Emtek 8121EUS19 Egg Knob Passage Set Flat Black

Product Description

The EMTEK 8121EUS19 is a passage knob set designed for interior doors where latch function is required but locking is not. Built around the Egg Knob profile and mounted on a rectangular rose, this set installs on doors ranging from 1-1/4 inches to 2 inches thick and uses a standard 2-3/8 inch backset. The flat black finish delivers a clean, consistent look suited to modern and transitional interiors. Carpenters, finish contractors, and skilled DIYers handle installation using basic hand tools and a standard door prep kit.

This passage set is intended for interior applications such as hallways, closets, and common-area doors where a turn or push function is all that is needed. The rectangular rose provides a defined, geometric frame around the knob that pairs well with contemporary trim profiles. Door thickness compatibility from 1-1/4 inches to 2 inches covers the range of standard residential hollow-core and solid-core interior doors. The 2-3/8 inch backset is the most common backset dimension found in pre-bored residential door slabs.

Installation Notes

Installation should be performed by a finish carpenter or experienced installer using a standard door hardware installation kit. Confirm door bore diameter, backset measurement, and door thickness before ordering, as passage sets are not adjustable after assembly. Follow the manufacturer included template and instructions for proper rose and latch alignment. Do not force the knob spindle during assembly, as overtightening can affect smooth latch operation.
