Door Knockers and Viewers
Knockers come in a variety of styles and finishes, generally aimed at matching letterbox and door handles. However, not all manufacturers provide finishes to match items from other manufacturers; thus depending on your specific requirements, matching may not always be possible.
A door knocker can incorporate a VIEWER if required. Or a viewer can be fitted in it’s own right. Viewers can also be fitted at low level to suit disabled users.
