Sargent 8XU93 LB 10BE – Frequently Asked Questions

1) What does the Sargent 8XU93 dummy knob actually do, and does it latch?
The 8XU93 is dummy trim only. There is no latch and no cylinder, so the knob is fixed and the door is held shut by something else, typically a roller catch, ball catch, or a flush bolt on the inactive leaf of a pair. Use it where you want matching knob trim on a door that does not need to operate. If you need the knob to retract a latch, you want a passage function instead.
2) Will the Sargent 8XU93 dummy knob fit a 1-3/4 inch commercial door?
Yes. The 8X Line dummy trim covers doors from 1-3/8 to 1-3/4 inches, which takes in both standard commercial 1-3/4 inch doors and older 1-3/8 inch interior leaves. Backset prep on the 8X Line runs 2-3/8 to 2-3/4 inches, with 2-3/4 inches standard, though a dummy trim mounts to the door face rather than latching into the frame.
3) Can I use a dummy knob on a fire-rated door?
The Sargent 8X Line is UL-cUL listed with a fire rating up to 3 hours, so the trim is suitable for fire-rated door assemblies. Bear in mind a dummy has no latching hardware of its own, so on a fire door the latching or bolting required by the assembly has to come from other hardware on that leaf.
4) I need the door to actually latch, not just carry trim - what should I order instead of the Sargent 8XU93?
The Sargent 8XU93 is dummy trim, so it has no latch and no keyed function. For a latching non-keyed knob in the same Grade 1 class, the Schlage D10S passage latch is a Grade 1 heavy duty cylindrical knob with passage function, and the Corbin Russwin CK4310 is a Grade 1 passage/closet cylindrical knob covering doors 1-3/8 inch to 2 inch. The Falcon X101 is another Grade 1 heavy duty cylindrical passage knobset, listed for 1-3/8 inch to 2-1/4 inch doors and fire rated.
5) What is the closest equivalent to the Sargent 8XU93 dummy knob from another commercial lock brand?
The Schlage A170 single dummy trim is the nearest cross-brand match in function: it is a cylindrical non-keyed knob dummy trim, like the Sargent 8XU93. The difference is the certification level - the Sargent 8XU93 is ANSI/BHMA Grade 1, while the Schlage A170 is Grade 2, and the A170 lists a door thickness range of 1-3/8 inch to 1-7/8 inch. Both are described as heavy duty.
6) Is there a lighter-duty dummy knob trim if Grade 1 is more than the door needs?
Yes. The BEST 6K Series single dummy trim is a Grade 2, medium duty non-keyed cylindrical knob with the same dummy function as the Sargent 8XU93. Choose it where the opening is a low-traffic interior door; the Sargent 8XU93 is Grade 1 heavy duty and holds a UL-cUL fire rating up to 3 hours for fire-rated assemblies.
7) Do I need to order the Sargent 8XU93 left hand or right hand?
No handing to specify. The 8XU93 is non-handed, so one part works on either leaf and either swing. That also makes it simple to stock as a spare across a building.
8) Is a Grade 1 dummy knob worth it over a Grade 2 dummy?
The 8XU93 carries ANSI/BHMA Grade 1 and is rated heavy duty, which matters on high traffic openings and where a facility standardizes everything on Grade 1. If the door is low traffic and you only want the knob to look right, a Grade 2 dummy such as the BEST 6K Series single dummy trim or the Schlage A170 single dummy covers it. Note the Schlage A170 lists a wider door range, 1-3/8 to 1-7/8 inches.
9) Can the Sargent 8XU93 be keyed into our master key system later?
No. The 8XU93 is non-keyed dummy trim with no cylinder, so it cannot be brought into a keying system. Other functions in the Sargent 8X Line accept SARGENT standard, Signature and Degree cylinders, so a keyed 8X function on the same door will match the master key system and the knob styling.
10) Will the 8XU93 match the other Sargent knob trim already on our doors?
It is 8X Line Series knob trim, so it carries the same knob and rose styling as the rest of the Sargent 8X Line cylindrical locks. Order it in the finish that matches what is on the other openings, 03, 10BE or 32D, and the dummy leaf will read the same as the working leaves beside it.
11) Is the 8XU93 a single dummy or a pair of knobs?
The 8XU93 is single dummy trim, one knob for one face of the door. For a pair of French doors or a closet needing a knob on both sides, order two, or look at a matched pair product such as the Emtek Arts and Crafts Hammered Egg dummy pair. Those Emtek sets are decorative rather than commercial Grade 1 hardware.
12) Can a passage knob be used in place of the Sargent 8XU93 dummy trim?
They are not interchangeable. The Sargent 8XU93 is dummy function - fixed trim with no latch. Passage knobs such as the Arrow MK01 and RK01 (both Grade 2, passage/hall/closet, 1-3/8 inch to 1-3/4 inch doors), the Dexter C2000 passage ball knob (Grade 2), and the Pamex FTF passage knob (Grade 3) all operate a latch bolt and require a latch and strike prep in the door. Use one of those where the door must latch shut, and the 8XU93 where the leaf is inactive or pull-only.
13) What keyed knob lock pairs with the Sargent 8XU93 on the active leaf of a pair of doors?
The Sargent 8XU93 is non-keyed dummy trim for the inactive leaf. For a keyed Grade 1 knob on the active leaf, the BEST 8K Series entrance function single cylinder knob is Grade 1 heavy duty, and the Corbin Russwin CK4851 entrance/office cylindrical knob is listed Grade 1 for doors 1-3/8 inch to 2 inch. Note the 8XU93 itself accepts SARGENT standard, Signature and Degree cylinders only where a keyed 8X Line function is used.
14) Is the Sargent 8XU93 dummy knob suitable for exterior doors?
Yes, the 8X Line dummy trim is specified for interior and exterior use. On an exterior opening it is typically the pull-side trim on an inactive leaf or on a door secured by an exit device or separate deadbolt, since the dummy itself provides no security.
15) Is there a Grade 2 dummy knob with a decorative rose instead of the Sargent 8XU93?
The Bravura Biloxi dummy knobset with round trim is a Grade 2 dummy knob option, and the Cal-Royal BA40 Barrington series dummy knob is a cylindrical dummy fitting doors 1-3/8 inch to 1-3/4 inch. The Sargent 8XU93 is the Grade 1 heavy duty commercial choice in the same non-keyed dummy role, non-handed for either door swing.
