Emtek 8200.LN.US15 – Frequently Asked Questions
1) Will the Emtek Lancaster privacy knob fit a standard pre-drilled door with a 2-1/8 inch bore?
Yes. The Lancaster privacy knobset is a tubular lockset built for standard door prep, meaning a 2-1/8 inch cross bore with the edge bore below it. No special routing is needed for the common rosettes. The one exception is the STRETTO rosette, which needs a 1-1/4 inch diameter bore and a 2-hole door preparation for the thumbturn privacy mechanism, so if you are matching a STRETTO rose you are drilling a different pattern than the rest of the range.
2) Do I need to order the Emtek Lancaster privacy knob for a 2-3/8 or 2-3/4 inch backset?
Backset is a required choice at order, either 2-3/8 or 2-3/4 inches. Measure from the door edge to the center of the bore hole: 2-3/8 is the usual residential interior backset and 2-3/4 shows up more on wider stiles and some commercial-style preps. The standard latch supplied is the 2-3/8 inch version, so you have to call out 2-3/4 if that is what your door is bored for.
3) Is an Emtek Lancaster knob suitable for a commercial building or a school corridor?
No. Emtek's Lancaster brass knobset is a residential decorative lockset, not a graded commercial cylindrical lock. For a commercial opening where you need an ANSI grade behind it, look at a Grade 1 or Grade 2 cylindrical knob such as the Schlage D Series D10S passage, the Corbin Russwin CK4310 Grade 1, or the Dexter C2000 Grade 2 privacy knob.
4) What is the closest decorative brass privacy knob alternative to the Emtek Lancaster privacy knobset?
The Baldwin Estate 5077 Bethpage privacy knob with R027 rose is the closest decorative equivalent - it is a privacy/bed/bath knob like the Lancaster, and comes as a knob and rose combination rather than a knob-and-rosette build-up. The Emtek Lancaster privacy set is solid brass and can be ordered with any brass rosette, including Lancaster, Oval, Quincy, Rectangular, Ribbon & Reed, Rope, Watford and Wilshire, so if the design intent is to match a specific rose profile across the house, the Emtek gives the wider rose choice while the Baldwin 5077 is a fixed knob and rose pairing.
5) I need a privacy knob for a rental bathroom door and do not need decorative brass. What else works?
For a straightforward bed and bath door, the Cal-Royal BER20 is a Grade 3 privacy knob lock with brass trim that fits doors 1-3/8 inch to 1-3/4 inch, and the Pamex FTF Baron is a Grade 3 privacy knob lockset for the same door thickness range. If the door sees heavier turnover, the Dexter C2000 Series privacy cylindrical ball knob is a Grade 2 non-keyed privacy lock, also for 1-3/8 inch to 1-3/4 inch doors. The Emtek Lancaster privacy set is a residential solid brass set whose appeal is the knob and rosette design mix; these three are utility privacy knobs with a single fixed trim.
6) Can I use the Emtek Lancaster privacy knobset on a commercial corridor or office door?
The Lancaster privacy knobset is a residential tubular non-keyed set, so it is not the right choice for a commercial opening that needs a graded cylindrical lock. For those doors the Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet knob lock with a 2-3/4 inch backset, the Schlage D10S is a Grade 1 heavy duty passage knob lock, and the Corbin Russwin CK4851 is an entrance/office cylindrical knob lock with a conventional cylinder for doors 1-3/8 inch to 2 inch. Those are keyed or graded commercial functions; the Lancaster is a bed and bath privacy set.
7) My door is 2 inches thick. Will the Emtek Lancaster privacy knobset fit, or do I need something else?
The Lancaster privacy knobset is specified for doors 1-3/8 inch to 1-3/4 inch with a 2-1/8 inch cross bore. For a 2 inch door, the Deltana 6112 St. Thomas privacy knob covers 1-3/8 inch to 2 inch and is also a privacy/bed/bath function, which makes it the direct swap on a thicker slab. On the commercial side, the Falcon X101 passage knobset covers 1-3/8 inch to 2-1/4 inch, though that one is a passage function rather than privacy.
8) What is the CF mechanism option on Emtek knobsets and should I pick it?
CF stands for concealed fastener. Choose it and the rosettes mount with no exposed screws on the face of the rose, which is what most designers want on a visible interior door. The CF option includes the 28 degree rotation latch. If you do not care about seeing screw heads, the standard latch or the standalone 28 degree latch will work on the same door prep.
9) Can I mix Emtek Lancaster knobs with a different rose shape to match the rest of my doors?
Yes. The Lancaster knob can be ordered on any brass rosette in the range, so you can run the Lancaster rose on one door and an Oval, Rectangular, Quincy, Regular, Ribbon and Reed, Rope, Watford, Wilshire or #8 rose elsewhere and keep the same knob shape throughout the house. That is how most property owners standardize an older home where trim styles differ room to room.
10) Is the Emtek Lancaster privacy knob keyed, and how does the lock release in an emergency?
It is a non-keyed privacy function for bedrooms and bathrooms. There is no cylinder and no key. It locks from the inside and has the usual emergency release on the outside face, so it is not a security lock and should not be used on an exterior or entry door. For a keyed opening you need an entry or keyed-entry set instead.
11) What is a comparable solid brass privacy knob if the Emtek Lancaster does not suit?
Two close decorative equivalents are the Baldwin Estate 5077 Bethpage privacy knob with the R027 rose and the Deltana 6112 St. Thomas privacy knob, which is listed for doors 1-3/8 to 2 inches thick. If you want a plainer budget privacy knob for a rental turn rather than a designer finish, 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.
12) My interior doors are thicker than standard - can I still use the Emtek Lancaster privacy set?
Door thickness is a field you fill in when ordering the Lancaster privacy set, so tell us the actual measured thickness of the door and the set is supplied to suit. Measure the door itself, not the casing, at the lock stile.
13) Is the Baldwin 5000 Baltimore privacy knob interchangeable with the Emtek Lancaster privacy set?
Both are privacy knobsets, but they are ordered differently. The Baldwin Estate 5000 Baltimore knob with 5148 rose is preconfigured with a 2-3/8 inch backset and full lip strike, so it ships as one fixed configuration. The Emtek Lancaster privacy set is ordered with a backset selection of 2-3/8 inch or 2-3/4 inch, a choice of ten brass rosettes, and a latch choice of standard, 28 degree rotation, or the CF mechanism that leaves no exposed screws on the rosettes. If the existing prep is 2-3/4 inch backset, the Lancaster can be specified for it directly.
14) What if I want the same Emtek look on a closet or hall door that should not lock?
Privacy is the wrong function for a closet or hall door since it adds a thumbturn and emergency release. For non-locking openings, the Baldwin Estate 5011 Colonial passage knob with 5058 rose and the Omnia 434/PA egg-shaped knob latchset in solid brass keep the traditional brass look, and the Baldwin Estate 5000 Baltimore knob with 5048 rose comes preconfigured as a passage lock with a 2-3/8 inch backset and full lip strike. For a door leaf that needs a knob but no latch at all, the Omnia 458/0 and Omnia 442/00 are single dummy brass knob latchsets.
15) I need to key the bedroom door. Does the Emtek Lancaster privacy set do that?
No - the Lancaster privacy set is a non-keyed bed and bath function with no cylinder. For a keyed knob on that opening, the Cal-Royal BER00 is a Grade 3 entrance/office knob lock with a Kwikset keyway for doors 1-3/8 inch to 1-3/4 inch, the Kwikset 400P-CP Polo is a Grade 3 keyed entry knob with a round corner adjustable latch and strike for the same thickness range, and the Pamex FTF Baron is available in a Grade 3 entrance/office function. In brass decorative styling, the Deltana 6901 Portland and Deltana 6171 Round knob are entry-function knobs.
16) Which knobsets look like substitutes for the Emtek Lancaster privacy set but will not actually lock a bathroom door?
Watch the function line. The BEST 6K Series single dummy trim, the Bravura Biloxi dummy knobset, the Cal-Royal BA40 dummy knob, and the Schlage A170 single dummy trim are all knobs with no latch mechanism at all - they mount to a door face and do nothing. The Sargent 78-2875 outside knob and the Imperial USA ED-BKL580 knob trim are exit device trim, not a standalone bored lockset. The Emtek Lancaster privacy set is a complete tubular privacy set sold with latch and strike plate.
17) For a multi-family turn where I need matching knobs on several bedroom and bath doors, what are the alternatives to the Emtek Lancaster privacy set?
The Lancaster privacy set is ordered one configuration at a time with your choice of backset, rosette, latch and finish, which suits a matched design package. If you want volume consistency instead, 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 doors 1-3/8 inch to 1-3/4 inch, so a single order covers several openings.
18) What is the difference between the Emtek Lancaster privacy knobset and a Grade 2 cylindrical privacy knob like the Dexter C2000?
The Dexter C2000 Series privacy knob is a Grade 2 non-clutching cylindrical ball knob lock for doors 1-3/8 inch to 1-3/4 inch - a utility lock with a fixed ball knob and one trim. The Emtek Lancaster privacy set is a residential solid brass tubular set built from a Lancaster knob plus your choice of brass rosette, offered in French Antique, Oil Rubbed Bronze, Pewter, Polished Brass, Polished Chrome, Satin Nickel and Unlacquered Brass. Both cover the same bed and bath duty; the difference is graded cylindrical hardware versus a decorative brass build.
19) What finishes does the Emtek Lancaster knob come in, and can I get two different finishes on one door?
Seven brass finishes: French Antique (US7), Oil Rubbed Bronze (US10B), Pewter (US15A), Lifetime Polished Brass (US3), Polished Chrome (US26), Satin Nickel (US15), and Unlacquered Brass (US3NL). Split finish is available as an order option, so you can run one finish on the hall side and another on the room side where the two rooms are decorated differently. Note the unlacquered brass will patina over time by design, while the lifetime polished brass will not.
