Door Knockers Center to Center

Replacing an existing door knocker? The easiest installation is finding a new knocker with the same center to center hole spacing as your current one — no patching old holes or drilling new ones required.

Most knockers are thru-bolt mounted, meaning the mounting bolts pass all the way through the door and are visible on the inside. Matching the center to center measurement lets you reuse the existing holes for a clean, easy swap.

2 key measurements

Center to Center: The distance between the centers of the two mounting holes, measured vertically.

Overall Length: The full length of the knocker from top to bottom.
