Extension vs. Torsion: Is One Garage Door Spring Better Than the Other?
Garage door springs play a central role in maintaining the door’s functionality. They come in two categories—torsion and extension springs. The two springs are very different, but does that mean that one type is superior to the other?
This article will list the differences between torsion and extension springs and determine if either one is more beneficial.
What are the main features of torsion springs?
Torsion springs come with a metal component on each end. These ends are also known as cones, and one of them has a little indentation. The purpose of the indentation is to fit a winding bar used to crank the spring.
The other end of the cone is connected to a metal plate called the center bearing. This one doesn’t have a hole for a winding bar, which is why it’s also known as the stationary cone.
Garage doors with this system have one or two springs. Generally, one torsion spring is used for single garage doors, whereas a double garage door requires two springs. However, if a single door is too heavy, two torsion springs may be necessary.
Regarding their durability, torsion springs typically last longer than extension springs. They require fewer adjustments and parts, meaning that they’re not demanding maintenance-wise. Finally, even if they break, they are usually far less dangerous than the other spring model.
The downside is that torsion springs are generally the costlier option.
What are extension springs?
The distinct feature of extension springs is the loops on the ends. Depending on the weight of the garage door, the loops fall into three categories:
Single loop—This loop is the most affordable solution. It doesn’t complete a full circle, which is why it’s the weakest loop type. As such, it’s only suitable for lightweight garage doors.
Double loop—Springs with a double loop make a full circle. For this reason, they are more durable and can hold mid-weight doors.
Clipped ends—The last type is the strongest version and can be used for heavyweight doors.
As mentioned in the previous section, there are several problematic areas with extension springs. First, they use a lot more components that are prone to breakages. They also need to be fastened with safety cables to prevent them from becoming projectiles in case of a failure. Lastly, they have a shorter lifetime and support less weight, even with clipped ends.
On the other hand, extension springs are a cost-efficient garage door spring solution.
Final thoughts
Considering all these features, it’s clear that torsion springs are a much better option. They feature superior durability, lower maintenance, and don’t pose a serious threat when they break. Therefore, if the budget allows it, there’s no reason to think twice about mounting torsion springs to the garage door.
