Emtek 8107.CK.US15 – Frequently Asked Questions

1) Will the Emtek Diamond crystal passage knob fit a standard 2-1/8 inch bored door?
Yes. The Diamond crystal knob passage set drops into standard door prep: a 2-1/8 inch cross bore, with the latch set for either a 2-3/8 or 2-3/4 inch backset. One caveat on rosette choice, the STRETTO rosette needs a 1-1/4 inch diameter bore and a 2-hole prep. The rosettes offered with this knob are Lancaster, Ribbon & Reed and Rope, so a standard single-bore prep covers it.
2) Do I have to specify the backset when ordering the Emtek Diamond crystal knob?
Yes, backset is a required choice. The standard latch ships for a 2-3/8 inch backset, which is what most residential interior doors use. Measure from the door edge to the center of the bore hole; if it comes out at 2-3/4 inches you must select that instead or the knob will not line up with the existing hole.
3) Does a passage knob lock? What is the difference between passage and privacy on an Emtek crystal knob?
Passage does not lock and takes no key. The Diamond crystal knobset in passage function is a latch only, both knobs always turn, which is what you want on a hallway, closet or a door between rooms. For a bedroom or bath you need the privacy version with a thumbturn instead, and for an exterior or office door you need a keyed function. Nothing about the passage set can be converted to lock later.
4) Is the Emtek crystal Diamond knob suitable for a commercial building or an apartment turnover package?
This one is built for residential use, a decorative glass knob on a brass tubular latch. For a rental fleet, a school corridor or anywhere the door gets hammered daily, go to a graded cylindrical lock instead: the Schlage D10S is a Grade 1 passage knob, and the Corbin Russwin CK4310 is Grade 1 with a 1-3/8 to 2 inch thickness range. If you want a middle option, the Arrow MK01 and the Dexter C2000 passage knob are both Grade 2 for 1-3/8 to 1-3/4 inch doors.
5) The door is 2 inches thick - will an Emtek Diamond passage knob work, or do I need something else?
The Diamond passage set is specified for doors 1-3/8 inch to 1-3/4 inch thick with a 2-1/8 inch cross bore. For a 2 inch door, the Corbin Russwin CK4310 Grade 1 passage/closet lock covers 1-3/8 inch to 2 inch, the Deltana 6171 Round Knob entry covers 1-3/8 inch to 2 inch, and the Falcon X101 Grade 1 heavy duty cylindrical passage knobset covers 1-3/8 inch to 2-1/4 inch.
6) I need a fire rated passage knob - can I use the Emtek Diamond crystal knob?
The Diamond crystal knob is a residential brass knobset. Where the opening carries a fire rating requirement, the Falcon W101 is a Grade 2 medium duty cylindrical knob lock with a passage/closet latch function, 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, a fire rating, and coverage for 1-3/8 inch to 2-1/4 inch doors.
7) What is a commercial-grade alternative to an Emtek Diamond crystal passage knob for a hallway door that sees heavy traffic?
The Emtek Diamond crystal knob is a brass passage knobset built for residential use. Where the opening needs a commercially graded passage knob instead, the Schlage D10S is a Grade 1 heavy duty cylindrical non-keyed knob lock with an Orbit knob in the D Series, and the Corbin Russwin CK4310 is a Grade 1 passage/closet cylindrical lock with a Global knob that covers doors 1-3/8 inch to 2 inch thick. Both trade the glass knob and decorative rosette for a metal knob and a graded cylindrical chassis.
8) I need the same crystal knob look on a bedroom door instead of a hall door - what do I use?
The Diamond crystal knob is a passage set, which is non-keyed and has no locking mechanism, so it will not serve a bedroom or bathroom door that needs to lock from inside. For a privacy function knob, the Dexter C2000 is a Grade 2 privacy cylindrical ball knob lock for doors 1-3/8 inch to 1-3/4 inch thick, the Baldwin Estate 5000 pairs a 2 inch Baltimore knob with a 5148 rose on a privacy lock with a 2-3/8 inch backset and full lip strike, and the Deltana 6112 St. Thomas is a privacy knob for doors 1-3/8 inch to 2 inch thick.
9) What is the CF mechanism option on Emtek knobs and should I pick it?
CF means the rosettes mount with no exposed screws, so you see a clean brass ring on the face of the door rather than two screw heads. It is the option to pick when the hardware is on show. Selecting CF also brings the 28 Degree latch, which is a shorter knob rotation than a standard latch. The other two choices are the 28 Degree latch on its own or the standard latch.
10) I only want a knob on one side of a closet door that does not latch. Is a passage set the right thing?
No. A passage set includes a working latch and a strike, and both knobs turn. For a false door, a closet door held by a ball catch, or the fixed leaf of a pair, you want a dummy knob instead, such as the Omnia 442/00 or 458/0 brass dummy latchsets, the Sure-Loc Bergen round knob, or the BEST 6K single dummy trim in a graded line.
11) What is the closest decorative brass passage knob to the Emtek Diamond if I do not want a glass knob?
For a solid brass decorative passage knob without the crystal, the Baldwin Estate 5000 Baltimore is a 2 inch knob on a 5048 rose with a 2-3/8 inch backset and full lip strike, the Baldwin Estate 5011 Colonial passage knob comes on a 5058 rose, and the Omnia 434/PA is a traditional egg-shaped knob latchset in solid brass with a 3 inch projection. All three are passage function like the Diamond set, with a metal knob in place of the glass one.
12) What passage knob should I use if the door needs to be keyed instead?
The Diamond crystal knob is non-keyed, so it takes no cylinder. Where the same opening needs a key, the Corbin Russwin CK4851 is a Grade 1 entrance/office cylindrical lock with a Global knob and a conventional cylinder covering 1-3/8 inch to 2 inch doors, the Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet single cylinder knob lock with a 2-3/4 inch backset, and the Sargent 6G04 is a Grade 2 standard duty storeroom/closet knob lock with a single cylinder.
13) What is a simpler passage knob than the Emtek Diamond for a rental unit closet door?
The Diamond set is a brass and glass knob ordered by finish, rosette, and latch type. Where the closet door only needs a plain working passage knob, the Kwikset 200P Polo passage knob ships as an interior hall/closet lock with a 6AL latch and RCS round corner strike, the Pamex FTF Baron is a Grade 3 passage knob lockset for 1-3/8 inch to 1-3/4 inch doors, and the Dexter C2000 is a Grade 2 non-clutching passage ball knob for the same thickness range.
14) What is a good passage knob to standardize a whole apartment building on instead of a decorative crystal knob?
The Diamond crystal knob is a residential decorative set. For repeating the same knob across many units, graded cylindrical passage knobs give a consistent chassis: the Arrow MK01 is a Grade 2 passage cylindrical knob lock, non-keyed, for 1-3/8 inch to 1-3/4 inch doors, the Arrow RK01 is a Grade 2 passage ball knob over the same range, and the Corbin Russwin CK4410 is a Grade 2 passage/closet cylindrical lock with a Global knob for 1-3/8 inch to 1-3/4 inch doors.
15) Can I order the Emtek Diamond knob as an entry set for a front door?
The Diamond crystal knob is built as a passage set and is non-keyed. For a knob that locks and keys at an entry door, the Kwikset 400P Polo knob is an entry door lock with a 6AL latch and RCS strike, the Deltana 6901 Portland is an entry knob for 1-3/8 inch to 1-3/4 inch doors, and the Schlage Residential F500 Plymouth with Georgian knob ships as a combo pack with adjustable backsets and dual strikes for the same thickness range.
16) Is the Emtek Diamond passage knob interchangeable with an exit device knob trim?
No. The Diamond set is a tubular bored lockset that mounts in a 2-1/8 inch cross bore with a 2-3/8 inch or 2-3/4 inch backset latch. Knob trim for an exit device is a different part that mounts to the device, not to a bored door prep - the Sargent 28C-KNOB is exit device trim with knob and rose in entrance function for 1-3/4 inch doors, 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 for the ED-500 Series. None of those substitute for a complete bored passage set.
17) What passage knob works if the room needs coded access rather than a free-turning knob?
The Emtek Diamond set is a non-keyed passage knob, so it always turns freely from both sides. Where the door needs a code, the Lockey 3830 is a mechanical keyless combination knob lock with an auto-locking passage function that fits doors 1 3/16 inch to 2 inch thick. It replaces the decorative crystal knob with a combination chassis on the outside.
18) Does the Emtek Diamond knob passage set need to be handed left or right?
No handing to specify. It is a non-keyed tubular passage latch with a knob on each side, so it works on a left or right hand door either way it is installed. The only fit decisions are backset, latch faceplate corner and door thickness.
19) What are the alternatives to the Emtek Diamond knob if I want a passage knob in a satin brass finish?
The Diamond crystal knob comes in French Antique (US7), Oil Rubbed Bronze (US10B), Pewter (US15A), Polished Brass Lifetime (US3), Polished Chrome (US26), Satin Nickel (US15), and Unlacquered Brass (US3NL). For a US4 satin brass passage knob, the Bravura Dallas with rectangle trim is a Grade 2 passage knobset supplied in US4 satin brass. Other passage knobsets in the Bravura line include the Albany and the Lynchburg, both Grade 2 with round trim.
