Emtek 5112OCTUS4 Octagon Passage Knob Satin Brass

Product Description

The EMTEK 5112OCTUS4 is a passage knob set featuring an octagon-profile knob paired with a modern rectangular rose, finished in satin brass. Passage function means the latch operates freely from both sides with no locking mechanism, making it suited for interior hallway and common-area doors. The set is configured for a 2-3/8 inch backset and fits doors ranging from 1-3/8 inches to 2 inches thick. Hardware is assembled to order at the manufacturer's facility in Southern California. Installers and finish carpenters working on residential interior door projects will find the octagon knob profile compatible with both transitional and contemporary design schemes.

This passage set is intended for interior doors where security is not required — hallways, closets, and living spaces are the most common applications. The modern rectangular rose provides a clean, low-profile base that suits doors with flat or lightly detailed casing. The satin brass finish coordinates with warm-toned metal fixtures throughout a room. Door thickness compatibility of 1-3/8 inches to 2 inches covers standard interior hollow-core and solid-core residential slabs. The 2-3/8 inch backset is the industry-standard measurement for most pre-bored interior door slabs.

Installation Notes

Installation is typically performed by a finish carpenter, locksmith, or experienced DIYer using a screwdriver and drill.

No latch reinforcement or deadbolt prep is required for passage function. Follow the manufacturer's included template and instructions to ensure proper rose alignment and latch engagement.
