Deltana 3384D Egg Knob Dummy

No latch, no moving parts. The Deltana 3384D Egg Knob is a dummy, meaning the knob is fixed in place and used as a pull or a push point. It doesn't turn, doesn't retract a latch, and doesn't lock. Typical spots are closet doors held shut by a ball catch or roller catch, one leaf of a French pair, or a pantry door. If the door actually needs to latch when it closes, you want a passage function instead, like the Bravura Albany or Lynchburg passage knobset.

Neither one. The 3384D is universal handed, so the same knob works on a left- or right-hand door. And because it is a dummy, there's no latch running into the edge of the door, so backset doesn't enter into it. Mounting is to the face of the door, not into a bored edge prep. That makes it a straightforward pick for a door that was never prepped for a working lock.

If what's coming off is a face-mounted dummy knob, a dummy replaces a dummy without touching the door prep, and the 3384D egg shape will read as a match against other egg knobs in the house. The thing to check first is whether the old knob turned. If it rotated and pulled a latch back, it was a passage set and this won't work in its place. A dummy is fixed. For an egg-shaped set that does latch, the Omnia 434/PA is the egg-shaped passage latchset.

It won't. The Deltana 3384D egg dummy knob is a pull only, with no latch and no catch mechanism, so the door needs separate hardware to stay closed. A ball catch, roller catch, or magnetic catch at the head or the strike jamb does that job. Budget for it on the same order, because the knob alone leaves the door free to swing.

The Deltana 3384D is a residential dummy knob. For a commercial opening, the Schlage A170 single dummy trim is a Grade 2 cylindrical non-keyed knob in the A Series, rated heavy duty for doors 1-3/8 inch to 1-7/8 inch thick. The BEST 6K Series single dummy trim is a Grade 2 non-keyed cylindrical knob at a medium duty level. Both carry an ANSI/BHMA grade, which the residential 3384D does not trade on.

For an egg-shaped dummy knob, the Omnia 434/0 is the nearest match: it is a traditional egg-shaped knob single dummy interior lockset in solid brass. The Emtek Arts & Crafts Hammered Egg dummy is also an egg-profile dummy knob, supplied as a pair rather than a single. The Deltana 3384D is a non-keyed dummy knob in steel and zinc, offered in PVD Polished Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, and Antique Brass.

A dummy knob has no latch at all, so it will not hold a swinging door closed. The Omnia 434/PA is the same traditional egg-shaped knob in a latchset with a 3 inch projection, for an opening that needs to latch. For a passage latch in a plainer knob profile, the Pamex FTF passage lockset is Grade 3 for doors 1-3/8 inch to 1-3/4 inch, and the Dexter C2000 passage ball knob is Grade 2 over the same thickness range.

Trim-only knobs read like dummies in a photo but serve a different opening. The Sargent 78-2875 is an outside knob only with B design for the 7800 Series, the Sargent 28C-KNOB is exit device trim with knob and rose in an entrance function for 1-3/4 inch doors, and the Imperial USA ED-BKL580 is knob trim in a storeroom function for the ED-500 Series - all of those mount to an exit device or lock chassis, not to a blank door face. The Sure-Loc Arapaho and Sure-Loc Bergen round knob 6-pack are knobsets, and the Bergen has an adjustable backset, meaning a bored door and a latch. The Deltana 3384D is a non-keyed dummy for a door that does not latch.

The 3384D is sold as a dummy knob set in a single finish choice per order. For a pair of French doors where you want a knob on each leaf, order accordingly. If you specifically want a factory-boxed dummy pair, the Emtek Arts & Crafts Hammered Egg dummy is sold as a pair, and the Emtek Georgetown and Providence crystal knobsets ship as dummy pairs as well.

Steel and zinc is the construction on the 3384D egg knob, with the finish applied over it. That's a residential-grade build. If a solid brass body matters to you for a high-visibility opening, the Omnia 434/0 is an egg-shaped single dummy with solid brass construction, and the Omnia 442/00 and 458/0 are solid brass dummy knobsets as well.

The Deltana 3384D is non-keyed and has no cylinder, so it cannot be keyed. For a keyed knob, the Cal-Royal BER00 entrance/office knob lock is Grade 3 with a Kwikset keyway for doors 1-3/8 inch to 1-3/4 inch, the Kwikset 400P-CP keyed entry Polo knob is Grade 3 over the same thickness range with a round corner adjustable latch and round corner strike, and the Corbin Russwin CK4851 entrance/office cylindrical lock uses a conventional cylinder on a global knob for doors 1-3/8 inch to 2 inch.

The Cal-Royal BA40 from the Barrington BA series is a dummy knob cylindrical lock for doors 1-3/8 inch to 1-3/4 inch thick, in a plain knob profile rather than the egg shape of the Deltana 3384D. The Bravura Biloxi with round trim is a Grade 2 dummy knobset. Both give you the same non-latching dummy action on a false or fixed door.

A dummy knob does not lock, so a bath or bedroom needs a privacy function. The Pamex FTF Baron privacy knob lockset is Grade 3 for doors 1-3/8 inch to 1-3/4 inch, the Cal-Royal BER20 privacy knob lock is Grade 3 with brass trim over the same thickness range, and the Dexter C2000 privacy ball knob is Grade 2. In a decorative knob closer to the Deltana egg profile, the Baldwin Estate 5077 Bethpage privacy knob with R027 rose is a privacy function, and the Baldwin Estate 5000 Baltimore privacy knob with 5148 rose has a 2-3/8 inch backset and full lip strike.

The Deltana 3384D is a universal hand dummy knob, so it is not handed. Bored knob locks are the ones that pin you to a thickness range: the Arrow MK01 passage knob lock is Grade 2 for 1-3/8 inch to 1-3/4 inch, the Corbin Russwin CK4310 Grade 1 passage is 1-3/8 inch to 2 inch, the Falcon X101 Grade 1 passage knobset with interchangeable core runs 1-3/8 inch to 2-1/4 inch, and the Schlage A170 dummy trim covers 1-3/8 inch to 1-7/8 inch. If your door falls outside a chosen lock's range, the range is the deciding spec.

The Deltana 3384D is a dummy knob with no latch, so it is not a latching device on a rated opening. Among the knob locks, the Falcon W101 Grade 2 cylindrical passage/closet knob lock with 2-3/4 inch backset is fire rated at a medium duty level, and the Falcon X101 Grade 1 heavy duty passage knobset with interchangeable core is fire rated for doors 1-3/8 inch to 2-1/4 inch. Those are the ones to specify when the drawing calls for a rated assembly.

Deltana builds the knob line across several functions and designs, so the matching route is to stay within Deltana and pick the privacy or passage version of the same knob shape for the doors that need to function. That's how you keep one look across a unit. If you're mixing brands anyway, the Bravura Biloxi is a dummy on the same round-trim platform as their Albany and Lynchburg passage sets, which gives you a matched dummy-plus-passage family from a single maker.
