Accentra YAL-AU-6405LN-626 – Frequently Asked Questions

1) Will the Accentra 6405LN storeroom lever fit a 1-3/8 inch door?
No. The 6405LN Augusta is built for 1-3/4 inch doors only, with a 2-3/4 inch backset. On a 1-3/8 inch interior door you need a lockset with a range that covers it, such as the Cal-Royal AG05 storeroom lever (1-3/8 to 1-3/4 inch) or the Hager 2580 storeroom lever (1-3/8 to 2 inch), both Grade 2.
2) How does a storeroom function lever actually work day to day?
Storeroom function means the outside lever is always locked. Entry is by key only, and the key does not unlock and leave it unlocked; the inside lever always retracts the latch for free egress. That is why the 6405LN suits stockrooms, closets, mechanical rooms and anywhere you never want the door left on latch. If you need staff to be able to unlock and leave the door on passage, a storeroom lock is the wrong function.
3) Do I have to specify handing when I order the 6405LN Augusta lever lock?
Yes. Handing must be specified for all 6400 Series functions and designs, so you need to know whether the opening is left or right hand before the order goes in. The strike is a different story, all strikes supplied are reversible.
4) Will the 6405LN latch into the strike already in my frame?
The latchbolt is stainless steel with a 1/2 inch throw, and a 1-1/4 inch lip ANSI strike ships with the lock. If your existing frame has an ANSI 4-7/8 inch strike prep, the supplied strike drops in. Other lip lengths and strike types are available to order when the frame or a deep reveal calls for a longer lip.
5) Can I use the Accentra 6405LN on a fire rated door?
Yes. The 6405LN is UL-cUL fire rated up to 1-1/2 hours and carries ANSI/BHMA Grade 1 certification, so it is usable on rated stair, corridor and storage room openings within that rating. The guardbolt deadlocks the latchbolt when the door is closed, which is standard on all locking functions in the series.
6) What cylinder and keys come with the 6405LN, and can I key it into my building master system?
It ships with a brass 6-pin keyed-random cylinder and two keys. Keyed random means each lock gets its own random key combination, so if you are standardizing a facility you will want to specify your keying rather than take stock. A 7-pin cylinder is available to order for systems that need the extra pin.
7) What is a Grade 2 storeroom lever alternative to the Accentra 6405LN Augusta?
Two Grade 2 storeroom levers cover the same function with a lighter duty rating. The Cal-Royal AG05 is a Grade 2 storeroom leverset with a deadlocking latchbolt and fits doors 1-3/8 inch to 1-3/4 inch thick. The Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever and fits doors 1-3/8 inch to 2 inch. The Accentra 6405LN is ANSI/BHMA Grade 1, UL-cUL fire rated to 1-1/2 hours, and is built for 1-3/4 inch doors only, so if your openings vary in thickness the Cal-Royal or Hager range is the practical difference.
8) Which lever lock should I use if the door is thicker than 1-3/4 inches?
The Accentra 6405LN Augusta is built for 1-3/4 inch doors only. For thicker doors, the Falcon K101 is a Grade 1 heavy duty cylindrical lock rated for 1-3/8 inch to 2-1/4 inch doors and is fire rated, and the Corbin Russwin CL3110 is a Grade 1 fire rated cylindrical lever for 1-3/4 inch to 2 inch doors. Both of those are passage function rather than storeroom, so they hold the thickness range but not the keyed storeroom operation the 6405LN provides.
9) What finish does the Augusta 6405LN come in, and will it match my other commercial levers?
626 satin chrome is the only finish offered on the 6405LN. That is the standard commercial satin chrome and it reads as a near match alongside 626/652 hardware; if your building is standardized on 626 you are fine. If your other openings are US26D/626 brushed chrome from other makers the appearance is close, but an exact match across brands is never guaranteed.
10) I need a Grade 1 lever for an X-ray or imaging room. Does the 6405LN have a lead lined option?
Lead shielding is available to order on the 6400 Series, which is what radiology and imaging suite openings require. It is not standard, so it has to be called out on the order.
11) I need the same Grade 1 duty but a classroom or passage function instead of storeroom. What else is there?
The 6405LN is storeroom only. For other functions at Grade 1, the Dexter C1000 Series covers classroom, classroom security, asylum and passage, and Corbin Russwin's CL3110 is a Grade 1 fire rated passage/closet lever for 1-3/4 to 2 inch doors. If the opening needs electrified control, the Corbin Russwin CL33903 is a Grade 1 fail safe lever at 12VAC/DC.
12) I need the same Grade 1 lever on a classroom door instead of a storeroom door - what changes?
The Accentra 6405LN Augusta is a storeroom function lock, where the outside lever is always locked and the key retracts the latch. For a classroom opening, the Dexter C1000 is offered in a Grade 1 classroom function with a clutching keyed lever, and in a Grade 1 classroom security function, both for 1-3/8 inch to 1-3/4 inch doors. Cal-Royal also offers the AG03 classroom lever in its AG Series with a 2-3/4 inch backset, matching the 6405LN backset.
13) What is the non-keyed equivalent for the openings on the same corridor that do not need to lock?
The Accentra 6405LN Augusta is a keyed single cylinder storeroom lock. Where an opening needs latching only, the Grade 1 non-keyed options include the Falcon K101 passage lock with non-handed levers, the Falcon T101 heavy duty passage lever, the Design Hardware X75 passage leverset for 1-3/4 inch doors, and the Dexter C1000 passage lever with a clutching mechanism. For openings needing trim only with no latch, the BEST 9K Series 1DT is a Grade 1 heavy duty single dummy trim.
14) Is a Kwikset or Master Lock lever a substitute for the Accentra 6405LN Augusta?
They serve a different class of opening. The Accentra 6405LN is ANSI/BHMA Grade 1 with UL-cUL fire rating to 1-1/2 hours and heavy-gauge steel construction for commercial use. The Kwikset 200BRNL Breton is a Grade 3 passage lever and the 300BRNL Breton is a Grade 3 privacy lever, both for 1-3/8 inch to 1-3/4 inch doors, and the Master Lock RL Series return-style keyed entry lever is Grade 3. Cal-Royal's AUS00 entrance/office lever is Grade 3 as well. Grade 3 products are built to residential-duty cycle testing, so they are not a like-for-like swap on a commercial storeroom door.
15) What should I use instead of the Accentra 6405LN if the door needs access control or keyless entry?
The Accentra 6405LN Augusta is a mechanical keyed lock with a brass 6-pin cylinder. For electrified control, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever running on 12VAC/DC for 1-3/4 inch to 2 inch doors. For mechanical keyless, the Lockey 2835 pushbutton lever lock is ADA compliant and fits doors 1-3/16 inch to 2 inch, the Lockey 1150 keypad lever set covers 1-1/8 inch to 2 inch with an adjustable backset, and the Delaney LP250 is a Grade 2 electronic keypad leverlock.
16) For a utility or patient room door, is the Accentra 6405LN the right function or is an asylum lock better?
The Accentra 6405LN Augusta is a storeroom function, keyed outside with the inside lever always free. An asylum or institution function keys both sides, which is what some utility and patient-care openings call for. The Dexter C1000 is offered in a Grade 1 asylum F87 function for doors 1-3/8 inch to 2 inch, and the Arrow MK33-BD-CS is a Grade 2 heavy duty asylum lock with a ball knob and a conventional Schlage C keyway cylinder. Choose by whether the inside must also be key-controlled.
17) Do I have to specify handing for the Accentra 6405LN, and is there a non-handed alternative?
Handing must be specified for all Accentra 6405LN Augusta functions and designs. If you want to avoid handing on the order, the Falcon K101 Grade 1 passage lock and the Falcon B101 Grade 2 passage lock both use a non-handed lever design, though both are passage function rather than a keyed storeroom lock.
18) What is the difference between the Accentra 6405LN and an entrance or office function lever?
On the Accentra 6405LN Augusta the outside lever stays locked and only the key releases it, which is why it suits storerooms and closets. An entrance or office function lets the occupant control locking from inside. Comparable entrance-function levers include the Hager 2525 Grade 2 commercial cylindrical entry lock for 1-3/8 inch to 2 inch doors, the Falcon B511CP6D Grade 2 entry/office lever, and the Arrow HK11 turn-pushbutton entrance lock with a conventional cylinder for 1-3/8 inch to 1-3/4 inch doors.
19) Can the Accentra 6405LN be used as exit device trim?
No. The Accentra 6405LN Augusta is a complete bored cylindrical lockset with its own latchbolt and 2-3/4 inch backset, prepped for a 1-3/4 inch door. Lever trim for a pushpad exit device is a separate item: the Corbin Russwin 585F715 is a Grade 1 lock lever for the ED8000 pushpad exit device, and the Imperial USA ED-EL500HD is a heavy duty escutcheon lever trim in entry function for the ED-500 Series. Match the trim to the exit device, not to a cylindrical lock.
20) Is the 6405LN preassembled, or do I build it up on the door?
It comes preassembled as a cylindrical lockset, so installation is door prep at a 2-3/4 inch backset, mount, then adjust and test the lever through its full travel. It fits 1-3/4 inch doors only, so there is no thickness adjustment to set.
21) What is the Monroe lever, and can I get the same lock with a knob instead?
Monroe is the lever design on the 6405LN Augusta, a commercial lever trim that satisfies the push-pull-slide operation building codes want for accessible openings. The 6405LN is a lever only product. If a knob is required for the application, Arrow's cylindrical knob locks cover that, for example the MK33-BD-CS asylum function or the HK11 turn-pushbutton entrance with a ball knob.
22) Is a decorative lever like Emtek, Baldwin, or Deltana an alternative to the Accentra 6405LN?
They are a different product class. The Accentra 6405LN Augusta is a commercial Grade 1 cylindrical storeroom lock with a Monroe lever and a 626 satin chrome finish. Baldwin Estate 5103 is offered in passage, privacy, and left- and right-hand half dummy versions with a 5048 rose; Emtek Classic and Arts and Crafts leversets are offered as dummy pairs; Deltana Manchester, Morant, and Linstead levers are entry function for 1-3/8 inch to 2 inch doors. Those are architectural-trim products without the storeroom keying and Grade 1 commercial rating.
