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

1) Will the Accentra 6405LN storeroom lever fit a 1-3/8 inch door?
No. The 6405LN cylindrical lever lock is built for 1-3/4 inch doors only, with no adjustment range. On older 1-3/8 inch interior doors you need a lock with a thickness range, for example the Cal-Royal AG05 Grade 2 storeroom leverset, which covers 1-3/8 to 1-3/4 inches, or the Hager 2580 storeroom lever at 1-3/8 to 2 inches.
2) How does a storeroom function lever actually work day to day?
Storeroom function means the outside lever is always locked. Entry from the outside is by key only, the inside lever always retracts the latch for free egress, and there is no way to leave the outside lever unlocked. That is what makes the 6405LN right for stock rooms, IT closets, mechanical rooms and utility spaces where the door must never be left open. If you want staff to be able to unlock the outside lever and leave it free, you want an entry/office function instead, such as the Hager 2525 or the Falcon B511CP6D.
3) Do I have to specify handing on the Accentra 6405LN?
Yes, handing has to be given on the order. Accentra requires handing to be specified for all functions and designs in this lock, so it is not a field-reversible lever. The ANSI strike supplied is reversible, but the lock itself is not, so get the door hand right before ordering.
4) Will the 6405LN latch into the strike already in my frame?
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 is already prepped for an ANSI strike (4-7/8 inch), the supplied strike drops in. If your existing strike has a different lip length to clear the frame or trim, other lip lengths and strike types are available to order, and all of them are reversible.
5) Is the 6405LN a 2-3/8 or 2-3/4 inch backset lock?
2-3/4 inch backset. That is the standard commercial bore centerline, so it matches most existing commercial door preps. If the doors in your building were bored at 2-3/8 inches, this lock will not line up.
6) Can I use this lever lock on a fire rated stairwell or storage room door?
The 6405LN carries a UL-cUL fire rating up to 1-1/2 hours, so it can go on a labeled opening within that rating. The guardbolt deadlocks the latchbolt whenever the door is closed, which is standard on all locking functions in this line and is what keeps the latch from being shimmed.
7) What keying comes with the Accentra 6405LN, and can I get it keyed into my building system?
As supplied it is a brass 6-pin keyed-random cylinder with two keys, single cylinder function. Keyed random means each lock has its own unrelated key, so out of the box it will not work in an existing master key system. A 7-pin cylinder is available to order if your facility standardizes on 7-pin.
8) What is a Grade 2 storeroom lever alternative to the Accentra 6405LN for lighter-traffic doors?
The Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever. Both hold the same storeroom function as the Accentra 6405LN, where the key retracts the latch and the outside lever stays locked at all times. The difference is the certification level and the door range: the 6405LN is ANSI/BHMA Grade 1 for 1-3/4 inch doors only, while the AG05 covers 1-3/8 to 1-3/4 inch and the Hager 2580 covers 1-3/8 to 2 inch, so either of those will fit a thinner or thicker door leaf that the 6405LN will not.
9) My door is thicker than 1-3/4 inches. What Grade 1 cylindrical lever can I use instead of the Accentra 6405LN?
The Accentra 6405LN is built for 1-3/4 inch doors only, so a thicker leaf needs a different lock. Among Grade 1 cylindrical levers, the Corbin Russwin CL3110 covers 1-3/4 to 2 inch doors, the Falcon K101 covers 1-3/8 to 2-1/4 inch, and the Dexter C1000 asylum function covers 1-3/8 to 2 inch. Note that the CL3110 and K101 are passage function and the C1000 asylum is a keyed-both-sides institutional function, so none of them reproduce the 6405LN storeroom operation on their own.
10) Is a classroom or entrance lever the same thing as the Accentra 6405LN storeroom lock?
No. The Accentra 6405LN is a storeroom function, meaning the outside lever is always locked and the key alone retracts the latch, with no way to leave the outside lever unlocked. The Cal-Royal AG03 is a classroom lever and the Dexter C1000 classroom is a Grade 1 classroom function, both of which let a key unlock and relock the outside lever for periods of free access. Entrance and office types like the Falcon B511CP6D and the Cal-Royal AUS00 add an inside button or turn that leaves the outside lever unlocked. If the requirement is a door that can never be left unsecured, the storeroom function is the one to hold to.
11) I need the storeroom door to unlock on a fire alarm. What is the alternative to the Accentra 6405LN?
The Accentra 6405LN is a mechanical storeroom lock with no electrical option. For an opening that must release on signal, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever for 1-3/4 to 2 inch doors, offered in a 12VAC/DC keyed version and with the NZ lever and D rose. Fail safe means the outside lever unlocks when power is removed, which is the opposite behavior from the always-locked outside lever on the 6405LN.
12) Is this Grade 1, and how does it compare to Grade 2 storeroom levers for a high traffic building?
The 6405LN is ANSI/BHMA Grade 1, the heaviest commercial cylindrical rating, with a heavy-gauge steel mechanism that is zinc plated and dichromated. For lighter duty or budget openings, the Grade 2 storeroom options are the Cal-Royal AG05 and the Hager 2580 Withnell. If you need Grade 1 in a non-locking companion opening on the same doors, the Corbin Russwin CL3110 passage lever and Design Hardware X75 are Grade 1 passage.
13) What finish does the 6405LN come in, and will it match my other satin chrome hardware?
626 satin chrome is the only finish offered on the 6405LN. That is the standard commercial brushed chrome tone, so it lines up with the 626/US26D hardware already on most commercial openings. If your building standard is a brass or bronze tone, you will not get it in this lock.
14) Can I get this lock for an X-ray room or other lead lined door?
Lead shielding is available to order on the 6405LN, which is what a radiology or imaging opening needs so the bored hole does not become a radiation leak path. It is a special order option, not part of the standard preassembled lock.
15) Does the 6405LN come as one assembly or do I have to order the latch, strike and cylinder separately?
It ships preassembled: lock body, Grade 1 cylindrical chassis, 2-3/4 inch backset latch with 1/2 inch stainless throw, 1-1/4 inch lip ANSI strike, and the brass 6-pin cylinder with two keys. Nothing else is required to hang it beyond a correctly prepped 1-3/4 inch door and the manufacturer template.
16) I need a Grade 1 lever on the same doors but without a key. What pairs with the Accentra 6405LN?
For openings on the same run that do not need to lock, the Grade 1 non-keyed options include the Falcon K101 passage lever, the Falcon T101 heavy duty passage lever with pressure release, the Dexter C1000 passage lever with clutching non-keyed trim, the Design Hardware X75 passage lever for 1-3/4 inch doors, and the Corbin Russwin CL3110 passage/closet lever. All are Grade 1 like the Accentra 6405LN, which is keyed single cylinder with a storeroom function, so pairing keeps the certification level consistent across the doors even though the operation differs.
17) What should I use for the inactive leaf or a pull-only door on a job specified with Accentra 6405LN locks?
A dummy trim matches the lever look without any latch. The BEST 9K Series 1DT single dummy trim is a Grade 1 heavy duty non-keyed cylindrical lever trim, and the BEST 7KC Series 1DT is the Grade 2 medium duty equivalent. Neither latches or locks, so they suit inactive leaves and closet pulls only, unlike the Accentra 6405LN, which carries a 1/2 inch stainless steel latchbolt with a guardbolt that deadlocks it when the door closes.
18) Can a keypad or keyless lever replace the Accentra 6405LN on a storage room?
They change how the door is operated. The Lockey 2835 is a mechanical pushbutton keyless lever lock with a passage function for 1-3/16 to 2 inch doors, the Lockey 1150 is a heavy duty mechanical keypad lever for 1-1/8 to 2 inch doors, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. Those run on a code rather than a cylinder. The Accentra 6405LN uses a brass 6-pin keyed-random cylinder with two keys furnished, which is what keeps the room on an existing key system.
19) Will a residential Grade 3 lever hold up where the Accentra 6405LN is specified?
They are built to different duty levels. The Kwikset 200BRNL Breton passage and the Master Lock RL Series keyed entry lever are Grade 3, and the Callan Artino and Bennett entrance leversets are Grade 3 as well. The Accentra 6405LN is ANSI/BHMA Grade 1 with a heavy-gauge steel mechanism and a UL-cUL fire rating up to 1-1/2 hours, which is what commercial corridor, school, and healthcare specifications typically call for. Grade 3 levers suit interior residential doors rather than a rated commercial storage opening.
20) What is the difference between the Accentra 6405LN and an asylum or institutional function lever?
The Accentra 6405LN is keyed on one side only, single cylinder, with the inside lever always free for egress. The Dexter C1000 asylum (F87) is Grade 1 for 1-3/8 to 2 inch doors and the Arrow MK33-BD-CS is a heavy duty asylum, institution and utility function with a conventional Schlage C keyway cylinder and a ball knob. Asylum function is keyed on both sides, so the inside will not release without a key. That matters for egress code on occupied rooms, where the storeroom function of the 6405LN is usually the compliant choice.
21) Are there lever styles other than the Accentra 6405LN Pacific Beach design for a commercial storeroom?
The Accentra 6405LN carries the Pacific Beach lever in a 626 satin chrome finish. If the aesthetic needs to change on a storeroom door, the Hager 2580 storeroom lock uses the Withnell lever and the Cal-Royal AG05 is a storeroom lever lockset, both Grade 2. The Design Hardware X75 and J75 use a flat lever profile on 1-3/4 inch doors, though those are passage function rather than keyed storeroom.
