Accentra AU-455LN-D-626 – Frequently Asked Questions

1) Will the Accentra 455LN-D fit a 2 inch thick door?
Yes. The 455LN-D Augusta dummy trim is adjustable for door thickness from 1-3/4 inches up to 2-1/4 inches, so a 2 inch door is inside the range. It will not suit a 1-3/8 inch door, which is common on older interior openings; for that thickness you need a set rated down to 1-3/8, such as the Falcon K101 Grade 1, listed at 1-3/8 to 2-1/4 inches.
2) Can I use the 455LN-D on a fire rated door?
The 5400LN Series carries a UL/cUL fire rating up to 3 hours and is ANSI/BHMA A156.2 Series 4000 Grade 1. On a fire rated pair, the dummy trim goes on the inactive leaf while the fire rating of the assembly depends on the latching hardware (flush bolts or a fire exit device) being rated as well.
3) Do I need a strike or a latch with a double dummy lever?
No strike and no latch. Because the 455LN-D has no operating mechanism, the door prep is for the through-bolted trim only, and you supply whatever holds the door shut: a ball or roller catch, magnetic catch, or flush bolts on an inactive leaf. Backset only matters here for lining the lever up with the other doors, and the 5400LN Series standard is 2-3/4 inches.
4) The door needs to latch, not just have a lever pull. What should I order instead of the 455LN-D?
A dummy lever has no latch at all, so if the door must stay closed you need a passage function. In Grade 1 cylindrical, the Falcon K101 is a heavy duty passage lever that fits doors 1-3/8 inch to 2-1/4 inch and is fire rated, the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage lever for 1-3/4 inch to 2 inch doors, and the Dexter C1000 passage is a Grade 1 clutching passage lever. Any of those replaces the Accentra 455LN-D Augusta where a working latchbolt is required.
5) I need a lever on an office door that locks. Is the 455LN-D the wrong pick?
Yes, for any locking application. The Accentra 455LN-D Augusta is non-keyed dummy trim with no cylinder and no latch. For a keyed office or entrance lever, the Falcon B511CP6D is Grade 2 entry/office, the Hager 2525 is a Grade 2 commercial entry lever for 1-3/8 inch to 2 inch doors, and the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt. Choose by whether the lever should be lockable from inside or always locked outside.
6) Do I have to specify handing when ordering the Augusta 455LN-D dummy lever?
No handing to call out. The 5400LN Series is non-handed and reversible, and a double dummy has a fixed lever on each face anyway, so one part number covers left and right hand openings.
7) Should I get a double dummy or a single dummy lever?
Double dummy, like the Accentra 455LN-D, puts a fixed lever on both faces and is what you want on an inactive leaf of a pair or a closet door people pull from either side. A single dummy is one lever on one face only, for a door you only ever pull from the corridor side. ZenSupply carries single dummy trim as well, including the BEST 9K Series 1DT in Grade 1 heavy duty and the medium duty Grade 2 BEST 7KC Series 1DT.
8) Is the 455LN-D keyed, and can I add a cylinder later?
No. The Augusta 455LN-D is non-keyed dummy trim with no cylinder and no latch, and it cannot be converted to a locking function. If you need the same Augusta lever and finish but with key control on that opening, order the keyed function from the 5400LN Series instead.
9) Are there decorative dummy lever pairs as an alternative to the Accentra Augusta 455LN-D?
Emtek offers dummy pairs in its Arts and Crafts line, including the Arts and Crafts lever and the Hammered lever, plus the Classic Brass Cortina lever dummy pair. Like the Accentra 455LN-D Augusta, these supply lever trim on both faces with no latch. The Accentra is a commercial Grade 1 cylindrical lockset with a UL/cUL fire rating up to 3 hours; the Emtek pairs are residential-styled decorative trim, which is the distinction to weigh on a hospitality or lobby opening versus a rated commercial one.
10) Is there a lighter duty dummy lever if the opening does not need Grade 1?
Yes. The BEST 7KC Series 1DT is a medium duty Grade 2 single dummy trim cylindrical lever, and the Callan Bentley BN5051 is a Grade 2 dummy lever. Both are non-keyed dummy trim like the Accentra 455LN-D Augusta, but the 455LN-D is Grade 1 and covers both door faces as a double dummy. For closet or decorative inactive leaves in light traffic, the Grade 2 options carry the same function at a lower duty rating.
11) Which dummy levers look like substitutes for the Accentra 455LN-D but are handed?
The Baldwin Estate 5103 half dummy comes as a dedicated left hand version and a dedicated right hand version, so you must specify the door swing when ordering. The Accentra 455LN-D Augusta is non-handed, which means one part number works on either hand and you do not carry two SKUs for a stocking program. If you are matching a Baldwin Estate opening, order the 5103-LDM or 5103-RDM to suit the hand.
12) Can I use a privacy lever where the 455LN-D dummy was specified on a restroom door?
No. The Accentra 455LN-D Augusta is dummy trim and provides no privacy locking. For a bed or bath opening, the Hager 2540 with the Withnell lever fits 1-3/8 inch to 2 inch doors, the Baldwin Estate 5103 privacy lever with 5048 rose is the decorative option, and the Kwikset 300BRNL Breton is a Grade 3 privacy lever for 1-3/8 inch to 1-3/4 inch doors. Match the grade to the traffic the restroom sees.
13) If I am standardizing a building on one lever family, what keyed functions pair with the Accentra 455LN-D dummy?
The 455LN-D Augusta covers inactive leaves only, so a standardization package needs keyed functions alongside it. In Grade 1 cylindrical, the Dexter C1000 series spans classroom, classroom security, and asylum functions, and the Corbin Russwin CL33903 is a Grade 1 fail safe electrified lever at 12V AC/DC for openings tied to access control. Specifying one lever design across those functions keeps the visual match while the dummy handles the non-latching doors.
14) What is a lighter duty alternative to the Accentra 455LN-D dummy lever?
For lower traffic work where Grade 1 is not required, the Callan Bentley dummy lever is a Grade 2 option, and Emtek offers decorative dummy pairs including the Arts and Crafts and Hammered levers and the Classic Brass Cortina. Those are residential and light commercial trim; the 455LN-D is the Grade 1 commercial choice when the dummy has to match Grade 1 hardware elsewhere in the building.
15) Is this lever suitable for a school or hospital corridor door?
Yes for the inactive or non-latching leaves in those buildings. The 5400LN Series is built for commercial duty with a heavy-gauge steel, zinc-plated and dichromated mechanism, holds ANSI/BHMA A156.2 Series 4000 Grade 1, and is windstorm certified subject to local code. Educational, healthcare, government and multi-tenant residential are the intended settings.
