What is an extension spring on a garage door?
Extension Springs They are mounted on both sides of the garage door and cables which attach the spring to the track on one and the track supports on the other. Extension springs expand and contract as the door closes and opens, as opposed to twisting.
What is the difference between extension springs and torsion springs?
Extension springs fully expand and contract when operating an overhead door. Torsion springs turn. Torsion springs are sturdier and last longer. Torsion springs do cost more, but generally last between 15,000 and 20,000 cycles, whereas extension springs last up to 10,000 cycles.
Where are the springs on a garage door?
The springs are located horizontally on a steel shaft and have cable drums at both ends. The torsion spring is mounted to the header wall above the garage door. Most commonly it has a three-pronged support system with a center and two end bearing plates at either end.
Which is better extension spring or torsion spring?
Torsion springs are sturdier and last longer. Torsion springs do cost more, but generally last between 15,000 and 20,000 cycles, whereas extension springs last up to 10,000 cycles. You can do the math on the torsion springs. It only gets better from there.
How do extension springs work?
Extension springs absorb and store energy as well as create a resistance to a pulling force. These springs are normally attached at both ends to other components and when these components move apart, the spring tries to bring them back together again.
What does the color mean on garage door springs?
The color code on a torsion spring indicates whether it is a “right wind” or “left wind” spring, with black indicating right wind and red indicating left wind. Beyond that the torsion spring is color coded so that technicians can determine the thickness, or gauge, of the wire.
Can you raise a garage door with a broken spring?
Garage doors with broken springs should not be opened. Doors in this condition can be difficult to lift because the garage door opener loses the support springs provide in lifting and lowering the door. We don’t recommend attempting to open a garage door with a broken spring but sometimes it’s an absolute emergency.
