Accentra YAL-MO4605LN-626 – Frequently Asked Questions

1) What does storeroom function mean on the Accentra 4605LN lever lock, and is it right for a supply closet?
Storeroom function means the outside lever is always locked. Entry is by key only, and the inside lever always retracts the latch for free egress. There is no button or turn to leave it unlocked, which is what you want on a supply room, electrical closet, or mechanical room that should never be left open by accident. The 4605LN uses a single cylinder, keyed outside only.
2) Will the Accentra 4605LN fit a 1-3/8 inch door as well as a standard 1-3/4 inch commercial door?
Yes. The 4605LN adjusts for door thickness from 1-3/8 to 1-3/4 inches, so the same lock covers older 1-3/8 inch interior doors and standard 1-3/4 inch commercial doors. Note the supplied strike is a 1-1/4 inch curved lip sized for a 1-3/4 inch door; other lip lengths are a special order, and all strikes are reversible.
3) What backset does the Accentra 4605LN storeroom lever come with, and can I get 2-3/8 inch?
It ships 2-3/4 inch backset as standard, which is the usual commercial bore. A 2-3/8 inch backset is available to order, so specify it up front if you are working into residential-style prep or an existing 2-3/8 inch bore.
4) Can the Accentra 4605LN go on a fire rated door?
Yes. The 4605LN carries UL-cUL fire ratings up to 3 hours and is ANSI/BHMA A156.2 Series 4000 Grade 2. The guardbolt deadlocks the latchbolt when the door is closed, which is standard on all locking functions in the 4600 Series and is part of what makes it suitable for rated openings.
5) Will the 1/2 inch latchbolt on the 4605LN work with the strike already in my frame?
The latchbolt is a 1/2 inch throw stainless steel unit, which is the standard cylindrical latch projection, so it will normally engage an existing cylindrical strike prep in the frame. The front is universal for both flat and beveled door edges, so you do not need to order a separate front for a beveled edge. If your frame strike lip is not 1-1/4 inch, other lip lengths are a special order.
6) Can I key the Accentra 4605LN into an existing small format interchangeable core system?
Yes. The 4605LN accepts 6 and 7 pin SFIC, so it can be brought into an existing interchangeable core keying system. As supplied conventionally it comes with a brass 6-pin keyed-random cylinder and two keys. A 7-pin conventional cylinder is not offered.
7) My doors are 2 inches thick. Will the Accentra 4605LN work?
No. The 4605LN tops out at 1-3/4 inches. For a 2 inch door, look at the Hager 2510 or 2525 Grade 2 cylindrical levers, both rated 1-3/8 to 2 inches, or the Falcon K101 Grade 1 which covers 1-3/8 to 2-1/4 inches. Match the function you need, since those particular models are passage and entrance rather than storeroom.
8) What is a direct cross for the Accentra 4605LN storeroom lever lock from another brand?
The Hager 2580 with Withnell lever is the closest straight equivalent: it is a Grade 2 storeroom cylindrical lock, the same function and grade as the Accentra 4605LN with Monroe trim. The Hager 2580 covers doors 1-3/8 inch to 2 inch, while the 4605LN is adjustable from 1-3/8 inch to 1-3/4 inch, so the Hager reaches thicker doors. Cal-Royal AG05 is a second Grade 2 storeroom lever with a deadlocking latchbolt on a 1-3/8 inch to 1-3/4 inch door range, matching the Accentra range exactly.
9) I need a storeroom-function lever for a 2 inch thick door - what should I order instead of the 4605LN?
The Accentra 4605LN adjusts from 1-3/8 inch to 1-3/4 inch doors, so a 2 inch door is outside its range. The Hager 2580 Grade 2 storeroom lock with Withnell lever is listed for 1-3/8 inch to 2 inch doors and keeps the same storeroom function and Grade 2 rating. For a heavier Grade 1 option on thick doors, the Dexter C1000 Asylum lock covers 1-3/8 inch to 2 inch, though asylum function keys both sides rather than storeroom.
10) Is an entrance or office function lever the same thing as the 4605LN storeroom lock?
No. The Accentra 4605LN is storeroom function, which means the outside lever is always locked and requires a key every time, with the latch retracting freely from inside. An entrance or office lock such as the Falcon B511CP6D Grade 2 entry/office lever, the Hager 2525 Grade 2 entry lock, or the Cal-Royal AG00 Grade 2 entrance lever lets the outside lever be left unlocked, which is the opposite of what a storeroom opening is specified for. Pick entrance or office where staff need to leave the door open during business hours; pick storeroom where it must never be left unsecured.
11) For a school corridor, should I use the Accentra 4605LN or a classroom function lever?
The Accentra 4605LN is storeroom function - the outside lever stays locked at all times and is keyed from the corridor side, which suits storage, mechanical, and IT rooms. A classroom opening usually calls for classroom function, where a key unlocks and relocks the outside lever: the Cal-Royal AG03 classroom lever with a 6-pin Schlage C keyway on a 2-3/4 inch backset, or the Dexter C1000 classroom security lock, Grade 1 for 1-3/8 inch to 1-3/4 inch doors, cover that. The 4605LN also uses a 2-3/4 inch standard backset, so backset prep is common between it and the AG03.
12) Do I have to specify handing when ordering the 4605LN Monroe lever?
No. The 4605LN is non-handed and fully reversible, and the strike is reversible too. One part number covers left and right hand openings, which makes it easier to stock a single SKU across a building.
13) Is Grade 2 enough for a school or hospital corridor, or should I step up to Grade 1?
Grade 2 covers moderate to heavy commercial traffic and the 4605LN is listed for offices, schools, healthcare, retail, industrial, multi-tenant residential, and government work. For very high cycle openings or vandal exposure, a Grade 1 cylindrical is the step up: the Corbin Russwin CL3100 Series is a Grade 1 vandal resistant cylindrical lever, and the Dexter C1000 Series and Falcon T101 are Grade 1 heavy duty cylindrical levers.
14) The door does not need to lock - what is the non-keyed version to order in place of the 4605LN?
The Accentra 4605LN is a keyed single-cylinder storeroom lock. For an unlocked opening, the Falcon B101 is a Grade 2 medium duty cylindrical passage lever with a non-handed design, and the Hager 2510 is a Grade 2 passage lever for 1-3/8 inch to 2 inch doors. Design Hardware J75 is another Grade 2 passage lever, listed for 1-3/4 inch doors only. Passage locks have no cylinder, so they will not accept your keyway or join a master key system.
15) Can I use a Grade 3 residential lever instead of the Accentra 4605LN on a commercial storeroom?
The Accentra 4605LN is a commercial Grade 2 lock. Grade 3 levers such as the Cal-Royal AUS00 entrance/office lock, the Master Lock BC Series keyed entry lever, or the Kwikset 200BRNL Breton passage lever sit a grade below and are not storeroom function. If your spec or facility standard calls for a keyed storeroom opening at commercial grade, stay with the 4605LN or a Grade 2 storeroom peer such as the Cal-Royal AG05.
16) I want keyless entry on a storeroom door - what replaces the 4605LN?
The Accentra 4605LN uses a brass 6-pin keyed cylinder with two keys furnished. To drop keys entirely, the Delaney LP250 is a Grade 2 electronic keypad leverlock, and the Lockey 1150 is a heavy duty mechanical keypad lever set for 1-1/8 inch to 2 inch doors with a double combination. Note the Lockey 1150 and the Lockey 2835 keypad levers are passage function, so they release the latch on code rather than holding a storeroom lockout.
17) Does the 4605LN work for an access control tie-in, or do I need an electrified lever?
The Accentra 4605LN is a mechanical cylindrical lock with a keyed cylinder and no electrical provision. For a card reader or access control tie-in on a cylindrical opening, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified lever at 12VAC/DC with an NZ lever and D rose, listed for 1-3/4 inch to 2 inch doors. Choose the electrified lever where the door must unlock from a system; keep the 4605LN where key control alone governs the room.
18) Is there a vandal resistant alternative to the Accentra 4605LN for an abuse-prone opening?
For openings that take abuse, the Corbin Russwin CL3110 is a Grade 1 vandal resistant cylindrical lever lock, fire rated, for 1-3/4 inch to 2 inch doors. It is passage/closet function, so it does not lock and cannot replace the keyed storeroom duty of the Accentra 4605LN - use it only where the door needs latching but no key control, and stay with the 4605LN or a Grade 2 storeroom peer where the room must be secured.
19) What is the difference between the Accentra 4605LN and an asylum or utility function lever?
The 4605LN is storeroom function: keyed outside, always locked outside, free egress from inside. Asylum or institution function, such as the Dexter C1000 Asylum F87 Grade 1 lock for 1-3/8 inch to 2 inch doors or the Arrow MK33 Grade 2 asylum lock with a Schlage C keyway, requires a key on both sides, so there is no free egress. Asylum function is specified for utility and secure holding rooms; it is not a substitute on any door that needs to be exited without a key.
20) What finishes does the Accentra 4605LN Monroe lever come in for matching the rest of my building?
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. 626 satin chrome is the usual commercial default, so that is the one to match if the other openings were specified generically.
21) Is the Accentra 4605LN rated for windstorm openings?
The 4600LN is windstorm certified. Local code governs the assembly as a whole, so verify the door, frame, and hardware combination against the requirement for your jurisdiction before specifying it on a storm rated opening.
22) If I need a non-keyed lever to match the Monroe design on other doors, what do I order?
The 4605LN itself is keyed storeroom only, so a passage or dummy opening needs a different function from the 4600 Series line rather than this model. If you are not tied to Accentra trim, we carry non-keyed cylindrical levers such as the Falcon B101 Grade 2 passage and the BEST 7KC Series single dummy trim, both Grade 2.
23) What do I order to match the 4605LN lever on a door that does not get a working latch?
For a dummy trim that matches the look of a keyed cylindrical lever without any latch, the BEST 7KC Series 1DT single dummy trim is a Grade 2 non-keyed cylindrical lever, and the BEST 9K Series 1DT is the Grade 1 heavy duty equivalent. Callan Bentley is another Grade 2 dummy lever. These mount surface trim only and will not secure the opening the way the storeroom-function 4605LN does.
24) I am standardizing a building on one lever look - can I mix the 4605LN with decorative levers?
The Accentra 4605LN uses the Monroe lever trim and comes in bright brass 605, satin brass 606, dark oxidized satin bronze 613E, bright chrome 625, satin chrome 626, and black suede powder coat. Decorative lines such as the Baldwin Estate 5103 with 5048 rose or the Emtek Classic and Arts and Crafts leversets carry their own lever shapes and rose profiles, so they will read as a different family next to Monroe trim. To keep one look across function types in a commercial building, pair the 4605LN with other 4600 Series functions rather than a decorative residential line.
25) What is the 4605LN lock body made of?
The mechanism is heavy-gauge steel, die-cast, zinc-plated and chromated, with a stainless steel latchbolt. That plating package is what resists corrosion in interior commercial service.
