Falcon B581PD D 626 – Frequently Asked Questions

1) Do I have to order the Falcon B581 left hand or right hand?
No handing to specify. The B581 is non-handed, so one part number works on a left or right swing and you don't take the lock apart in the field to re-hand it. For a property manager stocking spares across a building, that means one lock on the shelf instead of two.
2) What does storeroom function actually do on the Falcon B581 lever lock?
Storeroom means the outside lever is always locked. Entry from outside is by key only, and the inside lever always retracts the latch for free egress. There is no button or thumbturn to leave it unlocked, so a tenant or student can't prop the door into an unlocked state. That is the function you want on a utility room, an electrical closet, a stockroom, or a building's mechanical space. If you need staff to be able to leave the door unlocked during business hours, storeroom is the wrong choice and an entrance/office function lock is what you want.
3) Can I put the Falcon B581 on a fire rated door?
Yes. The B581 is UL listed with a 3-hour A label fire rating, and it is ANSI/BHMA A156.2 Series 4000 Grade 2 certified. Storeroom function also keeps free egress from the inside, which is what a rated opening in a corridor needs.
4) Should I order the Falcon B581 with a core installed or less cylinder?
Three cylinder choices. A 6 pin conventional cylinder comes ready to go. Less 6 pin cylinder ships the lock prepped for a conventional cylinder you supply. Less SFIC ships it prepped for a small format interchangeable core, which is what you pick if your building is already on an SFIC system and your locksmith keys the cores in house. If you take either less-cylinder option, select None on the keyway so the order doesn't try to key a lock with no cylinder in it.
5) Can the Falcon B581 be keyed into my existing Schlage C master key system?
Yes, C Schlage is one of the keyways offered, along with G, E, H, K, L, N and P. Choosing C Schlage lets the B581 drop into a building already keyed on that system rather than adding a second key ring for the maintenance staff. With the SFIC version, re-keying later is a core swap with a control key instead of pulling the lock off the door.
6) What is the closest cross-brand equivalent to the Falcon B581 storeroom lever lock?
The Hager 2580 with Withnell lever is the nearest match: it is also a Grade 2 storeroom-function cylindrical lock, and it carries the same 1-3/8 inch to 2 inch door thickness range as the Falcon B581. Both are keyed cylindrical leversets meant for the same medium-duty commercial storeroom opening, where the lever is always locked from outside and the key retracts the latch. The Falcon side adds interchangeable core compatibility, so a facility already keyed on SFIC can rekey without pulling the lock; the Hager 2580 is described as a storeroom lock without that core system called out.
7) Is there another Grade 2 storeroom lever that fits a 2-3/4 inch backset opening?
The Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt, and it is the other storeroom-function leverset in the same grade class as the Falcon B581. The difference that decides the opening is door thickness: the Cal-Royal AG05 covers 1-3/8 inch to 1-3/4 inch, while the Falcon B581 covers 1-3/8 inch to 2 inch. On a 1-3/4 inch door either will land; on a 2 inch door only the Falcon range reaches. The Falcon B581 ships on a 2-3/4 inch backset with a 1-1/8 inch by 2-1/4 inch square corner faceplate latch.
8) What should I use instead of a storeroom lever on a door that only needs to latch, not lock?
Storeroom function on the Falcon B581 means keyed operation from the outside, which is wasted on a corridor or closet door that just needs a latch. For those openings the Hager 2510 is a Grade 2 passage cylindrical lever with the Withnell design, covering 1-3/8 inch to 2 inch door thickness, the same range the Falcon B581 spans. In the same grade class the Accentra 5301LN Augusta and the Accentra 4601LN are also Grade 2 passage/hall/closet cylindrical levers. Passage function has no cylinder at all, so there is no keyway or keying decision to make on the order.
9) I need a keyed lever where the outside can be left unlocked during business hours - what changes from a storeroom lock?
Storeroom function on the Falcon B581 keeps the outside lever locked at all times, with the key retracting the latch, so there is no way to leave it free-turning for the day. An entrance or office function does that instead. The Hager 2525 is a Grade 2 commercial cylindrical entry lock with a lever handle covering 1-3/8 inch to 2 inch door thickness, and the Cal-Royal AG00 entrance lever is a Grade 2 with a 6-pin Schlage C keyway and a 2-3/8 inch backset. The Dexter C1000 entry/office lever is the Grade 1 version of the same idea, covering 1-3/8 inch to 1-3/4 inch.
10) The spec on my drawing calls for Grade 1 on a storeroom-type opening - what do I move up to?
The Falcon B581 is certified to ANSI/BHMA A156.2 Series 4000 Grade 2 for medium-duty use, so it will not satisfy a Grade 1 line on a drawing. In the heavy-duty cylindrical lever class, the Dexter C1000 asylum/institution/utility lock is Grade 1 and covers 1-3/8 inch to 2 inch door thickness, matching the Falcon range, and it is keyed on both sides rather than storeroom. The Corbin Russwin CL3100 series is Grade 1 and fire rated but is a passage/closet function on a 1-3/4 inch to 2 inch door, so it is only a Grade 1 answer where the opening does not need a cylinder.
11) Which storeroom-class alternatives still work on a 1-3/8 inch door?
Thin doors narrow the field fast. The Falcon B581 adjusts from 1-3/8 inch to 2 inch, so it lands on a 1-3/8 inch leaf. Among comparable commercial leversets, the Hager 2580 storeroom lock and the Hager 2510 passage lever also start at 1-3/8 inch and run to 2 inch, and the Cal-Royal AG05 Grade 2 storeroom lockset covers 1-3/8 inch to 1-3/4 inch. What will not fit is anything starting at 1-3/4 inch, including the Arrow GL01 Grade 2 passage lock at 1-3/4 inch to 2 inch and the Corbin Russwin CL3110 at 1-3/4 inch to 2 inch. Confirm the leaf thickness before substituting.
12) I need an electrified lever for access control on this opening - what replaces a mechanical storeroom lock?
The Falcon B581 is a mechanical, non-electronic lock, so it cannot be tied into an access control system. The electrified equivalent in cylindrical lever form is the Corbin Russwin CL33903, a Grade 1 fail safe electrified cylindrical lever running on 12VAC/DC for 1-3/4 inch to 2 inch doors, offered with the NZ lever and D rose and in a keyed 12VAC/DC configuration. Fail safe means the lever unlocks on loss of power, which is the opposite of the always-locked outside lever the Falcon B581 provides, so confirm which state the opening is required to fail to.
13) What door prep does a Falcon B581 cylindrical lever need?
Standard cylindrical prep: a 2-1/8 inch bore through the face of the door and a 1 inch edge bore for the latch. If your door already carries a cylindrical knob or lever with a matching backset, the B581 goes into the same holes. It is through-bolted with thread sealant on the trim, which is what stops the roses backing off on a high-traffic door.
14) Is a Grade 2 lock like the B581 enough for a storeroom, or do I need Grade 1?
Grade 2 is a medium duty rating, which suits interior storerooms, utility rooms, and common area doors in retail, multi-family and office buildings. Where the door sees constant public traffic or is a known abuse point, step up to a Grade 1 storeroom lock. The Corbin Russwin CL3300 Series is a Grade 1 cylindrical lever line, and the BEST 9K Series is another heavy duty Grade 1 cylindrical family. If Grade 2 is your target and you want an alternative brand, the Hager 2580 with the Withnell lever is also a Grade 2 storeroom lever for 1-3/8 to 2 inch doors, and the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt for 1-3/8 to 1-3/4 inch doors.
15) What is the difference between the Dane and Quantum levers on the Falcon B581?
Dane and Quantum are the two trim designs the B581 is built with, and both are offered in every finish the lock comes in: 605 bright brass, 606 satin brass, 613 satin bronze oil-rubbed, 625 bright chrome and 626 satin chrome. Function and prep are identical between them, so pick whichever matches the lever profile already on your other doors. If you are standardizing a building, note the choice on the order along with the finish so replacements years from now still match.
16) Is the Falcon B581 lever ADA compliant for a public building?
Yes, the B581 meets ADA standards with a lever design that operates without grasping or twisting, and an abrasive strip is available as an option for marking a hazardous entrance by touch. That matters on government, healthcare, and educational openings where the lock has to be operable by anyone approaching the door.
17) I need the same lever on doors that shouldn't lock. What matches a Falcon B581 on the passage doors?
The B581 is keyed storeroom only, so for a closet or corridor door that just needs a latch, you need a passage function lever. Options we carry include the Hager 2510 Grade 2 passage lever for 1-3/8 to 2 inch doors, the Accentra 5301LN Augusta Grade 2 passage lever, and the BEST 7KC Series medium duty Grade 2 dummy trim where the door needs a lever with no latch at all. Trim profiles will not match Falcon's Dane or Quantum lever exactly, so if visual consistency across a floor matters, keep the passage doors within the Falcon B Series.
18) Will a Falcon B581 accept interchangeable cores from another manufacturer?
Ordered less SFIC, the B581 takes small format interchangeable cores, including cores from other manufacturers, so a facility already running an SFIC program can pin the cores it already stocks and drop them in. Re-keying after that is a core pull, not a lock removal.
19) Can I use a classroom lever in place of a storeroom lever on a school storage room?
They are not the same function and swapping them changes who controls the door. The Falcon B581 storeroom function keeps the outside lever locked continuously so the door secures behind anyone who leaves. The Cal-Royal AG03 classroom lever is a Grade 2 with a 6-pin Schlage C keyway and a 2-3/4 inch backset, matching the Falcon B581 backset, but classroom function lets the key set the outside lever free for a period of time. The Dexter C1000 classroom lever is the Grade 1 clutching version, and the Dexter C1000 classroom security lever adds an inside keyed control, both covering 1-3/8 inch to 1-3/4 inch doors. Pick storeroom when the door must never be left unlocked.
20) Is a dummy lever a substitute for a storeroom lock on the inactive leaf of a pair?
No - a dummy has no latch and no cylinder, so it cannot secure or hold a door. The Falcon B581 is a keyed cylindrical storeroom lock with a 1/2 inch throw latch on a 2-3/4 inch backset. If the inactive leaf only needs a matching pull, the BEST 7KC series single dummy trim is a Grade 2 medium-duty non-keyed cylindrical lever dummy, the closest in grade and duty to the Falcon B581, and the BEST 9K series 1DT is the Grade 1 heavy-duty dummy. The Accentra 455LN Augusta is a Grade 1 single dummy cylindrical lever. Use a dummy alongside a storeroom lock, not in place of one.
21) I want a knob instead of a lever on a utility room - what is comparable to the Falcon B581?
The Falcon B581 is lever trim only and is ADA compliant on that basis. For knob trim in the same commercial cylindrical family, the Arrow MK33-BD is a Grade 2 heavy duty asylum/institution/utility cylindrical lock with a ball knob and a conventional cylinder in Schlage C keyway, which is the utility-room counterpart in knob form, though asylum function is keyed on both sides rather than storeroom. The Arrow HK11 is a Grade 2 turn-pushbutton entrance cylindrical lock with a ball knob for 1-3/8 inch to 1-3/4 inch doors. Note that knob trim does not meet the ADA operation the lever design on the Falcon B581 provides.
22) Does an escutcheon lever trim do the same job as a Falcon B581 storeroom lock?
No. The Imperial USA ED-EL500HD is heavy duty escutcheon lever trim in an entry function - it is trim that mounts to an exit device, not a standalone bored lock. The same is true of the Corbin Russwin 585F715 lock lever, which is a lever for the ED8000 pushpad exit device and the CL3300 cylindrical lock series on 1-3/4 inch to 2 inch doors. The Falcon B581 is a complete cylindrical bored lockset with its own latch and strike, installed in a 2-1/8 inch bore with a 1 inch edge bore. If the door already carries an exit device, trim is what you order; if the door is bare, you need the full lockset.
23) My Yale hardware is keyed on Schlage C - does that affect choosing a Falcon B581?
Not adversely. The Falcon B581 is ordered with a Schlage C keyway among its keyway choices, so a facility standardized on Schlage C can key it into the existing system directly, and its interchangeable core compatibility lets cores be swapped without removing the lock. Where existing Yale hardware needs to accept a Schlage cylinder instead, the Accentra 107S is a Schlage cylinder adapter kit for Yale hardware. Adapting one lock and specifying a new one are separate decisions - the adapter does not change what function the door gets.
24) Can I use a privacy lever on a single-occupancy room instead of a storeroom lock?
Only if the room does not need keyed control. Privacy function locks from the inside with a thumbturn and has no key on the outside, which is why the Arrow MK02-TA privacy lock with tudor knob and the Hager 2540 privacy lock with Withnell lever, a Grade 2 for 1-3/8 inch to 2 inch doors, suit restrooms and changing rooms rather than stock rooms. The Falcon B581 is keyed single cylinder storeroom, so staff or a locksmith can always get in with a key. On a room holding equipment or supplies, storeroom is the function that matches.
25) Why do the levers on our old locksets droop, and does the Falcon B581 do the same?
Lever sag comes from a weak return spring letting the lever settle below horizontal over thousands of cycles. The B581 uses individual heavy duty springs for lever return specifically to prevent that, which is the failure mode most often reported on medium duty levers in multi-family and retail corridors.
