Garage Door Basics:

Track Types:

Gauge = thickness of steel
Lower is better. 24 gauge is thicker than 25 gauge.

Natural Light:
Inserting a window made of glass or an acrylic material, in one or more of the door sections allows natural light to enter the garage area.

Sections:
Panels made of fiberglass, wood, aluminum, steel or wood composite materials. The sections are installed into stiles that are connected with the use of hinges and rollers.

Bottom Bracket:
Cables and/or springs that are used to raise and lower the door are connected to the bottom bracket

Cable Drum:
The cable drum provides grooves to allow for the winding of the lifting cables on the torsion spring shaft, when opening the garage door.

Torsion Springs:
The torsion spring takes the weight of the garage door and makes opening and closing it much easier and more efficient.

Extension Track:
The extension provides a track for the rollers to run on when the garage door is opened.

Rear Track Hanger:
The rear track hanger holds the extension track in position and supports the weight of the garage door when open

Track:
The track allows the wheels on the garage door to run easily as the garage door is opened and closed.
