This universal washing machine door boot gasket seal retaining ring tension expander tool saves time and makes door seal removal and fitting easier. The Expander simultaneously spreads both ends of the gasket’s tension spring, allowing the metal cable to loosen, making it a one-man job to replace the gasket. Designed for front loading washers, but can be used for other items that require springs to be expanded. Universal fitting for most door seals. Paxanpax reference: PLD1822
