Arrow MK01-BD-26D – Frequently Asked Questions

1) Can I use an Arrow MK01 passage knob on a fire rated door?
Yes. Arrow MK Series locks are UL and cUL listed for 3 hour, A label or lesser doors, and they conform to ANSI/BHMA A156.2, Series 4000, Grade 2. The MK01 also carries the F75 ANSI function designation and meets Federal Specification FF-H-106C, which is the line an institutional spec usually wants to see.
2) What backset does the Arrow MK01 come with, and can I get it for a 5 inch backset door?
Standard backset on the MK Series is 2-3/8 inch, with 2-3/4 inch, 3-3/4 inch and 5 inch available. Those two long backsets matter on doors with a wide stile or a glass light where the prep sits farther in from the edge. The latch shipped as standard is the 104 springlatch at 2-3/4 inch backset, so specify the backset you need on the order rather than assuming.
3) Does the Arrow MK01 knob lock, or is it just a latch?
No lock at all. The MK01 is passage function, non-keyed: the latchbolt retracts from the knob on either side and there is no cylinder, no button, no thumbturn. Use it on corridors, hall doors and closets where you want a positive latch and free egress. If you need the door to lock, you want a privacy or an entrance function instead, not this one.
4) Will the Arrow MK01 latch into the strike plate that's already in my frame?
Depends on the strike you have. The MK01 latch throws 1/2 inch, which is standard for a cylindrical springlatch, and it ships with the 300 T-strike measuring 2-3/4 by 1-1/8 inches. If your frame is prepped for an ANSI A115.1 strike, that option measures 4-7/8 by 1-1/4 inches. Every MK strike uses a 1-1/4 inch lip-to-center dimension, so as long as your existing frame prep matches one of those two cutouts you are reusing it, not routing a new one.
5) Is a Grade 2 knob enough for a commercial hallway, or do I need Grade 1?
Grade 2 covers commercial openings where heavy duty hardware is not required, which is most hall, closet and office passage doors. The MK01 is a commercial Grade 2 cylindrical set with a cold rolled steel chassis and zinc dichromate finish for corrosion resistance. On high-traffic openings where you want Grade 1, the Schlage D10S passage latch and the Falcon X101 are both Grade 1 heavy duty cylindrical passage knobsets, and the Corbin Russwin CK4310 is Grade 1 with a 1-3/8 to 2 inch door thickness range if you need a thicker leaf.
6) What is the closest equivalent to the Arrow MK01 passage knob from another brand?
For a like-for-like Grade 2 commercial cylindrical passage knobset, the Corbin Russwin CK4410 with the Global knob matches on grade, passage/closet function and the same 1-3/8 to 1-3/4 inch door thickness range. The Dexter C2000 passage ball knob is also Grade 2, non-keyed, same thickness range. The Falcon W101 is Grade 2 medium duty passage with a fire rating and a 2-3/4 inch backset. All three are cylindrical passage sets, so any of them goes into the same standard bored prep.
7) What should I use instead of the Arrow MK01 on a high-traffic corridor door that needs Grade 1?
Step up to a Grade 1 passage knob. The Schlage D10S passage latch is a Grade 1 heavy duty cylindrical non-keyed knob lock with an Orbit knob. The Falcon X101 is a Grade 1 heavy duty cylindrical passage knobset that is fire rated and covers doors from 1-3/8 inch to 2-1/4 inch. The Corbin Russwin CK4310 is a Grade 1 passage/closet cylindrical lock with a Global knob for 1-3/8 inch to 2 inch doors. The MK01 itself is certified to ANSI/BHMA A156.2, Series 4000, Grade 2.
8) Is a Kwikset 200P Polo passage knob the same thing as an Arrow MK01?
No. The Kwikset 200P Polo is an interior hall and closet passage knob supplied with a 6AL latch and RCS round corner strike, and the 200P-CP ships a round corner adjustable latch and round corner strike. The Arrow MK01 is a commercial cylindrical passage knob certified to ANSI/BHMA A156.2, Series 4000, Grade 2 and UL listed for 3 hour fire doors, with a 300 T-strike measuring 2-3/4 inch by 1-1/8 inch as standard. If the opening is a rated commercial door, the Polo does not answer the same spec.
9) I need the same knob look but the door has to lock - what takes the place of a passage knob?
Passage is latch only, so pick the function the opening needs. For a bed or bath door, the Dexter C2000 privacy knob is a Grade 2 non-keyed privacy/bed/bath cylindrical ball knob for 1-3/8 inch to 1-3/4 inch doors. For a keyed office door, the Dexter C2000 entry/office knob is Grade 2 keyed over the same door range, and the Corbin Russwin CK4851 is a Grade 2 entrance/office cylindrical lock with a Global knob and conventional cylinder. For a storeroom, the Sargent 6G04 is a Grade 2 storeroom/closet knob lock with a single cylinder. The Arrow MK01 is non-keyed with the latchbolt operated by knob either side.
10) The door is thicker than 1-3/4 inch - which passage knob still fits?
The Arrow MK01 fits 1-3/8 inch to 1-3/4 inch doors. For thicker stock, the Corbin Russwin CK4310 Grade 1 passage/closet lock covers 1-3/8 inch to 2 inch and the Falcon X101 Grade 1 passage knobset covers 1-3/8 inch to 2-1/4 inch. Both are cylindrical passage/hall/closet functions, so the opening behaves the same way.
11) Do I have to specify a hand when ordering an Arrow MK01 knobset?
No handing to call out. The MK01 is reversible, so one part number covers left and right hand openings, in-swing or out-swing. For a property manager buying a pallet of passage sets across a building, that means you order quantity and finish and stop thinking about door swing.
12) Will the Arrow MK01 rose cover the old holes left by the knob I'm replacing?
The MK01 rose is 2-9/16 inches in diameter on all three knob designs, and the latch faceplate is 1 by 2-1/4 inches. Since the chassis uses the standard 2-1/8 inch cross bore and 7/8 inch edge bore, it drops straight into any door already prepped for a standard cylindrical lockset. It will not hide a larger existing rose footprint if the old trim was bigger than 2-9/16 inches.
13) I need a bathroom or bedroom lock, not a passage knob. What do I order instead?
Passage function has no locking mechanism, so the MK01 is the wrong part for a bathroom or bedroom. For privacy function in a comparable Grade 2 commercial knob, the Dexter C2000 privacy ball knob is Grade 2 non-keyed for 1-3/8 to 1-3/4 inch doors. Lighter-duty options include the Cal-Royal BER20 and the Pamex FTF Baron, both Grade 3 privacy for the same thickness range.
14) What screws come with the Arrow MK01, and will they work on a hollow metal frame door?
The MK01 ships with both wood and machine screws, so it mounts on a wood door or a hollow metal door without sourcing separate fasteners. The strike still has to match your frame prep, which is where the 300 T-strike at 2-3/4 by 1-1/8 inches or the ANSI A115.1 strike option comes in.
15) Can I standardize a whole building on Arrow MK Series and keep the keyed doors on the same keyway?
That's the point of buying the series. The MK01 itself is non-keyed passage, but the keyed MK functions use a solid brass 6 pin cylinder with the Arrow A keyway, keyed to 5 pin for stock, and they can be masterkeyed, grandmaster keyed and construction masterkeyed. Conventional cylinders are also available in Schlage CS and other competitive keyways, so a building already on another keyway can be matched. Ordering the passage doors from the same series keeps the knob design and finish consistent across keyed and non-keyed openings.
16) What do I order for a closet door that only needs a pull and no working latch?
A dummy knob, not a passage set. The BEST 6K single dummy trim is a Grade 2 medium duty non-keyed cylindrical knob, the Schlage A170 single dummy trim is a Grade 2 heavy duty cylindrical non-keyed knob in the A Series for 1-3/8 inch to 1-7/8 inch doors, and the Cal-Royal BA40 is a dummy cylindrical knob for 1-3/8 inch to 1-3/4 inch doors. An Arrow MK01 has an operating latchbolt worked by the knob from either side and a 300 T-strike as standard, so it needs a bored and mortised door.
17) How does the Falcon W101 compare with the Arrow MK01 for a passage opening?
Both are Grade 2 cylindrical passage knob locks. The Falcon W101 is a W Series medium duty fire rated knob lock with a 2-3/4 inch backset. The Arrow MK01 ships with the 104 springlatch on a 2-3/4 inch backset as standard and is UL listed for 3 hour, A label or lesser doors, with a reversible hand and a 2-9/16 inch rose.
18) Can I use a decorative residential passage knob in place of the Arrow MK01 on a commercial job?
They are built for different specs. The Baldwin Estate 5011 Colonial passage knob with 5058 rose and the Bravura Albany and Lynchburg Grade 2 passage knobsets are all passage/hall/closet knobs, and the Schlage Residential F500 Plymouth with Georgian knob is a combo pack with adjustable backsets and dual strikes for 1-3/8 inch to 1-3/4 inch doors. The Arrow MK01 is designated commercial and is UL and cUL listed for 3 hour, A label or lesser doors, which is what a rated commercial opening is usually written around.
19) Is a keyless combination knob an alternative to a standard passage knobset?
Only if the opening needs a code. The Lockey 3830 is a mechanical keyless combination knob lock with an auto-locking passage function, fitting doors from 1 3/16 inch to 2 inch. The Arrow MK01 has no cylinder at all and simply retracts the latchbolt from either side, so it never secures the door. Pick the Lockey when access must be restricted without keys, and a plain passage knob when free passage is the point.
20) What knob styles and finishes does the Arrow MK01 passage set come in?
Three knob designs, all on the same 2-9/16 inch rose: BD ball knob, DD Darrin knob, and TA Tudor knob. Each is available in eight finishes, 605 bright brass, 606 satin brass, 609 antique brass, 612 satin bronze, 613 oil rubbed bronze, 619 satin nickel, 625 bright chrome and 626 satin chrome. That lets you match the passage doors to keyed openings elsewhere in the same building without changing brands.
21) Which passage knob matches a facility already standardized on BEST or Sargent locks?
For a BEST house, the 8K Series covers Grade 1 heavy duty knob locks and the 6K Series covers Grade 2 medium duty, though the 6K entry cited here is single dummy trim and the 8K is an entrance function. On Sargent, the 8X Line 8XG04 is a Grade 1 heavy duty storeroom/closet knob lock on a 2-3/4 inch backset and the 6 Line 6G04 is Grade 2 standard duty storeroom/closet. The Arrow MK01 sits in the MK Series as a Grade 2 passage knob on a 2-3/4 inch standard backset latch, with a reversible hand.
