Accentra YAL-MO4608LN-626 – Frequently Asked Questions

1) What backset does the Accentra 4608LN come with, and can I get 2-3/8 inch?
Standard is a 2-3/4 inch backset, which is the usual commercial bore. A 2-3/8 inch backset is available to order, so if you are replacing hardware on a residential-prep door with the shallower bore you need to specify that at the time of order rather than adjusting it in the field.
2) How does the classroom function on the 4608LN actually work?
Classroom function means the outside lever is locked and unlocked by key only, and the inside lever always retracts the latch for free egress. There is no inside button or thumbturn, so a teacher cannot lock the door from inside the room. If your district wants lockdown from inside the classroom, that calls for a classroom security function instead, like the Dexter C1000 Classroom Security lever.
3) Is the Accentra 4608LN fire rated and does it meet code for a school corridor door?
The 4608LN carries ANSI/BHMA A156.2 Series 4000 Grade 2 certification and is UL-cUL fire rated up to 3 hours, which covers it for labeled openings in educational and commercial buildings. The 4600LN is also Windstorm certified, though you should check your local code for what your specific opening requires.
4) Will the 4608LN latch into the strike that is already in my frame?
The latchbolt has a 1/2 inch stainless steel throw and ships with a 1-1/4 inch curved lip strike sized for a 1-3/4 inch door. That combination drops into a standard ANSI cylindrical frame prep. If your existing frame needs a different lip length to clear the jamb or a wood trim return, other lip lengths are a special order, and all strikes are reversible.
5) Do I need to order the 4608LN handed for a left or right hand door?
No handing to specify. The 4608LN lever lock is non-handed and reversible, and the front is universal for both flat and beveled door edges, so one part number works on either swing. That makes it practical to stock a single lock for a building with mixed door swings.
6) What cylinder and keying comes with the Accentra 4608LN, and can it go on our master key system?
It ships with a brass 6-pin keyed-random conventional cylinder and two keys. Small format interchangeable core is available in 6-pin and 7-pin if you are standardizing on SFIC across a campus, but a 7-pin conventional cylinder is not offered. It is a single-cylinder keyed lock, so all key control is on the outside lever.
7) Will the Accentra 4608LN fit a 2 inch thick door?
No. The 4608LN adjusts from 1-3/8 to 1-3/4 inch door thickness. For a 2 inch door, the Hager 2525 Grade 2 entry lever covers 1-3/8 to 2 inch, and the Falcon K101 Grade 1 passage lever covers 1-3/8 to 2-1/4 inch if the opening does not need a key. Confirm the actual thickness at the lock stile before ordering, since the bored prep is common but the spindle and screw length are what set the range.
8) What is the closest cross-brand equivalent to the Accentra 4608LN classroom lever lock?
The Cal-Royal AG03 is the nearest match in another brand: a Grade 2 classroom lever with a 6-pin Schlage C keyway keyed different and a 2-3/4 inch backset, the same backset the 4608LN uses as standard. Both are keyed cylindrical classroom levers, so the door prep is the same bored 161 preparation. The difference for a locksmith is the cylinder: the 4608LN ships with a brass 6-pin keyed-random cylinder and two keys and also accepts 6 and 7 pin SFIC, while the AG03 is specified in the Schlage C keyway.
9) I need a classroom lever rated for heavier traffic than the Accentra 4608LN. What should I look at?
The Dexter C1000 Series classroom lever is the step up in duty rating. It is a Grade 1 keyed classroom cylindrical lever with a clutching mechanism and fits doors 1-3/8 to 1-3/4 inch, the same thickness range the 4608LN covers. The 4608LN is ANSI/BHMA A156.2 Series 4000 Grade 2 with a 1/2 inch stainless steel latchbolt throw and a guardbolt that deadlocks the latch when the door closes. If the specification calls out Grade 1 on a high-cycle corridor, the C1000 classroom meets that line; if Grade 2 satisfies the spec, the 4608LN does the same job with UL-cUL fire rating up to 3 hours.
10) Our lockdown policy requires keying from inside the classroom. Is the Accentra 4608LN the right function?
No. The 4608LN is a standard classroom function, keyed on the outside only with a single-cylinder keyed configuration. For a lockdown policy that requires a teacher to secure the door from inside the room, the Dexter C1000 Series classroom security lever is the function to specify: it is a Grade 1 classroom security cylindrical lever, clutching and keyed, for doors 1-3/8 to 1-3/4 inch. Classroom security uses cylinders on both sides so the outside lever can be locked without opening the door.
11) For a storeroom or mechanical room instead of a classroom, what takes the place of the Accentra 4608LN?
Use a storeroom function rather than classroom. Two Grade 2 storeroom levers cover it: the Cal-Royal AG05 with a deadlocking latchbolt for doors 1-3/8 to 1-3/4 inch, and the Hager 2580 with the Withnell lever for doors 1-3/8 to 2 inch. Both hold the outside lever locked at all times with key access only, where the 4608LN classroom function lets the key unlock and relock the outside lever for scheduled access.
12) What finishes does the Accentra 4608LN 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 openings in a commercial building, 626 satin chrome is the common spec. The lever design is Monroe, so if adjacent doors use a different Accentra trim design the lever shape will not match even in the same finish.
13) Is a Grade 2 lever lock enough for a high traffic classroom, or should I step up to Grade 1?
Grade 2 to ANSI/BHMA A156.2 is the medium-duty commercial tier and the 4608LN backs it with a heavy-gauge steel, die-cast zinc-plated and chromated mechanism, which holds up in normal classroom and office traffic. For openings that take abuse every period, a Grade 1 classroom lever such as the Dexter C1000 Classroom is the heavier option, and Corbin Russwin's CL3100 Series is Grade 1 and vandal resistant if abuse is the main concern.
14) I need matching locks for storerooms and offices on the same corridor as my classrooms. What pairs with the 4608LN?
The 4608LN is one function within the Accentra 4600 Series, so other functions in the same series with the Monroe trim will match visually and share the same 2-3/4 inch backset prep and adjustable 1-3/8 to 1-3/4 inch thickness. If you are mixing brands instead, Hager's 2500 family covers passage (2510), entry (2525) and storeroom (2580) in Grade 2, and Cal-Royal's AG Series covers entrance (AG00), classroom (AG03) and storeroom (AG05).
15) The door does not need to lock at all. Is there a non-keyed lever that matches the Accentra 4608LN family?
For a corridor or closet door that only needs latching, drop to a passage function. Grade 2 passage levers include the Falcon B101, a non-handed medium duty cylindrical passage lever, and the Hager 2510 passage lever with the Withnell design for doors 1-3/8 to 2 inch. Both are non-keyed, so there is no cylinder to key into the building system. The 4608LN is keyed and non-handed in classroom function, so if half the openings on a floor need keys and half do not, you can run the 4608LN on the keyed doors and a passage lever on the rest.
16) Is a Kwikset 200BRNL Breton lever an acceptable substitute for the Accentra 4608LN on a school door?
It is not equivalent. The Kwikset 200BRNL Breton is a Grade 3 passage lever for doors 1-3/8 to 1-3/4 inch, non-keyed, so it neither locks nor meets a commercial grade line. The 4608LN is a Grade 2 keyed classroom lever certified to ANSI/BHMA A156.2 Series 4000 with UL-cUL fire rating up to 3 hours. Where a Grade 3 lever is acceptable and the door only needs to latch, the Breton works; on a rated classroom opening it does not.
17) We want keyless entry on the classroom doors instead of the Accentra 4608LN. What are the options?
For mechanical pushbutton in place of a key, the Lockey 2835 keyless lever lock has passage function and is ADA compliant for doors 1 3/16 to 2 inch, with a double combination version, the 2835DC, over the same thickness range. The Delaney LP250 is a Grade 2 electronic keypad leverlock if you want a battery-powered credential instead. The trade-off against the 4608LN is keying: the Accentra takes a brass 6-pin cylinder or 6 and 7 pin SFIC, so it can be brought into an existing master key system that a keypad cannot join.
18) How does the Accentra 4608LN compare to an entrance or office function lever for an administrative door?
An office door usually wants an entrance/office function so staff can lock the lever with a pushbutton or turn and still exit freely. The Falcon B511CP6D is a Grade 2 medium duty entry/office cylindrical lever, and the Cal-Royal AG00 is a Grade 2 entrance lever with a 6-pin Schlage C keyway keyed different, 2-3/8 inch backset, for doors 1-3/8 to 1-3/4 inch. The 4608LN classroom function has no inside locking control at all, which is exactly why schools spec it for instruction rooms and something else for the office.
19) Is there a Grade 1 vandal resistant alternative if the Accentra 4608LN lever gets abused on a corridor door?
For abuse-prone openings, the Corbin Russwin CL3110 is a Grade 1 vandal resistant cylindrical lever in passage/closet function, fire rated, for doors 1-3/4 to 2 inch, and the Falcon T101 is a Grade 1 heavy duty passage lever with pressure release technology that lets the lever give under downward force. Both are non-keyed, so they suit a door that does not need to lock. The 4608LN is the Grade 2 keyed classroom option and fits 1-3/8 to 1-3/4 inch doors, a thinner range than the CL3110.
20) For a behavioral health or detention room, is the Accentra 4608LN classroom function correct?
No. Those rooms normally take an asylum function, which is keyed on both sides so the door cannot be locked or unlocked without a key from either direction. The Dexter C1000 asylum (F87) is a Grade 1 option for doors 1-3/8 to 2 inch, and the Arrow MK33-BD-CS is a Grade 2 heavy duty asylum lock with a ball knob and a conventional cylinder in the Schlage C keyway. The 4608LN classroom function keys the outside only and leaves the inside lever always free.
21) What does the guardbolt on the 4608LN do?
The guardbolt deadlocks the latchbolt whenever the door is closed, which stops the latch being shimmed or carded from the outside. It is standard on all locking functions in the 4600 Series, so you do not order it separately.
22) What should I pair with the Accentra 4608LN on a door that only needs an inactive lever?
For an inactive leaf or pull-side trim, use a dummy. The BEST 7KC Series 1DT single dummy trim is a Grade 2 medium duty non-keyed cylindrical lever dummy, and the BEST 9K Series 1DT is the Grade 1 heavy duty version of the same single dummy trim. Either gives you a lever with no latch on the door, while the 4608LN carries the keyed classroom function and the 1/2 inch stainless latchbolt on the active leaf.
23) Can I match the Accentra 4608LN with a knob instead of a lever somewhere in the same building?
Knob versions exist in other lines but not in the same trim family. The Arrow RL Series HK11 is a turn-pushbutton entrance cylindrical lock with a ball knob and conventional cylinder for doors 1-3/8 to 1-3/4 inch, the same door range as the 4608LN. Keep in mind that lever trim is generally what ADA-governed openings call for, and the 4608LN uses the Monroe lever design across all six of its finishes.
