Door Knocker Installation

The following instructions are a general guide to knocker installation. We have selected one of our typical knockers as an example. Other knockers may be installed using similar techniques.

Locate the center of the door.
Locate desired height of knocker and mark the top hole.
Drill top hole. The size of the hole should be the same as the shoulder of the blind nut which is 7/16". See Figure 1.
Carefully enlarge the hole on the outside of the door so it accepts the knocker post. This is done by first re-drilling the hole to match the size of the flats of the post. Finish with a sharp chisel. The knocker post in this example is 1/2"
Repeat this step for the other posts. See Figure 1.
Note: You want the knocker post to fit tightly into the door.
Insert knocker into the top hole with the rosettes in place. See Figure 2.
Mark the threaded post 1/4" shorter than the door thickness but NO SHORTER.
Cut the threaded post to length and complete installation.

Note: The blind nut should be flush with the door. The shoulder of the nut is morticed into the door.
