Product Information
Description
The UFD 7204 Series is a commercial knob lockset for fire-rated doors, built from 304 stainless steel with a satin nickel finish and UL listed for 3-hour fire door assemblies. It delivers code-compliant fire door hardware at a price point that works for apartment buildings, contractors outfitting multiple units, property managers, and light commercial projects where a traditional round knob is preferred over a lever.
The 75mm (2-15/16") rose fits standard cylindrical door preps. Each knob lockset includes a 70mm (2-3/4") backset latch, 1-1/8" faceplate, and a 4-7/8" ASA strike plate. Keyed functions include two SC1 (Schlage C) keys.

Knob vs. Lever
Knob locksets are common on existing residential and multifamily doors and are often the right match for replacement work. Note that ADA-compliant openings in public and commercial buildings generally require lever handles; for those doors see the 7201 Series fire-rated lever lockset, which shares the same stainless steel construction and 3-hour UL rating.
