Accentra AU-455LN-626 – Frequently Asked Questions

1) Is the Accentra 455LN a working lever or just a pull?
It's a single dummy, so the lever is fixed and there is nothing behind it. No latch, no cylinder, no turning function. It is a pull/push trim used on an inactive leaf of a pair, a closet or cabinet door, or on the back side of a door where you want the look to match but no latching. If the opening needs to latch, order a passage or keyed function in the same 5400 Series instead.
2) Will the 455LN dummy lever match the other Augusta levers already on my doors?
Yes, if the other openings are Accentra 5400 Series with the Augusta (LN) lever design. The 455LN uses the same Augusta lever and rose, so a dummy on an inactive leaf reads identically to the latching functions next to it. Match the finish code as well, and the trim is visually consistent across the suite.
3) What door thickness does the Accentra 455LN Augusta lever fit?
The 5400LN cylindrical locks adjust from 1-3/4 inches up to 2-1/4 inches. That covers standard commercial 1-3/4 inch doors and the thicker hollow metal and wood doors you see on institutional openings. On doors thinner than 1-3/4 inches, look at a lever rated down to 1-3/8, such as the Falcon K101 (1-3/8 to 2-1/4 inches) or the Dexter C1000 passage (1-3/8 to 1-3/4 inches).
4) Can I use the 455LN on a fire-rated door?
The 5400LN cylindrical locks are UL/cUL fire rated up to 3 hours. Used as dummy trim on the inactive leaf of a fire-rated pair, that rating is what your AHJ will want to see on the hardware schedule. Note the dummy itself does no latching, so the leaf still needs its own approved latching or flush bolt arrangement to satisfy the rating.
5) What is the closest Grade 1 commercial equivalent to the Accentra 455LN Augusta single dummy lever?
The BEST 9K Series 1DT is the nearest match: a Grade 1, heavy duty, non-keyed single dummy trim cylindrical lever lock, the same function and duty class as the Accentra 455LN Augusta, which is a Grade 1 dummy cylindrical leverset. Both are pull-only trim with no latch, so either can be used on the inactive leaf of a pair or on a closet door where the door is held by a ball catch or magnetic catch.
6) Is there a lighter-duty dummy lever if the Accentra 455LN Grade 1 is more than the opening needs?
Yes. The BEST 7KC Series 1DT is a Grade 2, medium duty single dummy trim cylindrical lever, and the Callan Bentley BN5051 is a Grade 2 dummy lever. Both provide the same pull-only trim function as the Accentra 455LN Augusta but at a lower ANSI/BHMA grade and duty rating, which suits low-traffic closet and pantry doors rather than the commercial corridor traffic the Grade 1 455LN is built for.
7) Is the Accentra 455LN Augusta a substitute for a storeroom or classroom lever?
No. The 455LN Augusta is non-keyed dummy trim with no latch or cylinder. For a keyed opening, the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt, the Cal-Royal AG03 is a Grade 2 classroom lever with a 6-pin Schlage C keyway and 2-3/4 inch backset, and the Dexter C1000 classroom is a Grade 1 keyed clutching classroom lever. A dummy is often ordered alongside these to trim the inactive leaf of a pair.
8) Does the 455LN dummy lever need to be handed?
No handing to specify. The 5400LN locks are non-handed and reversible, so one part number works on a left or right hand door. That's a difference from some decorative dummies, like the Baldwin Estate 5103 half dummy, which is ordered as a specific left hand or right hand part.
9) Is a Grade 1 dummy lever worth it over a Grade 2 dummy?
For high-traffic commercial and institutional openings, yes. The 455LN is certified to ANSI/BHMA A156.2 Series 4000 Grade 1, which is the top operational grade for bored locksets, and it is built on a heavy-gauge steel, zinc-plated dichromated mechanism. A dummy gets pushed and pulled hard on inactive leaves in schools and hospitals, and the rose mounting is what fails first on lighter trim. If the door is low-traffic, the BEST 7KC Series 1DT single dummy is a Grade 2, medium duty alternative; the BEST 9K Series 1DT is another Grade 1, heavy duty single dummy lever.
10) Do I need to order a strike or latch with a 455LN single dummy?
No. A single dummy is trim only, so there is no latch, no strike, and no cylinder or keys to specify. Prep is just the rose mounting on one face, not a full 2-1/8 inch cross bore and 2-3/4 inch backset like the latching functions in the 5400 Series take. If you are ordering the active leaf at the same time, that one is where the backset, latchbolt throw and strike lip length decisions come in.
11) I need a matching pair of dummy levers for a double door. Can I get both sides?
The 455LN is a single dummy, one lever for one face. For two faces you order two. If you'd rather buy it as a set, Emtek supplies dummy leversets in pairs, such as the Arts and Crafts and Cortina levers, though those are decorative brass trim rather than a Grade 1 commercial lever.
12) Which Grade 1 passage lever pairs best with the Accentra 455LN dummy on a pair of doors?
For the active leaf, Grade 1 passage options include the Falcon K101, heavy duty, fire rated, with non-handed levers, the Falcon T101 heavy duty passage with pressure release technology, and the Corbin Russwin CL3110 vandal resistant passage/closet lever. The Accentra 455LN Augusta on the inactive leaf is likewise Grade 1 and non-handed, so the pair matches in grade; confirm lever style and finish to keep the two leaves visually consistent.
13) Do I need to specify handing when substituting a Baldwin or Emtek dummy lever for the Accentra 455LN Augusta?
Yes, with the Baldwin. The Accentra 455LN Augusta is non-handed and ships as a single dummy. The Baldwin Estate 5103 half dummy with 5048 rose is ordered by hand, 5103-LDM for left and 5103-RDM for right, so you must confirm the swing before ordering. Emtek dummy leversets such as the Arts and Crafts and Cortina dummies are supplied as pairs, which covers both faces of a single door rather than one side.
14) My door is 2 inches thick. Which lever locks besides the Accentra 455LN will cover it?
The Accentra 455LN Augusta adjusts from 1-3/4 inch to 2-1/4 inch, the widest range among comparable commercial leversets. If you need a latching lock at that thickness, the Falcon K101 covers 1-3/8 inch to 2-1/4 inch and the Corbin Russwin CL3110 covers 1-3/4 inch to 2 inch. The Dexter C1000 passage and the Hager 2510 stop at 1-3/4 inch and 2 inch respectively, so check the exact slab before substituting.
15) What is the difference between the Accentra 455LN Augusta dummy and the Emtek or Baldwin decorative dummy levers?
The Accentra 455LN Augusta is a commercial Grade 1 cylindrical dummy with a heavy-gauge steel mechanism, UL/cUL fire rating up to 3 hours, and 13 finishes including PVD options. The Baldwin Estate 5103 half dummy with 5048 rose and the Emtek Cortina and Arts and Crafts dummy pairs are residential-style decorative trim sold by lever design and hand or as pairs. Choose the Accentra where a commercial finish schedule and grade certification govern the opening.
16) Can the Accentra 455LN Augusta be used where a keyless pushbutton lever is specified?
No. The 455LN Augusta is a non-keyed dummy with no access control. For keyless mechanical entry, the Lockey 2835 pushbutton keyless lever lock is ADA compliant with a passage function and fits 1-3/16 inch to 2 inch doors, and the Lockey 1150 heavy duty mechanical keypad lever set has an adjustable backset and covers 1-1/8 inch to 2 inch. The Delaney LP250 is a Grade 2 electronic keypad leverlock.
17) Is a Kwikset or Callan passage lever an acceptable substitute for the Accentra 455LN on a commercial opening?
They serve a different market. The Kwikset 200BRNL Breton passage and Callan Asheville AH5011 passage are Grade 3 leversets, and the Kwikset 200BRNL fits 1-3/8 inch to 1-3/4 inch doors. The Accentra 455LN Augusta is ANSI/BHMA A156.2 Series 4000 Grade 1 and adjusts to 2-1/4 inch. Where a project specification calls out Grade 1 commercial hardware, a Grade 3 residential lever will not meet it.
18) What finishes does the Accentra 455LN Augusta dummy lever come in?
Nine finish choices to order: 605 Bright Brass, 606 Satin Brass, 612 Satin Bronze, 613E Dark Oxidized Satin Bronze equivalent, 619 Satin Nickel, 625 Bright Chrome, 626 Satin Chrome, plus BSP Black Suede and WSP White Suede powder coat. PVD is standard on 605 and 606, which is what you want on exterior or high-humidity openings where a lacquered brass would break down.
19) Is the Accentra 455LN approved for windstorm openings?
The 5400LN series carries windstorm certification, which matters on shelter and storm-rated openings in coastal and tornado-region facilities. Local code governs the assembly, so verify the full door, frame and hardware combination against your jurisdiction's requirement rather than the lock alone.
