Emtek 7108.MDC.FB – Frequently Asked Questions

1) Will the Emtek Modern Disc passage knob fit my existing 2-1/8 inch bored door?
Yes. The Modern Disc crystal knob passage set drops into a standard 2-1/8 inch cross bore prep, and the spec range covers doors 1-3/8 inch to 1-3/4 inch thick. The description also notes it fits doors from 1-3/8 inch up to 2-1/4 inch with that standard 2-1/8 inch bore prep. One exception to watch: if you order the STRETTO rosette, that one needs a 1-1/4 inch diameter bore and a 2-hole prep for thumbturn privacy, so it is not the same hole pattern.
2) Do I need to order the 2-3/8 or the 2-3/4 inch backset for an Emtek Modern Disc knob set?
Measure from the door edge to the center of the bore hole. If that is 2-3/8 inches, take the standard latch; if it is 2-3/4 inches, which is common on thicker commercial-style doors and some entry slabs, specify the 2-3/4 backset. Backset is a required selection on the Modern Disc passage set, and the latch supplied is adjustable to either 2-3/8 or 2-3/4 inches.
3) What is a passage knob set and will it lock the bathroom door?
No, it will not. The Modern Disc crystal knob is a passage function set, which means it latches the door shut and turns freely from both sides with nothing to lock. It is non-keyed with no privacy turn. Use it on hallways, closets, and pantry doors. For a bath or bedroom you need a privacy set with a thumbturn, and for an exterior or office door you need a keyed entry set.
4) Is the Emtek Modern Disc crystal knob suitable for a commercial corridor or apartment common area?
It is classified residential, and it is a tubular latch with a glass knob, so it is not the part for high traffic commercial openings. For a corridor or common area passage door, look at a graded cylindrical knob instead: the Schlage D10S is Grade 1 heavy duty passage, the Corbin Russwin CK4310 is Grade 1 passage/closet for 1-3/8 to 2 inch doors, and the Arrow MK01 is a Grade 2 passage knob for 1-3/8 to 1-3/4 inch doors. Keep the Emtek for unit interiors and residential-spec work.
5) I need the same look as the Emtek Modern Disc passage knob but with a bathroom lock. What do I order?
The Emtek Modern Disc knobset in the Glass and Porcelain collection is a non-keyed passage function, so it has no locking mechanism. For a privacy function on a bed or bath door, decorative options 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 thick.
6) Which knobs look like a substitute for the Emtek Modern Disc passage set but will not latch the door?
Dummy trim knobs mount to the face of the door and do not operate a latch, so they will not replace the Emtek Modern Disc passage set, which is sold complete with latch and strike plate. Dummy units in the same knob category include the Schlage A170 single dummy trim, the BEST 6K single dummy trim, the Bravura Biloxi dummy knobset, the Cal-Royal BA40 dummy knob, and the Omnia 434/0 and 458/0 single dummy latchsets. Use these only on inactive or closet panels.
7) The Emtek Modern Disc passage knob is non-keyed. What keyed knob should I use on an exterior or office door instead?
The Emtek Modern Disc knobset is a non-keyed passage function with no cylinder. For a keyed opening, the Kwikset 400P-CP Polo keyed entry knob is Grade 3 for doors 1-3/8 inch to 1-3/4 inch, the Dexter C2000 entry/office ball knob is Grade 2 keyed, the Corbin Russwin CK4851 entrance/office knob lock uses a conventional cylinder for doors 1-3/8 inch to 2 inch, and the Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet knob lock with a 2-3/4 inch backset.
8) I need a fire rated passage knob for a rated door opening. Can I use the Emtek Modern Disc passage set?
The Emtek Modern Disc passage knobset is a residential tubular knobset. When a fire rated assembly is specified, the Falcon W101 is a Grade 2 medium duty cylindrical passage/closet knob lock with a 2-3/4 inch backset and a fire rating, and the Falcon X101 is the Grade 1 heavy duty fire rated passage knobset covering doors 1-3/8 inch to 2-1/4 inch.
9) What comes in the box with the Emtek Modern Disc crystal knob set?
It ships as a complete set: both crystal disc knobs, the rosettes you select, the latch, and the strike plate. The latch faceplate is available with round or square corners, so match it to whatever mortise is already cut into your door edge. Nothing further is needed for a standard bored door beyond the screws in the kit.
10) What is the CF mechanism option on Emtek knob sets and should I pick it?
CF means concealed fastener: the rosettes mount with no exposed screws, which is the cleaner look most designers specify on a contemporary opening. Choosing CF on the Modern Disc set includes the 28 degree rotation latch. Your other two choices are the 28 degree latch on its own, or the standard latch. The 28 degree latch needs less knob rotation to retract, which is easier on small crystal knobs.
11) Can I match the Emtek crystal knob rosettes to the rest of my hardware?
Yes. The Modern Disc passage set is offered with #1, #2, #3, #4, and #6 rosettes, and it can be ordered with any Sandcast Bronze rosette. Finishes are Flat Black Bronze (FB), Medium Bronze (MB), and Tumbled White Bronze (TWB). A split finish can also be specified if you want a different finish inside versus outside the room.
12) I need a decorative passage knob but not glass. What else is there?
Several solid brass alternatives in the same decorative vein: the Omnia 434/PA is a traditional egg-shaped knob latchset in solid brass with a 3 inch projection, the Baldwin Estate 5011 Colonial passage knob comes with the 5058 rose, and the Baldwin Estate 5000 Baltimore knob is preconfigured as a passage lock with a 2-3/8 inch backset and full lip strike. The Emtek Modern Disc is the contemporary glass option; those three are the turned-metal look.
13) Can I use the Emtek Modern Disc passage set on a closet door that only needs a dummy knob?
You could, but it is the wrong function. A passage set includes a working latch and strike, which you do not want on a non-operating or ball-catch closet door. For a single dummy, pull-only application look at the BEST 6K single dummy trim, the Cal-Royal BA40 dummy knob, or the Omnia 434/0 egg-shaped single dummy in solid brass.
14) What is a lower-cost basic passage knob if the Emtek Modern Disc crystal knob is more than the job needs?
The Emtek Modern Disc passage set is a solid brass glass-style knob ordered with a choice of five rosettes and three bronze finishes. If the opening only needs a plain functioning passage knob, the Kwikset 200P Polo passage knob ships with a 6AL latch and RCS round corner strike, the Pamex FTF30 Baron is a Grade 3 passage knob lockset for doors 1-3/8 inch to 1-3/4 inch, and the Dexter C2000 passage ball knob is Grade 2 for the same door thickness range.
15) For a multi-family turn where I need several matching passage knobs at once, what is an alternative to ordering Emtek Modern Disc sets individually?
Emtek Modern Disc passage sets are ordered as complete single sets including latch and strike plate, with backset selected as 2-3/8 inch or 2-1/4 inch prep doors in mind. If the goal is standardizing many doors at once, 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.
16) What is the Emtek Modern Disc knob actually made of?
The lockset body and trim are brass, and the knob itself is from Emtek's Glass and Porcelain collection, so you get a crystal disc face on a brass mechanism. Brass substrate is what lets Emtek apply the living bronze finishes, Flat Black Bronze, Medium Bronze, and Tumbled White Bronze.
