Emtek Designer Brass Crystal Knobsets - Diamond Knob, Dummy (Pair)

No door prep is needed. The Diamond crystal knob dummy pair is surface mounted, so it screws to the face of the door with no 2-1/8 inch cross bore or latch bore. That makes it the usual choice for a closet door, a false or inactive leaf of a double door, or a pantry door with a ball catch or magnetic catch doing the holding.

Yes. The Diamond crystal knob set is rated for doors 1-3/8 inch to 1-3/4 inch thick, which covers the standard commercial 1-3/4 inch leaf and the common 1-3/8 inch interior door.

No, and that is the point of the function. A dummy knob does not turn and has no latch or spindle behind it, so it is a pull only. If the door needs to stay closed you need a catch (roller, ball, or magnetic) or a different function. For a door that has to latch but not lock, a passage set is the right call instead, such as the Corbin Russwin CK4410 passage/closet knob or the Dexter C2000 passage knob.

It ships as a pair, one knob for each face of the door, sold as a complete set with both rosettes. If you only need a single knob on one face, this is not the configuration you want; a single dummy trim such as the Schlage A170 or the BEST 6K single dummy covers that.

The Emtek Diamond crystal knobset is dummy function and surface mounts with no door prep, so it does not latch. For a latching non-keyed knob on the same 1-3/8 inch to 1-3/4 inch door range, the Corbin Russwin CK4410 is a Grade 2 passage/closet cylindrical knob lock, the Dexter C2000 passage ball knob is Grade 2, and the Pamex FTF30 Baron is a Grade 3 passage knob lockset. For a decorative brass passage knob, the Omnia 434/PA egg-shaped knob latchset is solid brass, and the Baldwin Estate 5011 Colonial passage knob comes with the 5058 rose.

No - it is a non-keyed dummy set with no latch or turn, so it cannot secure a bedroom or bath. For privacy function, options include the Dexter C2000 privacy ball knob in Grade 2, the Cal-Royal BER20 Grade 3 privacy knob lock with brass trim, the Pamex FTF10 Baron Grade 3 privacy knob lockset, the Deltana 6112 St. Thomas privacy knob for 1-3/8 inch to 2 inch doors, and the Baldwin Estate 5077 Bethpage privacy knob with R027 rose.

The Emtek Diamond crystal knobset covers doors 1-3/8 inch to 1-3/4 inch. For thicker doors, the Corbin Russwin CK4310 Grade 1 passage/closet knob lock and the Deltana 6171 Round Knob entry both cover 1-3/8 inch to 2 inch, the Deltana 3381 Egg Knob entry covers the same range, and the Falcon X101 Grade 1 heavy duty passage knobset covers 1-3/8 inch to 2-1/4 inch.

Three rosette styles, Rope, Lancaster, and Ribbon and Reed, each available in seven finishes: Oil Rubbed Bronze (US10B), Satin Nickel (US15), Pewter (US15A), Polished Chrome (US26), Polished Brass Lifetime (US3), Unlacquered Brass (US3NL), and French Antique (US7). Emtek also allows any brass rosette from the line, so if you want a plate that is not one of the three shown, it can be ordered that way.

Yes. A split finish option is available at order entry, so the hall side and the room side can be specified differently, which is common when a hallway is chrome and a bedroom is unlacquered brass. Enter the two finishes you want in the split finish field.

It is a residential product. The Diamond crystal knob is a decorative glass knob on a brass base, part of Emtek's Glass and Porcelain collection, and carries no commercial duty rating. For office, school, or multi-family corridor use, go to a graded cylindrical lock like the Grade 1 Corbin Russwin CK4310 or the Grade 1 Schlage D10S passage.

Yes, that is the normal way Emtek's Diamond crystal knobs get specified. Use this dummy pair on closet and inactive double-door leaves where nothing needs to latch, and order the same Diamond knob in passage or privacy function for the bedrooms and baths. Keep the rosette style and finish the same across all of them and they read as one set. Note this dummy set is non-keyed, so it plays no part in any keying scheme.

Several knob items in the same aisle are not interchangeable with the Emtek Diamond dummy pair. 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 for 1-3/4 inch doors - both are trim for exit devices, not standalone door knobs. The Imperial USA ED-BKL580 is knob trim in storeroom function for the ED-500 Series. Keyed sets such as the Kwikset 400P-CP Grade 3 keyed entry knob and the Corbin Russwin CK4851 entrance/office lock serve an entirely different function than a non-keyed dummy.

The knob is glass with solid brass rosettes and base, which is why any brass rosette in the Emtek line will mate with it. Unlacquered Brass (US3NL) is a living finish, so it will darken and patina with handling rather than staying bright; Polished Brass Lifetime (US3) is the option that stays as delivered.

The Emtek Diamond crystal knobset is sold as a complete set for a single door opening. For volume standardization, the Sure-Loc Bergen round knob is offered as a 6-pack with adjustable backset, and the Schlage Residential F500 Plymouth with Georgian knob is a combo pack with adjustable backsets and dual strikes for doors 1-3/8 inch to 1-3/4 inch.
