BEST 45HWDEU3H – Frequently Asked Questions

1) Will the BEST 45HW electrified mortise lock fit a standard 1-3/4 inch commercial door?
Yes. The 45HW is built for standard 1-3/4 inch doors, with thick door options available up to 5 inches. Backset is 2-3/4 inches and the faceplate measures 8 x 1-1/4 x 1/16 inches, so it drops into the same mortise pocket layout as a standard heavy duty commercial mortise prep. If your doors run thicker than 1-3/4, the thick door option has to be specified at order time, not added later.
2) What is the difference between EL and EU on the BEST 45HW, and which one do I need for a fire-rated stair door?
On the 45HW wired mortise lock, EU functions are electrically unlocked, meaning fail secure: cut power and the outside lever stays locked. EL functions are electrically locked, meaning fail safe: cut power and the outside lever unlocks. Fail safe (EL) is what gets specified where people must be released on a fire alarm or power loss. Fail secure (EU) is the usual choice for a stair or exterior opening you want to stay locked in a power outage. You pick one at order time as the lock type option; it is not field-changeable on this series.
3) Does the BEST 45HW electric mortise lock need to be ordered handed?
Handing matters here. You specify left hand, right hand, left hand reverse, or right hand reverse when you order. The latchbolt itself is oil-impregnated and reverses without opening the case, so a latch hand mix-up is recoverable in the field, but the trim and function are ordered to the hand of the opening. Measure the door before you order: on a reverse-bevel opening (an outswing door) you want the reverse designation.
4) Will the BEST 45HW accept my existing BEST small format interchangeable cores?
Yes, if you order the 7-pin housing version. That cylinder option ships as an SFIC prep less core and accepts all BEST cores, so it drops straight into a facility already keyed on BEST SFIC. There is also a non-IC and LFIC competitive cylinder version, ordered less LFIC core, for buildings standardized on another manufacturer's large format core. Either way the core is not included, so pull it from your existing stock or order it alongside. Keying can be specified keyed different or keyed alike.
5) Will the BEST 45HW latch into the strike that is already in my frame?
The 45HW throws a 3/4 inch latchbolt, and the deadbolt versions throw a full 1 inch, both stainless steel. Those are standard heavy duty mortise throws, so an existing ANSI mortise strike with the correct lip and a deep enough deadbolt pocket will normally take it. What decides it is the frame prep, not the bolt: the faceplate is 8 x 1-1/4 x 1/16 inches, so if you are replacing a mortise lock with the same faceplate footprint the frame side usually carries over. If you are moving up from a cylindrical lock, the frame needs a new mortise strike prep.
6) Can I get door position and latch monitoring built into the BEST 45HW mortise lock?
Yes, and they are separate order options you tick individually: request to exit (RX), latch status monitor, and door status monitor. Adding them at the lock saves running a separate door contact and REX device on the opening. A visual indicator is also available as an add option. Decide these before the order goes in, because they are internal switches, not accessories you bolt on afterward.
7) Is the BEST 45HW approved for use on a fire door in California or New York City?
The 45HW is UL listed under GYQS for electrically-controlled singlepoint locks and latches, and it is approved by the California State Fire Marshal under section 13144.1 of the California Health and Safety Code, CSFM listing No. 4136-1175:101. It also holds approval from the City of New York Board of Standards and Appeals under calendar number 49-88-SA. Check the CSFM listing for the allowable values and conditions of use on your specific opening.
8) Should I use a wired electric mortise lock or a standalone battery keypad lock for my access control job?
The 45HW is a wired lock with no battery, so it needs power run to the door and a head-end system to control it, but it never needs a battery change and it reports back through RX and door or latch status monitoring in real time. A standalone keypad lock like the Dormakaba E-Plex 2066 or the Alarm Lock DL3500CR is the alternative when running wire to the opening is not practical, and those manage users at the lock itself. If the opening is already on a card access system, or you need remote lock and unlock, the wired 45HW is the right shape. If it is an isolated door with no cabling path, go standalone.
9) What is the closest equivalent to a BEST 45HW wired electromechanical mortise lock from another manufacturer?
The Schlage L9092EU with 03A trim is the nearest match. Like the 45HW, it is a heavy duty mortise lock body with an electrically controlled outside lever, runs on 12 or 24VDC, and is offered with request to exit. The 45HW covers the same electrical range at 12 or 24 volts AC or DC and offers request to exit, latch status monitor and door status monitor as ordering options. The Schlage is fitted for 1-3/4 inch doors in corridor function; the 45HW uses a 2-3/4 inch backset and takes either a 7-pin BEST SFIC housing or a non-IC and LFIC competitive cylinder.
10) I need a fail-safe/fail-secure mortise lock but I want to pick the mode in the field instead of at order time. What are my options?
The Command Access ML190 is the one to look at. It is a heavy-duty motorized mortise lock with field selectable EL/EU operation on 24VDC, so a single unit can be set electrically locked or electrically unlocked after it is on the door. The BEST 45HW splits that choice at order time: EL functions are electrically locked (fail safe) and EU functions are electrically unlocked (fail secure), selected as the Lock Type Option when the lock is specified. The 45HW does accept either 12 or 24 volts AC or DC, where the ML190 is specified at 24VDC.
11) The opening has no power run to the door frame. What mortise lock should I use instead of a wired electromechanical one?
A standalone battery or self-powered lock avoids the wire pull entirely. The Alarm Lock DL3500CR is a Grade 1 classroom-function electronic mortise lock with 300 user codes, and the Alarm Lock DL2700CR is a Grade 1 classroom electronic mortise lock with a weatherproof design; both fit 1-5/8 inch to 1-7/8 inch doors. The Dormakaba PowerPlex P2066 is another route. The BEST 45HW is not battery operated and requires a 12V or 24V AC/DC supply at the door plus a Temperature Control Module, so it belongs on an opening where power and access control wiring are already planned.
12) We want a wireless lock tied to an access control system rather than running wire. What replaces a wired electromechanical mortise lock?
Wireless mortise locks keep the system tie without the wire pull to the door. The Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and a mobile-enabled deadbolt with LED on Greenwich trim, right hand, with a 3 hour fire rating. The Alarm Lock DL1300NW is a Trilogy Networx wireless electronic mortise lock with keypad, built for Adams Rite deadlatches. The BEST 45HW is the wired path instead, with a 2-3/4 inch backset lock body and an 8 inch H x 1-1/4 inch W x 1/16 inch T faceplate.
13) We use small format interchangeable cores across the facility. Which electronic mortise locks accept our existing cores?
The BEST 45HW ships SFIC prep less core and can be ordered with a 7-pin housing that accepts all BEST cores, or with a non-IC and LFIC competitive cylinder housing less LFIC core, so an existing keying system carries straight over and units can be specified keyed alike or keyed different. Among mechanical peers, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset offered with an interchangeable core option for 1-3/4 inch doors. Credential-based locks such as the Accentra NTM623-NR nexTouch Generation 3 mortise lock provide a cylinder override rather than a full mechanical keying program.
14) The lock has to go in a narrow aluminum storefront stile. Will an electrified heavy duty mortise lock fit, or do I need something else?
A heavy duty mortise case sized for a wood or hollow metal door is the wrong tool for a narrow aluminum stile. The Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock specified for wide stile, the Alarm Lock DL1300NW Trilogy Networx wireless electronic mortise lock is built for Adams Rite deadlatches, and the Kaba Ilco BR Series is a glass door bottom rail lock. The BEST 45HW is a commercial heavy duty mortise lock on a 2-3/4 inch backset with an 8 inch faceplate, sized for standard 1-3/4 inch doors with thick door options to 5 inches.
15) Which electronic mortise locks carry a Grade 1 rating for a heavy traffic commercial opening?
Among electronic mortise locks, Grade 1 units include the TownSteel FME-2000 and FME-4000, both heavy duty classroom-function locksets with RFID technology for 1-3/4 inch doors, the Schlage CO-100 standalone electronic mortise lock in privacy function, the Dormakaba E-Plex E5086 entry/egress pushbutton and card lock, and the Alarm Lock DL2700CR and DL3500CR classroom locks. Not every electronic mortise lock is in that class: the Dormakaba Saffire LX-I-M002 RFID mortise lockset with BLE mobile access is BHMA Grade 2, and the Schlage LEBMB-ADD mobile-enabled mortise lock is Grade 2 with a 3 hour fire rating. The BEST 45HW is a heavy duty commercial lock, UL listed for GYQS electrically-controlled singlepoint locks and CSFM approved.
16) Do I have to order a Temperature Control Module separately with the BEST 45HW?
No. All W-series BEST locks require a Temperature Control Module, and the TCM plus its connector come standard in the box with every 45HW order. Budget the wiring and a spot for the module in your rough-in, but there is nothing extra to add to the purchase order for it.
17) What functions does the BEST 45HW electric mortise lock come in?
Six: single key latch, double key latch, keyless latch, single key deadbolt, double key deadbolt, and keyless deadbolt. Latch functions give you a latchbolt controlled electrically at the outside lever. Deadbolt functions add the 1 inch stainless deadbolt for openings where a positive locked bolt is required. Keyless versions have no cylinder at all, which suits doors controlled entirely from the access control head end, and the keyed configuration is single cylinder.
18) Is there an antimicrobial finish option on the BEST 45HW for a hospital?
Two of them: 626AM satin chrome antimicrobial and 630AM satin stainless steel antimicrobial, meant for healthcare and other high-touch openings. The full finish range also covers 626 satin chrome, 630 satin stainless, 690 statuary dark bronze, 606 satin brass, 612 satin bronze, 613 oil-rubbed satin bronze, 619 satin nickel, 605 bright brass, 611 bright bronze, 625 bright chrome, and 618 bright nickel, so a hospital can run AM finishes on patient-contact doors and match the rest of the building on the same lock body.
19) What is a comparable wired 12/24V electric mortise lock to the BEST 45HW from another brand?
Two close peers if BEST does not suit the keying on your building. The Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit and 12/24VDC operation, listed for 1-3/4 inch doors. The Command Access ML190 Series is a motorized mortise lock with field selectable EL/EU operation on 24VDC, in a storeroom function. The Command Access unit is the one to look at if you want to pick fail safe or fail secure in the field rather than at order time, since the 45HW's EL or EU is set by the model you order.
20) What trim and lever styles can I get on the BEST 45HW to match the other doors in my building?
Lever styles run to seven: contour with angle return, curved with return, curved without return, gull wing, solid tube with return, solid tube without return, and a round knob. Trim choices are 2-3/4 inch concave, 2-3/4 inch flat, 3-1/2 inch flat, forged, forged concealed cylinder, and wrought. That range is what lets an electrified opening look identical to the mechanical BEST mortise locks on the rest of the floor, since the 45HW uses the same construction standards as the mechanical mortise line.
21) I need a mechanical mortise lock, not an electrified one, on the same 2-3/4 inch backset. What are my options?
If the opening does not need electric control, plenty of Grade 1 mechanical mortise locks cover the standard functions. The Hager 3800 Series runs a 2-3/4 inch backset in passage, privacy, and office functions for 1-3/4 to 2-1/2 inch doors. Corbin Russwin ML2003 is a Grade 1 classroom mortise for 1-3/4 inch doors, and the Cal-Royal NM8080 covers storeroom with an interchangeable core option. Going mechanical drops the power supply, TCM, and wiring entirely, which is the bulk of the install cost on an electrified opening.
22) What is the difference between a wired electromechanical mortise lock and a card or keypad lock at the door?
They solve access control at different points. The BEST 45HW is wired back to a panel and power supply, drawing 0.60 amps at 12 volts or 0.45 amps at 24 volts, with the credential decision made upstream; monitoring comes from the request to exit, latch status monitor and door status monitor options. A credential-at-the-door lock keeps the reader and decision in the lock body: the Schlage CO-100-MS-40-KP is a Grade 1 standalone electronic mortise lock with a keypad reader in privacy function, the TownSteel FME-2000 is a Grade 1 mortise lockset with RFID technology in classroom function, and the Dormakaba E-Plex E5086 is a Grade 1 pushbutton and card mortise lock. Wired suits an integrated system; credential-at-the-door suits openings run on their own.
23) If the door does not actually need electronic control, what mechanical mortise lock takes the same 2-3/4 inch backset prep?
Several Grade 1 mechanical mortise locks work in a 2-3/4 inch backset prep. The Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon, non-keyed, at 2-3/4 inch backset for 1-3/4 inch to 2-1/2 inch doors, and the Hager 3810S is the Grade 1 passage version with rose at the same backset. On the keyed side, the Accentra 8805FL is a Grade 1 storeroom mortise lock from the 8800 Series with an Arcadia lever, and the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors. The BEST 45HW carries the same 2-3/4 inch backset but adds the 12V/24V control and the wiring, power supply and Temperature Control Module that go with it.
24) Which mortise products look like substitutes for an electrified mortise lock but will not control the opening?
Watch for trim and dummy pieces that share the mortise name without a working latch or bolt. The Schlage L0170 is a half dummy trim, a Grade 1 mortise non-keyed lever with no latching function, and the Falcon MESC600DT is a dummy escutcheon lever trim for M9900 Series exit devices. The Emtek 3102 Memphis, 3104 Hamilton and 3106 Manhattan mortise entrance locksets are also dummy function. Separately, the Sargent 130KB and 130W are mortise thumbturns, standard duty trim rather than a lock body. The BEST 45HW is a complete keyed mortise lock body with a stainless steel deadbolt at 1 inch throw and a 3/4 inch latchbolt throw under electric control.
25) Is a mortise deadbolt a substitute for an electrified mortise lockset on a controlled opening?
No, they do different jobs. The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset, the Kaba Ilco 185 Series is a deadbolt-function mortise lock with no handing, and the Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad for 1-5/8 inch to 1-7/8 inch doors. Each secures the door but provides no latching lever operation. The BEST 45HW is built in deadbolt and latch variations together, with double key latch, double key deadbolt, single key deadbolt, single key latch, keyless deadbolt and keyless latch functions, so the bolt and the electrically controlled lever operation live in one case.
26) For a behavioral health or patient room, is a wired electromechanical mortise lock the right choice or is there a better fit?
For ligature-resistant openings, go to the anti-ligature mortise families. The TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel, passage function for 1-3/4 inch doors, and the MRX-A-01 is the arch trim version in satin stainless. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant in satin stainless steel. Where the opening is a healthcare corridor rather than a patient room, the BEST 45HW is offered in 626AM satin chrome and 630AM satin stainless antimicrobial finishes for high-touch areas.
27) We need visual occupancy indication on a classroom or restroom door. Does an electrified mortise lock cover that, or is there a dedicated lock?
Both routes exist. The Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset for 1-3/4 inch doors with an ANSI strike and a steel escutcheon measuring 8-1/2 inch H x 2-3/4 inch W x 7/16 inch. The Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors if the requirement is privacy rather than indication. The BEST 45HW can be ordered with a visual indicator as an option alongside its electric control, so an opening that needs both indication and access control does not require two products.
28) Can I use a decorative or ornamental iron mortise lock in place of a commercial electrified mortise lock?
Those are built for different doors. The Baldwin 6301 entry/apartment and 6310 entry/storeroom mortise lock bodies use a 2-1/2 inch backset, and the Marks USA 21AC and 22AC ornamental iron entrance mortise locks are specified for 1 inch thick doors. Backset and door thickness alone rule them out of a standard commercial prep. The BEST 45HW is a commercial heavy duty lock on a 2-3/4 inch backset, handed left, right or reverse, with lever styles including gull wing, curved with return, solid tube and round knob and trim in flat, concave, forged or wrought.
29) For a simple corridor or closet door in the same building, what mortise lock matches the prep without the electronics?
For non-secured openings in the same prep, the Falcon MA101 is a Grade 1 heavy-duty mortise passage lock with field reversible operation and a fire rating, the Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, for 1-3/4 inch doors, and the Hager 3810E is a Grade 1 passage mortise lock with escutcheon on a 2-3/4 inch backset for 1-3/4 inch to 2-1/2 inch doors. If the door is prepped cylindrical rather than mortise, the Schlage PC10 is the Grade 1 passage cylindrical equivalent. The BEST 45HW belongs on the openings in that same building that need 12V or 24V electric control and monitoring.
30) Is the BEST 45HW mortise lock heavy duty enough for a school corridor or apartment entry?
It is rated heavy duty and commercial. The case is cold rolled steel with zinc dichromate plating, and both the deadbolt and latchbolt are stainless steel. That is the construction you want on high-traffic openings such as school corridors, multi-tenant residential entries, and healthcare doors. For a light residential or decorative opening, this is more lock than the job needs.
