Accentra YAL-AU-4728LN-626 – Frequently Asked Questions

1) What does the communicating function on the Accentra 4728LN lever lock actually do?
Communicating means both levers always retract the latch, with no keyed cylinder anywhere in the lock. The 4728LN is non-keyed, so it holds a door closed and lets it be opened freely from either side. It's the setup used between adjoining rooms, hotel connecting doors, and suite pass-throughs where you want a latched door but no security on it. If you need to lock the opening at all, this is the wrong function.
2) Do I have to specify handing when I order the 4728LN lever lock?
No handing to call out. The 4700LN is non-handed and reversible, so one part number works on a left or right hand door. Order by finish only.
3) Will this Accentra lever latch into the strike that's already in my frame?
It depends on what prep you have. The 4728LN uses a 2-3/4 inch backset with a 1/2 inch stainless latchbolt throw, and ships with an ANSI strike measuring 4-7/8 x 1-1/4 inches with 1-1/4 inch lip to center. If your frame is cut for a standard ANSI 4-7/8 strike, it drops in. If your existing hardware was a 2-3/8 inch backset, the cross-bore location is wrong and the door needs re-prepping. A T-strike is available to order for the 4700LN if your frame is prepped for one.
4) Can I use the Accentra 4700LN lever on a fire rated door?
Yes. The 4700LN carries UL-cUL fire ratings up to 3 hours and is ANSI/BHMA A156.2, Series 4000, Grade 1. It's also listed as 4700LN Windstorm certified, though you should check that against your local code. For a fire opening, the guardbolt deadlocks the latchbolt when the door closes, which is standard across the series.
5) My door is 2 inches thick. What Grade 1 lever should I use instead of the 4700LN?
The 4700LN tops out at 1-3/4 inches, so it won't work. For a Grade 1 non-keyed lever on a thicker door, the Corbin Russwin CL3110 passage lever covers 1-3/4 to 2 inches and is fire rated, and the Falcon K101 passage covers 1-3/8 all the way to 2-1/4 inches. The Dexter C1000 asylum function also spans 1-3/8 to 2 inches if you need a keyed function at that thickness.
6) What is a Grade 1 alternative to the Accentra 4728LN if the opening is a plain hall or closet door rather than a communicating pair?
The Accentra 4728LN is a communicating function Grade 1 cylindrical lever lock, which is intended for openings where two rooms connect. For a straightforward hall or closet door, Grade 1 passage-function cylindrical lever locks include the Falcon K101, which is Grade 1 heavy duty passage with a 1-3/8 inch to 2-1/4 inch door thickness range and a fire rating, the Falcon T101 Grade 1 heavy duty passage lever, the Dexter C1000 Grade 1 passage lever with clutching levers and a 1-3/8 inch to 1-3/4 inch door range, and the Design Hardware X75 Grade 1 passage lever for 1-3/4 inch doors. All are non-keyed like the 4728LN.
7) Which non-keyed lever lock should I use instead of the Accentra 4728LN on a door thicker than 1-3/4 inches?
The Accentra 4728LN trim adjusts from 1-3/8 inch to 1-3/4 inch doors, so a thicker leaf needs a different lock. Non-keyed lever options with wider ranges include the Falcon K101 Grade 1 passage lever at 1-3/8 inch to 2-1/4 inch, the Corbin Russwin CL3110 Grade 1 passage/closet lever rated for 1-3/4 inch to 2 inch doors, and the Hager 2510 Grade 2 passage lever at 1-3/8 inch to 2 inch. Note these are passage function rather than communicating.
8) Which lever locks look like substitutes for the Accentra 4728LN but will not work in its place?
The Accentra 4728LN is a latching non-keyed communicating lever lock with a 1/2 inch stainless steel latchbolt and guardbolt. Dummy trims look similar but have no latch at all and only pull the door: the BEST 9K 1DT Grade 1 single dummy trim, the BEST 7KC 1DT Grade 2 single dummy, the Callan Bentley Grade 2 dummy lever, and the Baldwin Estate 5103 half dummy in left and right hand. Keyed and keypad units are also not drop-in equivalents, since the 4728LN is non-keyed: examples include the Cal-Royal AG05 Grade 2 storeroom lever, the Dexter C1000 Grade 1 classroom lever, and the Lockey 2835 mechanical pushbutton keyless lever.
9) Which Grade 1 lever lock is closest to the Accentra 4728LN for a fire-rated non-keyed opening?
The Accentra 4728LN is UL-cUL fire rated up to 3 hours and non-handed, with a 2-3/4 inch backset and an ANSI 4-7/8 inch strike. The closest non-keyed Grade 1 peers with a stated fire rating are the Falcon K101 passage lever, heavy duty and non-handed with a 1-3/8 inch to 2-1/4 inch door range, and the Corbin Russwin CL3110 passage/closet lever, described as vandal resistant for 1-3/4 inch to 2 inch doors. Both are passage rather than communicating function, so confirm which side of the opening needs to operate.
10) What finishes does the Accentra 4728LN Augusta lever come in?
Eight to choose from: 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. If you're matching existing commercial openings, 626 satin chrome is the usual house standard. Note that the thicker-door 4700 chassis is satin stainless steel 630 only, so if part of your building needs the 1-3/4 to 2 inch version you won't get a finish match across both.
11) Is a Grade 1 cylindrical lever overkill for an interior communicating door?
For a low-traffic residential-style opening, yes, and a Grade 2 or 3 passage lever will do the job for less hardware. Where Grade 1 earns its place is high-cycle commercial traffic: schools, healthcare corridors, offices, multi-tenant buildings. The 4700LN mechanism is heavy-gauge steel, die-cast, zinc-plated and chromated for that duty. If you want a Grade 1 non-keyed lever but in passage rather than communicating function, the Falcon K101 and the Dexter C1000 passage are both Grade 1 passage cylindrical levers. Lighter-duty alternatives include the Hager 2510 Grade 2 passage lever and the Falcon B101 Grade 2 passage lever.
12) Does the 4728LN come with keys or a cylinder?
No cylinder and no keys on this one. The 4728LN is a non-keyed communicating lock. Keyed functions in the 4700LN series use a brass 6-pin keyed-random cylinder with two keys furnished; 7-pin is not offered anywhere in the series, so if your facility is standardized on a 7-pin system this family won't join it.
13) The Accentra 4728LN uses a 2-3/4 inch backset. What if my door is prepped for 2-3/8 inch?
The Accentra 4728LN is supplied with a 2-3/4 inch standard backset. For a door already bored on a 2-3/8 inch backset, the Cal-Royal AG00 entrance lever is a Grade 2 lever with a 6-pin Schlage C keyway keyed different and a 2-3/8 inch backset for 1-3/8 inch to 1-3/4 inch doors. By comparison the Cal-Royal AG03 classroom lever from the AG series uses a 2-3/4 inch backset like the Accentra. The Lockey 1150 keypad lever set is offered in an adjustable backset version.
14) Is there a lower-cost lever lock comparable to the Accentra 4728LN for light-traffic interior doors?
The Accentra 4728LN is ANSI/BHMA A156.2 Series 4000 Grade 1 with a heavy-gauge die-cast mechanism, built for high-traffic commercial use. Where a lighter duty rating suits the opening, Grade 2 non-keyed lever options include the Falcon B101 medium duty passage lever with a non-handed design, the Design Hardware J75 Grade 2 passage lever for 1-3/4 inch doors, the Hager 2510 Grade 2 passage lever at 1-3/8 inch to 2 inch, and the Arrow GL01 Grade 2 passage lever with a Sierra lever for 1-3/4 inch to 2 inch doors. Grade 3 lever sets such as the Kwikset 200BRNL Breton passage and the Callan Asheville passage are residential-duty.
15) If the opening needs privacy or locking instead of the passage action of the Accentra 4728LN, what should I order?
The Accentra 4728LN is a communicating passage function lever with no locking on the 4728LN itself. For a bed or bath door that has to lock from inside, the Hager 2540 Grade 2 privacy lever with a Withnell lever handles 1-3/8 inch to 2 inch doors, the Arrow MK02-TA privacy lock uses a Tudor knob and is fire rated, and the Baldwin Estate 5103 privacy lever with 5048 rose covers decorative openings. For keyed control, the Hager 2580 Grade 2 storeroom lever and the Cal-Royal AG05 Grade 2 storeroom lever with deadlocking latchbolt both cover 1-3/8 inch to 2 inch and 1-3/8 inch to 1-3/4 inch doors respectively.
16) For a behavioral health or institutional opening, is the Accentra 4728LN the right lever or should I look at an asylum function lock?
The Accentra 4728LN is a Grade 1 communicating passage lever, not a keyed institutional function. Asylum and utility function locks, which are keyed on both sides, include the Dexter C1000 asylum (F87) Grade 1 lever for 1-3/8 inch to 2 inch doors and the Arrow MK33-BD-CS asylum lock with a ball knob and a conventional Schlage C keyway cylinder. Classroom security is a separate function again, covered by the Dexter C1000 classroom security Grade 1 clutching lever for 1-3/8 inch to 1-3/4 inch doors.
17) I need keyless code entry rather than the Accentra 4728LN. What lever locks cover that?
The Accentra 4728LN is a mechanical non-keyed communicating lever with no code entry. For pushbutton code access on a lever, the Lockey 2835 mechanical pushbutton keyless lever lock has passage function and ADA compliance for 1 3/16 inch to 2 inch doors, the Lockey 2835DC adds a double combination over the same door range, and the Lockey 1150 heavy duty keypad lever set covers 1-1/8 inch to 2 inch doors with an adjustable backset version available. Electronic keypad lever options include the Delaney LP250 Grade 2 and the Emtek Classic keypad leverset.
18) Can the Accentra 4728LN be used as lever trim on an exit device, or do I need a different part?
No. The Accentra 4728LN is a complete Grade 1 cylindrical lever lockset for a bored door prep, not exit device trim. For pushpad exit devices, the Corbin Russwin 585F715 is a Grade 1 lock lever built for the ED8000 pushpad exit device and the CL3300 cylindrical lock series, covering 1-3/4 inch to 2 inch doors, and the Imperial USA ED-EL500HD is a heavy duty escutcheon lever trim with entry function from the ED-500 series.
19) Is the front on the Accentra 4700LN beveled or flat?
Beveled as standard, 2-1/4 x 1-1/8 inches. Flat fronts are available to order if your door edge or existing mortise calls for one. Check what's cut into the door edge now before you order, because swapping the front is an order-time decision, not a field fix.
20) Can I match the Augusta lever on a communicating door to a dummy lever on the adjacent opening?
Not within this product. The 4728LN is the Augusta trim communicating lever only. For a dummy trim on a companion opening at the same grade, BEST offers the 9K Series 1DT single dummy in Grade 1, or the 7KC Series 1DT in Grade 2. Those are different lever designs, so they won't visually match Augusta, but they match on duty level.
