BEST 45H02DT3H626 – Frequently Asked Questions

1) What does the double dummy function on the BEST 45H mortise lock actually do?
Double dummy means no latch operation at all. The 45H 2DT is a non-keyed trim set with fixed levers on both sides, used to match the look of working mortise locks on inactive leaves of pairs, closet doors, or false doors. Nothing retracts, so the door needs a separate ball catch, roller catch, or flush bolts to stay shut.
2) Will the BEST 45H double dummy fit a door thicker than 1-3/4 inches?
Standard 45H configuration is built for 1-3/4 inch doors. Thick-door configurations are available up to 5 inches, but the thickness has to be specified when the order is placed, it isn't field-adjustable.
3) What rose and lever options do I have to pick when ordering the BEST 45H dummy trim?
Three decisions. Rose style is H (2-3/4 inch flat), R (2-3/4 inch concave), or S (3-1/2 inch flat). Lever style covers 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. Then finish. Match all three to the working locks on the adjacent doors or the dummy will read as a mismatch.
4) I need a working non-keyed lock, not a dummy. What should I order instead?
A dummy has no latch, so it will not hold a door closed. For a latching non-keyed opening, look at a passage function: the Schlage PM010 Grade 1 passage mortise lock, the Falcon MA101 Grade 1 heavy duty mortise passage lock, or the Hager 3810S Grade 1 passage mortise lock with rose and a 2-3/4 inch backset that matches the BEST 45H prep. For privacy on a restroom or bedroom, the Hager 3840S or Cal-Royal NM8440 privacy mortise locks are the functions to specify.
5) What is the closest Grade 1 commercial equivalent to the BEST 45H double dummy mortise lock from another manufacturer?
The Schlage L0170 is the nearest commercial cross-brand match: it is a Grade 1, heavy duty, non-keyed mortise lever lock with a dummy function for doors 1-3/4 inches thick. The difference to confirm before ordering is how many sides you need trimmed. The BEST 45H 2DT is a double dummy, meaning fixed trim on both faces of the door, while the L0170 is half dummy trim for a single face. For an inactive leaf of a pair of doors that needs a lever on both sides, you would need two halves of the Schlage or the single BEST double dummy.
6) I need the lever to actually retract a latch, not just sit there. What should I order instead of the 45H double dummy?
The 45H 2DT is a dummy function, so the trim is fixed and there is no latch to operate. For an opening that needs the lever to retract a latch with no locking, a passage mortise lock is the right call. The Schlage PM010 is a Grade 1 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 is a Grade 1 passage mortise lock with rose trim on a 2-3/4 inch backset matching the 45H backset.
7) Can I key the BEST 45H double dummy or add a cylinder later?
No. The 2DT double dummy is a non-keyed device with no cylinder and no working latch. If you need a keyed opening on that leaf, order a keyed 45H function instead; keyed 45H locks are supplied with SFIC prep less core, so you add a small format interchangeable core to match your existing BEST keying.
8) Which finishes does the BEST 45H dummy come in, and which one should a hospital specify?
Fourteen finishes: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 618 bright nickel, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, 626AM, 630 satin stainless, 630AM, and 690 statuary dark bronze. For healthcare, elderly care, education, transportation, food service, and hospitality, the AM finishes (626AM and 630AM) carry the UltraShield antimicrobial coating that inhibits bacterial growth on the hardware surface. Note that 613 is meant to wear to an antique look over time.
9) Is the BEST 45H dummy handed, or can one part number cover both doors of a pair?
Double dummy trim is non-handed in practice. The 45H case is field reversible, the latch rotates 180 degrees without opening the case, and the cylinder retainer is non-handed, so BEST builds the series to change handing in the field. With no latch function on a dummy, the trim installs either way.
10) What grade is the BEST 45H series certified to?
ANSI A156.13, Series 1000, Grade 1 Operation and Strength, Grade 2 Security. The design also meets the intent of ANSI A117.1 section 404.2.6. If a project demands Grade 1 Security, BEST points you to the 47H series, which is A156.13 Series 1000 Grade 1 for operational, strength, and security.
11) Is there a simpler dummy trim if I don't want a full mortise dummy on an inactive leaf?
There is. A mortise dummy like the BEST 45H 2DT requires the full mortise pocket, so it is the right call when the surrounding doors carry mortise locks and you want the prep and appearance to match. If the opening has no mortise prep, a half dummy such as the Schlage L0170 non-keyed mortise dummy trim covers one side only. For decorative residential openings, Emtek's mortise dummy locksets (3019 Brisbane, 3102 Memphis, 3104 Hamilton, 3106 Manhattan) are the ornamental route rather than the commercial one.
12) Will BEST 45H rose trim match the escutcheon trim on my other doors?
No. The 2DT RS configuration is rose trim, either a 2-3/4 inch flat or concave rose or a 3-1/2 inch flat rose. If the adjacent openings use escutcheon plates, the footprint on the door face will not line up visually. Order the escutcheon trim version of the 45H for those openings instead.
13) For a residential or decorative interior door, is there a simpler dummy mortise option than the BEST 45H?
Emtek's mortise dummy sets are the decorative-side alternative. The 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan are all mortise entrance locksets in dummy function with distinct trim designs. The BEST 45H 2DT is the commercial-duty path: heavy duty, rated for commercial use, with rose trim choices in flat 2-3/4 inch, concave 2-3/4 inch and flat 3-1/2 inch and finishes from bright brass through satin stainless. Choose on appearance and the duty level the opening actually sees.
14) If I am standardizing a building on BEST 45H trim, what keyed mortise locks pair with it on the active doors?
Within the same commercial mortise class, the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option, and the Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset for 1-3/4 inch doors. The 45H 2DT covers the inactive leaves and closet faces with a non-keyed dummy; the 45H itself is supplied with an SFIC prep less core, so keying plans should be confirmed against whichever keyed series you pair it with.
15) For a behavioral health unit, is the BEST 45H double dummy appropriate or is there an anti-ligature option?
The 45H 2DT uses conventional lever and knob trim styles, including curved levers with and without return, gull wing, contour with angle return and a round knob, and it offers 626AM and 630AM antimicrobial finishes for healthcare. Where ligature resistance is the governing requirement, TownSteel's MRX line addresses it directly: the MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, and the MRX-A-01 is the ligature resistant arch trim version in satin stainless. Marks USA 5PDN is a Grade 1 ligature resistant hospital passage push/pull paddleset.
16) The opening needs credential access, not fixed trim. What replaces the BEST 45H double dummy?
The 45H 2DT is a non-electronic, non-keyed dummy, so it provides no access control at all. For an electrified mortise opening, the TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors, the Schlage CO-100 is a Grade 1 heavy duty standalone electronic mortise lock with keypad reader, and the Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock. Confirm the door prep matches the electrified case before swapping.
17) For a bathroom or bedroom door, what should I order instead of the 45H double dummy?
A dummy has no latch or locking, so it will not secure a bath or bedroom. For privacy in a mortise prep, 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, matching the 45H backset, and the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors.
18) Is the BEST 45H dummy suitable for high traffic commercial buildings, or is it just decorative trim?
It is built to the same commercial heavy duty standard as the working 45H locks: 0.095 inch cold rolled steel case, cover and armored front, zinc dichromate plated for corrosion resistance, with a roller bearing hub for smooth lever feel. That matters on a dummy too, because the lever still gets pushed and pulled all day on an inactive leaf. Typical placements are office buildings, schools, healthcare, retail, industrial, multi-tenant residential, and government facilities.
