Emtek F20-3508-75-RH-US19 – Frequently Asked Questions
1) Do I have to specify handing when ordering the Emtek 3508 Craftsman mortise entry set?
Handing is required, and there is no field-reversing your way out of it. The 3508 is ordered as LH, RH, LHR or RHR, where the R versions are for out-swing doors. Stand outside the opening: if the hinges are on your left and the door swings away from you, that's LH; hinges left and swinging toward you is LHR. Get it backwards and the latch bevel faces the wrong way and won't catch the strike.
2) Will the Emtek 3508 mortise lockset fit my existing door prep?
The 3508 uses the standard mortise pocket prep to ANSI A115.1, so a door already mortised for a common commercial or residential mortise lock takes it without recutting the pocket. What you do have to match is backset: it comes in 2-1/2 inch and 2-3/4 inch, and the pocket depth on your door decides which one you order. Door thickness is 1-3/4 inch as standard; thicker doors have to be called out on the order.
3) Emtek 3508 F20 Entrance vs F13 Dormitory function - which one do I want?
Both are on the 3508, and they behave differently on the inside. F20 Entrance is the normal house or apartment front door: key outside, thumbturn or inside lever always gives free egress, and the outside can be left unlocked. F13 Dormitory is the corridor function used where a door must relock itself behind the occupant, so the outside stays secure unless it is keyed open. For a residential front entry, F20 is the usual pick.
4) Is the Emtek 3508 mortise entrance lockset fire rated?
The 3508 mortise body carries a UL 180 minute fire rating and is a UL Listed mortise lock, which covers a 1-1/2 hour rated opening such as a stair or corridor door in a multi-family building.
5) Can I key the Emtek 3508 to the same key as the rest of my Schlage-keyed doors?
The 3508 ships with a Schlage C keyway cylinder, so it keys into an existing Schlage C system. It is single cylinder and keyed, and on the order you choose keyed different or keyed alike across the set, with an option to key to a specific code if you are matching an existing bitting. That is what makes it workable for a landlord standardizing several units on one key.
6) Is the Emtek 3508 mortise lock heavy duty enough for a commercial building entrance?
The 3508 is a residential-classified brass entry set. It suits a house, a townhome, or a boutique multi-family front door where the look matters. For a high-traffic commercial opening you want a Grade 1 commercial mortise lockset instead: the Corbin Russwin ML2003 or the Cal-Royal NM8050 Office/Entrance, both Grade 1 mortise locksets for 1-3/4 inch doors, or the Accentra 8805FL storeroom lock from the 8800 Series.
7) What is a comparable mortise entry lock body to the Emtek 3508 Craftsman if I need a decorative knob or lever set on a residential entry door?
The Emtek 3508 Craftsman is a complete mortise entrance set with entry function, sold with latch and strike plate, ordered with a knob, crystal or lever inside trim. The closest residential-style peer is the Baldwin 6301 mortise lock body, which is an entrance/apartment function with a 2-1/2 inch backset and is offered knob by knob or, as the 6301LS, lever by lever. Both suit doors 1-3/4 inch and over. The 3508 covers both 2-1/2 inch and 2-3/4 inch backsets, so on a door already mortised for 2-3/4 inch it drops in without re-prepping, while the Baldwin 6301 is a 2-1/2 inch backset lock.
8) I need a keyed mortise lock that always stays locked outside on a commercial back door. Is the Emtek 3508 the right choice?
The Emtek 3508 Craftsman is a single cylinder entry mortise set built as residential brass door hardware, in F20 entrance or F13 dormitory function. For an opening that must stay locked from the outside at all times, a storeroom function is the closer match: the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option for doors 1-3/4 inch thick.
9) I want a decorative mortise entry lock but my door is only 1 inch thick. Will the Emtek 3508 work?
The Emtek 3508 Craftsman is standard for 1-3/4 inch doors with thicker doors specified at order. For thin ornamental iron doors, the Marks USA 21AC is an entrance double cylinder Unilock ornamental iron mortise lock with round knob for 1 inch doors, and the Marks USA 22AC is the 22 Series entrance double cylinder ornamental iron mortise lock with round knob, also for 1 inch doors. Both are double cylinder, keyed on each side, while the 3508 is single cylinder.
10) The Emtek 3508 requires handing. What mortise locks can I order without knowing the hand?
The Emtek 3508 Craftsman requires handing on every order, specified as LH, RH, LHR or RHR for out-swing doors. Where the hand is not yet known, the BEST 45H Series heavy duty mortise lock body in public entrance function is field reversible, the Falcon MA101 Grade 1 heavy duty passage mortise lock is field reversible, and the Kaba Ilco 185 Series mortise locks ship with no handing.
11) Does the Emtek 3508 Craftsman work on a fire rated door, or do I need a different mortise lock?
The Emtek 3508 Craftsman is a UL listed mortise lock with a UL 180 minute fire rating on standard ANSI A115.1 mortise prep. Where a longer rating is required, the Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 3 hour fire rating, and the Schlage Electronics LEBMB-ADD mobile-enabled mortise lock is Grade 2 with a 3 hour fire rating for 1-3/4 inch doors. The Falcon MA101 Grade 1 heavy duty passage mortise lock is also fire rated.
12) What comes in the box with the Emtek 3508 entry set, and what else do I need to buy?
It is sold as a complete set: mortise lock body with latch, strike plate, and the exterior Craftsman trim. You pick the inside knob or lever style as part of the order, from a range that runs from Craftsman-appropriate options like the Arts and Crafts Lever and the Ace Knurled Knob through to crystal and porcelain knobs. Nothing further is required for a standard 1-3/4 inch door with an existing mortise pocket.
13) I'm replacing a Baldwin mortise lock body - is the Emtek 3508 a straight swap?
Not automatically. Both are ordered by backset, and the Baldwin 6301 Entry/Apartment and 6310 Entry/Storeroom bodies are 2-1/2 inch backset, which the 3508 also offers, so the pocket position can line up. What differs is trim: the 3508 is a complete entry set with its own Craftsman exterior plate, so the existing escutcheon cutout and through-bolt holes may not match. If you only want the lock body and are keeping Baldwin trim, order the Baldwin body.
14) Should I use a mortise entry set like the Emtek 3508 or a cylindrical lock on my front door?
A mortise lock goes into a rectangular pocket routed into the door edge, not a round bore, so it only makes sense where the door is already mortised or you are prepared to cut the pocket. In exchange you get a heavier body, a keyed cylinder and thumbturn in one case, and the long Craftsman escutcheon look. If your door has a standard 2-1/8 inch cross bore, a cylindrical lock is the far easier retrofit. Also plan the backset before you cut: the 3508 is 2-1/2 or 2-3/4 inches.
15) What mortise lock should I use instead of the Emtek 3508 on a classroom or office door in a school?
The Emtek 3508 Craftsman is an entry set for residential openings in F20 entrance or F13 dormitory function. Classroom and office openings call for a function built for them: the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series for 1-3/4 inch doors, the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch, and the Cal-Royal NM8050 is the Grade 1 office/entrance version with auxiliary deadlatch, also for 1-3/4 inch doors.
16) The Emtek 3508 is keyed. What is the equivalent if I only need a latch with no key on the same mortise prep?
The Emtek 3508 Craftsman is a keyed single cylinder entry mortise set on standard ANSI A115.1 mortise prep. Where no key is wanted, the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, the Hager 3810S is a Grade 1 passage mortise lock with rose and 2-3/4 inch backset, and the Hager 3810E is the same passage function with an escutcheon; both Hager 3800 Series passage locks cover 1-3/4 inch to 2-1/2 inch doors. The Falcon MA101 is a Grade 1 heavy-duty passage mortise lock with field reversible operation, which removes the handing call the 3508 requires.
17) Can I use the Emtek 3508 Craftsman on a bedroom or bathroom door?
The Emtek 3508 Craftsman is a keyed entry mortise set with a Schlage C keyway, so it locks with a key rather than a thumbturn privacy function. For bed and bath openings 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 deadbolt for 1-3/4 inch doors.
18) What is the difference between the Emtek 3508 Craftsman and an electronic mortise lock like the Alarm Lock DL3500CR or Schlage CO-100?
The Emtek 3508 Craftsman is a non-electronic brass mortise entrance set keyed to a Schlage C keyway, opened by key and trim only. Electronic mortise locks manage access by code or credential instead: the Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes and classroom function for doors 1-5/8 inch to 1-7/8 inch, the Schlage CO-100 is a Grade 1 standalone electronic mortise lock with keypad reader in privacy function for 1-3/4 inch doors, and the BEST 45HZ EZ Series is an electronic keypad mortise lock with key override. Note the DL3500CR door range stops at 1-7/8 inch, while the 3508 is standard for 1-3/4 inch doors and can be specified thicker.
19) Is a Sargent 4874 mortise deadbolt a substitute for the Emtek 3508 Craftsman entry set?
No. The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset in the 4870 Series, and the Kaba Ilco 185 Series is likewise a deadbolt function mortise lock supplied with no handing. Those are deadbolt-only bodies with no latch or operating trim. The Emtek 3508 Craftsman is a complete entrance set that includes the latch and strike plate and takes a knob, crystal or lever for inside trim, and it requires handing to be specified.
20) The Emtek 3508 offers an F13 dormitory function. What is the commercial equivalent for a dormitory corridor door?
The Emtek 3508 Craftsman offers ANSI F13 dormitory alongside F20 entrance, in a brass residential set. On the commercial side, the Sargent 7925 is a Grade 1 heavy duty corridor/dormitory function mortise lock in the 7900 Series with rose trim and a single cylinder deadbolt, which adds a separate deadbolt the 3508 does not carry.
21) My door is prepped for a cylindrical lock, not a mortise pocket. What should I order instead of the Emtek 3508?
The Emtek 3508 Craftsman needs a standard mortise pocket cut to ANSI A115.1. A door bored for a cylindrical lock will not take it without new prep. The Schlage PC10 is a Grade 1 passage cylindrical lock with rose for 1-3/4 inch doors and fits cylindrical bored prep instead.
22) Is the Emtek 3508 Craftsman suitable for a narrow stile aluminum storefront door?
The Emtek 3508 Craftsman is a brass residential mortise entrance set on standard ANSI A115.1 mortise prep with 2-1/2 inch or 2-3/4 inch backsets, sized for 1-3/4 inch doors as standard. Aluminum storefront openings are served by different bodies: the Alarm Lock DL1300NW Trilogy Networx wireless electronic mortise lock is made for Adams Rite deadlatches, and the Kaba Ilco BR Series is a glass door bottom rail lock.
23) For a behavioral health or hospital corridor, is the Emtek 3508 Craftsman an option or should I look at ligature resistant trim?
The Emtek 3508 Craftsman is a brass entry set ordered with knobs, crystal knobs or levers, which are projecting trim styles. Openings that require ligature resistant trim are served by the TownSteel MRX-A-01, a Grade 1 heavy duty ligature resistant arch trim mortise lockset in passage function for 1-3/4 inch doors, the TownSteel MRX-L-01 anti-ligature lever version, and the Marks USA 5PDN, a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel.
24) I have a Baldwin 6310 storeroom mortise body on one door and want a matching-function Emtek set on the next. Do they match?
Not on 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, with the 6310190RRLS as the right hand reverse lever by lever version. The Emtek 3508 Craftsman is an entrance set in ANSI F20 entrance or F13 dormitory function, keyed single cylinder to a Schlage C keyway, with handing specified as LH, RH, LHR or RHR. For a storeroom function alongside it, the Baldwin 6310 family or the Cal-Royal NM8080 Grade 1 storeroom mortise lockset is the closer match.
25) Which mortise lock should I specify if the opening needs to be wired to an access control system rather than keyed?
The Emtek 3508 Craftsman is a mechanical keyed set with no electronic operation. For an electrified opening, the BEST 45HW Series is a wired electromechanical heavy duty mortise lock with 12V/24V operation, the Command Access ML190 is a heavy-duty motorized mortise lock with field selectable EL/EU operation on 24VDC in storeroom function, and the Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit on 12/24VDC for 1-3/4 inch doors.
26) What finishes does the Emtek 3508 Craftsman entry set come in, and will they match my other Emtek hardware?
Four finishes: Flat Black (US19), Oil Rubbed Bronze (US10B), Satin Nickel (US15), and Unlacquered Brass (US3NL). Those are standard finish codes, so a US10B 3508 matches US10B on the rest of your Emtek trim. Note the unlacquered brass is a living finish and will darken with handling, which is usually the point on an Arts and Crafts opening but is worth knowing before you put it beside lacquered hardware.
27) Does the Emtek 3508 entry set need any wiring or power?
No power, no wiring, no batteries. The 3508 is a purely mechanical brass mortise entry set with a keyed cylinder. If you are after keypad or credential access on a mortise prep, that is a different product entirely, something like the Dormakaba E-Plex 2066 electronic pushbutton mortise lock or the Alarm Lock DL3500CR Trilogy.
28) Is a Schlage L0170 dummy trim an alternative to the Emtek 3508 for a fixed inactive door leaf?
They do different jobs. The Emtek 3508 Craftsman is a keyed entry mortise set with latch and strike, and handing must be specified. The Schlage L0170 is a Grade 1 non-keyed half dummy trim lever in the L Series for 1-3/4 inch doors, and the Falcon MESC600DT is a dummy escutcheon lever trim for M9900 Series exit devices. Dummy trim does not latch and carries no cylinder, so it suits a fixed leaf rather than an operating entry.
