Garage Door Extension Spring

This extension spring is built for residential garage doors that are seven feet high and weigh 120 pounds. It serves as an authorised replacement for Stanley Hardware stock number S730-620. The spring is finished in black with a smooth surface. Homeowners and installers can use it to restore proper door balance.

Included Safety Cable

A safety cable is supplied in the package and must be installed through the spring during fitting. The cable is designed to contain the spring if it breaks, reducing the risk of injury or damage. Following the supplied instructions is essential before starting any work. The accessory changes the installation from a bare spring to a safer assembly.

Maximum Stretch Limit

The spring has a relaxed length of 25 inches and a maximum safe stretched length of 67 inches. Exceeding this limit can cause permanent deformation or failure. Installers must verify that the door travel stays within this range. Doors heavier than 120 pounds or taller than seven feet fall outside the rated capacity.
