Emtek 5112OCTUS19 Passage Set Octagon Knob Flat Black

Product Description

The EMTEK 5112OCTUS19 is a passage set combining a Modern Rectangle rosette with an Octagon knob in a Flat Black finish. Passage sets are non-locking door hardware used for hallways, closets, and other interior doors where privacy is not required. This set fits doors ranging from 1-3/8 to 2-1/4 inches thick and requires a standard 2-1/8 inch bore prep. The standard latch is configured for a 2-3/8 inch backset, with a 2-3/4 inch backset available if specified. The set ships complete with a latch and strike plate, making it a ready-to-install solution for residential interior door applications. Installed by carpenters, finish contractors, or experienced DIYers.

This passage set is suited for residential interior doors where a non-latching, free-passage function is needed. The Octagon knob profile paired with the Modern Rectangle rosette provides a clean, geometric aesthetic that fits contemporary and transitional interior design schemes. The Flat Black finish coordinates with modern hardware and fixture finishes common in current residential construction and remodel projects. Typical applications include hallway doors, pantry doors, closet doors, and other interior openings that do not require locking or privacy functions.

Installation Notes

Installation is typically performed by a finish carpenter or experienced installer using a door bore kit, chisel, and screwdriver. Confirm door thickness and bore diameter before installation to ensure proper fit. Verify backset requirement - 2-3/8 inch or 2-3/4 inch - before ordering, as the latch must match the existing door prep. No power should be a concern for this product, but ensure the door is stable and properly hung before installing hardware.
