Choosing a Replacement Door Knocker by Center to Center Length

There are so many types of Door Knockers that it can be hard to choose just one but one determining factor--besides style--should be if you are replacing a knocker that is already installed. By choosing a door knocker with the same center to center holes, you can easily install the new knocker without having to drill more holes.

Some knockers are surface monted meaning that they screw into the face of the door. With these knockers, drilling new holes into the door is almost unavoidable. But most knockers are thru-bolt mounted where the door knocker is fastened directly to a door with bolt/s that go all the way through the door. These bolts are visible on the other side. That is where matching up the existing holes come in handy as it can be an unwanted step to patch the old holes and drill new holes for a knocker with a different center to center measurement.

There are 2 basic measurements when selecting a door knocker:
Center to Center: The lengh between the centers of the mount holes vertically.
Overall Length: The length from the top of the door knocker to the bottom.
