BEST 45H7R15H626 – Frequently Asked Questions

1) Does the classroom function on the BEST 45H let a teacher lock the door from inside the room?
No. Classroom function means the outside lever is locked and unlocked by key from the corridor side only, and the inside lever always retracts the latch for free egress. A teacher cannot secure the door without stepping into the hallway with a key. If your district wants lockdown from inside the classroom, the 45H classroom is the wrong function for that requirement, look at a classroom security function with an inside keyway or an electronic classroom lock such as the TownSteel FME-4000 electronic intruder classroom mortise lock.
2) Does the BEST 45H mortise lock come with a cylinder or core?
It ships prepped for a BEST small format interchangeable core, less core. You order the core separately and key it into your existing system, which is what most facilities running BEST SFIC already want. Budget for that core on the same order or the lock arrives unable to be locked.
3) Is the BEST 45H handed, or do I need to specify left or right?
Non-handed. The latch is reversible and rotates 180 degrees without opening the case, so one lock covers either swing and you can flip it in the field. For a property manager stocking spares across a building, that means a single part number on the shelf instead of a left and a right.
4) Will the BEST 45H latch into the strike already in my frame?
The latchbolt is solid stainless with a 3/4 inch throw and the deadbolt throws 1 inch, both on a 2-3/4 inch backset. An existing ANSI mortise strike prepped for a 2-3/4 inch backset lock with a deadbolt cutout will take it. A strike with no deadbolt opening will not, the classroom function only uses the latchbolt and auxiliary bolt, but if you reuse a frame that had a deadbolt lock, confirm the lip projection still lets the 3/4 inch latch seat fully.
5) A spec calls for Grade 1 security, not just Grade 1 strength. Does the BEST 45H meet it or is another product needed?
The BEST 45H is ANSI A156.13 Series 1000, Grade 1 operation and strength, Grade 2 security. To reach Grade 1 security it needs a drill resistant core (1CD, 1CDP, 1CDF, or 1CDX) with escutcheon trims, or a 1EK7K4 high security cylinder with sectional trims. The 47H Series is ANSI A156.13 Series 1000 Grade 1 for operational, strength, and security as built. Peers carrying a Grade 1 listing include the Cal-Royal NM8070 classroom and the Corbin Russwin ML2003 classroom lockset.
6) What is the closest cross-brand equivalent to a BEST 45H classroom mortise lock?
The Cal-Royal NM8070 and the Corbin Russwin ML2003 are the nearest peers. Both are Grade 1 classroom-function mortise locksets, and both are listed for 1-3/4 inch doors, which is the standard door thickness the BEST 45H is configured for. The BEST 45H carries a 2-3/4 inch backset and comes with SFIC prep less core, so if the building is already keyed on a small format interchangeable core system, the 45H drops into that keying program directly while the peers would need their own cylinder decision.
7) What should be used instead of a BEST 45H classroom lock on an opening that needs credential or code access?
The BEST 45H is a mechanical, keyed lock with no electronics. For a classroom opening that needs codes or credentials, the Alarm Lock DL3500CR is a Grade 1 electronic classroom mortise lock with 300 user codes, and the TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID. The TownSteel is listed for 1-3/4 inch doors, matching the 45H standard configuration, while the Alarm Lock DL3500CR is listed for doors 1-5/8 to 1-7/8 inch, so verify the leaf before ordering it.
8) A door needs to lock down from inside the classroom. Does the BEST 45H do that, or is there another option?
The BEST 45H is a classroom function lock, which is key-operated from the outside. For an intruder lockdown initiated at the door, the TownSteel FME-4000 is an electronic intruder classroom mortise lockset with RFID, Grade 1 heavy duty, for 1-3/4 inch doors. The Alarm Lock DL2700CR is another Grade 1 classroom electronic mortise lock and is built weatherproof, which suits an exterior classroom or portable entrance; it is listed for 1-5/8 to 1-7/8 inch doors.
9) Which mortise locks look like a substitute for a BEST 45H classroom lock but are not?
Several mortise products in the same size class do not secure a classroom door. The Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, and the Hager 3810S is a Grade 1 passage mortise lock with rose and a 2-3/4 inch backset - a matching backset, but no keyed function at all. The Falcon MA101 is a Grade 1 heavy duty mortise passage lock. The Schlage L0170 is half dummy trim, Grade 1 heavy duty, with no latching function. The BEST 45H is keyed with a single cylinder, so none of these carry the outside key control a classroom function requires.
10) An access control system needs to release the lever electrically. What replaces a BEST 45H there?
The BEST 45H is a mechanical lock with no electrification. For an electrically controlled lever, the Command Access ML190 is a heavy duty motorized mortise lock with field selectable EL/EU operation on 24VDC in a storeroom function. The Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit, running 12 or 24VDC on 1-3/4 inch doors. Field selectable EL/EU on the Command Access unit lets one part cover both fail-secure and fail-safe, while the Schlage arrives configured with RX signaling built in.
11) What replaces a BEST 45H on a door thicker than 1-3/4 inches?
The BEST 45H itself covers it - the standard configuration is for 1-3/4 inch doors and a thick door configuration is available for doors up to 5 inches, with the thickness specified at time of order. Among the peers, the Hager 3810E and 3810S list 1-3/4 to 2-1/2 inch and the Baldwin 6301 lists 1-3/4 inch and over, while the Cal-Royal NM8070 and Corbin Russwin ML2003 list 1-3/4 inch. For an unusually thick leaf, the 45H thick door option is the one that scales furthest.
12) What do I have to specify when ordering a BEST 45H classroom mortise lock?
Four things decide the part: finish, lever or knob style, rose size, and door thickness if it is over 1-3/4 inches. Finishes run 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 oxidized satin bronze oil rubbed, 618 bright nickel, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, 630 satin stainless, 690 statuary dark bronze, plus 626AM and 630AM antimicrobial. Trim choices are 12 solid tube no return, 3 solid tube with return, 4 round knob, contour with angle return, curved with return, curved without return, and gull wing. Roses come as H 2-3/4 flat, R 2-3/4 concave, or S 3-1/2 flat. Core is ordered separately.
13) Which finish should I pick for a hospital or a school cafeteria door?
626AM satin chrome or 630AM satin stainless, both with the UltraShield antimicrobial coating that inhibits bacterial and microbial growth on the hardware surface. BEST calls these out for hospital and elderly care, education, transportation, food service and hospitality. If cleanliness is not driving the job, plain 626 or 630 gives the same look. Two finishes are worth knowing about before you standardize a building: 613 oxidized satin bronze is designed to wear to an antique appearance over time, and 690 stays a dark brown, so neither will hold a uniform match against newer hardware the way a plated finish does.
14) Can I get a classroom mortise lock with a keypad or card reader instead of a key?
Not in the 45H, it is a mechanical lock with no electronic option. For credential-based classroom control, the TownSteel FME-2000 is a Grade 1 classroom mortise lockset with RFID for 1-3/4 inch doors, and the Alarm Lock DL3500CR is a Grade 1 Trilogy electronic classroom mortise lock with 300 user codes fitting 1-5/8 to 1-7/8 inch doors. Mechanical 45H is still the choice where you want no batteries in the door and keying tied to an existing BEST core system.
15) I need the same lock body on other doors in the building but not classroom function. What are my options?
Function is what you change, not the lock family, and the 45H covers a range of them. If you are matching finish and trim across a building and need other functions from other lines we carry, the Cal-Royal NM series is a straight parallel set: NM8050 office/entrance, NM8080 storeroom with interchangeable core option, NM8440 privacy with deadbolt, all Grade 1 for 1-3/4 inch doors. Hager's 3800 Series covers non-keyed openings, the 3810S passage with rose and the 3850E office with escutcheon, both on a 2-3/4 inch backset like the 45H.
16) Is the BEST 45H heavy enough for a high traffic corridor, and does it meet accessibility requirements?
Built for it. The case, cover and armored front are 0.095 inch cold rolled steel, zinc dichromate plated against corrosion, and the hub runs on roller bearings for cycle life. The latch is solid one-piece stainless with oil impregnation for anti-friction operation and 50 percent more contact surface at the strike. The armored front wraps the latch and deadbolt for lateral strength. BEST states the design and operation of the mortise lock meets the intent of ANSI A117.1 section 404.2.6, the accessibility standard for door hardware operation.
17) Will the 2-3/4 inch rose on the BEST 45H cover the marks left by the old escutcheon trim?
Probably not. The R rose is 2-3/4 inch concave and the H is 2-3/4 inch flat, both small round trims, and an escutcheon plate on a mortise lock is far larger than that. If you are replacing escutcheon trim and the door has paint shadow or extra fastener holes outside a 2-3/4 inch circle, order the S rose at 3-1/2 inch flat for more coverage, or specify escutcheon trim instead. Note that the drill resistant core route to Grade 1 security is tied to escutcheon trim, sectional trim needs the 1EK7K4 cylinder instead.
18) For an office or storeroom door in the same building, what mortise lock matches a BEST 45H classroom lock?
Function is the difference, not the lock body class. The Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option, and the NM8050 is a Grade 1 office/entrance mortise lockset with an auxiliary deadlatch; both are listed for 1-3/4 inch doors. The Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever. If the goal is one keying system across the building, the BEST 45H comes with SFIC prep less core, and the NM8080 lists an interchangeable core option.
19) What mortise lock should go on a restroom or dorm room instead of a BEST 45H classroom lock?
For a privacy opening, the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with a deadbolt for 1-3/4 inch doors, and the Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for doors 1-3/4 to 2 inch. For a dorm corridor door, the Sargent 7925 is a Grade 1 heavy duty dormitory exit function mortise lock with rose trim and a single cylinder deadbolt, which is the same rose-trim style as the 45H R configuration.
20) For a behavioral health unit, is a BEST 45H classroom lock the right choice or is there a ligature resistant option?
The 45H uses lever and knob trim including gull wing, curved, and solid tube styles, which are conventional operating trims. For anti-ligature openings, the TownSteel MRX-A-01 is a Grade 1 heavy duty passage mortise lockset with ligature resistant arch trim in satin stainless steel, and the MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel; both list 1-3/4 inch door thickness. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant in satin stainless steel. All three are passage function, so key control has to come from another opening in the plan.
21) For a healthcare corridor, which mortise lock offers an antimicrobial surface?
The BEST 45H is available in 626AM satin chrome and 630AM satin stainless steel with UltraShield antimicrobial protected coating, which inhibits growth of bacteria and other microbes on the hardware surface. Among the peers, the Marks USA 5PDN is a Grade 1 hospital passage push/pull paddleset in satin stainless steel and the TownSteel MRX-A-01 is satin stainless steel, but those are passage-function parts. A 45H in 626AM or 630AM keeps classroom key control on a patient-area door while giving the coated surface infection control asks for.
22) Is a mortise deadbolt an alternative to a BEST 45H, or does it do something different?
It does something different. The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset - the same backset as the BEST 45H - but a deadbolt alone has no latch and no lever, so it will not operate the door. The Kaba Ilco 185 Series is also a deadbolt function mortise lock. The BEST 45H is a complete lockset with a 3/4 inch throw stainless steel latchbolt plus a 1 inch throw deadbolt and lever or knob trim, so it handles both latching and locking on one prep.
23) Is there a keyless mortise lock that does not need wiring to the door, as an alternative to a BEST 45H?
The Dormakaba PowerPlex P2066 Series mortise lock and the E-Plex 2066 Series electronic pushbutton keyless mortise lock are both standalone keyless options. The E-Plex 5086 is a Grade 1 back to back pushbutton and card mortise lock for entry/egress. The BEST 45H stays purely mechanical with SFIC prep less core, so its access changes are made by rekeying the core rather than by managing codes or credentials.
24) Which comparable mortise locks carry a stated fire rating?
Among the peers, the Schlage Electronics LEMD-GRW ENGAGE Series wireless mortise lock lists a 3 hour fire rating and is Grade 1, and the LEBMB-ADD mobile-enabled mortise lock also lists 3 hours at Grade 2. The Falcon MA101 Grade 1 heavy duty mortise passage lock is listed as fire rated. The BEST 45H meets ANSI A156.13 Series 1000 Grade 1 for operation and strength, and its design and operation meet the intent of ANSI A117.1 section 404.2.6.
25) For a heavy traffic opening, how does a Codelocks CL2255 compare to a BEST 45H?
They are built to different duty levels. The Codelocks CL2255 is an electronic tubular mortise latch in the CL2000 Series with a medium duty rating, in brushed steel. The BEST 45H is heavy duty with a 0.095 inch cold rolled steel case, cover, and armored front, a roller bearing hub, and a solid one-piece stainless steel anti-friction latch. On a high cycle classroom or corridor door, that construction difference is the deciding factor.
26) Can staff tell at a glance whether a BEST 45H door is locked?
Yes, there is a visual indicator on the trim: an open padlock icon when unlocked and a closed red padlock when locked. On a corridor of classroom doors that matters during a drill, someone walking the hall can read door status without trying every lever. If you want a dedicated classroom security indicator lockset, 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 x 2-3/4 x 7/16 inches.
