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

1) Will the Accentra 6406LN Monroe lever lock fit a 1-3/8 inch door?
No. The 6406LN is built for 1-3/4 inch doors only, with no adjustment range. On 1-3/8 inch doors you need a lockset that states a range covering it, such as the Dexter C1000 Series (1-3/8 to 1-3/4 inch) or the Falcon K101 (1-3/8 to 2-1/4 inch).
2) What does the service station function do on the 6406LN lever lock?
Service station is a keyed single-cylinder function on the 6406LN Monroe. It is the arrangement used at counters, nurse stations, and service windows where staff control access from one side with a key. The guardbolt deadlocks the latchbolt whenever the door is closed, which is standard on all locking functions in the line. Two keys come with the brass 6-pin keyed-random cylinder.
3) Do I have to specify handing when ordering the Accentra 6406LN?
Yes. Handing must be specified for every function and design in the 6400 Series, so the 6406LN is not field reversible out of the box. The ANSI strike supplied with it is reversible, but the lock itself is not, so confirm the door swing before you order.
4) Will the 6406LN latch into the strike already in my frame?
It depends on your existing prep. The 6406LN uses a 2-3/4 inch backset with a 1/2 inch stainless steel latchbolt throw, and it ships with a 1-1/4 inch lip ANSI strike. If your frame is prepped for an ANSI strike and your bore is on the 2-3/4 inch backset, it drops in. Other lip lengths and strike types can be ordered if your frame or jamb return needs them. Doors bored at 2-3/8 inch backset will not work.
5) Which Grade 1 cylindrical lever lock should I use on a door that does not need a key at all?
The Accentra 6406LN Monroe is a keyed cylindrical lever with a brass 6-pin cylinder, so it is not the part for a non-keyed opening. For a Grade 1 non-keyed passage lever, the Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers and a fire rating, the Falcon T101 is a Grade 1 heavy duty passage lever, and the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage/closet lever. The Dexter C1000 passage is a Grade 1 clutching non-keyed lever as well.
6) What is a Grade 1 alternative to the Accentra 6406LN Monroe lever lock if the opening needs a storeroom function instead of service station?
The Accentra 6406LN Monroe is a service station function Grade 1 cylindrical lever lock. For a keyed storeroom opening where the lever is always locked outside and entry is by key only, the Cal-Royal AG05 is a storeroom lever lockset with a deadlocking latchbolt, and the Hager 2580 with Withnell lever is also a storeroom cylindrical lock. Both are Grade 2 rather than Grade 1, so on a high-traffic commercial door the 6406LN holds the higher ANSI/BHMA grade.
7) The Accentra 6406LN only fits 1-3/4 inch doors. What Grade 1 lever lock covers a thicker or thinner door?
The 6406LN Monroe is built for 1-3/4 inch door thickness only. Where the leaf falls outside that, the Falcon K101 Grade 1 passage lever covers 1-3/8 inch to 2-1/4 inch, the Corbin Russwin CL3110 Grade 1 passage lever covers 1-3/4 inch to 2 inch, and the Dexter C1000 asylum function Grade 1 lock covers 1-3/8 inch to 2 inch. Note that these are different lock functions than service station, so confirm the function matches the opening before substituting on thickness alone.
8) What Grade 1 lever lock should I specify for a classroom or institutional door instead of the Accentra 6406LN service station function?
Service station function on the 6406LN Monroe is not a classroom function. For Grade 1 keyed classroom control, the Dexter C1000 classroom lever is a Grade 1 clutching keyed lock for 1-3/8 inch to 1-3/4 inch doors, and the Dexter C1000 classroom security lever adds keyed control from both sides within the same thickness range. For an institutional or utility door, the Dexter C1000 asylum function is Grade 1 and covers 1-3/8 inch to 2 inch.
9) If the door needs electric access control, what replaces the Accentra 6406LN lever lock?
The 6406LN Monroe is a mechanical keyed cylindrical lever with no electrical provision. For an access-controlled opening, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever lock at 12VAC/DC for 1-3/4 inch to 2 inch doors, available with the NZ lever and D rose. Fail safe means the lever unlocks on loss of power, so confirm that behavior suits the egress and security requirements at that door before swapping from a mechanical lock.
10) Do any alternatives to the Accentra 6406LN come in a Schlage C keyway for an existing master key system?
The Accentra 6406LN Monroe ships with a brass 6-pin keyed-random cylinder and two keys, with a 7-pin cylinder available to order. If the building is keyed to Schlage C, the Cal-Royal AG03 classroom lever is offered with a 6-pin Schlage C keyway keyed different at a 2-3/4 inch backset, the Cal-Royal AG00 entrance lever with a 6-pin Schlage C keyway at a 2-3/8 inch backset, and the Arrow MK33 asylum cylindrical lock with a conventional Schlage C keyway cylinder. Note the AG00 backset differs from the 2-3/4 inch backset on the 6406LN.
11) What finish does the 6406LN Monroe lever come in, and can I match other openings?
626 satin chrome is the only finish offered on the 6406LN. If your building standard is a different finish, this lock will not match and you would need a different series. For a Grade 1 cylindrical lever in other finishes, look at the Corbin Russwin CL3100 Series or the Falcon K101.
12) Can I get the 6406LN with a 7-pin cylinder or keyed into my existing system?
The 6406LN ships with a brass 6-pin keyed-random cylinder and two keys as standard. A 7-pin cylinder is available to order if your facility keying calls for it. Lead shielding is also an option, which matters for x-ray and imaging rooms in healthcare work.
13) Is the Accentra 6406LN heavy enough for a hospital or school corridor?
It is built for that traffic. The mechanism is heavy-gauge steel, zinc plated and dichromated, and the lockset is Grade 1 certified, which is the commercial heavy duty tier used in healthcare, education, and government facilities. The Augusta lever is the trim design.
14) Is there a lower-grade lever lock I can use instead of the Accentra 6406LN on a light-traffic interior door?
The Accentra 6406LN Monroe is a Grade 1 commercial lever lock for heavy-use openings. On interior doors carrying less traffic, Grade 2 cylindrical levers include the Falcon B101 passage lever, the Falcon B511CP6D entry/office lever, the Hager 2510 passage lever with Withnell design, the Hager 2525 commercial entry lever, and the Design Hardware J75 passage lever. Grade 3 options include the Cal-Royal AUS00 entrance/office lever with a solid brass forged body and the Callan Artino entrance leverset. None of these carry a service station function, so match the function to the door.
15) I need a lever that matches the Accentra 6406LN on a door with no latch. What is the dummy equivalent?
The 6406LN Monroe is a functioning cylindrical latch lock with a 1/2 inch stainless steel latchbolt throw, so it is not used on an inactive leaf. For pull-only trim, the BEST 9K Series 1DT is a Grade 1 non-keyed heavy duty single dummy trim cylindrical lever, and the BEST 7KC Series 1DT is a Grade 2 medium duty single dummy lever. The Callan Bentley is a Grade 2 dummy lever, and Emtek offers dummy leversets in pairs for double-door applications.
16) Can I use a keypad or keyless lever lock instead of the Accentra 6406LN to avoid issuing keys?
The 6406LN Monroe is keyed with a brass 6-pin keyed-random cylinder and two keys furnished. If the goal is code entry rather than keys, the Lockey 2835 is a mechanical pushbutton keyless lever lock with ADA compliance fitting 1 3/16 inch to 2 inch doors, the Lockey 1150 is a heavy duty mechanical keypad lever set fitting 1-1/8 inch to 2 inch doors, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. These are passage-function keypad sets rather than a keyed service station lock, so the credential method and the lock function both change.
17) Is the Corbin Russwin 585F715 lever a substitute for the Accentra 6406LN?
No. The Accentra 6406LN Monroe is a complete preassembled cylindrical lever lock with latch, cylinder, and ANSI strike. The Corbin Russwin 585F715 is a Grade 1 lock lever for ED8000 pushpad exit device and CL3300 cylindrical lock series - it is replacement lever trim, not a full lockset, and it is used with an existing device or chassis. If the chassis in the door is failing, the 6406LN replaces the whole lock; if only the lever is damaged on a Corbin Russwin device, the 585F715 is the trim part.
18) Is a Kwikset or Baldwin lever an acceptable replacement for the Accentra 6406LN on a commercial corridor door?
They serve a different duty class. The Accentra 6406LN Monroe is a Grade 1 commercial cylindrical lever with a heavy-gauge steel mechanism and UL-cUL fire rating up to 1-1/2 hours. The Kwikset 200BRNL Breton passage lever and 300BRNL Breton privacy lever are Grade 3 sets for 1-3/8 inch to 1-3/4 inch doors, and the Baldwin Estate 5103 is offered in passage, privacy, and half dummy configurations as decorative residential trim. Those suit residential and light interior use; a fire-rated commercial corridor opening calls for the Grade 1 lock.
19) What should I use instead of the Accentra 6406LN on a bathroom or bedroom door that needs a privacy lock?
Service station function on the 6406LN Monroe uses a keyed cylinder and is not a privacy set. For a push-button privacy lever or knob, the Hager 2540 is a Grade 2 privacy cylindrical lock with a Withnell lever for 1-3/8 inch to 2 inch doors, the Arrow MK02-TA is a privacy cylindrical lock with a Tudor knob that is non-keyed and fire rated, and the Baldwin Estate 5103 privacy lever with 5048 rose covers decorative interior openings.
20) The Accentra 6406LN requires handing to be specified. Which comparable lever locks are non-handed or reversible?
Handing must be specified for all functions and designs on the 6406LN Monroe. If you would rather stock a single non-handed part, the Falcon K101 Grade 1 passage lock uses non-handed levers, the Falcon B101 Grade 2 passage lever is also non-handed, and the Kwikset 200DL Delta passage lever is reversible with an adjustable 6AL latch and RCS strike. By contrast, the Baldwin Estate 5103 half dummy is sold as distinct left hand and right hand parts, so handing matters there too.
21) Is there a Grade 1 lever lock with the same 1-3/4 inch door fit as the Accentra 6406LN but in a flat lever style?
The Accentra 6406LN Monroe uses the Augusta lever design on 1-3/4 inch doors. For a flat lever profile at the same thickness, the Design Hardware X75 is a Grade 1 passage lever lockset with a flat lever specified for 1-3/4 inch doors, and the Design Hardware J75 is the Grade 2 flat lever passage version at that same thickness. Both are passage function, so they carry no cylinder.
22) Is the 6406LN preassembled or do I build it up on site?
It comes preassembled as a cylindrical lockset, so installation is door prep, mount, and adjust rather than parts assembly. The ANSI strike is in the box. Use the manufacturer template for the bore and latch prep, and set handing correctly since the lock is handed.
23) The Accentra 6406LN comes only in 626 satin chrome. What comparable lever lock is available in a brass or nickel finish?
The 6406LN Monroe Augusta lever is offered in 626 satin chrome. Where the building standard is a warmer or brighter finish, the Bravura Miramar passage leverset with round trim is offered in US4 satin brass at Grade 2, and the Callan Asheville passage leverset is offered in satin nickel at Grade 3. Both are passage function rather than keyed service station, so use them where the opening does not need a cylinder.
