Sargent 28-6U65 OB 26D – Frequently Asked Questions

1) Will the Sargent 6U65 privacy knob lock fit a 1-3/8 inch door, or does it need a 1-3/4 inch door?
Both work. The 6U65 privacy knob lock covers door thickness from 1-3/8 to 1-3/4 inches, so it drops onto older interior wood doors as well as standard commercial 1-3/4 inch doors with no extra kit.
2) Which backset do I order for the Sargent 6U65 knob lock?
You pick it at order time: 2-3/8 inch or 2-3/4 inch. Measure from the door edge to the center of the existing bore. Residential and lighter commercial prep is usually 2-3/8; commercial hollow metal frames are commonly 2-3/4. Ordering the wrong one means the knob will not line up with the existing cross-bore.
3) Is the Sargent 6U65 keyed, and how does it unlock in an emergency?
It is a non-keyed privacy function, the bed and bath type: you lock it from inside the room, and there is no cylinder or key. There is no keyway to key into a building master system, so if you need staff key access to that door you want an entrance/office or classroom function instead.
4) What is the closest Grade 2 privacy knob lock to the Sargent 6U65 from another manufacturer?
The Dexter C2000 Series privacy knob lock is the nearest match: it is a Grade 2 cylindrical ball knob privacy/bed/bath lock, non-keyed, with a 1-3/8 inch to 1-3/4 inch door thickness range, which is the same door thickness range the Sargent 6U65 covers. The 6U65 is also Grade 2, non-keyed, privacy/bedroom/bath function with a knob handle.
5) I need a knob lock for a closet or hallway door, not a bathroom. What should I order instead of the Sargent 6U65?
The 6U65 is privacy/bedroom/bath function, which has an inside locking button and is not what you want on a closet or corridor door. For a non-locking passage knob in Grade 2, the Corbin Russwin CK4410 is a Grade 2 passage/closet cylindrical lock with a Global knob and a 1-3/8 inch to 1-3/4 inch door range, and the Falcon W101 is a Grade 2 medium duty passage/closet knob lock with a 2-3/4 inch backset and a fire rating.
6) The opening needs to be keyed. What knob lock replaces the Sargent 6U65 in that case?
The 6U65 is non-keyed, so it cannot take a key cylinder. For a keyed knob on a similar cylindrical prep, the Dexter C2000 entry/office knob lock is Grade 2 and keyed for 1-3/8 inch to 1-3/4 inch doors, the Dexter C2000 classroom knob lock is Grade 2 and keyed over the same range, and the Corbin Russwin CK4851 is an entrance/office cylindrical knob lock with a conventional cylinder for 1-3/8 inch to 2 inch doors.
7) My spec calls for Grade 1 knob locks. Is the Sargent 6U65 acceptable, and what are the Grade 1 knob options?
The Sargent 6U65 is ANSI/BHMA Grade 2, so it will not meet a Grade 1 requirement. Grade 1 cylindrical knob locks include the Corbin Russwin CK4310 passage/closet knob for 1-3/8 inch to 2 inch doors, the Falcon X101 heavy duty passage knobset with interchangeable core for 1-3/8 inch to 2-1/4 inch doors, the Schlage D10S heavy duty passage latch with Orbit knob, and the BEST 8K entrance function single cylinder heavy duty knob lock.
8) The door is thicker than 1-3/4 inches. What privacy or knob lock works where the Sargent 6U65 does not?
The 6U65 accommodates door thickness from 1-3/8 inch to 1-3/4 inch. For thicker doors, the Deltana 6112 St. Thomas privacy knob covers 1-3/8 inch to 2 inch, the Corbin Russwin CK4310 passage knob covers 1-3/8 inch to 2 inch, and the Falcon X101 passage knobset covers 1-3/8 inch to 2-1/4 inch.
9) Do I need to worry about handing when ordering the Sargent 6U65?
No. The 6U65 is non-handed, so one part number covers left and right hand openings. That makes it easy to stock a few on the shelf for a mixed building without tracking swing.
10) Is a Grade 2 standard duty knob lock enough for a commercial restroom?
For a standard duty commercial restroom or office bedroom door, yes. The 6U65 carries ANSI/BHMA A156.2 Series 4000 Grade 2 certification and is built for commercial use. For high traffic public restrooms or school corridors where you want Grade 1, look at a heavy duty Grade 1 cylindrical such as the Schlage D Series or the Falcon X Series instead, though those are passage function, not privacy.
11) What else could I use if the Sargent 6U65 privacy knob isn't the right fit?
Other privacy knob locks we carry cover different needs. The Dexter C2000 privacy ball knob is also Grade 2 and fits 1-3/8 to 1-3/4 inch doors. The Cal-Royal BER20 and the Pamex FTF privacy knob are Grade 3 for lighter duty on the same thickness range. For residential and decorative work, the Deltana 6112 St. Thomas privacy knob handles 1-3/8 to 2 inch doors, and the Baldwin Estate 5000 Baltimore privacy knob comes preconfigured with a 2-3/8 inch backset and full lip strike.
12) Do the Sargent 6 Line knobs match across a building if I'm replacing hardware a few doors at a time?
The 6 Line privacy knob comes in three finishes, 03 bright brass clear coated, 10BE dark oxidized satin bronze, and 26D satin chromium plated over nickel. 26D is the usual commercial standard. Since the 6 Line family runs other functions on the same bored prep, you can keep one look across privacy, passage and keyed openings as you work through a property.
13) Is there a lighter-duty privacy knob lock instead of the Sargent 6U65?
Yes. The Cal-Royal BER20 is a Grade 3 privacy knob lock with brass trim covering 1-3/8 inch to 1-3/4 inch doors, and the Pamex FTF Baron is a Grade 3 privacy knob lockset over the same door thickness range. The Sargent 6U65 is the Grade 2 standard duty commercial option in privacy function.
14) Is a dummy knob a substitute for the Sargent 6U65 privacy knob?
No. A dummy trim has no latch and no locking function at all - it is surface-mounted pull trim. The BEST 6K single dummy trim, the Schlage A170 single dummy trim, and the Cal-Royal BA40 dummy knob are all dummy function and will not latch or secure a bathroom door. The Sargent 6U65 is a privacy/bedroom/bath lock with a 1/2 inch latchbolt throw.
15) For a residential-style privacy knob with decorative trim, what compares to the Sargent 6U65?
The Baldwin Estate 5000 Baltimore knob privacy lock comes preconfigured with a 5148 rose, a 2-3/8 inch backset and a full lip strike, and the Baldwin Estate 5077 Bethpage privacy knob uses an R027 rose. The Sargent 6U65 is the commercial-duty counterpart, Grade 2 with a 2-3/8 inch standard backset and full lip and ANSI strike choices.
16) Is there an antimicrobial version of the Sargent 6 Line knob for a healthcare corridor?
Yes. The 6 Line knob lock can be supplied with the MicroShield antimicrobial coating, which is what you want on patient rooms, food service areas and other infection control spaces. It is an option to specify, not the default build.
17) How hard is the Sargent 6U65 to install or swap out?
It is a standard bored cylindrical install: prep or verify the existing cross-bore at the backset you ordered, run the latch in the edge bore, and the lockbody secures with just two screws. Sargent publishes installation instructions and a 6 Line parts list, so servicing a knob or latch later does not mean pulling the whole lock off the building.
