700 Terminal and 3700 Thin Plano EDGE Utility Boxes.
