Spring 580936-00

This is a genuine manufacturer-sourced replacement part which is specially designed for Black and Decker and DeWALT string trimmers. The purpose of this spring is to apply tension on the actuator, allowing it to retract. If the hardware is worn or damaged, this will provide an identical replacement for the original component that was installed on a new unit. Refer to the appropriate diagrams for your model to ensure the exact location and the correct repair procedure. Note, this high-quality spring is made of durable metal and is sold individually. A screwdriver will be needed to perform this repair.
