Emtek 5109US19.CCUS19.TZKLT – Frequently Asked Questions

1) Will the Emtek Terrazzo passage knob fit a 1-3/4 inch door with a standard 2-1/8 inch bore?
Yes. The Conical Terrazzo knob passage set drops into a standard door prep with a 2-1/8 inch cross bore, and it covers doors from 1-3/8 up to 2-1/4 inches thick. One catch: if you pick the Concealed Fastener (CF) mechanism, the range narrows to 1-3/8 to 1-3/4 inches, so a thicker door needs the standard latch or a thickness noted on the order.
2) What backset do I need to specify on the Emtek Terrazzo knob passage set?
Backset is a required choice, 2-3/8 or 2-3/4 inches. The standard latch ships 2-3/8 inch unless you call out 2-3/4. Measure from the door edge to the center of the bore hole on the existing prep and match it. Both are common in the field, so guessing gets you a latch that will not reach the strike.
3) Does the Emtek Terrazzo passage knob lock, or is it just a handle?
It does not lock. Passage function means the knob turns the latch from either side at all times, non-keyed, with no privacy button or thumbturn. That is the right pick for a hall, closet, pantry, or a bedroom door where nobody needs to lock it. If you want the bathroom or bedroom to lock, you want the privacy version of the same knob, not this one.
4) What is the Concealed Fastener (CF) mechanism on Emtek knobs and should I order it?
CF hides the mounting screws so the rosette face is clean with no visible fasteners. The trade-off is door thickness: CF handles 1-3/8 to 1-3/4 inches, while the standard latch mechanism goes up to 2-1/4 inches. CF also brings the 28 degree latch with it. If the door is standard thickness and the look matters, take CF. On a thick door, take the standard latch.
5) Is the Emtek Terrazzo knob suitable for a commercial building or apartment corridor?
No. This is residential brass decorative hardware, a knob on a tubular latch, not a commercial cylindrical lockset. For a corridor, office, or leased space that needs a graded lock, look at a Grade 1 cylindrical passage lever like the Falcon K101, which covers 1-3/8 to 2-1/4 inch doors and is fire rated, or the Corbin Russwin CL3110 for 1-3/4 to 2 inch doors. Both are levers rather than knobs, which is what most commercial specs call for anyway.
6) What is a commercial-grade alternative to the Emtek Terrazzo conical knob passage set for a high-traffic corridor door?
The Emtek Terrazzo conical knob passage set is a residential passage set with a brass handle and tubular lock chassis. For a corridor opening that needs a commercial-duty passage function instead, the Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers, fire rated, covering 1-3/8 inch to 2-1/4 inch doors. The Falcon T101 is another Grade 1 heavy duty passage lever. Both are lever trim rather than a knob, which is the trade-off if the design intent was a knob.
7) What decorative passage set is the closest equivalent to the Emtek Conical Terrazzo knob?
The Baldwin Estate 5103 Passage Lever with 5048 Rose is the nearest decorative-brand peer, a passage function set in the same residential decorative category. The difference is handle form: the Emtek Terrazzo set is a knob on a conical stem with a choice of rosettes including Disk, Square, Quincy, Watford and Wilshire, while the Baldwin 5103 is a lever fixed to the 5048 rose.
8) I need a bedroom or bathroom lock, not a passage set - what takes the place of the Emtek Terrazzo conical knob?
The Emtek Terrazzo conical knob set is a non-keyed passage function, so it has no locking mechanism and is wrong for a bedroom or bath. For a privacy function instead, the Baldwin Estate 5103 Privacy Lever with 5048 Rose is a decorative privacy set, the Kwikset 300BRNL RDT Breton is a Grade 3 privacy lever for 1-3/8 inch to 1-3/4 inch doors, and the Hager 2540 is a Grade 2 privacy cylindrical lock with Withnell lever for 1-3/8 to 2 inch doors.
9) Which rosette shapes can I get with the Emtek Conical Terrazzo knob?
Seven rosettes: Disk, Modern Rectangular, Quincy, Square, Urban Modern, Watford, and Wilshire. The knob works with any brass rosette in the line, so the rosette is what sets the visual style, round for traditional openings, Square or Modern Rectangular for a contemporary look. The Terrazzo knob itself is offered in the Light Terrazzo handle on a Conical brass stem.
10) Can I match the Terrazzo knob to the other Emtek hardware already in the house?
Seven finishes are offered on the rosette and stem: Flat Black (US19), Oil Rubbed Bronze (US10B), Polished Chrome (US26), Polished Nickel Lifetime (US14), Satin Brass (US4), Satin Nickel (US15), and Unlacquered Brass (US3NL). The rosette shape is a separate choice, so you can carry the same rosette and finish across every opening and change only the function from door to door.
11) I need a decorative brass passage set but a lever instead of a knob. What else is there?
Knobs are harder for anyone carrying a load or with limited grip, and some jurisdictions want levers on accessible openings. In decorative brass, the Baldwin Estate 5103 passage lever with the 5048 rose is the closest equivalent in look and function. For a lighter-duty residential lever, the Bravura Miramar passage leverset in US4 Satin Brass matches a brass finish scheme at Grade 2.
12) Can I use the Emtek Terrazzo passage knob on a French door or as a pull only?
Not on a door that needs no latch. This set is a working passage knob with a latch and strike, so it needs a bored door with a latch mortise in the edge. For an inactive leaf or a false door where you only want the handle on the surface, you need a dummy set instead. Baldwin's Estate 5103 comes in left and right hand half dummy versions if you want a decorative match on the fixed leaf.
13) Is the Emtek Conical Terrazzo knob handed? Do I need to specify left or right?
No handing to specify. Passage function knobs turn from both sides and the set installs the same either way, so there is no left hand or right hand version. What you do have to get right on the order is the backset, 2-3/8 or 2-3/4 inches, and the door thickness if it is over 1-3/4 inches.
14) The door is a closet with no working latch needed - is there a dummy version instead of the Emtek Terrazzo passage set?
The Emtek Terrazzo conical knob passage set ships as a complete set with a latch and strike plate, so it operates a latch. Where the door needs only surface-mounted trim with no latch, dummy sets in the comparable range include the Baldwin Estate 5103 half dummy lever with 5048 rose in both left hand and right hand versions, the Callan Bentley Grade 2 dummy lever, and the BEST 7KC single dummy trim, a Grade 2 medium duty non-keyed lever.
15) Which passage sets look like substitutes for the Emtek Conical Terrazzo knob but will not match it on the other doors?
Several passage sets share the function but not the trim. The Accentra 5301LN Augusta and 4601LN are Grade 2 cylindrical passage lever locks, the Design Hardware J75 and X75 are flat lever passage locksets for 1-3/4 inch doors, and the Bravura Miramar, Atlanta, Orlando and Tampa are Grade 2 passage leversets on round or square trim. All of them are commercial-style lever trim, whereas the Emtek Terrazzo set is a knob on a conical stem in a contemporary decorative style, so they will not read as the same hardware on adjacent openings.
16) Which lock handles a storeroom or utility door where the Emtek Terrazzo conical knob passage set will not?
A passage set latches but never locks, so it is not suited to a storeroom. The Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors, the Hager 2580 is a Grade 2 storeroom cylindrical lock with Withnell lever for 1-3/8 inch to 2 inch doors, and for utility and institutional openings the Dexter C1000 asylum function is a Grade 1 lock covering 1-3/8 inch to 2 inch.
17) What is a simpler passage set than the Emtek Conical Terrazzo knob for a rental turn?
The Emtek Terrazzo conical knob set is a brass SELECT Series build ordered by rosette, stem finish and backset. Where a straightforward stocked passage set is enough, the Kwikset 200BRNL RDT Breton is a Grade 3 passage lever for 1-3/8 inch to 1-3/4 inch doors, the Kwikset 200DL Delta is a reversible passage lock with an adjustable 6AL latch and RCS strike, and the Callan Asheville is a Grade 3 passage leverset in satin nickel.
18) We need keyless code entry on this door - what goes in instead of the Emtek Terrazzo conical knob passage set?
The Emtek Terrazzo conical knob set is a non-electronic, non-keyed passage set with no code or credential capability. For code entry on the same door, the Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function and ADA compliance for 1 3/16 inch to 2 inch doors, the Lockey 1150 is a heavy duty mechanical keypad lever set with double combination and passage function for 1-1/8 inch to 2 inch doors, and the Delaney LP250 is a Grade 2 electronic keypad leverlock.
19) What is the Emtek Terrazzo knob actually made of?
Brass throughout the rosette and stem, with a Light Terrazzo handle on a Conical brass stem. Brass is a solid substrate that takes plated and living finishes, which is why the range runs from Flat Black through to Unlacquered Brass that will patina over time rather than hold a coating.
20) Which classroom-function lock would pair with the Emtek Terrazzo passage sets used elsewhere in the building?
The Emtek Terrazzo conical knob set is a non-keyed passage set, correct for corridor and closet doors but not for a classroom. The Dexter C1000 classroom lock is a Grade 1 clutching keyed lever for 1-3/8 inch to 1-3/4 inch doors, the Dexter C1000 classroom security version adds keyed control from both sides in the same Grade 1 range, and the Cal-Royal AG03 classroom lever is Grade 2 with a 6-pin Schlage C keyway keyed different on a 2-3/4 inch backset, which matches the wider backset option on the Terrazzo set.
