Garage Door Tracks

For the door to operate optimally, it needs a specific guide that moves it in the intended direction. The function of the track is similar to the railway tracks. They are designed to ensure the garage-door moves in the right direction. Inside the tracks, you will find rollers that guide the door when it is being raised or lowered. This component is made of steel and comes in both standard and non-standard heights; this is meant for low garages.

This component is only fitted to garage-doors using torsion springs. When using other types of springs, you may not need to add the tube shaft.

Garage Door Cables

Lifting cables are fixed vertically from the top of the door to the bottom connecting the bottom of the door to the drum fitted at the top. These cables connect the force from the spring to the door that eases lowering and raising the garage doors.


This component is responsible for stabilizing the door and keeping the cables taught to hold the entire garage door system perfect equilibrium. Fitted at both ends of the torsion bar, they work by spinning when the door is either raised or lowered, rolling up the cables, or spooling them out.

Garage Door Rollers

As discussed previously, rollers are found inside tracks and move smoothly when the door is raised or lowered. Most rollers are usually made of nylon and steel, with most homeowners attributing the garage door noise to the material used in the rollers’ manufacture.

The Garage Door Opener

Most households in the USA are currently switching to electric openers. This is the most complicated part of the door that requires a power source and a computerized system inside it to work.
