What Are the Different Parts of a Garage Door?

On the surface, a garage door looks like a pretty simple thing. Just another door on your property, we can all be forgiven for only thinking of the door itself, but a garage door is actually made up of a number of complex parts.

As a homeowner, you may not ever need to understand all the little intricate features of your garage door mechanism. However, if your garage door encounters a fault or you notice a part breaking, it’s going to be useful to know what the part is and how it fits into the general operation of the door. That’s why, at Doormatic Garage Doors, we’ve put together a guide to the different parts your garage door may include.

Garage Door Parts

Now let’s go through some of the common garage door parts you’re likely to find on your door and the framework around it.

Door tracks

Most garage doors will feature tracks. These will typically run vertically on either side of your garage door opening. The door sits in these tracks, using them as guides for a smooth and even opening action.

Bottom rail

The bottom rail – sometimes called the bottom seal or weather strip – runs horizontally along the bottom of the garage door itself. When lowered, it creates a seal with the floor to prevent rain and debris from flowing into your garage. If this rail is damaged or if your floor is uneven, the seal will not work.

Hanger kit

If you have a garage door suspended under the ceiling of your garage, you’ll likely have a hanger kit — usually a metal, triangular frame. This holds the rails in place and can also be used to hold any motor in place for an electric garage door.

Rollers

Almost all garage doors will feature rollers along the side for smooth operation. These sit inside the tracks and roll up and down, guided for a seamless action every time.

Garage door hinge

If you have a garage door that is formed of numerous sections, you will find each section is joined to the next with hinges, allowing the door to bend when opening and closing.

Pulley and cable 

Key to the lifting and lowering of your garage door, the cable is attached to your springs, while the pulley wheels help to lessen the weight of the door itself. This combination is what makes it easier to lift and lower the door.

Torsion spring

Many garage doors feature a torsion spring, twisting to hold energy, and counteracting the weight of the door for its safer operation either manually or with a motor.

Cable drums

A cable drum is similar to a pulley, but is wider to allow for more of the cable to wind around it.

Garage door chain or belt

Some garage doors will use a chain or belt to aid with the lowering and lifting of a heavy door. This is usually paired with a drive mechanism.

Curved door arm

In some up and over garage doors, a curved door arm will attach the top of the door itself to a rail running in the centre of the garage just underneath the ceiling.
