The Rockwood 614V.15 cast brass door knocker has a built-in door viewer and a satin nickel plated clear coated finish (ANSI/BHSM number US15/619). There is a space for engraving a name or number. The knocker with viewer meets American National Standards Institute (ANSI) A156.16 specifications. It measures 3" high x 2-1/8" wide x 0.45" thick, and it includes two #8-32 x 2" flathead machine screws and two #8 finish washers for attaching the knocker to standard 1-3/4" thick doors.

Door viewers, also called peepholes, consist of a lens and cylinder which is inserted into a door, allowing a view outside. The amount of visibility is determined by the degree of the lens; the higher the number, the greater the visibility. Door viewers are sometimes incorporated with door knockers.
