Emtek Modern Classic Brass Knobset - Orb Knob, Dummy (Pair)

Yes. The Orb knob can be paired with any of six brass rosettes: Disk, Modern, Modern Rectangular, Neos, Square, and Urban Modern. That is how you match a dummy leaf to passage or privacy openings elsewhere in the house that already use a given rose shape. A split finish option is also available if you want a different finish on each face.

It is classified as residential. For a commercial corridor, classroom, or any opening that has to meet a Grade 1 or Grade 2 requirement, look at cylindrical hardware instead, such as the Grade 1 Corbin Russwin CK4310 or the Grade 2 BEST 6K dummy trim. Traffic volume and grade requirements are the deciding factor, not the knob shape.

The Emtek Orb Orb knob is sold as a pair, so both faces of the door get a knob. If the opening only needs one side trimmed, single dummy knobs include the Schlage A170, a Grade 2 cylindrical non-keyed single dummy trim in the A Series for doors 1-3/8 to 1-7/8 inches thick, the BEST 6K-1DT single dummy trim, a Grade 2 medium duty non-keyed cylindrical knob, and the Omnia 458/0 single dummy knob latchset in solid brass. The Bravura Biloxi BV34722 is another Grade 2 dummy knobset with round trim.

A dummy knob has no latch mechanism, so it will not hold a door closed. For a hall or closet door that needs to latch but not lock, passage knobsets include the Corbin Russwin CK4310, a Grade 1 non-keyed passage/closet cylindrical lock for doors 1-3/8 to 2 inches thick, the Schlage D10S Grade 1 heavy duty passage knob lock with the Orbit knob, and the Dexter C2000 Grade 2 passage cylindrical ball knob for doors 1-3/8 to 1-3/4 inches. In solid brass with a traditional look, the Omnia 434/PA is an egg-shaped knob latchset with a 3 inch projection.

The Emtek Orb knobset is a residential brass knobset. For commercial openings that need an ANSI/BHMA grade, Grade 1 knob locks include the Falcon X101 heavy duty cylindrical passage knobset with interchangeable core, fire rated, for doors 1-3/8 to 2-1/4 inches, the Sargent 8XG04 Grade 1 heavy duty storeroom/closet knob lock with 2-3/4 inch backset, and the BEST 8K Series Grade 1 heavy duty entrance knob lock. At Grade 2, the Falcon W101 is a fire rated medium duty passage/closet knob lock with a 2-3/4 inch backset and the Sargent 6G04 is a storeroom/closet knob lock with single cylinder.

The Emtek Orb dummy pair is non-keyed with no locking function, so it will not work on a bed or bath door. Privacy knobsets include the Dexter C2000 Grade 2 privacy cylindrical ball knob for doors 1-3/8 to 1-3/4 inches, the Pamex FTF10 Grade 3 Baron privacy knob lockset for the same thickness range, the Cal-Royal BER20 Grade 3 privacy knob lock with brass trim, and the Deltana 6112 St. Thomas privacy knob for doors 1-3/8 to 2 inches. Baldwin's 5000 Baltimore privacy knob with 5148 rose comes preconfigured with a 2-3/8 inch backset and full lip strike.

Seven: Flat Black (US19), Oil Rubbed Bronze (US10B), Polished Chrome (US26), Polished Nickel Lifetime (US14), Satin Brass (US4), Satin Nickel (US15), and Unlacquered Brass (US3NL). Unlacquered Brass is a living finish, so it will patina with handling unless it is kept polished, which matters if you are trying to match other openings in a building that are already aged.

Finish and rosette are the two required choices, plus backset, offered as 2-3/8 inch or 2-3/4 inch. The 28 degree rotation latch is an optional upgrade over the standard latch, and there are free text fields for door thickness, a split finish request, and comments. Note that 2-3/8 inch is the usual residential interior backset and 2-3/4 inch the alternate, so measure from the door edge to the center of the bore before you pick.

Several knob products share the round silhouette but serve a different purpose. The Sargent 78-2875 is an outside knob only with B design for the 7800 Series, and the Sargent 28C-KNOB is exit device trim with knob and rose in entrance function for 1-3/4 inch doors, both of which mount to exit hardware rather than a standard bored door. The Imperial USA ED-BKL580 is likewise knob trim in storeroom function for the ED-500 Series. The Lockey 3830 is a mechanical keyless combination knob lock with auto-locking passage function for doors 1 3/16 to 2 inches. None of these are a decorative dummy pair.

The Emtek Orb dummy pair covers doors that do not latch, so the rest of the unit needs passage, privacy and entry functions. For a single-brand fit-out, Dexter C2000 covers passage, privacy, entry/office and classroom in Grade 2 ball knob for doors 1-3/8 to 1-3/4 inches, and Pamex Baron FTF covers passage, privacy and entrance/office at Grade 3 over the same thickness range. Schlage Residential F500 Plymouth with Georgian knob ships as a combo pack with adjustable backsets and dual strikes, and the Sure-Loc Bergen round knob comes as a 6-pack with adjustable backset for volume work.

The Emtek Orb knobset fits doors 1-3/8 to 2-1/4 inches thick with a standard 2-1/8 inch bore prep, and its Stretto rosette option requires a 1-1/4 inch bore with 2-hole prep for thumbturn privacy. If the door prep is not a match, the Kwikset 200P-CP Polo passage knob and the 400P-CP Polo keyed entry knob both ship with a round corner adjustable latch and round corner strike, the 400P-CP rated Grade 3 for doors 1-3/8 to 1-3/4 inches. Sure-Loc Bergen also offers an adjustable backset.

Brass, both the material and the substrate, and it belongs to Emtek's Brass collection. The styling is contemporary rather than traditional, which is why it reads as a modern round knob rather than an egg or colonial shape like the Omnia 434 or Baldwin 5011.

Tubular. It works in a standard bored door prep rather than a mortise pocket, so no routing of the door edge for a lock case is involved.

No. It is entirely mechanical, non-electronic, and non-keyed, so there is nothing to wire, program, or batter y-change. For keyless mechanical access control on an exterior door, a combination unit like the Lockey 3830 is the different product category you would be looking at.
