Emtek 5110ROUUS19 Round Knob Passage Set Flat Black

Product Description

The EMTEK 5110ROUUS19 is a round knob passage set finished in Flat Black, designed for interior doors where a latch mechanism is required but locking function is not. It ships with a square rose trim plate and is configured for a 2-3/8 inch backset, fitting doors ranging from 1-1/4 inches to 2 inches in thickness. Passage sets in this configuration are standard installs for hallways, closets, and interior rooms where traffic flow control is the primary function. The hardware is custom assembled and sold as a single unit.

This passage set is suited for residential interior door applications including hallways, pantries, and bedroom or closet doors where no lockset function is needed. The square rose provides a clean, geometric trim profile that pairs with contemporary and transitional interior design themes. The Flat Black finish coordinates with modern fixture and hardware palettes.

Installation Notes

Installation is typically performed by a finish carpenter, general contractor, or experienced DIYer using a drill, hole saw, and chisel for mortising the latch plate. Ensure the door bore and latch prep match the 2-3/8 inch backset before installation. Remove the door from the frame if needed for cleaner latch mortise work. Follow the manufacturer instruction sheet included with the hardware for proper spindle and rose alignment.
