Accentra MO-5439LN-626 – Frequently Asked Questions

1) What does storeroom function mean on the Accentra 5439LN, and when should I use it instead of a classroom or entry lock?
Storeroom function means the outside lever is always locked. Entry from outside is by key only, and the inside lever always retracts the latch for free egress. There is no way to leave the outside lever unlocked, which is why it suits storage rooms, mechanical rooms, IT closets and anywhere staff should never be able to leave the door on passage. If you need the outside lever to be unlocked and relocked by key for a teaching space, a classroom function is the right call instead, and if you want a pushbutton or turn to hold it unlocked, look at an entry/office function such as the Hager 2525 in Grade 2.
2) Will the 5439LN lever lock fit a 2-inch thick door?
Yes. The 5439LN adjusts from 1-3/4 inch through 2-1/4 inch door thickness, so a 2 inch door is inside range. What it will not cover is a 1-3/8 inch door, which is common on older interior openings. For those you need a lock with a lower range, such as the Falcon K101 at 1-3/8 to 2-1/4 inch or the Cal-Royal AG05 storeroom lever at 1-3/8 to 1-3/4 inch.
3) My door is bored on a 2-3/8 inch backset. Can I use the Accentra 5439LN?
Standard on the 5439LN is a 2-3/4 inch backset, and the extension links offered are 3-3/4 inch and 5 inch for wider stiles. Nothing shortens it to 2-3/8 inch, so a door already prepped at 2-3/8 inch will not take it without re-prepping the latch bore. For a 2-3/8 inch opening the Cal-Royal AG00 entrance lever is built on that backset.
4) Will the 5439LN latch into the strike already in my frame?
Standard latchbolt throw is 1/2 inch stainless steel, with a 3/4 inch throw available to order. The strike furnished standard is a 1-1/4 inch curved lip sized for a 1-3/4 inch door, and other lip lengths can be ordered. If your frame has an existing ANSI strike prep and the lip reach matches your jamb-to-door-face condition, the existing strike will normally take it, but a deeper frame return is where you order the longer lip.
5) Is the Accentra 5439LN approved for a fire-rated door assembly?
Yes. The 5439LN is UL/cUL fire rated up to 3 hours and carries ANSI/BHMA A156.2 Series 4000 Grade 1. The guardbolt deadlocks the latchbolt when the door closes, which is standard on all locking functions in the series. It is also windstorm certified, subject to your local code review.
6) What cylinder and keying comes with the Accentra 5439LN storeroom lever?
Standard is a brass 6-pin keyed-random cylinder with two keys furnished, single cylinder on the outside. A 7-pin cylinder is available to order if you are tying into a masterkey system that needs it. Keyed-random means each lock ships on its own random key, so if you want keyed alike or master keyed to an existing system, that has to be specified on the order rather than assumed.
7) What is the difference between the Accentra 5439LN and a Grade 2 storeroom lever like the Hager 2580 or Cal-Royal AG05?
Grade level and the door range. The 5439LN is ANSI/BHMA A156.2 Series 4000 Grade 1 with a heavy-gauge steel, zinc-plated and dichromated mechanism, and it covers 1-3/4 to 2-1/4 inch doors. The Hager 2580 storeroom lever with Withnell trim is Grade 2 covering 1-3/8 to 2 inch, and the Cal-Royal AG05 storeroom lever is Grade 2 at 1-3/8 to 1-3/4 inch. For a high-traffic institutional storeroom or a fire-rated opening, the Grade 1 device is the specification; for a lighter-duty door, or a 1-3/8 inch door, the Grade 2 options fit where the 5439LN does not.
8) What is a Grade 2 storeroom lever alternative to the Accentra 5439LN for lighter-traffic openings?
The Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt, and the Hager 2580 with Withnell lever is a Grade 2 storeroom cylindrical lock with a 1-3/8 inch to 2 inch door thickness range. Both keep the storeroom function - key retracts the latch, lever always locked outside - while the Accentra 5439LN is a Grade 1 storeroom lock with Monroe lever that adjusts for 1-3/4 inch to 2-1/4 inch doors. If your doors run thinner than 1-3/4 inch, the Cal-Royal or Hager range covers what the 5439LN does not.
9) I need a non-keyed lever on the same Grade 1 doors as my storeroom locks - what matches?
For openings that need free passage rather than key control, the Falcon K101 is a Grade 1 passage cylindrical lock with non-handed levers, fire rated, and fits 1-3/8 inch to 2-1/4 inch doors - the same upper thickness limit the Accentra 5439LN covers. The Corbin Russwin CL3110 is a Grade 1 vandal resistant passage lever, fire rated, for 1-3/4 inch to 2 inch doors, and the Dexter C1000 passage is Grade 1 with clutching levers. All three hold Grade 1 like the 5439LN but carry no cylinder, so they suit corridor and closet doors where the storeroom function is not wanted.
10) Can I use a Kwikset or Baldwin lever in place of the Accentra 5439LN on a commercial storeroom?
No. The Accentra 5439LN is a commercial Grade 1 storeroom cylindrical lock. The Kwikset 200BRNL Breton is a Grade 3 passage lever for 1-3/8 to 1-3/4 inch doors and the Kwikset 300BRNL is Grade 3 privacy; the Baldwin Estate 5103 is offered as passage, privacy and half dummy. None of those are keyed storeroom locks, so they will not hold a key-controlled storage, electrical or mechanical room. For a keyed entrance-style lever at a lower grade, Cal-Royal AG00 is an entrance lever with a 6-pin Schlage C keyway and 2-3/8 inch backset.
11) I need the lever to release on a fire alarm - what replaces the 5439LN?
The Accentra 5439LN is a mechanical key-operated storeroom lock with no electrical option. For access-control release, 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 or in a keyed version. Fail safe means the lever unlocks when power drops, which is the opposite behavior from the always-locked outside lever of the 5439LN.
12) My doors are 2-1/4 inch thick - which lever locks besides the Accentra 5439LN will fit?
The Accentra 5439LN adjusts from 1-3/4 inch to 2-1/4 inch, and among the comparable levers the Falcon K101 Grade 1 passage is the one that reaches the same 2-1/4 inch limit, listed at 1-3/8 inch to 2-1/4 inch. The Corbin Russwin CL3110 and CL33903 stop at 2 inch, as do the Hager 2510, 2525 and 2580 at 1-3/8 inch to 2 inch. On thick doors, confirm the range before substituting.
13) Do I need to order the 5439LN handed left or right?
No handing to specify. The 5439LN is non-handed and the strikes are reversible, so one part number covers both swings. That is useful for a property manager stocking spares, since a single lock and finish covers every storeroom door in the building regardless of hand.
14) What finishes does the Accentra 5439LN Monroe lever come in?
Nine orderable finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613E dark oxidized satin bronze equivalent, 619 satin nickel, 625 bright chrome, 626 satin chrome, plus BSP black suede and WSP white suede powder coat. PVD is standard on 605 and 606, which is the one to pick for exterior-facing or high-handling doors where a plated brass finish would wear. 626 satin chrome is the usual match for existing commercial openings.
15) Can I get a flat front on the 5439LN instead of the beveled one?
Yes. The front furnished standard is 2-1/4 inch x 1-1/8 inch beveled, and flat fronts are available to order, which is what you want when the existing door edge prep was cut for a flat face plate. Lead shielding is also an available option, relevant for radiology and imaging suites.
16) I need the same Monroe lever look on doors that should not lock. What do I order?
Keep the trim family and change the function. The 5439LN is the storeroom function in the Accentra 5400LN cylindrical series, and the series runs other functions on the same LN rose and lever so the openings match visually. If you are willing to mix brands on non-keyed doors, Grade 1 non-keyed cylindrical options include the Corbin Russwin CL3110 passage lock at 1-3/4 to 2 inch, the Falcon K101 passage at 1-3/8 to 2-1/4 inch, and the BEST 9K Series 1DT single dummy trim for pull-only leaves.
17) Should I use a cylindrical lock like the 5439LN or go to a mortise lock for a heavy commercial storeroom door?
A cylindrical lock bores through the door face and installs faster, and at Grade 1 with a 3-hour UL/cUL fire rating the 5439LN meets most commercial storeroom specs on its own. Go to a mortise lock when the drawing calls for one, when the door already has a mortise pocket you do not want to patch, or when you need functions and trim options a bored lockset does not offer. If the door is already prepped with a 2-1/8 inch cross bore on a 2-3/4 inch backset, the cylindrical route is the low-labor choice.
18) My storeroom door has a wide stile and the lever hits the frame. Does Accentra offer a deeper backset?
Yes. Beyond the 2-3/4 inch standard, the 5400LN series offers 3-3/4 inch and 5 inch extension links to order, which moves the lever off the door edge on wide-stile and narrow-light conditions. Specify the extension link at time of order, since it changes the bore layout on the door prep.
19) What should I use on a utility or patient room door where the 5439LN storeroom lock will not work?
Asylum function keys from both sides, which storeroom does not. 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 heavy duty asylum/institution/utility cylindrical lock with a conventional cylinder in the Schlage C keyway, though it uses a ball knob rather than the Monroe lever on the Accentra 5439LN. Where ADA lever operation is required, the Dexter is the lever-trim option of the two.
20) Is there a keyless alternative to the Accentra 5439LN so I stop issuing keys for a storage room?
The Accentra 5439LN uses a brass 6-pin keyed cylinder with two keys furnished. If you want code entry instead, the Lockey 2835 is a mechanical pushbutton keyless lever lock with ADA compliance for 1-3/16 inch to 2 inch doors, the 2835DC adds a double combination, and the Lockey 1150 is a heavy duty mechanical keypad lever set with adjustable backset for 1-1/8 inch to 2 inch doors. The Delaney LP250 is a Grade 2 electronic keypad leverlock. These change the credential from a key to a code, so keying them into an existing masterkey system is not possible the way it is with the 5439LN cylinder.
21) What matches the 5439LN trim on a door that does not need any latch at all?
For a pull-side-only or inactive leaf, use dummy trim rather than a working lockset. The BEST 9K Series 1DT is a Grade 1 heavy duty single dummy trim cylindrical lever, matching the Grade 1 level of the Accentra 5439LN, and the BEST 7KC Series 1DT is the medium duty Grade 2 equivalent. Callan Bentley is a Grade 2 dummy lever. Dummy trim has no latchbolt, so it cannot secure the storage rooms the 5439LN is intended for.
22) My office doors need the lever to lock and unlock with a key from outside, not stay locked - what do I order beside the 5439LN?
Entrance/office function is the one you want there. The Falcon B511CP6D is a Grade 2 medium duty cylindrical lever with entry/office function, Hager 2525 is a Grade 2 commercial entry lever for 1-3/8 inch to 2 inch doors, and Cal-Royal AUS00 is a Grade 3 entrance/office lever with a solid brass forged body for 1-3/8 inch to 1-3/4 inch doors. The Accentra 5439LN keeps its outside lever locked at all times, which is why it suits storage and mechanical rooms rather than offices.
23) Which Grade 1 passage levers pair with the Accentra 5439LN if I am standardizing a whole floor?
To keep one duty level across a floor, the Grade 1 non-keyed options are the Falcon T101, a heavy duty cylindrical passage lever with pressure release technology, the Falcon K101 Grade 1 passage for 1-3/8 inch to 2-1/4 inch doors, and the Design Hardware X75 Grade 1 passage lever lockset with flat lever for 1-3/4 inch doors. Each carries Grade 1 like the Accentra 5439LN, so the corridor and closet doors run the same duty rating as the keyed storerooms; trim styling will differ from the Monroe lever.
24) Will a Bravura or Callan lever work as a substitute for the Accentra 5439LN?
Those are not interchangeable with a Grade 1 keyed storeroom lock. Bravura Miramar, Atlanta, Orlando and Tampa leversets are all Grade 2 passage function, and Callan Asheville is Grade 3 passage while Callan Artino and Bennett are Grade 3 entrance. The Accentra 5439LN is a Grade 1 storeroom lever with a keyed cylinder, so none of those will provide key-controlled access on a storage, electrical or IT room.
25) Is the Corbin Russwin 585F715 lever a replacement for the Accentra 5439LN?
No. The Corbin Russwin 585F715 is a Grade 1 lock lever for the ED8000 pushpad exit device and the CL3300 cylindrical lock series, covering 1-3/4 inch to 2 inch doors - it is replacement lever trim, not a complete lockset. The Accentra 5439LN is a full cylindrical storeroom lockset with chassis, latch, strike and keyed cylinder. Order the 585F715 only when you are replacing a damaged lever on an existing Corbin Russwin device.
