It can be difficult to find a new door knocker with the same BC dimension. Especially if the original one has been there for many years. There is no standard for the BC dimension. The BC for the most part is determined by the design of the knocker. The mounting lugs used to attach the hardware are usually placed at a thicker portion of the casting. This is to give them more strength. Sometimes you have to settle for a replacement that is close. If the two BCs are within 1/4 or 3/8 inch of each other you can usually enlarge the holes in the door a bit to make the fit. If you are lucky the existing mounting hardware will cover the enlarged holes.

Urn door knockers can be found that are mounted to the door by one of two methods. One method uses screws that pass through the knocker and screw into the door. The other method uses bolts or other hardware that goes entirely through the door. Either method works well on wooden doors but the through the door method works best on other doors. It seems that I have answered my own question. The urn door knocker is popular for many good reasons the least of which is that they really look great on the entrance way to a home. The selection of a door knocker may be a bit more difficult than you imagine.

The holes being small due to smaller diameter mounting hardware is easily fixed with a drill. If the holes are to far apart or to close this is another matter. The distance between the holes is called the Bolt Center or BC dimension. There is a reason for this seemingly odd name. You want the bolt to go through the center of the hole so this is the point that you would mark the door to be drilled. The problem you run into when replacing an existing door knocker is the holes are already drilled through your door. On the outside the holes can be covered by the knocker itself but on the inside they are exposed.
