BEST 45H0L3J626VIN – Frequently Asked Questions

1) Will the BEST 45H privacy mortise lock fit a 1-3/4 inch door, and what about thicker doors?
Standard 45H lock configuration is built for 1-3/4 inch doors, which is the usual commercial thickness. For anything heavier, a thick door configuration covers doors up to 5 inches, but the thickness has to be specified at time of order. There is no field adjustment, so measure the leaf before you order.
2) What does the visual indicator on a BEST 45H privacy lock actually show?
The indicator shows a padlock icon: open padlock for unlocked, closed red padlock for locked. It reads from the corridor side, so staff can see occupancy without trying the lever. That is the reason this version gets specified for restrooms, exam rooms, and single-occupancy spaces where the L privacy function is in use.
3) Does the BEST 45H privacy mortise lock come with a cylinder or a core?
It ships less cylinder. The privacy function is non-keyed at the lever, and the small format interchangeable core housing and core are not included, so if the opening needs a keyed override you order the housing and core separately in your existing BEST keyway.
4) Do I have to specify handing when ordering a BEST 45H mortise lock?
Hand is a required selection: left hand, right hand, left hand reverse, or right hand reverse. That said, the latchbolt is reversible through 180 degrees without opening the case, and the four-position hub toggle lets each hub be set always locked, always unlocked, or locked by key, so a handing change in the field does not mean a new lock body.
5) Is the BEST 45H lock Grade 1, and does it meet Grade 1 security?
45H carries ANSI A156.13, Series 1000, Grade 1 Operation and Strength, but Grade 2 Security as furnished. To reach Grade 1 Security you have to add a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) with escutcheon trim, or a 1EK7K4 high security cylinder with sectional trim. If the spec on your drawing calls for Grade 1 across the board including security, the 47H Series is rated Grade 1 for Operational, Strength and Security out of the box.
6) What is the difference between a privacy mortise lock like the BEST 45H L and a classroom or storeroom function?
Privacy locks the lever from inside the room for single-occupancy spaces, restrooms and exam rooms, with the indicator telling anyone outside whether it is in use. It is not a keyed security function. If you need the door secured from outside at all times with free egress, that is a storeroom function such as the Cal-Royal NM8080 or the Accentra 8805FL. If a teacher needs to lock the corridor side during a lockdown, that is a classroom function like the Corbin Russwin ML2003 or the Cal-Royal NM8070. Ordering privacy where the spec wanted storeroom is the most common mistake on this family.
7) What else can I use if I need a Grade 1 privacy mortise lock but not the BEST keyway?
Two straightforward alternatives. The Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors. The Hager 3840S is a Grade 1 privacy mortise lock on a 2-3/4 inch backset, rated for doors 1-3/4 to 2 inches, so it matches the BEST backset if your existing prep is already cut that way. Neither one is listed with a visual occupancy indicator, so if the indicator is the reason you were looking at the 45H, it is not a like-for-like swap.
8) What mortise lock gives a keyed classroom function instead of privacy?
For a classroom opening, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors, the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with an auxiliary deadlatch for 1-3/4 inch doors, and 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 Marks LA318GJ is the closest match if the indicator is the reason you were looking at the BEST 45H, which is a privacy function and non-keyed lock.
9) What is the closest cross-brand equivalent to a BEST 45H privacy mortise lock?
The Hager 3840S is a Grade 1 privacy/bed/bath mortise lock with a 2-3/4 inch backset, which matches the 2-3/4 inch backset the BEST 45H privacy mortise lock uses. The Cal-Royal NM8440 is a second Grade 1 privacy mortise lockset, listed with a deadbolt and a 1-3/4 inch door thickness. The BEST 45H carries a visual indicator that shows an open padlock icon for unlocked and a closed red padlock for locked, and its standard configuration is for 1-3/4 inch doors with a thick door configuration available up to 5 inch when specified at order.
10) Which mortise lock should I use if the door does not need to lock at all?
For an opening with no locking requirement, the Hager 3810E is a Grade 1 passage mortise lock with escutcheon trim and a 2-3/4 inch backset, and the Hager 3810S is the same passage function with rose trim; both list a 1-3/4 inch to 2-1/2 inch door thickness range. The Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, and the Falcon MA101 is a Grade 1 heavy duty passage/hall/closet mortise lock that is field reversible. The BEST 45H is a privacy function lock with a visual indicator, so it holds the door secured from the inside rather than latching free both ways.
11) Which mortise lock fits a door thinner than 1-3/4 inch?
The Alarm Lock DL2700CR classroom, DL3500CR classroom and DL4500 deadbolt models all list a 1-5/8 inch to 1-7/8 inch door thickness range, and the Baldwin 6310 entry/storeroom knob by knob with a 2-1/2 inch backset lists 1-3/8 inch and over. The Marks USA 21AC and 22AC ornamental iron mortise locks list a 1 inch door thickness for narrow iron stiles. The BEST 45H standard configuration is built for 1-3/4 inch doors, with a thick door configuration up to 5 inch when the thickness is specified at order.
12) I need a 2-3/4 inch backset mortise lock. Which comparable locks match that and which do not?
The BEST 45H uses a 2-3/4 inch backset. Among comparables, the Hager 3810E and 3810S passage locks, the Hager 3840S privacy lock, the Hager 3850E office lock and the Sargent 4874 double cylinder mortise deadbolt are all listed at a 2-3/4 inch backset. The Baldwin 6301 entry/apartment and 6310 entry/storeroom bodies, in both knob by knob and lever by lever versions, use a 2-1/2 inch backset, so the mortise pocket location in the door differs and they are not a drop-in for a 2-3/4 inch prep.
13) Which BEST 45H finish should I use in a hospital or clinic?
For healthcare, the antimicrobial finishes are 626AM (satin chrome) and 630AM (satin stainless), both with the UltraShield coating that inhibits bacteria and microbe growth on the hardware surface. BEST recommends them anywhere cleanliness is a priority, including elderly care, education, food service, transportation and hospitality. The standard non-AM finishes run from 605 bright brass through 690 dark bronze, fourteen options in total.
14) What lever and trim choices do I have to pick for a BEST 45H mortise lock?
Three decisions on the order form. Trim style is H rose, R rose, or J wrought escutcheon. Lever style is 12 solid tube no return, 14 curved with return, 15 contour with angle return, 16 curved without return, 17 gull wing, 3 solid tube with return, or 4 round knob. Then the finish. Note that the trim choice ties back to the security rating: escutcheon trim takes a drill resistant core to reach Grade 1 Security, sectional trim takes the 1EK7K4 cylinder.
15) Does the BEST 45H mortise lock need power or wiring?
No power, no wiring. It is a fully mechanical heavy duty mortise lock, so there is no transformer, no power transfer hinge and no access control head end to coordinate. If the project actually calls for credential access on a mortise prep, that is a different animal, for example the Schlage CO-100 standalone electronic mortise lock in privacy function with a keypad reader, or the TownSteel FME-2000 with RFID.
16) Is the BEST 45H mortise lock ADA compliant for accessible openings?
The design and operation of the BEST mortise lock meets the intent of ANSI A117.1 section 404.2.6, which is the accessible door hardware operation requirement. Practically, that means specifying one of the lever trims rather than the 4 round knob, since a knob is not an accessible operating device.
17) Can I standardize the whole building on BEST 45H and just change the function per door?
Yes, and that is how the 45H family is normally specified. Same case, same 2-3/4 inch backset, same 8 inch faceplate and same trim across the openings, with the function letter changing per door: L privacy for restrooms and single-occupancy rooms, C public entrance for the main doors. Picking one finish and one lever style across the fourteen finishes and seven lever options keeps the door prep and the spare parts common building-wide.
18) Which mortise lock should I order for a storeroom or entrance door instead of a privacy lock?
The Accentra 8805FL is a Grade 1 storeroom mortise lock from the 8800 Series with an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. For an office or entrance opening, the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with an auxiliary deadlatch for 1-3/4 inch doors, and the Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon, non-keyed, 2-3/4 inch backset, for 1-3/4 inch to 2-1/2 inch doors. The BEST 45H covers privacy openings and ships less cylinder.
19) Is there an electronic privacy mortise lock alternative to a mechanical indicator lock?
The Schlage CO-100-MS-40-KP is a standalone electronic mortise lock with privacy function and a keypad reader, Grade 1, heavy duty, for 1-3/4 inch doors. The Schlage Electronics LEBMB-ADD is a mobile-enabled mortise lock with push button and LED covering privacy, office and apartment functions, Grade 2, with a 3 hour fire rating for 1-3/4 inch doors. The BEST 45H reaches the same privacy result mechanically and is listed as non-electronic, so the status is read from the visual padlock indicator rather than from credentials or an audit trail.
20) Do any of the Sargent mortise thumbturns or deadbolts replace a privacy mortise lock?
No. The Sargent 130KB and 130W are mortise thumbturns, standard duty, and the Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset; the Kaba Ilco 185 Series is a deadbolt function mortise lock. A thumbturn is the operating trim and a deadbolt secures the door without a latch or lever, so none of them carry the latching lever function. The BEST 45H is a complete heavy duty privacy mortise lock with a 3/4 inch throw stainless latchbolt and a 1 inch throw deadbolt, and takes lever styles including curved with return and gull wing.
21) What mortise lock do I use for a behavioral health or ligature resistant opening?
For anti-ligature applications the TownSteel MRX-A-01 is a Grade 1 heavy duty passage function mortise lockset in satin stainless steel with ligature resistant arch trim for 1-3/4 inch doors, and the MRX-L-01 is the Grade 1 heavy duty anti-ligature lever version, also passage function for 1-3/4 inch doors. 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; the BEST 45H is a privacy lock and offers 626AM and 630AM antimicrobial finishes for healthcare openings.
22) Which mortise lock should I use if the opening needs access control or a credential reader?
For credentialed openings, the TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors and the FME-4000 adds electronic intruder classroom function with RFID. The Dormakaba LX-I-M002 Saffire is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2, the Dormakaba E5086 E-Plex is a Grade 1 entry/egress pushbutton and card back to back mortise lock, and the Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating. The BEST 45H is a mechanical privacy lock with no electronics.
23) What do I order if the mortise lock needs to be electrically controlled from an access system?
The Command Access ML190 Series is a heavy duty motorized mortise lock with field selectable electrically locked or electrically unlocked operation on 24VDC, listed with 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, 12/24VDC, for 1-3/4 inch doors. The Alarm Lock DL1300NW Trilogy Networx is a wireless electronic mortise lock with keypad for Adams Rite deadlatches. The BEST 45H is a mechanical privacy lock and is not electrified, so it holds status with a visual indicator rather than reporting to a panel.
24) Which mortise lock covers a dormitory or corridor opening where the occupant locks from inside but the door is also keyed?
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, listed as corridor/dormitory function. The Baldwin 6301 entry/apartment mortise lock body, available knob by knob or lever by lever with a 2-1/2 inch backset, is an entrance/apartment function for doors 1-3/4 inch and over. The BEST 45H is a privacy function lock supplied less cylinder, so it secures the room from the inside without keyed corridor control.
25) How durable is the BEST 45H lock body for a high-traffic door?
Case, cover and armored front are 0.095 inch cold rolled steel with zinc dichromate plating for corrosion protection. The latchbolt is solid one-piece stainless steel, oil impregnated, with 50 percent more surface contact against the strike, and the hub runs on roller bearings to cut wear on both the lock and the strike. That is the build for corridors, schools and multi-tenant buildings where the door gets cycled all day.
26) Is the Kaba Ilco BR glass door bottom rail lock an alternative to a mortise lockset?
No. The Kaba Ilco BR Series is a glass door bottom rail lock, which mounts into the rail of an all-glass door rather than into a door edge pocket. The BEST 45H is a heavy duty mortise lock for commercial swing doors, using a 2-3/4 inch backset and an 8 inch H x 1-1/4 inch W x 1/16 inch T faceplate in the door edge. For a glass storefront rail the BR Series is the correct family; for a hollow metal or wood door prepped for a mortise case, the 45H is.
27) If I want keyless code entry on a mortise prep without wiring, what are the options?
The Dormakaba E-Plex 2066 Series is an electronic pushbutton keyless mortise lock listed for wide stile applications, and the Dormakaba PowerPlex P2066 Series is a mortise lock from the PowerPlex 2000 Series. The Accentra NTM623-NR nexTouch Generation 3 is a Grade 1 mortise lock with a capacitive touchscreen keypad, no deadbolt, with cylinder override. The BEST 45H takes a different approach: it is a mechanical privacy lock with a keyed visual indicator showing locked and unlocked status, supplied less cylinder.
