Accentra YAL-MO-5318LN-626 – Frequently Asked Questions

1) Will the Accentra 5318LN Monroe lever lock fit a 1-3/4 inch classroom door?
Yes. The 5318LN is adjustable from 1-3/4 inch to 2 inch door thickness out of the box, which covers the standard commercial 1-3/4 inch door and thicker leaves. If your doors are thinner or thicker than that band, the lock can be ordered prepped for other thicknesses instead of adjusted in the field. Backset is 2-3/4 inch standard, and 2-3/8, 3-3/4 or 5 inch extension links can be ordered when the existing bore does not sit at 2-3/4.
2) What does classroom security function mean on the Accentra 5318LN, and how is it different from a standard classroom lock?
Classroom security is a double cylinder function: there is a keyed cylinder on both the outside and the inside. A teacher can lock the outside lever from inside the room with a key without opening the door and stepping into the corridor. A standard classroom lock is keyed on the outside only, so locking down means going into the hallway. That inside-key lockdown is the whole reason schools specify the 5318LN over a plain classroom lock.
3) Do I have to order the Accentra 5318LN handed for a left or right hand door?
No handing to specify. The 5318LN Monroe lever is non-handed and the front is universal for both flat and beveled door edges, so one part covers either swing and either edge prep. The strikes are reversible as well. For a property manager keeping stock on a shelf, that means a single part number covers every classroom door in the building.
4) Will the Accentra 5318LN 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 curved lip strike sized for a 1-3/4 inch door. If your existing frame has a different lip length, other lip lengths can be ordered, and every strike is reversible. A guardbolt is standard on the locking functions, deadlocking the latchbolt once the door is closed so it cannot be shimmed or carded.
5) What cylinder and keying comes with the Accentra 5318LN, and can I get 7-pin?
Each 5318LN carries brass 6-pin cylinders, keyed random, with two keys furnished. Because it is a double cylinder function there is a keyed cylinder inside as well as outside. 7-pin is not offered on this lock, so if your facility standard is a 7-pin small format or large format system, this is not the lock to specify.
6) My classroom doors are 1-3/8 inch. Can I still use the Accentra 5318LN?
Not as adjusted from the carton. The 5318LN covers 1-3/4 to 2 inch, and other thicknesses have to be ordered prepped rather than dialed in on site. For an existing 1-3/8 inch leaf, the Dexter C1000 Series classroom security lever is built for 1-3/8 to 1-3/4 inch and gives you the same inside-key lockdown. Falcon's K101 covers 1-3/8 to 2-1/4 inch but it is a passage function, so it will not lock at all.
7) Difference between classroom security and standard classroom function when choosing a lever lock?
Classroom security means the door can be locked and unlocked by key from either side, which is why the Accentra 5318LN Monroe is a double cylinder lock - a teacher can secure the door from inside without stepping into the corridor. A standard classroom function such as the Cal-Royal AG03 Classroom Lever, a Grade 2 lever with a 6-pin Schlage C keyway keyed different and a 2-3/4 inch backset, is keyed from the outside only. The Dexter C1000 Classroom (DEX-C1000-CLRM), a Grade 1 clutching keyed lever, is the Grade 1 version of that outside-key-only arrangement. If the district specification calls for lockdown from inside the room, only the classroom security function satisfies it.
8) Can a Grade 3 residential lever be used where a classroom security lock is specified?
No. Grade 3 levers such as the Kwikset 200BRNL RDT Breton passage set for 1-3/8 inch to 1-3/4 inch doors, the Callan Artino entrance leverset, or the Master Lock BC Series return style keyed entry lockset are built for residential entrance and interior duty. The Accentra 5318LN Monroe is a commercial ANSI/BHMA A156.2 Series 4000 Grade 2 lock, UL/cUL fire rated up to 3 hours, with a heavy-gauge steel zinc-plated mechanism and a guardbolt that deadlocks the latchbolt when the door closes. An institutional opening carrying a fire rating and a lockdown requirement needs the commercial-grade lock.
9) Which lock goes on a psychiatric unit or detention-type room instead of a classroom security lever?
Asylum and institution function locks are keyed on both sides with no free egress by lever, for rooms where movement is controlled. The Dexter C1000 Series Asylum (F87) is a Grade 1 cylindrical lock for doors 1-3/8 inch to 2 inch, and the Arrow MK33-BD-CS is a Grade 2 heavy duty asylum/institution/utility lock with a ball knob and a conventional cylinder in the Schlage C keyway. The Accentra 5318LN Monroe, while also a double cylinder, is a classroom security function that keeps the inside lever free for egress at all times, which is what a school corridor code requires and a controlled room does not.
10) What lever handles an electrified access control opening if the Monroe classroom security lock will not?
An opening tied to a card reader or an access control panel needs an electrified lock. The Corbin Russwin CL33903 fail safe lever runs on 12VAC/DC and is Grade 1 for doors 1-3/4 inch to 2 inch, the same door thickness range the Accentra 5318LN Monroe is adjustable across. The 5318LN is a mechanical double cylinder classroom security lock with a brass 6-pin cylinder, so it is keyed and manual only - it will not release from a panel.
11) What finishes does the Accentra 5318LN Monroe lever come in, and which ones hold up in a school corridor?
Thirteen finishes are catalogued for the series, and ten are stocked as orderable options: 605 bright brass, 606 satin brass, 612 satin bronze, 613E dark oxidized satin bronze equivalent, 619 satin nickel, 625 bright chrome, 626 satin chrome, 693 black painted, plus black and white suede powder coat. PVD is standard on 605 and 606 and available on 613, which is what you want on high-touch classroom and corridor doors where a plated brass finish would wear through. 626 satin chrome is the usual institutional default.
12) Should I use a Grade 2 classroom security lever or step up to Grade 1 for a school?
Grade 2 covers most classroom doors in a school and is what the 5318LN carries under A156.2 Series 4000. Where the opening sees very heavy traffic, main corridors, gyms, or a door with a history of abuse, a Grade 1 classroom security lock is the better call. The Dexter C1000 Series classroom security lever is the Grade 1 equivalent function, with a clutching lever and a 1-3/8 to 1-3/4 inch door thickness range, so note it will not go on a 2 inch leaf the way the 5318LN will.
13) I only need the door locked from the outside with a key, not a classroom security lockdown. Is there a simpler lever?
If nobody needs to lock the door from inside the room, a storeroom or entry function costs you less complication and one fewer cylinder to key. The Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt for 1-3/8 to 1-3/4 inch doors, and the Hager 2580 is a Grade 2 storeroom lever covering 1-3/8 to 2 inch. Cal-Royal also lists the AG03 as a standard classroom lever, keyed outside only, if you want classroom function without the inside cylinder.
14) Can I standardize a whole building on the Accentra 5300LN Series and still get the other door functions?
Yes. The 5318LN is the classroom security member of the Accentra 5300LN Series cylindrical lever family, so the Monroe lever and rose carry across the other functions in the series and every door reads the same down the corridor. Doing it that way also keeps the keying, the 2-3/4 inch backset and the strike prep uniform, which is the point of a facility standard. Mixing brands on adjacent openings is where the strike lip lengths and backsets start disagreeing.
15) Do I need anything besides the 5318LN lock to finish a classroom door retrofit?
The lock comes complete with cylinders, two keys and the 1-1/4 inch curved lip strike, so a standard 161 bore at 2-3/4 inch backset in a 1-3/4 inch door needs nothing added. Order extras only where the opening differs: an extension link if the bore sits at 2-3/8, 3-3/4 or 5 inch backset, or a different strike lip length if the frame stop-to-edge dimension does not suit the 1-1/4 inch lip. Keyed random is standard, so if the school runs a masterkey system, that has to be specified up front rather than added later.
16) Is a keypad lever lock an alternative to the Accentra 5318LN classroom security lock?
They solve different problems. The Accentra 5318LN Monroe is a keyed double cylinder classroom security lock supplied with a brass 6-pin keyed-random cylinder and two keys, so it drops into a keyed master system. Keypad levers such as the Delaney LP250 electronic keypad leverlock, a Grade 2 unit, or the Lockey 2835DC double combination mechanical keyless lever with passage function for doors 1-3/16 inch to 2 inch, run on codes instead of keys and the Lockey units are passage function - they are not classroom security. Where a school needs a teacher to lock the door with a key from inside the room, a code-entry passage lever does not substitute.
17) What lever lock should I use on a storeroom or supply closet instead of a classroom security lock?
A storeroom function is the right call where the door must stay locked at all times and the key only lets you in. The Cal-Royal AG05 (CAL-AG05-26D) is a Grade 2 storeroom lever lockset with a deadlocking latchbolt for doors 1-3/8 inch to 1-3/4 inch thick, and the Hager 2580 with the Withnell lever (HAG-2580WTN26D) is a Grade 2 storeroom lever for doors 1-3/8 inch to 2 inch. The Accentra 5318LN Monroe is a classroom security lock, keyed from both sides, which is more lock than a supply closet needs and adds a second cylinder to key.
18) Which lever lock matches the Accentra 5318LN Monroe on the non-keyed doors in the same corridor?
Passage levers carry the corridor doors that never lock. In Grade 2, the Falcon B101 is a medium duty non-handed cylindrical passage lever, the Hager 2510 is a Grade 2 passage lever with the Withnell design for doors 1-3/8 inch to 2 inch, and the Arrow GL01 Sierra lever is a Grade 2 non-keyed passage lock rated for 1-3/4 inch to 2 inch doors - the same door thickness range the Accentra 5318LN Monroe is adjustable across. Buying the passage doors at the same grade keeps the feel of the hardware consistent down the hall.
19) What is the Grade 1 equivalent if the specification will not accept a Grade 2 lever lock?
For a Grade 1 cylindrical lever on the same 1-3/4 inch to 2 inch doors the Accentra 5318LN Monroe covers, the Corbin Russwin CL3100 Series CL3110 is a Grade 1 vandal resistant fire-rated lever in passage/closet function, and the Corbin Russwin CL33903 fail safe lever with the NZ lever and D rose is Grade 1 in the same thickness range. The Falcon K101 is a Grade 1 heavy duty fire-rated passage lever spanning 1-3/8 inch to 2-1/4 inch. All three are non-keyed or electrified rather than classroom security, so a Grade 1 spec on a classroom security opening points to the Dexter C1000 Classroom Security lever instead.
20) What lever lock should I use on an office door rather than a classroom security lock?
Entrance and office function locks let the occupant leave the outside lever locked or unlocked as they choose. The Hager 2525 is a Grade 2 commercial cylindrical entry lock with a lever for doors 1-3/8 inch to 2 inch, the Falcon B511CP6D is a Grade 2 medium duty entry/office lever, and the Cal-Royal AG00 entrance lever is Grade 2 with a 6-pin Schlage C keyway keyed different and a 2-3/8 inch backset. The Accentra 5318LN Monroe is a classroom security function with cylinders on both sides, which an office door does not require.
21) Will a knob lockset work in place of the Monroe lever on a school door?
Knob locksets such as the Arrow HK11-BB turn-pushbutton entrance lock with a ball knob and conventional cylinder for 1-3/8 inch to 1-3/4 inch doors, or the Arrow MK02-TA Tudor knob privacy lock for 1-3/4 inch to 2 inch doors, use the same cylindrical bore but a knob rather than a lever. The Accentra 5318LN Monroe uses a lever handle, which is the trim style specified where ADA operable-part requirements apply to the door. On school and public-corridor openings that is usually decisive regardless of function.
22) What is the Accentra 5318LN chassis made of, and does the lever hold up to daily classroom traffic?
The mechanism is heavy-gauge steel, zinc-plated and dichromated for corrosion resistance, with a stainless steel latchbolt. That is the construction behind the Grade 2 rating under A156.2 Series 4000, and it is what separates a commercial cylindrical lock from residential Grade 3 hardware like the Kwikset 200BRNL passage lever. For classroom doors cycling all day, the plated steel chassis and stainless latch are the parts that matter.
23) What do I order for the classroom doors that need a lever but no working lock?
Dummy trim gives you the matching lever with no latch at all, for inactive leaves and closet faces. 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 in the same style. The Callan Bentley is a Grade 2 dummy lever. Against these, the Accentra 5318LN Monroe is a working double cylinder classroom security lock with a 1/2 inch stainless steel latchbolt throw - a dummy will not latch the door.
24) Does the Monroe lever come in a decorative or residential style for administrative offices?
For a residential or decorative look on an interior office door, the Baldwin Estate 5103 lever with the 5048 rose is offered in passage, privacy, and half dummy in left and right hand, and Emtek offers dummy pairs in Arts and Crafts, Hammered, and Cortina levers. The Accentra 5318LN Monroe is a commercial Monroe lever built to ANSI/BHMA A156.2 Series 4000 Grade 2 with a UL/cUL fire rating up to 3 hours, offered in finishes including 605 bright brass, 626 satin chrome, and 693 black painted. If the door is fire rated, the commercial lock is the one that carries the label.
