Emtek 8200.CK.US15 – Frequently Asked Questions
1) Will the Emtek Diamond crystal privacy knob fit my existing 2-1/8 inch bored door?
Yes. The Emtek Diamond crystal knob privacy set drops into standard door prep with a 2-1/8 inch cross bore, and the latch is adjustable for either a 2-3/8 or 2-3/4 inch backset. One exception on rosette choice: the STRETTO rosette needs a 1-1/4 inch diameter bore and a 2-hole door prep for the thumbturn privacy, so it is not a straight drop-in to a single standard bore.
2) What door thickness does this Emtek crystal knob privacy set work on?
The specification table for the Diamond crystal knobset lists 1-3/8 inch to 1-3/4 inch door thickness, which covers standard interior doors and commercial 1-3/4 inch leaves. If your door is thicker than that, note it in the Door Thickness field when you order so the spindle and screw pack are set for it.
3) Is this a keyed lock or just a bed and bath privacy set?
Privacy only, non-keyed. The Diamond crystal knobset is a tubular bed/bath function, so it locks from the inside with a thumbturn and has no key cylinder. For a room that needs a key, you want an entry or keyed-function knobset instead.
4) What comes in the box with the Emtek Diamond knob privacy set?
It ships as a complete set: both crystal Diamond knobs, the rosettes you select, the latch, and the strike plate. Nothing else is needed for a door already bored 2-1/8 inch. Latch faceplates come round corner or square corner to match the existing mortise in the door edge.
5) Is this Emtek crystal knobset suitable for a commercial corridor or apartment turn?
It is a residential product, brass and glass, non-graded, and better suited to homes, model units, boutique hospitality and high-end interior doors. For rated commercial traffic on a bed/bath door, look at a graded cylindrical privacy set instead, such as the Dexter C2000 Grade 2 privacy knob or the Cal-Royal BER20 Grade 3 privacy knob, both listed for 1-3/8 to 1-3/4 inch doors.
6) What should I use instead of the Emtek Diamond privacy knobset on a commercial or high-traffic opening?
The Emtek Diamond crystal privacy set is specified for residential use. For heavier-traffic openings, the Dexter C2000 Series privacy cylindrical ball knob lock is Grade 2 for doors 1-3/8 inch to 1-3/4 inch thick, and if the opening needs a keyed function instead the Sargent 8XG04 is a Grade 1 heavy duty storeroom knob lock with a 2-3/4 inch backset.
7) Which knobsets look like substitutes for the Emtek Diamond privacy set but will not lock a bathroom door?
Watch the function. The Emtek Diamond crystal set is a privacy/bed/bath knobset with a thumbturn, so passage and dummy knobs are not interchangeable with it: the Baldwin Estate 5000 Baltimore knob with 5048 rose is passage function, the Omnia 434/PA egg-shaped knob latchset is passage, and the Omnia 458/0 and Bravura Biloxi are single dummy knobs with no latch action at all.
8) What is the CF mechanism option on Emtek knobsets and should I pick it?
CF means concealed fastener: the rosettes mount with no exposed screws, which is the cleaner look on a feature door. Choosing CF also brings the 28 degree rotation latch with it. The other two latch choices are the standard latch and the 28 degree rotation latch on its own with conventional exposed-screw rosettes.
9) Which rosettes can I get with the Diamond crystal knob?
Seven rosette shapes are offered with the Diamond crystal knob: #8, Oval, Quincy, Rectangular, Regular, Watford and Wilshire. Any brass rosette in the line can be paired with this knob, so you can match rosette shape across passage, privacy and entry doors in the same house.
10) Can I match the Emtek crystal knob finish to the rest of my hardware?
Ten finishes are available: 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). If you need the interior and exterior rosettes in two different finishes, there is a Split Finish field on the order to spell that out.
11) What is a comparable decorative privacy knob if I do not want a glass knob?
Two metal-knob privacy sets of similar decorative intent: the Baldwin Estate 5077 Bethpage privacy knob with R027 rose, and the Deltana 6112 St. Thomas privacy knob, which is listed for 1-3/8 to 2 inch doors, a wider thickness range than the Emtek crystal set's 1-3/8 to 1-3/4 inch. Baldwin also offers a preconfigured Estate 5000 Baltimore privacy knob set on a 2-3/8 inch backset if you want a fixed configuration rather than choosing rosette and latch options.
12) Will the Emtek Diamond crystal knob match other Emtek glass knobs already on my doors?
The Diamond knob is part of Emtek's Glass and Porcelain collection in the American Classic theme, so it shares the same brass rosette shapes and finishes as the rest of that line. If you already have Emtek glass knobs on a set of doors, order the same rosette shape and finish code and the new privacy door will read as part of the same suite.
13) How does the Emtek Diamond crystal privacy knobset differ from a Grade 1 cylindrical knob lock?
They are built for different openings. The Emtek Diamond privacy set is a residential tubular brass knobset with a glass knob, adjustable to a 2-3/8 inch or 2-3/4 inch backset in a 2-1/8 inch cross bore. A Grade 1 cylindrical lock such as the Schlage D10S passage knob or the Corbin Russwin CK4310 passage/closet lock, which covers doors 1-3/8 inch to 2 inch thick, is a commercial-duty chassis with no decorative glass knob or rosette selection.
14) Is there a lower-cost privacy knob lock if the crystal Emtek knob is not needed?
Yes. The Pamex FTF Baron knob lockset in privacy function is a Grade 3 set for doors 1-3/8 inch to 1-3/4 inch thick, and the Cal-Royal BER20 privacy knob lock is Grade 3 with brass trim over the same door thickness range. Both are plain metal knobs rather than the glass knob and brass rosette construction of the Emtek Diamond privacy set.
15) I need a keyed entry knob to match the bedroom doors where I am using the Emtek Diamond privacy set. What are the options?
The Emtek Diamond crystal privacy set is non-keyed, so a keyed opening needs a different product. Deltana's 3381 Egg knob and 6171 Round knob are both entry function for doors 1-3/8 inch to 2 inch thick, the Kwikset 400P-CP Polo keyed entry knob is Grade 3 for 1-3/8 inch to 1-3/4 inch doors, and the Cal-Royal BER00 is a Grade 3 entrance/office knob lock with a Kwikset keyway.
16) Is there a fire-rated alternative to the Emtek Diamond crystal privacy knobset?
For an opening that calls for a fire-rated knob lock, the Falcon W101 is a Grade 2 medium duty cylindrical knob lock with a fire rating and a 2-3/4 inch backset in passage/closet function, and the Falcon X101 is a Grade 1 heavy duty fire-rated passage knobset for doors 1-3/8 inch to 2-1/4 inch thick. Both are passage function rather than the privacy/bed/bath function of the Emtek Diamond set.
