Emtek 8100.CK.US15 – Frequently Asked Questions

1) Does the Emtek Diamond crystal passage knob fit a standard 2-1/8 inch bored door?
Yes. The Diamond crystal knobset mounts in the standard bored prep with a 2-1/8 inch cross bore, so an existing door drilled for a common residential knob takes it without new boring. One exception: if you pick the STRETTO rosette, that one needs a 1-1/4 inch diameter bore and a 2-hole prep for the thumbturn privacy version.
2) What backset do I order for an Emtek Diamond knob passage set?
Backset is a required choice at order time, 2-3/8 inch or 2-3/4 inch. Measure from the door edge to the center of the bore hole: 2-3/8 is typical on residential interior doors, 2-3/4 shows up on heavier or commercial-style openings. The standard latch supplied is 2-3/8 inch, so you have to specify 2-3/4 if that is what your door is prepped for.
3) Does a passage knob lock, or do I need a privacy set for a bedroom?
Passage means no lock at all. The Diamond crystal knobset is non-keyed with a passage function, so both knobs always turn and the latch just holds the door shut. That is what you want on a hall, closet, or pantry door. For a bedroom or bath you need a privacy set with a thumbturn instead.
4) Can I use the Emtek Diamond passage knob on a commercial corridor or classroom door?
No. The Emtek Diamond Classic Brass Crystal knob is a residential passage set with no grade rating stated for commercial use. For commercial openings, the Schlage D10S passage latch is a Grade 1 heavy duty cylindrical non-keyed knob lock with the Orbit knob, and the Falcon X101 is a Grade 1 heavy duty cylindrical passage knobset that is fire rated and fits doors 1-3/8 inch to 2-1/4 inch. In Grade 2, the Corbin Russwin CK4410 Global knob passage/closet lock covers 1-3/8 inch to 1-3/4 inch doors and the Falcon W101 is a fire rated Grade 2 passage/closet knob lock with a 2-3/4 inch backset.
5) What is a comparable solid brass passage knob if the Emtek Diamond crystal knob is not the look we want?
The Emtek Diamond Classic Brass Crystal passage set is a residential, non-keyed passage knob in brass with a glass knob. For a solid brass passage knob in a traditional metal shape instead of crystal, the Omnia 434/PA is a traditional egg-shaped knob latchset in solid brass with a 3 inch projection, and the Baldwin Estate 5011 Colonial passage knob with 5058 rose is a passage/hall/closet function knob. The Baldwin Estate 5000 preconfigured Baltimore knob with 5048 rose is a passage lock supplied with a 2-3/8 inch backset and full lip strike, while the Emtek set lets you pick 2-3/8 inch or 2-3/4 inch backset.
6) I need the same look but for a bedroom or bathroom door that locks. What should I order instead of the Diamond passage set?
The Emtek Diamond Classic Brass Crystal set is passage function and non-keyed, so it always latches without locking. For a bed or bath door, privacy knobs in comparable decorative lines include the Baldwin Estate 5077 Bethpage privacy knob with R027 rose, the Baldwin Estate 5000 Baltimore privacy knob with 5148 rose and 2-3/8 inch backset, and the Deltana 6112 St. Thomas privacy knob for doors 1-3/8 inch to 2 inch. Note the Emtek description calls out that a STRETTO rosette needs a 1-1/4 inch bore and 2-hole door prep for thumbturn privacy.
7) What comes in the box with the Emtek crystal Diamond knob set?
It ships as a complete set: two crystal Diamond knobs, the rosettes you select, the latch, and the strike plate. Nothing else is needed to hang it on a pre-bored door. The latch faceplate is available in round corner or square corner to match the mortise already cut in your door edge.
8) What is the CF Mechanism option on Emtek knobsets and should I choose it?
CF stands for the concealed-fastener build: the rosettes mount with no exposed screws, so you see a clean brass ring on the door face instead of two screw heads. Choose it when the hardware is a visible design feature. The CF option includes the 28 degree rotation latch. The other two choices are the standard latch or the 28 degree rotation latch on its own with conventional screwed rosettes.
9) Can I mix and match the rosette shape on an Emtek Diamond crystal knob?
Yes. The Diamond crystal knob can be ordered on any brass rosette in the line: #8, Oval, Quincy, Rectangular, Regular, Watford, or Wilshire. That is how you match knobs on a remodel to trim that is already in the house, square rosettes with square casing, oval or round with traditional millwork.
10) What finishes do Emtek Classic Brass crystal Diamond knobsets come in?
Ten: Flat Black (US19), French Antique (US7), Oil Rubbed Bronze (US10B), Pewter (US15A), Polished Brass Lifetime (US3), Polished Chrome (US26), Polished Nickel Lifetime (US14), Satin Brass (US4), Satin Nickel (US15), and Unlacquered Brass (US3NL). The knob itself is glass; the finish applies to the brass rosette and trim. Unlacquered brass will patina over time, the Lifetime finishes will not. There is also a split finish field if you need one face different from the other, say a black hall side with polished nickel inside a bath.
11) What is a lower-cost passage knob that uses the same 2-1/8 inch bore and adjustable backset as the Emtek Diamond set?
The Emtek Diamond crystal passage set uses standard 2-1/8 inch cross bore prep with a 2-3/8 inch or 2-3/4 inch backset. Simpler passage knobs on that same standard bored prep include the Dexter C2000 Grade 2 passage cylindrical ball knob, non-clutching and non-keyed, for doors 1-3/8 inch to 1-3/4 inch; the Pamex FTF Baron Grade 3 passage knob lockset for the same door range; the Arrow MK01 and RK01 Grade 2 passage knob locks, also 1-3/8 inch to 1-3/4 inch; and the Kwikset 200P Polo passage knob supplied with a 6AL latch and RCS round corner strike. These are plain metal knobs rather than faceted crystal on a brass rosette.
12) Is a dummy knob the same thing as the Emtek Diamond passage set?
No. The Emtek Diamond Classic Brass Crystal passage set is a complete tubular lockset that includes a latch and strike plate and turns to retract the latch. A dummy knob is surface-mounted trim with no latch at all, used on inactive or closet doors. Dummy options include the Omnia 434/0 traditional egg-shaped single dummy, the Omnia 442/00 single dummy knob latchset with a 2-5/8 inch rose, the Schlage A170 Grade 2 single dummy trim, and the Cal-Royal BA40 Barrington dummy knob for 1-3/8 inch to 1-3/4 inch doors. Order the dummy only where no latching is needed.
13) Do I have to tell you my door thickness when ordering an Emtek Diamond knobset?
There is a door thickness field on the order and it is worth filling in. Standard residential doors are 1-3/8 inch interior and 1-3/4 inch for heavier or exterior-weight slabs; if yours is thicker than normal, note the measurement so the set is built with the right spindle length. Measure the slab edge, not the frame.
14) I need matching passage knobs for a whole floor of units. Is the Emtek Diamond set the practical choice or is there a multi-pack?
The Emtek Diamond Classic Brass Crystal passage set is ordered per opening, with finish, rosette style and latch selected individually, which suits a decorative match on a unit-by-unit basis. If you are standardizing a run of doors on a single plain knob, the Sure-Loc Bergen round knob is offered as a 6-pack with an adjustable backset. Emtek finishes run Flat Black US19, Oil Rubbed Bronze US10B, Polished Chrome US26, Satin Nickel US15 and others, so matching existing brass or nickel trim is usually possible within the Emtek line.
