Accentra MO-5422LN-626 – Frequently Asked Questions

1) What does the corridor function on the 5422LN actually do at the door?
Corridor function is the classic office/corridor setup: the outside lever is locked or unlocked by key from the corridor side, and the inside lever always retracts the latch for free egress. Paired with the guardbolt, which deadlocks the latchbolt whenever the door is closed, it resists a credit-card style attack on the latch. That makes it a common choice for office suites, tenant doors, and classroom corridors where the door is locked down from outside but never traps anyone inside.
2) Is the Accentra 5422LN fire rated for a 90 minute or 3 hour opening?
The 5422LN is UL/cUL fire rated up to 3 hours, so it covers 20, 45, 60, 90 minute and 3 hour labeled openings. It is also ANSI/BHMA A156.2 Series 4000 Grade 1 and carries a windstorm certification (check your local code for the specific assembly requirement). For a labeled door you still need a fire rated frame, hinges, and a self-closing device on the opening.
3) Will the 5422LN latch into the strike already in my frame?
Standard build is a 1/2 inch stainless steel latchbolt throw with a 2-3/4 inch backset and a 1-1/4 inch curved lip strike sized for a 1-3/4 inch door. If your existing frame has a deeper pocket or the door is set back further, a 3/4 inch throw is available to order, and other strike lip lengths can be specified. All the strikes are reversible, so the frame handing does not force a different part number.
4) Do I have to order the Accentra 5422LN handed?
No. The 5422LN is non-handed, so one part number covers left and right hand openings and the lever can be set for the door you are on during install. That is the reason it works well for a property manager buying a pallet for mixed openings: no counting swings before the order goes in.
5) My door has a 5 inch backset. Can I still use this Accentra cylindrical lock?
Yes, with the right extension. Standard is a 2-3/4 inch backset, and 3-3/4 inch or 5 inch extension links are available to order for deep stile or narrow light doors. That has to be specified when the order is placed, not added later at the door.
6) What cylinder and keying comes with the Accentra 5422LN, and can I key it into my existing system?
It ships with a brass 6-pin keyed-random cylinder and two keys. A 7-pin cylinder is available to order, which is what you specify when you need it to run in an existing 7-pin master key system. Other cylinder and keying options are covered in the 5400LN Series catalog. Order keying with the lock rather than swapping later, since keyed-random stock will not suite to anything you already have.
7) Which alternatives to the Accentra 5422LN still work on a 2-1/4 inch thick door?
The Accentra 5422LN adjusts from 1-3/4 inch to 2-1/4 inch, which is a wider range than most cylindrical levers. Among the comparable Grade 1 levers, the Falcon K101 passage lock is the one that reaches the same 2-1/4 inch maximum, with a range of 1-3/8 inch to 2-1/4 inch. The Corbin Russwin CL3110 passage and the CL33903 electrified lever both stop at 2 inch, and the Dexter C1000 asylum covers 1-3/8 inch to 2 inch. On a full 2-1/4 inch door, the 5422LN and the K101 are the ones that fit without a thickness kit.
8) What is the closest Grade 1 cylindrical lever alternative to the Accentra 5422LN if I need a keyed storeroom function instead of corridor?
The Accentra 5422LN is a Grade 1 cylindrical lever lock in the 5400 Series with a Monroe lever. If the opening needs a keyed storeroom lever instead, the Hager 2580 is a storeroom-function cylindrical lock with the Withnell lever, listed as Grade 2 with a 1-3/8 inch to 2 inch door thickness range. The Cal-Royal AG05 is also a storeroom lever lockset with a deadlocking latchbolt, Grade 2, 1-3/8 inch to 1-3/4 inch doors. Both change the function to storeroom and step down from Grade 1, and neither covers doors up to 2-1/4 inches the way the 5422LN does.
9) I need a non-keyed passage lever on the same doors as the Accentra 5422LN corridor lock - what Grade 1 option matches?
For a passage opening alongside Accentra 5422LN corridor locks, the Falcon K101 is a Grade 1 heavy-duty passage cylindrical lock with non-handed levers and a 1-3/8 inch to 2-1/4 inch door thickness range, which matches the 5422LN's 1-3/4 inch to 2-1/4 inch adjustment at the thick end and is fire rated. The Falcon T101 and the Corbin Russwin CL3110 are also Grade 1 passage cylindrical levers; the CL3110 is vandal resistant, fire rated, and covers 1-3/4 inch to 2 inch doors. The Dexter C1000 passage lever is Grade 1 with clutching levers for 1-3/8 inch to 1-3/4 inch doors.
10) What should I order instead of the Accentra 5422LN for a classroom door?
The Accentra 5422LN is a corridor-function lock, not a classroom function. For a classroom opening, the Dexter C1000 classroom cylindrical lever is Grade 1 with clutching levers and keyed operation for 1-3/8 inch to 1-3/4 inch doors, and the Dexter C1000 classroom security version adds inside keyed control at the same grade and thickness range. The Cal-Royal AG03 is a Grade 2 classroom lever with a 6-pin Schlage C keyway keyed different and a 2-3/4 inch backset, which matches the 5422LN's standard 2-3/4 inch backset.
11) What is the electrified Grade 1 lever equivalent if the Accentra 5422LN opening ties into access control?
The Accentra 5422LN is a mechanical corridor cylindrical lever with a heavy-gauge steel, zinc-plated mechanism and no electrified option in the 5400 Series build. For an access-control opening, the Corbin Russwin CL33903 is a Grade 1 electrified cylindrical lever lock in fail safe configuration at 12VAC/DC for 1-3/4 inch to 2 inch doors, available with the NZ lever and D rose. It requires power and wiring to the door, which the mechanical 5422LN does not.
12) What finishes does the Accentra 5422LN Monroe 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. PVD is standard on 605 and 606, so those two hold up better against tarnish in high touch corridors than a plated brass would. 626 satin chrome is the usual match for existing commercial openings.
13) Should I spec a Grade 1 cylindrical like the 5422LN or is Grade 2 enough for my building?
Grade 1 is the top ANSI/BHMA commercial tier and is what you want on corridor, stairwell, and tenant entry doors that cycle all day, in schools, hospitals, and office towers. The 5422LN is A156.2 Series 4000 Grade 1 with a heavy-gauge steel, zinc plated and dichromated mechanism. For low traffic back of house or light commercial, a Grade 2 lever such as the Hager 2525 entry or Falcon B511CP6D entry/office will do the job at a lighter duty level. Institutional buyers writing a facility standard generally hold the line at Grade 1 on every door in the public path.
14) What are the front and lead shielding options on the 5400LN series lock?
Standard front is a 2-1/4 x 1-1/8 inch beveled face. Flat fronts are available to order when the door edge is square rather than beveled. Lead shielding is also an order option, which is the one to flag if the lock is going into an X-ray or imaging suite wall opening in a healthcare facility.
15) I need matching passage and dummy levers to go with keyed corridor locks. What pairs with the Accentra 5422LN?
The 5422LN is the keyed corridor function in the 5400LN series with Monroe trim, so the matching non-keyed functions come from the same series and lever design if you want the trim to look identical down the hall. If you are filling in non-keyed openings from another line, the Corbin Russwin CL3110 is a Grade 1 fire rated passage/closet lever, and the BEST 9K Series 1DT is a Grade 1 single dummy trim. Those will not match the Monroe lever visually, so use them where the sightline does not matter.
16) Can the Accentra 5422LN be electrified for access control?
No. The 5422LN is a mechanical key operated corridor lock, not an electrified chassis. If the opening needs to drop on a fire alarm or run off a card reader, look at an electrified cylindrical such as the Corbin Russwin CL33903, a Grade 1 fail safe lever at 12VAC/DC, which covers 1-3/4 to 2 inch doors.
17) Is there a lighter-duty lever I can use instead of the Accentra 5422LN on low-traffic interior doors?
Yes. The Accentra 5422LN is a Grade 1 commercial cylindrical lever built for heavy traffic. For low-traffic interior openings, the Hager 2510 is a Grade 2 passage cylindrical lever with the Withnell design for 1-3/8 inch to 2 inch doors, and the Falcon B101 is a Grade 2 medium-duty passage cylindrical lever with a non-handed design. The Design Hardware J75 is a Grade 2 passage lever lockset for 1-3/4 inch doors. All three are Grade 2 rather than Grade 1 and none of them provide the corridor keyed function of the 5422LN.
18) Can I use a Baldwin Estate 5103 or Kwikset Breton lever in place of the Accentra 5422LN?
They are not equivalents. The Accentra 5422LN is a Grade 1 commercial cylindrical lever lock adjustable for 1-3/4 inch to 2-1/4 inch doors with a UL/cUL fire rating up to 3 hours. The Baldwin Estate 5103 is offered in passage, privacy, and half dummy functions with a 5048 rose, and the Kwikset 200BRNL Breton is a Grade 3 passage lever for 1-3/8 inch to 1-3/4 inch doors with the Kwikset 300BRNL as the Grade 3 privacy version. Those are residential-scale trims without the Grade 1 rating or the thicker-door range, so they do not carry a commercial corridor opening.
19) What matching dummy trim goes with Accentra 5422LN levers on inactive leaves?
The Accentra 5422LN is an active corridor lock and does not cover an inactive leaf. For the dummy side, the BEST 9K Series 1DT single dummy trim is a Grade 1 heavy-duty non-keyed cylindrical lever dummy, which holds the same Grade 1 level as the 5422LN. The BEST 7KC Series 1DT single dummy trim is the medium-duty Grade 2 equivalent, and the Callan Bentley is a Grade 2 dummy lever. Lever style and finish will differ from the Monroe trim, so confirm the finish family before pairing.
20) If the opening needs keyless code entry rather than the Accentra 5422LN's keyed cylinder, what lever should I use?
The Accentra 5422LN uses a brass 6-pin keyed-random cylinder with two keys furnished standard. Where an owner wants code entry instead, 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 the 2835DC adding a double combination. The Lockey 1150 is a heavy-duty mechanical keypad lever set covering 1-1/8 inch to 2 inch doors, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. All of these drop the mechanical key cylinder and none reach the 5422LN's 2-1/4 inch door thickness.
21) Is a knob lock like the Arrow MK02 or HK11 an acceptable substitute for the Accentra 5422LN?
Not for the same reasons you would specify the 5422LN. The Accentra 5422LN uses a Monroe lever handle, which is what ADA-driven specifications call for on commercial corridors. The Arrow MK02-TA is a privacy cylindrical lock with a Tudor knob, non-keyed, for 1-3/4 inch to 2 inch doors, and the Arrow HK11 is a turn-pushbutton entrance cylindrical lock with a ball knob and conventional cylinder for 1-3/8 inch to 1-3/4 inch doors. Both are knob trim rather than lever trim and carry different functions than corridor.
22) For a behavioral health or utility room where the Accentra 5422LN corridor function will not work, what lever covers it?
Corridor function on the Accentra 5422LN is intended for general commercial traffic. For asylum or institutional utility openings that need key operation on both sides, the Dexter C1000 asylum lock is a Grade 1 cylindrical lock in F87 function for 1-3/8 inch to 2 inch doors, which is the same Grade 1 level as the 5422LN. The Arrow MK33-BD-CS is a heavy-duty asylum cylindrical lock with a ball knob and a conventional Schlage C keyway cylinder, at Grade 2 and with knob rather than lever trim.
23) What is the difference between the Accentra 5422LN and the Hager 2525 entry lever for an office suite?
The Accentra 5422LN is a Grade 1 corridor cylindrical lever with a Monroe trim, a 2-3/4 inch standard backset, a 1/2 inch stainless steel latchbolt throw with guardbolt, and adjustment for 1-3/4 inch to 2-1/4 inch doors. The Hager 2525 is a Grade 2 commercial cylindrical entry lock with a lever handle for 1-3/8 inch to 2 inch doors. The Falcon B511CP6D is another entry/office option, Grade 2 medium duty. The 5422LN differs in function - corridor rather than entrance/office - and in the higher grade and thicker door capacity.
24) Can I match the Accentra 5422LN with an exit device lever trim on the same corridor?
The Accentra 5422LN is a standalone Grade 1 cylindrical lever lock, not exit device trim. Where the same corridor has a pushpad exit device, the Corbin Russwin 585F715 is a Grade 1 lock lever for the ED8000 pushpad exit device drawn from the CL3300 cylindrical lock series, for 1-3/4 inch to 2 inch doors. The Imperial USA ED-EL500HD is a heavy-duty escutcheon lever trim in entry function for the ED-500 Series. Neither replaces the 5422LN on a plain bored door - they mount to an exit device.
25) What prep does the door need for the 5400LN cylindrical lever lock?
Standard cylindrical prep: a cross bore through the face of the door at a 2-3/4 inch backset and an edge bore for the latch, with the face plate mortised for the 2-1/4 x 1-1/8 inch beveled front. Use the manufacturer template rather than eyeballing it, and thrubolt the chassis through the door so the roses pull tight. Full step by step is in the 5400LN Series installation instructions.
