Prime Line Products Sp 9677 Extension Spring 1.25 in Od 3 Pack

Product Description

The PRIME LINE PRODUCTS SP 9677 is a double loop closed extension spring built for reliable tension and return force in a wide range of hardware and mechanical applications. Constructed from durable spring steel with a nickel-plated finish, these springs resist corrosion and maintain consistent performance under repeated cycling. The 1.25-inch outer diameter and 6.18-inch deflection length make them well suited for medium-duty residential and light commercial uses. Each package contains 3 springs, giving technicians and tradespeople a ready supply for common repair and replacement tasks.

Extension springs like the SP 9677 are commonly installed in screen doors, storm doors, cabinet hardware, small gate assemblies, and general household mechanical linkages. The double loop closed end design provides secure attachment points and even load distribution across the spring body. These springs are a standard choice for handyman contractors, maintenance technicians, and facilities personnel working through routine hardware repairs or equipment servicing where a reliable tension element is needed.

Installation Notes

Extension springs store energy under tension and should be handled with care during installation to avoid sudden release. Always wear eye protection when stretching or hooking extension springs. Use appropriate pliers or spring installation tools to seat the loops onto anchor points without overstretching. Verify that anchor hardware is rated to handle the intended spring load before completing the installation.
