BEST 45H02DT3J626AM – Frequently Asked Questions

1) What does the double dummy function on the BEST 45H mortise lock actually do?
Double dummy means trim on both sides with no latch action at all. The 45H 2DT is non-keyed and has no working latchbolt operation from either lever, so it is a pull only. Use it on the inactive leaf of a pair, on a closet or cabinet face, or anywhere you want the look of the other mortise locks in the building without any latching. If the door has to stay shut or latch, you need a passage or office function instead.
2) Will the BEST 45H double dummy fit a 1-3/4 inch commercial door?
Yes. The standard 45H configuration is built for doors 1-3/4 inches thick, which is the usual commercial thickness. For thicker doors, BEST offers a thick door configuration up to 5 inches, and the thickness has to be specified on the order. The lock uses a 2-3/4 inch backset.
3) Can I match this dummy to the keyed BEST 45H locks already on my other doors?
That is the usual reason to buy it. It shares the 45H case, the 2-3/4 inch backset, the 8 inch stainless, brass or bronze faceplate and the same escutcheon and lever families, so it lines up visually with the working 45H locks down the hall. Pick the same finish and lever style as the existing openings. Finishes run from 605 bright brass through 630 satin stainless and 690 statuary dark bronze.
4) What do I have to specify when ordering a BEST 45H escutcheon dummy?
Three choices plus door thickness. Trim style: J wrought escutcheon, M forged escutcheon, or N forged escutcheon with concealed cylinder. Lever or knob style: 12 solid tube no return, 3 solid tube with return, 4 round knob, contour with angle return, curved with or without return, or gull wing. Then finish, 14 options from bright brass to the antimicrobial 626AM and 630AM. If the door is thicker than 1-3/4 inches, state the thickness so you get the thick door configuration.
5) What is the closest alternative to the BEST 45H double dummy mortise lock if only one side of the door needs trim?
The BEST 45H with escutcheon trim in the 2DT double dummy configuration puts non-keyed dummy trim on both faces of the door. When only one face needs trim, the Schlage L0170 is a Grade 1 mortise non-keyed lever lock in half dummy trim form, rated heavy duty for doors 1-3/4 inches thick. Use the half dummy where the inactive leaf is only pulled from one side, and the 45H double dummy where both faces are handled.
6) The opening needs to actually latch, not just pull - what should I use instead of a dummy mortise lock?
A dummy function has no latch at all, so it cannot hold a door closed. For a non-keyed latching mortise, the Schlage PM010 is a Grade 1 passage latch mortise lock for 1-3/4 inch doors, and the Falcon MA101 is a Grade 1 heavy-duty mortise passage lock with field reversible operation and a fire rating. Hager also offers passage in the 3800 series: the 3810E with escutcheon trim on a 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inches, or the 3810S with rose trim.
7) Will a Falcon MESC600DT dummy escutcheon trim work in place of a BEST 45H double dummy mortise lock?
No. The Falcon MESC600DT is dummy escutcheon lever trim made for M9900 series exit devices, so it mounts to an exit device opening rather than a mortise lock pocket. The BEST 45H double dummy is a mortise product with a 2-3/4 inch backset and an 8 inch H x 1-1/4 inch W x 1/16 inch T faceplate, prepped into the door edge. Choose the MESC600DT only when the door carries an M9900 exit device.
8) My doors are prepped for a 2-1/2 inch backset - can I use the BEST 45H escutcheon dummy?
No, the BEST 45H is built on a 2-3/4 inch backset. For a 2-1/2 inch backset mortise pocket, Baldwin's 6301 entry/apartment lock body is available knob by knob or lever by lever for doors 1-3/4 inches and over, and the 6310 entry/storeroom body comes knob by knob or as the 6310190RRLS right hand reverse lever by lever for doors 1-3/8 inches and over.
9) Does the dummy version need a handing specified?
Handing is less of a concern on the dummy than on a latching 45H. The series latch is reversible 180 degrees without opening the case and the auxiliary bolt is non-handed, so the lock body itself is field reversible. What you do need to match is the escutcheon and lever orientation to the door so the levers point the right way on both faces.
10) Is the BEST 45H dummy Grade 1?
The 45H Series meets ANSI A156.13, Series 1000, Grade 1 for Operation and Strength, and Grade 2 Security. Construction is 0.095 inch cold rolled steel case, cover and armored front with zinc dichromate plating. The design also meets the intent of ANSI A117.1 section 404.2.6.
11) Do I need a cylinder or core for this lock?
No core is needed to operate it, since the 2DT dummy is non-keyed. The 45H is built with SFIC prep less core, so a cylinder opening may be present in the trim depending on style. If you want no visible cylinder at all, order the N forged escutcheon with concealed cylinder.
12) What else could I use instead of the BEST 45H double dummy?
For a Grade 1 mortise dummy from another maker, the Schlage L0170 is a half dummy lever trim in the L Series, heavy duty, rated for 1-3/4 inch doors, so it covers one face rather than two. For a decorative residential look, Emtek's mortise dummy locksets, such as the 3102 Memphis or 3104 Hamilton, are dummy function as well. If you actually need the door to latch but not lock, a passage function is the right call, for example the Falcon MA101 Grade 1 heavy duty mortise passage lock or the Hager 3810E passage mortise lock with escutcheon and 2-3/4 inch backset.
13) Can this BEST dummy go on a door with a 2-3/8 inch backset prep?
No. The 45H is a 2-3/4 inch backset lock, which is the standard commercial mortise backset. A door prepped at 2-3/8 inches, common on cylindrical residential prep, will not line up. For a shallower mortise prep, Baldwin's 6301 and 6310 mortise bodies are built on a 2-1/2 inch backset.
14) Which mortise lock should I order if the door has to lock with a key rather than be a dummy?
The BEST 45H double dummy is non-keyed with SFIC prep less core only on keyed functions of the series, so for a locking opening choose by function: Accentra 8805FL is Grade 1 storeroom in the 8800 series, Cal-Royal NM8080 is Grade 1 storeroom for 1-3/4 inch doors with an interchangeable core option, NM8050 is Grade 1 office/entrance, and Corbin Russwin ML2003 is a Grade 1 classroom mortise for 1-3/4 inch doors.
15) Is an Emtek dummy mortise lockset a substitute for the BEST 45H double dummy?
Both are dummy function mortise trim, but they are built for different openings. The BEST 45H is a commercial heavy duty product meeting ANSI A156.13 Series 1000 Grade 1 operation and strength, with a 2-3/4 inch backset, 8 inch stainless faceplate, and escutcheon trim in wrought, forged, and forged concealed cylinder styles. Emtek's dummy mortise entrance locksets - 3019 Brisbane, 3102 Memphis, 3104 Hamilton, and 3106 Manhattan - are decorative designer series. Match the 45H when the spec calls for the commercial mortise trim family already on the other doors.
16) For a behavioral health or ligature-resistant corridor, what mortise option replaces a standard escutcheon dummy?
The BEST 45H escutcheon dummy uses conventional lever and knob trim styles including curved, contour with angle return, gull wing, and round knob. For anti-ligature openings, TownSteel offers the MRX-A-01 passage function with ligature resistant arch trim in satin stainless and the MRX-L-01 passage function anti-ligature lever mortise lockset, both Grade 1 heavy duty for 1-3/4 inch doors. Marks USA 5PDN is a Grade 1 hospital passage push/pull paddleset described as ligature resistant and ADA compliant.
17) What should I specify instead of a mechanical dummy mortise when the opening needs credential or keypad access?
The BEST 45H double dummy is non-electronic and non-keyed. For electronic mortise openings, the Schlage CO-100 is a Grade 1 standalone electronic mortise lock with keypad reader in privacy function for 1-3/4 inch doors, Accentra nexTouch NTM623-NR is a Grade 1 mortise lock with capacitive touchscreen keypad and cylinder override, and TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID. Schlage's LEMD-GRW is a Grade 1 ENGAGE wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating.
18) What non-keyed mortise option gives privacy for a restroom instead of a dummy?
A dummy such as the BEST 45H 2DT does not lock. For privacy, Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors, and Hager 3840S is a 3800 series Grade 1 privacy mortise on a 2-3/4 inch backset for doors 1-3/4 to 2 inches. If the room only needs office-style non-keyed control, Hager 3850E is an office function mortise with lever and escutcheon on a 2-3/4 inch backset.
19) Can I use a cylindrical passage lock instead of a mortise dummy to cut down on door prep?
The BEST 45H is a mortise lock requiring a pocket in the door edge. If the opening is not already mortise prepped, the Schlage PC10 is a Grade 1 passage cylindrical lock, non-keyed with rose, for 1-3/4 inch doors, which uses a bored prep instead. Note it is a latching passage function rather than a dummy, so it will hold the door closed.
20) For a healthcare facility standardizing on antimicrobial hardware, how does the BEST 45H compare with other Grade 1 mortise choices?
The BEST 45H offers 626AM satin chrome and 630AM satin stainless steel with UltraShield antimicrobial protected coating, which is why it is specified for hospital, elderly care, and food-service openings. Among Grade 1 mortise peers, Marks USA 5PDN is a hospital passage push/pull paddleset in satin stainless steel, and TownSteel MRX-A-01 is a Grade 1 heavy duty satin stainless ligature resistant arch trim mortise lockset. Those two address touch style and ligature resistance, while the 45H addresses coated finish.
21) Which finish should I use for a hospital or food service door?
Two antimicrobial options: 626AM satin chrome and 630AM satin stainless, both with the BEST UltraShield coating that inhibits growth of bacteria and other microbes on the hardware surface. BEST recommends it for hospital and healthcare, elderly care, education, transportation, food service and hospitality openings.
22) Is the BEST 45H dummy an electronic or access control lock?
It is purely mechanical, non-electronic and non-keyed. If you need credentialed access on a mortise prep, look at electronic mortise locks such as the TownSteel FME-2000 Series Grade 1 with RFID, the Dormakaba E-Plex 2066 pushbutton keyless mortise lock, or the Schlage CO-100 standalone electronic mortise lock.
23) I only need a thumbturn or deadbolt in the existing mortise pocket, not a full dummy trim set - what are the options?
The BEST 45H escutcheon dummy covers the door face with an 8 inch H x 1-1/4 inch W faceplate and full escutcheon trim. For a thumbturn only, Sargent offers the 130KB standard mortise thumbturn in the 8200 series and the 130W mortise thumbturn with a round backplate in the 7800 series. For deadbolt only, the Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset and the Kaba Ilco 185 series is a no-handing mortise deadbolt.
