Emtek 7208.LW.FB – Frequently Asked Questions
1) Will an Emtek Lowell crystal privacy knob fit a 1-3/4 inch door?
Yes. The Lowell privacy knobset covers 1-3/8 inch through 2-1/4 inch doors on a standard 2-1/8 inch bore prep, so a 1-3/4 inch door (the usual commercial and solid-core thickness) is well inside the range. One exception on rosette choice: the STRETTO rosette needs a 1-1/4 inch diameter bore and a 2-hole door prep for the thumbturn, not the standard single 2-1/8 inch cross bore.
2) Do I need to specify a backset when ordering an Emtek Lowell privacy knob?
Yes, backset is a required choice. The Lowell privacy set ships with a 2-3/8 inch backset latch as standard; if the cross bore on your door is 2-3/4 inches from the door edge, you have to call that out on the order. Measure from the edge of the door to the center of the bore before you order. Those are the only two backsets offered.
3) Does the Emtek Lowell privacy knob set come with a latch and strike, or do I buy those separately?
It is a complete set. Latch and strike plate are both included, so nothing else is needed to hang it on a prepped door. The latch faceplate can be had round corner or square corner to match the existing mortise in the door edge, which matters on a retrofit where you do not want to re-chisel.
4) Is an Emtek crystal knob durable enough for an apartment building or a hotel corridor?
No, not for that traffic. The Lowell crystal knobset is a residential-rated tubular lockset in the Glass and Porcelain collection, built for interior bedroom and bath doors in a house or a high-end unit interior. For a commercial-duty opening you want a Grade 1 or Grade 2 cylindrical lock instead: the Schlage D Series D10S is Grade 1 heavy duty non-keyed, and the Corbin Russwin CK4410 is a Grade 2 cylindrical knob lock. Neither is a privacy function, so pick the privacy variant of that commercial series for a bath door.
5) My door is 2 inches thick. Which privacy knob will actually fit?
The Emtek Lowell privacy set is the one that reaches furthest here, covering 1-3/8 inch up to 2-1/4 inch. Most residential privacy knobs stop at 1-3/4 inch. If you want something other than the Emtek, the Deltana 6112 St. Thomas privacy knob is rated 1-3/8 to 2 inch, which just covers a 2 inch door. Anything listed only to 1-3/4 inch, such as the Pamex FTF Baron or Cal-Royal BER20 privacy knobs, will come up short on spindle and screw length.
6) Can I replace a standard builder-grade bathroom knob with an Emtek Lowell crystal knob without re-drilling the door?
In most cases yes. The Lowell privacy set drops into the same 2-1/8 inch cross bore that a standard residential knob prep uses, and the backset can be ordered to match either 2-3/8 or 2-3/4 inches. Pick the latch faceplate corner, round or square, to match the mortise already cut in the door edge and the swap is a straight one. The exception is the STRETTO rosette, which is not a standard-prep retrofit: it needs a 1-1/4 inch bore and a second hole for the thumbturn.
7) What is the closest equivalent to the Emtek Lowell privacy knob from another brand for a bedroom or bath door?
The Emtek Lowell knob in privacy function is a non-keyed bed and bath set built in brass. For a like-for-like function swap, the Deltana 6112 St. Thomas knob is a privacy/bed/bath knob that fits doors 1-3/8 inch to 2 inch thick, and the Baldwin Estate 5077 Bethpage privacy knob with R027 rose is also a privacy function knob. The Lowell differs in that it is a glass and porcelain collection knob offered on #1, #2, #3, #4 and #6 rosettes, while the Deltana and Baldwin sets are supplied with their own fixed rose designs.
8) Is there a simpler privacy knob to use instead of a crystal Emtek knob on back-of-house bedrooms?
Yes. The Pamex FTF Baron knob lockset in privacy function is a Grade 3 set for doors 1-3/8 inch to 1-3/4 inch, and the Cal-Royal BER20 is a Grade 3 privacy knob lock with brass trim for the same door thickness range. The Dexter C2000 privacy ball knob is a Grade 2 non-keyed privacy set for 1-3/8 inch to 1-3/4 inch doors. All three are plain metal knobs; the Emtek Lowell is a glass knob in the Glass and Porcelain collection with a choice of Flat Black Bronze, Medium Bronze or Tumbled White Bronze finish.
9) The door I am working on is thicker than 1-3/4 inch. What privacy or passage knob covers that?
The Emtek Lowell privacy set is specified for doors 1-3/8 inch to 1-3/4 inch. Where the leaf runs thicker, the Deltana 6112 St. Thomas privacy knob covers 1-3/8 inch to 2 inch, and on the passage side the Corbin Russwin CK4310 Grade 1 non-keyed passage knob covers 1-3/8 inch to 2 inch and the Falcon X101 Grade 1 heavy duty passage knobset covers 1-3/8 inch to 2-1/4 inch. The Deltana keeps the residential privacy function; the Corbin Russwin and Falcon are passage sets with no locking.
10) What should I specify instead if the opening is a commercial door that needs an ANSI grade?
The Emtek Lowell is a residential knobset. Where a graded cylindrical lock is required, the Schlage D10S is a Grade 1 heavy duty non-keyed passage knob lock, the Sargent 8XG04 is a Grade 1 heavy duty storeroom knob lock with a 2-3/4 inch backset, and the Falcon W101 is a Grade 2 medium duty passage knob lock with a 2-3/4 inch backset and a fire rating. Note these are passage and storeroom functions rather than the bed and bath privacy function the Lowell performs.
11) Which knobs look like a substitute for the Lowell privacy set but will not lock the door?
Several similar-looking knobs are dummy or passage trim and have no thumbturn. The BEST 6K single dummy trim, Bravura Biloxi dummy knobset, Schlage A170 single dummy trim, Omnia 434/0 and Omnia 458/0 are all dummy function, meaning fixed trim with no latch operation. The Kwikset 200P Polo, Bravura Albany and Bravura Lynchburg are passage sets, which retract a latch but do not lock. The Emtek Lowell is a privacy/bed/bath set, which is the function that gives you a bedroom or bathroom lock.
12) What is the CF mechanism option on Emtek knobs and should I pick it?
CF stands for the concealed-fastener build: the rosettes mount with no exposed screws, so you get a clean rose face on both sides of the door. It is the option to take on a visible-finish job where the buyer is paying for the crystal knob and does not want screw heads in the rose. Choosing CF also brings the 28 degree rotation latch with it. The alternatives are the standard latch or the 28 degree rotation latch on its own.
13) What finishes and rosette shapes does the Emtek Lowell privacy knob come in?
Three finishes: Flat Black Bronze (FB), Medium Bronze (MB), and Tumbled White Bronze (TWB). Five rosette designs are offered, #1 through #4 plus #6, and the knob can be ordered with any Sandcast Bronze rosette, so the rose shape can be matched to whatever else is already on the floor. If two openings need different finishes on either face, there is a split-finish option to specify at order time.
14) What else could I use instead of an Emtek crystal privacy knob for a bathroom door?
Depends what you are optimizing for. If you want the same decorative, solid-brass residential look, the Baldwin Estate 5077 Bethpage privacy knob with the R027 rose and the Deltana 6112 St. Thomas privacy knob (1-3/8 to 2 inch doors) are both privacy-function decorative knobs. If the job is a rental turn or a spec-builder run where cost and speed matter more than the crystal, the Pamex FTF Baron Grade 3 privacy knob and the Cal-Royal BER20 Grade 3 privacy knob both cover 1-3/8 to 1-3/4 inch doors. The Dexter C2000 privacy knob is the Grade 2 step up in that same plain-knob category.
15) I need a keyed knob for an entry or office door in the same job. What do I order alongside the Lowell privacy knobs?
The Emtek Lowell privacy knob is non-keyed, so it will not take a cylinder. For keyed openings on the same job, the Cal-Royal BER00 is a Grade 3 entrance/office knob lock with a Kwikset keyway for 1-3/8 inch to 1-3/4 inch doors, the Pamex FTF Baron entrance/office set is Grade 3 for the same door range, and the Dexter C2000 entry/office ball knob is a Grade 2 keyed set for 1-3/8 inch to 1-3/4 inch doors. For a heavier commercial entry, the BEST 8K single cylinder entrance knob lock is Grade 1 heavy duty.
16) What is the difference between the Emtek Lowell privacy knob and the Baldwin Estate 5000 Baltimore privacy knob?
Both are privacy function knobs. The Baldwin Estate 5000 Baltimore privacy set is preconfigured with a 2 inch knob, 5148 rose, 2-3/8 inch backset and a full lip strike. The Emtek Lowell is a glass knob ordered with a choice of rosette and a backset selection of 2-3/8 inch or 2-3/4 inch, and it can be built with a standard latch, a 28 degree rotation latch, or the CF mechanism with no exposed rosette screws.
17) Can I match the Emtek Lowell privacy knob with a passage knob for the hall and closet doors?
The Lowell privacy set is a bed and bath function only. If you are pairing across a house, the Baldwin Estate 5011 Colonial passage knob with 5058 rose and the Baldwin Estate 5000 Baltimore passage knob with 5048 rose and 2-3/8 inch backset are passage function knobs, and the Omnia 434/PA egg-shaped knob latchset is a solid brass passage set with a 3 inch projection. The Lowell itself is brass with a glass knob, so the finish family and material of the pairing set is worth confirming against the Flat Black Bronze, Medium Bronze or Tumbled White Bronze you select.
18) Is there a knob option that locks without a key or a thumbturn for a shared unit door?
The Lockey 3830 is a mechanical keyless combination knob lock with an auto-locking passage function, for doors 1 3/16 inch to 2 inch thick. That is a code-entry approach rather than the thumbturn privacy locking the Emtek Lowell provides, and the Lowell is a non-electronic mechanical set in the tubular lock family.
19) We standardize on Grade 2 cylindrical knobs across our buildings. Which knobs meet that where the Emtek Lowell would not?
For a Grade 2 standard across a facility, the Arrow MK01 and Arrow RK01 are Grade 2 non-keyed passage cylindrical knob locks for 1-3/8 inch to 1-3/4 inch doors, the Corbin Russwin CK4410 is a Grade 2 non-keyed passage knob for the same door range, the Sargent 6G04 is a Grade 2 storeroom knob lock with a single cylinder, and the Dexter C2000 privacy ball knob is the Grade 2 option that keeps the bed and bath function the Emtek Lowell performs.
20) What is a 28 degree rotation latch and why would I want one on a knob?
A 28 degree latch retracts with less knob rotation than a standard tubular latch, so the knob turns a shorter arc to pull the bolt. On the Lowell crystal knob it is offered as its own latch choice and it also comes bundled with the CF concealed-fastener mechanism. If you are matching the feel of other Emtek openings already installed, pick the same latch type across the doors.
21) Should I use a knob or a lever for interior bedroom and bath doors?
A knob like the Emtek Lowell crystal is a residential choice, and it is what most houses and high-end unit interiors use for bedrooms and baths. Where the opening has to be operable without grasping and twisting, or the facility follows accessible-design requirements, a lever is the operator to specify instead. Emtek publishes the knobset and leverset dimension and door-thickness data together, so the same rosettes and prep logic carry across if you switch to a lever.
22) What is the Emtek Lowell knob made of?
Brass, both the substrate and the body material, with a crystal knob from the Glass and Porcelain collection. The three finishes offered, Flat Black Bronze, Medium Bronze, and Tumbled White Bronze, are all Sandcast Bronze rosette finishes, which is why the rose has the hand-cast texture rather than a plated smooth face.
23) If I want one box that covers both the entry and the interior doors, is there an alternative to ordering the Emtek Lowell set by set?
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. The Emtek Lowell is sold as a complete set including latch and strike plate, built to the backset, rosette, latch type and finish you specify.
