Each spring measures 5\/8 inch outside diameter, 29\/64 inch inside diameter, and 3 inches in length, with a wire diameter of 0.08 inches. The nickel plating allows for use in both indoor and outdoor environments. The spring is rated for a maximum safe load of 44.2 pounds and a maximum deflection of 1.34 inches. This listing includes two springs per pack. Handymen, maintenance technicians, and trade professionals install these springs in a wide range of residential and light commercial applications.\u003c\/p\u003e\n\u003cp\u003eThese extension springs are suited for use in screen doors, storm doors, cabinet hardware, light-duty machinery guards, and general mechanical assemblies where a reliable return force is needed. The closed double loop end configuration provides secure attachment to hooks, pins, or anchor points. The compact 3-inch length and 5\/8-inch OD make these springs a common replacement in tight-clearance installations. The nickel-plated finish resists rust and surface degradation, extending service life in humid or outdoor-exposed environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble loop closed end design for secure hook and pin attachment\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch outside diameter and 3 inch length for compact fitment\u003c\/li\u003e\n  \u003cli\u003eMaximum safe load of 44.2 pounds\u003c\/li\u003e\n  \u003cli\u003eMaximum deflection of 1.34 inches\u003c\/li\u003e\n  \u003cli\u003eNickel-plated spring steel finish for indoor and outdoor corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eSold as a 2-pack for common replacement needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement extension spring for residential and light commercial hardware applications requiring a 5\/8 inch OD double loop closed extension spring.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eExtension springs store energy under tension and should be installed and removed with appropriate hand tools to control release force.
