Falcon B511CP6D D 626 – Frequently Asked Questions

1) Will the Falcon B511CP6D lever lock fit a 1-3/8 inch door, or is it only for 1-3/4?
The B511CP6D covers 1-3/8 inch through 2 inch doors, so it handles both older 1-3/8 interior doors and standard 1-3/4 commercial doors without a separate kit. The backset is 2-3/4 inches, which is the usual commercial bore location, not the 2-3/8 residential one.
2) What does entrance/office function actually do on the Falcon B511CP6D?
Entrance/office means the outside lever can be locked, and the key or the inside lever releases it. The inside lever always retracts the latch for free egress. It is the function you want on a tenant suite door or a private office that gets locked when the occupant leaves, not on a classroom or a storeroom that must stay locked at all times. It is keyed, single cylinder, so there is one key cylinder on the outside only.
3) Will this Falcon lever latch into the strike that is already in my frame?
The lock ships with a 1-1/8 x 2-1/4 inch square corner faceplate latch, 1 inch housing diameter, 1/2 inch throw, 2-3/4 inch backset, and a 1-1/4 x 4-7/8 inch ANSI square corner strike with no box. If your frame already has the ANSI 4-7/8 strike prep, it drops straight in. If the existing strike is a radius corner or the smaller 2-3/4 inch T-strike, you will be swapping the strike or filing the frame.
4) Does the B511CP6D take a small format interchangeable core, and can I use my existing SFIC cores?
It is built for interchangeable core, and Falcon states compatibility with SFIC products from other manufacturers, so an existing SFIC keying system can be carried over and the core pulled with a control key for rekeying instead of pulling the lock off the door.
5) Can I put this lock on a fire rated door?
Yes. The B511CP6D is UL listed with a 3-hour A label fire rating, and the lever meets ADA requirements for operable hardware. Between the two it works on rated corridor and stair doors in commercial buildings.
6) What is the closest equivalent to the Falcon B511CP6D entrance lever from another commercial brand?
The Hager 2525 is the nearest match. It is a Grade 2 cylindrical entry lock with a lever handle and a 1-3/8 inch to 2 inch door thickness range, which is the same range the Falcon B511CP6D covers. Both are keyed cylindrical leversets for commercial openings. The Falcon B511CP6D is supplied with a 2-3/4 inch backset and accepts interchangeable cores for re-keying.
7) I need a heavier-duty lever than the Falcon B511CP6D for a high-traffic corridor. What steps up?
The Dexter C1000 series is the Grade 1 step up in a keyed cylindrical lever, with classroom (C1000-CLRM) and classroom security (C1000-CSEC) functions available. The Falcon B511CP6D is a Grade 2 medium duty lockset in entrance/office function. If you want to stay Grade 1 with a different function set, the Corbin Russwin CL3300 series lever trim is also Grade 1.
8) Is the Cal-Royal AUS00 the same thing as the Falcon B511CP6D?
Both are entrance/office function levers, but they are not the same duty class. The Cal-Royal AUS00 is Grade 3 with a solid brass forged body and a 1-3/8 inch to 1-3/4 inch door thickness range. The Falcon B511CP6D is Grade 2 and covers 1-3/8 inch to 2 inch doors with a 2-3/4 inch backset. If your opening is a 2 inch door, the AUS00 range will not reach it.
9) The doors on my job take a 2-3/8 inch backset, not 2-3/4. What keyed lever works there?
The Cal-Royal AG00 entrance lever is a Grade 2 lock built to a 2-3/8 inch backset with a 6-pin Schlage C keyway, keyed different, and fits 1-3/8 inch to 1-3/4 inch doors. The Falcon B511CP6D is supplied with a 2-3/4 inch backset, so it is the choice for standard commercial prep rather than the shallower residential-depth bore.
10) For a storage or supply room where the lever should stay locked outside, what replaces the entrance/office function?
Choose a storeroom function instead. The Hager 2580 with Withnell lever is a Grade 2 storeroom cylindrical lock covering 1-3/8 inch to 2 inch doors, and the Cal-Royal AG05 is a Grade 2 storeroom leverset with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors. The Falcon B511CP6D entrance/office function allows the outside lever to be left unlocked, which a storeroom opening usually should not permit.
11) Do I have to specify handing when ordering this Falcon cylindrical lever?
No. The B511CP6D is non-handed and does not need field disassembly to re-hand, so one part number covers left and right hand openings. That makes it easier to stock a few spares across a building than a handed lock like the Baldwin Estate 5103 half dummy, which is ordered left or right hand specifically.
12) Is Grade 2 enough for my building, or should I be buying Grade 1?
The B511CP6D is certified to ANSI/BHMA A156.2 Series 4000 Grade 2 and is rated medium duty. That suits offices, tenant suites, and back-of-house doors with moderate traffic. For a high-abuse opening, a main entry, or a school corridor, step up to a Grade 1 cylindrical such as the Dexter C1000 Series or the Corbin Russwin CL3100 Series. Grade 1 buys you a higher cycle and strength rating under the same standard.
13) What lever styles and finishes does the Falcon B511CP6D come in?
Two lever designs, Dane (D) and Quantum (Q), each in 613 Satin Bronze Oil-Rubbed or 626 Satin Chrome. All four combinations are orderable. 626 is the standard commercial satin chrome most office buildings are already standardized on; 613 is the darker oil-rubbed bronze for a finish match on wood and darker trim packages.
14) I need a matching passage lever for the closet door next to this office. What pairs with it?
The B511CP6D is keyed entrance/office only, so a non-keyed opening needs a separate lockset. Grade 2 passage options ZenSupply carries include the Hager 2510 with the Withnell lever, which covers 1-3/8 to 2 inch doors like this Falcon does, the Accentra 5301LN Augusta, and the BEST 7KC Series dummy trim if the door needs a pull with no latch at all. Lever profiles will not match the Falcon Dane or Quantum exactly across brands, so if appearance matters on adjacent doors, keep the whole group in one line.
15) What is a comparable entry lever from another brand if I need to match an existing spec?
The closest cross-brand equivalents in the same Grade 2 commercial class are the Hager 2525 entry lever, which shares the 1-3/8 to 2 inch door range, and the Cal-Royal AG00 entrance lever, which is cut for a 2-3/8 inch backset rather than the Falcon's 2-3/4, so check your existing bore before substituting. The Cal-Royal AUS00 is also entrance/office function but Grade 3, which is a step down in duty from this Falcon.
16) I need an electrified lever for an access control tie-in rather than the mechanical Falcon B511CP6D. What works?
The Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever lock operating on 12VAC/DC for doors 1-3/4 inch to 2 inch, available with the NZ lever and D rose. The Falcon B511CP6D is a mechanical, non-electronic lock, so it cannot be released by a card reader or door controller.
17) What should I order instead of the Falcon B511CP6D for a door that never needs to lock?
Use a passage lever. The Hager 2510 is a Grade 2 passage cylindrical lever with the Withnell design and the same 1-3/8 inch to 2 inch door thickness range, and the Accentra 5301LN Augusta is a Grade 2 passage/closet cylindrical lever in the 5300 series. The Falcon B511CP6D is a keyed single cylinder entrance/office lock, so it is over-specified for a closet or corridor door that only needs latching.
18) Can I use a Falcon B511CP6D on the inactive leaf of a pair or as matching trim?
No. The Falcon B511CP6D is a keyed cylindrical lock with a working latch. For inactive leaves and pull-only trim, use a dummy such as the BEST 7KC single dummy trim, a Grade 2 medium duty non-keyed cylindrical lever, or the BEST 9K 1DT, which is the Grade 1 heavy duty equivalent. The Accentra 455LN Augusta is a Grade 1 single dummy option in the 5400 series.
19) Is there a keyless alternative to the Falcon B511CP6D for a door where I do not want to issue keys?
Yes. 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, and the Lockey 1150 is a heavy duty mechanical keypad lever set for 1-1/8 inch to 2 inch doors. The Delaney LP250 is a Grade 2 electronic keypad leverlock. The Falcon B511CP6D is a mechanical keyed lock with no electronics, using a cylinder and key for access.
20) My spec calls for a classroom lever, not entrance/office. What Grade 2 option matches the Falcon B511CP6D prep?
The Cal-Royal AG03 classroom lever in the AG series is a Grade 2 lock with a 6-pin Schlage C keyway, keyed different, on a 2-3/4 inch backset, which is the same backset the Falcon B511CP6D uses. Classroom function keys the outside lever only, with no inside locking button, while the B511CP6D entrance/office function is locked and unlocked from the inside.
21) For a behavioral health or utility room, is the Falcon B511CP6D the right function?
No, those openings normally call for an asylum function. The Dexter C1000 asylum (F87) is a Grade 1 cylindrical lock for 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is a heavy duty Grade 2 asylum lock with a ball knob and conventional cylinder in the Schlage C keyway. The Falcon B511CP6D is entrance/office function, keyed on one side only.
22) Can I use a residential keyed lever like the Kwikset or Master Lock instead of the Falcon B511CP6D in an office building?
Those are a different duty class. The Master Lock BC series RL01 keyed entry lockset is Grade 3, and the Kwikset 200BRNL Breton passage lever is Grade 3 for 1-3/8 to 1-3/4 inch doors. The Falcon B511CP6D is a Grade 2 commercial lockset carrying ANSI/BHMA A156.2 Series 4000 certification with a 3-hour A label UL fire rating, which is what commercial and fire-rated openings generally require.
23) Will these levers sag over time like cheaper leversets do?
Falcon uses individual heavy duty springs for lever return specifically to prevent lever sag, and the trim is through-bolted with a thread sealant coating on the fasteners so it does not work loose under daily use. That is the practical difference between a commercial Grade 2 lock and a residential grade lever on a high-traffic office door.
24) What is the difference between the Falcon B511CP6D and a Deltana entry lever such as the 6201 Manchester?
The Deltana 6201 Manchester is an entry function lever covering 1-3/8 inch to 2 inch doors, as are the 6411 Morant and 6431 Linstead, and these are decorative entry sets. The Falcon B511CP6D is a Grade 2 commercial cylindrical lockset with interchangeable core compatibility and a 2-3/4 inch backset, aimed at keying systems and fire-rated commercial openings.
