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

1) What does the classroom security function on the Accentra 4718LN actually do?
The 4718LN is a double cylinder classroom security lever lock, meaning there is a keyed cylinder on both the outside and the inside. A teacher can lock or unlock the outside lever with a key from inside the room without opening the door and stepping into the corridor. The inside lever always retracts the latch for free egress. That inside-key capability is the difference between this and a standard classroom lock, where you have to key the outside cylinder from the hallway.
2) Will the Accentra 4718LN fit a 1-3/8 inch door, or only 1-3/4?
Both. The 4700LN trim adjusts from 1-3/8 inch to 1-3/4 inch, which covers standard commercial doors and the thinner older interior doors you find in school buildings. If your door runs 1-3/4 to 2 inches, that is the 4700 (non-LN) range instead, and the 4700 only comes in satin stainless steel 630.
3) Will the 4718LN drop into my existing door prep and strike?
It uses a 2-3/4 inch standard backset with a 2-1/4 x 1-1/8 inch beveled front, and ships with an ANSI strike measuring 4-7/8 x 1-1/4 inch with a 1-1/4 inch lip to center. If your frame is already prepped for an ANSI strike at a 2-3/4 backset, it lines up. The latchbolt is stainless steel with a 1/2 inch throw, so the strike pocket depth is the same as most commercial cylindrical locks. Flat fronts and an optional T-strike can be ordered for the 4700LN if your door or frame needs them.
4) Do I need to specify handing when ordering the Accentra 4718LN?
No. The 4718LN is non-handed, so one lock covers left and right hand openings. For a property manager buying a batch across a building, that means no sorting by door swing at install and a single part to stock as a spare.
5) Can I use the Accentra 4718LN on a fire-rated classroom door?
Yes. The 4700LN lever locks are UL-cUL fire rated up to 3 hours and certified to ANSI/BHMA A156.2 Series 4000 Grade 1. The guardbolt deadlocks the latchbolt when the door is closed, which is standard on every locking function in the series. The line also carries a 4700LN windstorm certification, though you should confirm against your local code for a storm shelter application.
6) What cylinder and keying comes with the Accentra 4718LN, and can I get 7-pin?
Each lock ships with a brass 6-pin keyed-random cylinder and two keys. Seven-pin is not offered in this series. Since it is a double cylinder classroom security function, there are two cylinders on the lock, so factor that into your keying schedule if you are keying alike across a school.
7) What is the closest cross-brand equivalent to the Accentra 4718LN classroom security lever lock?
The Dexter C1000 Series classroom security lever (DEX-C1000-CSEC) is the closest match. Like the Accentra 4718LN, it is a Grade 1 keyed cylindrical lever lock with the classroom security function, and it lists a door thickness range of 1-3/8 inch to 1-3/4 inch, the same range the 4718LN covers in the LN trim. The Dexter uses a clutching lever design; the Accentra 4718LN carries the Augusta lever trim and is non-handed.
8) What is the difference between a classroom lock and a classroom security lock for a school retrofit?
A standard classroom function is keyed only from the corridor side, so locking down means opening the door. Classroom security adds a second cylinder on the room side so staff lock the outside lever from inside. The Accentra 4718LN is the classroom security version. If you only need the plain classroom function, the Dexter C1000 Series classroom lever is a Grade 1 alternative, and Dexter also builds a C1000 classroom security version if you want to price the same function from another brand.
9) I need the same Augusta lever look on non-locking doors in the same corridor. What do I order?
The 4718LN is the classroom security function only. For passage and dummy openings in the same building you are into other functions or brands. Among Grade 1 cylindrical levers, the Falcon K101 passage covers 1-3/8 to 2 inch doors and is fire rated, the Corbin Russwin CL3110 passage/closet is Grade 1 and vandal resistant for 1-3/4 to 2 inch doors, and the BEST 9K Series 1DT single dummy trim is a Grade 1 non-keyed dummy. Trim appearance will not match the Augusta lever exactly across brands.
10) Is the Accentra 4718LN heavy enough for a high-traffic school corridor?
It is built for it. The mechanism is heavy-gauge steel, die cast, zinc plated and chromated, and the lockset is certified ANSI/BHMA A156.2 Series 4000 Grade 1, the highest duty level in the cylindrical lock standard. The latchbolt is stainless steel. Grade 3 residential-style levers like the Kwikset 200BRNL or Cal-Royal AUS00 are not in the same service class for a classroom door.
11) Is there a lower-cost classroom lever if the opening does not require Grade 1?
Yes. The Cal-Royal AG03 is a Grade 2 classroom lever with a 6-pin Schlage C keyway, keyed different, on a 2-3/4 inch backset, the same backset the Accentra 4718LN uses as standard. Step down in grade means stepping down in ANSI/BHMA cycle and strength class from the 4718LN, which is certified to A156.2 Series 4000 Grade 1, and the AG03 is a single-cylinder classroom function rather than the 4718LN double cylinder classroom security.
12) For a door that only needs to stay locked from the outside at all times, what is an alternative to the 4718LN?
A storeroom function lever fits that case. The Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt and a 1-3/8 inch to 1-3/4 inch door thickness range, and the Hager 2580 is a Grade 2 storeroom lever with a 1-3/8 inch to 2 inch range. Both keep the outside lever locked continuously, where the Accentra 4718LN lets a teacher key the outside lever locked or unlocked from either side.
13) Can I use a Falcon T101 or Corbin CL3110 in place of the 4718LN on a classroom door?
No. The Falcon T101 and the Corbin Russwin CL3110 are both Grade 1 cylindrical lever locks, which makes them look like peers, but both are passage function with no cylinder. The Accentra 4718LN is a keyed double cylinder classroom security lock supplied with a brass 6-pin keyed-random cylinder and two keys. Use a passage lever only where the door never needs to lock.
14) For a patient room or holding area, is the 4718LN the right function or should I look at an asylum lock?
An asylum function is the better fit where both levers must be key-controlled at all times. The Dexter C1000 asylum lock (F87) is Grade 1 with a 1-3/8 inch to 2 inch door thickness range, and the Arrow MK33-BD-CS is a heavy-duty asylum lock with a Schlage C keyway conventional cylinder. The Accentra 4718LN is a classroom security function, which keys both sides to control the outside lever but still allows free egress from inside.
15) Will a Grade 2 entrance lever like the Hager 2525 or Falcon B511 work on a classroom door instead?
Only if the door is an office rather than a classroom. The Hager 2525 is a Grade 2 commercial entry lever covering 1-3/8 inch to 2 inch doors and the Falcon B511CP6D is a Grade 2 medium-duty entry/office lever; both are locked by a pushbutton or turn from inside, not by key. The Accentra 4718LN is Grade 1 with a double cylinder classroom security function and a guarded 1/2 inch stainless latchbolt that deadlocks when the door closes.
16) What finishes does the Accentra 4718LN Augusta 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, plus black suede and white suede powder coat. The two powder coats are the ones to look at if you are matching painted door hardware rather than plated trim. The lever itself is the Augusta design.
17) Is a keypad lever like the Delaney LP250 or Lockey 2835 a substitute for the 4718LN?
They solve a different problem. The Delaney LP250 is a Grade 2 electronic keypad leverlock, and the Lockey 2835DC is a mechanical keyless lever with passage function and a 1-3/16 inch to 2 inch door thickness range. Neither carries a classroom security function. The Accentra 4718LN is a Grade 1 mechanical lock keyed on both sides so staff can lock the outside lever from within the room, which is what a classroom lockdown procedure normally specifies.
