Accentra AU-5409LN-626 – Frequently Asked Questions

1) Will the Accentra 5409LN Augusta lever lock fit a 2 inch thick door?
Yes. The 5409LN Augusta cylindrical lever adjusts from 1-3/4 inch through 2-1/4 inch door thickness, so a 2 inch door is inside the standard range with no special order. Note the low end: it starts at 1-3/4 inches, so a 1-3/8 inch older interior door is below what this lock covers. For that thickness the Falcon K101 covers 1-3/8 to 2-1/4 inches and the Dexter C1000 Entry/Office covers 1-3/8 to 1-3/4 inches.
2) What backset does the Accentra 5409LN come with, and can it be used on a 5 inch backset door?
Standard is 2-3/4 inch backset, which is the usual commercial bore location. For deeper stiles, a 3-3/4 inch or 5 inch extension link is available to order, so a wide-stile or unusual prep is covered, but it has to be specified when the order is placed rather than adjusted in the field.
3) Will the 5409LN latch into the strike that is already in my frame?
The latchbolt throws 1/2 inch in stainless steel as standard, with a 3/4 inch throw available to order. The standard strike shipped is a 1-1/4 inch curved lip sized for a 1-3/4 inch door, and other lip lengths can be ordered. If your existing frame has an ANSI strike or a deep reveal that needs more bite, order the 3/4 inch throw. All strikes are reversible, so the existing frame handing does not matter.
4) Do I need to specify handing when I order the Accentra 5409LN Augusta lever?
No handing to specify. The 5409LN is non-handed and reversible, and the strike is reversible too, so one part number covers left and right hand openings. That is the reason it works well for a property manager stocking a spare for a building with doors swinging both ways.
5) Can the Accentra 5409LN be installed on a fire rated door?
It is UL/cUL fire rated up to 3 hours and carries ANSI/BHMA A156.2 Series 4000 Grade 1. It is also windstorm certified, subject to local code. The guardbolt deadlocks the latchbolt when the door closes, which is standard on all locking functions in the series and is what keeps the latch from being carded on a rated opening.
6) What cylinder and keys come with the Accentra 5409LN, and can I key it into my building's system?
A brass 6-pin keyed-random cylinder with two keys is furnished standard. A 7-pin cylinder is available to order, and other cylinder and keying options (including keyed alike and master keyed setups) are order options rather than field changes. If you are standardizing a building, specify the keying at order time; keyed random means each lock ships on its own key otherwise.
7) I need the lever to release electrically on a fire alarm. What replaces a mechanical exit lever lock?
The Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever lock running on 12VAC/DC for a 1-3/4 inch to 2 inch door, offered with the NZ lever and D rose and in a keyed 12VAC/DC version. Fail safe means the lever unlocks when power drops, which is what an access control or alarm release sequence needs. The Accentra 5409LN Augusta is a purely mechanical exit function lockset with no electrical connection, so it cannot be tied into an access control panel.
8) What is the closest Grade 1 cylindrical lever lock to the Accentra 5409LN Augusta if I need a different lever style?
The Falcon T101 and Falcon K101 are both Grade 1 heavy duty cylindrical lever locks, and the Corbin Russwin CL3110 is a Grade 1 cylindrical lever lock rated for a 1-3/4 inch to 2 inch door. All three sit at the same ANSI/BHMA Grade 1 level as the 5409LN Augusta, which carries a Grade 1 rating with a 2-3/4 inch backset and 1/2 inch stainless steel latchbolt throw. The difference is function: the 5409LN is an exit function lockset, while the T101, K101 and CL3110 are passage locks with no cylinder. If the opening needs free egress with no keyed outside trim, they cross over closely; if a key must operate the outside lever, they do not.
9) Can I use a Grade 2 lever lock instead of the Accentra 5409LN Augusta on a lower traffic door?
The Hager 2580 storeroom lever with the Withnell design and the Cal-Royal AG05 storeroom leverset are both Grade 2 cylindrical locksets, and the Falcon B511CP6D is a Grade 2 medium duty entrance/office lever. The Accentra 5409LN Augusta is Grade 1 and carries a UL/cUL fire rating up to 3 hours with a guardbolt that deadlocks the latchbolt when the door closes. The Grade 2 options are built to a lighter cycle standard, so they suit interior offices, storage rooms and low-traffic tenant doors, while the 5409LN is aimed at doors seeing continuous daily use. Door thickness also narrows: the Hager 2580 covers 1-3/8 inch to 2 inch and the Cal-Royal AG05 covers 1-3/8 inch to 1-3/4 inch, against 1-3/4 inch to 2-1/4 inch on the 5409LN.
10) I need a Grade 1 lever lock for a classroom or an office rather than an exit door. What should I order?
The Dexter C1000 series covers those functions at the same Grade 1 level as the Accentra 5409LN Augusta: the C1000 classroom lever is a keyed clutching Grade 1 lock, the C1000 classroom security lever adds classroom security function, and the C1000 entry/office lever handles the office opening, all listed for 1-3/8 inch to 1-3/4 inch doors. The 5409LN is built for the exit function with a 2-3/4 inch backset and 1-3/4 inch to 2-1/4 inch door thickness range. Match to the door's role: an exit function lockset does not give a teacher the inside keyed lockdown a classroom security lever provides.
11) What can I put on a 2-1/4 inch thick door if the lever lock I am looking at only covers 2 inch?
The Accentra 5409LN Augusta adjusts from 1-3/4 inch to 2-1/4 inch, and the Falcon K101 Grade 1 heavy duty passage lock is listed for 1-3/8 inch to 2-1/4 inch. Most of the surrounding cylindrical levers stop short of that: the Corbin Russwin CL3110 and CL33903 cover 1-3/4 inch to 2 inch, the Hager 2510 and 2525 cover 1-3/8 inch to 2 inch, and the Design Hardware X75 is listed for 1-3/4 inch only. On thick fire doors or older solid core stock measure the leaf before ordering, because the door thickness range is what rules a lockset in or out.
12) Which alternatives to the Accentra 5409LN Augusta are fire rated for a rated opening?
The Falcon K101 Grade 1 passage lock and the Corbin Russwin CL3110 Grade 1 passage lock are both fire rated, and the Arrow MK02-TA privacy lock is fire rated as well. The Accentra 5409LN Augusta is UL/cUL fire rated up to 3 hours and is also windstorm certified subject to local codes, with lead shielding available to order for radiology and similar rooms. For a rated corridor or stair door, confirm the label hours the opening requires against the lockset before you order.
13) What does the exit function on the 5409LN actually do at the door?
Exit function means free egress from the inside at all times with no key needed on the way out, which is why it lands on stairwell, corridor and back-of-house doors in commercial and industrial buildings. It is a cylindrical bored lockset in the Accentra 5400 Series with the Augusta lever, built on a heavy gauge steel, zinc plated and dichromated mechanism. If you need a different behaviour on the opening, that is a different function number in the same series, not an option on this one.
14) What finishes does the Accentra 5409LN Augusta lever come in?
Nine finishes are orderable: 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 black suede powder coat (BSP) and white suede powder coat (WSP). PVD is standard on 605 and 606, which is what keeps a bright brass lever from tarnishing in an exterior or high-traffic corridor. 626 satin chrome is the usual match if the rest of the building is on commercial hardware.
15) Can I get a flat front instead of the beveled front on the 5409LN?
The front is 2-1/4 x 1-1/8 inches beveled as standard, and flat fronts are available to order. Lead shielding is also an order option, which matters for radiology and imaging suites in a healthcare facility. Both are specified at order, not swapped later.
16) What is the difference between the Accentra 5409LN and a Grade 2 lever lock for a commercial corridor?
The 5409LN is ANSI/BHMA A156.2 Series 4000 Grade 1, the top cycle and strength tier, which is what a school corridor or a warehouse door goes through. Grade 2 levers like the Hager 2525 entry or the Falcon B511CP6D entry/office are medium duty and sit on lower-traffic openings. If you want Grade 1 but a non-keyed opening, the Falcon K101 passage and the Corbin Russwin CL3110 passage/closet are both Grade 1 cylindrical levers.
17) Is a cylindrical lever lock like the 5409LN the right choice, or should I be looking at an exit device?
A bored cylindrical lockset like the 5409LN mounts in a standard two-hole door prep and handles a single leaf where a lever is enough for egress. Once the opening is a rated exit with occupant load requiring panic hardware, or a pair of doors, you are into exit device territory instead. Accentra covers that with the 6000 Series and the 7000 Series exit devices, and lever trim for a pushpad device is a separate part such as the Corbin Russwin 585F715 lock lever for the ED8000 pushpad.
18) Is the Accentra 5409LN the same lock as the Yale 5409LN?
Same lock. Yale Commercial's lever lock line was rebranded as Accentra under ASSA ABLOY, and the 5400LN Series carries over unchanged, model 5409LN with the Augusta lever. If your building's records or an old spec list a Yale 5409LN Augusta, this is the current part for it.
19) What Grade 1 lever lock should I use for a psychiatric or detention type room instead of the Accentra 5409LN?
The Dexter C1000 asylum lock, function F87, is a Grade 1 cylindrical lock for 1-3/8 inch to 2 inch doors and is the function built for asylum, institution and utility openings. The Arrow MK33-BD-CS is also an asylum/institution/utility lock, heavy duty with a conventional cylinder in Schlage C keyway, though it is Grade 2 and uses a ball knob rather than a lever. The Accentra 5409LN Augusta is an exit function lever lock, which controls egress rather than providing the key-both-sides control an asylum function calls for.
20) Is a dummy lever trim the same thing as the Accentra 5409LN Augusta exit lock?
No. The BEST 9K series 1DT single dummy trim is a Grade 1 heavy duty non-keyed lever with no latch mechanism at all, and the BEST 7KC series 1DT is the Grade 2 medium duty equivalent. Dummy trim mounts to the face of the door as a pull only. The Accentra 5409LN Augusta is a working cylindrical lockset with a 1/2 inch stainless steel latchbolt throw and a guardbolt that deadlocks the latch when the door is closed. A dummy trim will not latch an active or inactive leaf that has to hold shut.
21) Can I use a keypad lever set instead of a keyed commercial lever lock to avoid issuing keys?
The Lockey 1150 heavy duty mechanical keypad lever set with double combination and the Lockey 2835DC double combination keyless lever lock both run on a mechanical code with no key and no battery, the 1150 for 1-1/8 inch to 2 inch doors and the 2835 series for 1-3/16 inch to 2 inch doors. The Delaney LP250 is a Grade 2 electronic keypad leverlock and Emtek offers a Classic keypad leverset. The Accentra 5409LN Augusta works from a brass 6-pin keyed-random cylinder with two keys furnished and is UL/cUL fire rated up to 3 hours, so on a rated opening confirm the keypad unit is acceptable before swapping.
22) Which lever locks come with a Schlage C keyway if I am keying into an existing Schlage system?
The Cal-Royal AG00 entrance lever is a Grade 2 lock with a 6-pin Schlage C keyway keyed different and a 2-3/8 inch backset, and the Cal-Royal AG03 classroom lever in the AG series is 6-pin Schlage C keyway keyed different with a 2-3/4 inch backset. The Arrow MK33-BD-CS also uses a conventional Schlage C keyway cylinder. The Accentra 5409LN Augusta ships standard with a brass 6-pin keyed-random cylinder and two keys, with 7-pin available to order, so keying it into an existing system is a cylinder decision made at order time.
23) Is exit device lever trim the same as a cylindrical exit function lever lock?
No, and the distinction decides what you can install. The Corbin Russwin 585F715 is a Grade 1 lock lever for the ED8000 pushpad exit device, and the Imperial USA ED-EL500HD is heavy duty escutcheon lever trim with an entry function. Both are trim that mounts to a panic device already on the door and do nothing on their own. The Accentra 5409LN Augusta is a complete cylindrical lockset with its own latchbolt, guardbolt, strike and cylinder, prepped into a standard cylindrical bore. If the door has a pushpad device, order trim; if it has a 161 cylindrical prep, order the lockset.
24) What lever lock do I use for a bathroom or bedroom door where the 5409LN is not the right function?
The Hager 2540 with the Withnell lever is a Grade 2 privacy cylindrical lock for 1-3/8 inch to 2 inch doors, the Arrow MK02-TA is a privacy cylindrical lock with a Tudor knob and a fire rating, and the Baldwin Estate 5103 privacy lever with the 5048 rose covers the same function in a decorative line. Privacy function locks from the inside with no key outside. The Accentra 5409LN Augusta is an exit function lockset, which is the wrong choice for a bath or bedroom because it does not give the occupant inside privacy locking.
25) Is a non-handed lever lock available across the alternatives, or do I have to specify hand?
The Accentra 5409LN Augusta is non-handed and its strikes are all reversible, so one part covers either swing. The Falcon B101 is a Grade 2 passage lever with a non-handed design and the Falcon K101 is a Grade 1 passage lock with non-handed levers. By contrast the Baldwin Estate 5103 half dummy is sold as a left hand part and a separate right hand part, so the swing has to be confirmed before ordering. On a fleet of doors with mixed swings, non-handed hardware keeps a single line item on the order.
26) If I want a decorative lever on a residential or hospitality interior instead of a commercial lockset, what are the options?
The Baldwin Estate 5103 line pairs a lever with the 5048 rose in passage, privacy and half dummy versions, and Emtek offers the Arts and Crafts lever and Hammered lever as dummy pairs plus the Classic brass Cortina lever dummy pair. The Bravura Miramar, Atlanta, Orlando and Tampa passage leversets are Grade 2 with round or square trim, the Tampa using square trim. The Accentra 5409LN Augusta uses the Augusta lever and is a Grade 1 commercial lockset, so the trade is a decorative appearance against the heavy duty commercial rating.
27) What is the difference between the Design Hardware X75 and J75 passage levers when standardizing a building?
The Design Hardware X75 in the X series is a Grade 1 passage lever lockset with a flat lever for a 1-3/4 inch door, and the J75 in the J series is the Grade 2 passage lever lockset, also flat lever for a 1-3/4 inch door. Same lever appearance, different grade tier. The Accentra 5409LN Augusta is a Grade 1 exit function lockset adjustable from 1-3/4 inch to 2-1/4 inch, so on a building where you want one look across offices and exits, the X75 keeps the passage doors at Grade 1 alongside it while the J75 steps them down.
