Emtek 8207.CK.US15 – Frequently Asked Questions
1) Will the Emtek Diamond crystal privacy knob fit a standard 2-1/8 inch bored door?
Yes. The Diamond crystal knob privacy set drops into standard door prep with a 2-1/8 inch cross bore, and the standard latch is set for a 2-3/8 inch backset with 2-3/4 inch available if your existing holes are bored deeper. One exception on the rosette: the STRETTO rosette needs a 1-1/4 inch diameter bore and a 2-hole door prep for the thumbturn privacy.
2) What door thickness does the Emtek Diamond privacy knobset work on?
The spec sheet lists 1-3/8 inch to 1-3/4 inch, which covers standard interior and commercial door thickness. Emtek also states the set fits any door between 1-3/8 inch and 2-1/4 inch with standard 2-1/8 inch bore prep, so thicker slabs up to 2-1/4 inches are accommodated. If your door is thicker than 1-3/4 inches, enter the actual thickness in the Door Thickness field when ordering so the correct spindle and screws come with it.
3) Is a latch and strike plate included with the Emtek Diamond knob privacy set, or do I order those separately?
It ships as a complete set: both knobs, the rosettes, the latch and the strike plate. Nothing else is needed to hang it on a pre-bored door. The latch faceplate can be had round corner or square corner to match the mortise already cut in your edge.
4) What is the difference between the standard latch, the 28 degree latch, and the CF mechanism on Emtek knobsets?
Three choices. Standard latch is the conventional tubular latch. The 28 Degree Rotation Latch reduces how far you have to turn the knob to retract the bolt, which suits glass knobs where a full rotation is awkward to grip. The CF Mechanism gives you rosettes with no exposed screws for a cleaner face, and it comes with the 28 degree latch included. Pick CF if the appearance of the rose matters on the finished opening.
5) Is this Emtek crystal knob keyed, and how does the privacy function lock?
Non-keyed. It is a privacy/bed/bath function, so it locks from the inside by thumbturn or button and has no cylinder or key on the outside. That is what you want on a bedroom or bathroom door. If you need a keyed opening, a privacy set is the wrong function.
6) Can I use this Emtek glass knob set on commercial office or school doors?
No. The Diamond crystal knobset is classified residential, and it is a tubular bored lockset with a glass knob, no ANSI grade behind it. For commercial traffic look at a graded cylindrical knob lock instead, like the Grade 1 Corbin Russwin CK4310 passage or the Grade 2 Dexter C2000 privacy, which is the commercial equivalent of this function.
7) How do I know whether to order the 2-3/8 or 2-3/4 inch backset for an existing door?
Measure from the edge of the door to the center of the bore hole. 2-3/8 inches is the usual residential dimension and is what the standard latch is supplied for; 2-3/4 inches is the other common backset and must be specified on the order. Backset is a required selection, so you have to pick one either way.
8) What is the closest decorative brass privacy knob to the Emtek Diamond crystal knob privacy set?
For a decorative solid brass privacy knob in the same residential bed and bath role, the Baldwin Estate 5077 Bethpage privacy knob with R027 rose and the Deltana 6112 St. Thomas privacy knob are the nearest peers. The Deltana 6112 covers doors 1-3/8 inch to 2 inch. The difference is the knob itself: the Emtek Diamond is a faceted glass and porcelain collection knob on a brass rosette, while the Baldwin and Deltana options are metal knobs.
9) I need a privacy knob with an ANSI grade for a multi-family bed and bath door - what should I use instead of the Emtek Diamond crystal knob?
Use a graded cylindrical privacy knob. The Dexter C2000 Series privacy ball knob is Grade 2 and fits doors 1-3/8 inch to 1-3/4 inch; the Cal-Royal BER20 privacy knob is Grade 3 with brass trim over the same thickness range; the Pamex FTF Baron privacy knob is Grade 3 for 1-3/8 inch to 1-3/4 inch doors. The Emtek Diamond is a residential decorative set, so on openings where a grade is called out on the spec, one of those three answers the requirement.
10) The Emtek Diamond crystal knob is non-keyed - what do I order for an exterior or office door that needs a key?
Move to a keyed function. The Deltana 3381 Egg knob entry and 6171 Round knob entry both cover 1-3/8 inch to 2 inch doors in an entry function; the Cal-Royal BER00 is a Grade 3 entrance/office knob with a Kwikset keyway; the Kwikset 400P-CP Polo keyed entry knob is Grade 3 for 1-3/8 to 1-3/4 inch doors. The Emtek Diamond set is a non-keyed privacy function and will not accept a cylinder.
11) Will the Emtek Diamond privacy knob work on a commercial fire-rated door?
It is built as residential decorative hardware. For a fire-rated opening, comparables that carry a fire rating include the Falcon W101 Grade 2 cylindrical knob lock, passage/closet function with a 2-3/4 inch backset, and the Falcon X101 Grade 1 heavy duty passage knobset for 1-3/8 inch to 2-1/4 inch doors. Both are passage functions, so for a rated bed or bath opening you would specify a graded privacy lock instead.
12) Which rosettes can I get with the Emtek Diamond crystal knob?
Lancaster, Ribbon and Reed, and Rope rosettes are the configured options, and the knob can be ordered with any Emtek brass rosette if you are matching an existing style elsewhere in the house. All three are brass, the same substrate as the knob assembly.
13) What are the decorative alternatives if I want a solid brass privacy knob instead of a glass one?
Two close alternatives in the same decorative category: 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. Both are metal knobs in a privacy function rather than crystal, so they pair better with an all-metal hardware program.
14) I need matching passage knobs for the hall and closet doors to go with these bathroom sets. What should I look at?
Stay within the Emtek Glass and Porcelain collection and order the Diamond knob in a passage function with the same rosette and finish, so the doors read as one program. If you are willing to switch to a metal knob for the secondary doors, the Baldwin Estate 5000 Baltimore passage knob comes preconfigured with a 2-3/8 inch backset, the same backset this crystal set ships with as standard.
15) Can I use a dummy knob in place of the Emtek Diamond privacy set on a closet or inactive door?
Only where nothing needs to latch. Single dummy trim such as the BEST 6K Series dummy, the Schlage A170 single dummy trim, or the Omnia 458/0 single dummy latchset mounts a knob with no latch or lock mechanism behind it. The Emtek Diamond privacy set is a complete tubular lockset sold with latch and strike plate and a locking thumbturn, so a dummy is not a substitute on any door that must stay closed or lock.
16) My door is thicker than 1-3/4 inch - which knob locks cover it if the Emtek Diamond standard spec does not?
The Emtek Diamond crystal knob privacy set is published at 1-3/8 inch to 1-3/4 inch on the specification list, with an ordering note covering doors up to 2-1/4 inch with standard 2-1/8 inch bore prep, and a door thickness field is available at order. Among comparables built for thick doors, the Falcon X101 Grade 1 passage knobset covers 1-3/8 inch to 2-1/4 inch, and the Corbin Russwin CK4310 Grade 1 passage knob covers 1-3/8 inch to 2 inch. Those are passage functions, not privacy.
17) I need matching passage and privacy knobs on the same suite of doors - can I mix the Emtek Diamond with a builder combo pack?
The knob styles will not match. A combo pack such as the Schlage Residential F500 Plymouth with Georgian knob, which covers 1-3/8 inch to 1-3/4 inch doors with adjustable backsets and dual strikes, gives you one knob design across functions but in its own Georgian style. To keep the Emtek Diamond look across a suite, stay within the Emtek Diamond knob in the matching passage function and hold the same rosette and finish, which includes Polished Brass Lifetime, Satin Nickel, Oil Rubbed Bronze, Polished Chrome, Pewter, French Antique and Unlacquered Brass.
18) What holds up better on a high-traffic institutional bathroom door than the Emtek Diamond crystal knob?
Step up to a heavy duty cylindrical platform. The Schlage D Series D10S passage knob is Grade 1 heavy duty, the BEST 8K Series is Grade 1 heavy duty in an entrance function, and the Sargent 8XG04 is a Grade 1 heavy duty storeroom knob lock with a 2-3/4 inch backset. The Emtek Diamond is a residential tubular privacy set with a glass knob, better suited to interior residential doors than continuous institutional traffic.
