What is a piano hinge, and why might I need to cut it?

A piano hinge, also known as a continuous hinge, is a long hinge that runs the entire length of two surfaces to which their rotation is relative. These are most common in piano lids, hence the name. But at IHINGES, we specialize in producing these types of hinges for industrial use.

Our piano hinges are extensively used in various industrial equipment doors such as industrial ovens, large sheet metal boxes, environmental test chambers, climate test chambers, network cabinets, electrical boxes, railroad equipment, medical equipment, military equipment, and more. Given their extensive applications, there’s often a need to cut these hinges to fit specific equipment sizes.

What do I need to cut a piano hinge to size?

Cutting a piano hinge to size requires some specific tools. These include a measuring tape for accurate measurements, a metal hacksaw to cut through the hinge, a file to smooth out any rough edges left from the cutting, and a punch and hammer to remove the pin.

How do I cut a piano hinge to size?

After you have gathered all the necessary tools, follow the steps below carefully:

  1. Measure: Start by measuring the length you want to cut. Use your measuring tape and make a clear mark where you want to cut.
  2. Remove the pin: The next step is to remove the pin from the hinge. This can be done using the punch and hammer. Place the punch on the bottom of the hinge pin and gently hit it with the hammer until it comes out.
  3. Cut: Once the pin is out, use the hacksaw to cut the hinge at the mark you made. Ensure you make a clean and straight cut.
  4. File: After the cut, there might be some rough edges. Use the file to smooth out these edges.
  5. Replace the pin: Once you’re done, put the pin back into the hinge.

Remember to always practice safety precautions when handling these tools.

What should I consider when cutting a piano hinge?

When cutting a piano hinge, there are certain factors to keep in mind. First, measure twice before making a cut. You want to ensure the accuracy of your measurements.

Secondly, consider the hinge’s application. You don’t want to cut too much off if it’s meant to support a large, heavy door.

Finally, be patient and take your time. Rushing through the process could lead to a messy cut or even injury.



In conclusion, yes, you can cut a piano hinge to size. It’s a simple process that requires the right tools and precision. Just remember to measure twice, cut once, and always prioritize safety.
