Accentra YAL-MO-4718LN-626 – Frequently Asked Questions

1) What does the classroom security function on the Accentra 4718LN actually do?
Classroom security means the lock is keyed on both sides. A key in the outside cylinder locks or unlocks the outside lever, and a key in the inside cylinder does the same without anyone stepping into the corridor. That is the point of the double cylinder setup on the 4718LN: a teacher can lock down the door from inside the room. The lever always retracts the latch from the inside for free egress.
2) What door prep does the 4718LN lever lock need?
Standard cylindrical prep: 2-1/8 inch bore with a 2-3/4 inch backset. The front is a 2-1/4 x 1-1/8 inch beveled face as standard, with flat fronts available to order. It ships with an ANSI strike, 4-7/8 x 1-1/4 inches with a 1-1/4 inch lip to center, and an optional T-strike can be ordered for the 4700LN if your frame is prepped that way.
3) Can the 4718LN go on a fire rated classroom door?
Yes. The 4700 Series is UL-cUL fire rated up to 3 hours and carries ANSI/BHMA A156.2, Series 4000, Grade 1 certification. The guardbolt deadlocks the latchbolt when the door closes, which is standard on all locking functions in the series.
4) What is the difference between a classroom lock and a classroom security lock?
A plain classroom lock is keyed outside only, so someone has to open the door and key it from the corridor to lock down. Classroom security is keyed both sides, letting staff lock the outside lever from inside the room. The Accentra 4718LN is the classroom security version. If you only need corridor-side keying, the Dexter C1000 Series classroom lever is the Grade 1 alternative, and Dexter also builds a classroom security version of the C1000 if you want to compare two double-keyed Grade 1 options.
5) Which lock should I use on a 2 inch thick door instead of the Accentra 4718LN?
The 4718LN with Monroe LN trim adjusts from 1-3/8 inch to 1-3/4 inch, so a thicker leaf needs a different body. The Dexter C1000 Series classroom security lever lock is Grade 1 and covers 1-3/8 inch to 2 inch in its asylum version, and the Corbin Russwin CL3100 Series Grade 1 cylindrical lever is rated 1-3/4 inch to 2 inch. Confirm the function you need on the thicker-door body before ordering.
6) What is the closest cross-brand equivalent to the Accentra 4718LN classroom security lever lock?
The Dexter C1000 Series classroom security lever lock is the closest match. Both are Grade 1 keyed cylindrical lever locks with a classroom security function, and both fit doors from 1-3/8 inch to 1-3/4 inch. The Accentra 4718LN carries Monroe lever trim and a double cylinder arrangement, so both the inside and outside cylinders are keyed; the Dexter uses a clutching lever design.
7) If I need an electrified lever for a card access classroom door, what replaces the Accentra 4718LN?
The Accentra 4718LN is a mechanical keyed lock with no electrical option. For an access-control opening, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever at 12VAC/DC for 1-3/4 inch to 2 inch doors. Note the thicker door range compared with the 4718LN's 1-3/8 inch to 1-3/4 inch.
8) Do I have to specify handing when ordering the Accentra 4718LN?
No. The 4700LN is non-handed and reversible, so one part number covers left and right hand openings. The Monroe lever is set to the correct direction during install.
9) What keying comes with the Accentra 4718LN and can I get it 7-pin?
It ships with brass 6-pin cylinders, keyed random, and two keys. 7-pin is not offered on this series. Because it is a double cylinder classroom security lock, there are two cylinders per opening to account for in your keying schedule.
10) Is there another Grade 1 classroom security lever lock if the Accentra does not suit?
The Dexter C1000 Series classroom security cylindrical lever is the closest match we carry: Grade 1, keyed, clutching lever, and rated for 1-3/8 to 1-3/4 inch doors, the same thickness window the 4700LN trim covers. The clutching lever is the main functional difference to weigh, since the outside lever spins free when locked rather than staying rigid.
11) I need matching levers on the non-locking doors in the same building. What should I pair with the 4718LN?
Matching the full corridor usually means picking passage, storeroom and privacy functions from the same family so the levers look alike. Within the Accentra 4700LN series you can order other functions on the same Monroe trim, which is the cleanest match. If you are spec'ing across brands, Grade 1 passage options we carry include the Falcon K101 (1-3/8 to 2 inch doors, fire rated) and the Corbin Russwin CL3110 (1-3/4 to 2 inch doors, fire rated), though neither will visually match the Monroe lever.
12) Is the Accentra 4718LN heavy duty enough for a school corridor?
It is built for that traffic. The mechanism is heavy-gauge steel, die-cast, zinc-plated and chromated, and the lock is ANSI/BHMA A156.2 Series 4000 Grade 1, the highest cylindrical grade. The 4700LN is also Windstorm certified, which matters in jurisdictions with storm shelter requirements in schools, so check it against your local code.
13) Will a Grade 2 or Grade 3 lever lock do the same job as the 4718LN on a classroom door?
Not for the same duty cycle or function. The 4718LN is Grade 1 with double cylinder classroom security keying. Most of the Grade 2 and Grade 3 levers in the same size range are entrance or passage functions, for example the Cal-Royal AG03 classroom lever is Grade 2 with a 2-3/4 inch backset and a Schlage C keyway, and the Cal-Royal AG05 storeroom lever is Grade 2 on 1-3/8 to 1-3/4 inch doors. Those suit lighter traffic or non-lockdown openings; for a school door where staff must secure from inside, stay with the Grade 1 classroom security function.
14) What should I use for the non-locking doors in the same corridor as Accentra 4718LN classroom locks?
For doors that only need latching, a Grade 1 passage cylindrical lever keeps the duty level consistent. The Falcon K101 is a Grade 1 heavy duty passage lever, fire rated, for 1-3/8 inch to 2-1/4 inch doors, and the Dexter C1000 Series passage lever is Grade 1 non-keyed for 1-3/8 inch to 1-3/4 inch. The Accentra 4718LN itself is a keyed classroom security lock, not a passage set.
15) Can a storeroom lever be used in place of the Accentra 4718LN on a classroom door?
They behave differently. A storeroom lever such as the Cal-Royal AG05, Grade 2 with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors, or the Hager 2580 Grade 2 storeroom with Withnell lever, keeps the outside lever locked at all times and requires a key for every entry. The Accentra 4718LN classroom security function lets the outside lever be keyed locked or unlocked from either side, and its guardbolt deadlocks the latchbolt when the door is closed.
16) Is an electronic keypad lever an alternative to the Accentra 4718LN for classroom access?
It changes how access is controlled. The Accentra 4718LN is a mechanical Grade 1 cylindrical lock using brass 6-pin keyed cylinders on both faces. Keypad options include the Delaney LP250 electronic keypad leverlock, Grade 2, and the Lockey 2835DC mechanical double-combination keyless lever for 1-3/16 inch to 2 inch doors. Those are code entry rather than keyed, so they do not integrate with an existing master key system.
17) Are residential Grade 3 levers like the Kwikset Breton a substitute for the Accentra 4718LN?
No. The Kwikset 200BRNL Breton is a Grade 3 passage lever for 1-3/8 inch to 1-3/4 inch doors and the 300BRNL Breton is Grade 3 privacy; neither is keyed for classroom control. The Accentra 4718LN is an ANSI/BHMA A156.2 Series 4000 Grade 1 commercial lock, UL-cUL fire rated up to 3 hours, with a classroom security double cylinder function.
18) What is the difference between the Accentra 4718LN and an asylum function lever?
An asylum or institution lever, such as the Dexter C1000 Series asylum F87 for 1-3/8 inch to 2 inch doors or the Arrow MK33-BD-CS with a Schlage C keyway, requires a key to operate from both sides for every passage. The Accentra 4718LN double cylinder classroom security lock uses its two cylinders only to lock and unlock the outside lever, so free egress from inside is retained.
19) What finishes does the Accentra 4718LN Monroe lever come in?
Eight finish choices: 605 bright brass, 606 satin brass, 612 satin bronze, 613E dark oxidized satin bronze equivalent, 625 bright chrome, 626 satin chrome, BSP black suede powder coat, and WSP white suede powder coat. That range makes it straightforward to match existing lever hardware down a corridor. Note the thicker-door 4700 version is offered in satin stainless steel (630) only.
20) Which Grade 1 lever lock has the widest finish selection for matching existing hardware?
The Accentra 4718LN with Monroe LN trim is offered in bright brass 605, satin brass 606, satin bronze 612, dark oxidized satin bronze 613E equivalent, bright chrome 625, satin chrome 626, black suede powder coat and white suede powder coat. Grade 1 peers such as the Dexter C1000 classroom security lever and the Falcon K101 passage lever are specified by function and door thickness rather than a comparable powder coat range.
