Emtek Lost Wax Cast Bronze Knobsets - Petal Knob, Dummy (Pair)

No door prep is needed. The Petal dummy knobset is surface mounted, so it screws to the face of the door with no 2-1/8 inch cross bore and no latch bore. That is what makes it the usual pick for a false door on a closet or an inactive leaf of a French pair, where there is nothing to latch.

It ships as a pair, one knob and rosette for each face of the door, sold as a complete set. If you only need a single knob on one side, a dummy pair is more than the job calls for, and something like the BEST 6K Series single dummy trim or the Omnia 434/0 single dummy is the single-side equivalent.

It won't. This is a dummy set: non-keyed, no latch, no turn. The knob is fixed and purely a pull. If the door has to stay closed or be usable as a real opening, you want a passage or privacy knob instead, for example the Dexter C2000 Grade 2 passage ball knob or the Pamex FTF Baron privacy knob.

It's a residential product and carries no ANSI/BHMA grade, so it won't satisfy a Grade 1 or Grade 2 line on a commercial spec. For graded cylindrical knob hardware, look at the Schlage A170 single dummy trim (Grade 2, heavy duty) or, for real lock functions, the Corbin Russwin CK4310 Grade 1 passage or Sargent 8XG04 Grade 1 storeroom.

The Emtek Petal lost wax cast bronze knob is a dummy function, non-keyed set. Dummy knob alternatives include the Schlage A170 single dummy trim, a Grade 2 cylindrical non-keyed knob for doors 1-3/8 inch to 1-7/8 inch thick; the BEST 6K Series single dummy trim, a Grade 2 medium duty non-keyed knob; the Cal-Royal BA40 dummy knob in the Barrington BA series for 1-3/8 inch to 1-3/4 inch doors; the Bravura Biloxi dummy knobset with round trim, Grade 2; and the Omnia 434/0 egg-shaped single dummy lockset in solid brass. Note that the Emtek is supplied as a pair, while the Schlage A170, BEST 6K-1DT, Omnia 434/0, Omnia 442/00 and Omnia 458/0 are single dummy trims.

The Emtek Petal lost wax cast bronze knob is a dummy: it surface mounts with no door prep and has no latch. If the door has to stay shut, order a passage set instead. Options include the Omnia 434/PA egg-shaped knob latchset in solid brass with a 3 inch projection; the Baldwin Estate 5011 Colonial passage knob with 5058 rose; the Baldwin Estate 5000 Baltimore passage knob with 5048 rose, 2-3/8 inch backset and full lip strike; the Pamex FTF Baron Grade 3 passage knob for 1-3/8 inch to 1-3/4 inch doors; and the Schlage D10S Grade 1 heavy duty Orbit knob passage latch.

The Emtek Petal lost wax cast bronze knob set is classified as residential and is a non-latching dummy. For openings where a specification calls out an ANSI/BHMA grade, choose a graded cylindrical knob lock instead: the Corbin Russwin CK4310 is Grade 1 passage/closet for doors 1-3/8 inch to 2 inch; the Falcon X101 is Grade 1 heavy duty passage with an interchangeable core, fire rated, for 1-3/8 inch to 2-1/4 inch doors; the Sargent 8XG04 is Grade 1 heavy duty storeroom with a 2-3/4 inch backset; and the BEST 8K Series is a Grade 1 heavy duty entrance knob lock.

The Emtek Petal lost wax cast bronze knob is non-keyed dummy trim, so it offers no privacy turn. For a bed or bath, the Deltana 6112 St. Thomas knob is a privacy set for 1-3/8 inch to 2 inch doors, the Pamex FTF Baron is Grade 3 privacy for 1-3/8 inch to 1-3/4 inch doors, the Cal-Royal BER20 is Grade 3 privacy with brass trim for the same thickness range, the Dexter C2000 privacy ball knob is Grade 2, and the Baldwin Estate 5077 Bethpage privacy knob uses an R027 rose.

Because it mounts to the surface, the rosettes are not sized to conceal a 2-1/8 inch bore. On a door already prepped for a bored lock, a dummy trim built for that prep, such as the Schlage A170 single dummy trim or the Bravura Biloxi dummy knobset, is the cleaner swap. Use the Petal dummy on an unprepped slab.

Handing does not apply. A dummy knob has no latch and no spindle rotation, so the same set works on a left or right hand door. What you do specify is finish (FB or MB) and rosette number, #11, #12, #14 or #15.

Watch for knob sets that share the bronze-era look but carry a different function. The Deltana 6112 St. Thomas knob is privacy and the Deltana 3381 Egg knob and 6171 Round knob are entry function, all for 1-3/8 inch to 2 inch doors, so they require latch and bore prep the Emtek Petal dummy does not. The Baldwin Estate 5077 Bethpage and 5000 Baltimore with 5148 rose are privacy sets with a turn. Exit device trims such as the Sargent 28C-KNOB, the Sargent 78-2875 outside knob only and the Imperial USA ED-BKL580 storeroom knob trim mount to a device, not to a bare door. The Emtek Petal set is surface mount with no door prep, and it is sold as a pair.

The Emtek Petal lost wax cast bronze set is non-keyed dummy trim, so a keyed opening needs a separate lock. Comparable keyed knob locks include the Deltana 6901 Portland knob entry for 1-3/8 inch to 1-3/4 inch doors, the Cal-Royal BER00 Grade 3 entrance/office knob with a Kwikset keyway, the Corbin Russwin CK4851 entrance/office cylindrical knob lock with a conventional cylinder for 1-3/8 inch to 2 inch doors, and the Kwikset 400P-CP Polo keyed entry knob, Grade 3, for 1-3/8 inch to 1-3/4 inch doors.

The Emtek Petal lost wax cast bronze dummy pair fits doors 1-3/8 inch to 1-3/4 inch thick. Peers listing the identical range include the Cal-Royal BA40 dummy knob, the Arrow MK01 and RK01 Grade 2 passage knob locks, the Corbin Russwin CK4410 Grade 2 passage/closet knob, the Dexter C2000 passage ball knob, and the Pamex FT3 Saturn Grade 3 knob lockset. The Schlage A170 dummy trim spans 1-3/8 inch to 1-7/8 inch, and the Corbin Russwin CK4310 spans 1-3/8 inch to 2 inch.

Lost wax cast bronze, part of Emtek's Tuscany Bronze collection. The cast bronze gives the surface texture and the darker Flat Black or Medium Bronze tones that a plated brass knob won't reproduce, which matters when you are matching an existing bronze suite on other doors.
