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

1) Will the Accentra 6407LN entry lever fit a 1-3/8 inch door?
No. The 6407LN is built for 1-3/4 inch doors only, it isn't a range-adjustable chassis. For a 1-3/8 inch opening you'd need a lockset rated across that range, such as the Hager 2525 Grade 2 entry lever (1-3/8 to 2 inch) or the Cal-Royal AG00 entrance lever (1-3/8 to 1-3/4 inch).
2) Does the Accentra 6407LN drop into an existing 2-3/4 inch backset door prep?
Yes. The 6407LN uses a 2-3/4 inch backset, the standard commercial bore location, so it goes into an existing prep cut for that backset without re-drilling. It ships preassembled with a 1-1/4 inch lip ANSI strike; other lip lengths are available to order if your frame needs more reach across the jamb.
3) Do I have to specify handing when I order the 6407LN lever lock?
Yes, and this is the detail that gets orders returned. Handing must be specified on all functions and designs in this series, so the 6407LN is not field-reversible like a lot of non-handed cylindrical levers. Determine your hand at the opening before ordering. The strike itself is reversible.
4) Can I put the 6407LN on a 90 minute fire rated door?
Yes. The 6407LN carries a UL-cUL fire rating up to 1-1/2 hours, which covers a 90 minute labeled opening. The guardbolt deadlocks the latchbolt when the door is closed, which is standard on all locking functions in this line.
5) What is a Grade 1 alternative to the Accentra 6407LN entrance lever when the door is thicker than 1-3/4 inches?
The Accentra 6407LN Monroe entry lever is built for 1-3/4 inch doors only, so a thicker door needs a different chassis. The Corbin Russwin CL3110 passage lever in the CL3100 Series is Grade 1, fire rated, and covers 1-3/4 inch to 2 inch doors, and the Falcon K101 Grade 1 heavy duty cylindrical lock covers 1-3/8 inch to 2-1/4 inch doors. Both are passage function rather than keyed entrance, so confirm whether the opening actually needs a key. For a keyed Grade 1 option on a 1-3/8 to 2 inch door, the Dexter C1000 Series asylum function lock covers that range.
6) What should I use instead of the Accentra 6407LN if the door needs to stay locked from outside at all times?
The 6407LN Monroe is an entrance function lever, which is unlocked and relocked from the inside. A storeroom function keeps the outside lever locked at all times and requires the key on every entry - the Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever for 1-3/8 inch to 2 inch doors. For a classroom opening, the Dexter C1000 Series classroom lever is Grade 1 and keyed.
7) What is the closest alternative to the Accentra 6407LN if I need the lever to release on a fire alarm or access control signal?
The 6407LN Monroe is a mechanical entrance lever with no electrified option. For an access controlled opening, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever lock running on 12VAC/DC for 1-3/4 inch to 2 inch doors, available with the NZ lever and D rose. Fail safe means the outside lever unlocks when power is removed, so verify that is the behavior your fire and egress plan calls for before specifying it.
8) I need a 2-3/8 inch backset entrance lever, not the 2-3/4 inch of the Accentra 6407LN. What fits?
The 6407LN Monroe is prepped for a 2-3/4 inch backset. For a 2-3/8 inch bore, the Cal-Royal AG00 entrance lever is Grade 2 with a 6-pin Schlage C keyway keyed different and a 2-3/8 inch backset, covering 1-3/8 inch to 1-3/4 inch doors. If you want to stay at 2-3/4 inch but change function, the Cal-Royal AG03 classroom lever in the AG Series uses a 2-3/4 inch backset with the same Schlage C keyway.
9) What does the entrance function do on the Accentra 6407LN, and is it the right choice for an office door?
Entrance function with a single cylinder: the key retracts the latch from outside and the inside lever always allows free egress. It's the usual pick for tenant suite doors, offices and back-of-house entries where staff lock up behind them. If you need a door that stays locked outside at all times with key-only entry, a storeroom function like the Cal-Royal AG05 or Hager 2580 is the better fit; for a classroom where the outside lever is locked and unlocked by key, look at a classroom function such as the Dexter C1000 Classroom.
10) Will the 1/2 inch latchbolt on the 6407LN catch in my existing strike?
The latchbolt is stainless steel with a 1/2 inch throw, which is normal for a cylindrical lockset and will engage a standard ANSI strike pocket. It ships with a 1-1/4 inch lip ANSI strike. On a frame with heavy gap or an offset stop, order a longer lip strike, those are available in other lip lengths and all are reversible.
11) What cylinder and keying comes with the Accentra 6407LN?
A brass 6-pin keyed-random cylinder with two keys is furnished standard. A 7-pin cylinder is available to order if you're tying the lock into an existing 7-pin master key system. Keyed random means each lock arrives on its own key unless you order keying to a system.
12) Is the 6407LN lever ADA compliant for a commercial building?
The Pacific Beach lever design gives ADA compliant operation, meaning it can be operated without tight grasping or wrist twisting. That plus the Grade 1 rating is what makes it usable on office, school, healthcare and government openings where accessible hardware is required.
13) How does the Accentra 6407LN compare to a Grade 2 entry lever like the Hager 2525?
Both are keyed entrance-function cylindrical levers, but they're built for different traffic. The 6407LN is ANSI/BHMA Grade 1 with a heavy-gauge steel, zinc-plated and dichromated mechanism, fixed to 1-3/4 inch doors and a 2-3/4 inch backset. The Hager 2525 is Grade 2 and covers 1-3/8 to 2 inch doors. For a high-cycle corridor or main tenant entry, Grade 1 is the specification; for lighter interior traffic or mixed door thicknesses, the Grade 2 is the practical option. Another Grade 1 cylindrical alternative is the Corbin Russwin CL3100 Series, listed for 1-3/4 to 2 inch doors.
14) Is there a lighter duty entrance lever than the Accentra 6407LN for a lower traffic opening?
The Accentra 6407LN Monroe is an ANSI/BHMA Grade 1 entrance lever. If the opening does not call for 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 lever with entry/office function. Cal-Royal also offers the AUS00 Grade 3 entrance/office lever with a solid brass forged body for 1-3/8 inch to 1-3/4 inch doors. Entrance and entry/office functions differ in how the outside lever is locked and unlocked, so check the function description against how the door is used.
15) Can I use a passage lever in place of the Accentra 6407LN on doors that do not need keys?
Yes, on openings with no locking requirement a passage lever is the correct swap - the 6407LN Monroe is keyed with a single cylinder, which a passage lock does not have. Grade 1 passage options include the Falcon K101 with non-handed levers, the Falcon T101 heavy duty passage lever, the Design Hardware X75 flat lever for 1-3/4 inch doors, and the Corbin Russwin CL3110 passage/closet lever, which is fire rated. Keep the keyed 6407LN on any door that has to lock.
16) Which products look like substitutes for the Accentra 6407LN entry lever but will not actually lock a door?
Several lever products in the same shape are not locks at all. The BEST 9K Series 1DT and BEST 7KC Series 1DT are single dummy trim - a lever on a rose with no latch, used on inactive leaves. The Baldwin Estate 5103 half dummy levers, left and right hand, and the Emtek Arts and Crafts and Cortina dummy pairs are the same idea in a decorative line. None of those latch or accept a key the way the keyed 6407LN Monroe entrance lever does, so they only belong on a door that never needs to secure.
17) Is there a keyless alternative to the Accentra 6407LN for a door where I do not want to issue keys?
The 6407LN Monroe uses a brass 6-pin keyed cylinder with two keys furnished. If you would rather manage codes than keys, the Lockey 2835 mechanical pushbutton keyless lever lock is ADA compliant and fits 1 3/16 inch to 2 inch doors, the Lockey 1150 heavy duty mechanical keypad lever set fits 1-1/8 inch to 2 inch doors, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. Note the Lockey 2835 and 1150 listed here are passage function, so they release rather than secure once the code is entered.
18) For a hospital or detention opening, what replaces the Accentra 6407LN entrance lever?
Entrance function on the 6407LN Monroe allows the inside lever to lock the outside, which is not what most patient or utility rooms want. Asylum function locks or unlocks both levers by key only, with no inside free egress by lever - the Dexter C1000 Series asylum (F87) is Grade 1 and covers 1-3/8 inch to 2 inch doors. Arrow also offers the MK33-BD-CS asylum/institution/utility cylindrical lock in Grade 2 with a ball knob and a conventional cylinder in Schlage C keyway. Confirm local egress code allows a key-only function on the opening.
19) I'm standardizing lever locks across a building. What finish does the 6407LN come in?
626 satin chrome, and that's the only finish offered on the 6407LN. If your existing openings are in 626 you can match straight across; if the building is in oil-rubbed bronze or brass you'll need a different series to match.
20) Can I get the 6407LN with lead shielding for an X-ray room?
Lead shielding is available to order on this series, which is what healthcare facilities need for radiology and imaging suite doors. It is not part of the standard build, so it has to be called out on the order.
21) Does the Accentra 6407LN come preassembled or do I build the chassis on site?
It arrives preassembled as a cylindrical lockset, so installation is door prep, mount, and adjust rather than chassis buildup. Use the manufacturer template to mark the bore and latch holes, confirm you have a 1-3/4 inch door and a 2-3/4 inch backset prep, then set the lock and check that the latch and guardbolt seat cleanly in the strike.
22) The Accentra 6407LN only comes in 626 satin chrome - what comparable levers offer other finishes?
The 6407LN Monroe entry lever is supplied in 626 satin chrome. If the job needs a different finish, the Hager 2580 storeroom lever is offered in 26D, the Cal-Royal AG05 storeroom lockset in 26D, the Bravura Miramar passage leverset in US4 satin brass, and the Callan Asheville passage leverset in satin nickel. Those peers differ in grade and function from the Grade 1 keyed entrance 6407LN, so match the function first and the finish second.
23) Is there an entrance lever comparable to the Accentra 6407LN that comes with a deadbolt?
The 6407LN Monroe is a single cylinder keyed entrance lever with a 1/2 inch stainless steel latchbolt and guardbolt, sold without a deadbolt. If the opening needs a separate deadbolt throw, the Callan Bennett is a Grade 3 entrance leverset supplied as a deadbolt combo. The Callan Artino is another Grade 3 entrance leverset if you only need the lever. Both sit at a lower grade than the Grade 1 6407LN, so weigh that against the traffic on the door.
