Accentra YAL-AU-6406LN-626 – Frequently Asked Questions

1) What does the service station function on the Accentra 6406LN Augusta lever lock actually do?
Service station is a keyed single-cylinder function on the 6406LN Augusta cylindrical lever. It uses a guardbolt that deadlocks the latchbolt whenever the door is closed, and the cylinder is a brass 6-pin keyed-random unit with two keys supplied. Handing has to be specified, so it is not a lock you can flip in the field.
2) Will the Accentra 6406LN fit a 1-3/8 inch door?
No. The 6406LN Augusta lever is built for 1-3/4 inch doors only, with no adjustment range. On a 1-3/8 inch interior door you need a lockset that covers the thinner leaf, such as the Dexter C1000 Series, which lists 1-3/8 to 1-3/4 inches, or the Falcon K101, which covers 1-3/8 to 2-1/4 inches.
3) Does the 6406LN lever lock use a 2-3/8 or 2-3/4 inch backset?
The Augusta 6406LN is a 2-3/4 inch backset lockset. That is the standard commercial bore spacing, so it drops into a door prepped for 2-3/4 without moving the cross bore. If your existing prep is 2-3/8, this is the wrong part for that door.
4) Do I have to specify handing when ordering the Accentra Augusta 6406LN?
Yes. Handing must be specified for all functions and designs in this line, so the 6406LN is not field reversible. Get the swing right off the door before you order. The strike is the one reversible piece, so that part will not trip you up.
5) Will the 6406LN latch into my existing strike?
The latchbolt is stainless steel with a 1/2 inch throw, and the lock ships with a 1-1/4 inch lip ANSI strike. If your frame already has an ANSI strike prep, it lines up. Other lip lengths and strike types can be ordered when the frame or a deep stop requires a longer lip.
6) Is the Accentra 6406LN Augusta lever rated for fire doors?
It carries a UL-cUL fire rating up to 1-1/2 hours and is ANSI/BHMA Grade 1 certified. That combination is what gets it approved on labeled openings in schools, hospitals and office corridors.
7) I need a Grade 1 storeroom lever instead of a service station function - what should I order?
The Accentra 6406LN Augusta is a service station function lever, so it is not the right pick if you need a key-retracted storeroom opening. For a storeroom function lever, the Cal-Royal AG05 is a Grade 2 storeroom lockset with a deadlocking latchbolt, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever. Both are storeroom function rather than service station, so confirm the function code on your door schedule before you commit.
8) What is the closest Grade 1 heavy duty cylindrical lever if I do not need a keyed function on that door?
The Accentra 6406LN Augusta is a keyed single-cylinder lever. For a non-keyed opening at the same Grade 1 heavy duty level, the Falcon K101 is a Grade 1 passage cylindrical lock with non-handed levers, fire rated, and rated for 1-3/8 inch to 2-1/4 inch doors, and the Falcon T101 is a Grade 1 heavy duty passage lever. Corbin Russwin CL3110 is another Grade 1 passage option, vandal resistant and fire rated for 1-3/4 inch to 2 inch doors.
9) My doors are 2 inches thick - the Accentra 6406LN will not fit, so what else works?
The Accentra 6406LN Augusta is built for 1-3/4 inch doors only, so a 2 inch door needs a different lockset. Corbin Russwin CL3110 covers 1-3/4 inch to 2 inch and is a Grade 1 passage lock; Dexter C1000 asylum function covers 1-3/8 inch to 2 inch at Grade 1; Falcon K101 covers 1-3/8 inch to 2-1/4 inch at Grade 1. Match the function you need before choosing among them, since these are passage, asylum, and passage respectively.
10) I need a classroom or classroom security function lever rather than the Accentra 6406LN - what are my options?
The Accentra 6406LN Augusta is a service station function and will not serve a classroom opening. Dexter C1000 is offered in a Grade 1 classroom clutching keyed lever and a Grade 1 classroom security version, both for 1-3/8 inch to 1-3/4 inch doors. Cal-Royal AG03 is a Grade 2 classroom lever with a 6-pin Schlage C keyway keyed different and a 2-3/4 inch backset, which matches the 6406LN backset if you are working to existing door prep.
11) We key everything to Schlage C - the Accentra 6406LN ships keyed random, so what matches our system?
The Accentra 6406LN Augusta comes with a brass 6-pin keyed-random cylinder and two keys as standard, with 7-pin available to order. If the facility is standardized on the Schlage C keyway, the Cal-Royal AG03 classroom lever and AG00 entrance lever both use a 6-pin Schlage C keyway keyed different, and the Arrow MK33-BD-CS uses a conventional cylinder in the Schlage C keyway. The AG03 shares the 2-3/4 inch backset, while the AG00 is a 2-3/8 inch backset for 1-3/8 inch to 1-3/4 inch doors.
12) What finish does the Augusta 6406LN come in?
626 satin chrome, and that is the only finish offered on this lock. If your building standard is oil rubbed bronze or satin brass, this model will not match it.
13) Can I get the 6406LN with 7-pin cylinders or lead shielding for an x-ray room?
Both are order options on the Augusta 6406LN. The standard build is a brass 6-pin keyed-random cylinder with two keys, and 7-pin cylinders can be specified instead if your facility masterkeys on a 7-pin system. Lead shielding is also available to order for radiology openings.
14) I need a Grade 1 lever in a different function for the rest of my openings. What else is there?
For a matching duty level in other functions, the Corbin Russwin CL3110 is a Grade 1 fire rated passage/closet lever for 1-3/4 to 2 inch doors, the Dexter C1000 Series covers Grade 1 classroom, classroom security and asylum functions, and the Corbin Russwin CL33903 is the Grade 1 fail safe electrified lever at 12VAC/DC when an opening needs access control.
15) Is a Grade 2 lever like the Hager 2525 an acceptable stand-in for the Accentra 6406LN?
They are not the same duty rating. The Accentra 6406LN Augusta is ANSI/BHMA Grade 1 with a heavy-gauge steel mechanism and a UL-cUL fire rating up to 1-1/2 hours. The Hager 2525 is a Grade 2 commercial cylindrical entry lock for 1-3/8 inch to 2 inch doors, and the Falcon B511CP6D is a Grade 2 medium duty entry/office lever. If your spec calls out Grade 1, those Grade 2 units will not satisfy it, though they cover a wider door thickness range.
16) For a behavioral health or utility room where the lever must not trap anyone, is the Accentra 6406LN the right lock?
No - the Accentra 6406LN Augusta is a keyed service station lever, not an asylum function. For asylum, institution, and utility openings, the Dexter C1000 asylum (F87) is a Grade 1 cylindrical lock for 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is a Grade 2 heavy duty asylum lock with a conventional cylinder in the Schlage C keyway, though that one uses a ball knob rather than a lever.
17) Can I use a dummy trim in place of the Accentra 6406LN on an inactive leaf?
A dummy trim has no latch at all, so it is only correct on a leaf that never latches - it is not a substitute for the keyed, latching Accentra 6406LN Augusta. For that inactive leaf, the BEST 9K Series 1DT is a Grade 1 non-keyed heavy duty single dummy trim lever, and the BEST 7KC Series 1DT is the Grade 2 medium duty equivalent. Pair the dummy on the inactive leaf with the 6406LN on the active one if the opening calls for it.
18) We want keypad access on that door instead of keys - what replaces the Accentra 6406LN?
The Accentra 6406LN Augusta uses a brass 6-pin keyed-random cylinder with two keys, so going keyless means a different platform. The Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function and ADA compliance for 1-3/16 inch to 2 inch doors, the Lockey 2835DC adds a double combination, and the Lockey 1150 is a heavy duty mechanical keypad lever set for 1-1/8 inch to 2 inch doors. The Delaney LP250 is an electronic keypad leverlock at Grade 2 if you want an electronic rather than mechanical keypad.
19) Can I get the same Grade 1 lever with electric access control instead of the Accentra 6406LN?
The Accentra 6406LN Augusta is a mechanical cylindrical lever with no electrified option. For an access-controlled opening, 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, available with the NZ lever and D rose. That covers the same 1-3/4 inch door the 6406LN is built for, with the power and fail safe behavior the mechanical lock cannot provide.
20) Is a Kwikset or Master Lock residential lever an equivalent to the Accentra 6406LN?
No. The Accentra 6406LN Augusta is ANSI/BHMA Grade 1 for commercial use with a UL-cUL fire rating up to 1-1/2 hours. The Kwikset 200BRNL Breton passage lever is Grade 3 for 1-3/8 inch to 1-3/4 inch doors, the Kwikset 300BRNL Breton privacy lever is Grade 3 in the same range, and the Master Lock RL01 return style keyed entry lever is Grade 3 entrance function. Those are residential-duty and non-fire-rated by comparison, so they do not carry a Grade 1 commercial spec.
21) I need a privacy lever for a restroom, not the keyed Accentra 6406LN - what should I use?
The Accentra 6406LN Augusta is a keyed single-cylinder service station lever and is not a privacy set. For bed and bath privacy, the Hager 2540 is a Grade 2 privacy cylindrical lock with the Withnell lever for 1-3/8 inch to 2 inch doors, and the Baldwin Estate 5103 privacy lever with 5048 rose covers the decorative side. The Arrow MK02-TA is a privacy cylindrical lock with a fire rating for 1-3/4 inch to 2 inch doors if you need privacy on a rated opening, though it uses a Tudor knob rather than a lever.
22) Handing has to be specified on the Accentra 6406LN - is there a non-handed alternative?
Handing must be specified for all functions and designs on the Accentra 6406LN Augusta. If you would rather stock a non-handed lock, the Falcon K101 is a Grade 1 passage cylindrical lock with non-handed levers and the Falcon B101 is a Grade 2 medium duty passage lever, also non-handed. Both are passage rather than keyed service station, so they apply where the door does not need a cylinder.
23) Is the Augusta 6406LN suitable for a house or apartment interior door?
It is a commercial lockset, sold in satin chrome only on a 2-3/4 inch backset for 1-3/4 inch doors. Residential interior doors are usually 1-3/8 inch with a 2-3/8 backset, so a Grade 3 residential lever like the Kwikset 200BRNL Breton passage set, rated 1-3/8 to 1-3/4 inch, is the closer fit for that work.
24) Does the 6406LN arrive assembled or do I build it up on the job?
The Augusta 6406LN is a preassembled cylindrical lockset. Prep the door to the template for the 2-3/4 inch backset, mount it, then check that the guardbolt is engaging against the strike so the latch deadlocks when the door closes.
25) The Accentra 6406LN only comes in 626 satin chrome - what if I need brass or nickel?
The Accentra 6406LN Augusta is offered in 626 satin chrome only. If the opening calls for a different look, the Bravura Miramar passage leverset is a Grade 2 unit in US4 satin brass and the Callan Asheville is a Grade 3 passage leverset in satin nickel. Note that both are passage function and lower grade than the 6406LN, so they suit decorative interior doors rather than a Grade 1 keyed commercial opening.
