Accentra MO-5418LN-626 – Frequently Asked Questions

1) Will the Accentra 5418LN fit a 2 inch thick door?
Yes. The 5418LN adjusts from 1-3/4 inches up to 2-1/4 inches, so a 2 inch door is inside range. What it will not do is a 1-3/8 inch door, which rules it out on older interior openings. For thinner doors, the Falcon K101 covers 1-3/8 to 2-1/4 inches and the Dexter C1000 line runs 1-3/8 to 1-3/4 inches, though neither of those K101 or passage models is a classroom security function.
2) Does the 5418LN work with a 2-3/4 inch backset door prep?
That's the standard prep for it. The 5418LN ships 2-3/4 inch backset, which is the usual commercial bore location. If you're hanging it on a wide-stile or unusual door, 3-3/4 inch and 5 inch extension links are available to order, but you have to call that out on the order.
3) Will the Accentra 5418LN latch into the strike already in my frame?
The standard latchbolt throws 1/2 inch in stainless steel, and the lock ships with a 1-1/4 inch curved lip strike cut for a 1-3/4 inch door. If your existing frame prep uses a different lip length, other lip lengths can be ordered, and all the strikes are reversible so they suit either hand. Where you have a wider gap or need deeper engagement, a 3/4 inch throw is available to order.
4) Is the Accentra 5418LN approved for a fire-rated classroom door?
It carries UL/cUL fire rating up to 3 hours and is certified to ANSI/BHMA A156.2, Series 4000, Grade 1. It is also windstorm certified, which matters in Gulf and coastal jurisdictions where classrooms double as shelter areas, though you should verify against local code for your project.
5) What cylinder and keys come with the Accentra 5418LN, and can I put it on my building master key system?
Standard is a brass 6-pin keyed-random cylinder with two keys furnished. Since this is a classroom security function, it takes a cylinder on each side. A 7-pin cylinder is available to order, and other cylinder and keying arrangements can be specified if you're bringing it onto an existing system rather than using the random keying it ships with.
6) Is a Grade 2 classroom lever like the Cal-Royal AG03 an acceptable substitute for the Accentra 5418LN?
Not on a like-for-like basis. The Cal-Royal AG03 is a Grade 2 classroom lever on a 2-3/4 inch backset, so the backset matches, but Grade 2 is a lighter cycle and strength class than the 5418LN's Grade 1, and the AG03 is a standard classroom function rather than classroom security, so it is keyed outside only. On a high-traffic school corridor that has to lock down from inside the room, the Grade 1 double-keyed 5418LN is the right spec. The Grade 2 is a reasonable choice for a lower-traffic office or storage door.
7) What is the difference between a classroom security lock like the Accentra 5418LN and a standard classroom lock?
A standard classroom function, such as the Dexter C1000 Series classroom lever, is keyed on the outside only, so the outside lever is locked and unlocked from the corridor side. Classroom security, the function of the Accentra 5418LN Monroe, adds a second cylinder on the inside so a teacher can lock the outside lever from within the room without stepping into the corridor. The 5418LN is catalogued as a double cylinder keyed function for that reason. Both the Dexter classroom model and the 5418LN are Grade 1 cylindrical levers.
8) What is the closest equivalent to the Accentra 5418LN Monroe classroom security lever from another manufacturer?
The Dexter C1000 Series classroom security lever lock is the closest match in function and grade. Both are Grade 1 cylindrical lever locks with a classroom security function, meaning both cylinders lock and unlock the outside lever. The Dexter C1000 classroom security model lists a door thickness range of 1-3/8 inch to 1-3/4 inch, while the Accentra 5418LN adjusts from 1-3/4 inch to 2-1/4 inch, so on thicker doors the 5418LN is the one that covers the opening, and on 1-3/8 inch doors the Dexter is the one that fits.
9) Do I need to specify handing when ordering the 5418LN Monroe lever?
No. The 5418LN is non-handed and fully reversible, and the strike is reversible too, so one part number covers left and right hand openings. That's useful when you're stocking spares for a school or a multi-building portfolio and don't want two SKUs on the shelf.
10) What is a guardbolt and does the 5418LN have one?
The guardbolt is the small plunger next to the latch. When the door closes it deadlocks the latchbolt so the latch can't be carded or shimmed back from the corridor side. It's standard on the 5418LN and on all the locking functions in the 5400 Series.
11) What finishes does the Accentra 5418LN Monroe lever come in, and which ones hold up best?
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 and white suede powder coat. The 605 and 606 are PVD as standard, and PVD is also offered on 613, so those are the ones to pick where you want a lifetime finish that won't tarnish in a high-traffic corridor. 626 satin chrome is the usual default for schools matching existing commercial hardware.
12) What front does the 5418LN latch use, and will it drop into an existing beveled prep?
Standard front is a 2-1/4 by 1-1/8 inch beveled face, which is the common commercial latch prep. If your doors are routed for a flat front, that's available to order instead. Lead shielding can also be specified if you're working on x-ray rooms in a healthcare building.
13) I'm standardizing lever hardware across a school. What else in the 5400 Series or from other brands pairs with the 5418LN?
The 5418LN handles the classroom doors. For the non-locking openings in the same building, Grade 1 passage levers that match its duty level include the Corbin Russwin CL3110 (1-3/4 to 2 inch doors, fire rated), the Falcon K101 (1-3/8 to 2-1/4 inch, fire rated) and the Falcon T101. For dummy trim on inactive leaves, the BEST 9K Series 1DT is the Grade 1 option. Keep the finish consistent across all of them, 626 satin chrome being the usual school standard.
14) If the classroom door does not need to lock at all, what lever can be used instead of the Accentra 5418LN?
For a non-locking opening, a Grade 1 passage lever keeps the same heavy duty class without the cylinders. The Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers, fire rated, and covers doors from 1-3/8 inch to 2-1/4 inch. The Corbin Russwin CL3110 is another Grade 1 fire rated passage option for 1-3/4 inch to 2 inch doors. The Accentra 5418LN Monroe is the keyed classroom security version, with a brass 6-pin cylinder and two keys furnished standard.
15) What should be used instead of the Accentra 5418LN on a storeroom or utility door in the same school?
A storeroom function keeps the outside lever locked at all times and is the common pairing with classroom hardware. The Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt for doors 1-3/8 inch to 1-3/4 inch, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with a Withnell lever for doors 1-3/8 inch to 2 inch. For a locked-down utility or seclusion room, the Dexter C1000 asylum function is Grade 1 and covers 1-3/8 inch to 2 inch doors. The Accentra 5418LN Monroe remains the classroom security choice for the instructional spaces.
16) Is a keypad or keyless lever an alternative to the Accentra 5418LN for a classroom?
They are different animals. The Lockey 2835 mechanical pushbutton keyless lever and the Lockey 1150 keypad lever set are passage-function keypad locks covering thinner doors, the 2835 from 1-3/16 inch to 2 inch and the 1150 from 1-1/8 inch to 2 inch. The Delaney LP250 is a Grade 2 electronic keypad leverlock. None of those is a classroom security function. The Accentra 5418LN Monroe is a keyed Grade 1 classroom security lever with cylinders on both sides, which is what a lockdown procedure written around key control calls for.
17) How is the Accentra 5418LN chassis built for heavy classroom traffic?
The mechanism is heavy-gauge steel, zinc-plated and dichromated for corrosion resistance, with a stainless steel latchbolt. Combined with A156.2 Series 4000 Grade 1 certification, that is the construction level intended for doors cycled hundreds of times a day, which is what a classroom or a healthcare corridor sees.
18) Would a Baldwin or Emtek lever work as a substitute for the Accentra 5418LN in a school?
Those are decorative residential-style trims rather than commercial classroom hardware. The Baldwin Estate 5103 is offered in passage, privacy, and half dummy functions, and the Emtek Arts and Crafts and Classic leversets in the set are dummy pairs, which have no latch at all. None of them offers a classroom security function. The Accentra 5418LN Monroe is a commercial Grade 1 cylindrical classroom security lever certified to ANSI/BHMA A156.2 Series 4000 with a UL/cUL fire rating up to 3 hours.
19) What matching dummy or inactive lever pairs with a run of Accentra 5418LN classroom security locks?
For the inactive leaf of a pair of doors, the BEST 9K Series 1DT single dummy trim is a Grade 1 heavy duty non-keyed lever, and the BEST 7KC Series 1DT single dummy trim is the Grade 2 medium duty equivalent. Either gives a lever with no latch on a door that does not need to operate. The Accentra 5418LN Monroe covers the active leaf with its Grade 1 classroom security function and Monroe lever design.
20) What is the difference between the Accentra 5418LN and a Grade 2 entry or office lever on the same corridor?
An entry/office function, such as the Falcon B511CP6D Grade 2 medium duty cylindrical lever or the Hager 2525 Grade 2 commercial entry lock for 1-3/8 inch to 2 inch doors, is intended for offices where the occupant sets the lock with a button or turn. The Accentra 5418LN Monroe is a Grade 1 classroom security lever with a double cylinder keyed function and a guardbolt that deadlocks the latchbolt when the door is closed, with its 1/2 inch stainless steel latchbolt throw as standard.
