Emtek 8100EUS19 Egg Knob Passage Set Flat Black

Product Description

The EMTEK 8100EUS19 is a passage knob set featuring the Egg knob design paired with a regular rose, finished in Flat Black. Passage sets have no locking function, making them suited for interior doors such as hallways, closets, and common areas where privacy lock is not required. The set is configured for a 2-3/8 inch backset and fits doors ranging from 1-1/4 inches to 2 inches in thickness. Installation is handled by finish carpenters, general contractors, or experienced DIYers working on residential interior door hardware.

This passage set is appropriate for residential interior applications where a non-locking knob is specified. It works on standard interior door preparations and is commonly installed during new construction, remodels, or hardware upgrade projects. The Flat Black finish suits transitional, modern, and industrial design schemes. The regular rose provides a clean, low-profile mounting at the door face. The 2-3/8 inch backset is the most common backset dimension found in residential pre-hung interior doors.
