Designed for indoor use, it fits square drive spindle systems common in antique doors and adjusts to various door thicknesses. The set includes mounting hardware and set screws for secure installation, making it a perfect blend of classic aesthetics and reliable functionality. ## Description These vintage style door knobs are constructed of steel and come finished in a bright brass plating. 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's model number 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. ## Features - VINTAGE INTERIOR DOOR KNOBS: This closet door knob set is designed for indoor use only; this classic style knob set fits square drive spindle systems commonly found in antique and vintage door hardware sets - ADJUSTABLE DESIGN: The door knob replacement set can adjust to accommodate different door thicknesses - DURABLE & STYLISH CONSTRUCTION: These vintage style door knobs are constructed of solid brass with a steel spindle; the door knob set comes in a bright polished-brass finish - EASY TO MOUNT: Mounting hardware is included with the closet door knobs; the shanks on these closet knobs include 2 set screws per shank for fastening the knobs to the square spindle; use a small dab of midgrade glue on the threads to keep handle in place - DIMENSIONS: The brass door knob features 2-1/4 inch outside diameter knobs with 1-3/4 inch projection and 17/64 inch x 3-1/2 inch square spindles; please refer to the line art drawing for dimensions and compare to your needs before purchasing - COMPLETE SET INCLUDED: This pack of 2 door knobs includes steel spindle with 3/8 inch -20 threads and set screws for secure installation on square drive spindle systems - COMPATIBILITY NOTE: This item is designed for traditional door configurations and requires separate purchase of mortise lock body, door rosettes, trim and strike plates, or latch and fasteners for complete installation ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0000CBIQC | | Additional Features | Easy to Install | | Best Sellers Rank | #14,366 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #85 in Door Knobs | | Brand Name | PRIME-LINE | | Color | Brass | | Customer Package Type | 1 | | Customer Reviews | 4.4 4.4 out of 5 stars (531) | | Exterior Finish | Brass | | Finish Types | Brass | | Global Trade Identification Number | 00049793022806 | | Handle Attachment Mechanism | set screws | | Handle Compatibility | Application Specific | | Handle Material | Alloy Steel, Brass | | Handle Type | Knob | | Included Components | Door Knobs | | Indoor Outdoor Usage | Indoor | | Item Depth | 5 | | Item Dimensions L x W | 2.25"L x 1.75"W | | Item Type Name | Door Knobs | | Item Weight | 5 ounces | | Lock Type | lock_type | | Manufacturer | Prime-Line Products | | Manufacturer Part Number | E 2280 | | Manufacturer Warranty Description | Goods are warranted against manufacturing defects for 1 year. | | Material Type | Alloy Steel | | Metal Type | Alloy Steel, Brass | | Model Number | E 2280 | | Number of Items | 1 | | Projection Distance | 1.75 inches | | Room Type | room | | Shape | Square | | Specific Uses For Product | Door | | Style Name | Traditional | | Theme | Christmas | | UPC | 015231886934 049793022806 | | Unit Count | 1 Count | ## Product Details - **Brand:** PRIME-LINE - **Color:** Brass - **Material:** Alloy Steel - **Product Dimensions:** 2.25"L x 1.75"W - **Style:** Traditional ## Images ![Prime-Line E 2280 Solid Brass Vintage Door Knob Spindle Set, 2-1/4 In.
