BEST 45H0N3J626 – Frequently Asked Questions

1) Will the BEST 45H passage mortise lock fit a door thicker than 1-3/4 inches?
The standard 45H configuration is built for 1-3/4 inch doors, which is the usual commercial thickness. For anything thicker, BEST builds a thick door configuration up to 5 inches, but you have to call out the actual door thickness when you place the order. It is not field adjustable after the fact, so measure the leaf before you order.
2) Does the BEST 45H passage function lock take a key or a cylinder?
No. The N passage function is non-keyed, so the levers always retract the latch from both sides and the door is never locked. It is the lock for a corridor, hall, or closet opening where you only want a latched door. If you need to secure the opening, you want a keyed 45H function instead.
3) Do I have to specify handing on a BEST 45H mortise lock?
No handing to specify. The 45H case is non-handed, and the latchbolt rotates 180 degrees to change hand without opening the case. The cylinder retainer and auxiliary bolt are non-handed as well, so one lock covers left and right hand openings.
4) Will the BEST 45H latch into the strike already in my frame?
The latchbolt throws 3/4 inch, which is the standard mortise latch projection, so it will engage a correctly prepped ANSI mortise strike. The latch itself is solid one-piece stainless with roughly 50 percent more contact surface against the strike than a conventional latch, and it is oil impregnated for anti-friction action. If the existing strike was cut for a 2-3/4 inch backset mortise case you are generally in the same prep.
5) What ANSI grade is the BEST 45H mortise lock rated to?
The 45H Series meets ANSI A156.13, Series 1000, Grade 1 for Operation and Strength, with a Grade 2 Security rating. The design also meets the intent of ANSI A117.1 section 404.2.6 for accessible operation. On the passage function the security rating is academic since there is no cylinder, but the Grade 1 operational rating is what matters for high traffic corridors.
6) What is an equivalent Grade 1 mortise passage lock to the BEST 45H non-keyed passage if I need a different brand?
The Falcon MA101 is a Grade 1 heavy duty mortise lock in a passage/hall/closet function with field reversible operation, matching the BEST 45H non-keyed passage function on grade, duty level and non-locking operation. The Hager 3810E is also a Grade 1 passage mortise lock with a 2-3/4 inch backset and escutcheon trim, which is the closest match to the 45H escutcheon trim configuration and its 2-3/4 inch backset. Schlage PM010 is another Grade 1 mortise passage latch for 1-3/4 inch doors.
7) I want a passage mortise lock with rose trim instead of escutcheon plates. What are my options?
The BEST 45H passage lock is offered with escutcheon trim in wrought, forged, and forged concealed cylinder styles. If the opening calls for a small round rose instead, the Hager 3810S is a Grade 1 passage mortise lock with rose trim and a 2-3/4 inch backset, the same backset as the 45H. Schlage PM010 is a Grade 1 mortise passage latch for 1-3/4 inch doors as another rose-trim-scale alternative.
8) The door does not have a mortise pocket. Is there a simpler passage lock that installs in a bored door?
The BEST 45H is a mortise lock, so it requires a mortise pocket cut into the door edge. For a door prepped with a standard bored hole instead, the Schlage PC10 is a Grade 1 passage cylindrical lock, non-keyed with rose, for 1-3/4 inch doors. It gives you the same passage operation without mortise prep.
9) I need the same look as the BEST 45H but the room has to lock. What should I order instead?
The 45H passage function is non-keyed and does not lock. For a keyed opening in mortise format, the Accentra 8805FL is a Grade 1 storeroom mortise lock and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option, which suits sites already keying to small format cores. For a classroom function, Corbin Russwin ML2003 and Cal-Royal NM8070 are both Grade 1 classroom mortise locksets for 1-3/4 inch doors. For bed and bath privacy without a key, Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt and Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset.
10) For a behavioral health or psychiatric unit, is the BEST 45H the right passage mortise lock?
The 45H passage is a commercial heavy duty mortise lock with lever and knob trim options, but it is not an anti-ligature design. For ligature-resistant openings, the TownSteel MRX-A-01 is a Grade 1 heavy duty passage function mortise lockset with ligature resistant arch trim in satin stainless steel, and the MRX-L-01 is a Grade 1 heavy duty anti-ligature lever passage mortise lockset, both for 1-3/4 inch doors. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant.
11) Will a Baldwin 6301 mortise lock body drop into the same prep as the BEST 45H?
No. The Baldwin 6301 entry/apartment mortise lock body uses a 2-1/2 inch backset, while the BEST 45H is built on a 2-3/4 inch backset, so the spindle and cylinder holes do not line up. The Baldwin 6301 is also an entrance/apartment function rather than non-keyed passage. If you are matching an existing 2-3/4 inch mortise prep, stay with a 2-3/4 inch backset lock such as the Hager 3810E passage mortise.
12) What is the difference between the J, M, and N escutcheon trims on the BEST 45H?
All three are escutcheon plates rather than roses. J is a wrought escutcheon, M is forged, and N is a forged escutcheon with a concealed cylinder opening. On a non-keyed passage lock the N trim gives you a clean plate with no cylinder showing, which is why it pairs with this function. Choose the trim first, then the lever style, then the finish.
13) Which lever and knob styles can I get on the BEST 45H escutcheon mortise lock?
Seven trim designs: 12 solid tube with no return, 3 solid tube with return, 4 round knob, contour with angle return, curved with return, curved without return, and gull wing. Lever designs with a return are the usual pick where an accessible or code-compliant pull is specified. The 4 is the only knob in the group.
14) Does the BEST 45H passage lock have a deadbolt?
The 45H case is built with a deadbolt provision carrying a 1 inch stainless throw, and the armored front wraps both the latch and the deadbolt for lateral strength. The N passage function itself is non-keyed operation, so plan the opening around the latch. If you need a working deadbolt on a non-keyed door, look at a privacy function such as the Cal-Royal NM8440 privacy mortise lockset with deadbolt.
15) Will the BEST 45H hold up on a high traffic school or hospital corridor door?
It is built for that duty. The case, cover, and armored front are 0.095 inch cold rolled steel with zinc dichromate plating for corrosion resistance, four case cover screws at the corners, and an interlocking armored front and cover at the latch. The hub runs on roller bearings, and the anti-friction stainless latch is curved for cycle life. It carries the Grade 1 operation and strength rating under ANSI A156.13 Series 1000.
16) For a hospital or food service corridor, how does the BEST 45H compare to other passage mortise options on hygiene?
The BEST 45H passage lock 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, and is recommended for healthcare, elderly care, education, transportation, food service and hospitality. Among comparable passage mortise locksets, the Marks USA 5PDN is a Grade 1 hospital passage push/pull paddleset in satin stainless steel, which removes the grasping motion but does not carry an antimicrobial coating designation.
17) Is the Schlage L0170 dummy trim a substitute for the BEST 45H passage lock?
No. The Schlage L0170 is a Grade 1 mortise non-keyed lever half dummy trim with a dummy function, meaning the lever is fixed and there is no latch. The BEST 45H passage function operates a latchbolt with a 3/4 inch throw from either side. Use a dummy like the L0170 or the Emtek 3102 Memphis dummy only on an inactive leaf or a pull-only door, not where the door has to latch.
18) We want access control on the opening. What mortise locks should we look at instead of the BEST 45H?
The BEST 45H is a mechanical, non-electronic mortise lock. For credential-based access on a mortise prep, the Schlage LEMD-GRW is a Grade 1 ENGAGE wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating, and the TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors. For keypad entry, the Alarm Lock DL3500CR is a Grade 1 classroom electronic mortise lock with 300 user codes, and the Accentra NTM623-NR nexTouch Generation 3 mortise lock uses a capacitive touchscreen keypad with cylinder override.
19) What is the difference between the BEST 45H escutcheon passage lock and the Hager 3850E office lock?
Both are mortise locks with lever and escutcheon trim on a 2-3/4 inch backset. The BEST 45H in this configuration is a non-keyed passage function, so the latch retracts from either lever at all times. The Hager 3850E is a non-keyed office function, which allows the outside lever to be held in a locked or unlocked state from the inside. Choose the office function where staff need to secure the room without a key, and passage where the door only needs to latch.
20) Can I use the BEST 45H on a 1-5/8 inch door?
The standard 45H configuration is built for 1-3/4 inch doors, with thick door configurations available up to 5 inches when the thickness is specified at time of order. For thinner or narrower ranges, the Alarm Lock DL2700CR and DL3500CR electronic mortise locks are listed for 1-5/8 inch to 1-7/8 inch doors. Baldwin 6310 mortise lock bodies cover 1-3/8 inch and over.
21) We need a dormitory or corridor function mortise lock rather than plain passage. What is comparable?
The Sargent 7925 is a Grade 1 heavy duty mortise lock in a corridor/dormitory exit function with rose trim and a single cylinder deadbolt, which keeps free egress while allowing the outside to be secured. The BEST 45H in passage configuration is non-keyed and has no deadbolt control, so the Sargent 7925 is the better fit where residents need to secure the room.
22) I need to match existing hardware finishes across a building. What finishes does the BEST 45H come in?
Fourteen finishes: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 oxidized satin bronze oil rubbed, 618 bright nickel, 619 satin nickel, 622 flat black, 625 bright chrome, 626 satin chrome, 626AM, 630 satin stainless, 630AM, and 690 dark bronze. Two behave differently over time: 613 is meant to wear to an antique look, and 690 stays a dark brown. If you are standardizing a facility, 626 and 630 are the common commercial pair.
23) Is the BEST 45H an electronic or access-control lock?
No, it is a purely mechanical mortise lock with a roller bearing hub and a lever return spring housed in the trim to resist lever droop. If you need credential or keypad access on a mortise prep, look at electronic mortise locks such as the Schlage CO-100 standalone keypad mortise lock or the TownSteel FME-2000 Grade 1 RFID mortise lockset.
24) Is a Sargent 4874 mortise deadbolt an alternative to the BEST 45H?
No, they do different jobs. The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset with no latch and no lever, so the door has to be pushed or pulled by separate trim. The BEST 45H passage function provides the operating latch and lever or knob trim. The Kaba Ilco 185 Series is likewise a deadbolt function mortise lock. Pair a deadbolt with passage trim only if the door needs a separate deadbolt above the latch.
