BEST 9K01DT14C626 – Frequently Asked Questions

1) What does a BEST 9K 1DT dummy lever actually do, and does it latch?
Nothing mechanical. The 1DT is a single, surface-mounted lever for an inactive door or a non-latching door, so it has no latchbolt, no cylinder, and the lever doesn't turn anything. It's a pull. If you need the door to stay closed on its own, you want a passage function like the Falcon K101 or the Corbin Russwin CL3110 instead, both Grade 1 non-keyed cylindrical levers with a working latch.
2) What door prep does a BEST 9K dummy lever need, and can I use an existing 2-1/8 inch bore?
The 9K trim mounts to standard ANSI A115.2 prep, which is the 2 1/8 inch diameter chassis bore most commercial doors already carry, plus two additional 5/16 inch diameter through-bolt holes at the 12 o'clock and 6 o'clock positions. So an existing bored door usually takes it, but you drill the two through-bolt holes if they aren't there. Backset is 2 3/4 inch standard, with 3 3/4 inch and 5 inch available for wider stiles.
3) Do I have to order a handed dummy lever for the 9K 1DT, left or right?
No handing to specify. The 9K 1DT is non-handed, so one part works on either side of the opening and you can stock a single item for a whole building. That's a difference worth knowing if you're cross-shopping: Baldwin's Estate 5103 half dummy is sold as separate left-hand and right-hand parts.
4) Can I put a dummy lever on a fire rated door?
The BEST 9K Series is UL listed for use on 3-hour A label single or double swinging doors, which covers the fire door assemblies in most commercial corridors and stairwells. It also carries BHMA listing to A156.2, Series 4000, Grade 1. On a fire rated pair, the 1DT is the trim you put on the inactive leaf.
5) How do I get the dummy lever to match the other BEST 9K locks already on my doors?
Match three things on the order: lever style, rose style, and finish. Lever comes as Contour with Angle Return, Curved with Return, or Curved without Return. Rose is C (3 inch convex), D (3-1/2 inch convex), K (3 inch convex, no ring), or L (3-1/2 inch convex, no ring). Finish runs 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, 626AM antimicrobial satin chrome, and 690 statuary dark bronze. Copy those three off an existing 9K lock and the dummy will read identical down the corridor.
6) What is the closest Grade 1 dummy lever to the BEST 9K 1DT from another manufacturer?
The Accentra 455LN Augusta is the nearest straight equivalent: a heavy duty Grade 1 single dummy cylindrical lever lock in the 5400 Series. Like the BEST 9K 1DT, it is a Grade 1 dummy trim rather than a latching lockset, so it mounts on an inactive or non-latching leaf and gives a pull point without any bolt. The 9K 1DT differs in the trim range you can specify, with lever styles in Contour with Angle Return, Curved with Return, and Curved without Return, and roses in C, D, K, and L.
7) The door needs a lever that actually retracts a latch, not a dummy. What should I order instead?
A dummy trim like the BEST 9K 1DT has no latch at all, so on a door that must stay closed and latch you need a passage function lockset. The Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers and a fire rating, covering 1-3/8 inch to 2-1/4 inch doors. The Corbin Russwin CL3110 is a Grade 1 vandal resistant passage cylindrical lever lock for 1-3/4 inch to 2 inch doors, also fire rated. Both give a latching lever at the same Grade 1 level as the 9K 1DT.
8) The door is 1-3/8 inch thick. Will the BEST 9K 1DT fit, and what fits if it does not?
The BEST 9K 1DT is built for 1-3/4 inch to 2-1/4 inch door thickness, so a 1-3/8 inch door falls below its range. For thinner leaves, the Falcon K101 Grade 1 heavy duty passage lock covers 1-3/8 inch to 2-1/4 inch, and the Dexter C1000 Grade 1 asylum function covers 1-3/8 inch to 2 inch. Both are latching functions rather than dummy trim, so they change what the opening does as well as what fits it.
9) Is a Grade 1 dummy lever overkill, or does it matter on a door that doesn't lock?
It matters where hands pull hard. The 9K 1DT is Grade 1, heavy duty, with critical latch and chassis components in brass or corrosion-treated steel, a hub-mounted torsion spring that stops lever sag, and through-bolt mounting studs into a heavy rose liner for torque resistance. A dummy takes the same yanking a passage lever does, and a sagging dummy on an inactive leaf is the one people notice. Lighter-duty alternatives exist if the traffic is low: Callan's Bentley dummy lever is Grade 2.
10) Does the BEST 9K 1DT dummy take a core or a cylinder, and can it be keyed later?
No cylinder, no core, no key. The 1DT is non-keyed dummy trim with nothing to accept a BEST core, and it can't be converted to a keyed function later. If the opening might need to lock down the road, put a keyed 9K chassis on it now rather than swapping trim twice.
11) Which rose size should I pick to cover the old holes when replacing existing lever trim?
Go to the 3-1/2 inch rose if you're covering marks or oversized prep: D Rose is 3-1/2 inch convex with a ring, L Rose is the same size with no ring. The 3 inch options are C (with ring) and K (no ring). All four sit over the standard 2 1/8 inch bore, so the larger rose buys you a half inch of coverage all round without changing the door prep.
12) Which dummy or non-latching lever should I use for a healthcare corridor?
The BEST 9K 1DT is offered in a 626AM satin chrome antimicrobial finish with an UltraShield coating that inhibits growth of bacteria and other microbes on the hardware surface, which is the reason it is specified in healthcare, elderly care, and food service settings. The Accentra 455LN Augusta is the other Grade 1 single dummy in the same class, ordered without that coating option. Where the corridor door latches rather than sitting inactive, the Dexter C1000 asylum function is a Grade 1 lock for 1-3/8 inch to 2 inch doors.
13) Is there a lighter duty dummy lever option instead of the BEST 9K 1DT?
Yes. The Callan Bentley is a Grade 2 dummy lever, one step down in ANSI grade from the Grade 1 heavy duty 9K 1DT. The Bentley suits interior openings in lower traffic, while the 9K 1DT is built for commercial heavy duty service with brass or corrosion treated steel critical components. If the opening is a closet or a rarely touched inactive leaf in a residential style corridor, the Grade 2 dummy covers it; if it is a public corridor door, the Grade 1 is the match.
14) Baldwin lists a 5103 half dummy in left and right hand. Is that the same thing as the BEST 9K 1DT?
Both are dummy function levers, but they are ordered differently. The Baldwin Estate 5103 half dummy is sold as a handed part, with separate left hand and right hand versions on the 5048 rose. The BEST 9K 1DT is non-handed, so one part covers either side of the opening. If you are standardizing a fleet of inactive leaves, the non-handed 9K 1DT removes the handing call from the order; the Baldwin requires you to determine hand per door.
15) I need dummy levers on both sides of an inactive leaf. Does the BEST 9K 1DT cover that?
The BEST 9K 1DT is single dummy trim, a single surface mounted lever, so two are needed for a two sided application. Emtek sells dummy trim as a pair, including the Arts and Crafts lever dummy pair and the Cortina lever dummy pair from the Classic brass leversets. Where the specification calls for a commercial Grade 1 heavy duty part, order the 9K 1DT per side; where a decorative pair is acceptable, the Emtek pairs come as one item.
16) What is the difference between the BEST 9K 1DT and the Design Hardware X75?
Both are Grade 1 commercial lever products, but they do different jobs. The Design Hardware X75 is a passage lever lockset with a flat lever for 1-3/4 inch doors in the X Series, so it retracts a latch. The BEST 9K 1DT is non-keyed dummy trim with no latch, intended for an inactive or non-latching leaf. Design Hardware also lists the J75 passage lever at Grade 2 for 1-3/4 inch doors if the opening does not call for Grade 1.
17) We are specifying non-keyed levers throughout a school. Which commercial options sit alongside the BEST 9K 1DT?
The BEST 9K 1DT handles the non-keyed dummy positions at Grade 1 heavy duty. For the latching non-keyed openings in the same facility, the Falcon T101 is a Grade 1 heavy duty passage lever in the T Series and the Falcon K101 is a Grade 1 heavy duty fire rated passage lock. Where a Grade 2 passage lever meets the spec, the Falcon B101 is a medium duty non-handed passage lever and the Hager 2510 is a Grade 2 passage lever for 1-3/8 inch to 2 inch doors.
18) The opening needs keyless entry with a code. Is the BEST 9K 1DT an option?
No. The BEST 9K 1DT is a non-electronic, non-keyed dummy trim with no latch and no access control of any kind. For coded access on a lever, the Lockey 1150 is a heavy duty mechanical keypad lever set with double combination in passage function for 1-1/8 inch to 2 inch doors, and the Lockey 2835DC is a double combination mechanical keyless lever lock with passage function for 1-3/16 inch to 2 inch doors. The Delaney LP250 is an electronic keypad leverlock at Grade 2.
19) Does the BEST 9K dummy lever need power or wiring for an access control opening?
No. The 9K 1DT is entirely mechanical, no electronics and no wiring, so it goes on the inactive leaf of an access-controlled pair with no door loop and no prep for one. If you need an electrified lever on that opening, a fail safe unit such as the Corbin Russwin CL33903 runs on 12VAC/DC.
20) Does the Corbin Russwin 585F715 lock lever work as a replacement for the BEST 9K 1DT?
It does not. The Corbin Russwin 585F715 is a Grade 1 lock lever for the ED8000 pushpad exit device and the CL3300 cylindrical lock series, a trim lever that goes onto those specific devices for 1-3/4 inch to 2 inch doors. The BEST 9K 1DT is complete single dummy trim mounted directly to the door face on an inactive or non-latching leaf, not a lever component for an exit device.
21) What is the difference between the BEST 9K 1DT and the Accentra 5301LN or 4601LN Augusta levers?
Trim design is shared in name only. The Accentra 5301LN and 4601LN both carry the Augusta trim and both are Grade 2 passage, hall, and closet function levers, in the 5300 Series and 4600 Series respectively, so each retracts a latch. The BEST 9K 1DT is Grade 1 dummy trim with no latch. If you want the Augusta look at Grade 1 in a dummy, the 455LN Augusta is the one that matches function.
