With their tight-coil design, extension springs are engineered to absorb and store energy while generating resistance to a pulling force. Common extension spring applications include: automotive uses, garage doors, trampolines, and machinery. All springs are galvanized to prevent corrosion. All springs meet ASTM standards. Please consider the -inrate per inch-in and -inmax load-in when choosing a spring. Rate Per Inch: the amount of weight a spring will withstand per utilized inch. Max load: the maximum load a spring should withhold in total.
