## Overview

The Defender Security E 2542 Door Knob Rosettes are expertly crafted stamped steel plates with a satin nickel finish, designed to fit vintage-style door knobs on square spindles.

Ideal for professionals and DIY enthusiasts, they combine classic aesthetics with reliable construction, requiring minor door prep for modern installations.

## Description

These vintage style door knob rosettes are constructed of stamped steel and come in a satin nickel 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 inside diameter of 1/16 inch, and outside diameter of 2-1/2 inch and have a 2 inch 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 inch (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.

Review: These are basic, but fantastic. The good: - Manufacturing: These are well made and consistent. I bought 6 total and they are all absolutely identical, so quality control is spot on - Packaging: These are two packs, but they are separated by a small piece of paper to ensure the don't arrive scratched. Really nice touch. Other: - Restrictive install: These require an old-style mortise hole on your doors. If your doors have modern knob-holes, you'll need to get creative. I sanded and glued 1/2" x 1/2" square dowels into my doors to give these something to screw into. The result are perfectly fitted knobs with antique flare Bottom line: I love these. With a bit of work, they can be used with any style of door, but expect that it won't be straightforward unless your doors were originally cut for antique knobs. I will absolutely buy these again in the future if I find myself needing them.
Review: Just stamped out sheet metal but works as intended. Decent product at a decent price.
