BEST 45H0L3J622VIB – 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. If your opening is thicker, BEST makes a thick door configuration for doors up to 5 inches, but that has to be specified at the time of order, so measure the leaf before you order. The lock takes a 2-3/4 inch backset and an 8 x 1-1/4 x 1/16 inch faceplate, and the lock face self-adjusts to the door bevel during install.
2) Do I have to specify handing on a BEST 45H mortise lock?
You pick a hand on the order (left hand, right hand, left hand reverse, right hand reverse), but the lock body itself is non-handed. The latchbolt reverses by rotating it 180 degrees without opening the case, and there is a four position hub toggle, so if the hand on the drawing turns out wrong in the field you can change it at the door instead of sending the lock back. The auxiliary bolt is non-handed stainless as well.
3) What does the double visual indicator on the BEST 45H privacy lock actually show?
Two indicators, one on each side of the door, showing an open padlock icon when the room is unlocked and a closed padlock icon painted red when it is locked. That is the point of the L privacy function in a restroom, exam room, or single-occupancy space: staff and the next person in line can read occupancy from the corridor without trying the lever.
4) Does the BEST 45H come with a cylinder or core?
No. The 45H privacy lock ships less cylinder and is a non-keyed function, so no core or housing is included. That is normal for a privacy lock, and it is also how BEST handles keyed 45H functions, since the small format interchangeable core is ordered to your facility's keyway and keying separately. There is a cylinder security screw in the design that prevents cylinder removal until the interchangeable core comes out first.
5) Is the BEST 45H mortise lock Grade 1?
It carries ANSI A156.13 Series 1000, Grade 1 Operation and Strength with Grade 2 Security. Where a spec calls for Grade 1 Security on a mortise lock, BEST's answer is the 47H series, which is rated Grade 1 for operational, strength and security. On the 45H, Grade 1 Security can be reached by using a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) with escutcheon trim, or a 1EK7K4 high security cylinder with sectional trim. The design also meets the intent of ANSI A117.1 section 404.2.6 for accessibility.
6) I need a privacy mortise lock but not the indicator. What else does ZenSupply carry?
The straight mechanical alternative is the Cal-Royal NM8440, a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors, or the Hager 3840S, a Grade 1 privacy mortise lock on a 2-3/4 inch backset for doors 1-3/4 to 2 inches. Both are privacy/bed/bath function without the double visual indicator the 45H carries. If you want the occupancy readout but electronically managed, the Schlage CO-100-MS-40-KP is a standalone Grade 1 electronic mortise lock with privacy function and a keypad reader for 1-3/4 inch doors. The 45H itself is purely mechanical.
7) Can I use a BEST 45H privacy lock on a classroom or office door?
No. The L privacy function locks and unlocks from inside the room and is non-keyed, so there is no outside key control at all. For a classroom you want a keyed classroom mortise function such as the Corbin Russwin ML2003 or the Cal-Royal NM8070, both Grade 1 for 1-3/4 inch doors, or the Marks USA LA318GJ if you need a classroom security indicator lockset. For an office door, the Cal-Royal NM8050 entrance/office or the Hager 3850E office function are the right family. The 45H series itself offers other functions, including the C public entrance function, so staying within BEST is an option.
8) What is the closest Grade 1 privacy mortise lock to the BEST 45H if I need a deadbolt on the bathroom door?
The Cal-Royal NM8440 is a Grade 1 privacy/bed/bath mortise lockset with a deadbolt, prepped for 1-3/4 inch doors. The BEST 45H privacy mortise lock is also rated ANSI A156.13 Series 1000 Grade 1 Operation and Strength with a 2-3/4 inch backset and a standard configuration for 1-3/4 inch doors, and it carries a double visual indicator that shows a padlock icon open when unlocked and a closed red padlock icon when locked. If the occupied/vacant indication is what the job calls for, stay with the 45H; if the deadbolt throw is the deciding feature, the NM8440 covers it.
9) Is the Hager 3840S a direct swap for a BEST 45H privacy mortise lock?
They land in the same place on the door: the Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for doors 1-3/4 to 2 inches thick, and the BEST 45H privacy mortise lock also uses a 2-3/4 inch backset with a standard configuration for 1-3/4 inch doors. The difference that decides it is the indication - the 45H carries a double visual indicator reading locked and unlocked from both sides, which the 3840S is a plain privacy function without. BEST also builds the 45H to accept an interchangeable core with a cylinder security screw, and offers thick-door configurations up to 5 inches.
10) For a behavioral health or psychiatric unit, is the 45H the right mortise lock?
For those openings the ligature-resistant families are the ones written into the spec. The TownSteel MRX-L-01 is a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, the 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, ADA compliant, in satin stainless steel. The BEST 45H is a conventional lever or knob mortise lock - its lever styles run from solid tube to gull wing and round knob - and it meets the intent of ANSI A117.1 section 404.2.6 for ADA, but it is not built as an anti-ligature trim.
11) What lever and trim choices do I have to pick when ordering a BEST 45H?
Three decisions on the order form. Trim: H rose, R rose, or J wrought escutcheon. Lever: 12 solid tube with no return, 3 solid tube with return, 14 curved with return, 16 curved without return, 15 contour with angle return, or 17 gull wing. There is also a 4 round knob. Trim choice is not just looks on this series, since BEST's Grade 1 Security path differs for escutcheon versus sectional trim. The trim mechanism is self aligning, which is what keeps the two sides square during install.
12) Is a mortise lock like the BEST 45H worth it over a cylindrical lock for a restroom?
A mortise lock puts the entire mechanism inside a pocket routed into the door edge, so the case and cover take the abuse rather than a through-bored chassis. On the 45H that case, cover and armored front are 0.095 inch cold rolled steel with zinc dichromate plating, running on a roller bearing hub. The trade is prep: mortising a door is more work than boring one, so on an existing door with only a 2-1/8 inch cross bore, a cylindrical lock such as the Schlage PC10 Grade 1 passage is the less invasive route. New doors specified for heavy traffic are where the mortise earns its keep.
13) Can I standardize my building on BEST 45H locks across different door functions?
Yes, and that is the usual reason facilities buy the series. The 45H is one case, one 2-3/4 inch backset, one 8 x 1-1/4 x 1/16 inch faceplate and one door prep across functions, so the privacy restroom doors and the keyed openings share the same mortise pocket and strike prep. Change the function or the trim and the hole in the door does not change. Finishes and lever designs carry across the series as well, so an office corridor and a restroom can match.
14) For a healthcare facility that wants antimicrobial hardware, how does the 45H compare with the other stainless mortise options?
The BEST 45H is offered in 626AM satin chrome and 630AM satin stainless steel with the UltraShield antimicrobial protected coating, which inhibits growth of bacteria and other microbes on the hardware surface and is aimed at hospital, elderly care, education, transportation, food-service and hospitality work. Among the comparable mortise locks, the Marks USA 5PDN is a Grade 1 hospital passage push/pull paddleset in satin stainless steel and the TownSteel MRX-A-01 is a satin stainless ligature-resistant passage lockset - both are stainless, both are passage function rather than privacy. If the requirement is a coated privacy lock with occupancy indication, the 45H in 626AM or 630AM is the one that meets it.
15) The door does not need to lock at all - what should I use instead of the 45H privacy lock?
Drop to a passage function. 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 that is field reversible and fire rated, and the Hager 3810S and 3810E are Grade 1 passage mortise locks with a 2-3/4 inch backset, the 3810S with rose trim and the 3810E with escutcheon. The BEST 45H privacy version adds the locking function and the double visual indicator that a passage latch does not have, so on a corridor or closet door that never locks, the passage lock is the matching part.
16) Can I use a Sargent 4874 mortise deadbolt in place of a 45H privacy mortise lock?
No - the Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset, which means it throws a bolt but carries no latch and no lever, so the door has no operating trim and both sides require a key. The BEST 45H privacy mortise lock combines a 3/4 inch throw latchbolt operated by the lever with the privacy locking function and the double visual indicator on a matching 2-3/4 inch backset. A 4874 is an addition to a door that already has a latch, not a replacement for the 45H.
17) I need privacy indication on a patient room or dorm room but the facility wants electronic access - what replaces the 45H?
The Schlage CO-100 is a standalone electronic mortise lock in privacy function with a keypad reader, Grade 1, heavy duty, for 1-3/4 inch doors. The Schlage LE Series LEBMB-ADD is a mobile-enabled mortise lock with a push button and LED covering privacy, office and apartment functions, Grade 2, with a 3 hour fire rating on 1-3/4 inch doors. The BEST 45H is a mechanical lock with no electronics, so it needs no power, no batteries and no credential management - the trade is that status is read off the mechanical double visual indicator instead of a reader and audit trail.
18) We standardize on Grade 1 mortise locks across the building - what covers the keyed openings alongside a 45H privacy lock?
The BEST 45H privacy version is non-keyed and ships less cylinder. For the keyed doors in the same corridor, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option on 1-3/4 inch doors, the NM8070 is the Grade 1 classroom version and the NM8050 is the Grade 1 office/entrance version with auxiliary deadlatch, all on 1-3/4 inch doors. The Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, and the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series for 1-3/4 inch doors. Matching the 45H's trim and finish across a mixed set is the other half of the decision - it runs 14 finishes from 605 bright brass through 630AM satin stainless antimicrobial.
19) Is a Baldwin 6301 mortise lock body an alternative to the BEST 45H?
They are prepped differently, so no. The Baldwin 6301 is an entry/apartment mortise lock body on a 2-1/2 inch backset for doors 1-3/4 inch and over, offered knob by knob or as the 6301LS lever by lever, and the 6310 entry/storeroom body is also 2-1/2 inch backset for doors 1-3/8 inch and over. The BEST 45H uses a 2-3/4 inch backset, so the mortise pocket and cross-bore centerline do not line up between the two - swapping either way means re-prepping the door. Function differs as well: the Baldwin bodies are entry and storeroom, the 45H here is the non-keyed privacy function with a double visual indicator.
20) Which mortise locks give the same dormitory or corridor behavior if the 45H privacy function is too restrictive?
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 - the occupant throws the deadbolt from inside and always has free egress, with key access from the corridor. The BEST 45H privacy configuration is non-keyed and shows state with the double visual indicator, which suits a restroom or single-occupancy room where no one needs to key in from outside. On a dorm or apartment corridor door where staff must be able to enter, the 7925 is the function that fits.
21) Which mortise locks fit a door thinner than 1-3/4 inches if the 45H standard configuration does not?
The Alarm Lock Trilogy electronic mortise locks cover a 1-5/8 to 1-7/8 inch range - the DL2700CR classroom function weatherproof lock, the DL3500CR Grade 1 classroom lock with 300 user codes, and the DL4500DB Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad. The Baldwin 6310 entry/storeroom mortise body covers 1-3/8 inch and over on a 2-1/2 inch backset. The BEST 45H standard configuration is built for 1-3/4 inch doors, with thick door configurations available up to 5 inches when the thickness is specified on the order.
22) Is an Emtek 3102 Memphis mortise entrance lockset a substitute for a BEST 45H?
It is not - the Emtek 3102 Memphis, 3104 Hamilton, 3106 Manhattan and 3019 Brisbane brass mortise entrance locksets in the comparable set are all dummy function, meaning fixed trim with no latch and no operating mechanism, used on an inactive leaf. The BEST 45H is a working heavy duty commercial mortise lock with a privacy function, a 3/4 inch throw stainless latchbolt and a 1 inch throw deadbolt, ANSI A156.13 Series 1000 Grade 1 Operation and Strength.
