Garage doors use either extension springs (on either side of the track, often used on lighter doors), or torsion springs (typically one or two along the wall above the door opening for heavier doors).





A well-designed spring system counterbalances your garage door. The correct spring system required for safe and consistent equilibrium of your Clopay garage door is predetermined by our engineers and shipped with your door.


Clopay spring systems are considered among the best in the industry. Here are some things to consider when comparing the safety of garage door springing systems.

Clopay strongly recommends that only a trained garage door professional install standard torsion springs. Standard extension springs can also be tricky. If you choose to install extension springs on your own, carefully follow the instructions included with your garage door. Click here for installation manual.

Clopay's EZ-SET® Spring Systems are designed to simplify the garage door installation process for do-it-yourselfers who have the confidence, tools and experience to tackle a project of this nature. EZ-SET Spring Systems include the EZ-SET Extension Spring System and the EZ-SET Torsion Spring System. EZ-SET is safer and uses common tools (3/8" drill) for installation versus the specialized tools required for standard spring systems. Both EZ-SET systems include an installation how-to video.






Clopay extension springs come with a safety containment cable system that spans the entire length of the spring and prevents loose ends from causing damage or injury. If your garage doors have extension springs, be sure they utilize a safety containment cable.

Torsion springs are mounted on a shaft that acts as a containment system for that specific type of spring system.



Many injuries occur when unqualified do-it-yourselfers attempt to remove or adjust the bottom bracket that connects the lifting cables to the spring system. This bracket is under extreme pressure. If it becomes loose, it can separate from the garage door's overall structure and cause injuries or property damage. Clopay's patented Safe-T-Bracket™ cannot be removed under normal circumstances until after the spring tension has been released.


Clopay uses corrosion resistant galvanized torsion springs on its standard size residential doors. Simply put, they are more attractive and last longer than oil tempered springs.


Standard Extension Springs

These are coiled springs installed above the door's horizontal track. Experienced do-it-yourselfer's can install these springs by closely following the installation instructions and safety warnings included with each Clopay garage door.

Standard Torsion Springs

These include a shaft, spring and drum assembly installed directly above the door opening. The torsion spring distributes the garage door's weight evenly, which is critical with a wide and/or extremely heavy door. Standard torsion springs should only be installed and removed by a trained garage door professional.

EZ-SET Spring Systems

Clopay's EZ-SET Spring Systems are designed to simplify the garage door installtion process for do-it-yourselfers. Now the most difficult task of setting the spring tension can be accomplished with a 3/8" power drill in seconds. A user-friendly 45 degree drill input angle allows the installer to stand securely on the ground instead of on a ladder. This eliminates the need to manually lift the deadweight of an unsprung door. EZ-SET comes standard on select Clopay garage doors or it can be special ordered through a distributor.

The EZ-SET Extension Spring System

Clopay's patented EZ-SET Extension Spring System is designed with the do-it-yourselfer in mind, making installation simpler and safer. Our unique system eliminates the need to manually lift the deadweight of unsprung garage doors. If you choose to install a door with extension springs, we recommend you use EZ-SET.

The EZ-SET Torsion Spring System

Once a job exclusively for trained garage door professionals, Clopay's EZ-SET Torsion Spring System makes torsion spring installation faster and easier for the do-it-yourselfer. Our system eliminates the difficult and dangerous manual winding process. And with this system there is no need to locate and prepare the center mounting pad!
