BEST 45H7INL3J626VIN – Frequently Asked Questions

1) Will the BEST 45H mortise lock fit a 1-3/4 inch door, and what about thicker doors?
The standard 45H lock configuration is built for 1-3/4 inch doors, which is the usual commercial thickness. For anything thicker, BEST makes a thick door configuration that goes up to 5 inches, but the thickness has to be specified on the order. There is no field adjustment for it, so measure the leaf before you order.
2) What does the intruder function on the BEST 45H indicator lock actually do during a lockdown?
The intruder function (INL) is the lockdown lock for classrooms and offices: the door is secured from inside without anyone stepping into the corridor. The keyed visual indicator on the 45H reads the state at a glance, an open padlock icon when unlocked and a closed padlock with red paint when locked, so staff or responders know the door's status from the hallway side without pulling on the lever. It uses a single cylinder with an SFIC housing, supplied less core.
3) Does the BEST 45H come with a core, or do I have to supply my own?
It ships as an SFIC housing less core, so the small format interchangeable core is a separate line item. That is normally what you want on a keyed facility: you pin and key the core into the existing system yourself rather than accepting a factory keying. Budget a core, or a construction core, for every lock on the order.
4) Do I need to specify handing for a BEST 45H mortise lock?
Handing is required on the order, and the four choices are left hand, right hand, left hand reverse, and right hand reverse. That said, the lock body itself is non-handed: the latch is reversible and rotates 180 degrees without opening the case, and there is a four position hub toggle, so a lock that shows up backwards can be corrected on the bench rather than returned.
5) Will the BEST 45H latch into the strike that is already in my frame?
The 45H runs a 2-3/4 inch backset with a 3/4 inch latchbolt throw and a 1 inch deadbolt throw, which are the standard commercial mortise numbers, so it lines up with an existing mortise prep and ANSI strike in most cases. The faceplate is 8 x 1-1/4 x 1/16 inches and self-adjusts to the door bevel during install. Check that your existing strike box has depth for the 1 inch deadbolt if you are coming off a latch-only lock.
6) What ANSI grade is the BEST 45H, and how do I get it to Grade 1 security?
The 45H meets ANSI A156.13 Series 1000, Grade 1 Operation and Strength, Grade 2 Security as supplied. To reach Grade 1 Security you have to add hardware: a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) with escutcheon trims, or a 1EK7K4 high security cylinder with sectional trims. If your spec calls out Grade 1 Security outright, the 47H Series carries Grade 1 for Operational, Strength and Security without the added core. The design also meets the intent of ANSI A117.1 section 404.2.6.
7) What is the closest cross-brand equivalent to a BEST 45H intruder-function mortise lock with a visual indicator?
The TownSteel FME-4000 Series is the nearest peer in the set: it is an electronic intruder classroom mortise lockset with RFID technology, Grade 1, heavy duty, for 1-3/4 inch doors. The difference to weigh is the credential: the BEST 45H intruder lock is a mechanical, keyed single-cylinder mortise lock with an SFIC prep less core, while the FME-4000 reads RFID credentials. If the specification calls for intruder function on a key system rather than a card system, the 45H is the mechanical route; if the facility is standardizing on cards, the FME-4000 carries the same intruder intent electronically.
8) Is a classroom-function mortise lock the same thing as an intruder-function mortise lock?
No. Classroom function peers such as the Cal-Royal NM8070 Grade 1 classroom mortise lockset with auxiliary deadlatch and the Corbin Russwin ML2003 Grade 1 mortise classroom lockset, both for 1-3/4 inch doors, are keyed from the corridor side only - the outside key locks and unlocks the outside lever, and there is no way to secure the door from inside the room. The BEST 45H intruder function lock is built for the opposite need, letting the room side secure the opening, with a visual indicator that shows the state. If a lockdown procedure requires an occupant to lock the door without stepping into the corridor, a classroom-function lock is not a substitute.
9) Which mortise lock do I use if the door needs to be locked and unlocked from an access control system?
For remote control of the opening, the Command Access ML190 is a heavy-duty motorized mortise lock with field selectable fail safe or fail secure 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. Both need power transfer to the door. The BEST 45H is a mechanical lock with no electronics, so it works with keys and its own indicator rather than with a credential reader or a door controller.
10) Can a keypad or credential mortise lock replace a keyed indicator mortise lock on a classroom door?
It changes how the door is operated, not just the brand. The Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes in classroom function for doors 1-5/8 inch to 1-7/8 inch thick, the Alarm Lock DL2700CR is a Grade 1 Trilogy T2 classroom electronic mortise lock in the same thickness range with a weatherproof design, and the TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors. All three require code or credential management. The BEST 45H is mechanical and keyed single cylinder with an SFIC prep, and its indicator shows lock state at the door with no batteries or programming involved. Note also that the Alarm Lock door thickness range stops at 1-7/8 inch, while the 45H is standard at 1-3/4 inch with a thick door build to 5 inch.
11) What mortise lockset is used for a behavioral health or ligature-resistant opening?
For anti-ligature openings the set carries the TownSteel MRX-L-01, a stainless steel Grade 1 heavy duty anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, the MRX-A-01 with satin stainless ligature resistant arch trim in passage function, 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. All three are passage function. The BEST 45H uses conventional lever or knob trim and is keyed, so it fits secured staff and corridor doors rather than patient rooms where the trim itself has to be ligature resistant. Where the 45H does suit a healthcare opening, it offers 626AM satin chrome and 630AM satin stainless finishes with UltraShield antimicrobial coating.
12) Which mortise lock matches a residential-style entry door rather than a commercial opening?
The Baldwin 6301 entry/apartment mortise lock body comes as knob by knob or, as the 6301LS, lever by lever, both on a 2-1/2 inch backset for doors 1-3/4 inch and over, and the Baldwin 6310 entry/storeroom body is also a 2-1/2 inch backset for doors 1-3/8 inch and over. The BEST 45H is a commercial heavy duty lock on a 2-3/4 inch backset, so the two are not interchangeable in an existing door prep - the backset dimension alone differs. Check which backset the door is already machined for before choosing.
13) What trim and lever options do I have to pick on a BEST 45H order?
Three decisions besides finish and handing. Trim is H rose, R rose, or J wrought escutcheon. Lever style runs 3 solid tube with return, 12 solid tube with no return, 14 curved with return, 15 contour with angle return, 16 curved without return, 17 gull wing, or 4 round knob. The trim choice also drives the security path: escutcheon trims take the drill resistant core route to Grade 1 Security, sectional trims take the high security cylinder. Lever return springs sit in the trim, which is what keeps levers from drooping over time.
14) Is there an antimicrobial version of the BEST 45H for a hospital or school?
Two finishes carry the UltraShield antimicrobial coating: 626AM satin chrome and 630AM satin stainless steel. The coating inhibits growth of bacteria and other microbes on the hardware surface, and BEST points it at hospital and elderly care, education, transportation, food service and hospitality work. If cleanliness drives the spec, order the AM suffix rather than plain 626 or 630, since the two look alike on a submittal but only one has the coating.
15) What is the difference between a mechanical indicator lock like the BEST 45H and an electronic intruder classroom lock?
The 45H is purely mechanical, no power, no batteries, no network. It locks down from inside with a key and shows status on a visual indicator. If you need credentials, audit trail or remote lockdown across a campus, that is a different product: the TownSteel FME-4000 Series is a Grade 1 electronic intruder classroom mortise lockset with RFID for 1-3/4 inch doors, and the Alarm Lock DL3500CR is a Grade 1 electronic classroom mortise lock with 300 user codes for 1-5/8 to 1-7/8 inch doors. Mechanical wins on maintenance and on doors you cannot power; electronic wins when you need to change access without rekeying.
16) What else could I buy instead of the BEST 45H if I want a mechanical classroom security indicator mortise lock?
The closest mechanical peer is the Marks USA LA318GJ classroom security indicator mortise lockset, Grade 1, for 1-3/4 inch doors, supplied with an ANSI strike and a steel escutcheon measuring 8-1/2 x 2-3/4 x 7/16 inches. The real difference is the cylinder: the 45H is prepped for a small format interchangeable core, so it drops into a BEST SFIC keying system. If your facility is not on SFIC, that advantage disappears and the Marks is worth a look. If you only need storeroom function without the indicator, the Corbin Russwin ML2003 and Cal-Royal NM8080 are Grade 1 mortise options for 1-3/4 inch doors.
17) Can I standardize a whole building on the 45H and use different functions on different doors?
Yes, and that is the usual way it is spec'd. The 45H is one series with a common case, backset and faceplate across functions, so the door prep is identical whether an opening gets intruder function, storeroom, classroom or office. That means one template, one strike, one core system across the building, and a swap of function later does not mean re-routing the door. Keep the finish and lever style consistent across the order and the openings match visually as well as mechanically.
18) The door is not a lockdown opening and only needs to latch - what mortise lock should be used instead of a 45H indicator lock?
For a non-keyed opening, the Hager 3810S is a Grade 1 passage mortise lock with a rose and a 2-3/4 inch backset for doors 1-3/4 inch to 2-1/2 inch thick, and the Hager 3810E is the same passage lock with an escutcheon. Schlage's PM010 is a Grade 1 passage latch mortise lock, non-keyed, for 1-3/4 inch doors, and the Falcon MA101 is a Grade 1 heavy-duty mortise passage lock that is field reversible and fire rated. The BEST 45H indicator lock is keyed with a single cylinder and an SFIC prep, which a passage opening has no use for; all four passage peers share the mortise case format, so the door prep concept is the same.
19) What mortise lock should be specified for a privacy restroom or bedroom door rather than a keyed indicator lock?
Privacy peers in mortise format include the Cal-Royal NM8440 Grade 1 privacy mortise lockset with deadbolt and the Hager 3840S Grade 1 privacy mortise lock with a 2-3/4 inch backset, listed for doors 1-3/4 inch to 2 inch thick; both are built for 1-3/4 inch and similar doors. These lock from the occupied side and are not keyed on a master key system. The BEST 45H is keyed with a single cylinder and prepped for an SFIC core, which is what a secured corridor, office, or classroom opening needs and a restroom generally does not.
20) Which of these mortise locks looks like a substitute for a 45H but is only trim or a deadbolt, not a complete lockset?
Several mortise-named items in the category are not locksets at all. The Schlage L0170 is half dummy trim, a Grade 1 mortise non-keyed lever with no latching mechanism, and the Emtek 3102 Memphis, 3104 Hamilton, 3106 Manhattan, and 3019 Brisbane are dummy function mortise entrance locksets. The Sargent 130KB and 130W are mortise thumbturns, and the Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, which throws a bolt but does not latch. The BEST 45H is a complete heavy duty keyed mortise lock with both a latchbolt and a deadbolt plus lever or knob trim, so none of those items replaces it on a working door.
21) What is the difference between a BEST 45H and a Sargent 7925 for a dormitory corridor door?
The Sargent 7925 is a heavy duty Grade 1 dormitory exit function mortise lock from the 7900 Series with rose trim and a single cylinder deadbolt. The BEST 45H is also heavy duty and keyed single cylinder, with an SFIC housing prepped less core, and it carries a visual indicator plus intruder function. Trim choice differs too: the 45H can be ordered with H rose, R rose, or J wrought escutcheon, so a rose-trim look is available either way. The deciding factors are whether the room side needs to secure the door with the state shown on the indicator, and whether the keying is a small format interchangeable core system.
22) Does an RFID or mobile credential mortise lock carry the same grade as a BEST 45H?
Grade varies by product, so it is worth checking rather than assuming. The Dormakaba Saffire LX-I-M002 electronic RFID mortise lockset with BLE mobile access is BHMA Grade 2, and the Schlage LEBMB-ADD mobile-enabled mortise lock with push button and LED is Grade 2 with a 3 hour fire rating for 1-3/4 inch doors. The Schlage LEMD-GRW ENGAGE wireless mortise lock with a 125kHz proximity reader is Grade 1 with a 3 hour fire rating, and the Dormakaba E-Plex E5086 back to back pushbutton and card lock is Grade 1. The BEST 45H meets ANSI A156.13 Series 1000 Grade 1 Operation and Strength with Grade 2 Security, and reaches Grade 1 Security when a drill resistant core is used with escutcheon trim or the 1EK7K4 high security cylinder with sectional trim.
23) Is a medium duty electronic mortise latch an acceptable substitute on a high traffic commercial door?
The Codelocks CL2255 is an electronic tubular mortise latch in a brushed steel finish, rated medium duty in the CL2000 Series. The BEST 45H is a heavy duty commercial mortise lock with a 0.095 inch cold rolled steel case, cover, and armored front and a solid stainless steel anti-friction latch, meeting ANSI A156.13 Series 1000 Grade 1 Operation and Strength. On a door cycling heavily - a school corridor, a hospital wing, a multi-tenant entry - the duty rating is the distinction to weigh, and the CL2255 is a medium duty latch rather than a heavy duty lockset.
24) Which mortise lock suits an ornamental iron door with a thin stile?
The Marks USA 21AC and 22AC are entrance double cylinder ornamental iron mortise locks with a round knob, both listed for 1 inch door thickness. The BEST 45H is built around 1-3/4 inch doors as standard with a thick door configuration to 5 inch, and uses a 2-3/4 inch backset, so it does not fit a 1 inch iron gate or screen stile. For the ornamental iron application the 21AC or 22AC is the correct family; the 45H belongs on a commercial wood or hollow metal leaf.
25) If the facility is standardizing on a touchscreen keypad mortise lock, what is the peer and how does it differ from a keyed 45H?
The Accentra NTM623-NR is a Grade 1 nexTouch Generation 3 mortise lock with a capacitive touchscreen keypad, no deadbolt, with cylinder override. Two differences matter for standardization: it has no deadbolt, while the BEST 45H includes a 1 inch throw stainless steel deadbolt alongside its latchbolt, and the NTM623-NR is credential driven with a key only as override, while the 45H is keyed single cylinder prepped for an SFIC core throughout. If the key system is already small format interchangeable core across the building, the 45H stays inside it.
26) I need to match the finish on the rest of the doors in my building. What finishes does the BEST 45H come in?
Fourteen finishes: 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 flat black, 625 bright chrome, 626 satin chrome, 626AM, 630 satin stainless, 630AM, and 690 dark bronze. Two behave differently over time on purpose: 613 is meant to wear to an antique appearance, and 690 stays a dark brown. If you are matching existing openings exactly, avoid those two unless the rest of the building is already living finish.
27) Is the BEST 45H heavy enough for a high traffic entrance or corridor door?
It is built for heavy duty commercial traffic. Case, cover and armored front are 0.095 inch cold rolled steel, zinc dichromate plated against corrosion. The latchbolt is solid one-piece stainless with 50 percent more surface contact at the strike and an oil-impregnated anti-friction face, and the hub runs on roller bearings. The armored front wraps both the latch and the deadbolt for lateral strength. On a door that gets thousands of cycles a week, the anti-friction latch and bearing hub are what keep it from dragging.
28) Which mortise lock should be used for an office or entrance door with a keyed cylinder and no indicator?
The Cal-Royal NM8050 is a heavy duty Grade 1 office/entrance mortise lockset with an auxiliary deadlatch for 1-3/4 inch doors. For a non-keyed office door, the Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon on a 2-3/4 inch backset for doors 1-3/4 inch to 2-1/2 inch. The BEST 45H matches the 2-3/4 inch backset of the 3850E and is keyed single cylinder with an SFIC prep, and it adds the visual indicator and intruder function that an ordinary office door does not call for.
29) What mortise deadbolt options exist if the opening already has a latch and only needs bolting?
The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset from the 4870 Series, and the Kaba Ilco 185 Series is a non-handed mortise deadbolt sold in a single pack. The Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad for doors 1-5/8 inch to 1-7/8 inch thick. None of these latches the door. The BEST 45H integrates both a latchbolt and a 1 inch throw deadbolt in one heavy duty case, so it handles latching and bolting in a single mortise pocket on a 2-3/4 inch backset.
30) Which mortise lock handles a door that needs power at the lock without running wire?
The Dormakaba PowerPlex P2066 Series mortise lock is the self-powered route in this group, and the Schlage LEMD-GRW is an ENGAGE Series wireless mortise lock with a 125kHz proximity reader, Grade 1, 3 hour fire rated. The Alarm Lock DL1300NW is a Trilogy Networx wireless electronic mortise lock with a keypad. The BEST 45H is not electronic at all, so no power, wire, or battery enters the equation - the trade is that access rights are managed by keys and cores rather than by software, with the indicator giving the status at the door.
31) What replaces a 45H mortise lock on an opening that has an exit device instead of a lockset?
An opening fitted with a panic device takes trim, not a lockset: the Falcon MESC600DT is a dummy escutcheon lever trim for M9900 Series exit devices, fire rated and dummy function. That is pull trim on a door where the exit device does the latching. The BEST 45H is a keyed heavy duty mortise lock with its own latchbolt and deadbolt and cannot serve on a door whose latching is handled by an exit device.
