BEST 45H7H3J626 – Frequently Asked Questions

1) What does the hotel function on the BEST 45H mortise lock actually do?
Hotel function is the shutout setup used on guest room doors. The 45H hotel lock is keyed single cylinder, and it carries both a 3/4 inch throw stainless latchbolt and a 1 inch throw stainless deadbolt, so the guest can throw the deadbolt from inside and shut out the housekeeping and master keys. Visual indicators on the trim show locked and unlocked states, with optional padlock icon indicators. It ships prepped for a small format interchangeable core but without the core, so the core and keying are ordered separately to match your existing hotel system.
2) Will the BEST 45H mortise lock fit a 1-3/4 inch door, and what about thicker doors?
Standard 45H configuration is built for 1-3/4 inch doors, which is the usual commercial thickness. For anything heavier, BEST makes a thick door configuration good up to 5 inches, but the thickness has to be specified at time of order, so it is not something you adjust in the field. Backset is 2-3/4 inches and the faceplate is 8 inches H x 1-1/4 inches W x 1/16 inch T, with the lock face self-adjusting to the door bevel during installation.
3) Do I have to specify handing when I order a BEST 45H mortise lock?
No handing to call out. The 45H case is non-handed, and the latchbolt is reversible, rotating 180 degrees without opening the case. There is also a four position hub toggle. Practical effect for a property manager stocking spares: one lock covers left and right hand openings, so a single part number covers a whole floor of guest rooms.
4) Will the BEST 45H latch into the ANSI strike already in my frame?
The 45H uses a 2-3/4 inch backset with a 3/4 inch latchbolt throw and a 1 inch deadbolt throw, which is standard mortise geometry, and the armored front surrounds both bolts. If the existing prep is a standard mortise pocket with a 2-3/4 inch backset and an 8 inch faceplate cutout, the lock drops into it. Two things to check on the old strike: it has to have a deadbolt cavity, since the hotel function throws a 1 inch bolt, and the anti-friction latch on the 45H has 50 percent more surface contact with the strike than a conventional latch, so the strike lip needs to be in good shape.
5) Is the BEST 45H hotel lock Grade 1, and does it meet Grade 1 security?
The 45H meets ANSI A156.13, Series 1000, Grade 1 for Operation and Strength, with a Grade 2 Security rating as standard. To reach Grade 1 Security with escutcheon trim, a drill resistant core is required (1CD, 1CDP, 1CDF, or 1CDX). If a spec calls for Grade 1 across the board including security, BEST's 47H Series is the one that carries A156.13 Series 1000 Grade 1 for Operational, Strength, and Security. The design also meets the intent of ANSI A117.1 section 404.2.6.
6) Does a BEST 45H mortise lock come with the cylinder core?
No core in the box. The 45H is supplied with small format interchangeable core prep, less core, so you order the core and keying separately and key it into whatever BEST system the property already runs. That is the point of SFIC on a hotel: you rekey a room by pulling and swapping the core with a control key instead of pulling the lock. A cylinder security screw prevents the cylinder being removed without first taking the core out, and solid machined cylinder rings with a wavy washer resist wrenching.
7) Is a Baldwin 6301 mortise lock body interchangeable with a BEST 45H?
The backsets differ, so the door prep does not carry over. The Baldwin 6301 is an entry/apartment function mortise lock body with a 2-1/2 inch backset for doors 1-3/4 inches and over, offered knob by knob or lever by lever as the 6301LS. The BEST 45H runs a 2-3/4 inch backset. The Baldwin 6310 entry/storeroom body is also 2-1/2 inch backset, for doors 1-3/8 inches and over. Treat these as a separate prep, not a drop-in.
8) What is the closest heavy duty Grade 1 mortise lock to the BEST 45H if I need a storeroom function instead of hotel function?
The BEST 45H is a hotel function mortise lock, so a guest room opening is its home. For a storeroom opening, where the outside lever stays locked and the key retracts the latch, the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset offered with an interchangeable core option for doors 1-3/4 inches thick. The interchangeable core option on the NM8080 is the one to look at if you are already keying the 45H, which is prepped SFIC less core.
9) Can I use a Sargent 7925 in place of a BEST 45H hotel lock on a dormitory door?
They are different openings. 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, so the deadbolt is thrown from inside and the door is always egressable. The BEST 45H is a hotel function lock supplied with escutcheon trim and keyed as a single cylinder. If your spec calls for corridor/dormitory function with rose trim, the 7925 is the match; if it calls for hotel function with escutcheon, the 45H is.
10) What should I use instead of a BEST 45H if the guest room door needs a card reader or keypad rather than a key?
The 45H is a mechanical mortise lock with no electronic function. For credentialed access on the same mortise prep, the Dormakaba Saffire LX-I-M002 is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2, and the Dormakaba E-Plex E5086 is a Grade 1 back-to-back electronic pushbutton and card lock with entry/egress function in the E-Plex 5X86 Series. For a Grade 1 wireless option with a 125kHz proximity reader and a 3 hour fire rating, the Schlage LEMD-GRW is an ENGAGE Series mortise lock with Greenwich trim, right hand.
11) Which mortise lock should I specify instead of the BEST 45H for a behavioral health or patient room where ligature resistance is required?
The 45H uses conventional lever and knob trim, including gull wing, curved and solid tube levers. Where the trim itself must not present an anchor point, the TownSteel MRX-A-01 is a Grade 1 heavy duty ligature resistant arch trim mortise lockset in satin stainless steel with passage function for 1-3/4 inch doors, and the MRX-L-01 is a Grade 1 heavy duty anti-ligature lever version. For a push/pull opening, the Marks USA 5PDN is a Grade 1 hospital passage mortise paddleset that is ligature resistant and ADA compliant in satin stainless steel. All three are passage function, so plan any locking at a different point in the suite.
12) Will an Alarm Lock Trilogy DL3500CR fit the same door as a BEST 45H?
Check the door thickness before you swap. The BEST 45H standard configuration is built for 1-3/4 inch doors, with thick door configurations available up to 5 inches when specified at order. The Alarm Lock DL3500CR is a Grade 1 classroom function electronic mortise lock rated for doors 1-5/8 to 1-7/8 inches, as are the DL2700CR classroom lock and the DL4500 electronic mortise deadbolt. So the Trilogy units cover the standard 1-3/4 inch door but not the thick door openings the 45H can be ordered for.
13) I need the mortise lock to release electrically from an access control panel. What replaces the BEST 45H?
The 45H is mechanical, so an electrified body is the change. The Command Access ML190 is a heavy duty motorized mortise lock with field selectable EL/EU operation on 24VDC in storeroom function. The Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit, at 12/24VDC for 1-3/4 inch doors, in corridor function. Field selectable EL/EU on the ML190 lets you set fail secure or fail safe at install; the Schlage unit is ordered as electrically unlocked with the RX switch built in.
14) What is the difference between escutcheon trim and sectional or rose trim on a BEST 45H?
Escutcheon trim is the long single plate that covers the lever and the cylinder together, which is what the 45H hotel configuration uses. Three escutcheon styles are offered: J wrought, M forged, and N forged with a concealed cylinder. The N style hides the cylinder behind the escutcheon, which is the one to pick when you want the keyway out of sight on a guest room door. Trim choice also affects the security rating path: with escutcheon trims a drill resistant core gets you to Grade 1 Security, while sectional trims require the 1EK7K4 high security cylinder instead.
15) Which lever styles and finishes can I get on the BEST 45H, and can I match the other doors in the building?
Seven trim designs are offered on the 45H: 12 solid tube no return, 3 solid tube with return, 4 round knob, contour with angle return, curved with return, curved without return, and gull wing. Finishes run 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 oil rubbed satin bronze, 618 bright nickel, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, 630 satin stainless, 690 statuary dark bronze, plus 626AM and 630AM antimicrobial. Note that 613 is meant to wear to an antique look over time, so it will not stay uniform against newer hardware, and 690 darkens to a brown appearance.
16) I need a mortise lock for a classroom or storeroom door, not a hotel room. What should I buy instead?
Hotel function is a shutout function for guest rooms, so it is the wrong pick for a classroom or a storeroom. For classroom, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors, and Cal-Royal's NM8070 is a Grade 1 classroom mortise lockset for the same thickness. For storeroom, look at the Cal-Royal NM8080, which offers an interchangeable core option, or the Accentra 8805FL Grade 1 storeroom mortise lock with Arcadia lever. Office and entrance is covered by the Cal-Royal NM8050.
17) Should I put a mechanical hotel mortise lock on guest rooms or go with an electronic RFID lock?
The 45H is a mechanical, non-electronic lock keyed to an interchangeable core, which means no batteries, no reader, and rekeying is a core swap. That is the right call when the property is already on a BEST key system or when you do not want to maintain credentials. If you want card or mobile credentials at the guest room door, the electronic mortise options are a different animal: TownSteel's FME-2000 is a Grade 1 heavy duty mortise lockset with RFID for 1-3/4 inch doors, Dormakaba's Saffire LX-I-M002 is an RFID mortise lockset with BLE mobile access at BHMA Grade 2, and Dormakaba's E-Plex 2066 is a pushbutton keyless mortise lock.
18) Is there a Grade 1 mortise lock alternative to BEST that fits the same 2-3/4 inch backset prep?
Hager's 3800 Series is the closest cross-brand match on prep, running a 2-3/4 inch backset in Grade 1 with escutcheon trim, for example the 3810E passage and the 3850E office lock, both rated for doors 1-3/4 to 2-1/2 inches. Understand what changes though: those Hager models are passage and office functions, not a hotel shutout function, so they are prep-compatible but not function-compatible with a 45H hotel lock. If the requirement is genuinely hotel function with a keyed shutout, stay with the 45H.
19) The door does not need to lock at all. Is there a simpler mortise lock than the BEST 45H?
Yes. The 45H is keyed and carries a 1 inch throw deadbolt plus the hotel shutout mechanism, which a hall or closet door has no use for. The Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, and the Falcon MA101 is a Grade 1 heavy duty mortise passage lock in the MA Series with field reversible operation and a fire rating. If you want to keep the escutcheon look of the 45H on a passage opening, the Hager 3810E is a 3800 Series Grade 1 passage mortise lock with escutcheon and the same 2-3/4 inch backset, for doors 1-3/4 to 2-1/2 inches thick.
20) Is a Sargent 4874 mortise deadbolt a substitute for a BEST 45H?
No. The Sargent 4874 is a double cylinder mortise deadbolt in the 4870 Series with a 2-3/4 inch backset - it is a bolt only, with no latch and no lever. The BEST 45H combines a 3/4 inch throw stainless steel latchbolt with a 1 inch throw deadbolt and carries lever or knob trim. The backsets match at 2-3/4 inches, but the 4874 supplements a latching lockset rather than replacing one. The same distinction applies to the Kaba Ilco 185 Series, which is a deadbolt function mortise lock.
21) What is the difference between the BEST 45H and the Schlage L0170 - can I order one for a door that only needs a pull?
They do different jobs. The Schlage L0170 is a Grade 1 heavy duty non-keyed half dummy mortise lever trim in the L Series for 1-3/4 inch doors - the lever is fixed and there is no latch or bolt behind it. The BEST 45H is a working keyed hotel function lock with a latchbolt and deadbolt. Use the L0170 on an inactive leaf or a pull-only opening and the 45H where the door has to latch and lock.
22) I need a mortise lock for a bathroom or bedroom door in the same building as my BEST 45H guest room locks. What matches?
Privacy function is the one to order there, since the 45H is a keyed hotel function lock. The Cal-Royal NM8440 is a Grade 1 heavy duty privacy mortise lockset with deadbolt for 1-3/4 inch doors, and the Hager 3840S is a 3800 Series Grade 1 privacy mortise lock with a 2-3/4 inch backset for doors 1-3/4 to 2 inches thick. The 3840S shares the 45H's 2-3/4 inch backset, so the door machining carries over.
23) I want a keyed heavy duty mortise lock for an office door rather than a guest room. What is comparable to the BEST 45H?
Office and entrance function is the closer fit there. The Cal-Royal NM8050 is a Grade 1 heavy duty office/entrance mortise lockset with an auxiliary deadlatch for 1-3/4 inch doors. If the office does not need a key, the Hager 3850E is a 3800 Series Grade 1 non-keyed office mortise lock with lever and escutcheon on a 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inches. The 3850E carries escutcheon trim and the same 2-3/4 inch backset as the 45H, so it sits naturally alongside 45H openings in the same building.
24) What are the 626AM and 630AM antimicrobial finishes on the BEST 45H for?
626AM is satin chrome plated and 630AM is satin stainless steel, both with BEST's UltraShield antimicrobial protected coating, which inhibits growth of bacteria and other microbes on the hardware surface. BEST recommends it where cleanliness is a priority: hospital and healthcare, elderly care, education, transportation, food service, and hospitality. On a hotel or assisted living corridor where housekeeping is wiping levers constantly, that is the finish line to specify.
25) Are Emtek mortise entrance locksets an alternative to the BEST 45H for a hotel or apartment entry?
Not for a working opening. The Emtek Brisbane 3019, Memphis 3102, Hamilton 3104 and Manhattan 3106 mortise entrance locksets are all dummy function - decorative trim with no latching mechanism behind it. The BEST 45H is a heavy duty commercial hotel function lock with a stainless steel latchbolt and a 1 inch throw deadbolt. Order the Emtek pieces for inactive leaves and matching aesthetics, and the 45H where the door has to secure.
26) A Sargent 130KB thumbturn came up when I searched mortise locks. Does it replace a BEST 45H?
No - it is a component, not a lockset. The Sargent 130KB is a standard duty mortise thumbturn in the 8200 Series, and the 130W is a standard duty mortise thumbturn with a round backplate in the 7800 Series. Both are inside turn pieces. The BEST 45H is a complete heavy duty mortise lock with case, latchbolt, deadbolt and escutcheon trim.
