Accentra YAL-AU4628LN-626 – Frequently Asked Questions

1) Will the Accentra 4628LN lever lock fit a 1-3/8 inch door, or only 1-3/4?
Both. The 4628LN is adjustable from 1-3/8 to 1-3/4 inches, so the same lock covers the older 1-3/8 inch interior doors and standard 1-3/4 inch commercial doors without a different part number. Worth knowing if you're working a building with mixed door stock: one SKU spans both. Anything thicker than 1-3/4 is outside the range.
2) What does the communicating passage function on the 4628LN actually do, and where would I use it?
It's a non-keyed lock: both levers always retract the latch, and there is no cylinder, no key, no thumbturn. Nobody gets locked out and nobody gets locked in. That's what you want on a connecting door between two rooms, a corridor door, a closet, or anywhere you need a latched door that always opens from both sides. If you need the door to lock, this isn't the one, pick a keyed or privacy function instead.
3) Does the 4628LN come with a 2-3/4 inch backset, and can I get 2-3/8 for a residential-prep door?
2-3/4 inches is the standard backset shipped. 2-3/8 is available but only as an ordered option, not off the shelf, so it has to be specified. Check the existing cross-bore center distance from the door edge before you order: those are the two backsets you'll find in the field, and the wrong one won't line up with the prep you already have.
4) Will the Accentra 4628LN latch into the strike that's already in my frame?
The latchbolt throw is 1/2 inch stainless steel, which is the normal cylindrical-lock throw, so it will engage a standard cylindrical strike pocket. The strike supplied is a 1-1/4 inch curved lip sized for a 1-3/4 inch door, and it's reversible. If your frame has a deeper or shallower reveal, other lip lengths are available on special order. Note there's no guardbolt on this one, the deadlocking guardbolt is standard only on the locking functions, and passage isn't one of them.
5) Is the 4628LN handed? I don't know the swing of the door yet.
No handing to specify. The 4628LN is non-handed and the front is universal, machined to sit on both flat and beveled door edges, and the strike is reversible. You can order it before the door swing is settled and it'll work left or right hand, in or out. That's the reason it's an easy lock to stock across a property.
6) Can I use a passage lever lock on a fire-rated door?
Yes on the 4628LN specifically: the 4600LN locks are UL-cUL fire rated up to 3 hours. The lock itself won't hold up your door's rating. What you do need is a positive-latching device, which this is, and no hold-open. It also carries a 4600LN windstorm certification, though you should read that against your local code before you rely on it for an opening in a windborne-debris zone.
7) I need a bathroom or bedroom door to lock from the inside. Is the 4628LN the right lock for that?
It isn't. Communicating passage is non-keyed and has no locking mechanism at all, so there's no privacy pushbutton or turn. For a bed or bath door you want a privacy function: the Hager 2540 Grade 2 with the Withnell lever, or the Arrow MK02-TA Grade 2 privacy if a knob works for the opening. Order the passage version only for doors that should never lock.
8) Is a dummy trim lever the same as the 4628LN communicating passage lock?
No, and they are not interchangeable. The Accentra 4628LN is a working cylindrical lock with a 1/2 inch stainless steel latchbolt, a guardbolt, and a strike - the lever retracts the latch and the door latches shut. A dummy trim such as the BEST 7KC 1DT single dummy trim, Grade 2 non-keyed, or the Grade 1 heavy duty BEST 9K 1DT, is a fixed pull with no latch and no bored latch prep at all. Dummy trim belongs on an inactive leaf or a door held by a ball catch. If the door has a 2-3/4 inch backset bore and a strike in the frame, it needs a latching lock like the 4628LN, not dummy trim.
9) What is a Grade 2 passage lever equivalent to the Accentra 4628LN from another brand?
The Hager 2510 is the closest straight equivalent: a Grade 2 cylindrical passage lever lock with the Withnell lever design, covering doors 1-3/8 inch to 2 inch thick. The Accentra 4628LN is a Grade 2 non-keyed communicating passage cylindrical lever with the Augusta lever, adjustable from 1-3/8 inch to 1-3/4 inch. The Falcon B101 is another Grade 2 medium duty cylindrical passage lever with a non-handed design, matching the 4628LN's non-handed reversibility. Any of the three drops into the same 2-3/4 inch backset commercial door prep where the opening calls for a free-turning lever on both sides with no locking.
10) Does the Accentra 4628LN work on a 2 inch thick door, and what should I order if not?
The Accentra 4628LN adjusts from 1-3/8 inch to 1-3/4 inch, so a 2 inch door is past its range. For a Grade 2 passage lever that reaches 2 inches, the Hager 2510 with the Withnell design covers 1-3/8 inch to 2 inch. In Grade 1, the Falcon K101 passage goes to 2-1/4 inch and the Corbin Russwin CL3110 passage covers 1-3/4 inch to 2 inch. The Arrow GL01 Grade 2 passage also runs 1-3/4 inch to 2 inch. Measure the leaf at the lock edge before ordering, since fire-rated and exterior-grade leaves are often thicker than the interior doors on the same floor.
11) I need a heavy duty passage lever for a high traffic corridor - what should I use instead of the 4628LN?
Step up to Grade 1 for corridor traffic. The Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers, fire rated, and it takes a wider door range of 1-3/8 inch to 2-1/4 inch. The Falcon T101 is also Grade 1 heavy duty passage with pressure release technology. The Corbin Russwin CL3110 is a Grade 1 vandal resistant passage lever, fire rated, for doors 1-3/4 inch to 2 inch. The Accentra 4628LN is Grade 2 and adjusts from 1-3/8 inch to 1-3/4 inch, which suits offices, classrooms and tenant doors rather than a main circulation route being hit all day.
12) The door needs to lock - what is the keyed version to order instead of the 4628LN?
The Accentra 4628LN is non-keyed, so the lever turns freely from both sides and there is no cylinder. For a door that has to secure, the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever for doors 1-3/8 inch to 2 inch, and the Hager 2525 is a Grade 2 commercial entry lock with a lever over the same door range. The Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt, 1-3/8 inch to 1-3/4 inch. The Falcon B511CP6D covers entry/office in Grade 2 medium duty. Storeroom keeps the outside lever locked at all times; entry/office lets staff leave it unlocked during business hours.
13) Can I use the Arrow GL01 passage lock in place of the Accentra 4628LN?
Check the door thickness before committing. The Arrow GL01 is a Grade 2 passage function cylindrical lock with the Sierra lever, non-keyed, but it is built for doors 1-3/4 inch to 2 inch. The Accentra 4628LN adjusts from 1-3/8 inch to 1-3/4 inch. The two only overlap at a 1-3/4 inch door. On a 1-3/8 inch door, which is common on interior wood doors in older multi-family stock, the GL01 does not apply and the 4628LN does. On a 2 inch door the reverse is true.
14) The restroom door needs privacy, not passage - what replaces the 4628LN there?
A communicating passage lock like the Accentra 4628LN has no locking function at all, so it will not serve a restroom or bedroom door. For privacy, the Hager 2540 with the Withnell lever is a Grade 2 privacy cylindrical lock for doors 1-3/8 inch to 2 inch. The Kwikset 300BRNL Breton privacy leverset is a Grade 3 option for 1-3/8 inch to 1-3/4 inch doors. The Baldwin Estate 5103 privacy lever with the 5048 rose covers the same function in a decorative line. Keeping the same lever family across a floor is easier if the passage doors take the 4628LN and the privacy doors take a matching trim from the same series.
15) Is Grade 2 enough for a commercial corridor, or should I be buying Grade 1?
Grade 2 under ANSI/BHMA A156.2 Series 4000 is the middle commercial tier, and for a passage door with no cylinder and moderate traffic it's the normal spec, the mechanism is heavy-gauge steel, die-cast, zinc-plated and chromated. Where you'd step up to Grade 1 is a high-abuse opening: a school corridor, a stairwell, a public restroom. In that case look at the Falcon K101, a Grade 1 heavy-duty passage cylindrical lock that spans 1-3/8 to 2-1/4 inch doors and is fire rated, or the Corbin Russwin CL3110, a Grade 1 vandal-resistant passage lever for 1-3/4 to 2 inch doors.
16) What finishes does the Accentra 4628LN Augusta lever come in, and which one matches existing satin chrome hardware?
Six finishes: 605 bright brass, 606 satin brass, 613E dark oxidized satin bronze equivalent, 625 bright chrome, 626 satin chrome, and BSP black suede powder coat. For a building already on satin chrome hardware, 626 is the match, it's the most common commercial finish you'll find on existing lever sets. The 613E is an equivalent to dark oxidized satin bronze rather than the true 613 living finish, so it won't patina the same way if you're blending it with older bronze.
17) I need matching levers throughout a building but some doors have to lock. Can I keep the Augusta lever look across all of them?
Yes. The Augusta lever trim on the 4628LN is one trim design within the Accentra 4600LN cylindrical family, and the family carries keyed functions alongside this non-keyed passage. That means the office doors, storerooms and classrooms can take the locking functions in the same Augusta lever and same finish, so the whole floor reads as one hardware package. On the keyed siblings, cylinders are brass 6-pin keyed-random with two keys furnished; 6 and 7 pin SFIC is offered, but 7-pin conventional is not.
18) Is the Accentra 4628LN the same thing as a Yale 4628LN?
Same lock. Yale Commercial's 4600LN cylindrical line was rebranded to Accentra under ASSA ABLOY, so a 4628LN specified on an older drawing as Yale is filled by the Accentra 4628LN, model YAL-4628LN. Function, Augusta trim, 2-3/4 inch backset and the 1-3/8 to 1-3/4 inch thickness range are unchanged. If a spec sheet in your file says Yale 4628LN, you're ordering the right part.
19) For a patient room or holding room, is the 4628LN the right lock?
No. Those openings call for an asylum or institutional function, where both levers lock and a key retracts the latch from either side. The Dexter C1000 is a Grade 1 asylum function (F87) cylindrical lock for doors 1-3/8 inch to 2 inch. The Arrow MK33-BD-CS is an asylum/institution/utility cylindrical lock, heavy duty, with a ball knob and a conventional cylinder in the Schlage C keyway. The Accentra 4628LN is a non-keyed Grade 2 communicating passage lock, so the levers always turn and no key is involved - it belongs on the corridor and office doors of the same facility, not the secured rooms.
20) What is the difference between the Accentra 4628LN and a classroom lever like the Dexter C1000 or Cal-Royal AG03?
Function and keying. The Dexter C1000 classroom is a Grade 1 keyed clutching cylindrical lever lock for doors 1-3/8 inch to 1-3/4 inch, and there is a matching Grade 1 classroom security version over the same door range. The Cal-Royal AG03 classroom lever is a Grade 2 with a 6-pin Schlage C keyway keyed different and a 2-3/4 inch backset. All of those lock the outside lever by key so a teacher can secure the room. The Accentra 4628LN is non-keyed with no cylinder - the same 2-3/4 inch standard backset and 1-3/8 inch to 1-3/4 inch door adjustment, but the lever never locks. Use it on the classroom's closet or vestibule door and a classroom function on the entry.
21) Can I put a keypad lever on the door instead of the 4628LN if I want no keys but controlled access?
Yes, and the mechanical keypad sets are the usual route. The Lockey 1150 is a heavy duty mechanical keypad lever set with double combination in a passage function, for doors 1-1/8 inch to 2 inch, and the 1150S adds an adjustable backset over the same door range. The Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function and ADA compliance for doors 1-3/16 inch to 2 inch, with a double combination 2835DC. The Delaney LP250 is a Grade 2 electronic keypad leverlock. The Accentra 4628LN is a straight non-keyed passage lock with no code entry - it gives free movement, not controlled access.
22) Is the Design Hardware J75 passage lever a drop-in for the Accentra 4628LN?
Only on a 1-3/4 inch door. The Design Hardware J75 is a Grade 2 passage lever lockset with a flat lever, specified for 1-3/4 inch doors, and the X75 is the Grade 1 version of the same flat-lever passage set, also 1-3/4 inch. The Accentra 4628LN adjusts across 1-3/8 inch to 1-3/4 inch, so it covers the thinner interior doors the J75 and X75 do not. Lever shape differs as well - the J75 and X75 use a flat lever, the 4628LN uses the Augusta design.
23) Will a lever trim for an exit device work in place of the 4628LN?
No. The Corbin Russwin 585F715 is a Grade 1 lock lever for the ED8000 pushpad exit device and the CL3300 cylindrical lock series, and the Imperial USA ED-EL500HD is heavy duty escutcheon lever trim with an entry function for the ED-500 series. Both are trim that mounts to an exit device or its series chassis - they are not a standalone lock and there is no lock case behind them. The Accentra 4628LN is a complete cylindrical lever lock with its own chassis, 1/2 inch stainless steel latchbolt and reversible strike, installed in a standard bored door prep.
24) The door needs an electrified lever that unlocks on fire alarm - what replaces the 4628LN?
The Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever with an NZ lever and D rose, running 12VAC/DC, for doors 1-3/4 inch to 2 inch, and there is a keyed 12VAC/DC version of the same fail safe lever over the same door range. Fail safe means the lever unlocks when power drops, which is what an access control or alarm-release opening requires. The Accentra 4628LN is a mechanical non-keyed communicating passage lock with no electrical provision - it is already always free, so it cannot be tied into a release scheme.
25) Does the Accentra 4628LN need any extra hardware, or is it complete out of the box?
It ships as a complete passage set: both levers, the latch with the 1/2 inch stainless throw, and a 1-1/4 inch curved lip strike. No cylinder, because there is no keyway on the passage function, so there's nothing to order from a keying schedule. The only things you'd add separately are a non-standard strike lip length or the 2-3/8 inch backset, and both of those are order-time specifications, not accessories you buy after.
