Accentra YAL-AU4739LN-626 – Frequently Asked Questions

1) What does the communicating function on the Accentra 4739LN lever lock actually do?
The 4739LN is a communicating function lock, meaning it is keyed on both sides and is used on a door between two spaces (adjoining hotel rooms, connected offices, patient suites) where either side needs key control over the other. It is a cylindrical lever lock in the Accentra 4700LN Series with Augusta lever trim, ANSI/BHMA A156.2 Series 4000 Grade 1.
2) Will the Accentra 4700LN lever lock fit a 1-3/4 inch commercial door?
Yes. The 4700LN is adjustable from 1-3/8 inch to 1-3/4 inch, so it covers standard 1-3/4 inch commercial doors and the thinner 1-3/8 inch openings you still find in older interior work. If your door runs thicker, 1-3/4 inch up to 2 inch, that is the 4700 (non-LN) range instead.
3) Will the 4739LN latch into the strike already in my frame?
It ships with a 1/2 inch stainless steel latchbolt throw and a standard ANSI strike, 4-7/8 x 1-1/4 inches with a 1-1/4 inch lip to center. If your frame is already prepped for an ANSI 4-7/8 inch strike, it drops straight in. Non-ANSI frames with a small T-strike cutout are covered too: an optional T-strike is available to order for the 4700LN.
4) Is the Accentra 4700LN lever lock non-handed, and what backset does it use?
Non-handed, so one lock covers left and right hand openings and you do not have to specify handing on the order. Backset is 2-3/4 inches standard, which is the usual commercial bore location.
5) Can I use the Accentra 4739LN on a fire-rated door?
Yes. The 4700LN Series carries UL-cUL fire ratings up to 3 hours. It is also listed as Windstorm certified in the 4700LN configuration, though you should work to your local code on that.
6) How does the 4739LN come keyed, and can I get it in a 7-pin cylinder?
Standard is a brass 6-pin keyed-random cylinder with two keys furnished. A 7-pin cylinder is not offered on this series, so if your facility is standardized on 7-pin large format interchangeable core, this is not the lock to spec.
7) What is the closest Grade 1 cylindrical lever alternative to the Accentra 4739LN if I need a classroom function instead of communicating?
The Accentra 4739LN is a Grade 1 cylindrical lever lock with a communicating function, meaning both sides operate independently for a door connecting two occupied spaces. If the opening actually calls for classroom function, the Dexter C1000 Series classroom lever is a Grade 1 cylindrical lever lock with classroom function and a 1-3/8 inch to 1-3/4 inch door thickness range, matching the 4739LN's adjustable 1-3/8 inch to 1-3/4 inch range. For a classroom security variant with key control on both sides, the Dexter C1000 Series classroom security lock is also Grade 1 cylindrical with the same 1-3/8 inch to 1-3/4 inch range.
8) Would an Arrow MK33 asylum lock or Dexter C1000 asylum lock work in place of the Accentra 4739LN communicating lock?
They are close in intent but not the same. Asylum function, like the Arrow MK33-BD-CS heavy duty Grade 2 asylum cylindrical lock and the Dexter C1000 Grade 1 asylum lock with a 1-3/8 inch to 2 inch door range, requires a key on both sides to operate at all times. The Accentra 4739LN communicating function allows free operation from each side with key control, so on an opening where the drawing calls for communicating, an asylum lock changes how occupants pass through the door. Also note the Arrow MK33 uses a ball knob rather than a lever.
9) What finishes does the Accentra 4739LN 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 BSP black suede powder coat and WSP white suede powder coat. The powder coat options are useful when you are matching painted hollow metal rather than plated hardware.
10) What is the guardbolt on this cylindrical lock for?
The guardbolt deadlocks the latchbolt whenever the door is closed, which stops the latch being carded or shimmed open. It is standard on all locking functions in the 4700LN Series, including the 4739LN communicating lock.
11) Does the Accentra 4700LN come with a beveled or flat front?
A 2-1/4 x 1-1/8 inch beveled front is supplied standard. Flat fronts are available to order if your door edge prep or existing latch face calls for one.
12) What Grade 1 cylindrical lever locks compare to the Accentra 4700LN?
For Grade 1 cylindrical levers, the Dexter C1000 Series covers the same 1-3/8 to 1-3/4 inch door range in classroom, classroom security and passage functions, and the Falcon K Series K101 is a Grade 1 heavy duty fire-rated passage lever with a wider 1-3/8 to 2-1/4 inch range. Corbin Russwin's CL3100 Series CL3110 is Grade 1 and fire rated but built for thicker 1-3/4 to 2 inch doors. None of those are communicating function, so if you specifically need keyed control from both sides on an adjoining door, the 4739LN is the one to hold.
13) Is there a lighter-duty lever I can use on interior doors instead of the Grade 1 Accentra 4739LN?
Yes. The 4739LN is an ANSI/BHMA Grade 1 commercial cylindrical lever. For lower-traffic interior openings, the Hager 2510 is a Grade 2 cylindrical passage lever with the Withnell design and a 1-3/8 inch to 2 inch door thickness range, and the Falcon B101 is a Grade 2 medium duty cylindrical passage lever with a non-handed design. The Accentra 4739LN is also non-handed. Keep in mind those Grade 2 options are passage function with no keyed control, unlike the communicating function of the 4739LN.
14) What is the difference between the Accentra 4739LN and a storeroom lever like the Cal-Royal AG05 or Hager 2580?
Function is the difference. The Accentra 4739LN is a Grade 1 communicating cylindrical lever, used where a door between two spaces needs to be controlled from either side. 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 range, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever and a 1-3/8 inch to 2 inch range. Storeroom function keeps the outside lever locked at all times, which is not interchangeable with a communicating opening.
15) I need matching trim on a non-functioning door next to my Accentra 4739LN openings - what do I order?
A dummy trim gives the same lever appearance with no latch. The BEST 9K Series 1DT is a Grade 1 non-keyed heavy duty single dummy trim cylindrical lever, which matches the Grade 1 level of the Accentra 4739LN, and the BEST 7KC Series 1DT is a Grade 2 medium duty single dummy trim lever. Neither carries the Augusta lever design of the 4739LN, so if visual match across the suite matters, confirm the lever style before ordering.
16) If I want keyless entry instead of the keyed Accentra 4739LN, what lever options are there?
The Accentra 4739LN uses a brass 6-pin keyed cylinder with two keys furnished. For code-based access with no keys to manage, the Lockey 2835 mechanical pushbutton keyless lever lock is ADA compliant and fits doors from 1 3/16 inch to 2 inch, and the Lockey 1150 heavy duty mechanical keypad lever set covers 1-1/8 inch to 2 inch with an adjustable backset. The Delaney LP250 is an electronic keypad leverlock at Grade 2. None of these provide the two-sided communicating function of the 4739LN.
17) I need an electrified lever on the same door series as the Accentra 4739LN - what should I look at?
The Accentra 4739LN is a mechanical Grade 1 cylindrical lever with no electrified option in the 4700LN line. For access control tie-in, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever operating on 12VAC/DC with a 1-3/4 inch to 2 inch door thickness range. Because that range starts at 1-3/4 inch, verify your door is at the upper end of the 1-3/8 inch to 1-3/4 inch range the 4700LN covers before swapping it in.
18) Does a decorative lever like the Baldwin Estate 5103 or Deltana Manchester substitute for the Accentra 4739LN?
Not on a commercial opening. The Accentra 4739LN is an ANSI/BHMA A156.2 Series 4000 Grade 1 cylindrical lever, UL-cUL fire rated up to 3 hours with a 2-3/4 inch backset and a 1/2 inch stainless steel latchbolt throw. The Baldwin Estate 5103 with the 5048 rose is offered in passage, privacy and half dummy functions, and the Deltana 6201 Manchester is an entry lever for doors 1-3/8 inch to 2 inch thick. Those are decorative entry and interior trims and none carries a communicating function, so they are a styling choice rather than a spec-for-spec replacement.
19) What Grade 1 passage lever pairs with Accentra 4739LN communicating locks on the same corridor?
For non-locking openings alongside 4739LN communicating doors, the Dexter C1000 Grade 1 passage cylindrical lever is clutching and non-keyed with a 1-3/8 inch to 1-3/4 inch door range that matches the 4700LN adjustment range. The Design Hardware X75 is a Grade 1 passage lever lockset with a flat lever for 1-3/4 inch doors, and the Falcon T101 is a Grade 1 heavy duty passage lever with pressure release technology. All three hold the same ANSI grade as the 4739LN.
20) Is a Grade 1 lever like the 4700LN overkill for a light-traffic interior door?
For a closet, hall or low-traffic interior door you rarely need Grade 1 cylindrical hardware. Grade 2 passage levers such as the Hager 2510 (1-3/8 to 2 inch doors) or the Falcon B Series B101 non-handed passage lever handle that duty. Save the 4700LN Grade 1 build for high-cycle commercial openings and anywhere fire rating and keyed control matter.
21) What is the lock mechanism on the Accentra 4700LN made of?
Heavy-gauge steel, die-cast, zinc-plated and chromated through the mechanism, with a stainless steel latchbolt. That is the construction behind the Grade 1 rating and the reason it holds up on high-cycle openings in schools, healthcare and multi-tenant buildings.
22) What is a residential-grade alternative to the Accentra 4739LN for apartment interior doors?
The Accentra 4739LN is a Grade 1 commercial cylindrical lever. For residential interior openings, the Kwikset 200BRNL Breton passage lever is a Grade 3 passage lock covering 1-3/8 inch to 1-3/4 inch doors, and the Kwikset 300BRNL Breton privacy lever is a Grade 3 privacy lock over the same 1-3/8 inch to 1-3/4 inch range. The Cal-Royal AUS00 is a Grade 3 entrance/office lever with a solid brass forged body, also 1-3/8 inch to 1-3/4 inch. These are non-communicating functions and carry a lower ANSI grade than the 4739LN.
