1. What is a Spring Hinge?

Spring hinges are a continuous or butt type hinge with a knuckle or knuckles removed and replaced with a torsion spring. They are available in two versions: the spring legs push the leaves apart, or the spring legs push the leaves together.

It is common to refer to a spring hinge that has the spring legs pushing the leaves apart as spring-loaded-to-open and a spring hinge that has the spring legs pushing the leaves together as spring-loaded-to-close. Neither description should automatically refer to how the hinge is going to act in the application as that is dependent on how the hinge is mounted to the door or cover.

When designing your spring hinge into your application, it’s important to see which direction the spring is pushing your hinge leaf after it is mounted to the door. That action determines whether you want a hinge that is spring-loaded-to-close, pushing the hinge leaves together, or spring-loaded-to-open, pushing the hinge leaves apart. See our YouTube video below for a visual explanation of the loaded to open and closed spring hinges.

Applications where the hinge mounting causes the spring legs to be between the hinge leaf and the door or frame work much better if the hinge leaves are embossed to hold the spring leg. See here for more information on the embossing operation: Custom Spring Hinges - Springs Embossing

Once you’ve decided on the style of spring hinge your application requires, you’ll next decide on the tension or strength. This describes how fast or how much weight the spring hinge will move. The strength can be increased by either a stronger or thicker wire spring or by having multiple springs installed in the hinge.

We have many stock spring hinges and the best way to determine the correct spring hinge for your application is to select a sample or two with a torque close to what you calculate what you need. You can then try the sample in your application and see if you need more or less torque. You can then fine tune what you need with either a different item or maybe multiple spring hinges.

Custom spring hinges are available but we recommend exhausting our standard parts first. Delivery is much faster and cost is usually much lower.

What is a spring hinge?

A spring hinge is typically a regular hinge with at least one knuckle removed and replaced with a torsion spring. The spring legs apply pressure on the hinge leaves to move them.

What types of spring hinges are there?

There are two main types of spring hinges; Spring-loaded-to-close hinges have a spring that pushes the leaves together to the hinge closed position. Spring-loaded-to-open hinges push the leaves apart to the hinge open position.

In a spring hinge, what is the difference between Spring loaded to close and Spring loaded to open?

Though the hinges may look the same, the difference is whether the spring legs push the leaves to the closed position or to the open position.

I need my spring hinge to open my door when it is unlatched, should I use a hinge that is spring-loaded-to-open?

The action of the door is not necessarily the same as the type of spring hinge you use. You need to analyze your application and see which direction the leaves will be pushed by the spring after the hinge is mounted.

Can I get a spring hinge in a custom strength?

In most cases yes. You would need to know the exact spring torque and dimensions for a spring manufacturer to analyze and see if it could be made. It's also recommended to use a standard stock spring hinge and see if multiple hinges could satisfy your application.

How do I specify the torque for my spring hinge?

There are ways to calculate the torque of a spring hinge but with the friction of the spring and hinges when assembled, the calculated torque is not correct. Maybe only a starting point. We suggest you try some of our standard spring hinges to get close. Many time you will find that one of our standard parts work. If not, you can have us provide a samples until we get your application right.

What materials are spring hinges typically made from?

You will find spring hinges mainly in steel, stainless steel and aluminum with some fancy ones in brass, bronze or other materials. Finishes can also be done, but care should be taken that the spring legs have free movement after any surface treatments. Torsion springs are typically made in steel or stainless steel.
