Overhead door parts includes the torsion springs, extension springs, rollers, track, angles, hinges, bottom brackets, top brackets, lift handles, bottom seals, jamb brackets, cable drums, spring fittings, cables, locks, etc. Garage door parts can be bought on line. Though you can easily install them without needing a professional, but for safety reasons it is better that it is fitted by a professional. This also ensures that they are fitted correctly.
Brackets can be in different forms. There is a quick close fixture brackets that can reduce headroom requirements by 1-1/2” to 2-1/2”. Thus, allowing it to solve headroom problems when installing garage door openers. This is also the most common and the most cost effective way to solve low headroom problems for automatic garage door opener. They are used at initial installation and can be added to existing installations. There is also a low headroom bracket.
This is used exclusively for residential and extension spring doors with a height of 8’. This type of door won’t go higher than the top of the spring shaft when the door is opened. No modifications to the door or track are needed with this type of bracket. Similar to the close fixture brackets, this can also be used at initial installation and can also be added to existing installations.
The low headroom bracket is installed through the removal of the top fixture and attaching the low headroom bracket in its place. This is designed to operate an extension spring door in a minimum of 7” of headroom. But with this type of bracket, you will need to cut and remove portion of the vertical track before installation to achieve full headroom clearance.
Springs, one of the many overhead door parts used in garage doors are used to help raise and lower the door safely. There are two types of springs used in garage doors. There is the extension spring and the torsion spring. Extension springs are springs that are attached on either side of the door and stretch along the horizontal part of the track when the door is closed.
On the other hand, torsion springs are found at the top section of the door and are mounted to the header. This type of spring is a wound spring and do not expand or contract when the door is moved. But this is also a better spring as it offers more safety to the homeowner and better balance to the door. Overhead garage doors with single car door have extension springs as part of the standard hardware but the torsion spring is only available upon request. While garage doors with double car doors are made with torsion springs.
Another part of your garage doors is the hinges. This is an essential part of your garage door as they ensure that the door functions properly. A professional, to ensure that they are properly working and aren’t going to break anytime soon, should regularly check the springs and the hinges. I hope this post has helped explain overhead door parts a little better.
