描述

Garage door Standard extension springs are coiled accessories installed above the door’s horizontal track. When the door is opened, the energy stored in the extended springs is used to lift the door. It is very common for this system to fall victim to frequent use, and as the door is moving up and down, the steel in the springs will weaken and eventually break.

Garage door extension springs use resistance to help a door function. They’re tightly coiled and extend and retract as a garage door operates. In general, extension springs return a moving object to its original position. Something moves, which extends the spring, and the resistance in the spring pulls the object back. That’s how garage springs work. In a garage door system, extension springs attach to pulleys and go above the door’s horizontal track. Tension in the spring then helps the door to operate.
