Spring Replacement

Garage door extension springs have been for years the most common  springs seen for opening a garage door. Torsion springs are used for this  purpose as well, but are a more refined and sophisticated type of spring which  is gaining in popularity. Most overhead Garage Doors feature extension springs,  but you can always request torsion springs if you want. Double automated doors  usually feature torsion springs.  

 

Extension Springs

The extension spring looks like the old fashion box spring you see in  mattresses. They are located at the sides of the door and are mounted on the  swing arms. They have a hook on each end and when purchased, they will be in  their compressed state. Because they have no protection factors when stretched,  it is the more dangerous of the two springs. It is also more inexpensive  compared to the torsion spring.

Its main difference from torsion springs is that the operation of the  extension spring is based on distance; the further it is extended, the more  force is applied on the spring. It can last from 5,000 to 10,000 lifts.

 

 

Torsion Springs

Torsion or Torque springs are twisting steel which retains the force in the  twist of the internal bar. If you think of the old fashioned mouse trap you have  the idea. The power is created by twisting the mouse trap under pressure. The  torsion spring's force is proportional to how the torque in the twist.   This is usually an enclosed unit and thus safer than the loose spring. Torsion  springs are located at the upper section of the door and are usually mounted on  the door header. This kind of spring will be the far stronger of the two and can  lift a weight up to 500 lbs. It has a lifespan of approximate 20,000 lifts.
