Garage Door Extension Springs
Extension springs for garage doors are manufactured for specific door heights. A 7-inch high garage door, for example, should have the right size of extension springs to make the doors function properly. If there’s a mistake in the product choice, there is a huge tendency that the door won’t close. The pulley system of the springs allows them to stretch up to ½ of the door’s height. For an 8-inch door, the stretch is 27 x4 8, wherein 48 is the difference between the length of the spring when it is closed or opened. The 27, on the other hand, refers to the spring length when it is compressed.

It is also wise to seek professional assistance when it comes to installation and repair. Extension springs are very difficult to choose and install, and may require the services of experienced technicians. The calculation of spring length is also necessary to make the choice easier for homeowners. Inspection is important when early signs of wear and tear are visible. The springs may just need repair, which actually saves a lot of money compared to having them replaced fully.
