BEST 45H0LB3J626 – Frequently Asked Questions

1) Will the BEST 45H privacy mortise lock fit a door thicker than 1-3/4 inches?
The standard 45H configuration is built for 1-3/4 inch doors. BEST also builds a thick door configuration for doors up to 5 inches, but the thickness has to be specified at time of order, so it isn't something you adapt in the field. Measure the leaf before ordering.
2) Does the 45H privacy mortise lock need a key or cylinder?
No. The LB privacy function is non-keyed, operated by a thumbturn inside with the locking toggle showing locked or unlocked. The 45H case does come with an SFIC prep less core as the standard cylinder arrangement, so a small format interchangeable core can be added where the trim calls for it, but nothing is required for the privacy function to work.
3) Do I have to order the BEST 45H privacy lock handed?
No. The latch is reversible and rotates 180 degrees for a handing change without opening the case, and the hub uses a four position toggle. The auxiliary bolt is non-handed as well. That makes it practical to stock one lock for both hands across a building.
4) Will the 45H latch engage my existing ANSI strike?
The latchbolt is solid one-piece stainless with a 3/4 inch throw, and the privacy function also carries a stainless deadbolt with a 1 inch throw thrown by the inside turn. A standard ANSI mortise strike with a deadbolt cutout will take both. If your current frame only has a latch-only strike prep, you need the full strike package for the deadbolt.
5) Is the BEST 45H Grade 1, and what does it take to get Grade 1 security?
The 45H meets ANSI A156.13 Series 1000, Grade 1 Operation and Strength, with Grade 2 Security as built. To reach Grade 1 Security with escutcheon trim, a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) must be used; with sectional trims it takes the 1EK7K4 high security cylinder. If your spec demands Grade 1 across operation, strength and security out of the box, the 47H Series is the one that carries all three.
6) What is a direct alternative to the BEST 45H privacy mortise lock from another manufacturer?
The Cal-Royal NM8440 is a heavy duty Grade 1 privacy mortise lockset with a deadbolt, and the Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset like the 45H. The BEST 45H privacy lock uses a 2-3/4 inch backset and is supplied with SFIC prep less core, so if you are keying a building on Best small format cores the 45H keeps that program intact while the Cal-Royal and Hager bodies are their own platforms.
7) The door does not need to lock at all - what should I use instead of a privacy mortise lock?
For a door that only needs to latch, a passage function mortise lock is the right part: the Falcon MA101 is a Grade 1 heavy-duty mortise passage lock with field reversible operation, the Hager 3810E is a Grade 1 passage mortise lock with escutcheon trim and a 2-3/4 inch backset, and the Schlage PM010 is a Grade 1 passage latch mortise lock. The BEST 45H with LB privacy function adds the inside locking toggle and thumbturn operation those passage locks do not have.
8) I need the same 45H body but the door has to be keyed - what do I order instead?
The 45H in the LB privacy configuration is non-keyed, so for a keyed opening look at a keyed mortise function instead: the Accentra 8805FL is a Grade 1 storeroom mortise lock, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option, the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with auxiliary deadlatch, and the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset.
9) For a behavioral health or patient room, is the 45H privacy lock the right choice or is there a ligature resistant option?
For anti-ligature openings, TownSteel makes the MRX-L-01 stainless steel Grade 1 heavy duty anti-ligature lever mortise lockset and the MRX-A-01 ligature resistant arch trim mortise lockset, both passage function for 1-3/4 inch doors, and the Marks USA 5PDN is a Grade 1 hospital passage push/pull paddleset that is ligature resistant and ADA compliant. The BEST 45H offers 626AM and 630AM UltraShield antimicrobial finishes for healthcare cleanliness but uses conventional lever and knob trim.
10) A classroom needs to be securable from inside - is the 45H privacy function acceptable?
Classroom security openings are usually specified with a dedicated classroom function instead. The Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset with ANSI strike and steel escutcheon for 1-3/4 inch doors, the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch, and the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset. The BEST 45H LB is a privacy/bed/bath function and is non-keyed.
11) What do I have to specify when ordering a BEST 45H privacy mortise lock?
Four things decide the part: trim style (J wrought escutcheon, M forged escutcheon, or N forged escutcheon with concealed cylinder), lever or knob design (3 solid tube with return, 12 solid tube no return, 4 round knob, contour with angle return, curved with or without return, or gull wing), finish, and door thickness if the leaf is over 1-3/4 inches.
12) Which BEST 45H finish should I use in a hospital or elderly care facility?
Two antimicrobial options are offered: 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 for healthcare, elderly care, education, transportation, food service and hospitality. Twelve standard finishes are also available, from 605 bright brass through 690 dark bronze.
13) What are the alternatives to the BEST 45H if I need a privacy mortise lock from another brand?
Two direct peers we carry: the Hager 3840S 3800 Series Grade 1 privacy mortise lock with a 2-3/4 inch backset, listed for 1-3/4 to 2 inch doors, and the Cal-Royal NM8440 Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors. If you want privacy function with electronic credentialing instead of a thumbturn, the Schlage CO-100 standalone electronic mortise lock is a Grade 1 privacy unit with a keypad reader for 1-3/4 inch doors. The 45H is the one to pick when you are standardizing on BEST SFIC across the building.
14) Is escutcheon trim or sectional rose trim the right choice on a BEST 45H?
Escutcheon trim covers the mortise pocket with one long plate, which is what you want if the door face is scarred from a previous lock, and on the 45H it is also the trim that reaches Grade 1 Security when paired with a drill resistant core. Sectional trim needs the 1EK7K4 high security cylinder to get there instead. Three escutcheon options are offered: J wrought, M forged, and N forged with a concealed cylinder for a clean face where no key is used.
15) Does the BEST 45H privacy lock meet accessibility requirements for lever operation?
BEST states the design and operation of the 45H mortise lock meets the intent of ANSI A117.1 section 404.2.6. If you are specifying for an accessible opening, choose one of the lever designs rather than the 4 round knob, since a knob is not an accessible operating device.
16) Is there an electronic privacy mortise lock if I want keypad credentials instead of a mechanical thumbturn?
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 covering privacy, office and apartment functions at Grade 2 with a 3 hour fire rating. The BEST 45H is a mechanical, non-electronic lock, so it needs no power or credential management.
17) Will a Baldwin 6301 mortise body drop into a door prepped for the BEST 45H?
No. The Baldwin 6301 entry/apartment mortise lock body uses a 2-1/2 inch backset, while the BEST 45H is a 2-3/4 inch backset, so the trim and cylinder centerlines will not line up in an existing 45H mortise pocket. The Baldwin is also an entrance/apartment function rather than privacy.
18) What is the difference between the BEST 45H escutcheon privacy lock and the Hager 3840S privacy mortise lock?
Both are 2-3/4 inch backset privacy mortise locks. The Hager 3840S is listed for doors 1-3/4 to 2 inches thick. The BEST 45H standard configuration is built for 1-3/4 inch doors with a thick door configuration available up to 5 inches when specified at order, and it is offered in wrought, forged, and forged concealed cylinder escutcheon trims across fourteen finishes including two UltraShield antimicrobial options.
19) Can I just add a mortise thumbturn to an existing lock instead of buying the 45H privacy lock?
A thumbturn such as the Sargent 130KB standard mortise thumbturn for the 8200 Series or the 130W with round backplate for the 7800 Series is a trim component for a lock body already prepped for it, not a lock in itself. The BEST 45H LB is a complete heavy duty mortise lock with privacy function, escutcheon trim, and an 8 inch stainless faceplate, so it is the part to order when the door has no privacy-capable body in it.
20) What should I use for a dormitory corridor door rather than the 45H privacy lock?
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 usual pick for a corridor or dorm room door needing outside key control. The BEST 45H LB is a non-keyed privacy function intended for bed and bath type openings, and it is supplied with escutcheon trim rather than rose.
21) How do the 613 and 690 finishes on the BEST 45H hold up over time?
613 oxidized satin bronze, oil rubbed, is designed to wear over time and develop an antique appearance, so it will not stay uniform across a run of doors. 690 dark bronze coated stays a dark brown appearance over time. If you need a consistent match across a building for years, a plated and clear coated finish like 626 satin chrome or 630 satin stainless is the steadier choice.
22) Will the levers droop on a BEST 45H in a high traffic corridor?
The lever return spring sits in the trim rather than the case, which is the arrangement BEST uses to guard against lever droop, and the hub runs on roller bearings for wear resistance. Case construction is 0.095 inch cold rolled steel, zinc dichromate plated, with four cover screws at the corners and an interlocking armored front. It is catalogued as heavy duty commercial hardware.
23) I only need a dummy or inactive side on the second leaf - what pairs with a 45H opening?
For an inactive leaf you want a dummy trim rather than a working lock body. The Schlage L0170 is a Grade 1 mortise non-keyed half dummy lever trim for 1-3/4 inch doors, and Emtek offers dummy mortise entrance locksets in the Brisbane 3019, Memphis 3102, Hamilton 3104 and Manhattan 3106 designs. The BEST 45H carries a working privacy latch and deadbolt, so it is not the part for a fixed inactive leaf.
