Accentra YAL-AU-6407LN-626 – Frequently Asked Questions

1) Will the Accentra 6407LN Augusta lever lock fit a 1-3/8 inch door?
No. The 6407LN Augusta is built for 1-3/4 inch doors only, with no adjustment range. On a 1-3/8 inch door you need a lock rated for that thickness, like the Hager 2525 Grade 2 cylindrical entry lock, which covers 1-3/8 to 2 inches, or the Dexter C1000 Classroom at 1-3/8 to 1-3/4 inches.
2) Do I have to specify handing when ordering the Accentra 6407LN?
Yes. Handing must be specified for all 6400 Series functions and designs, so the 6407LN is not field reversible. Pin down whether the opening is left or right hand before the order goes in. The 1-1/4 inch lip ANSI strike that ships with it is reversible, so the strike itself is not the constraint.
3) Will the Accentra 6407LN latch into my existing 2-3/4 inch backset door prep?
The 6407LN is a 2-3/4 inch backset cylindrical lock with a 1/2 inch stainless steel latchbolt throw, so it drops into a standard commercial 161 prep cut at 2-3/4. If your doors are prepped at the 2-3/8 inch backset common on residential and light commercial openings, this is the wrong part.
4) What cylinder and keying comes with the Accentra 6407LN, and can I key it into my building system?
It ships as a single cylinder lock with a brass 6-pin keyed-random cylinder and two keys. Keyed random means each lock arrives on its own random key change, so it is not keyed alike or keyed to an existing system out of the box. A 7-pin cylinder is available to order if your masterkey system runs 7-pin.
5) What is a Grade 2 alternative to the Accentra 6407LN entry lever for a lighter-traffic commercial opening?
The Accentra 6407LN Augusta is a Grade 1 entrance-function cylindrical lever lock. Where the traffic does not justify Grade 1, the Hager 2525 is a Grade 2 commercial cylindrical entry lock with a lever handle covering 1-3/8 inch to 2 inch doors, and the Falcon B511CP6D is a Grade 2 medium duty cylindrical lever with entry/office function. Both are keyed entry levers like the 6407LN, but at the Grade 2 cycle and strength level rather than Grade 1.
6) The 6407LN only fits 1-3/4 inch doors. What Grade 1 lever works on a thicker or thinner door?
The Accentra 6407LN Augusta is built for 1-3/4 inch door thickness only. For Grade 1 cylindrical levers with a wider range, the Falcon K101 covers 1-3/8 inch to 2-1/4 inch, the Dexter C1000 asylum function covers 1-3/8 inch to 2 inch, and the Corbin Russwin CL3110 covers 1-3/4 inch to 2 inch. Note that the K101, CL3110 and C1000 asylum are not entrance-function keyed locks, so confirm the function matches the opening before substituting.
7) I need a non-keyed lever to match the 6407LN on interior doors. What pairs with it?
The Accentra 6407LN Augusta is a keyed single-cylinder entrance lever, so it is not the right part for a closet or corridor door. Grade 1 non-keyed cylindrical levers include the Falcon K101 passage, the Falcon T101 heavy duty passage, the Dexter C1000 passage with clutching levers, the Corbin Russwin CL3110 passage/closet, and the Design Hardware X75 passage for 1-3/4 inch doors. For a door leaf that needs trim only with no latch, the BEST 9K Series 1DT is a Grade 1 single dummy trim lever.
8) What does the entrance function do on the 6407LN, and how is it different from a storeroom lock?
Entrance function means the outside lever can be locked and unlocked by key, and the inside lever always retracts the latch for free egress. A storeroom lock keeps the outside lever locked at all times and only the key retracts it. If you want the door to stay secure with no chance of someone leaving it unlocked, look at a storeroom function instead, such as the Hager 2580 with Withnell lever or the Cal-Royal AG05 with deadlocking latchbolt.
9) What finish does the Accentra 6407LN Augusta come in?
626 satin chrome, and that is the only finish offered on the 6407LN. If a building is standardized on 626 across its office and corridor doors, this matches; if you are matching brass or bronze openings, it will not.
10) Is the strike included with the Accentra 6407LN, and can I get a different lip length?
A 1-1/4 inch lip ANSI strike is supplied with the lock. Other lip lengths and strike types are available to order, which matters when the frame is set back from the door face and the standard lip will not reach. All of them are reversible.
11) Does the Augusta 6407LN have a deadlocking latch for a lockable entry door?
Yes. A guardbolt deadlocks the latchbolt when the door is closed, which stops the 1/2 inch latch from being carded or shimmed. That guardbolt is standard on all locking functions in the 6400 Series.
12) What is a Grade 1 lever lock like the Accentra 6407LN worth over a Grade 2 for a multi-tenant building?
Grade 1 is the top ANSI/BHMA commercial tier, tested to higher cycle and strength levels than Grade 2, which is why the 6407LN uses a heavy-gauge steel, zinc-plated and dichromated mechanism. For high-traffic entry doors it holds up longer. On lower-traffic interior openings a Grade 2 entrance lock like the Hager 2525 or the Falcon B511CP6D entry/office lever is the lighter-duty route.
13) What is the difference between the Accentra 6407LN and a residential entry lever like the Kwikset or Master Lock?
The Accentra 6407LN Augusta is a commercial Grade 1 entrance lever with a brass 6-pin cylinder and UL-cUL fire rating up to 1-1/2 hours. The Master Lock BC Series RL01 is a Grade 3 keyed entry lever, and the Kwikset 200BRNL Breton is a Grade 3 passage lever for 1-3/8 to 1-3/4 inch doors. Grade 3 products are built to a residential-level cycle and strength standard, so they sit in a different class from the 6407LN for commercial openings.
14) Is there a keyless option instead of the keyed 6407LN entry lever?
The Accentra 6407LN Augusta uses a brass 6-pin keyed-random cylinder with two keys. If you would rather not issue keys, 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 1150 is a heavy duty mechanical keypad lever set for 1-1/8 inch to 2 inch doors, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. These are code-entry devices rather than cylinder-keyed locks, so they will not join an existing key system.
15) I need access control on the door. What Grade 1 cylindrical lever takes power instead of the 6407LN?
The Accentra 6407LN Augusta is a mechanical entrance lever with no electrical provision. For an electrified opening, the Corbin Russwin CL33903 is a Grade 1 fail safe cylindrical lever lock running on 12VAC/DC for 1-3/4 inch to 2 inch doors, available with an NZ lever and D rose. Fail safe means the lever unlocks on loss of power, so confirm that matches your egress and security plan.
16) The 6407LN must be handed. Is there a non-handed lever I can stock instead?
Handing must be specified for the Accentra 6407LN Augusta. If you would rather carry one part that works either way, the Falcon B101 is a Grade 2 cylindrical passage lever with a non-handed design and the Falcon K101 is a Grade 1 passage lock with non-handed levers. Both are passage function rather than keyed entrance, so they suit corridor and closet doors rather than a locking entry.
17) Will a knob lockset substitute for the Accentra 6407LN?
Not if accessibility matters. The Accentra 6407LN Augusta is a lever-handle lock and is ADA compliant. Knob-style cylindrical locks such as the Arrow HK11 turn-pushbutton entrance lock with ball knob or the Arrow MK33 asylum lock with ball knob use a knob rather than a lever, and knobs do not meet the same accessibility requirement levers do. They are also different functions from the 6407LN entrance function.
18) Can I use the Accentra 6407LN on x-ray room doors in a hospital?
Lead shielding is available to order on the 6400 Series, which is what an imaging or radiology opening needs. Order it as an option; the standard 6407LN does not include it.
19) Does the Accentra 6407LN come preassembled or do I build it up on site?
It arrives preassembled as a cylindrical lockset, so installation is door prep, template, mount and adjust rather than assembling the chassis. Prep has to be cut for the 2-3/4 inch backset and a 1-3/4 inch door leaf.
20) The 6407LN comes in 626 satin chrome only. What if I need a different finish on an entry lever?
The Accentra 6407LN Augusta Monroe lever is offered in 626 satin chrome. If the opening calls for another look, the Bravura Miramar passage leverset is offered in US4 satin brass at Grade 2, and the Deltana Manchester, Morant and Linstead entry levers cover 1-3/8 inch to 2 inch doors in decorative styling. Those are different grade and function classes than the Grade 1 entrance 6407LN, so verify the opening requirement before switching.
