Emtek 7208.CK.FB – Frequently Asked Questions
1) Will the Emtek Diamond crystal privacy knob fit my existing door prep?
If the door has the standard 2-1/8 inch cross bore, yes. The Emtek Diamond crystal privacy knobset drops into a 2-1/8 inch bore standard prep, and the latch is adjustable for either a 2-3/8 or 2-3/4 inch backset. One exception: 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 on a standard single-bore prep.
2) Which backset do I order for an Emtek crystal knob privacy set?
Backset is a required choice, 2-3/8 or 2-3/4 inches. Measure from the door edge to the center of the bore hole: residential interior doors are usually 2-3/8, and 2-3/4 shows up on heavier or commercial-prepped doors. The standard latch supplied is the 2-3/8 inch version, so 2-3/4 has to be specified.
3) Does the Emtek Diamond privacy knob come with a latch and strike, or do I buy those separately?
It ships as a complete set including the latch and strike plate, so nothing extra is needed to hang it on a prepped door. The latch faceplate can be had round corner or square corner to match the mortise already cut in the door edge.
4) What is the difference between the standard latch, the 28 degree latch, and the CF mechanism on this Emtek knobset?
Three latch choices. The standard latch is the conventional tubular latch. The 28 Degree Rotation Latch reduces how far the knob has to turn to retract the bolt, which suits crystal knobs where there is less grip surface. The CF Mechanism is the one to pick if you do not want screws showing on the rosettes, and it includes the 28 degree latch as part of the assembly.
5) Is this Emtek crystal knob a keyed lock or just a bathroom privacy lock?
Non-keyed. It is a privacy/bed/bath function tubular lockset, locked from the inside by thumbturn or button and released from outside in an emergency. For a keyed bedroom or office door you need an entrance function set instead, such as the Cal-Royal BER00 entrance/office knob lock.
6) My door is 2 inches thick. Will this Emtek crystal knob work?
No. The spec range for the Diamond crystal privacy knobset tops out at 1-3/4 inches. For a thicker slab, look at a set rated further, such as the Deltana 6112 St. Thomas privacy knob at 1-3/8 to 2 inches, or the Falcon X101 at 1-3/8 to 2-1/4 inches if a passage function works for the opening.
7) I need a plain privacy knob for a bathroom in a rental unit, not a crystal one. What should I use instead?
Utility privacy knobs with a stated ANSI grade include the Dexter C2000 Grade 2 privacy cylindrical ball knob, the Cal-Royal BER20 Grade 3 privacy knob with brass trim, and the Pamex FTF Grade 3 Baron privacy knob. All three are non-keyed Privacy/Bed/Bath function and fit doors 1-3/8 inch to 1-3/4 inch. The Emtek Diamond is a residential glass and porcelain collection knob in brass.
8) Can the Emtek Diamond privacy knobset be used on a commercial corridor or classroom door?
The Diamond crystal knobset is a residential privacy set with no keyway. For commercial openings the graded cylindrical locks are the fit: Sargent 8XG04 is a Grade 1 heavy duty storeroom knob lock with a 2-3/4 inch backset, Schlage D10S is a Grade 1 heavy duty passage knob lock, and the Dexter C2000 classroom ball knob is a Grade 2 keyed classroom function. Falcon X101 is a Grade 1 heavy duty passage knobset with a fire rating and a 1-3/8 to 2-1/4 inch door range.
9) What rosettes and finishes can I get with the Emtek Diamond crystal knob?
Rosette choices are #1, #2, #3, #4 and #6, and it 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 rosette in a different finish from the knob.
10) I need a decorative privacy knob but not glass. What else is there?
For a solid metal decorative privacy knob, the Baldwin Estate 5077 Bethpage with R027 rose and the Baldwin Estate 5000 Baltimore privacy set (2-3/8 inch backset, full lip strike) are both privacy function. The Deltana 6112 St. Thomas privacy knob is another option and is listed for 1-3/8 to 2 inch doors, which gives more thickness range than the Emtek Diamond's 1-3/8 to 1-3/4.
11) I ordered the Diamond privacy knob for the bedroom but the closet door does not need a lock. What matches it?
A privacy set locks; for a hall or closet door you want a passage or dummy function instead. Passage knobs in the same decorative residential family include the Baldwin Estate 5011 Colonial passage knob with 5058 rose and the Omnia 434/PA egg-shaped knob latchset in solid brass. For a door that does not latch at all, the Omnia 458/0 single dummy knob latchset or the Bravura Biloxi Grade 2 dummy knobset apply. The Emtek Diamond itself is Privacy/Bed/Bath only.
12) What should I use if the room needs a key rather than a privacy thumbturn?
The Diamond crystal knobset is non-keyed. For a keyed opening, the Cal-Royal BER00 is a Grade 3 entrance/office knob lock with a Kwikset keyway, the Kwikset 400P-CP is a Grade 3 keyed entry Polo knob for 1-3/8 to 1-3/4 inch doors with adjustable latch and round corner strike, and Deltana 3381 Egg Knob entry covers 1-3/8 to 2 inch in a decorative solid look.
13) I need to outfit a whole apartment building with matching interior knobs. Is the Emtek Diamond the right call?
The Diamond crystal set is a made-to-order residential decorative knob, chosen rosette by rosette and finish by finish across Flat Black Bronze, Medium Bronze and Tumbled White Bronze. For volume standardization, multi-packs and combo packs are the usual route: the Sure-Loc Bergen round knob ships 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 1-3/8 to 1-3/4 inch doors.
14) Can I match the Emtek Diamond crystal knobs across a whole floor of doors that need different functions?
The Diamond knob is part of Emtek's Glass and Porcelain collection in an American Classic styling, and rosette and finish choices are shared, so privacy sets on the bed and bath doors can be matched to the same knob and rosette on other openings. Keep the rosette number and finish code consistent across the order, and note that only the privacy function is non-keyed here.
