Selection guide
Choosing door knockers: fixing spacing and door thickness
The fixing behind a door knocker matters as much as its outward shape. For a replacement, begin with existing holes and the door construction.

What determines the choice
Compare overall knocker size, the flat area of the door and clearance for the moving part. A narrow frame or decorative profile can obstruct a model that otherwise looks suitable.
If retaining existing holes, confirm centre spacing and whether fixing access is from inside or outside. Screw length must suit the door construction. When matching the finish to numbers or other accessories, confirm the supplied colour against the product reference.
This guide brings together Door knocker 2304 and Rectangular door knocker 4160 to help you compare their application and connection details.
