Our polyurethane foam has a way of being strong enough to provide flexibility for items, but also dense enough to provide cushion for the toughest of items. This foam replacement can be used for a Plano 108361 case. This item includes 1 solid piece of foam that is 2.5 inches thick and 1 thin pad that is 0.75 inches thick. Each layer has rounded corners to ensure a snug fit. The material weighs about 2 lbs per cubic foot and dimensions are 37”x13x2.5”. We know how much value your precious items have and therefore have always sought out to provide the best quality foam. This foam is locally manufactured by COBRA FOAM in the state of California, USA.
