Arrow RK12-BD-32D – Frequently Asked Questions

1) Is the Arrow RK12 a storeroom function lock that stays locked from the outside at all times?
Yes. On the RK12 the outside knob is always rigid, so the door is locked to anyone without a key at every moment. A key in the outside knob retracts the latchbolt; the inside knob always turns freely for egress. That is ANSI/BHMA F86 storeroom function, and it's the right pick for mechanical rooms, electrical closets, and storage where the door must never be left unsecured by accident. If you want the door to be lockable and unlockable by the occupant, storeroom is the wrong function.
2) Will the Arrow RK12 fit my existing 2-1/8 inch door prep?
It drops into a standard 2-1/8 inch cross bore through the door, with a 1-3/8 to 1-3/4 inch thickness range covered as standard. Both common backsets are covered, 2-3/8 inch and 2-3/4 inch, so an existing bored opening prepped for a cylindrical knob lock takes it without new boring. Measure from the door edge to the center of the bore to confirm which backset you need before ordering.
3) Will the Arrow RK12 latch into the strike that's already in my frame?
The deadlatch throws 1/2 inch, which is what a standard cylindrical strike is cut for, and it ships standard with an R60 T-strike measuring 2-3/4 x 1-1/8 inches. If your frame already carries a 4-7/8 inch ANSI strike, that option is also covered, as is a 2-1/4 inch full lip strike. Match the strike to what's mortised into your frame and the lock reuses the existing prep. The latch front is 1 x 2-1/4 inches on the 2-3/8 inch backset and 1-1/8 x 2-1/4 inches on the 2-3/4 inch backset, so check which faceplate size is routed into your door edge.
4) Can I key the Arrow RK12 into my existing Schlage C keyway system?
Yes, order the CS cylinder option and the lock comes with a conventional cylinder cut to the Schlage C keyway, so it keys into an existing SC1/C system. The default is Arrow's own "A" keyway with a solid brass 6 pin cylinder and two brass keys. Four cylinder choices in total: standard conventional, CS Schlage C, IC for small format interchangeable core less core, and LC conventional less cylinder.
5) I run an SFIC system already. Can I use my own cores in the Arrow RK12?
Order the IC option and the lock arrives prepped for a small format interchangeable core, less core, so you install your own cores and keep the whole building on one master system. If you're using conventional cylinders from your own stock instead, the LC option ships less cylinder. Both of those are ordered with keying set to None, since there's no cylinder for us to key.
6) Can I get a set of Arrow RK12 storeroom locks all keyed alike for one building?
Keying is a required choice on the RK12: keyed different, keyed alike, or none for the less cylinder options. Keyed alike puts every lock in the order on one key, which is what a property manager wants when maintenance carries a single key for all the storage and utility doors. Keyed different gives each door its own key. There's also a key code field if you need the cylinders cut to an existing code you already have on file.
7) Is the Arrow RK12 heavy duty enough for a commercial storage door, or should I go Grade 1?
The RK12 is a Grade 2 commercial cylindrical lockset, built for multi-family housing and light commercial traffic. That's the right tier for apartment storage rooms, utility closets, and back-of-house doors. For a high-traffic institutional opening where Grade 1 is called out on the drawing, step up to the Sargent 8XG04, a Grade 1 heavy duty storeroom knob lock with a 2-3/4 inch backset. The Sargent 6G04 is the Grade 2 storeroom equivalent if you want a peer at the same grade.
8) I need a storeroom lock for a 2 inch thick door. Will the Arrow RK12 work?
No. The RK12 covers 1-3/8 to 1-3/4 inch doors as standard, so a 2 inch door is outside its range. For a thicker door, the Corbin Russwin CK4851 Entrance/Office cylindrical knob lock covers 1-3/8 to 2 inches, and the Falcon X101 goes to 2-1/4 inches, though both are different functions from storeroom. Measure the actual door edge before ordering, since 1-3/4 inch is the standard commercial thickness and anything thicker usually means a custom or fire-rated slab.
9) What is the closest Grade 2 storeroom knob lock to the Arrow RK12?
The Sargent 6G04 is a Grade 2 storeroom/closet knob lock with a single cylinder, the same grade, function, and single-cylinder keying arrangement as the Arrow RK12 storeroom knob lock. The 6G04 is described as standard duty. Both put a key in the outside knob and leave that knob rigid until it is turned, so an opening specified for a Grade 2 keyed knob storeroom lock accepts either.
10) I need a storeroom knob for a high traffic door - what is a heavier duty option than the Arrow RK12?
The Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet single cylinder knob lock with a 2-3/4 inch backset. The Arrow RK12 is a Grade 2 storeroom knob lock. Where a corridor or stockroom door in a school or hospital is specified Grade 1, the 8XG04 meets it and the RK12 does not; on a multi-family or light commercial door written to Grade 2, the RK12 is the match.
11) Can I use a Dexter C2000 entry knob instead of the Arrow RK12 on a storage room?
The Dexter C2000 entry/office cylindrical ball knob lock is Grade 2 and keyed, like the Arrow RK12, and both are ball knob designs fitting 1-3/8 inch to 1-3/4 inch doors. The functions differ: entry/office lets the inside knob button lock the outside knob so it can be left unlocked, while the RK12 outside knob is always rigid and only a key or the inside knob retracts the latch. If the room must never be left standing open, that behavior is the deciding difference.
12) Is the Imperial USA ED-BKL580 storeroom knob trim a substitute for the Arrow RK12?
No. The Imperial USA ED-BKL580 is knob trim in storeroom function from the ED-500 series, meaning it is the outside trim that mounts to an exit device rather than a lock that works on its own. The Arrow RK12 is a complete cylindrical knob lock with its own latch and strike. If the door has an exit device on the push side, the ED-BKL580 is what you want; if the door is bored 2-1/8 inch for a cylindrical lock, the RK12 is.
13) I need a keyed knob lock for doors thicker than 1-3/4 inch - what covers that?
The Corbin Russwin CK4851 entrance/office cylindrical lock with a global knob and conventional cylinder is listed for 1-3/8 inch to 2 inch doors. The Arrow RK12 fits 1-3/8 inch to 1-3/4 inch doors standard. For a thick solid core or an added fire-rated door leaf beyond 1-3/4 inch, the CK4851 spans the range; note it is entrance/office function, not storeroom.
14) We standardize on interchangeable cores - does anything besides the Arrow RK12 offer that in a knob lock?
The Arrow RK12 is offered as IC SFIC less core, so it takes a small format interchangeable core you supply. Among the alternatives, the Falcon X101 is a Grade 1 heavy duty cylindrical knobset with an interchangeable core, though it is passage/closet function and unkeyed in use. For a keyed storeroom opening on an SFIC system, the RK12 in the IC configuration is the direct answer.
15) The building keys to Schlage C - do I have to change the Arrow RK12 or use a different lock?
The Arrow RK12 is offered with a CS conventional cylinder in the Schlage C keyway alongside the standard Arrow A keyway, so it drops onto a Schlage C system without a different lock. The Cal-Royal BER00, by contrast, is built around a Kwikset keyway, which will not key into a Schlage C system. A locksmith matching an existing bitting should read the keyway before the grade.
16) Does the RK12 knob lock need to be ordered left or right handed?
No handing to specify. The RK12 is non-handed, so one part number works on a left or right hand door swinging in or out. Nothing has to be reversed in the field either.
17) What is the difference between a storeroom knob lock and an entrance/office knob lock?
Storeroom, like the Arrow RK12, keeps the outside knob permanently rigid, so the door cannot be left unlocked. Entrance/office adds a button or turn on the inside that lets the occupant leave the outside knob unlocked during business hours. Pick storeroom for a door that must stay secure at all times and entrance/office for a room people work in. The Dexter C2000 entry/office and Corbin Russwin CK4851 are the entrance/office knob options if that's the function you actually need; if the door only needs to latch and never lock, a passage set like the Dexter C2000 passage knob is the correct part.
18) How far does the Arrow RK12 knob stick out from the door, and how big is the rose?
Total projection from the face of the door is 2-3/4 inches, with a wrought brass rose 2-1/2 inches in diameter. That matters where the door swings against a wall or into a tight corridor, and where you're covering old rose marks on a refinished door. The knob itself is a ball knob.
19) Does the Arrow RK12 come with mounting screws, or do I need to order fasteners separately?
Wood and machine screws are included, so it mounts to a wood door or a metal frame prep without a separate fastener order. Two brass keys come with the keyed cylinder options. Latch and strike are included as well: an R70 deadlatch with 2-3/8 inch backset and an R60 T-strike are the standard pairing.
20) Will the Arrow RK12 hold up in a damp or exterior-facing storage door?
The chassis is cold rolled steel with a zinc dichromate finish for corrosion resistance, and the latchbolt is brass and guarded on all locking functions. For a door that's exposed to weather or washdown, the 630 satin stainless steel or 629 bright stainless finish is the one to specify. Finishes run 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil-rubbed satin bronze, 629 bright stainless, and 630 satin stainless, and every one of them is available with all four cylinder options.
21) I'm replacing a residential-grade keyed knob on an apartment storage door. Is the Arrow RK12 a step up?
Yes, in grade and in function. The RK12 is a Grade 2 commercial lockset with a storeroom function, where a residential keyed entry knob such as the Kwikset 400P-CP is Grade 3 with an entrance function. The practical difference on a storage door: the RK12's outside knob never unlocks without a key, so a resident cannot leave the room open. It reuses the same 2-1/8 inch bore and the same 1-3/8 to 1-3/4 inch thickness range those residential knobs use, so the swap needs no new door prep.
22) What should I use instead of the Arrow RK12 on a classroom door?
The Dexter C2000 series Grade 2 classroom cylindrical ball knob lock is keyed and fits 1-3/8 inch to 1-3/4 inch doors, same grade and door range as the Arrow RK12 storeroom knob. Classroom function lets a key lock and unlock the outside knob so the room can be left open between periods; the RK12 outside knob stays rigid at all times. For a teaching space, the classroom function is the one written on most specs.
23) Which knob lock do I order for the doors that do not need a key, if the storerooms get the Arrow RK12?
The Dexter C2000 series Grade 2 passage ball knob lock is non-keyed and the C2000 Grade 2 privacy ball knob lock is non-keyed, both fitting 1-3/8 inch to 1-3/4 inch doors. That is the same grade and door range as the keyed Arrow RK12, so a property manager can run storeroom, passage, and privacy across one building with a common knob shape and one door prep.
24) Is the Sargent 28C knob trim the same kind of product as the Arrow RK12?
No. The Sargent 28C-KNOB is exit device trim with a knob and rose in entrance function for 1-3/4 inch doors, from the 28 series - it dresses an exit device and has no latch of its own. The Arrow RK12 is a standalone keyed cylindrical storeroom knob lock with an R70 deadlatch and R60 T-strike included. They are ordered for different door conditions and are not interchangeable.
25) Will a Cal-Royal BER00 or Kwikset 400P work where the Arrow RK12 is specified?
Both are keyed knob locks, but they sit a grade lower. The Cal-Royal BER00 is a Grade 3 entrance/office knob lock with a Kwikset keyway fitting 1-3/8 inch to 1-3/4 inch doors, and the Kwikset 400P-CP is a Grade 3 keyed entry knob for the same door range. The Arrow RK12 is Grade 2 with a storeroom function and an Arrow A keyway standard, also available in Schlage C. On a job written to Grade 2 commercial, the Grade 3 knobs do not satisfy the spec, and neither offers the always-rigid storeroom outside knob.
26) What is the difference between the Arrow RK12 and the BEST 8K entrance knob lock?
The BEST 8K series entrance function knob lock is Grade 1 heavy duty with a single cylinder. The Arrow RK12 is a Grade 2 single cylinder storeroom knob. Entrance function on the 8K allows the outside knob to be locked and unlocked from inside; the RK12 outside knob is always rigid and retracts only by key outside or by turning the inside knob. A locksmith standardizing a building picks between them on that function behavior as much as on grade.
27) Which knob lock should I use on a fire rated opening instead of the Arrow RK12?
The Falcon W101 is a Grade 2 medium duty cylindrical knob lock with a fire rating and a 2-3/4 inch backset, and the Falcon X101 is a Grade 1 heavy duty cylindrical knob lock with a fire rating and interchangeable core for 1-3/8 inch to 2-1/4 inch doors. Both are passage/closet latch function, so they are unkeyed - use one of them where the door needs a rated non-locking knob and reserve the keyed Arrow RK12 storeroom lock for the doors that must stay secured.
28) Can I put a Schlage A170 or BEST 6K dummy knob on the inactive door and match the Arrow RK12?
The Schlage A170 is a Grade 2 single dummy trim cylindrical non-keyed knob lock and the BEST 6K series single dummy trim is a Grade 2 medium duty non-keyed cylindrical knob lock. A dummy has no latch and no key - it is a pull only. The Arrow RK12 is a keyed storeroom lock with an R70 deadlatch. On a pair of doors, the dummy goes on the inactive leaf and the RK12 on the active one; do not order a dummy expecting it to secure anything.
29) Is the Lockey 3830 keyless knob lock an alternative to the Arrow RK12 for a storage room?
The Lockey 3830 is a mechanical keyless combination knob lock with an auto-locking passage function, fitting 1 3/16 inch to 2 inch doors. It secures the door by code rather than key, which suits a shared storage room where issuing keys is the problem. The Arrow RK12 is a keyed storeroom lock with a 6 pin solid brass cylinder in the Arrow A keyway, which is what you want when the room needs to fall onto an existing master key system.
30) Corbin Russwin CK4410 versus the Arrow RK12 - what is the difference?
The Corbin Russwin CK4410 is a Grade 2 passage/closet cylindrical lock with a global knob, non-keyed, for 1-3/8 inch to 1-3/4 inch doors. The Arrow RK12 is Grade 2 keyed storeroom for the same door range. Same grade and same door thickness window, so the prep matches; the CK4410 simply always turns from both sides while the RK12 keeps the outside knob rigid. Pick by whether the door has to lock, not by grade.
31) Can I standardize a whole building on Arrow RK Series knobs but use different functions on different doors?
The RK Series covers a range of functions and finishes, and the RK12 is the storeroom version of it. Keeping one series across a property means the roses, knob shape, and door prep match on every opening, so a maintenance crew stocks one set of spare parts. Spec the RK12 on storage, mechanical, and utility doors, and keep the finish consistent across the order (all six finishes carry the same cylinder options). Order the CS keyway or the IC less-core option throughout if you're pulling the whole building onto a single master key system.
