These vintage style door knob rosettes are constructed of stamped steel and come in a chrome plated finish. This type of rosette is designed for indoor use only, and it is used with other vintage style hardware by Prime-Line Products and other classic hardware manufacturers. These rosettes feature an outside diameter of 2-1/4 in., an inside diameter of 11/16 in. and have a 1-3/4 in. mounting hole center spacing. Note: If attempting to use these rosettes on doors with large, pre-drilled knob holes, the fasteners of these rosettes require a solid surface to mount to. The large 2-1/8 in. (approximate size) pre-bored holes must first be filled with a hardening filler, to then be able to receive the rosette fasteners. Installation tip #1: Products like Fix-It-All and Bondo Body Filler have worked well for some, but care must be used to avoid damaging any prefinished door surfaces during application and finishing. Installation tip #2: Apply a small amount of Loctite ThreadLocker 271 to the set screw threads in the event they are loosening - Loctite purchased separately.
