BEST 45H0LB15H626 – Frequently Asked Questions

1) Will the BEST 45H privacy mortise lock fit a 1-3/4 inch door?
Yes. The standard 45H lock configuration is built for 1-3/4 inch doors, which is the usual commercial thickness. For anything thicker, BEST offers a thick door configuration covering doors up to 5 inches, but you have to specify the actual door thickness at the time of order. There is no field adjustment for that, so measure the leaf before you write the order.
2) Do I have to order the BEST 45H mortise lock handed?
No. The latchbolt is field reversible, rotating 180 degrees to change hand without opening the case, and the stainless auxiliary bolt is non-handed. That means one part number covers both hands on the shelf, which is worth something if you are stocking spares across a building.
3) How does the privacy function on the BEST 45H work, and does it take a key?
It's a non-keyed bed and bath function. The inside thumbturn throws the 1 inch deadbolt to lock the door, and there is visual indication of locked and unlocked state, with optional padlock icon indicators. No cylinder and no key are part of the privacy configuration. If you need a keyed override or a keyed function on the same opening, that is a different function in the series.
4) What ANSI grade is the BEST 45H mortise lock?
ANSI A156.13, Series 1000, Grade 1 for operation and strength, Grade 2 for security. The design also meets the intent of ANSI A117.1 section 404.2.6. If a spec calls for Grade 1 security on a keyed opening in this family, BEST's 47H Series is the one rated Grade 1 for operation, strength and security.
5) What do I need to specify when ordering a BEST 45H privacy mortise lock?
Four things decide the part: the finish, the lever style, the rose style, and the door thickness if it is over 1-3/4 inches. Finishes run from 605 bright brass through 690 statuary dark bronze, including 613 oil rubbed bronze which is meant to wear to an antique look and 690 which stays dark brown. Lever choices include 3 solid tube with return, 12 solid tube with no return, 4 round knob, curved with or without return, contour with angle return, and gull wing. Roses are H flat 2-3/4 inch, R concave 2-3/4 inch, or S flat 3-1/2 inch.
6) Will the BEST 45H latch into the strike that is already in my frame?
The latchbolt throws 3/4 inch and the deadbolt throws 1 inch, both on a 2-3/4 inch backset, which is the standard commercial mortise layout. If the existing lock is a 2-3/4 inch backset ANSI mortise with a strike cut for a 1 inch deadbolt, the throws line up. A 2-1/2 inch backset body, like Baldwin's 6301 mortise lock body, will not drop into the same prep.
7) I need a mortise lock for a restroom door that does not need to lock at all - what should I use instead of the 45H privacy?
If the opening only needs latching with free operation from both sides, a passage function is the correct choice rather than the BEST 45H privacy. The Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, the Hager 3810S is a Grade 1 passage mortise lock with rose trim and a 2-3/4 inch backset, and the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation. The BEST 45H differs in that its privacy function adds a locking thumbturn with a 1 inch deadbolt throw.
8) The 45H privacy is non-keyed - what mortise lock do I order for the same door if it has to take a key?
The BEST 45H with privacy function is listed as non-keyed, so a keyed opening needs a different function. Comparable keyed mortise locks include the Accentra 8805FL Grade 1 storeroom lock from the 8800 Series, the Cal-Royal NM8080 Grade 1 storeroom mortise lockset with interchangeable core option for 1-3/4 inch doors, the Cal-Royal NM8050 Grade 1 office/entrance lockset with auxiliary deadlatch, and the Corbin Russwin ML2003 Grade 1 mortise classroom lockset.
9) For a patient room or behavioral health door, is there a mortise lock better suited than the BEST 45H?
The BEST 45H offers UltraShield antimicrobial finishes in 626AM and 630AM for healthcare cleanliness, but it uses standard lever and rose trim. Where ligature resistance is the governing requirement, the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, the TownSteel MRX-A-01 is the same passage function with satin stainless ligature resistant arch trim, and the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant. Those three are passage function rather than privacy.
10) Will a Baldwin 6301 mortise lock body drop into the same door prep as the BEST 45H?
No. The Baldwin 6301 entry/apartment mortise lock body uses a 2-1/2 inch backset, while the BEST 45H is built on a 2-3/4 inch backset, so the cylinder and trim holes will not line up on the same door. The Baldwin 6301 is also an entrance/apartment function for doors 1-3/4 inch and over, versus the privacy function of the 45H. Plan on a new prep or a lock that matches the existing 2-3/4 inch dimension.
11) For a dorm room door, is the BEST 45H privacy the right function or should I look at something else?
The BEST 45H privacy function locks from the inside only and is non-keyed, which suits sleeping rooms and baths. Where a dorm room needs keyed entry plus an inside deadbolt, the Sargent 7925 is a Grade 1 heavy duty dormitory exit function mortise lock with rose trim and a single cylinder deadbolt from the 7900 Series. Both use rose trim; the difference is keyed dormitory operation versus non-keyed privacy.
12) Which BEST 45H finish should I use in a hospital or elder care facility?
BEST offers two UltraShield antimicrobial options on the 45H, 626AM satin chrome and 630AM satin stainless, with a coating that inhibits growth of bacteria and other microbes on the hardware surface. BEST recommends them for hospital and healthcare, elderly care, education, transportation, food service and hospitality. If cleanliness is not the driver, the standard 626 and 630 are the same appearance without the coating.
13) What else could I use instead of the BEST 45H for a Grade 1 privacy mortise lock?
Two straightforward alternatives: the Hager 3840S, a Grade 1 privacy mortise lock on the same 2-3/4 inch backset with a 1-3/4 to 2 inch door thickness range, and the Cal-Royal NM8440, a Grade 1 heavy duty privacy mortise lockset with deadbolt for 1-3/4 inch doors. If you want access control on a privacy opening rather than a mechanical thumbturn, the Schlage CO-100 standalone electronic mortise lock is a Grade 1 privacy function with a keypad reader for 1-3/4 inch doors.
14) How does the BEST 45H hold up on a high traffic door, and will the levers droop?
The case, cover and armored front are 0.095 inch cold rolled steel, zinc dichromate plated for corrosion resistance, with four corner screws holding case integrity. The lever return spring sits in the trim rather than the case, which is what protects against lever droop over time, and the hub runs on roller bearings. The latch is solid one piece stainless, oil impregnated, with roughly 50 percent more contact surface with the strike than a comparable latch.
15) My door is prepped for a cylindrical lock, not a mortise pocket - what is the equivalent?
The BEST 45H is a mortise lock and needs a mortise pocket in the door edge. For a bored cylindrical prep, the Schlage PC10 is a Grade 1 non-keyed passage cylindrical lock with rose for 1-3/4 inch doors. Note that it is passage function, so it does not provide the thumbturn locking of the 45H privacy configuration.
16) I only need matching inactive trim on the pair of doors - do I still order a 45H?
No, an inactive leaf takes dummy trim rather than a working lock. The Schlage L0170 is a Grade 1 non-keyed half dummy mortise lever trim, heavy duty, for 1-3/4 inch doors. The Emtek 3102 Memphis and 3104 Hamilton are mortise entrance locksets in dummy function if a decorative ornamental look is wanted. The BEST 45H by contrast is a working privacy lock with a 3/4 inch throw latch and 1 inch deadbolt.
17) I want escutcheon trim rather than the rose trim on the BEST 45H - what are my options?
The BEST 45H rose trim configuration offers roses in 2-3/4 inch flat, 2-3/4 inch concave and 3-1/2 inch flat. For a full escutcheon plate look, the Hager 3810E is a Grade 1 passage mortise lock with escutcheon on a 2-3/4 inch backset and the Hager 3850E is the office function with lever and escutcheon; the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset with a steel escutcheon measuring 8-1/2 inch H x 2-3/4 inch W x 7/16 inch. Those are different lock functions, so confirm the function before substituting.
18) If I need access control on the same opening, what mortise lock replaces the BEST 45H?
The BEST 45H is a mechanical non-electronic lock. For credentialed or networked access on a mortise prep, 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 TownSteel FME-2000 Series is a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors, and 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.
19) The BEST 45H comes with SFIC prep - which comparable mortise locks also take an interchangeable core?
The BEST 45H ships with SFIC prep less core, though the privacy function itself is non-keyed. Among comparable mortise locks, the Cal-Royal NM8080 Grade 1 storeroom lockset is offered with an interchangeable core option for 1-3/4 inch doors. If you are standardizing a facility on one core system, pair the non-keyed 45H privacy openings with a keyed storeroom or classroom lock that accepts your core.
