BEST 45H0LT3J626VIN – Frequently Asked Questions

1) Will the BEST 45H privacy mortise lock fit a door thicker than 1-3/4 inches?
Standard 45H lock configuration is built for 1-3/4 inch doors. For anything thicker, BEST offers a thick door configuration covering doors up to 5 inches, but the thickness has to be specified at time of order. You cannot field-convert a standard lock to a thick door, so measure the leaf before you place the order.
2) Do I have to order the BEST 45H handed, and can handing be changed in the field?
Handing is a required selection: left hand, right hand, left hand reverse, or right hand reverse. That said, the latchbolt rotates 180 degrees to change hand without opening the case, and the cylinder retainer is non-handed, so a lock that arrives wrong-handed can still be corrected on the job.
3) Does the visual indicator on the BEST 45H privacy lock show occupancy from the corridor?
Yes. The indicator displays a padlock icon: open for unlocked, closed and painted red for locked. That is the point of the LT privacy configuration on restrooms, exam rooms, lactation rooms, and single-occupancy toilets, where staff and users need to read status without trying the lever.
4) Will the BEST 45H latch into my existing ANSI strike?
The latchbolt is solid stainless steel with a 3/4 inch throw and the deadbolt throws 1 inch, which are the standard mortise figures an ANSI 4-7/8 inch strike is cut for. The armored front wraps both latch and deadbolt and self-aligns to the door bevel during install, so minor bevel differences on an existing opening are not a problem.
5) Does the BEST 45H come with a cylinder or core?
No. It ships less cylinder and is a non-keyed privacy function, so no core or housing is included. If your facility keys BEST interchangeable cores, you order the core and housing separately to match your existing keyway and master key system.
6) Is the BEST 45H Grade 1, and does it meet accessibility requirements?
The 45H meets ANSI A156.13, Series 1000, Grade 1 Operation and Strength, with Grade 2 Security. Design and operation meet the intent of ANSI A117.1 section 404.2.6. To reach Grade 1 Security you need a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) with escutcheon trims, or the 1EK7K4 high security cylinder with sectional trims; the higher-security 47H Series carries Grade 1 for security outright.
7) How does the BEST 45H privacy mortise lock compare to other Grade 1 privacy mortise locks?
For a straight Grade 1 privacy mortise alternative, ZenSupply carries the Cal-Royal NM8440 privacy mortise lockset with deadbolt, listed Grade 1 for 1-3/4 inch doors, and the Hager 3840S 3800 Series privacy mortise lock on a 2-3/4 inch backset for 1-3/4 to 2 inch doors. The difference that usually decides it: the 45H carries the visual keyed indicator showing locked/unlocked status, which neither of those is listed with, and the 45H offers a thick-door configuration to 5 inches where the Hager tops out at 2 inches.
8) Which mortise lock should I use instead of the BEST 45H privacy if the room needs a keyed classroom function?
Privacy is a non-keyed function on the BEST 45H, so for a keyed classroom opening look at the Corbin Russwin ML2003, a Grade 1 mortise classroom lockset for 1-3/4 inch doors, or the Cal-Royal NM8070, a Grade 1 classroom mortise lockset also for 1-3/4 inch doors. If you want to keep the indicator feature in a classroom opening, the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset for 1-3/4 inch doors.
9) I need a privacy mortise lock with electronic access control instead of a mechanical thumbturn - what are the options?
The BEST 45H is a mechanical, non-electronic lock. For an electronic privacy mortise lock, the Schlage CO-100-MS standalone electronic mortise lock is Grade 1 heavy duty with privacy function and a keypad reader 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. Those bring credential management the 45H does not; the 45H gives you a purely mechanical device with no power or batteries to maintain.
10) What should I use instead of the BEST 45H on a behavioral health or psychiatric door?
The BEST 45H uses lever and knob trim, including gull wing, curved and solid tube levers and a round knob, which are not ligature resistant. For those openings TownSteel lists the MRX-L-01, a Grade 1 heavy duty anti-ligature lever mortise lockset with passage function for 1-3/4 inch doors, and the MRX-A-01, a satin stainless steel ligature resistant arch trim mortise lockset, also passage, for 1-3/4 inch doors. Marks USA also offers the 5PDN, a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel.
11) Will a Baldwin 6301 mortise lock body drop into the same prep as the BEST 45H?
No. The Baldwin 6301 entry/apartment mortise lock body is a 2-1/2 inch backset unit, listed for doors 1-3/4 inch and over, and the Baldwin 6310 entry/storeroom body is also 2-1/2 inch backset for doors 1-3/8 inch and over. The BEST 45H runs a 2-3/4 inch backset, so the cylinder and spindle hole locations in the door will not line up between the two.
12) Which finish should I specify for a hospital or food service door?
Two antimicrobial options are offered: 626AM satin chrome and 630AM satin stainless steel, both with the UltraShield coating that inhibits growth of bacteria and other microbes on the hardware surface. BEST recommends it for hospital and healthcare, elderly care, education, transportation, food service, and hospitality. If the coating is not needed, plain 626 and 630 are the usual commercial picks.
13) What trim and lever choices do I have to pick when ordering a 45H?
Three decisions beyond finish and handing. Trim style: H rose, R rose, or J wrought escutcheon. Lever style: 3 solid tube with return, 12 solid tube no return, 14 curved with return, 15 contour with angle return, 16 curved without return, 17 gull wing, or 4 round knob. Note the trim choice also affects the security path: drill resistant cores pair with escutcheon trims, the high security cylinder with sectional trims.
14) Is the 45H heavy duty enough for a high traffic restroom door?
It is built for it. Case, cover, and armored front are 0.095 inch cold rolled steel, zinc dichromate plated for corrosion resistance, with a roller bearing mechanism and the lever return spring located in the trim rather than the case, which is what fights lever droop on doors that get hit hundreds of times a day. The one-piece stainless anti-friction latch gives 50 percent more contact surface with the strike.
15) If I only need the door to latch without any locking, what is a simpler alternative to the BEST 45H privacy mortise lock?
A passage mortise lock removes the privacy locking and indicator entirely. The Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, for 1-3/4 inch doors. The Falcon MA101 is a Grade 1 heavy-duty mortise passage lock that is field reversible and fire rated. Hager also lists the 3810S passage mortise lock with rose and the 3810E with escutcheon, both on a 2-3/4 inch backset for doors 1-3/4 inch to 2-1/2 inch.
16) Is a Sargent 130KB thumbturn a substitute for the BEST 45H privacy mortise lock?
No. The Sargent 130KB is a standard duty mortise thumbturn in the 8200 Series, and the Sargent 130W is a mortise thumbturn with a round backplate in the 7800 Series. Those are trim pieces that mount to a mortise case, not complete locksets. The BEST 45H is a heavy duty mortise lock with case, latch, deadbolt, armored front and trim, supplied less cylinder. Order a thumbturn only when you are replacing trim on an existing case.
17) What is the equivalent of the BEST 45H if the opening needs a storeroom or office function on the same heavy duty mortise case?
Within mortise locks of the same class, 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 for 1-3/4 inch doors with an interchangeable core option. For office openings, the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with 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, on a 2-3/4 inch backset matching the BEST 45H.
18) Is a Schlage L0170 dummy trim the same thing as a BEST 45H privacy mortise lock?
No. The Schlage L0170 is a Grade 1 mortise non-keyed half dummy lever trim with a dummy function for 1-3/4 inch doors, meaning it has no latch or locking mechanism at all. The BEST 45H privacy is a working lockset with a stainless steel latchbolt at 3/4 inch throw, a deadbolt at 1 inch throw and a visual indicator. Emtek also lists dummy mortise entrance sets such as the 3102 Memphis and 3104 Hamilton, which are likewise inoperable trim.
19) For a healthcare corridor, how does the BEST 45H compare with the RFID and card-based mortise locksets?
The BEST 45H is mechanical and offers 626AM satin chrome and 630AM satin stainless steel finishes with UltraShield antimicrobial protected coating, which BEST recommends for hospital, elderly care and education use. If the facility needs credentialed access on the same opening, TownSteel lists the FME-2000 Series Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors, and Dormakaba lists the LX-I-M002 Saffire electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2. Those manage credentials; the 45H covers privacy with a mechanical indicator and antimicrobial finish.
20) I need a mortise deadbolt only, not a full privacy lockset like the BEST 45H - what fits?
The BEST 45H is a complete lockset with lever or knob trim, a latchbolt and a deadbolt in one 0.095 inch cold rolled steel case. If the opening only needs a bolt, the Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset, the same backset as the 45H, and the Kaba Ilco 185 Series is a non-handed mortise deadbolt.
21) Is the BEST 45H an electronic or access control lock?
No, it is purely mechanical. If the opening needs credentials or audit trail on a mortise prep, ZenSupply carries electronic mortise locks such as the Schlage CO-100 standalone keypad lock, which is also a privacy function Grade 1 mortise for 1-3/4 inch doors, and the Dormakaba E-Plex 2066 pushbutton keyless mortise lock.
