Emtek F20-3506-75-RH-US26 – Frequently Asked Questions
1) Do I have to specify handing when ordering the Emtek 3506 Manhattan mortise entry set?
Handing is required on every Emtek mortise lock, and the 3506 Manhattan is no exception. Four choices: LH, RH, LHR and RHR, where the R versions are for out-swing doors. Stand outside the door: if the hinges are on your left and the door swings away from you, that is LHR. Get this wrong and the latch bevel faces the wrong way, so the door will not latch.
2) Which backset do I need for an Emtek Manhattan mortise entrance lockset, 2-1/2 or 2-3/4 inch?
The 3506 Manhattan comes in both 2-1/2 inch and 2-3/4 inch backsets, and the backset is set by the mortise pocket already cut in the door, not by preference. Measure from the door edge to the center of the knob or lever hole in the existing prep and order to match. On new doors, the prep is standard mortise per ANSI A115.1, so specify the backset your door shop is cutting.
3) What is the difference between the F20 and F13 functions on the Emtek 3506 mortise lock?
F20 is entrance function: key retracts the latch from outside, and the inside lever or knob always retracts it for egress. F13 is dormitory function, where the outside trim is locked or unlocked by key and stays in that state. Both are offered on the 3506 Manhattan, so pick F20 for a normal residential front door and F13 where you want the outside trim to hold unlocked during the day without a key each time.
4) Can I key the Emtek Manhattan mortise entry set to my existing Schlage keys?
The 3506 Manhattan ships with a Schlage C keyway cylinder, so it takes the same key blank as the rest of a Schlage C keyed house. It is a single cylinder keyed set, and it can be ordered keyed alike with other locks on the order or keyed to an existing code you supply.
5) Is the Emtek Manhattan mortise lock suitable for a commercial building entrance?
The 3506 Manhattan is a residential brass entry set. For a commercial opening that needs a Grade 1 heavy duty mortise lock, look at the Corbin Russwin ML2003 or the Cal-Royal NM8050 office/entrance mortise lockset, both Grade 1 and both listed for 1-3/4 inch doors. Use the Emtek where the look of solid brass trim on a home or a high-end unit door is the point.
6) Will the Emtek Manhattan mortise set drop into an existing mortise pocket?
It uses standard mortise door prep to ANSI A115.1, so it goes into a pocket cut to that standard as long as the backset matches, 2-1/2 or 2-3/4 inch. Handing and door thickness still have to be specified to suit the opening. A door mortised to a non-standard proprietary pocket will need modification.
7) What is the closest equivalent to the Emtek 3506 Manhattan mortise entrance lockset from another brand?
The Baldwin 6301 mortise lock body is the nearest peer in the decorative residential mortise category. It is an Entrance/Apartment function lock body with a 2-1/2 inch backset and a door thickness range of 1-3/4 inch and over, and it is offered in both knob-by-knob and lever-by-lever configurations under the 6301 and 6301LS part numbers. The Emtek 3506 is a keyed single-cylinder Entry mortise lock in brass, ordered in a 2-1/2 inch or 2-3/4 inch backset with an F20 Entrance or F13 Dormitory function and handing specified. The practical difference when specifying: the Emtek covers two backsets and two ANSI functions and takes a Schlage C keyway, while the Baldwin 6301 is a single 2-1/2 inch backset entrance/apartment body.
8) Which mortise lock should I use if the door is thinner than 1-3/4 inch?
The Emtek 3506 Manhattan is built around a 1-3/4 inch door as standard, with thicker doors specified at order. For a thinner opening, the Baldwin 6310 entrance/storeroom mortise lock body carries a door thickness range of 1-3/8 inch and over on a 2-1/2 inch backset, and it is available knob by knob or as the 6310190RRLS right hand reverse lever version. For an ornamental iron door, the Marks USA 21AC and 22AC entrance double cylinder mortise locks are both built for a 1 inch door. Pick by the door leaf you actually have, since a mortise body cannot be shimmed to a thinner stile.
9) Is the Emtek 3506 Manhattan mortise lock a Grade 1 commercial lock, and what do I order if my spec calls for Grade 1?
The Emtek 3506 Manhattan is a residential brass mortise entrance set, UL listed with an ANSI F20 or F13 function and standard ANSI A115.1 mortise door prep. When a drawing calls for ANSI/BHMA Grade 1, order a lock that carries the grade: the Cal-Royal NM8050 is a Grade 1 entrance/office mortise lockset for a 1-3/4 inch door, the Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset in the ML2000 Series for a 1-3/4 inch door, and the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series. All three share the standard mortise pocket, so the choice comes down to the function the opening needs.
10) I want the outside lever always locked so it only opens by key. Is the Emtek 3506 the right function?
No. The Emtek 3506 Manhattan is an Entry lock ordered as F20 Entrance or F13 Dormitory function. For an outside trim that stays locked and opens by key only, a storeroom function is the correct choice: the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option for a 1-3/4 inch door, and the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever. The Baldwin 6310 is an entrance/storeroom body if the opening also needs a decorative residential trim.
11) The Emtek 3506 needs handing specified. Is there a mortise lock I can order without knowing the hand?
Yes. The Emtek 3506 Manhattan requires handing on every order, LH, RH, LHR or RHR for an out-swing door. If the hand is not confirmed on site, a field reversible body avoids the wrong-hand return: the BEST 45H Series is a heavy duty public entrance mortise lock body with field reversible operation, and the Falcon MA101 is a Grade 1 heavy-duty mortise passage lock with field reversible operation and a fire rating. The Kaba Ilco 185 Series mortise lock is supplied with no handing. Note that those are public entrance, passage and deadbolt functions rather than the keyed single-cylinder entry the 3506 provides.
12) Can I pick a different lever or knob for the inside of the Emtek Manhattan entry set?
Yes, and it is a required choice on the order. The inside trim can be any Emtek brass knob, lever, or crystal and porcelain knob, from plain Round and Egg knobs to Windsor and Georgetown crystal, T-Bar and L-Square bar levers, and classic levers like Milano and Turino. That is how you match the inside of the front door to whatever is already on the interior doors.
13) What is the difference between the Emtek 3506 mortise entrance set and a mortise deadbolt like the Sargent 4874?
They do different jobs in the same pocket. The Emtek 3506 Manhattan is a complete keyed single-cylinder entrance set that includes the latch and strike plate and operates through a knob or lever trim. The Sargent 4874 is a double cylinder mortise deadbolt in the 4870 Series with a 2-3/4 inch backset, so it throws a bolt by key from both sides and has no latch or handle operation. The Kaba Ilco 185 Series is likewise a deadbolt function mortise lock, and it requires no handing, where the Emtek 3506 has to be ordered left hand, right hand, LHR or RHR.
14) Can I use the Emtek 3506 Manhattan for keyless or credential entry, or do I need an electronic mortise lock?
The Emtek 3506 Manhattan is a mechanical, non-electronic lock keyed to a Schlage C keyway. For code or credential entry in the same mortise pocket, the alternatives are electronic: the Accentra nexTouch NTM623-NR is a Grade 1 mortise lock with a capacitive touchscreen keypad and no deadbolt, with cylinder override; the Dormakaba E-Plex 2066 Series is an electronic pushbutton keyless mortise lock; and the Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating. Those replace the key-only operation of the 3506 rather than supplement it.
15) The opening is a bath or bedroom door that does not need a key. What replaces the Emtek 3506 there?
The Emtek 3506 Manhattan is keyed, so it is more lock than a bath or bedroom door needs. For a privacy opening, the Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for doors 1-3/4 inch to 2 inch, and the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with a deadbolt for a 1-3/4 inch door. For a closet or hall door with no locking at all, the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for a 1-3/4 inch door, and the Hager 3810S is a Grade 1 passage mortise lock with a rose and a 2-3/4 inch backset.
16) Will a Sargent 130KB mortise thumbturn or a Schlage L0170 dummy trim work as a substitute for the Emtek 3506?
No, neither is a lock. The Sargent 130KB and the Sargent 130W are mortise thumbturns, trim pieces that operate a bolt from the inside, the 130KB in the 8200 Series and the 130W with a round backplate in the 7800 Series. The Schlage L0170 is a half dummy trim in the L Series, a non-keyed lever with no latch or lock action at all, and the Falcon MESC600DT is dummy escutcheon lever trim for M9900 Series exit devices. The Emtek 3506 Manhattan is a complete keyed entrance set that includes the latch and strike plate, so the trim-only parts cannot secure the opening on their own.
17) Does a Schlage PC10 work in place of the Emtek 3506 mortise lock?
No. The Schlage PC10 is a Grade 1 cylindrical lock, passage function with a rose, for a 1-3/4 inch door, and a cylindrical lock installs in a bored hole rather than a mortise pocket. The Emtek 3506 Manhattan is a mortise lock that takes a standard mortise door prep to ANSI A115.1. If the door is already prepped for a mortise body, stay with a mortise lock such as the Schlage PM010 Grade 1 passage latch mortise lock or the Hager 3810E Grade 1 passage mortise lock with escutcheon and 2-3/4 inch backset.
18) For a dormitory or corridor door, how does the Emtek 3506 F13 compare to the Sargent 7925?
The Emtek 3506 Manhattan can be ordered in an F13 Dormitory function as a keyed single-cylinder brass entrance set in a 2-1/2 inch or 2-3/4 inch backset. The Sargent 7925 is a heavy duty Grade 1 dormitory exit function mortise lock in the 7900 Series with rose trim and a single cylinder deadbolt, catalogued for corridor and dormitory openings. The deciding factor is the deadbolt: the Sargent 7925 carries one in the body, while the 3506 is a latch-and-strike entrance set with decorative brass trim.
19) My apartment building needs decorative mortise entry hardware on unit doors. Emtek 3506 or Baldwin 6301?
Both are decorative residential mortise entry bodies. The Emtek 3506 Manhattan is a brass Entry set in eight finishes including Flat Black US19, Oil Rubbed Bronze US10B, Polished Brass Lifetime US3, Satin Nickel US15 and Unlacquered Brass US3NL, with 2-1/2 inch and 2-3/4 inch backsets, F20 or F13 function and a Schlage C keyway. The Baldwin 6301 is an Entrance/Apartment mortise lock body on a 2-1/2 inch backset for doors 1-3/4 inch and over, offered knob by knob or as the 6301LS lever by lever. For a fleet of unit doors, the 3506 gives you one keyway and one finish across many trim styles; the Baldwin fixes the backset at 2-1/2 inch.
20) I need an ADA compliant push/pull or anti-ligature mortise set instead of a knob. What are the options?
The Emtek 3506 Manhattan is operated by a knob or lever trim, so it does not cover push/pull or anti-ligature openings. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset in the 195 Series, ligature resistant and ADA compliant, in satin stainless steel. The TownSteel MRX-A-01 is a Grade 1 heavy duty ligature resistant arch trim mortise lockset in satin stainless steel for a 1-3/4 inch door, and the MRX-L-01 is the lever version in stainless steel, both passage function.
21) The door needs to release from an access control system. Is the Emtek 3506 available electrified?
The Emtek 3506 Manhattan is a mechanical brass entrance set operated by key and trim. For an opening tied to access control, the electrified mortise bodies are the substitute: the Schlage L9092EU with 03A trim is a heavy duty corridor function mortise lock with an electric lock/unlock outside lever, keyed outside, request to exit, on 12/24VDC for a 1-3/4 inch door; the Command Access ML190 Series is a heavy-duty motorized storeroom mortise lock with field selectable EL/EU operation on 24VDC; and the BEST 45HW Series is a heavy duty wired electromechanical mortise lock with 12V/24V operation.
22) What finishes does the Emtek 3506 Manhattan mortise entrance lockset come in?
Eight finishes on the Manhattan entry set: 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). Unlacquered brass is the one that will patina over time rather than hold its out-of-box look, so choose it only if you want that change.
23) Does the Emtek 3506 have a keypad or any electronics?
No electronics at all. The 3506 Manhattan is a purely mechanical keyed brass mortise set. If a keyless unit entry is what you are after in a mortise prep, the Dormakaba E-Plex 2066 pushbutton mortise lock or the Alarm Lock DL3500CR Trilogy are the keypad route, the DL3500CR being Grade 1 with classroom function for doors 1-5/8 to 1-7/8 inches thick.
