The PRIME LINE PRODUCTS SP 9612 is a single loop closed extension spring built from durable spring steel with a nickel-plated finish. It measures 7/16 inches outside diameter, 23/64 inches inside diameter, and 2-3/4 inches in length with a wire diameter of 0.034 inches. The spring handles a maximum safe load of 3.57 pounds and allows up to 6.08 inches of maximum deflection. The corrosion-resistant nickel plating makes it suitable for both indoor and outdoor installations. This listing includes 2 springs. Handymen, maintenance techs, and general contractors reach for this spring when a reliable, off-the-shelf tension solution is needed for light mechanical assemblies.
This spring is suited for residential and light commercial maintenance applications where a compact extension spring is required. Common uses include door hardware, screen assemblies, cabinet latches, small appliance linkages, and general mechanical tensioning tasks. The closed single loop end configuration allows for straightforward hook or pin attachment in standard spring anchoring points. The nickel-plated finish resists rust and corrosion, making it appropriate for installations in humid or outdoor-exposed environments such as garages, utility rooms, and covered exterior fixtures.
Designed as an OEM-style replacement or general-purpose extension spring for light mechanical, door hardware, and maintenance applications requiring a 7/16 inch OD single loop closed extension spring.
Installation is typically performed by maintenance technicians or general contractors using standard hand tools. Before replacing a spring under tension, relieve all stored load from the assembly to prevent injury. Ensure the mounting hooks or anchor pins are rated for the spring load before installation. Verify the replacement spring dimensions match the application requirements before final assembly.
