## Overview

The Prime-Line E 2499 is a solid brass vintage-style door knob spindle set featuring a 2-1/4 inch outside diameter and a bronze finish. Designed for indoor use, it fits square drive spindle systems common in antique doors and adjusts to different door thicknesses. Constructed with durable brass knobs and a steel spindle, it includes mounting hardware and set screws for secure installation. Perfect for restoring classic interiors, this knob set combines authentic style with reliable performance.

## Description

These vintage style door knobs are constructed of steel and come in a classic bronze finish. This set of knobs is designed for indoor use only, and it includes a 17/64 inch x 3-1/2 inch steel spindle with 3/8 inch -20 threads. This classic style knob set fits square drive spindle systems commonly found in antique and vintage door hardware sets, and it can adjust to accommodate different door thicknesses. The shanks on these knobs include set screws for fastening the knobs to the square spindle, but it does NOT include any of the following components and they must be purchased separately: The internal mortise lock body, the door rosettes, the trim and strike plates, or the latch and fasteners. For solid brass knobs, kindly see Prime-Line part E 2297. Note: This item cannot be used on pre-bored doors that have large, newer style door knob holes without first prepping them to receive this hardware. Installation tip #1: Because the fasteners of the rosettes (purchased separately) require a solid surface to mount to, the large 2-1/8 inch (approximate size) holes must first be filled with a hardening filler, to then be able to receive the rosette fasteners. 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: Works GREAT - I bought an old house with old interior doors and one door had no knobs. All the works were there but just no knobs. So I had to always leave the door open because if it closed I couldn't open it. This was a closet door so I could 'nt keep the curious cat out of it. I finally searched desertcart for an answer. I am beyond thrilled with these knobs- they have an old fashioned look and were so easy to install. Just remember to loosen or remove the tiny screw so you can adjust the knob onto the steel shaft- the re-tighten the screw. Thank you desertcart - I love these knobs and the cat is now kept out of the closet.
Review: Easy DIY repair - This was a very easy DIY repair! I have a hundred year old house and this was the easiest repair yet. This fit perfectly, and was the perfect replacement size. It was so easy to do, it’s a high quality knob, and it works!!

This was a very easy DIY repair! I have a hundred year old house and this was the easiest repair yet. This fit perfectly, and was the perfect replacement size. It was so easy to do, it’s a high quality knob, and it works!!

### ⭐⭐⭐⭐ Price Point: The cost is on the higher side compared to more modern alternatives.
*by H***D on June 19, 2024*

I recently purchased the Solid Brass Vintage Door Knob for my home renovation project, and I am quite pleased with the product overall. Pros: Elegant Design: The vintage aesthetic of this door knob adds a touch of classic charm to my interior decor. The intricate detailing is beautifully crafted and gives an authentic antique feel. High-Quality Material: Made from solid brass, this door knob feels substantial and durable. It has a nice weight to it, which adds to the overall quality impression. Smooth Operation: The knob turns smoothly and the mechanism feels reliable. There were no issues with the installation process, and it fits perfectly with standard door setups. Cons: Minor Finish Imperfections: While the overall appearance is stunning, there were a few minor blemishes on the finish. These are not immediately noticeable but slightly detract from the otherwise perfect look. Price Point: The cost is on the higher side compared to more modern alternatives. However, given the quality and aesthetic appeal, I believe it's a worthwhile investment for those looking to achieve a vintage look. In conclusion, the Solid Brass Vintage Door Knob is a beautiful and sturdy addition to any home with a classic or antique decor style.
