Accentra YAL-MO4722LN-626 – Frequently Asked Questions

1) What does the corridor function on the Accentra 4722LN lever lock actually do?
Corridor function (also called dormitory function) on the Accentra 4722LN means the outside lever is locked and unlocked by key, and the inside lever always retracts the latch for free egress. It is a single-cylinder keyed lock, so all control is from the key side plus the inside lever. It is the function property managers use on apartment corridor doors and schools use on hallway openings where the door needs to be secured with a key and stay that way until keyed again.
2) Will the 4722LN fit a 1-3/8 inch door, or does it need a 1-3/4 inch door?
Both. The 4700LN chassis with the LN (Monroe) trim adjusts from 1-3/8 inches to 1-3/4 inches, so it covers the standard commercial 1-3/4 inch door and the thinner 1-3/8 inch doors common on older interior openings. If your door is thicker than 1-3/4 inches, up to 2 inches, that is the 4700 version rather than the 4700LN, and that one only comes in satin stainless steel (630).
3) Do I need to specify handing when I order the Accentra 4722LN?
No handing to specify. The 4722LN is non-handed and the latch is reversible in the field, so one part number covers left and right hand openings. For a property manager buying a dozen at a time, that means no sorting on the truck and no wrong-hand returns.
4) Will the 4722LN latch into the strike already in my frame?
It depends on what prep is in the frame. The 4722LN ships with an ANSI strike, 4-7/8 x 1-1/4 inches with a 1-1/4 inch lip-to-center, which is the standard commercial hollow metal frame cutout. The latchbolt has a 1/2 inch stainless steel throw. If the existing frame carries a full 4-7/8 inch ANSI prep you can reuse it; if the frame has an older T-strike prep, Accentra offers an optional T-strike for the 4700LN so you do not have to cut the frame.
5) Can I put the Accentra 4722LN on a 3-hour fire rated corridor door?
Yes. The 4700LN series lever locks are UL and cUL fire rated up to 3 hours, and the guardbolt deadlocks the latchbolt whenever the door is closed, which is standard on every locking function in the series. The lock is also ANSI/BHMA A156.2 Series 4000 Grade 1, the heaviest cylindrical classification, and the 4700LN carries a windstorm certification (verify against your local code for the specific opening).
6) What cylinder comes in the 4722LN, and can I get it in 7-pin for my existing keyway?
Standard is a brass 6-pin, keyed-random cylinder with two keys furnished. A 7-pin cylinder is not available on the 4700LN series, so if your building is keyed on a 7-pin system this lock will not suite into it as shipped. Keyed-random also means each lock arrives on its own key, so if you need them alike or on a master, that has to be handled at order.
7) My door is 2 inches thick. Can I still use the 4722LN?
Not with the LN trim. The 4700LN tops out at 1-3/4 inches. For a 2 inch door you would need the 4700 version, which adjusts 1-3/4 to 2 inches but is only offered in satin stainless steel (630). If the finish has to match brass or chrome trim elsewhere in the building, look at a Grade 1 cylindrical rated for thicker doors instead, such as the Falcon K101 (1-3/8 to 2-1/4 inches) or the Corbin Russwin CL3110 (1-3/4 to 2 inches).
8) What is a Grade 1 alternative to the Accentra 4722LN corridor lever for a classroom door instead of a corridor opening?
For a classroom opening, the Dexter C1000 series classroom cylindrical lever lock is a Grade 1 keyed lever with a clutching mechanism and a 1-3/8 inch to 1-3/4 inch door thickness range, matching the 1-3/8 inch to 1-3/4 inch range the 4722LN covers. The Accentra 4722LN is a corridor function lock, so it will not provide classroom function. Dexter also offers a Grade 1 classroom security version in the same C1000 series with the same 1-3/8 inch to 1-3/4 inch door range.
9) I need a Grade 1 lever on a door that does not need to lock. What pairs with the Accentra 4722LN?
The 4722LN is a keyed corridor function lock with a single cylinder, so it always locks. For a non-locking opening on the same run of doors, Grade 1 passage levers include the Falcon K101, a heavy duty non-keyed cylindrical passage lock with non-handed levers and a 1-3/8 inch to 2-1/4 inch door thickness range; the Falcon T101, a Grade 1 heavy duty passage lever; the Dexter C1000 passage, Grade 1 non-keyed with clutching and a 1-3/8 inch to 1-3/4 inch range; and the Design Hardware X75 flat lever passage set, Grade 1 for 1-3/4 inch doors. The 4722LN is non-handed as well, so handing does not need to be matched.
10) I need electric access control on a corridor door instead of the Accentra 4722LN. What cylindrical lever handles that?
The 4722LN is a mechanical keyed corridor lock with no electrified option in the 4700LN family. For an electrified cylindrical lever on the same door type, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified lever operating on 12VAC/DC and rated for 1-3/4 inch to 2 inch doors, available with the NZ lever and D rose. Fail safe unlocks on loss of power, which is a different security posture than a mechanical corridor lock, so confirm it against the egress and life-safety requirements for the opening.
11) What is the closest lever lock to the Accentra 4722LN for a Schlage C keyway keying system?
The 4722LN comes with a brass 6-pin keyed-random cylinder and two keys standard, with 7-pin not available. If the building keys on Schlage C, the Cal-Royal AG03 classroom lever is a Grade 2 set with a 6-pin Schlage C keyway keyed different and a 2-3/4 inch backset, matching the 2-3/4 inch standard backset on the 4722LN, and the Cal-Royal AG00 entrance lever is Grade 2 with the 6-pin Schlage C keyway on a 2-3/8 inch backset and a 1-3/8 inch to 1-3/4 inch door range. Note that backset difference before ordering.
12) What finishes does the Accentra 4722LN Monroe lever come in?
The Monroe lever trim is offered in bright brass (605), satin brass (606), satin bronze (612), dark oxidized satin bronze equivalent (613E), bright chrome (625), satin chrome (626), black suede powder coat (BSP), and white suede powder coat (WSP). Satin chrome (626) is the usual choice when you are matching existing commercial hardware across a facility; the suede powder coats are there when the spec calls for painted black or white trim.
13) Is a cylindrical lever lock like the 4722LN the right choice, or should I be looking at a mortise lock?
A cylindrical lock like the 4722LN bores through the door with a cross bore and edge bore, so it is quicker to install and easier to retrofit than a mortise lock, which needs a pocket routed into the door edge. For corridor and dormitory doors in offices, schools, healthcare, and multi-tenant residential, a Grade 1 cylindrical is the normal spec and this one meets the top ANSI/BHMA cylindrical classification. Go mortise when the opening needs a deadbolt plus latch in one case or a function a bored lock cannot provide.
14) What are my options if I need a Grade 1 lever lock but the 4722LN corridor function is wrong for the door?
Match the function to the opening. For a hallway or closet door that never locks, the Dexter C1000 passage lever is Grade 1 and covers 1-3/8 to 1-3/4 inch doors, and the Falcon K101 Grade 1 passage is fire rated with a wider 1-3/8 to 2-1/4 inch thickness range. For a classroom door keyed from the outside, the Dexter C1000 classroom is Grade 1 at the same 1-3/8 to 1-3/4 inch range. For a vandal-resistant passage on a thicker door, the Corbin Russwin CL3110 is Grade 1, fire rated, 1-3/4 to 2 inches.
15) Is a Grade 2 lever lock good enough for an apartment corridor, or do I need Grade 1 like the 4722LN?
Grade 1 is the heaviest ANSI/BHMA cylindrical classification and is what gets specified on high-traffic commercial corridors, schools, and healthcare. The 4722LN is Grade 1 with a heavy-gauge steel, die-cast, zinc-plated and chromated mechanism. Grade 2 lever locks such as the Hager 2525 entry or the Falcon B511CP6D entry/office are medium-duty alternatives that suit lighter-traffic tenant-side or office doors. Grade 3, like the Cal-Royal AUS00, is residential-level duty and not what you want on a shared corridor.
16) What comes in the box with the Accentra 4722LN, and what do I still need to order?
Each 4722LN ships with the lock chassis, Monroe lever trim both sides, the latch with a 1/2 inch throw and guardbolt, the ANSI strike, and a 6-pin brass cylinder with two keys. Nothing extra is required for a standard hollow metal opening prepped to 2-3/4 inch backset. Order separately only if you need a flat front instead of the standard beveled 2-1/4 x 1-1/8 inch front, or the optional T-strike for an older frame prep.
17) What is a lighter-duty lever lock than the Accentra 4722LN for a lower-traffic opening?
The Accentra 4722LN is ANSI/BHMA A156.2 Series 4000 Grade 1. Grade 2 cylindrical levers in the same style include the Hager 2525 commercial entry lock and Hager 2580 storeroom lock with Withnell lever, both rated for 1-3/8 inch to 2 inch doors, the Cal-Royal AG05 Grade 2 storeroom lever with deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors, and the Falcon B511CP6D Grade 2 medium duty entry/office lever. Grade 2 sets are tested to a lower cycle and strength threshold than Grade 1, and none of those functions is corridor, so verify the function suits the opening before substituting.
18) Is a dummy lever trim a substitute for the Accentra 4722LN on an inactive leaf?
No. The 4722LN is a keyed corridor function cylindrical lock with a latchbolt and guardbolt, so it latches and locks. Dummy trim has no latch at all and is for a fixed or inactive leaf. If that is what the opening needs, the BEST 9K series 1DT single dummy trim lever is Grade 1 heavy duty non-keyed, and the BEST 7KC series 1DT single dummy is the Grade 2 medium duty equivalent. Do not order dummy trim expecting it to secure a corridor door.
19) What should I use instead of the Accentra 4722LN if I want keyless code entry on the door?
The 4722LN uses a brass 6-pin keyed cylinder with two keys furnished, so access is by key. For code entry on a cylindrical lever prep, the Lockey 1150 heavy duty mechanical keypad lever set covers 1-1/8 inch to 2 inch doors, the Lockey 2835 mechanical pushbutton keyless lever lock covers 1-3/16 inch to 2 inch doors, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. Those are mechanical or electronic code sets rather than corridor function keyed locks.
20) Is a lever lock trim for an exit device an alternative to the Accentra 4722LN?
No, they solve different openings. The 4722LN is a complete Grade 1 cylindrical lever lock with its own latchbolt, guardbolt, and ANSI strike. The Corbin Russwin 585F715 is a Grade 1 lock lever for the ED8000 pushpad exit device in the CL3300 cylindrical lock series, rated for 1-3/4 inch to 2 inch doors, and the Imperial USA ED-EL500HD is heavy duty escutcheon lever trim with entry function. Both of those are trim for a device already on the door, not a standalone lockset.
21) For a patient room or utility door, what replaces the corridor function of the Accentra 4722LN?
Corridor function on the 4722LN locks and unlocks the outside lever by key. For an asylum or institutional utility opening where both levers stay locked and are always key operated, the Dexter C1000 series asylum lock is Grade 1 with a 1-3/8 inch to 2 inch door range, and the Arrow MK33-BD-CS is a heavy duty asylum, institution and utility function lock with a conventional Schlage C keyway cylinder on a ball knob rather than a lever.
22) What is a privacy lever to pair with the Accentra 4722LN for restrooms on the same floor?
The 4722LN is a keyed corridor lock and does not offer a thumbturn privacy function. For restroom and bedroom doors, the Hager 2540 with Withnell lever is a Grade 2 cylindrical privacy lock for 1-3/8 inch to 2 inch doors, the Kwikset 300BRNL RDT Breton is a Grade 3 privacy lever for 1-3/8 inch to 1-3/4 inch doors, and the Baldwin Estate 5103 privacy lever with 5048 rose is a decorative option. The Accentra lever design is the Monroe lever, so trim styling will not match across those brands.
