Accentra AU-5422LN-626 – Frequently Asked Questions

1) Will the Accentra 5422LN lever lock fit a 2-inch thick door?
Yes. The 5422LN cylindrical lever lock adjusts from 1-3/4 inches to 2-1/4 inches of door thickness, so 2 inches is inside its range with no special order. That upper end is wider than most cylindrical locks reach, which matters on thick institutional doors and on doors that have been faced or armored. What it does not do is go thinner: at 1-3/8 inches, the common older interior thickness, this is the wrong lock. For a 1-3/8 inch door look at a Grade 1 lock rated down that far, such as the Falcon K101, which covers 1-3/8 to 2-1/4 inches.
2) What does the corridor function on the Accentra 5422LN actually do at the door?
Corridor function is the classroom-corridor style lock used on stairwell and corridor openings: it is keyed on the outside, and the lever always retracts the latch from the inside for free egress. The 5422LN is a keyed corridor lock with a guardbolt that deadlocks the latchbolt when the door closes, so the latch cannot be carded back. If you actually want an office door that a user can lock and unlock by pushbutton from inside, corridor is the wrong function and you want an entry/office lock instead.
3) Can I put a 5422LN lever lock on a fire-rated door?
Yes. The 5422LN is UL/cUL fire rated up to 3 hours and is certified to ANSI/BHMA A156.2 Series 4000 Grade 1, so it carries on a 3-hour rated opening. It is also windstorm certified, subject to your local code. The guardbolt is standard on the locking functions, which is what a fire-door inspector expects to see holding the latch positively engaged.
4) Will the Accentra 5422LN drop into my existing 2-3/4 inch backset prep?
Standard backset on the 5422LN is 2-3/4 inches, the usual commercial bored-door backset, so a door already prepped for a commercial cylindrical lock takes it directly. For deeper stiles, 3-3/4 inch and 5 inch extension links are available to order. The lock is non-handed, so you do not specify left or right, and the strike is reversible: a 1-1/4 inch curved lip for a 1-3/4 inch door comes standard, with other lip lengths orderable if your frame reveal needs them.
5) I need a Grade 1 corridor or classroom lever lock but the 5422LN does not fit my door. What else is there?
On a 1-3/8 inch door the 5422LN is out, since it starts at 1-3/4 inches. The Dexter C1000 Series classroom lever is Grade 1 and covers 1-3/8 to 1-3/4 inches, and the C1000 classroom security version covers the same range if you want key control on both sides. For a thicker door in the 1-3/4 to 2 inch band with vandal resistance, the Corbin Russwin CL3100 Series is Grade 1 and fire rated. If the opening needs no key at all, the Falcon K101 is a Grade 1 fire-rated passage lock spanning 1-3/8 to 2-1/4 inches.
6) What is the closest Grade 1 cylindrical lever lock to the Accentra 5422LN if the Augusta trim is not wanted?
The Accentra 5422LN is a Grade 1 cylindrical lever lock with the Augusta lever trim. For a Grade 1 cylindrical lever in a different trim family, the Falcon K101 is a Grade 1 heavy duty cylindrical lock listed for 1-3/8 inch to 2 inch door thickness with a fire rating, and the Corbin Russwin CL3110 is a Grade 1 vandal resistant cylindrical lever lock listed for 1-3/4 inch to 2 inch doors with a fire rating. Both are non-keyed passage function, so they suit an opening that does not need a key; the 5422LN covers the corridor function with a keyed cylinder.
7) Can a Grade 2 lever lock be used in place of the Accentra 5422LN on a lighter traffic door?
Yes, where the specification allows Grade 2. The Accentra 5422LN is Grade 1. Grade 2 cylindrical lever options include the Hager 2580 storeroom lever for 1-3/8 inch to 2 inch doors, the Hager 2525 entry lever for the same thickness range, and the Falcon B511CP6D medium duty entry/office lever. The 5422LN carries a corridor function and adjusts from 1-3/4 inch to 2-1/4 inch, so it covers thicker doors than the Hager pair and answers a spec that calls out Grade 1.
8) What Grade 1 lever should be used instead of a corridor lock on a classroom or a secure storage door?
The Accentra 5422LN is a corridor function lock. Where the opening needs a different function at the same grade, the Dexter C1000 Series offers Grade 1 classroom, Grade 1 classroom security, and Grade 1 entry/office clutching keyed levers for 1-3/8 inch to 1-3/4 inch doors, plus a Grade 1 asylum function lock for 1-3/8 inch to 2 inch doors. Match the function to the door before matching the trim.
9) What is the difference between the Accentra 5422LN and a residential Grade 3 lever set that looks similar?
Grade level and door range. The Accentra 5422LN is a Grade 1 commercial cylindrical lock rated ANSI/BHMA A156.2 Series 4000 with a UL/cUL fire rating up to 3 hours and a 1/2 inch stainless steel latchbolt throw. The Kwikset 200BRNL Breton passage lever is Grade 3 for 1-3/8 inch to 1-3/4 inch doors, the Master Lock RL Series keyed entry lever is Grade 3, and the Cal-Royal AUS00 entrance/office lever is Grade 3 for 1-3/8 inch to 1-3/4 inch doors. A specification calling for Grade 1 or a fire-rated opening is answered by the 5422LN.
10) Is there an electrified lever lock alternative when the corridor door needs to release on a fire alarm?
The Accentra 5422LN is a mechanical Grade 1 cylindrical lever lock with no electrical option. For an access controlled opening, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever lock at 12VAC/DC for 1-3/4 inch to 2 inch doors, offered with the NZ lever and D rose and in a keyed version. Fail safe unlocks when power drops, which is what a life safety release requires.
11) Is the 1/2 inch latchbolt throw on the 5422LN enough, or do I need the 3/4 inch?
Standard throw is 1/2 inch stainless steel, which latches into a normal hollow metal frame strike with a typical gap. Order the 3/4 inch throw when the gap between door and frame is oversized, the door has sagged, or a wood frame has moved, because a 1/2 inch bolt loses engagement fast once the reveal grows. Both throws are stainless steel, and the guardbolt deadlocks whichever one you use.
12) What cylinder and keying comes with the 5422LN, and can I key it into my building master system?
Each 5422LN ships with a brass 6-pin keyed-random cylinder and two keys. A 7-pin cylinder is available to order, along with other cylinder and keying options, so the lock can be brought into an existing masterkeyed system rather than left keyed random. Specify the keying at the time of order; keyed-random is what you get if you do not.
13) Is a Grade 1 cylindrical lever like the 5422LN overkill for my building, or should I use a Grade 2?
Grade 1 is the commercial heavy-traffic tier and is what you want on corridors, stairwells, schools, and healthcare openings where the lever is worked hundreds of times a day. The 5422LN is Grade 1 with a heavy-gauge steel, zinc-plated and dichromated mechanism. For lower-traffic interior doors in the same building, a Grade 2 lever such as the Hager 2580 storeroom or the Falcon B511CP6D entry/office lock is the normal step down. Mixing grades by opening rather than buying one grade for the whole facility is how most property managers spend the budget.
14) Does the 5422LN come with a beveled front, and can I get a flat front for an aluminum door?
The standard front on the 5422LN is 2-1/4 x 1-1/8 inches, beveled, which suits a standard beveled wood or hollow metal door edge. Flat fronts are available to order when the edge is square. Lead shielding is also orderable for radiology and imaging rooms, which is worth specifying up front on a healthcare job because it is not a field retrofit.
15) Do I need to specify handing when ordering the Accentra 5422LN?
No. The 5422LN is non-handed, so one lock serves left and right hand doors and you are not stocking two part numbers across a building. The strike is reversible as well. That is the practical difference against decorative leversets, which are frequently handed: the Baldwin Estate 5103 half dummy, for example, is sold as separate left hand and right hand parts.
16) Is a dummy trim lever an equivalent to the Accentra 5422LN?
No. The Accentra 5422LN is a cylindrical lock with a corridor function and a working latch. Dummy trim has no latch and no function beyond a pull. The BEST 9K Series 1DT is a Grade 1 non-keyed heavy duty single dummy trim cylindrical lever, and the BEST 7KC Series 1DT is the Grade 2 medium duty equivalent. Use dummy trim only on an inactive leaf or a false door; it will not latch or lock the opening a 5422LN is specified for.
17) Does a keypad or keyless lever lock cover the same opening as the Accentra 5422LN?
It changes how the door is operated. The Accentra 5422LN is a keyed cylindrical lock with a brass 6-pin cylinder and a corridor function. The Lockey 2835 is a mechanical pushbutton keyless lever lock in passage function for 1-3/16 inch to 2 inch doors with ADA compliance, the Lockey 2835DC adds a double combination, and the Lockey 1150 is a heavy duty mechanical keypad lever set for 1-1/8 inch to 2 inch doors. Those give code entry without a key; the 5422LN keeps the opening on the building keyway.
18) Can a knob lockset be substituted for the Accentra 5422LN on a commercial door?
Only where the door does not need lever operation. The Accentra 5422LN uses a lever handle with the Augusta design. Knob options in the same cylindrical family include the Arrow MK02-TA Grade 1 privacy tudor knob for 1-3/4 inch to 2 inch doors with a fire rating, the Arrow MK33-BD-CS heavy duty asylum ball knob with a Schlage C keyway, and the Arrow HK11 turn-pushbutton entrance ball knob for 1-3/8 inch to 1-3/4 inch doors. Levers are what accessible egress paths are typically specified with, which is the case the 5422LN is built for.
19) Which Grade 2 lever locks have a 2-3/4 inch backset like the Accentra 5422LN?
The Accentra 5422LN uses a 2-3/4 inch standard backset, with 3-3/4 inch and 5 inch extension links available to order. The Cal-Royal AG03 classroom lever is a Grade 2 lock with a 6-pin Schlage C keyway and a 2-3/4 inch backset. The Cal-Royal AG00 entrance lever in the same family uses a 2-3/8 inch backset for 1-3/8 inch to 1-3/4 inch doors, so it will not drop into a door bored at 2-3/4 inch.
20) What finishes does the Accentra 5422LN Augusta lever come in?
Nine finishes are orderable: 605 bright brass, 606 satin brass, 612 satin bronze, 613E dark oxidized satin bronze equivalent, 619 satin nickel, 625 bright chrome, 626 satin chrome, plus BSP black suede powder coat and WSP white suede powder coat. If you are matching existing commercial openings, 626 satin chrome is the usual building-standard choice, and the black and white powder coats are the ones to reach for when the door hardware is meant to disappear into a painted door.
21) Can I match the Augusta lever on doors that do not need a lock?
The Augusta is the lever trim design on the 5422LN, and matching non-keyed openings across a building normally means pairing a keyed corridor lock with passage and dummy trim in the same lever style and finish. Order the non-keyed openings from the same 5400 Series so the lever shape and finish match; specify the identical finish code, since 605 and 606 are PVD as standard and 613 has PVD lifetime finish options, and a PVD lever next to a plated one will not weather the same way.
