Accentra YAL-MO4628LN-626 – Frequently Asked Questions

1) Will the Accentra 4628LN lever lock fit a 1-3/8 inch door, or is it 1-3/4 only?
Both. The 4628LN adjusts from 1-3/8 inch to 1-3/4 inch door thickness, so the same lock covers older 1-3/8 inch interior doors and standard 1-3/4 inch commercial doors. If your doors run thicker than 1-3/4 inch, look at a lock with a wider range instead, such as the Falcon K101 passage lock at 1-3/8 to 2-1/4 inch.
2) What does communicating passage function mean on the Accentra 4628LN, and is it keyed?
Communicating passage means the lever retracts the latch from both sides at all times, with no key and no locking. It is a non-keyed function, so there is no cylinder to key into a master system. Use it on corridor doors, closets, and doors between rooms that need latching but never need to be secured. If you need the door to lock, the 4628LN is the wrong number in the family.
3) Do I need to specify handing when ordering the Accentra 4628LN?
No. The 4628LN is non-handed and installs on a left or right hand door as shipped, and the strike is reversible. The front is universal for both flat and beveled door edges, so you do not have to sort stock by door edge either. That makes it practical for a property manager buying a batch for mixed openings.
4) Can the Accentra 4628LN go on a fire rated door?
Yes. The 4628LN is UL-cUL fire rated up to 3 hours, and it meets ANSI/BHMA A156.2 Series 4000 Grade 2. It is also 4600LN Windstorm certified, though you should confirm against local code for your storm application. The guardbolt deadlocks the latchbolt when the door is closed.
5) Will the Accentra 4628LN latch into the strike already in my frame?
It depends on your existing prep. The 4628LN ships with a 2-3/4 inch backset and a 1/2 inch stainless steel latchbolt throw, with a 1-1/4 inch curved lip strike for a 1-3/4 inch door as standard. If your frame is prepped for a 2-3/8 inch backset, order the lock that way instead, since 2-3/8 is available to order. Other strike lip lengths are a special order, so measure from the frame face to the stop before you commit.
6) What is the closest Grade 2 non-keyed cylindrical lever passage lock to the Accentra 4628LN from another brand?
The Hager 2510 with Withnell lever design is the nearest match. Both are Grade 2 cylindrical passage locks with lever handles; the Hager 2510 is listed for a 1-3/8 inch to 2 inch door thickness range, while the Accentra 4628LN adjusts from 1-3/8 inch to 1-3/4 inch. The Falcon B101 is another Grade 2 cylindrical passage lever lock, described as medium duty and non-handed, matching the 4628LN's non-handed reversibility.
7) I need a passage lever for a high-traffic opening that specs Grade 1 instead of Grade 2. What should I use in place of the Accentra 4628LN?
Step up to a Grade 1 cylindrical passage lever. The Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers, fire rated, and covers 1-3/8 inch to 2-1/4 inch doors. The Corbin Russwin CL3110 is a Grade 1 vandal resistant passage/closet cylindrical lever lock, fire rated, for 1-3/4 inch to 2 inch doors. The Dexter C1000 passage is Grade 1 with clutching non-keyed levers for 1-3/8 inch to 1-3/4 inch doors, the same thickness window the 4628LN covers.
8) My door is 2 inches thick. The Accentra 4628LN tops out at 1-3/4 inch, so what passage lever fits?
For a 2 inch door, the Falcon K101 Grade 1 passage lock covers 1-3/8 inch to 2-1/4 inch, and the Hager 2510 Grade 2 passage lever covers 1-3/8 inch to 2 inch. The Arrow GL01 Grade 2 passage lock with Sierra lever is listed for 1-3/4 inch to 2 inch, and the Corbin Russwin CL3110 Grade 1 passage lever covers 1-3/4 inch to 2 inch. The Accentra 4628LN adjusts from 1-3/8 inch to 1-3/4 inch.
9) The Accentra 4628LN is non-keyed, but I need to lock this door. What keyed lever should I order instead?
The 4628LN is a communicating passage function with no keying, so pick by the locking function you need. For an office or entry door, the Hager 2525 is a Grade 2 cylindrical entry lock with lever handle for 1-3/8 inch to 2 inch doors, and the Falcon B511CP6D is a Grade 2 entry/office cylindrical lever. For a locked storage room, the Hager 2580 is a Grade 2 storeroom cylindrical lock with Withnell lever and the Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors. For a classroom, the Cal-Royal AG03 classroom lever is a Grade 2 with a 6-pin Schlage C keyway and 2-3/4 inch backset, matching the 4628LN standard backset.
10) What looks like a substitute for the Accentra 4628LN but will not actually latch the door?
Dummy trim. The BEST 7KC 1DT is a Grade 2 non-keyed single dummy trim cylindrical lever and the BEST 9K 1DT is the Grade 1 heavy duty single dummy version; both are surface-applied pulls with no latch mechanism. The Callan Bentley BN5051 and the Baldwin Estate 5103 half dummy levers are also dummy function. The Accentra 4628LN is a working communicating passage lock with a 1/2 inch stainless steel latchbolt throw, so dummy trim is not an equivalent on an operating door.
11) I need a passage lever but on a tighter budget for interior residential units. What else is there?
The 4628LN is a commercial Grade 2 cylindrical lock. For interior residential hall and closet doors where commercial cycle life is not the driver, the Kwikset 200BRNL Breton passage lever is a Grade 3 option covering 1-3/8 to 1-3/4 inch doors, and the Callan Asheville is a Grade 3 passage leverset. For a middle ground, the Hager 2510 Withnell passage lever is Grade 2 and spans 1-3/8 to 2 inch doors. None of those should be substituted onto a rated opening unless their own rating covers it.
12) Does the Accentra 4628LN accept an SFIC core if we standardize on interchangeable core?
Not on this number. The 4628LN is the non-keyed communicating passage function, so there is no cylinder in it at all. SFIC in 6 and 7 pin is offered within the 4600LN family on the keyed functions, along with brass 6-pin conventional cylinders keyed random with two keys; 7-pin conventional is not available. Order a keyed function from the series for the doors that need to be in your core system.
13) Is a Grade 3 residential passage lever an acceptable stand-in for the Accentra 4628LN?
Not on a commercial opening. The Kwikset 200BRNL Breton passage lever set is Grade 3 for 1-3/8 inch to 1-3/4 inch doors and the Callan Asheville AH5011 passage leverset is also Grade 3. The Accentra 4628LN is certified to ANSI/BHMA A156.2 Series 4000 Grade 2 and is UL-cUL fire rated up to 3 hours, which is what a commercial or fire-rated door assembly typically requires.
14) I need privacy function for a restroom, not the passage function of the Accentra 4628LN. What are the options?
Switch to a privacy lock. The Hager 2540 is a Grade 2 privacy cylindrical lock with Withnell lever for 1-3/8 inch to 2 inch doors, and the Baldwin Estate 5103 privacy lever with 5048 rose is a privacy function lever. The Kwikset 300BRNL Breton privacy lever set is Grade 3 for 1-3/8 inch to 1-3/4 inch doors. The Accentra 4628LN is a non-keyed communicating passage function and does not provide an inside privacy lock.
15) We want keyless code entry instead of the Accentra 4628LN passage lever. What replaces it?
Mechanical pushbutton lever locks cover that. The Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function and ADA compliance for 1-3/16 inch to 2 inch doors, and the Lockey 2835DC is the double combination version over the same thickness range. The Lockey 1150 heavy duty mechanical keypad lever set with double combination and passage function fits 1-1/8 inch to 2 inch doors. The Accentra 4628LN is a purely mechanical non-keyed passage lock with no code entry.
16) Does the Monroe lever on the Accentra 4628LN have an equivalent trim style from other Grade 2 passage locks?
Each maker names its own lever design, so the trim is the differentiator rather than the function. The Accentra 4628LN carries the Monroe lever design in the 4600 Series. Comparable Grade 2 passage leversets include the Hager 2510 with the Withnell lever, the Arrow GL01 with the Sierra lever, the Design Hardware J75 with a flat lever for 1-3/4 inch doors, and the Bravura Atlanta, Orlando, and Tampa passage leversets, where Tampa uses square trim and Atlanta and Orlando use round trim.
17) We are standardizing a school corridor on one series. Can the Accentra 4628LN passage sit alongside keyed functions in the same family, or do I need a different brand?
Function families are the thing to match. The Accentra 4628LN covers the non-keyed communicating passage opening in the 4600 Series. If you prefer a single family that spans passage plus keyed functions, the Dexter C1000 Series offers a Grade 1 passage with clutching non-keyed levers, a Grade 1 classroom, a Grade 1 classroom security, and a Grade 1 asylum function; the passage, classroom, and classroom security versions are listed for 1-3/8 inch to 1-3/4 inch doors, the same window the 4628LN adjusts through. Cal-Royal's AG Series similarly pairs an entrance, a classroom, and a Grade 2 storeroom function.
18) What finishes does the Accentra 4628LN Monroe lever come in?
Six finish choices: 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 matching existing commercial openings, 626 satin chrome is the usual standard; 613E is the one to pick when you are blending with an aged bronze package.
19) What is the Monroe trim on the Accentra 4628LN, and can I keep the design consistent across a building?
Monroe is the lever design on this 4600 Series cylindrical lock. Because the 4600LN family covers keyed and non-keyed functions, you can run the same Monroe lever look on passage doors with the 4628LN and carry the design through the rest of the series on doors that need locking, which is how you standardize the feel of a floor without mixing lever styles.
20) What is the Accentra 4628LN chassis made of?
The mechanism is heavy-gauge steel, die cast, zinc plated and chromated. That is the corrosion treatment you want on interior commercial doors in schools, healthcare, and multi-tenant residential where the lock gets cycled constantly and cleaned often.
21) Is the Baldwin Estate 5103 passage lever interchangeable with the Accentra 4628LN?
They serve different openings. The Baldwin Estate 5103 passage lever with 5048 rose is a passage function decorative leverset. The Accentra 4628LN is a commercial cylindrical lock certified to ANSI/BHMA A156.2 Series 4000 Grade 2, UL-cUL fire rated up to 3 hours, with a 2-3/4 inch standard backset, guardbolt-equipped locking functions in the series, and fronts universal for flat and beveled door edges. If your drawing calls for a Grade 2 commercial certification or a fire rating, verify those before substituting a decorative lever.
