How Many Hinges Do I Need?

The number of hinges required depends on the weight of the door. Here are some guidelines:

- For doors weighing up to 40 lbs, one hinge is recommended.

- For doors weighing between 40 and 100 lbs, two hinges are recommended.

- For doors weighing between 101 and 140 lbs, three hinges are recommended.

- For doors weighing between 141 and 180 lbs, four hinges are recommended.

- The heavier the door, the more hinges you will need. However, ensure that all hinges have the same tension when using multiple hinges on one door.

Important Instructions:

1. Adjust the tension when the door is in the closed position.

2. Regardless of whether it is a right-hand or left-hand door, always rotate the tension adjustment rod or hex wrench to the left.

3. Once you have completed the final adjustment, make sure to drive the pin flush with the hinge barrel.

Here Are Some Tips:

- These hinges come with both machine screws and wood screws, making them suitable for both 1-3/4" and 1-3/8" thick doors.

- Please note that adjusting the tension to be negative will not make the hinges self-opening.
