BEST 45H0LB3J626VIN – Frequently Asked Questions

1) Will the BEST 45H privacy mortise lock fit a 1-3/4 inch door?
Yes. The standard 45H mortise lock configuration is built for 1-3/4 inch doors, which is the usual commercial thickness. For anything thicker, BEST builds a thick-door configuration that covers doors up to 5 inches, and you have to state the actual door thickness when you place the order. Nothing ships as a field-adjustable thickness kit, so measure the leaf before ordering.
2) Will a BEST 45H mortise lock latch into the strike prep that's already in my frame?
Two numbers decide it. The 45H runs a 2-3/4 inch backset and a solid stainless latchbolt with a 3/4 inch throw, and the deadbolt throws 1 inch. If the existing frame is cut for a standard ANSI mortise strike at a 2-3/4 inch backset, the latch lines up. The armored front self-aligns to the door bevel during install, so a beveled edge isn't a separate order item. The faceplate is 8 x 1-1/4 x 1/16 inches, so an older short-face mortise pocket will need the edge routed out to 8 inches.
3) Does the BEST 45H privacy lock come handed, or do I pick left and right hand?
You pick a hand at order time (left, right, left hand reverse, right hand reverse), but the lock body itself is non-handed. The latch reverses by rotating 180 degrees without opening the case, and a four position hub toggle handles the rest of the configuration. Practically, that means if a door gets rehung the other way later, a locksmith changes the handing on site instead of buying another lock.
4) Does the BEST 45H privacy mortise lock need a key or a cylinder?
No key, no cylinder. The privacy version of the 45H is non-keyed and ships less cylinder, so there is no core to order and no keyway to match to the building's system. If you need the door keyed, you are looking at a different function in the 45H family, not this one.
5) What ANSI grade is the BEST 45H mortise lock, and does it meet accessibility requirements?
The 45H Series carries ANSI A156.13, Series 1000, Grade 1 Operation and Strength with Grade 2 Security. Its design and operation also meet the intent of ANSI A117.1 section 404.2.6 for accessibility. If a specification calls for Grade 1 Security rather than Grade 2, an escutcheon-trim 45H gets there only with a drill resistant core (1CD, 1CDP, 1CDF, or 1CDX); on sectional trims it takes the 1EK7K4 high security cylinder. The 47H Series is the one that holds Grade 1 for Operation, Strength, and Security out of the box.
6) What do I have to specify when ordering a BEST 45H indicator privacy lock?
Four decisions. Handing (left, right, left hand reverse, or right hand reverse). Trim style: H rose, R rose, or J wrought escutcheon. Lever or knob: 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. And finish. If the door is thicker than 1-3/4 inches, state the thickness too. No cylinder decision here, since privacy is non-keyed.
7) Is the Hager 3840S a direct alternative to a BEST 45H privacy mortise lock?
The Hager 3840S is a 3800 Series Grade 1 privacy mortise lock with a 2-3/4 inch backset, rated for doors 1-3/4 to 2 inches thick. That matches the BEST 45H privacy lock on backset and on privacy function, so the door prep intent is the same. The differences worth checking before ordering are trim and status display: the BEST 45H privacy lock is offered with escutcheon and rose trim and carries a visual indicator showing a padlock icon open for unlocked and closed and red for locked.
8) The opening needs to be locked and unlocked with a key from the outside, not a privacy turn. What replaces the BEST 45H?
That is storeroom or office duty, not privacy. The Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option, and the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with an auxiliary deadlatch for 1-3/4 inch doors. The BEST 45H privacy lock is non-keyed and ships less cylinder, so it will not take a key from the outside no matter which trim is chosen.
9) For a behavioral health or patient room where ligature resistance is required, what mortise lockset is used instead?
The TownSteel MRX-A-01 is a Grade 1 heavy duty ligature resistant arch trim mortise lockset in satin stainless steel, passage function, for 1-3/4 inch doors, and the MRX-L-01 is the stainless steel Grade 1 heavy duty anti-ligature lever version, also passage. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant, in satin stainless steel. The BEST 45H is offered with lever and knob trim styles and is not an anti-ligature design, so on a ligature-risk opening the TownSteel or Marks USA trims are the correct direction.
10) Will a Baldwin 6301 mortise lock body drop into a door prepped for a BEST 45H?
No. The Baldwin 6301 is a 2-1/2 inch backset entry/apartment mortise lock body, offered knob by knob or lever by lever, for doors 1-3/4 inches and over. The BEST 45H uses a 2-3/4 inch backset, so the lock case sits at a different distance from the door edge and the cross bores will not line up. Backset has to match the existing prep, or the door needs to be re-prepped.
11) What does the visual indicator on the BEST 45H actually show from the corridor side?
A padlock icon. Open padlock means unlocked, closed padlock painted red means locked. That is the whole reason to spec an indicator privacy lock over a plain privacy set: staff or a facility crew can read occupancy of a restroom, exam room, or lactation room from down the hall without trying the lever.
12) Which finish should I spec for a BEST 45H in a hospital or school?
Look at 626AM (satin chrome) or 630AM (satin stainless), both with the UltraShield antimicrobial protected coating that inhibits growth of bacteria and other microbes on the hardware surface. BEST recommends it where cleanliness is a priority, naming hospital and healthcare, elderly care, education, transportation, food service, and hospitality. Standard finishes run 605, 606, 611, 612, 613, 618, 619, 622, 625, 626, 629, 630, and 690. Two to know about before you standardize: 613 oxidized satin bronze is meant to wear to an antique look, and 690 dark bronze stays dark brown over time.
13) What's the difference between a BEST 45H indicator privacy lock and a plain privacy mortise lock like the Hager 3840S?
Function is the same job, the indicator is the difference. The Hager 3840S is a Grade 1 privacy/bed/bath mortise lock for doors 1-3/4 to 2 inches with a 2-3/4 inch backset, and the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors. Neither is listed with visual indication. Spec the 45H when someone needs to read locked or unlocked from outside the door; spec one of the others when a straightforward privacy set is all the opening needs.
14) Is the BEST 45H an electronic or access control lock?
It's fully mechanical. The 45H indicator privacy lock has no electronics, no power, no credential reader. If the job calls for card or keypad access on a mortise prep, that's a different animal: the Schlage CO-100 is a standalone electronic mortise lock with privacy function and a keypad reader, Grade 1, heavy duty, for 1-3/4 inch doors, and the Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock.
15) Does the BEST 45H come with a strike, and what else do I need to finish the door?
The lock body, the trim you selected, and the faceplate make up the order. Strike packages are specified separately, so confirm the strike with your order rather than assuming one is in the box. No cylinder is needed on the privacy function since it's non-keyed. The auxiliary bolt is stainless and non-handed, and four case cover screws (one at each corner) plus the interlocking armored front and cover at the latch hold the case together.
16) What should be used instead of a privacy mortise lock on a door that only needs latching and no locking at all?
For a hall, closet, or corridor door that never locks, a passage mortise lock is the correct part. The Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, the Falcon MA101 is a Grade 1 heavy-duty mortise passage lock with field reversible operation, and the Hager 3810S and 3810E are 3800 Series Grade 1 passage mortise locks with a 2-3/4 inch backset, offered with rose and with escutcheon respectively. The BEST 45H privacy lock adds a locking function and a visual indicator, which a passage opening has no use for.
17) Is the Schlage CO-100 privacy mortise lock an alternative to a mechanical indicator lock?
Both serve a privacy opening, but they are different classes of hardware. The Schlage CO-100 is a standalone electronic mortise lock in the CO Series, Grade 1, heavy duty, privacy/bed/bath function with a keypad reader, for 1-3/4 inch doors, so it needs codes managed and power at the lock. The BEST 45H is a non-electronic mechanical mortise lock with a visual indicator, so status is read off the trim and there is nothing to program or batter.
18) Can a Sargent 4874 mortise deadbolt be used in place of a privacy mortise lock?
They are not interchangeable. The Sargent 4874 is a double cylinder mortise deadbolt in the 4870 Series with a 2-3/4 inch backset, so it throws a bolt but carries no latch and no lever operation, and both sides need a key. The BEST 45H privacy lock is a non-keyed latching lockset with a visual indicator, so the door latches closed on its own and can be released from inside without a key. On an egress-sensitive room, the difference matters.
19) What mortise lock suits a dormitory or corridor door where the 45H privacy function is not enough?
The Sargent 7925 is a Grade 1 heavy duty dormitory exit function mortise lock in the 7900 Series with rose trim and a single cylinder deadbolt, which covers corridor and dormitory duty. The Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series for 1-3/4 inch doors if the opening is a classroom instead. Both are keyed applications; the BEST 45H privacy lock is non-keyed and intended for single-occupant privacy.
20) Is a Schlage L0170 half dummy trim a substitute for a BEST 45H escutcheon lock?
No. The Schlage L0170 is a half dummy trim, a Grade 1 non-keyed mortise lever for 1-3/4 inch doors, heavy duty, with no working latch behind it. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton, and 3106 Manhattan mortise entrance locksets are likewise dummy function. Those are for an inactive leaf or a pull-only door. The BEST 45H is a working mortise lock with a 3/4 inch throw latchbolt and a privacy indicator.
21) On a healthcare facility standardizing on antimicrobial hardware, which mortise locks carry an antimicrobial finish?
The BEST 45H is offered in 626AM satin chrome and 630AM satin stainless steel with UltraShield antimicrobial protected coating, which inhibits growth of bacteria and other microbes on the hardware surface. Among the Grade 1 mortise peers built for the same environments, the Marks USA 5PDN hospital passage push/pull paddleset and the TownSteel MRX-A-01 are specified in satin stainless steel, and the TownSteel is Grade 1 heavy duty for 1-3/4 inch doors. For a facility that wants the coating itself on privacy openings, the 45H AM finishes are the ones to write into the spec.
22) Which mortise lock should be specified when the privacy door also needs to be released or monitored by an access control system?
The Command Access ML190 is a heavy-duty motorized mortise lock with field selectable fail safe and fail secure operation on 24VDC, 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, running on 12 or 24VDC for 1-3/4 inch doors. Both require power and wiring to the door. The BEST 45H is a non-electronic mechanical lock, so it gives indication at the door but no signal back to a head end.
23) Do the levers on a BEST 45H droop over time in a high traffic building?
BEST puts a lever return spring mechanism in the trim specifically to resist lever droop, and the hub runs on roller bearings for wear-resistant operation. On the latching side, the one-piece stainless anti-friction latchbolt is oil-impregnated and has 50 percent more surface contact with the strike, with a curve profile intended for cycle life. That's the combination that matters on a school corridor or an apartment common area restroom where the lever gets hit thousands of times a month.
