Baldwin Reserve Traditional Non-Turning One-Sided Dummy Knob with Traditional Rose

It's trim only. The Reserve Traditional dummy knob is a non-turning, non-keyed knob with no latch and no lock behind it, so the knob is fixed and the door has to be held shut some other way (ball catch, roller catch, magnetic catch). It's what you put on a closet or hallway door that doesn't need to lock but should match the working knobs elsewhere in the house.

Yes. The Reserve dummy mounts in the same 2-1/8 inch standard bore used for a passage, privacy or entry knob, with a 1 inch edge bore. Swap a working knob out for the dummy and nothing new gets drilled. It also means a door that's already prepped from a previous lock takes this without patching.

It's a residential product. For multifamily corridors, offices, schools or anywhere the opening sees commercial traffic or has to meet a graded spec, go to a Grade 1 or Grade 2 cylindrical instead. The Schlage A170 single dummy trim is the direct Grade 2 dummy equivalent, and BEST's 6K Series single dummy trim is another Grade 2 dummy. For working (non-dummy) openings on the same job, the Corbin Russwin CK4310 is a Grade 1 passage knob covering 1-3/8 to 2 inch doors.

Wrong part. A dummy knob doesn't turn and has no latch or lock, so it can't secure a bedroom or bath. You want a privacy function: the Dexter C2000 Series privacy ball knob is Grade 2 for 1-3/8 to 1-3/4 inch doors, the Deltana 6112 St. Thomas privacy knob covers 1-3/8 to 2 inch, and Cal-Royal's BER20 is a Grade 3 privacy knob. Use the dummy only on closet, pantry or inactive doors where a catch holds the door shut.

A one-sided dummy such as the Baldwin Reserve Traditional dummy knob covers one face only, so a pair of doors or a knob wanted on both faces takes two. Where a matched pair in one part number is preferred, Emtek sells dummy knobsets as pairs: the Arts and Crafts Hammered Egg dummy pair and the Classic Brass Crystal Georgetown and Providence dummy pairs each ship two knobs per set. Emtek Porcelain knobs also come two knobs per set with threaded rod.

The Schlage A170 single dummy trim is the nearest like-for-like: it is a non-keyed cylindrical dummy knob in the A Series, rated Grade 2 and heavy duty, covering doors 1-3/8 inch to 1-7/8 inch. The Baldwin Reserve Traditional knob is likewise a non-keyed cylindrical dummy with no latch, so both mount a fixed knob on a door leaf that does not move. The A170 is a commercial-styled trim; the Baldwin carries a Traditional design in a Reserve residential collection with arch, round, or square rose choices.

A dummy knob does not turn and has no latch, so a door that must stay closed needs a passage function instead. In knob trim, the Dexter C2000 passage ball knob is Grade 2 for doors 1-3/8 inch to 1-3/4 inch, the Corbin Russwin CK4310 passage/closet lock is Grade 1 with a Global knob for doors 1-3/8 inch to 2 inch, and the Schlage D10S passage latch is a Grade 1 heavy duty Orbit knob in the D Series. In a traditional residential look, the Omnia 434/PA egg-shaped knob latchset is a passage function in solid brass.

No - it is a non-keyed dummy with no locking mechanism. A door needing a thumbturn lock takes a privacy function: the Dexter C2000 privacy ball knob is Grade 2 for 1-3/8 inch to 1-3/4 inch doors, the Pamex FTF Baron knob lockset in privacy function is Grade 3 for the same thickness range, and the Deltana 6112 St. Thomas knob is a privacy function for 1-3/8 inch to 2 inch doors.

Several knob trims are exit device or lock trim rather than a standalone dummy. The Sargent 78-2875 is an outside knob only with B design in the 7800 Series, the Sargent 28C-KNOB is exit device trim with knob and rose in entrance function for 1-3/4 inch doors, and the Imperial USA ED-BKL580 is knob trim in storeroom function for the ED-500 Series. Those mount to a device or lock body; the Baldwin Reserve Traditional dummy knob mounts to the door itself within the 2.125 inch standard door prep and does not turn.

Three rose shapes: Traditional Arch (TAR), Traditional Round (TRR), and Traditional Square (TSR). Pick the one that matches the roses already on your other Reserve openings, since the rose is what reads at a distance far more than the knob does. All three shapes are offered across the same eight finishes.

Eight finishes: 003 Polished Brass PVD, 044 Satin Brass PVD, 055 Polished Nickel PVD, 112 Venetian Bronze, 150 Satin Nickel, 152 Matte Antique Nickel, 190 Satin Black and 260 Polished Chrome. The three PVD finishes are the ones to specify where you want the brass or nickel to hold its color under heavy handling. Each finish is available with any of the three rose shapes.

Yes, both are handled as written-in options when you order: split rose lets you pair a knob with a rose other than the standard pairing, and split finish lets the two elements carry different finishes. That's how you keep a hallway side matching the corridor scheme while the closet interior matches something else. Neither is required; leave them blank for the standard matched combination.

A passage knob turns and retracts a latch, so the latch keeps the door closed and you operate it to open. A dummy knob does neither, so the door needs a separate catch to stay shut, and it's usually chosen on an inactive leaf or where the door already has a magnetic or ball catch. If you want the latch, the passage versions include the Dexter C2000 passage ball knob (Grade 2, 1-3/8 to 1-3/4 inch) and the Arrow MK01 (Grade 2, 1-3/8 to 1-3/4 inch).

The Bravura Biloxi dummy knobset with round trim is a Grade 2 dummy in the Biloxi series, the BEST 6K Series single dummy trim is a Grade 2 medium duty non-keyed cylindrical dummy knob, and the Cal-Royal BA40 in the Barrington BA series is a dummy cylindrical knob for doors 1-3/8 inch to 1-3/4 inch. Each performs the same fixed-knob role as the Baldwin Reserve Traditional dummy without the multi-rose and multi-finish selection.

The Baldwin Reserve Traditional dummy knob is a residential product. Where a graded commercial knob is required, the BEST 8K Series entrance single cylinder knob lock is Grade 1 heavy duty, the Sargent 8XG04 storeroom/closet single cylinder knob lock is Grade 1 heavy duty with a 2-3/4 inch backset, and the Falcon W101 Grade 2 cylindrical knob is a passage/closet latch function with a 2-3/4 inch backset and a fire rating.

Baldwin's dummy knob is built to match the look of an active passage, privacy, or entry door within the same 2.125 inch door prep, so the pairing is normally done within the Reserve Traditional design. Across other brands, dummy and passage functions come from the same series in several lines: Omnia offers the 434/0 egg-shaped single dummy alongside the 434/PA egg-shaped passage latchset, and Dexter offers the C2000 passage ball knob at Grade 2 for 1-3/8 inch to 1-3/4 inch doors next to the C2000 privacy and entry/office knobs.
