Prime-Line Polished Replacement Knobs Right or Left Handed

These vintage style door knobs are constructed of SOLID BRASS and come in a bright polished-brass finish. This set of knobs is designed for indoor use only, and it includes a 17/64 in. x 3-1/2 in. steel spindle with 3/8 in. -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 2 set screws per shank 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, door rosettes, trim and strike plates, or the latch and fasteners. For brass plated stamped steel knobs, kindly see Prime-Line's model number E 2280. 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. These knobs are constructed from solid brass. They feature a 9/32 in. square spindle shaft. This style knob fits on old style bit key lock systems.
