Accentra AU-5439LN-626 – Frequently Asked Questions

1) Does the Accentra 5439LN need to be handed when I order it?
No handing to specify. The 5439LN is non-handed and reversible, and the strike is reversible too, so one lock covers left and right hand openings. That makes it easier to stock a few spares across a building without worrying which door they land on.
2) Will the 5439LN latch into my existing strike prep?
Standard build is a 2-3/4 inch backset with a 1/2 inch stainless steel latchbolt throw, a 2-1/4 x 1-1/8 inch beveled front, and a 1-1/4 inch curved lip strike sized for a 1-3/4 inch door. If your frame was prepped for a different lip length, other lip lengths are available to order, and a 3/4 inch latchbolt throw can be specified if your existing prep or gap calls for it. Flat fronts are also an order option if your door is prepped flat rather than beveled.
3) Can I get the Accentra 5439LN with a deeper backset than 2-3/4 inches?
Yes. 2-3/4 inches is standard, and 3-3/4 inch or 5 inch extension links can be ordered for wide stile or glass-front doors where the bore sits further from the edge. Specify the extension when you place the order, because it is not something you can add afterward.
4) Is the Accentra 5439LN approved for a fire-rated door?
It carries a UL/cUL fire rating up to 3 hours and is ANSI/BHMA A156.2 Series 4000 Grade 1 certified. It is also listed as windstorm certified, subject to your local code. For a labeled opening you still need the correct fire-rated frame, strike and closer to keep the assembly compliant.
5) What is a Grade 2 storeroom lever alternative to the Accentra 5439LN?
Two Grade 2 storeroom levers cover the same function. The Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt and a 1-3/8 inch to 1-3/4 inch door thickness range, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever and a 1-3/8 inch to 2 inch range. The Accentra 5439LN is Grade 1 storeroom with an adjustable 1-3/4 inch to 2-1/4 inch door thickness, so on doors thicker than 2 inches the 5439LN is the one that fits.
6) I need a Grade 1 cylindrical lever but the door does not need to be keyed. What should I use instead of the 5439LN?
The 5439LN is a keyed storeroom lock, so for an unkeyed opening look at Grade 1 passage levers: the Falcon K101 is Grade 1 passage with non-handed levers, a 1-3/8 inch to 2-1/4 inch door thickness range and a fire rating; the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage/closet lever, fire rated, for 1-3/4 inch to 2 inch doors; and the Dexter C1000 passage is Grade 1 clutching and non-keyed for 1-3/8 inch to 1-3/4 inch doors. All keep Grade 1 duty without a cylinder.
7) My doors are 2-1/4 inches thick. Which cylindrical levers actually cover that?
The Accentra 5439LN adjusts from 1-3/4 inch to 2-1/4 inch door thickness, and among the comparable levers the Falcon K101 Grade 1 passage lock also reaches 2-1/4 inch. Most others stop earlier: the Corbin Russwin CL3110 and CL33903 top out at 2 inch, and the Cal-Royal AG05 storeroom lever at 1-3/4 inch. For a 2-1/4 inch door needing storeroom function, the 5439LN is the fit.
8) What finishes does the Accentra 5439LN storeroom lever come in, and which ones hold up outdoors?
Nine finish choices 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 black suede and white suede powder coat. PVD is standard on 605 and 606, and PVD lifetime finish options exist for 613, which is what you want on exterior or high-humidity openings where plated brass would tarnish. 626 satin chrome is the usual match for existing commercial hardware.
9) What keeps someone from carding the latch on a storeroom door with this lock?
The 5439LN includes a guardbolt that deadlocks the latchbolt whenever the door is closed, which blocks loiding with a card or shim. Accentra fits the guardbolt as standard on all locking functions in this family, so you do not have to order it separately.
10) Is there a cheaper storeroom lever lock than the Accentra 5439LN for lower traffic doors?
If the door does not need Grade 1, two Grade 2 storeroom levers cover the same function: the Cal-Royal AG05 with a deadlocking latchbolt, rated for 1-3/8 to 1-3/4 inch doors, and the Hager 2580 with the Withnell lever, rated for 1-3/8 to 2 inch doors. Both fit thinner doors than the Accentra, which starts at 1-3/4 inches. Where the door sees constant use or is on a labeled opening, stay with the Grade 1 5439LN.
11) I need an electrified lever lock on the same doors, does the 5439LN do that?
The 5439LN is a mechanical key-operated storeroom lock, not an electrified one. For access control on the same style of opening, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever in 12VAC/DC for 1-3/4 to 2 inch doors. Use the mechanical 5439LN on the storage and back-of-house doors and the electrified lever where the card reader runs.
12) Can the Accentra 5439LN be keyed into an existing master key system?
Standard supply is a brass 6-pin keyed-random cylinder with two keys. A 7-pin cylinder is available to order, and other cylinder and keying options are listed in the Accentra 5400LN series catalog, so a master keyed or keyed-alike order is placed as a cylinder and keying option rather than taken off the shelf.
13) The classroom doors need a different function than storeroom. What Grade 1 lever covers that?
The Dexter C1000 classroom lever is Grade 1, clutching and keyed for 1-3/8 inch to 1-3/4 inch doors, and the C1000 classroom security lever is the Grade 1 version with the classroom security function for the same thickness range. The Accentra 5439LN is a storeroom function lock, where the outside lever stays locked and the key retracts the latch, so the classroom variants are the ones to spec where a teacher needs to lock or unlock the outside lever with a key.
14) Can I use an entrance or office function lever in place of the Accentra 5439LN storeroom lock?
They behave differently. The Falcon B511CP6D is a Grade 2 entry/office lever and the Hager 2525 is a Grade 2 commercial entry lock, both of which allow the outside lever to be left unlocked for daytime traffic. The 5439LN is storeroom function, meaning the outside lever is always locked and entry is by key only. If the room must never be left on free passage, the entry/office locks are not a substitute.
15) What is the closest keyless option to the Accentra 5439LN for a storage room with no key control?
Mechanical pushbutton levers replace the cylinder entirely. 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, the 2835DC adds a double combination on the same range, and the Lockey 1150 heavy duty keypad lever set covers 1-1/8 inch to 2 inch doors with an adjustable backset. The 5439LN instead uses a brass 6-pin keyed cylinder with two keys furnished, which is what you want if the opening has to join an existing keying system.
16) We need matching non-functioning trim on the inactive leaf. Does an Accentra 5439LN work for that?
No, the 5439LN is a keyed storeroom lockset with a working latchbolt. For a pull-only leaf use a dummy trim: the BEST 9K Series 1DT is a Grade 1 non-keyed heavy duty single dummy trim cylindrical lever, and the 7KC Series 1DT is the Grade 2 medium duty single dummy version. Both mount as fixed trim with no latch.
17) Is a residential Grade 3 lever an acceptable substitute for the Accentra 5439LN on a commercial corridor?
They sit in different duty classes. The Cal-Royal AUS00 entrance/office lever is Grade 3 for 1-3/8 inch to 1-3/4 inch doors, the Master Lock BC Series keyed entry lever is Grade 3, and the Kwikset 200BRNL Breton passage lever is Grade 3 for 1-3/8 inch to 1-3/4 inch doors. The Accentra 5439LN is ANSI/BHMA A156.2 Series 4000 Grade 1, UL/cUL fire rated up to 3 hours, which is the specification most commercial and institutional openings call out.
18) What do I order for a psychiatric or utility room instead of the Accentra 5439LN?
Asylum function locks key both sides. The Dexter C1000 asylum (F87) is Grade 1 for 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is a heavy duty asylum/institution/utility lock with a ball knob and a conventional Schlage C keyway cylinder. The Accentra 5439LN is storeroom function with a single cylinder, keyed outside only, and free egress from the inside lever.
19) Can I match the Augusta lever on the non-locking doors nearby?
The 5439LN uses the Augusta lever trim in the Accentra 5400 Series, and the series carries the other common functions, so passage, privacy and classroom doors on the same corridor can be ordered in the same Augusta design and finish. If you only need a Grade 1 passage lever and the trim does not have to match, the Corbin Russwin CL3110 and Falcon K101 are both Grade 1 non-keyed passage cylindrical levers.
20) What is the 5439LN lock body made of, and will it stand up to warehouse traffic?
The mechanism is heavy-gauge steel, zinc-plated and dichromated, and the latchbolt is stainless steel. That plus ANSI/BHMA A156.2 Series 4000 Grade 1 is the spec commercial and industrial openings are written to: schools, hospitals, warehouses, and multi-tenant buildings.
21) Is lead shielding available on the Accentra 5439LN for an X-ray room door?
Yes, lead shielding is an order option on the 5439LN, which is what an imaging or radiology suite door needs. It has to be specified with the order, since the shielding is built into the lock.
22) Restrooms in the same building need locks. Is the 5439LN the right choice there?
No, a restroom wants a privacy function. The Hager 2540 uses the Withnell lever for 1-3/8 inch to 2 inch doors, 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 Baldwin Estate 5103 privacy lever with the 5048 rose is the decorative option. The Accentra 5439LN is a keyed storeroom lock intended for supply, mechanical, and stock rooms.
23) The Accentra 5439LN has Augusta trim. What if I want a decorative lever look instead?
The Accentra 5439LN carries the Augusta lever design in 13 finishes including bright brass, satin nickel, satin chrome, and black and white suede powder coat. For a residential-style appearance, Deltana offers the 6201 Manchester, 6411 Morant, and 6431 Linstead entry levers for 1-3/8 inch to 2 inch doors, and Baldwin lists the Estate 5103 passage lever with the 5048 rose. Those are styled trim; the 5439LN is the Grade 1 storeroom lock for commercial openings.
