  • Our take on the 150 lb. Garage Door Extension Spring- 8' Door

    This is a single extension spring for an 8-foot-high sectional garage door, rated at 150 lb of pull and coded red under the Dasma color system. It is wound from spring wire, has double-looped ends, a 1.254 in inside diameter and stretches from 27 to 48 inches. It is rated for a minimum of 10,000 cycles, which is the low end for extension springs; better-rated springs last longer. It suits a do-it-yourselfer replacing a matched pair on a standard 8-foot door, but the spring must match the door's weight and the other spring on the same door.

    Pros
    • Rated 150 lb pull for an 8-foot door

    • Double-looped ends for secure hanging
    • Stated 10,000-cycle minimum rating
    • Standard 1.254 in inside diameter fits common hardware
    Cons
    • 10,000 cycles is a low rating versus longer-life springs

    • Extension springs store high tension and need safety cables
    • No included safety cables or instructions

    Questions and answers

    Does one order include both springs?
    It is a single spring. Most doors use two, so buy a matched pair and replace both at once.
    How do I know it fits my door?
    It is made for an 8-foot-high door with a 150 lb pull per spring. Check your door's weight and the color code on the old spring; red is the Dasma code for this rating.
    How long will it last?
    The maker rates it for at least 10,000 cycles. A cycle is one open and close, so daily use adds up quickly; higher-cycle springs last longer.
    What size is the spring?
    The inside diameter is 1.254 inches and it stretches from 27 to 48 inches. Match the length and diameter to your existing spring and hardware.
    Do I need safety cables?
    Yes. Extension springs should be run through safety cables so a broken spring cannot fly loose. Cables are not included.
