Emtek F20-3543-75-RH-US26 – Frequently Asked Questions
1) Do I have to specify handing when ordering an Emtek 3543 Charleston mortise entry set?
Handing is required on every Emtek mortise lock, including the 3543 Charleston. You pick from LH, RH, LHR or RHR, and the two reverse options (LHR and RHR) are the out-swing doors. Stand outside the door: if it swings toward you it is a reverse hand. Get this wrong and the latch bevel faces the wrong way, so nail it down before the order goes in.
2) Will the Emtek 3543 Charleston mortise lock fit my existing door prep?
The 3543 Charleston uses the standard mortise pocket prep to ANSI A115.1, so it drops into a door already mortised for a standard mortise lock body. Backset is either 2-1/2 inch or 2-3/4 inch, so match whichever your existing prep uses. Door thickness is 1-3/4 inch as standard, and a thicker door has to be called out on the order.
3) What is the difference between the F20 and F13 function on the Emtek Charleston mortise lockset?
Two functions are offered on the 3543. F20 is the entrance function, the normal front-door choice: key outside, thumbturn or button control inside. F13 is the dormitory function, used where the door needs to stay locked outside and free egress inside on a bedroom or unit door. Both are UL listed mortise functions, and you choose one at order time.
4) Can I key the Emtek Charleston mortise lockset to match my other Schlage keyed locks?
The 3543 uses a Schlage C keyway, so it keys into an existing Schlage C system. It is a single cylinder keyed entry set, and you can order it keyed different or keyed alike across multiple sets, or keyed to a specific code if you have a bitting list for the building.
5) Which backset do I order on an Emtek mortise entry set, 2-1/2 or 2-3/4 inch?
Measure from the door edge to the center of the knob or lever spindle hole on the existing prep. That number is your backset, and the 3543 is made in both 2-1/2 inch and 2-3/4 inch. On a new door being machined, either works, so pick the one that puts the knob a comfortable distance off the edge for the door width you have.
6) What is the closest equivalent to the Emtek 3543 Charleston mortise entrance lockset from another brand?
The Baldwin 6301 mortise lock body is the nearest match in the same decorative residential vein: it is an entrance/apartment function mortise lock body on a 2-1/2 inch backset, and it comes in both a knob by knob version (6301) and a lever by lever version (6301LS). The Emtek 3543 Charleston is an entry function mortise set in solid brass, offered on 2-1/2 inch and 2-3/4 inch backsets, with the inside trim chosen from a knob, crystal knob, or lever. If your opening is prepped for a 2-1/2 inch backset, the two land in the same place functionally; the Emtek adds the 2-3/4 inch backset option and the choice of a dormitory function alongside the entrance function.
7) Is the Emtek 3543 Charleston mortise lockset rated for a commercial entrance, or should I specify a Grade 1 lock instead?
The Emtek 3543 Charleston is classified as residential and is built around decorative brass trim with a UL listed mortise body in F20 entrance or F13 dormitory function. For an opening where the spec calls out ANSI/BHMA Grade 1, choose a lock the set carries that grade on: the Cal-Royal NM8050 is a Grade 1 heavy duty office/entrance mortise lockset with an auxiliary deadlatch, and the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever. Those are the ones to put on a drawing that names a grade; the Charleston is the one to put on a residential or light-traffic entry where the finish and trim style are the deciding factor.
8) My door is thicker than 1-3/4 inches. Does the Emtek 3543 Charleston still work, or do I need a different lock?
The Emtek 3543 Charleston is built for a 1-3/4 inch door as standard and can be ordered for a thicker door if you specify the thickness. Among mortise locks that state a range above 1-3/4 inches, the Baldwin 6301 lock body covers 1-3/4 inch and over, and the Hager 3810E and 3810S 3800 Series passage mortise locks cover 1-3/4 inch to 2-1/2 inch on a 2-3/4 inch backset. The Hager pair are passage function, so they are the answer only where the door does not need to lock; for a keyed thick door in the Charleston style, order the Emtek and state the door thickness with the order.
9) I need a fire rated mortise lock for a labeled opening - how does the Emtek 3543 Charleston compare?
The Emtek 3543 Charleston is a UL listed mortise lock with a UL 180 minute fire rating, on a standard mortise door prep to ANSI A115.1. If the opening calls for a longer rating, the Schlage Electronics LEMD-GRW ENGAGE Series wireless mortise lock carries a 3 hour fire rating at Grade 1, and the Schlage Electronics LEBMB-ADD mobile enabled mortise lock also carries 3 hours at Grade 2. Those two are credential-based locks rather than keyed decorative sets, so match the rating your label requires first, then the way the door is meant to be operated.
10) What knobs and levers can I put on the inside of an Emtek Charleston mortise entry set?
The interior trim is your pick from the full Emtek brass, crystal and porcelain range, roughly ninety styles, from plain levers like the Stuttgart, Athena and Milano to knobs like the Egg, Providence and Square, crystal knobs such as the Windsor and Georgetown, and the knurled and marble options in the L-Square, T-Bar and R-Bar families. That is a required selection when you order, so decide the inside look before you buy.
11) I want a decorative mortise entry lock but my door is thicker than 1-3/4 inch. What are my options?
The 3543 Charleston is built for 1-3/4 inch as standard and a thicker door has to be called out when ordering, so it can be supplied that way. If you would rather have a lock body already rated across a thickness range, the Baldwin 6301 entry/apartment mortise body at 2-1/2 inch backset covers 1-3/4 inch and over, and the Hager 3810E Grade 1 covers 1-3/4 to 2-1/2 inch with escutcheon trim at a 2-3/4 inch backset.
12) Can I use the Emtek Charleston mortise set to replace a Baldwin mortise entry lock?
Both work off the same standard mortise pocket, and the 3543 is prepped to ANSI A115.1 at a 2-1/2 or 2-3/4 inch backset. The Baldwin 6301 entry/apartment body is a 2-1/2 inch backset lock, so a door already carrying one has the pocket and backset the Emtek 2-1/2 inch version needs. What will not carry over is the trim footprint and the cylinder: the Emtek runs a Schlage C keyway, so existing Baldwin keys will not work it.
13) I need a keyless entry on the same mortise door prep - what replaces the Emtek 3543?
The Emtek 3543 Charleston is a keyed mechanical lock with a single cylinder on a Schlage C keyway, so it has no code or credential entry. For keyless on a mortise prep, the set carries several: the Alarm Lock DL2700CR Trilogy T2 is an electronic mortise lock with classroom function and a weatherproof design, the Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock, and the Schlage CO-100 is a standalone electronic mortise lock with a keypad reader in privacy function. Pick by the function you need behind the credential, since those three are classroom, keyless pushbutton, and privacy respectively - none of them is an entrance function equivalent to the Charleston.
14) What is the difference between the Emtek 3543 Charleston entrance set and a mortise deadbolt like the Sargent 4874?
The Emtek 3543 Charleston is a complete entrance set - the mortise lock body, latch, strike plate and trim, with a single cylinder and a latch that retracts by the knob or lever. The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset, and the Kaba Ilco 185 Series is likewise a deadbolt function mortise lock. A deadbolt throws a bolt and has no latch or handle operation, so it is an addition to a door that already has a knob or lever set, not a replacement for the Charleston. If you want a second cylinder on the Charleston opening itself, note that the 3543 is single cylinder.
15) I ordered the Emtek 3543 in dormitory function. What else gives me a dormitory or corridor lock on a mortise prep?
The Emtek 3543 Charleston is available in F13 dormitory function as well as F20 entrance. The Sargent 7925 is the peer to look at: a dormitory exit function mortise lock with rose trim and a single cylinder deadbolt, Grade 1 heavy duty, in the 7900 Series with a corridor/dormitory function. The Sargent adds a deadbolt within the lock body and comes on rose trim; the Emtek in F13 is a brass decorative set where the inside trim is chosen from the knob, crystal knob and lever range.
16) Can I use the Emtek 3543 Charleston on a classroom or storeroom door?
The Emtek 3543 Charleston is an entry function set, offered as F20 entrance or F13 dormitory, so it is not a classroom or storeroom lock. For classroom, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for a 1-3/4 inch door, and the Cal-Royal NM8070 is a Grade 1 heavy duty classroom mortise lockset with an auxiliary deadlatch. For storeroom, the Cal-Royal NM8080 is a Grade 1 heavy duty storeroom mortise lockset with an interchangeable core option. Those functions control the outside lever independently of the inside, which the entrance and dormitory functions on the Charleston do not do.
17) Does the Emtek 3543 Charleston need handing, and is there a mortise lock that does not?
Handing is required on the Emtek 3543 Charleston - you specify LH, RH, LHR or RHR, with the reverse hands used for an out-swing door. If you would rather not commit to a hand at the time of order, several mortise locks in the set are field reversible or handless: the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation, the BEST 45H Series public entrance mortise lock body is also field reversible, and the Kaba Ilco 185 Series mortise locks require no handing. Those are passage, public entrance and deadbolt functions respectively, so reversibility comes with a different function than the Charleston entry set.
18) Is the Baldwin 6310 a substitute for the Emtek 3543 Charleston entry set?
They are close in family but not the same function. The Baldwin 6310 is an entrance/storeroom mortise lock body on a 2-1/2 inch backset for doors 1-3/8 inch and over, offered knob by knob and as the 6310190RRLS right hand reverse lever by lever version. The Emtek 3543 Charleston is an entry function set - F20 entrance or F13 dormitory - and ships complete with the latch and strike plate, with the inside knob or lever selected separately. A storeroom function keeps the outside trim locked at all times, which is a different behavior from an entrance function, so confirm which one the door is meant to do before swapping.
19) Which mortise entry lock should I standardize on across a multi-family building - the Emtek 3543 Charleston or something else?
The Emtek 3543 Charleston is a residential brass set, keyed on a Schlage C keyway with free keyed alike or keyed different setup at the time of order, in eight finishes from Flat Black US19 to Unlacquered Brass US3NL - so a whole building can be brought onto one key and one finish. Where the units need a graded commercial lock instead, the Cal-Royal NM8050 is a Grade 1 heavy duty office/entrance mortise lockset with auxiliary deadlatch on a 1-3/4 inch door, and the Baldwin 6301 covers entrance/apartment on a 2-1/2 inch backset for doors 1-3/4 inch and over. Standardize on the Charleston where the trim appearance is part of the unit spec; standardize on a graded lockset where the door schedule names a grade.
20) What finishes does the Emtek 3543 Charleston mortise entrance lockset come in?
Eight finishes on the Charleston 3543: Flat Black (US19), French Antique (US7), Oil Rubbed Bronze (US10B), Pewter (US15A), Polished Brass Lifetime (US3), Polished Chrome (US26), Satin Nickel (US15) and Unlacquered Brass (US3NL). The unlacquered brass will patina with handling, the lifetime polished brass will not, which is the choice most people are actually making here.
21) Is the Emtek 3543 Charleston an electronic or keypad lock?
Purely mechanical. The Charleston 3543 is a keyed brass mortise set with a cylinder and key, no keypad, no credential reader, no wiring. If you need code or card entry on a mortise prep, look instead at the Alarm Lock Trilogy DL3500CR keypad mortise lock or the Schlage CO-100 standalone electronic mortise lock.
22) The interior doors do not need to lock. What matches the Emtek 3543 Charleston on the passage doors?
For a non-locking opening the set carries mortise passage locks that use the same mortise prep approach: the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for a 1-3/4 inch door, the Hager 3810E and 3810S are Grade 1 passage mortise locks on a 2-3/4 inch backset, offered with escutcheon and with rose respectively, and the Falcon MA101 is a Grade 1 heavy duty mortise passage lock. The Emtek 3543 Charleston itself is keyed with a single cylinder, so it is the locking opening; the passage locks above handle the doors that only need to latch.
