For optimal performance, door hinges are typically installed 5"-7” from the top of the door and 10”-11” from the bottom. If additional hinges are needed, ensure they are spaced evenly between the top and bottom hinge. Always refer to the manufacturer’s instructions for proper installation guidelines.
Tendency FAQs
Our dedicated customer support team is here to help you with any questions or issues you may have.
1. Where should I install door hinges?
2. How many hinges does a door need?
A general rule is to use one hinge for every 30” of door height. For a door that is 60” tall, two hinges are sufficient. For doors between 61”-90”, three hinges should be used, spaced evenly. Using the proper number of hinges prevents undue stress on the doorframe, which can lead to damage over time.
3. Are door hinges reversible?
Most of our door hinges are reversible, meaning they can be used on both left-hand and right-hand doors. However, certain specialized hinges are designed for a specific door type. Always verify that the hinge type matches your door’s requirements.
4. What is a non-removable pin hinge?
Non-removable pin hinges are designed for exterior doors where security is a priority. These hinges feature a pin that cannot be removed, preventing unauthorized removal of the door. This is particularly useful for doors where security concerns are high.
