With a 2-inch outside diameter, these knobs feature a stunning fluted glass design and a chrome-plated finish, making them an ideal choice for vintage or antique-style doors. Installation is straightforward, and the knobs are made from durable materials, ensuring both beauty and longevity. ## Description Product Description If your door knob set is acting up or broken, this E 2328 Mortise style fluted glass door knob set is the perfect choice for updating and fixing hardware on interior doors. With a beautiful and classic fluted glass and chrome finish, it’s the perfect choice for your antique or vintage interior doors. Installation is a breeze, and the glass door knob set features 2” outside diameter knobs. These door knobs are for interior use only, and includes a 17/64 in. x 3-1/2 in. steel spindle with 3/8 in. -20 threads. This classic style door 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 diecast base on these knobs include the 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 matching rosettes and latch see Prime-Line’s model numbers E-2439 and E-2440. 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 in. (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. From the Manufacturer These knobs are constructed from glass and feature a chrome plated base. The knobs have a projection of 1-15/16 in. and a 9/32 in. square spindle. Easily fits on doors that are 1-3/8 in. thick. ## Features - FLUTED GLASS KNOB SET - The E 2328 fluted glass door knob set is ideal for replacing or updating interior door hardware.

Easy to install. But one came missing a screw so I have to go find one or wait. ### ⭐⭐⭐⭐⭐ Impressive Quality and Great Looks *by M***N on Reviewed in the United States 🇺🇸 on June 30, 2021* In the process of doing renovations to our Art Deco condo and looking for something to replace two walk-in closet door knobs. We needed two additional crystal type knobs to put in an entranceway closet we were adding and decided to take two originals from the interior side of the walk-in closet doors and replace with these. The reason to do it this way was to save a few $. The original door knobs are $125. Figured put these on the interior side of the closets where no one would noticed we were been cheap and the other (original) ones where they would be in plain view. Pretty crafty and frugal at the same time...eh? Well, surprise, surprise. These are fantastic looking. They are just as nice as the originals. In a million years you would never think these are less than $20. We paid $12, but I see the price has since gone up to $15. Not a biggie because they are still a screaming bargain. i can't find anything wrong with these and I am a perfectionist. They've been installed now for two months with no problems. Will update should issues occur. ### ⭐⭐⭐⭐⭐ Great value, easy to install *by S***R on Reviewed in the United States 🇺🇸 on October 4, 2022* Nice heavy glass, easy to install. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/1234312-defender-security-e-2328-mortise-style-fluted-glass-door-knobs](https://www.desertcart.ph/products/1234312-defender-security-e-2328-mortise-style-fluted-glass-door-knobs) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-05-26*
