Accentra MO-5401LN-626 – Frequently Asked Questions

1) Will the Accentra 5401LN Monroe passage lever fit a 2 inch thick door?
Yes. The 5401LN chassis adjusts from 1-3/4 inch through 2-1/4 inch door thickness, so a 2 inch door is inside the range with no extension kit. Note the bottom of that range: at 1-3/8 inches, a common older interior thickness, this lock is not the right choice. For a thinner door look at the Falcon K101 Grade 1 passage lever, which covers 1-3/8 inch to 2-1/4 inch.
2) Do I have to specify left or right hand for the 5401LN Monroe lever?
No handing to call out. The 5401LN is non-handed and the strike is reversible, so one part number covers both swings. That is the reason it works well as a building standard: a property manager can stock one lock for every passage opening in the fleet regardless of which way the door swings.
3) Can I put this passage lever on a fire rated door?
Yes. The 5401LN is UL/cUL fire rated up to 3 hours, so it can go on labeled openings up to a 3 hour rating. It is also ANSI/BHMA A156.2 Series 4000 Grade 1 and carries the F75 function designation for passage latch.
4) Will the 5401LN latch into the strike already in my frame?
Standard build is a 1/2 inch stainless steel latchbolt throw on a 2-3/4 inch backset, with a 1-1/4 inch curved lip strike sized for a 1-3/4 inch door and a 2-1/4 inch by 1-1/8 inch beveled front. If your existing frame prep uses a deeper pocket or a longer lip, both are order options: 3/4 inch throw, other lip lengths, and flat fronts are all available to order. Backset extension links for 3-3/4 inch or 5 inch are also orderable if the bore is set back for a glass or rail stile door.
5) What is the closest Grade 1 equivalent to the Accentra 5401LN Monroe passage lever?
The Accentra 5401LN Monroe is an ANSI/BHMA Grade 1 non-keyed passage cylindrical leverset. The closest peers on the same grade and function are the Falcon K101, a Grade 1 heavy duty passage cylindrical lock with non-handed levers and a 1-3/8 inch to 2-1/4 inch door thickness range, the Falcon T101 Grade 1 heavy duty passage lever, the Corbin Russwin CL3110 Grade 1 vandal resistant passage/closet lever, and the Dexter C1000 Grade 1 passage lever with clutching. The 5401LN adjusts from 1-3/4 inch to 2-1/4 inch doors, so on a thin 1-3/8 inch door the K101 or the Dexter C1000 passage covers a range the Monroe does not.
6) The 5401LN will not lock. What do I order if the door needs to be keyed or secured?
Correct, the 5401LN Monroe is a non-keyed passage function with no locking at all - the lever is always free on both sides. For a door that has to secure, step to a keyed function: the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever, the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt on 1-3/8 inch to 1-3/4 inch doors, the Dexter C1000 classroom is a Grade 1 keyed classroom lever with clutching, and the Falcon B511CP6D is a Grade 2 entry/office lever. For a bath or bedroom, the Hager 2540 or the Arrow MK02-TA covers privacy.
7) Which passage lever should I use on a thin 1-3/8 inch door if the 5401LN starts at 1-3/4 inch?
The Accentra 5401LN Monroe adjusts from 1-3/4 inch to 2-1/4 inch, so a 1-3/8 inch leaf is below its range. For thin doors, the Falcon K101 Grade 1 passage lock covers 1-3/8 inch to 2-1/4 inch, the Dexter C1000 passage lever covers 1-3/8 inch to 1-3/4 inch at Grade 1, and on the Grade 2 side the Hager 2510 covers 1-3/8 inch to 2 inch. The K101 is the only one of those that spans both the thin door and the full 2-1/4 inch range the Monroe reaches, which matters if you are standardizing one part number across mixed leaf thicknesses.
8) What finishes does the Accentra 5401LN Monroe lever come 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 BSP black suede powder coat and WSP white suede powder coat. PVD is standard on 605 and 606, which matters if the openings see heavy hand traffic or coastal air and you do not want brass to tarnish. 626 satin chrome is the usual match for existing commercial hardware.
9) Should I use a Grade 1 passage lever like the 5401LN or is Grade 2 enough?
Grade 1 is the top ANSI/BHMA commercial tier and is what you want on high-cycle openings: school corridors, hospital wings, back-of-house doors in hotels. The 5401LN meets it with a heavy-gauge steel, zinc-plated and dichromated mechanism. For a light-traffic interior office or a tenant closet, a Grade 2 passage lever such as the Falcon B101 or the Arrow GL01 is a reasonable step down. Do not drop below that on a labeled or public corridor door.
10) Is there a lighter duty passage lever for low traffic doors instead of the 5401LN?
Yes. The 5401LN Monroe is Grade 1 for heavy commercial traffic. For interior hall and closet doors that see light use, the Falcon B101 is a Grade 2 medium duty non-handed passage cylindrical lever, the Hager 2510 is a Grade 2 passage cylindrical lever in the Withnell design covering 1-3/8 inch to 2 inch doors, the Arrow GL01 is a Grade 2 passage lock with the Sierra lever for 1-3/4 inch to 2 inch doors, and the Design Hardware J75 is a Grade 2 passage lever for 1-3/4 inch doors. All are passage function, so the door prep intent is the same; the cycle rating and chassis duty are what differ.
11) Can I use a dummy lever in place of the 5401LN on an inactive leaf?
No - the 5401LN Monroe is a working passage lockset with a latchbolt that retracts when the lever is turned, so it latches the door closed. A dummy has no latch and is surface mounted trim only. For an inactive leaf or a door held by a ball catch, order a dummy instead: the BEST 9K Series 1DT is a Grade 1 heavy duty single dummy trim cylindrical lever, and the BEST 7KC Series 1DT is the Grade 2 medium duty single dummy. The Callan Bentley BN5051 is a Grade 2 dummy lever. Pick the dummy only where nothing needs to latch.
12) I want keyless code entry instead of a 5401LN passage lever. What are the options?
The 5401LN Monroe is a mechanical passage lever with no code or keypad. For keyless entry on a similar cylindrical lever prep, the Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function and ADA compliance for 1 3/16 inch to 2 inch doors, the Lockey 2835DC adds a double combination on the same thickness range, and the Lockey 1150 is a heavy duty mechanical keypad lever set with double combination passage function for 1-1/8 inch to 2 inch doors. The Delaney LP250 is a Grade 2 electronic keypad leverlock if you want electronic rather than mechanical code entry. Note all of these fall short of the 2-1/4 inch maximum door thickness the Monroe reaches.
13) If the opening needs an electrified lever rather than a mechanical passage set, what replaces the 5401LN?
The 5401LN Monroe is purely mechanical with no electrical option. For access control tie-in on a cylindrical prep, 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, offered with the NZ lever and D rose. Fail safe means the lever unlocks on power loss, so confirm that behavior against your fire and egress plan before ordering, and note the 2 inch door ceiling versus the 2-1/4 inch the Monroe reaches.
14) Can a patient-room or institutional lock substitute for the 5401LN on a healthcare door?
Only if the door actually needs a locking function. The 5401LN Monroe is passage-only and is commonly used for corridor and hall doors in healthcare and institutional buildings where free access both ways is required. Where the opening must lock, the Dexter C1000 asylum is a Grade 1 cylindrical lock in the F87 asylum/institution/utility function for 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is a heavy duty asylum function cylindrical lock with a conventional cylinder in the Schlage C keyway. Those are key-both-sides functions, a different egress behavior from the Monroe, so verify them against the code for your facility type.
15) Does the 5401LN passage lever include a guardbolt?
The guardbolt, which deadlocks the latchbolt when the door closes, is standard on the locking functions in the 5400LN line. Passage has nothing to secure, so that feature belongs on the keyed and pushbutton versions rather than here. What you get with the 5401LN is the Monroe lever on a free wheeling mechanism with a 1/2 inch stainless latchbolt.
16) I need a matching lever on a door that does not latch. What do I order?
A passage lockset like the 5401LN always has a working latch, so for a closet face, an inactive leaf or a false door you want dummy trim instead. The BEST 9K Series 1DT single dummy is the Grade 1 heavy duty non-keyed option; the 7KC Series 1DT is the Grade 2 version. Match the finish across both so the openings read the same.
17) Can the 5401LN be ordered with lead shielding for an X-ray room?
Yes, lead shielding is an order option on the 5400LN cylindrical line, which is what you need for imaging suites and radiology door openings in a healthcare facility. Call it out on the order along with your finish and backset, because it is not part of the standard build.
18) We need a decorative passage lever on a residential-style opening, not the commercial Monroe. What else works?
The Accentra 5401LN Monroe is a commercial cylindrical leverset. Where the look drives the choice, the Baldwin Estate 5103 passage lever with the 5048 rose is a decorative passage option, and Bravura offers several Grade 2 passage leversets with round or square trim: the Miramar BV940-106 in US4 satin brass, the Atlanta and Orlando with round trim, and the Tampa with square trim. These are styled for finished residential and hospitality interiors rather than the heavy-traffic commercial openings the Grade 1 Monroe is built for.
