The Benefits of Hinges

Extended Lifespan: Investing in hinges for your garage door pays off in the long run. Using high-grade materials ensures that rust, corrosion, and wear are kept to a minimum over time. It could mean years of reliable performance without needing replacement or garage door repair service.

Smoother Operation: Hinges provide a quieter operation than regular ones. They allow smoother, less disruptive control when the door opens and closes. That benefits households living close to other homes, which can be disturbed by loud noises from a faulty door.

Improved Safety: Hinges enable the doors to open securely from both sides. That prevents trapping people inside or outside due to defects in components or bad installation. Tough steel with anti-theft measures can add an extra layer of security against unauthorized intruders. Thus, it offers a safe environment while allowing easy access when necessary.

Increased Value: Investing in good hinges keeps your residence's value stable. It also amplifies it by ensuring it stays spotless and functions perfectly for a long time.

Hinge Function

Hinges are used to connect different parts of a garage door together, as well as to support the rollers that allow the door to move. These hinges are usually identified by a number, which indicates the specific area of the door that they are designed to support.

For residential garage doors, these numbers range from one to five, while for commercial garage doors, the numbers range from six to ten. It is generally a good idea to replace both the hinges and the rollers at the same time, as the hinges and rollers work together to support the movement of the garage door. The hinges in the center of the door are typically numbered one, while the hinges on the edges that hold the rollers are numbered based on their position on the door.

The rollers inside your garage door should have rounded edges that fit perfectly with the radius of these hinges. If they're damaged or old and rusty, you'll need to replace them.

Hinge Numbers Mean

All hinges are assigned a special stamped number that identifies both the roller carrier height and where they are to be installed on your garage door.
Sectional garage door hinges are identified by numbers 1 through 12. Residential hinges are available in numbers 1-5 while commercial hinges are available in 1-12. Residential hinges can accommodate up to 12ft tall doors (6 panels) in height. For doors over 12ft tall commercial gauge hinges must be used.

Q: What are hinges?

Q: How do hinges work?

A: Garage doors are usually made up of multiple sections that are connected by hinges. As the garage door opener lifts the door, the hinges allow the sections to pivot and fold upward. This motion is what makes it possible for your garage door to roll along its tracks and open smoothly.
The hinges help distribute the weight of the door evenly across the structure, which reduces the strain on other parts like the rollers and springs. This reduces the risk of damage or wear on the more delicate components and prolongs the life of your door.
