Emtek 7108.MSC.FB – Frequently Asked Questions
1) Does the Emtek Modern Square crystal knob passage set come with the latch and strike, or do I order those separately?
It ships as a complete set with the latch and the strike plate included, so you get both knobs, the rosettes you select, the latch and the strike in one order. The latch faceplate is available with round or square corners to match the mortise already cut in your door edge.
2) What is a passage knob set and will it lock?
Passage function means it latches but never locks. There is no key and no thumbturn on the Modern Square crystal knob set, so both knobs always retract the latch. It is what you use on hallway, closet and pantry doors. For a bath or bedroom that needs to lock from inside, you want a privacy set instead, and for a keyed door an entry set.
3) Will the Emtek Modern Square knob set fit my existing door prep?
It drops into standard residential door prep with a 2-1/8 inch cross bore. The latch is adjustable for either a 2-3/8 inch or 2-3/4 inch backset, and backset is a required selection when you order, so measure from the door edge to the center of the bore before you pick. If you are replacing a builder knob on a pre-bored door, no new boring is needed.
4) What is a commercial-grade alternative to the Emtek Modern Square crystal passage knobset for a high-traffic opening?
The Emtek Modern Square crystal knob passage set is a residential tubular passage knobset in brass. For a commercial opening, the Schlage D10S Orbit knob is a Grade 1 heavy duty cylindrical passage latch, and the Corbin Russwin CK4310 with Global knob is a Grade 1 passage/closet cylindrical lock covering doors 1-3/8 inch to 2 inch thick. Falcon X101 is another Grade 1 heavy duty cylindrical passage knobset, fire rated, for doors 1-3/8 inch to 2-1/4 inch.
5) What keyed entry knob can I use where the Emtek Modern Square passage set will not work?
The Emtek Modern Square crystal knobset is non-keyed, so it cannot secure an entry door. Keyed options include the Kwikset 400P-CP Polo keyed entry knob, Grade 3, for doors 1-3/8 inch to 1-3/4 inch; the Corbin Russwin CK4851 entrance/office cylindrical lock with conventional cylinder for doors 1-3/8 inch to 2 inch; and the Deltana 6171 Round knob entry set for doors 1-3/8 inch to 2 inch.
6) What looks like a passage knob substitute but will not latch the door?
Dummy trim is the common mix-up. The Emtek Modern Square crystal knobset is a passage set sold complete with latch and strike plate, so the knob turns and retracts a latch. The Schlage A170 single dummy trim, the BEST 6K single dummy trim, the Omnia 442/00 single dummy latchset with 2-5/8 inch rose, and the Bravura Biloxi dummy knobset are all dummy function - surface-mounted pulls with no latching action. Order those only for inactive or closet door faces.
7) My door is thicker than 1-3/4 inch - which knob locks cover that?
The Emtek Modern Square crystal passage knobset fits doors 1-3/8 inch to 2-1/4 inch thick with a 2-1/8 inch bore standard prep. Comparable knob locks that also reach past 1-3/4 inch include the Falcon X101 Grade 1 passage knobset at 1-3/8 inch to 2-1/4 inch, the Corbin Russwin CK4310 Grade 1 passage lock at 1-3/8 inch to 2 inch, and the Deltana 6901 Portland knob, which is limited to 1-3/8 inch to 1-3/4 inch.
8) What should I use for a storeroom or closet door that needs to stay locked, since the Emtek passage set always turns free?
The Emtek Modern Square crystal knobset is a passage function, so both knobs always retract the latch. For a storeroom door, the Sargent 6G04 is a Grade 2 standard duty storeroom/closet knob lock with a single cylinder, the Sargent 8XG04 is the Grade 1 heavy duty storeroom/closet version with a 2-3/4 inch backset, and the BEST 8K is a Grade 1 heavy duty entrance function single cylinder knob lock.
9) What is the CF mechanism option on Emtek knobsets and should I choose it?
CF mechanism gives you rosettes with no exposed screws, so the trim face is clean on both sides. It comes with the 28 degree rotation latch. The other two choices are the standard latch or the 28 degree rotation latch on its own, both of which use conventional screw-through rosettes. Pick CF if the visible screw heads bother you on a feature door; pick the standard latch for the simplest install.
10) Which rosettes and finishes can I get with the Emtek crystal Modern Square knob?
Five rosette styles are offered, #1, #2, #3, #4 and #6, and the set can be ordered with any Sandcast Bronze rosette. Finishes are Flat Black Bronze (FB), Medium Bronze (MB) and Tumbled White Bronze (TWB). There is also a split finish field on the order form if you want the interior and exterior trim finished differently.
11) I need matching bathroom and bedroom hardware to go with these passage knobs. What else could I use?
For a suited look, Emtek offers the same Modern Square crystal knob in a privacy configuration, so the hallway doors take the passage set and the bath and bedroom doors take privacy. If you want a different brand look in the same decorative class, the Baldwin Estate 5077 Bethpage privacy knob and the Deltana 6112 St. Thomas privacy knob are both privacy function knobsets, and Baldwin's Estate 5000 Baltimore passage knob with 5048 rose is a preconfigured passage set with a 2-3/8 inch backset.
12) Do I need a special door prep for the STRETTO rosette?
Yes. The STRETTO rosette needs a 1-1/4 inch diameter bore hole rather than the usual 2-1/8 inch cross bore, and on a privacy version it also needs a two-hole door preparation for the thumbturn. Every other rosette works with standard prep.
13) Is there a simpler brass passage knob set if I do not need the crystal knob or rosette choices?
The Emtek Modern Square set pairs a crystal knob with a choice of five rosettes and three bronze finishes. If you only need a plain brass passage latchset, the Omnia 434/PA is a solid brass egg-shaped knob latchset with a 3 inch projection, and the Baldwin Estate 5011 Colonial passage knob with 5058 rose is a fixed knob and rose pairing. The Baldwin Estate 5000 Baltimore passage set comes preconfigured with a 2-3/8 inch backset and full lip strike.
14) Which passage knobsets besides the Emtek Modern Square also offer a 2-3/4 inch backset?
The Emtek Modern Square crystal passage set is ordered with either a 2-3/8 inch or 2-3/4 inch backset. Among other passage knobsets, the Falcon W101 Grade 2 cylindrical knob lock is a passage/closet latch function supplied with a 2-3/4 inch backset, and the Baldwin Estate 5000 Baltimore passage set is preconfigured at 2-3/8 inch.
15) What Grade 2 or Grade 3 passage knobsets compare to the Emtek Modern Square for multi-family interior doors?
The Emtek Modern Square crystal knobset is a brass residential passage set. Graded alternatives for interior doors include the Arrow MK01 and RK01 Grade 2 non-keyed passage cylindrical knob locks for doors 1-3/8 inch to 1-3/4 inch, the Dexter C2000 Grade 2 passage ball knob over the same thickness range, the Corbin Russwin CK4410 Grade 2 passage/closet lock, and the Pamex FTF Baron Grade 3 passage knob lockset.
16) Is there a keyless combination knob option instead of the Emtek Modern Square passage knob?
The Emtek Modern Square crystal knobset is non-electronic and non-keyed passage function. If you need coded access at the knob, the Lockey 3830 is a mechanical keyless combination knob lock with auto-locking passage function for doors 1 3/16 inch to 2 inch thick.
17) I need to outfit several interior doors at once - is there a multi-pack knob alternative?
The Emtek Modern Square crystal knobset is ordered as a single complete set with latch and strike plate. For volume interior work, 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.
18) What does the 28 degree rotation latch actually change?
It shortens how far you have to turn the knob to retract the latch, which suits a small square crystal knob where there is less to grip than on a round ball knob. You can order it on its own or get it bundled with the CF mechanism; the third option is the standard latch.
19) Is this a tubular lockset or a mortise lock?
Tubular, bored into the face of the door through a 2-1/8 inch cross bore. It is not a mortise lock, so you do not need a pocket cut into the door edge, only the standard latch mortise for the faceplate.
