Accentra YAL-MO4739LN-626 – Frequently Asked Questions

1) What does the communicating function on the Accentra 4739LN lever lock actually do?
Communicating function means the lock is keyed on both sides and either key retracts the latch, so the opening can be controlled from both rooms. That is what separates the 4739LN from a classroom lock, where only the outside is keyed. It is the function to use on a door between two adjoining spaces, such as connecting hotel rooms, adjoining offices, or two classrooms sharing a door, where staff on either side need key control. Note that communicating locks have no deadlocking fail-safe egress behavior of a classroom or storeroom function, so check your local egress code for the opening before specifying one.
2) Will the Accentra 4739LN fit a 1-3/8 inch door, or does it need a 1-3/4?
Both. The 4700LN is adjustable from 1-3/8 to 1-3/4 inches, so it covers the common older interior door as well as the standard commercial 1-3/4. If your doors run thicker, 1-3/4 to 2 inches, that is the plain 4700 body rather than the LN, and the 4700 only comes in satin stainless steel 630.
3) Does the 4739LN lever lock need to be handed when I order it?
No handing to specify. The 4700LN is non-handed and reverses in the field, so one part number covers left and right hand openings. That makes it easier to stock across a building where the door swings vary.
4) Can I use the Accentra 4739LN on a fire rated door?
Yes. The 4700LN is UL-cUL fire rated up to 3 hours, which covers most rated corridor and stair openings. It is also certified ANSI/BHMA A156.2 Series 4000 Grade 1 and carries 4700LN windstorm certification, though you should confirm windstorm against your local code.
5) What cylinder and keying comes with the Accentra 4739LN, and can I get 7-pin?
It ships with a brass 6-pin keyed-random cylinder and two keys. Because it is a communicating function, there are cylinders on both sides. 7-pin is not available on this lock, so if your facility standard is a 7-pin master key system, this body will not join that keying scheme without a change of approach.
6) I need a classroom lock, not a communicating one. What should I order instead?
If only the outside needs key control and the inside always stays free egress, you want a classroom function, not the 4739LN communicating. Within the same Accentra 4700LN line the classroom function is the sibling model with the same 2-3/4 backset and Monroe trim. Across brands we carry, the Dexter C1000 Series classroom lever is Grade 1 with a clutching lever and a 1-3/8 to 1-3/4 inch door thickness range, and the Cal-Royal AG03 is a Grade 2 classroom lever on a 2-3/4 inch backset with a 6-pin Schlage C keyway. If you need the teacher to lock the door from inside during a lockdown, look at the Dexter C1000 classroom security version, which is keyed both sides for that purpose.
7) What is the closest Grade 1 classroom cylindrical lever lock to the Accentra 4739LN?
The Dexter C1000 Series classroom lever lock (DEX-C1000-CLRM) is the closest equivalent: it is a Grade 1 cylindrical lever lock with a keyed classroom function and a 1-3/8 inch to 1-3/4 inch door thickness range, matching the 4739LN's 1-3/8 inch to 1-3/4 inch adjustment on the 4700LN trim. The Dexter uses a clutching lever design, while the 4739LN carries the Monroe lever trim and a communicating classroom function.
8) The door is 1-3/4 to 2 inches thick. What Grade 1 lever fits instead?
The Corbin Russwin CL3110 vandal resistant cylindrical lever lock is a Grade 1, fire-rated passage/closet lock covering 1-3/4 inch to 2 inch doors, and the Falcon K101 Grade 1 heavy duty passage lever spans 1-3/8 inch to 2-1/4 inch. Note both are non-keyed passage functions. On the Accentra side, the 4700 trim is adjustable from 1-3/4 inch to 2 inch while the 4700LN trim covers 1-3/8 inch to 1-3/4 inch.
9) Which classroom-family lock should I use where the teacher needs to lock the corridor door from inside?
The Dexter C1000 classroom security lever (DEX-C1000-CSEC) is a Grade 1 clutching keyed lock with a classroom security function for 1-3/8 inch to 1-3/4 inch doors, which is the lockdown-from-inside arrangement. The Accentra 4739LN is a communicating classroom function, which addresses a pair of connected rooms rather than corridor lockdown, so confirm which behavior the door schedule calls out.
10) What keeps the latch from being carded or shimmed on the 4739LN?
A guardbolt sits alongside the latch and deadlocks it as soon as the door closes, which blocks loiding with a card or shim. It is standard on all locking functions in the 4700 line, including the 4739LN communicating.
11) Is the Accentra 4739LN heavy duty enough for a school corridor?
It is built for it. ANSI/BHMA A156.2 Series 4000 Grade 1 is the top commercial cycle and strength tier, and the mechanism is heavy-gauge steel, die cast, zinc plated and chromated for corrosion resistance. Grade 1 is what most school districts, hospitals and government facilities specify as a minimum for high traffic openings.
12) What are my Grade 1 alternatives to the Accentra 4739LN if the finish or lever design doesn't match my building?
Several Grade 1 cylindrical levers we carry sit in the same class. The Corbin Russwin CL3100 Series is Grade 1 and fire rated but fits 1-3/4 to 2 inch doors, so it is the one to look at if your doors are thicker than the 4700LN's 1-3/8 to 1-3/4 range. The Falcon K Series is Grade 1, heavy duty, fire rated, with an unusually wide 1-3/8 to 2-1/4 inch thickness range. The Dexter C1000 Series is Grade 1 across 1-3/8 to 1-3/4 inches. Bear in mind these peers are listed here in non-keyed or other functions, so match the function you need before substituting.
13) Is a Grade 3 residential lever like the Kwikset Breton an acceptable substitute for the Accentra 4739LN?
No, and not for the same opening. The 4739LN is a Grade 1 commercial lock certified to ANSI/BHMA A156.2 Series 4000 and UL fire rated to 3 hours. The Kwikset 200BRNL Breton is a Grade 3 passage lever, non-keyed, for interior hall and closet duty on 1-3/8 to 1-3/4 inch doors. Grade 3 will not carry a commercial corridor or a rated opening. If you want a middle option for lower traffic commercial interiors, the Hager 2525 is a Grade 2 cylindrical entry lever covering 1-3/8 to 2 inch doors.
14) We need a classroom lever but not at Grade 1 duty. What else works?
The Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt on a 1-3/8 inch to 1-3/4 inch door, and the Cal-Royal AG03 classroom lever in the AG Series uses a 6-pin Schlage C keyway with a 2-3/4 inch backset, the same backset the Accentra 4739LN uses as standard. The 4739LN is ANSI/BHMA A156.2 Series 4000 Grade 1 and ships with a brass 6-pin keyed-random cylinder.
15) Is a Falcon B511 or Hager 2525 entry lever an acceptable substitute for the Accentra 4739LN?
They serve a different opening. The Falcon B511CP6D is a Grade 2, medium duty entry/office cylindrical lever and the Hager 2525 is a Grade 2 commercial entry lever for 1-3/8 inch to 2 inch doors. The Accentra 4739LN is a Grade 1 lock with a communicating classroom function, so an entry/office lever will not reproduce the communicating keying arrangement or the Series 4000 Grade 1 cycle rating.
16) What should I use on the doors in the same classroom suite that do not need to lock?
For the non-locking leaves, the Dexter C1000 Grade 1 non-keyed passage lever covers 1-3/8 inch to 1-3/4 inch doors, the same thickness range the Accentra 4700LN trim adjusts through, and the Design Hardware X75 is a Grade 1 flat-lever passage set for 1-3/4 inch doors. For dummy trim on inactive leaves, the BEST 9K Series 1DT is a Grade 1 heavy duty single dummy cylindrical lever trim.
17) Would a keypad lever lock replace the Accentra 4739LN on a classroom door?
Not on a like-for-like basis. The Lockey 2835 mechanical pushbutton keyless lever lock has a passage function and fits 1 3/16 inch to 2 inch doors, and the Delaney LP250 electronic keypad leverlock is Grade 2. The Accentra 4739LN is keyed, Grade 1, and UL-cUL fire rated up to 3 hours, so on a fire-rated classroom opening the keyless units are a different specification rather than a swap.
18) Is the Arrow MK33 asylum lock the same thing as a communicating lock?
No. The Arrow MK33-BD-CS is a Grade 2 heavy duty asylum/institution/utility cylindrical lock with a ball knob and a conventional Schlage C keyway cylinder, and the Dexter C1000 F87 asylum lock is the Grade 1 version of that function for 1-3/8 inch to 2 inch doors. Asylum function keys both sides; the Accentra 4739LN is a communicating classroom lock with a lever handle and a 1/2 inch stainless steel latchbolt.
19) What finishes does the Accentra 4739LN Monroe lever come in?
Eight choices: 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 BSP, and white suede powder coat WSP. Satin chrome 626 is the usual commercial default if you are matching existing school or office hardware; the two powder coats are the ones to look at when you are matching painted or dark storefront trim.
20) Can I match the Accentra 4739LN finishes with another commercial lever line?
The 4739LN in the 4700LN trim is offered in eight finish choices including 605 bright brass, 606 satin brass, 612 satin bronze, 625 bright chrome, 626 satin chrome, and black and white suede powder coats. If you are mixing lines on the same corridor, the Bravura Miramar passage leverset is catalogued in US4 satin brass at Grade 2, which is the closest published finish callout among the lighter-duty levers.
