Sargent 6U93 OB 26D – Frequently Asked Questions

1) I need the knob on my closet doors to match the Sargent locks on the rest of the building. Will the 6U93 match?
That is exactly what a dummy is for. The 6 Line 6U93 uses the same knob and rose trim as the rest of the Sargent 6 Line bored locks, so a closet or inactive leaf reads identically to the keyed and passage openings beside it. Match the finish across the run: it comes in 03 bright brass with clear coat, 10BE dark oxidized satin bronze, and 26D satin chromium plated over nickel. 26D is the usual commercial specification.
2) Can I use a Sargent 6U93 dummy knob on a fire rated door?
A dummy knob is trim, not a latching device, so it does nothing to hold a fire door closed. A fire rated opening has to latch, which means the leaf carrying the 6U93 needs either a latching device of its own or, on a pair, flush bolts or a vertical rod device on the inactive leaf per the door assembly listing. The normal use is a closet or a non-rated opening. If the opening is rated and needs a knob that latches, step up to a latching 6 Line function or a Grade 1 device instead.
3) I ordered a Sargent 6U93 and got one knob. Do I need two for a door?
One knob per order. The 6U93 is a single dummy pull, so a door needing a knob on both faces takes two. Know that up front if you are covering an inactive leaf that gets used from both sides. Some decorative dummies are sold as pairs instead, such as the Emtek Arts and Crafts Hammered Egg and the Classic Brass Crystal Georgetown and Providence dummy sets, so count carefully when you are comparing.
4) What is the closest equivalent to the Sargent 6U93 single dummy knob from another commercial brand?
The Schlage A170 single dummy trim is the nearest match. Like the 6U93, it is a Grade 2 non-keyed cylindrical dummy knob, and it fits doors 1-3/8 inch to 1-7/8 inch thick, where the 6U93 covers 1-3/8 inch to 1-3/4 inch. The BEST 6K single dummy trim is also a Grade 2 dummy knob, rated medium duty. Both give you the same thing the 6U93 gives you: a fixed knob with no latch, mounted for pull only.
5) The door needs to actually latch, not just have a knob to pull. What should I order instead of the 6U93?
The 6U93 is a dummy function with no latch, so it will not hold a door closed. For a latching non-keyed knob in the same Grade 2 class, the Corbin Russwin CK4410 is a passage/closet cylindrical lock covering 1-3/8 inch to 1-3/4 inch doors, and the Dexter C2000 passage ball knob is Grade 2 over the same thickness range. If the opening runs heavy traffic, the Schlage D10S passage latch is Grade 1 heavy duty and the Falcon X101 passage knobset is Grade 1 heavy duty with an interchangeable core and a 1-3/8 inch to 2-1/4 inch thickness range.
6) What looks like a substitute for the Sargent 6U93 but is not?
Two traps. First, dummy knobs sold as pairs: the Emtek Arts and Crafts hammered egg dummy and the Emtek Georgetown crystal dummy are both dummy function but ship two knobs per set, while the 6U93 is a single knob pull for one face of the door. Second, passage knobs: the Arrow MK01 and Arrow RK01 are Grade 2 non-keyed like the 6U93, but they are passage/hall/closet function with a working latch, so they are not interchangeable with a fixed dummy. Check function and knob count before swapping.
7) The door is thicker than 1-3/4 inch. Which knob works where the Sargent 6U93 will not?
The 6U93 accommodates door thickness from 1-3/8 inch to 1-3/4 inch. For thicker doors, the Falcon X101 passage knobset covers 1-3/8 inch to 2-1/4 inch, the Corbin Russwin CK4310 and CK4851 both cover 1-3/8 inch to 2 inch, and the Lockey 3830 keyless combination knob covers 1 3/16 inch to 2 inch. Among decorative knobs, the Deltana 3381 egg knob entry and Deltana 6171 round knob entry are listed for 1-3/8 inch to 2 inch.
8) I need a fire-rated knob lock and the 6U93 dummy will not latch. What else carries a fire rating?
The Sargent 6U93 is UL-cUL listed for fire ratings up to 3 hours. Among latching knob locks, the Falcon W101 is a Grade 2 medium duty passage/closet latch with a fire rating and a 2-3/4 inch backset, and the Falcon X101 is a Grade 1 heavy duty passage knobset with a fire rating and an interchangeable core. Note the W101 backset is 2-3/4 inch against the 2-3/8 inch backset on the 6U93, so confirm the bore prep on the door before ordering.
9) Do I have to worry about handing or which way the door swings with the Sargent 6U93?
Handing is not a factor. The 6U93 is non-handed, and since it is a dummy knob with no latch and no strike, left hand, right hand, reverse bevel and swing direction all make no difference. One part number covers every opening. Order by finish only.
10) Is the Sargent 6U93 tough enough for a school or hospital corridor?
It is a Grade 2, standard duty commercial part, rated to ANSI/BHMA A156.2 Series 4000. That suits moderate traffic: offices, classrooms, patient rooms, multi-tenant residential. Being a dummy, it takes pull loads rather than turn cycles, so the wear pattern is gentler than on a working knob anyway. For a high abuse corridor or a main entry where people hang on the trim, a Grade 1 heavy duty chassis such as the Corbin Russwin CK4300 or the BEST 8K Series is the heavier class.
11) Do I need to bore the door or cut a 2-3/8 inch backset for a Sargent 6U93?
No latch bore and no edge prep. Dummy trim fastens to the door face, so there is no cross bore to drill through the edge for a latch and no strike to mortise into the frame. That is the practical difference from the passage and entrance functions in the 6 Line, which do need the full bored prep. On a door already bored for a working lock, the dummy rose will cover a standard 2-1/8 inch face bore.
12) Does the Sargent 6U93 take a key or a cylinder?
There is no cylinder and no keyway in the 6U93. It is non-keyed dummy trim, so nothing to key, nothing to add to a master key system, and no core to order. If you need a keyed knob in the same trim family, that is a different 6 Line function, and keying is specified on that order instead.
13) Can I put a Sargent 6U93 on a bathroom or bedroom door instead of a privacy knob?
No. The 6U93 is a non-keyed dummy, a fixed knob with no latch and no locking, so it cannot secure a bathroom or bedroom. For privacy function in the same Grade 2 class, the Dexter C2000 privacy ball knob covers 1-3/8 inch to 1-3/4 inch doors. Grade 3 privacy options include the Cal-Royal BER20 with brass trim and the Pamex FTF Baron privacy knob, both over the same 1-3/8 inch to 1-3/4 inch range. A 6U93 still has a place on that opening as the inactive-side pull on a closet or a fixed leaf.
14) The opening needs a Grade 1 knob instead of Grade 2. What replaces the Sargent 6U93?
The 6U93 is ANSI/BHMA A156.2 Series 4000 Grade 2, standard duty. For Grade 1 cylindrical knobs, the BEST 8K entrance function single cylinder knob lock is Grade 1 heavy duty, the Corbin Russwin CK4310 passage/closet knob is Grade 1 over 1-3/8 inch to 2 inch doors, and the Corbin Russwin CK4851 entrance/office knob with a conventional cylinder is Grade 1 over the same 1-3/8 inch to 2 inch range. Each of those is a working lock rather than a fixed pull, so specify the function the opening needs.
15) I am matching knobs across a building where some doors are keyed. What pairs with the Sargent 6U93 visually?
The 6U93 is a Grade 2 knob designed to blend with the trim designs of other Sargent locks, so keyed openings in the same series carry the look through. If you are standardizing on another brand instead, keep the family consistent: Dexter C2000 runs Grade 2 ball knobs in classroom, entry/office, passage and privacy across 1-3/8 inch to 1-3/4 inch doors, and Corbin Russwin runs the Global knob across the CK4410 Grade 2 passage and the CK4851 entrance/office. Pairing a dummy from one family with working locks from another leaves a visible mismatch on the same corridor.
16) Is a residential dummy or passage knob an acceptable swap for the Sargent 6U93 in a commercial building?
They are built to a different standard. The 6U93 is a commercial standard duty knob carrying ANSI/BHMA Grade 2 and a UL-cUL fire rating to 3 hours. The Kwikset 200P Polo passage knob and the Schlage Residential F500 Plymouth with Georgian knob, which covers 1-3/8 inch to 1-3/4 inch doors with adjustable backsets and dual strikes, are residential-line knobs, and the Kwikset 400P-CP keyed entry is Grade 3. If a drawing or a facility standard calls for Grade 2 on a fire-rated opening, those will not satisfy it.
17) Is there an antimicrobial version of the Sargent 6 Line knob for a healthcare job?
Sargent offers the 6 Line with MicroShield antimicrobial coating as an option, which is the usual pick for patient rooms, clinics, and food service areas where the touch surface matters. It has to be specified on the order, since it is a coating option rather than a separate catalog number you would find on its own.
