Midwest Fasteners Steel Replacement Extension Spring

Midwest Fasteners Steel Replacement Extension Spring

The Midwest Fasteners Steel Replacement Extension Spring is a steel SRA422 Ajax-series extension spring built to store energy and resist stretching, pulling two mounting points back together once a load is released. This family is available in two sizes, 5/16" and 3/4", so you can match the original equipment spring reference rather than settling for a generic substitute. Whether you are servicing light equipment or replacing a worn latch spring, matching the original SRA422 Ajax reference helps ensure correct tension and fit. Extension springs like these are used wherever a mechanism needs to return to its original length after being stretched, from latches and mounts to small equipment linkages. Built from steel for dependable cycle life in general equipment and repair applications, this spring ships in a carded pack for easy shelf display and point-of-sale restocking.
