Accentra MO-5405LN-626 – Frequently Asked Questions

1) Will the Accentra 5405LN storeroom lever fit a 2-inch thick door?
Yes. The 5405LN is adjustable from 1-3/4 inch up to 2-1/4 inch door thickness, so 2 inch is inside its range with no extension kit. That upper range is wider than most cylindrical levers, which stop at 1-3/4 or 2 inches, so it works on gasketed fire doors and built-up doors where a standard lockset runs out of spindle.
2) Will the 5405LN latch into the strike that is already in my frame?
Standard throw on the 5405LN latchbolt is 1/2 inch stainless steel, which is what a normal ANSI strike pocket is cut for, and it ships with a 1-1/4 inch curved lip strike sized for a 1-3/4 inch door. If your frame has a deeper pocket or you need more engagement on a warped or weatherstripped opening, a 3/4 inch throw is available to order. Other lip lengths are also an order option when the frame sits proud of the door face, and all the strikes are reversible.
3) Do I need to specify handing for the Accentra 5405LN lever lock?
No handing to call out. The 5405LN is non-handed and reversible, and the strike is reversible too, so one part number covers left and right hand openings. For a property manager stocking spares across a building, that means a single lock on the shelf fits any door in the run.
4) What does storeroom function mean on the Accentra 5405LN, and is it the right function for a mechanical room?
Storeroom function means the outside lever is always locked and only the key retracts the latch. The inside lever always retracts free for egress. There is no button or thumbturn to leave the door unsecured, which is exactly why it suits mechanical rooms, electrical closets, IT rooms, and stock rooms. If you want staff to be able to leave the door unlocked during the day, storeroom is the wrong function and an entry/office lock is what you want.
5) Is the Accentra 5405LN fire rated for a 3-hour opening?
Yes. The 5405LN carries UL/cUL fire ratings up to 3 hours, and it is ANSI/BHMA A156.2 Series 4000 Grade 1. It is also windstorm certified, subject to your local code. Those are the two boxes an institutional or MRO spec usually needs checked on a labeled stair or corridor door.
6) Can I order the Accentra 5405LN without a cylinder so I can key it to my own system?
Yes. Every finish on the 5405LN is orderable either less cylinder or with a conventional cylinder in the PARA-E1R keyway. Locksmiths and integrators running an existing masterkey system normally take the less cylinder version and drop in their own. The factory cylinder is brass, 6-pin, keyed random with two keys; 7-pin is an order option.
7) What is the difference between the Accentra 5405LN and a Grade 2 storeroom lever like the Hager 2580 or Cal-Royal AG05?
All three are storeroom function levers, but the 5405LN is ANSI/BHMA Grade 1 while the Hager 2580 with Withnell lever and the Cal-Royal AG05 with deadlocking latchbolt are both Grade 2. Grade 1 is the higher cycle and strength tier, which is what an institutional spec normally calls for on a corridor or mechanical room. The Grade 2 options cover 1-3/8 inch to 2 inch and 1-3/8 inch to 1-3/4 inch doors respectively, so on a thick door above 2 inches the Accentra is the one that fits.
8) What is the closest Grade 1 storeroom lever lock to the Accentra 5405LN if I need a different brand on the same door?
For a Grade 1 cylindrical storeroom opening, the closest peer in storeroom function is the Cal-Royal AG05, a Grade 2 storeroom lever lockset with a deadlocking latchbolt, and the Hager 2580, a Grade 2 storeroom lock with the Withnell lever. Both hold the same storeroom behavior the 5405LN provides - key retracts the latch, outside lever stays locked at all times - but they are certified to ANSI/BHMA Grade 2 rather than the Grade 1 the 5405LN carries. If the specification on the drawing calls for Grade 1 specifically, stay with the 5405LN; if the spec calls only for storeroom function, the AG05 and 2580 meet it. Note also that the AG05 covers 1-3/8 inch to 1-3/4 inch doors and the 2580 covers 1-3/8 inch to 2 inch, while the 5405LN adjusts from 1-3/4 inch to 2-1/4 inch, so thick doors point back to the Accentra.
9) The door does not need to lock - what Grade 1 lever should go on it instead of a storeroom lockset?
A storeroom lockset like the 5405LN keeps the outside lever locked and needs a key on every entry, which is wasted on a corridor or closet door that only needs latching. For those openings the Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers, fire rated, covering 1-3/8 inch to 2-1/4 inch doors; the Falcon T101 is a Grade 1 heavy duty passage lever with pressure release technology; and the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage/closet lever, fire rated, for 1-3/4 inch to 2 inch doors. All three hold Grade 1 like the 5405LN, so the abuse resistance of the specification is preserved while the keying and cylinder cost drops off the door entirely.
10) I need a keyed Grade 1 lever but the room is a classroom, not a storeroom - what changes?
Storeroom function on the 5405LN means the outside lever is permanently locked and the key only retracts the latch; it never leaves the door unlocked. A classroom opening usually needs the key to actually lock and unlock the outside lever from the corridor. The Dexter C1000 Classroom is a Grade 1 clutching keyed cylindrical lever in classroom function for 1-3/8 inch to 1-3/4 inch doors, and the Dexter C1000 Classroom Security is the same Grade 1 clutching keyed platform in classroom security function over the same thickness range, which adds inside keyed control of the outside lever. Both are Grade 1 like the 5405LN, so the difference is purely which door the function belongs on.
11) What is the difference between the Accentra 5405LN and the Dexter C1000 Entry/Office for an office suite door?
The 5405LN is a storeroom lock: the outside lever never unlocks, so staff must key in every time. The Dexter C1000 Entry/Office is a Grade 1 clutching keyed cylindrical lever in entrance/office function for 1-3/8 inch to 1-3/4 inch doors, where the outside lever can be left unlocked for business hours and secured at the end of the day. Both are Grade 1 cylindrical lever locks. Pick the 5405LN where the room must stay secure regardless of who last used it - IT closets, mechanical rooms, stock rooms - and the C1000 Entry/Office where the door needs to be free during the day. Door thickness also splits them: the 5405LN adjusts from 1-3/4 inch to 2-1/4 inch.
12) Which lever locks look like a substitute for the 5405LN storeroom but are not?
Several cylindrical levers sit in the same family without doing the same job. The Falcon B101 and Design Hardware X75 are passage locks with no cylinder and no locking at all. The Arrow MK02-TA is a privacy set operated by a thumbturn from inside, not a key. The BEST 9K 1DT is single dummy trim - a fixed lever with no latch behind it. The Kwikset 200BRNL Breton is a Grade 3 passage lever for residential-weight 1-3/8 inch to 1-3/4 inch doors. None of these secure a stock room, mechanical room, or IT closet the way the keyed storeroom function of the 5405LN does. If the door needs to stay locked against the corridor and open only with a key, the substitute must be storeroom or classroom function, not passage, privacy, or dummy.
13) I need to key the door to an existing Schlage C system - does the Accentra 5405LN work?
The 5405LN ships with a conventional cylinder in the PARA-E1R keyway, and it is also available less cylinder so a locksmith can install a cylinder from the keying system already in the building. If the site standard is Schlage C and supplying the cylinder separately is not wanted, peers that come with a Schlage C keyway cylinder factory-installed include the Cal-Royal AG03 classroom lever, the Cal-Royal AG00 entrance lever with a 6-pin Schlage C keyway keyed different and a 2-3/8 inch backset, and the Arrow MK33-BD-CS asylum lock with a conventional Schlage C cylinder. Note the AG00 uses a 2-3/8 inch backset while the 5405LN is 2-3/4 inch standard, so the door prep is not the same.
14) The opening needs to release on a fire alarm - what replaces a mechanical storeroom lever?
The 5405LN is mechanical: the outside lever is locked until a key turns it, and nothing about that changes when an alarm sounds. For an access controlled opening that must unlock on power loss, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever running on 12VAC/DC with the NZ lever and D rose, for 1-3/4 inch to 2 inch doors, and the CL33903 keyed 12AD version is the same Grade 1 fail safe electrified lever from the CL33900 series over the same thickness range. Both are Grade 1 like the 5405LN, but they require power and wiring to the door, including an electric hinge or door loop, which the 5405LN does not.
15) My doors are 1-3/8 inch thick - which lever lock fits when the 5405LN does not?
The 5405LN adjusts from 1-3/4 inch to 2-1/4 inch, so a 1-3/8 inch leaf falls below its range. Peers that start at 1-3/8 inch include the Falcon K101 Grade 1 fire rated passage lock at 1-3/8 inch to 2-1/4 inch, the Dexter C1000 Asylum Grade 1 at 1-3/8 inch to 2 inch, the Dexter C1000 Entry/Office Grade 1 at 1-3/8 inch to 1-3/4 inch, the Cal-Royal AG05 Grade 2 storeroom at 1-3/8 inch to 1-3/4 inch, and the Hager 2580 Grade 2 storeroom at 1-3/8 inch to 2 inch. If the function must stay storeroom on a thin door, the AG05 and the 2580 are the two that match both the thickness and the function.
16) What finishes is the Accentra 5405LN Monroe lever available in?
Nine finishes are orderable: 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 Black Suede and White Suede powder coat. 605 and 606 come as PVD, which holds up better than lacquered brass on an exterior or high-traffic door. 626 satin chrome is the usual match if the rest of the building is on commercial hardware.
17) Does the 5405LN have a deadlocking latch so the door cannot be carded open?
It does. A guardbolt deadlocks the latchbolt whenever the door is closed, and it is standard on all locking functions in the 5400LN line. That is what stops a credit card or shim attack on the latch, and it is a requirement on most exterior and secured storage openings.
18) I need matching Grade 1 levers on the non-locking doors in the same building. What pairs with the Accentra 5405LN?
For passage and closet doors in the same run, the Falcon K101 is a Grade 1 non-handed passage cylindrical lever rated for 1-3/8 inch to 2-1/4 inch doors and fire rated, which matches the 5405LN's thickness range door for door. The Corbin Russwin CL3110 is another Grade 1 fire rated passage option, covering 1-3/4 inch to 2 inch. For dummy trim on inactive leaves, the BEST 9K Series 1DT is a Grade 1 heavy duty single dummy lever. Lever style will not match across brands, so if visual consistency matters, stay within one series.
19) I need a keyed lever on an access-controlled door that unlocks electrically. Is the 5405LN the right choice?
No. The 5405LN is a mechanical storeroom lock, key-operated only, with no electrification. For an opening tied to a card reader or access control panel, the Corbin Russwin CL33903 is a Grade 1 electrified fail safe cylindrical lever running 12VAC/DC, rated for 1-3/4 inch to 2 inch doors. Use the 5405LN where mechanical key control is all that is needed.
20) What front does the Accentra 5405LN latch come with, and will it drop into an existing routed door edge?
Standard front on the 5405LN latch measures 2-1/4 x 1-1/8 inches and is beveled, which is the common commercial cylindrical latch face, so it usually drops straight into an existing routed edge. Flat fronts are available to order if the door already has a square-cut mortise. Lead shielding is also an order option for X-ray rooms in healthcare work.
21) Can a Grade 2 lever lock replace a Grade 1 storeroom lock on a high traffic door?
It depends on what the specification requires. The 5405LN is certified to ANSI/BHMA A156.2 Series 4000 Grade 1. Grade 2 storeroom alternatives include the Cal-Royal AG05 with a deadlocking latchbolt and the Hager 2580 with the Withnell lever, and Grade 2 entrance-function options include the Hager 2525 commercial cylindrical entry lock for 1-3/8 inch to 2 inch doors and the Falcon B511CP6D medium duty entry/office lever. Those Grade 2 sets carry a lower ANSI cycle and strength classification than the Grade 1 the 5405LN holds, so on institutional corridors, schools, and healthcare doors where the drawing calls out Grade 1, they will not satisfy the submittal. On back-of-house or light commercial doors with no grade callout, they are legitimate substitutes.
22) What should go on a patient room or holding room instead of a storeroom lever lock?
Storeroom function locks the outside lever only; it does not give staff key control from both faces of the door. For behavioral health, holding, and utility rooms where the door must be keyed on both sides, asylum function is the right call: the Dexter C1000 Asylum is a Grade 1 cylindrical lock in asylum/institution/utility function covering 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is a heavy duty asylum lock with a ball knob and a conventional Schlage C keyway cylinder. The Dexter matches the 5405LN at Grade 1. Where the room is simply secured stock or equipment and staff enter from the corridor with a key, the 5405LN storeroom function remains the correct function.
23) Is there a keyless option instead of putting a keyed storeroom lock on a back door?
The 5405LN is a keyed single cylinder lock, so every person entering carries a key. Where the goal is controlled entry without issuing keys, mechanical and electronic keypad levers cover the same door: the Lockey 1150 is a heavy duty mechanical keypad lever set with double combination for 1-1/8 inch to 2 inch doors, the Lockey 1150S adds an adjustable backset over the same thickness range, and the Lockey 2835DC is a double combination keyless lever for 1-3/16 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, and their door thickness ranges stop at 2 inch where the 5405LN adjusts to 2-1/4 inch, so verify the leaf before switching.
24) Can I use dummy trim to match the Monroe lever on inactive doors while keeping the 5405LN on the working leaves?
On an inactive leaf or a closet face that only needs a pull, a dummy lever gives the same visual line without a latch. The BEST 9K 1DT is Grade 1 heavy duty single dummy trim, matching the Grade 1 heavy duty class of the 5405LN, and the BEST 7KC 1DT is the Grade 2 medium duty equivalent. The Callan Bentley is a Grade 2 dummy lever, and Emtek offers dummy pairs in the Arts and Crafts, Hammered, and Cortina levers. Note that these are separate lever designs, not the Monroe trim the 5405LN carries, so the two leaves will read as different families side by side - a dummy lever matches on function, not on appearance.
25) Is a residential grade lever an acceptable substitute for a commercial storeroom lock in an apartment building?
The 5405LN is a commercial Grade 1 lock, and inside a multi-tenant building it is the right choice for corridor, mechanical, and stock room doors that see constant traffic. Grade 3 levers such as the Cal-Royal AUS00 entrance/office lock with a solid brass forged body for 1-3/8 inch to 1-3/4 inch doors, the Callan Artino entrance leverset, the Master Lock RL series keyed entry lever, and the Kwikset 200BRNL Breton passage set are built to the residential classification. Grade 3 carries a lower ANSI cycle and force rating than the Grade 1 the 5405LN holds, so on unit interior doors they suit the application, while shared and back-of-house openings are where the Grade 1 lock belongs.
26) What lever goes on the exit device at the other end of the corridor if the 5405LN is on the stock room?
The 5405LN is a complete cylindrical lockset that mounts in a bored door prep; it does not fit an exit device. Where the corridor door carries a pushpad device, the Corbin Russwin 585F715 is a Grade 1 lock lever for the ED8000 pushpad exit device, drawn from the CL3300 cylindrical lock series and covering 1-3/4 inch to 2 inch doors, and the Imperial USA ED-EL500HD is a heavy duty escutcheon lever trim in entry function from the ED-500 series. Those are outside trim for a rim or mortise exit device, not standalone locks - ordering one expecting a cylindrical lockset leaves the opening without a latch mechanism.
27) What is the Monroe trim on the Accentra 5405LN?
Monroe is the lever style, a return lever design on the 5400 Series cylindrical chassis. It is a trim designation, not a function change, so a 5405LN with Monroe trim performs identically to any other lever design in the series. If you are matching levers already installed elsewhere in the building, Monroe is the name to give the supplier.
28) How is the 5405LN chassis built for a high-traffic door?
The mechanism is heavy-gauge steel, zinc-plated and dichromated for corrosion resistance, and the latchbolt is stainless steel. Combined with the Grade 1 rating under A156.2 Series 4000, that is the construction spec for corridor, stairwell, and stock room doors that see constant cycling.
