150lb 25” Long Garage Door Extension Springs

Take Note :

Installing springs is a professional job with certain safety risks. We recommend that you seek the help of a professional. If you choose to install them yourself, please wear appropriate protective gear and be aware of the safety hazards.

PACKING INCLUDED :

One pair of Garage Door Extension Springs, One pair of Non-Slip Gloves and Installation Instructions are included in the package, so you can start installing immediately after receiving the product.

This spring is rated for garage doors that are up to 7 feet tall.

HIGH QUALITY :

Made from professional ASTM-A228 spring steel coils that have been heat-treated to ensure they have extremely high durability. The latest electrophoretic coating technology offers excellent corrosion resistance and excellent tensile properties. Salt spray testing lasts up to 300 hours with a minimum of 16,000 cycles (a cycle is 1 open & close of the door). You NEVER need to maintain the spring and keep your hands clean during installation.

DOUBLE LOOP ENDS :

They are more sturdy than open loops, as there are two coils of the spring that connect to the eye-bolt and the pulley. We currently only  offer double looped ends as we believe this is the best replacement option available (You can replace any end type with double looped).

HOW TO ORDER EXTENSION SPRINGS:

To order the correct extension spring for your garage door,you will need to know the height and weight of your door.

SIMPLE TYPE SELECTION :

The type selection of the tension spring only needs to be based on the size of the garage door. For different garage door sizes, please refer to the table in the figure for the type of tension spring to choose.
