Extension Springs - 5/8" x 2 1/2" - Zinc-Plated - 2/Pkg

This zinc-plated extension spring absorbs and stores mechanical energy while providing controlled resistance to tensile forces applied during stretching operations. The coiled steel construction enables precise extension under applied loads and automatic return to original length when tension is released. These springs are commonly used in garage door systems, trampoline assemblies, exercise equipment, automotive applications, and various mechanical devices where reliable spring-loaded tension control is essential for proper operation in residential, commercial, and industrial settings.
