Accentra YAL-AU4722LN-626 – Frequently Asked Questions

1) What does the corridor function on the Accentra 4722LN lever lock actually do?
Corridor function, sometimes called dormitory function on other brands. The 4722LN is a keyed single-cylinder cylindrical lever lock: the key locks and unlocks the outside lever, and the guardbolt deadlocks the latchbolt whenever the door is closed so it can't be shimmed. It's the function specified where a corridor or suite door has to be left unlocked during the day and secured with a key after hours. If you want a door that stays locked outside at all times and always releases from inside, a storeroom lock like the Cal-Royal AG05 is the right function instead.
2) Will the Accentra 4722LN fit a 1-3/8 inch door, or does it need a 1-3/4 inch door?
Both. The 4722LN adjusts from 1-3/8 to 1-3/4 inches, so it covers the standard 1-3/4 inch commercial door and the older 1-3/8 inch interior door without a different part number. If your doors run thicker than 1-3/4 inches, up to 2 inches, that's the 4700 (non-LN) version, which is a different lock and comes in satin stainless steel 630 only.
3) Will the Accentra 4722LN latch into the strike that's already in my frame?
The latchbolt is stainless steel with a 1/2 inch throw, so it needs a strike with a matching lip projection and pocket depth. A full ANSI strike, 4-7/8 x 1-1/4 inches with 1-1/4 inch lip to center, ships with the lock, so if your frame is prepped for a standard ANSI strike you're set. An optional T-strike is available to order on the 4700LN for frames prepped that way. The front is a 2-1/4 x 1-1/8 inch beveled front as standard, with flat fronts available to order.
4) Is the Accentra 4722LN lever lock fire rated for a labeled corridor door?
Yes. The 4722LN carries a UL-cUL fire rating up to 3 hours, and it's ANSI/BHMA A156.2 Series 4000 Grade 1. The guardbolt is what makes the latch acceptable on a labeled opening, since it deadlocks the latchbolt with the door closed. It's also 4700LN windstorm certified, though windstorm assemblies are governed by local code, so confirm the full opening against your listing.
5) What cylinder and keying comes with the Accentra 4722LN, and can I get it 7-pin?
A brass 6-pin keyed-random cylinder with two keys is furnished standard. 7-pin is not offered on this lock, so if your facility is standardized on a 7-pin master key system, this is the wrong lock to add to that system. For a 6-pin building, keyed-random means each lock arrives on its own key, so plan on rekeying to your system if you need the corridor doors keyed alike.
6) What is the closest Grade 1 cylindrical lever lock to the Accentra 4722LN if I need a keyed function on a 1-3/8 inch door?
The Accentra 4722LN is a Grade 1 cylindrical corridor lever lock that fits doors from 1-3/8 to 1-3/4 inches. The nearest keyed Grade 1 cylindrical lever with the same door thickness range is the Dexter C1000 Entry/Office, which is Grade 1, keyed, and fits 1-3/8 to 1-3/4 inch doors. The difference is the function: the 4722LN is a corridor lock, while the C1000 Entry/Office is an entry/office function, so the outside lever locks and unlocks differently. Confirm the function on your door schedule before you swap one for the other.
7) The door schedule calls for a classroom lock, not corridor. What Grade 1 cylindrical lever should I order instead of the Accentra 4722LN?
For a classroom opening, the Dexter C1000 Classroom is a Grade 1 keyed cylindrical lever lock with a clutching design that fits doors from 1-3/8 to 1-3/4 inches, the same door range the Accentra 4722LN covers. If the specification calls for classroom security, where both levers are locked from a keyed cylinder on each side, the Dexter C1000 Classroom Security is the Grade 1 version of that function. Corridor and classroom are separate ANSI functions, so the 4722LN is not a substitute for either.
8) I need the same Grade 1 lever but on a 2 inch thick door - what fits?
The Accentra 4722LN adjusts from 1-3/8 to 1-3/4 inches, so a 2 inch door is outside its range. The Corbin Russwin CL3110 is a Grade 1 cylindrical lever lock rated for 1-3/4 to 2 inch doors, and the Falcon K101 is a Grade 1 heavy duty cylindrical lever covering 1-3/8 to 2-1/4 inches. Both are passage function rather than corridor, so they hold Grade 1 and the thicker door but not the keyed corridor operation. For a keyed lock on a 2 inch door, the Corbin Russwin CL33903 electrified lever is Grade 1 at 1-3/4 to 2 inches.
9) What looks like a substitute for the Accentra 4722LN but will not actually work on a keyed corridor opening?
Several Grade 1 cylindrical levers sit next to the Accentra 4722LN on grade but not on function. The Falcon K101 and Falcon T101 are Grade 1 heavy duty cylindrical passage levers, the Corbin Russwin CL3110 is a Grade 1 passage/closet lever, and the BEST 9K 1DT is Grade 1 dummy trim with no latch at all. None of these are keyed, so none of them will do the work of a corridor lock. The 4722LN is keyed with a single cylinder, brass 6-pin, keyed-random with two keys furnished.
10) The opening needs a Schlage C keyway to match our existing keying. Which lever lock should I look at instead?
The Accentra 4722LN ships with a brass 6-pin keyed-random cylinder and two keys, 7-pin not available. If the building keys on Schlage C, the Cal-Royal AG00 entrance lever is a Grade 2 lever with a 6-pin Schlage C keyway keyed different on a 2-3/8 inch backset, and the Cal-Royal AG03 is the classroom function in the same AG series with a 6-pin Schlage C keyway on a 2-3/4 inch backset. The 4722LN uses a 2-3/4 inch standard backset, so the AG03 matches on backset while the AG00 does not.
11) The opening needs access control tied into the card reader. Is there a Grade 1 electrified lever that takes the place of the 4722LN?
The Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever lock running on 12VAC/DC for doors from 1-3/4 to 2 inches. That is the version to look at when the corridor door needs to release from a reader or fire alarm interface rather than a key alone. The Accentra 4722LN is a mechanical corridor lock with no electrified option and fits 1-3/8 to 1-3/4 inch doors, so the electrified swap also changes the door thickness the lock will accept.
12) Do I have to specify handing when I order a 4722LN corridor lever lock?
No handing to specify. The 4722LN is non-handed and reverses in the field, so one part number covers left and right hand openings. That matters if you're buying for a building with mixed swings: you stock one lock, not two, and a lever pulled out of a spare bin will go on any door.
13) Is a Grade 1 lever lock like the Accentra 4722LN worth it over a Grade 2 for an office corridor?
Grade 1 is the heaviest commercial rating and it's what you specify for high-traffic openings: corridors, stairwells, tenant entrances that cycle all day. The 4722LN uses a heavy-gauge steel, die-cast, zinc-plated and chromated mechanism. On a low-traffic interior door, a Grade 2 lock such as the Hager 2525 entry lever or the Falcon B511CP6D entry/office lever does the job for less hardware. The trade is cycle life, not security function.
14) What's a Grade 1 alternative to the Accentra 4722LN if I need a different function on the same doors?
Staying at Grade 1 cylindrical, the Dexter C1000 Series covers entry/office, classroom, classroom security and asylum functions, and the entry/office, classroom and classroom security versions share the 1-3/8 to 1-3/4 inch door range the 4722LN uses. The Corbin Russwin CL3100 Series CL3110 is Grade 1 and fire rated but it's passage, no key, and it's a 1-3/4 to 2 inch door lock. Falcon's K101 is Grade 1 passage across 1-3/8 to 2-1/4 inch doors. None of those are keyed corridor function, so if the corridor function is what you need, the 4722LN is the one.
15) I need a keyless code entry lever instead of a keyed corridor lock. What are my options?
The 4722LN is key-operated only, no keypad. For mechanical code entry on a lever, the Lockey 2835 and 2835DC push-button locks fit 1-3/16 to 2 inch doors, and the Lockey 1150 and 1150S heavy duty keypad levers cover 1-1/8 to 2 inch doors with adjustable backset. On the electronic side there's the Delaney LP250 keypad leverlock. Those door thickness ranges run wider than the 4722LN's, so they're also the answer for a thick door the Accentra won't reach.
16) Do I need to order a strike or trim separately with the Accentra 4722LN, or is it a complete lockset?
It's a complete cylindrical lockset. Levers on both sides in the Augusta design, the latch with guardbolt, the 6-pin brass cylinder with two keys, and the ANSI strike all come in the box. The extras you'd add on the order are the optional flat front in place of the standard beveled front, or the optional T-strike, both available to order for the 4700LN. Everything else you need is the door prep itself.
17) Is there a lighter duty lever lock I can use where Grade 1 is not required?
Where the specification allows Grade 2, the Hager 2525 is a Grade 2 commercial cylindrical entry lever lock covering 1-3/8 to 2 inch doors, and the Hager 2580 is the Grade 2 storeroom function in the same range. Cal-Royal also offers the AG05 Grade 2 storeroom lever with a deadlocking latchbolt for 1-3/8 to 1-3/4 inch doors. The Accentra 4722LN is Grade 1 to ANSI/BHMA A156.2 Series 4000 and UL fire-rated up to 3 hours, so if the opening is fire-rated or the spec names Grade 1, those Grade 2 locks are not equivalents.
18) I need matching passage and dummy levers on the same corridor run as the Accentra 4722LN. What are my options?
For the non-locking openings on the same run, the Falcon K101 is a Grade 1 non-handed cylindrical passage lever, the Design Hardware X75 is a Grade 1 passage lever lockset for 1-3/4 inch doors, and the BEST 9K 1DT is Grade 1 single dummy trim for a leaf that needs a pull only. The Accentra 4722LN itself carries the Augusta lever design and is non-handed, so trim appearance will differ across brands even where the grade matches. If a visual match across the corridor matters more than mixing brands, order the passage and dummy functions in the same series you use for the locked doors.
19) We want keyless entry on some doors instead of a keyed lever. What replaces a corridor lock in that case?
For openings you would rather run on a code than a key, the Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function and ADA compliance for doors from 1-3/16 to 2 inches, and the Lockey 1150 is a heavy duty mechanical keypad lever set for 1-1/8 to 2 inch doors. The Delaney LP250 is a Grade 2 electronic keypad leverlock. These change how the door is controlled: the Accentra 4722LN is a keyed corridor lock with a guardbolt that deadlocks the latchbolt when the door is closed, which the keyless sets do not replicate.
20) For patient rooms and utility closets in a healthcare building, what goes on the doors the corridor lock does not cover?
The Dexter C1000 Asylum is a Grade 1 cylindrical lock in asylum function for 1-3/8 to 2 inch doors, which is the function used where both levers need to stay keyed at all times on a utility or institutional door. For privacy openings, the Arrow MK02-TA is a privacy function cylindrical lock with a fire rating for 1-3/4 to 2 inch doors, though it uses a Tudor knob rather than a lever, which matters where ADA lever operation is required. The Accentra 4722LN covers the corridor doors themselves with Grade 1 and a UL fire rating up to 3 hours.
21) What finishes does the Accentra 4722LN Augusta lever come in for matching the rest of my building?
Eight finishes on the 4700LN: 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 and WSP white suede powder coat. The powder coat options are the ones to look at when you're matching painted door hardware rather than plated. The lever itself is the Augusta design, a return-style lever.
22) Can I use a residential lever set on interior doors in the same building as the Accentra 4722LN?
Behind an apartment or office door, Grade 3 lever sets like the Kwikset 200BRNL Breton passage and the Kwikset 300BRNL Breton privacy cover 1-3/8 to 1-3/4 inch doors, and the Callan Asheville is a Grade 3 passage leverset. Those are built for interior residential openings. The Accentra 4722LN is a commercial Grade 1 corridor lock with a UL fire rating up to 3 hours, so a Grade 3 lever is not an alternative on a rated corridor or stair door.
23) Is a decorative brass lever like the Baldwin 5103 an option for the same doors?
The Baldwin Estate 5103 comes in passage, privacy, and half dummy functions with the 5048 rose, with the half dummy handed left or right. Those are trim-led products for finished interiors and the half dummy versions have to be ordered to the correct hand. The Accentra 4722LN is non-handed with the Augusta lever design and carries Grade 1 with a 2-3/4 inch backset and a 1/2 inch stainless steel latchbolt throw, so the two lines suit different parts of a building rather than substituting for one another.
