BEST 45H0LB3J606VIT – 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 builds a thick-door configuration covering doors up to 5 inches, and you have to specify the actual door thickness when you order. There is no field adjustment for that, so measure the leaf before placing the order.
2) Do I have to specify handing on the BEST 45H mortise lock, or is it reversible in the field?
Handing is a required selection: left hand, right hand, left hand reverse, or right hand reverse. That said, the latchbolt itself is field reversible, rotating 180 degrees without opening the case, and the auxiliary bolt and cylinder retainer are non-handed. So if a door gets rehung or the wrong hand shows up on site, a locksmith can swap latch direction without tearing the lock apart.
3) What grade is the BEST 45H mortise lock, and is it Grade 1 for security as well as strength?
The 45H is certified to ANSI A156.13, Series 1000, Grade 1 for Operation and Strength, but Grade 2 for Security as built. To reach Grade 1 Security you must use a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) with escutcheon trim, or a 1EK7K4 high security cylinder with sectional trim. If your spec calls for Grade 1 across all three categories on a keyed opening, BEST's 47H Series carries Grade 1 Operational, Strength and Security. The 45H design also meets the intent of ANSI A117.1 section 404.2.6.
4) What other Grade 1 privacy mortise locks could I use instead of the BEST 45H?
Two straightforward mechanical alternatives: the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors, and the Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset covering 1-3/4 to 2 inch doors. Neither of those carries the visual thumbturn indicator that the 45H does, so if the requirement is status indication on a restroom or exam room, stay with the 45H. If the opening needs classroom-style indication instead of privacy, the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset with an 8-1/2 x 2-3/4 x 7/16 inch steel escutcheon.
5) What is another Grade 1 privacy mortise lock with a 2-3/4 inch backset if the BEST 45H is not the right fit?
The Hager 3840S is a Grade 1 privacy/bed/bath mortise lock with a 2-3/4 inch backset, listed for doors 1-3/4 inch to 2 inch thick. The BEST 45H privacy lock also uses a 2-3/4 inch backset and adds a visual thumbturn indicator that shows a padlock icon open for unlocked and closed with red paint for locked. If the indicator is not required by the spec, the 3840S covers the same privacy opening; if occupancy status has to be readable from the corridor, stay with the 45H.
6) What should I use if the opening needs a keyed classroom function rather than privacy?
The BEST 45H covered here is a non-keyed privacy function. For a keyed classroom opening, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors, and the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch for 1-3/4 inch doors. For classroom security with a status indicator like the BEST thumbturn indicator, the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset with ANSI strike and a steel escutcheon 8-1/2 inch H x 2-3/4 inch W x 7/16 inch.
7) For a behavioral health or ligature resistant opening, is the BEST 45H the right mortise lock?
For anti-ligature openings 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, and the MRX-A-01 is the same passage function with satin stainless ligature resistant arch trim. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel. The BEST 45H uses conventional lever styles including curved, gull wing and round knob with rose or escutcheon trim, which is a standard commercial lever profile rather than a ligature resistant one.
8) Can I use the BEST 45H on a narrow stile aluminum or glass door?
No. The BEST 45H is a standard commercial mortise lock with a 2-3/4 inch backset built for 1-3/4 inch doors, with a thick door configuration for doors up to 5 inch. For narrow stile aluminum storefront, the Alarm Lock DL1300NW is a Trilogy Networx wireless electronic mortise lock with keypad made for Adams Rite deadlatches, and for all-glass doors the Kaba Ilco BR Series is a glass door bottom rail lock.
9) What does the visual indicator on this BEST 45H privacy lock actually show?
A padlock icon at the thumbturn. Open padlock means unlocked; closed padlock with red paint means locked. That is what a restroom, exam room, or lactation room needs so nobody has to try the lever to find out whether it is occupied. The indicator is part of the thumbturn assembly on the LB privacy function.
10) Is the BEST 45H privacy lock keyed, and do I need to order a cylinder with it?
The privacy version is non-keyed, so there is no key cylinder in the normal operating function. It ships less cylinder and less core, and the pictured configuration has no housing and no core. If you want the emergency outside release on a privacy lock, confirm the function code you need before ordering, because the LB privacy function here operates from an inside thumbturn rather than a key.
11) I need a privacy mortise lock for a hospital restroom. Which finish should I be specifying?
For healthcare, BEST offers two UltraShield antimicrobial finishes: 626AM satin chrome and 630AM satin stainless steel. The UltraShield coating inhibits growth of bacteria and other microbes on the hardware surface, and BEST recommends it anywhere cleanliness is a priority, including hospital and elderly care, education, transportation, food service and hospitality. If antimicrobial is not required, plain 626 satin chrome and 630 satin stainless are the standard institutional picks.
12) What lever and trim options do I choose from on the BEST 45H, and can I match the other doors in my building?
Three trim styles are offered: J wrought escutcheon, H rose and R rose. Lever styles cover 12 solid tube with no return, 3 solid tube with return, 14 curved with return, 16 curved without return, 15 contour with angle return, 17 gull wing, and 4 round knob. Fourteen 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 622 matte black. That is enough range to match most existing BEST openings, so pull the lever number and finish number off a lock you already have in service and order to match.
13) Is there an electronic version if I want access control on the same opening instead of a mechanical privacy lock?
The 45H is fully mechanical, with no electronic components. If the opening needs credentials or codes, the Schlage CO-100-MS standalone electronic mortise lock is a Grade 1 privacy function unit with a keypad reader for 1-3/4 inch doors, and the Schlage LE Series LEBMB-ADD is a mobile-enabled mortise lock covering privacy, office and apartment functions. Both replace the mechanical privacy lock rather than supplement it, so the mortise pocket carries the electronic case instead.
14) Is there a privacy mortise lock with a deadbolt instead of the BEST 45H thumbturn indicator?
The Cal-Royal NM8440 is a Grade 1 privacy/bed/bath mortise lockset with a deadbolt, built for 1-3/4 inch doors. The BEST 45H privacy lock carries a stainless steel deadbolt with a 1 inch throw and a 3/4 inch throw latchbolt, plus the visual thumbturn indicator. Both are non-keyed privacy functions; the difference is the indicator display and the BEST interchangeable core trim architecture.
15) If I only need latching with no locking at all, what replaces the BEST 45H privacy lock?
A passage mortise lock does that job. The Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating, and the Hager 3810E is a Grade 1 passage mortise lock with escutcheon trim and a 2-3/4 inch backset for doors 1-3/4 inch to 2-1/2 inch. The Hager 3810S is the same passage function with rose trim. The BEST 45H privacy version adds the deadbolt and thumbturn indicator that a passage lock has no mechanism for.
16) What is the difference between the BEST 45H privacy lock and a Schlage PM010 passage mortise lock?
The Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, so both are non-keyed mortise products. The PM010 latches only. The BEST 45H privacy version adds a 1 inch throw stainless deadbolt operated by a thumbturn with a visual indicator, an armored front surrounding latch and deadbolt, and an 8 inch H x 1-1/4 inch W faceplate. Choose the PM010 for corridor and closet doors and the 45H where the room must be secured from the inside.
17) I need a keyed storeroom mortise lock for the same door prep as the BEST 45H - what are the options?
The Accentra 8805FL is a Grade 1 storeroom mortise lock from the 8800 Series with an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. The BEST 45H is supplied less cylinder and is non-keyed in the privacy configuration, so a storeroom opening needs one of the keyed bodies rather than a cylinder added to this privacy lock.
18) Is an Emtek Brisbane or Baldwin 6301 mortise lock an equivalent to the BEST 45H?
They serve different openings. The Emtek 3019 Brisbane and 3102 Memphis are dummy function mortise entrance locksets with no working latch. The Baldwin 6301 is an entrance/apartment mortise lock body with a 2-1/2 inch backset for doors 1-3/4 inch and over. The BEST 45H is a heavy duty commercial privacy lock with a 2-3/4 inch backset, so the Baldwin body will not drop into the same door prep and the Emtek dummies do not latch at all.
19) What mortise product should I specify for a dormitory or corridor opening instead of the BEST 45H privacy function?
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. That gives keyed outside control with a deadbolt, where the BEST 45H privacy version is non-keyed and controls the deadbolt from the inside thumbturn with a visual status indicator.
20) For an electrified opening tied to access control, what mortise lock replaces the BEST 45H?
The Command Access ML190 Series is a heavy duty motorized mortise lock in storeroom function with field selectable fail safe or fail secure operation on 24VDC, and the Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit, on 12/24VDC for 1-3/4 inch doors. The BEST 45H has no electronics and cannot be tied into a card or strike release circuit.
21) How durable is the BEST 45H case for a high traffic restroom door?
Heavy duty commercial build throughout. The case, cover and armored front are 0.095 inch cold rolled steel with zinc dichromate plating for corrosion protection, the latchbolt is solid one piece stainless steel with 50 percent more surface contact against the strike, and the hub runs on roller bearings. The armored front wraps both the latch and deadbolt for lateral strength. The lever return spring sits in the trim rather than the case, which is what keeps levers from drooping after heavy cycling.
22) Is there an access controlled classroom mortise lock with RFID if the BEST 45H mechanical indicator is not enough?
The TownSteel FME-2000 Series is a Grade 1 heavy duty mortise lockset with RFID technology in classroom function for 1-3/4 inch doors, and the FME-4000 Series is an electronic intruder classroom mortise lockset with RFID, also Grade 1 heavy duty for 1-3/4 inch doors. The BEST 45H matches them on heavy duty rating but is fully mechanical, with status shown by the padlock indicator on the thumbturn rather than credentials and audit.
23) Can a Sargent 4874 mortise deadbolt do the same job as the BEST 45H?
Only partly. The Sargent 4874 is a double cylinder mortise deadbolt from the 4870 Series with a 2-3/4 inch backset, matching the 45H backset, but it is deadbolt only with no latch and no lever trim. The BEST 45H combines a 3/4 inch throw latchbolt, a 1 inch throw deadbolt and lever or knob trim in one case. The Kaba Ilco 185 Series is likewise a deadbolt function mortise lock with no handing.
