Thank you for the quick service. I sent an online request for garage repair, and within 10 minutes your company called me back. I booked a technician same day, and he came prepared with his truck fully loaded with the parts needed to fix my door. The technician was friendly and knew everything he needed to know about garage doors. Terrific service! I will definitely use your services should anything else go wrong.
The torsion springs on steel rolling doors work the same way as other torsion springs in the garage door industry. When the door is closed, the spring is wound. The spring is secured to a spring anchor bracket on one end and to the shaft on the other. When the steel rolling door opens, the spring in the barrel supports most of the door weight. The remainder of this weight is lifted by the chain hoist or the operator.
Since their invention in the 1920s, electric garage door openers have come a long way. Garage door openers work by using a trolley connected to an arm that attaches to the top of the garage door and slides back and forth on a track, which opens and closes the garage door. When operating the motor, a chain or belt turns and pulls the trolley along the track. A good garage door opener will have a horsepower of 1/2 HP, 3/4 HP, or 1-1/4 HP. Garage door openers have the ability to open and close a limited number of times in power outage emergencies. Security is something else to consider when purchasing an opener. It's helpful to have sensors that will stop the operation of the garage door when a person, vehicle, or other obstacle is in the way.
Garage door springs come in two styles: torsion (see above), which mounts on the header above the door, and extension (Photo 1), which floats above the upper roller track. In the past, extension springs were safer to install but didn’t have containment cables running through the center of the spring. Without cable, these springs become dangerous, heavy whips when they break. They also tend to be noisier than torsion springs, and we recommend you use them only if you don’t have the 12 in. of headroom above the door that a torsion spring requires.
The Phone App: A basic, functional, app with a few frills. It works well enough though some settings are best changed on the web site (that I didn’t know about). When installing the smart hub your phone will need to be on your 2.4ghz wireless network to complete the setup. After that, it doesn’t matter what your phone is connected to - your home network or a cell connection. The system can be setup entirely from your phone. I set up an open alert, a close alert and a 10pm door not closed reminder. The alerts can be sent to you via Text or email.
