Emtek Modern Designer Brass Knobset - Octagon Knob, Dummy (Pair)

Yes, wrong choice. The Octagon dummy is non-keyed and has no latch or lock mechanism at all. For a door that needs to stay shut, go passage; for a bath or bedroom, privacy. Residential-style options in the same vein include the Baldwin Estate 5011 Colonial passage knob and the Deltana 6112 St. Thomas privacy knob. For commercial traffic look at a graded cylindrical lock such as the Corbin Russwin CK4410 Grade 2 passage.

The Emtek Octagon knobset is a dummy function knob sold as a pair, meaning trim on both faces of the door. If you only need dummy trim on one side, the Schlage A170 is a single dummy trim, Grade 2 cylindrical non-keyed knob lock in the A Series, and the BEST 6K Series 6K-1DT is a single dummy trim, Grade 2 non-keyed cylindrical knob. Both cover one face rather than two, so a pair of doors or a double door would need two of them.

The Emtek Octagon dummy knobset has no locking mechanism, so it is not suited to a bath or bedroom. For privacy function knobs, the Dexter C2000 Series privacy ball knob is Grade 2 and non-keyed for 1-3/8 inch to 1-3/4 inch doors, the Pamex FTF Baron privacy knob and the Cal-Royal BER20 with brass trim are both Grade 3 for the same door thickness range, and on the decorative side the Baldwin Estate 5077 Bethpage privacy knob with R027 rose and the Deltana 6112 St. Thomas privacy knob are available.

The Emtek Octagon dummy set is non-keyed dummy trim with no latch, so the door will not stay shut on its own. For a latching but non-locking hall or closet door, the Dexter C2000 Series passage ball knob is a Grade 2, non-keyed passage lock for 1-3/8 inch to 1-3/4 inch doors, the Corbin Russwin CK4410 is a Grade 2 passage/closet cylindrical lock with a Global knob, and the Pamex FTF Baron is a Grade 3 knob lockset in passage function. On the decorative side, the Omnia 434/PA is a passage latchset with an egg-shaped knob in solid brass.

The Emtek Octagon dummy knobset is rated for doors 1-3/8 inch to 1-3/4 inch thick. For a 2 inch door, the Corbin Russwin CK4310 Grade 1 passage/closet cylindrical lock and the CK4851 entrance/office lock both cover 1-3/8 inch to 2 inch, as do the Deltana 3381 Egg Knob entry and 6171 Round Knob entry. The Falcon X101 Grade 1 heavy duty passage knobset goes to 2-1/4 inch. Those are latching functions rather than dummy trim.

The Emtek Octagon dummy pair is surface mount and requires no door prep, so it is the choice for a door with no bore. If the door already has a standard cylindrical bore, a dummy trim built on that prep fits better: the Schlage A170 is a Grade 2 cylindrical single dummy trim in the A Series and the BEST 6K-1DT is a Grade 2 cylindrical single dummy trim. Either will cover the existing hole where surface-mounted trim would not.

The Emtek Octagon is a residential dummy knob and no fire rating is carried for it. For fire-rated openings, the Falcon W101 is a Grade 2 medium duty cylindrical knob lock in passage/closet function with a 2-3/4 inch backset and a fire rating, and the Falcon X101 is a Grade 1 heavy duty passage knobset with interchangeable core, also fire rated, for doors 1-3/8 inch to 2-1/4 inch.

Six rosette shapes are offered: Disk, Modern Rectangular, Modern, Neos, Square and Urban Modern. Any brass rosette can be paired with the Octagon knob, so you can match the rose profile already used on the other doors in the house and keep the knob consistent.

Seven finishes: Flat Black (US19), Oil Rubbed Bronze (US10B), Polished Chrome (US26), Polished Nickel Lifetime (US14), Satin Brass (US4), Satin Nickel (US15) and Unlacquered Brass (US3NL). There is an optional split finish field on the order, so you can specify a different finish on each face when the two rooms have different hardware schemes.

Brass is the material and substrate, in Emtek's Brass collection. It is classified residential, so for apartment common areas, offices, schools or anywhere with heavy cycle counts you want a graded cylindrical lock instead, for example the Schlage D10S Grade 1 passage or the Falcon X101 Grade 1 heavy duty passage knobset.

Both are dummy knobs with no latch or locking mechanism. The Cal-Royal BA40 is a dummy knob cylindrical lock in the Barrington BA Series rated for 1-3/8 inch to 1-3/4 inch doors, the same door thickness range the Emtek Octagon dummy covers. The difference is in the trim and configuration: the Emtek Octagon is a brass knob sold as a complete pair and can be ordered with any brass rosette, in finishes including Flat Black US19, Oil Rubbed Bronze US10B, Polished Chrome US26, Satin Brass US4, Satin Nickel US15, Polished Nickel US14 and Unlacquered Brass US3NL.

The Emtek Octagon is a non-keyed dummy knob pair with no latch and no cylinder, used as a pull on closet or French doors. The Kwikset 400P Polo is a keyed entry knob lock supplied with a 6AL latch and RCS strike, and the 400P-CP clear pack version is Grade 3 for 1-3/8 inch to 1-3/4 inch doors. If the opening needs to lock with a key, the dummy set will not serve it.

The Emtek Octagon is a dummy-only brass knobset in the Octagon series, offered in Flat Black US19, Oil Rubbed Bronze US10B, Polished Chrome US26, Polished Nickel US14, Satin Brass US4, Satin Nickel US15 and Unlacquered Brass US3NL, with Disk, Modern, Modern Rectangular, Neos, Square and Urban Modern rosette choices. If you want one knob design carried across dummy, passage and privacy in a single line, Dexter's C2000 Series covers passage, privacy, entry/office and classroom on the same ball knob, and Pamex's FTF Baron covers entrance/office, privacy and passage at Grade 3.

No. The Sargent 78-2875 is an outside knob only with B design in the 7800 Series and the Imperial USA ED-BKL580 is knob trim in storeroom function from the ED-500 Series; both are trim for exit device hardware rather than standalone door knobs. The Emtek Octagon dummy pair is surface-mounted brass knob trim for a door with no lock mechanism at all. For dummy trim on a conventional door, the Schlage A170 single dummy trim or the Bravura Biloxi dummy knobset are the right direction.

If the old trim sat on a bored door, the Octagon dummy will cover the hole area only as far as the rosette diameter allows, since this set mounts to the door surface rather than through a cross bore. Swapping from a bored dummy such as the Cal-Royal BA40 or Bravura Biloxi is a rosette-coverage question, not a backset one. Where the existing hole must be filled by the trim, a bored dummy is the cleaner replacement.
