  Livingston NJ-Garage Door Spring Opener Repair 

Livingston NJ- 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 Livingston NJ- Garage Door

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.

When your garage door has to be raised too high to support your garage door opener, you do not have to buy an entirely new electric opener. You can save money by simply purchasing garage door extension spring replacements and cables. The extension cables allow you to raise the garage door to heights of 7 feet or 8 feet, or you can buy full extension springs for garage doors that range in height from 78 in. to 84 in. The lightest of these springs supports balance weights of 50 lbs., while the strongest of them supports balance weights of 250 lbs.

In addition to cables and springs, you can also purchase any supporting hardware that may be required. Cable pulley wheels are very inexpensive, and if you don’t know how heavy your garage door is, you may need a counter balance lever arm to weigh it.
