Prime Line Products Sp 9619 Closed Extension Spring 2 Pack

Product Description

The PRIME LINE PRODUCTS SP 9619 is a single-loop closed extension spring built for reliable tensile load applications in residential and light commercial settings. Constructed from durable spring steel with a nickel-plated finish, this spring handles a maximum safe load of 46.2 pounds and a maximum deflection of 0.95 inches. The outside diameter is 0.75 inches, inside diameter is 0.5 inches, overall length is 2.875 inches, and wire diameter is 0.105 inches. The corrosion-resistant finish makes these springs suitable for both indoor and outdoor use. Each package contains two springs.

These closed extension springs are a practical choice for general maintenance and repair tasks handled by HVAC technicians, plumbers, maintenance mechanics, and experienced handymen. Typical applications include door hardware, screen door closers, light-duty tensioning assemblies, and similar mechanical linkage systems where a compact extension spring with predictable load characteristics is required. The nickel-plated coating adds resistance to moisture and mild corrosive environments, extending service life in exposed locations.

Installation Notes

Extension springs store energy under tension and should be handled with care during installation and removal. Relieve all tension from the assembly before disconnecting or connecting the spring. Use appropriate pliers or hook tools to seat the single-loop ends onto mounting pins or hooks without overstretching. Do not exceed the rated maximum safe load of 46.2 pounds during service.
