Arrow MK02-BD-26D – Frequently Asked Questions

1) What backset does the Arrow MK02 come with, and can I get it for a 5 inch backset door?
Standard is a 2-3/8 inch backset, with 2-3/4 inch, 3-3/4 inch and 5 inch backsets available on the MK Series. The 2-3/8 and 2-3/4 options cover almost every door you will meet; the 3-3/4 and 5 inch versions are for wide-stile or narrow-frame situations where the bore sits further from the edge.
2) Will an Arrow MK02 latch drop into my existing strike without re-cutting the frame?
The MK02 latch throws 1/2 inch and ships with a 300 T-strike measuring 2-3/4 by 1-1/8 inches, with a 1-1/4 inch lip-to-center. If your frame is already prepped for a standard T-strike of that size it drops straight in. Frames cut for the larger ANSI A115.1 strike need the optional 4-7/8 by 1-1/4 inch strike instead, which is available on the MK Series.
3) How does the Arrow MK02 privacy function actually work if someone locks themselves in a bathroom?
Push button on the inside knob locks the outside knob. From outside, an emergency release unlocks it, which is what you want for a bathroom or bedroom in a rental or a care facility. It also unlocks by turning the inside knob or by closing the door, so it will not stay locked once the room is vacated. There is no key and no cylinder on this one.
4) I need a privacy knob for a door thicker than 1-3/4 inch - what works where the Arrow MK02 does not?
The Deltana 6112 St. Thomas knob privacy covers doors 1-3/8 inch to 2 inch, so it reaches openings above the Arrow MK02's 1-3/8 inch to 1-3/4 inch range while keeping the privacy/bed/bath function. Measure the leaf at the lock stile before ordering; a thick solid-core or a door with an added face panel is where this comes up.
5) What is the closest equivalent to the Arrow MK02 privacy knob from another brand?
The Dexter C2000 Series privacy cylindrical ball knob lock is the nearest match. Both are Grade 2 privacy/bed/bath cylindrical knob locks, both are non-keyed, and both fit doors 1-3/8 inch to 1-3/4 inch thick. The Arrow MK02 is an F76 privacy function with a 1/2 inch latch throw and a 2-9/16 inch rose. The Dexter privacy knob is described as non-clutching. If you are matching a privacy knob on a bed or bath door and want the same grade and the same door thickness window, that is the direct swap.
6) Is there a lower-grade privacy knob than the Arrow MK02 for light residential-style doors?
Yes. The Cal-Royal BER20 privacy knob lock is Grade 3 and fits doors 1-3/8 inch to 1-3/4 inch, and the Pamex FTF Baron knob lockset in privacy function is also Grade 3 for the same 1-3/8 inch to 1-3/4 inch door range. The Arrow MK02 is Grade 2 and carries a UL listing for 3 hour, A label or lesser doors. The door thickness window is identical across all three, so the swap is about the grade and fire listing you need at that opening, not about the door prep.
7) I need a knob lock for a high-traffic corridor door instead of a bathroom door - what steps up from the Arrow MK02?
Move to a Grade 1 cylindrical knob. The Schlage D10S passage latch is a Grade 1 heavy duty non-keyed cylindrical knob lock with an Orbit knob, the Falcon X101 is a Grade 1 heavy duty cylindrical passage knobset with an interchangeable core covering doors 1-3/8 inch to 2-1/4 inch, and the Corbin Russwin CK4310 is a Grade 1 passage/closet cylindrical lock for doors 1-3/8 inch to 2 inch. The Arrow MK02 is Grade 2 and privacy function, built around a 1/2 inch throw latch. Those Grade 1 options are passage function, so they hold no lock at the opening - pick them where cycle life matters more than privacy.
8) Which knob locks look like the Arrow MK02 but will not work on a bathroom door?
Dummy trim is the common mix-up. The Schlage A170 single dummy trim is a Grade 2 non-keyed cylindrical knob, the BEST 6K single dummy trim is a Grade 2 non-keyed cylindrical knob, and the Cal-Royal BA40 dummy knob cylindrical lock fits doors 1-3/8 inch to 1-3/4 inch. All three read as Grade 2 non-keyed cylindrical knobs on paper, the same words that describe the Arrow MK02. The difference is that dummy trim has no latch and does not turn; the MK02 is a privacy function whose latch bolt is operated by the knob from either side, with the outside knob locked by a push button inside. A bath door needs the latch and the button.
9) Do I have to specify handing when ordering an Arrow MK02 knob lock?
No handing to specify. The MK02 is reversible, so one part number works on a left or right hand door and you can stock a single item across a building instead of splitting inventory by swing.
10) Is a Grade 2 knob lock like the Arrow MK02 enough for a commercial building, or do I need Grade 1?
Grade 2 is the right call for commercial openings that are not taking heavy public traffic: offices, restrooms in low-traffic areas, back-of-house doors, multi-family units. The MK Series was built for exactly that, where heavy duty Grade 1 hardware is more than the door needs. For a high-cycle opening, step up to a Grade 1 cylindrical knob such as the Schlage D Series D10S or the Falcon X101, both heavy duty Grade 1. Note both of those are passage function, not privacy.
11) What knob styles and finishes does the Arrow MK02 come in?
Three knob designs, all on a 2-9/16 inch rose: BD ball knob, DD Darrin knob and TA Tudor knob. Every one of them is offered in eight finishes: 605 bright brass, 606 satin brass, 609 antique brass, 612 satin bronze, 613 oil-rubbed satin bronze, 619 satin nickel, 625 bright chrome and 626 satin chrome. If you are matching existing openings in a building, the 2-9/16 inch rose is the number to check against your current trim so you are not left with a witness mark on the door face.
12) What is a comparable Grade 2 commercial privacy knob lock if the Arrow MK02 knob style is not what I want?
The Dexter C2000 Series privacy ball knob is the closest match: Grade 2, privacy/bed/bath function, non-keyed, 1-3/8 to 1-3/4 inch door range, same as the MK02. Stepping down, Cal-Royal BER20 and the Pamex FTF Baron are Grade 3 privacy knobs on the same door thickness range, lighter duty than the Arrow. For a residential-look privacy knob, the Deltana 6112 St. Thomas covers 1-3/8 to 2 inch doors.
13) Does the Falcon W101 substitute for the Arrow MK02 on a fire-rated door?
Only if the opening takes a passage function. The Falcon W101 is a Grade 2 medium duty cylindrical knob lock carrying a fire rating, in passage/closet latch function with a 2-3/4 inch backset. The Arrow MK02 is Grade 2 and UL listed for 3 hour, A label or lesser doors, but it is a privacy function with a push button inside. Both suit a rated opening; the W101 will not give you a lockable bath door.
14) What is the difference between the Arrow MK02 and a keyed knob lock like the Dexter C2000 entry or Cal-Royal BER00?
The Arrow MK02 is non-keyed. It is a privacy function - the outside knob is locked by a push button inside and unlocked by an emergency release outside. The Dexter C2000 entry/office ball knob is a Grade 2 keyed lock for doors 1-3/8 inch to 1-3/4 inch, and the Cal-Royal BER00 is a Grade 3 entrance/office knob lock with a Kwikset keyway for the same door range. If the opening needs a key on the outside, the entrance/office locks are the ones to specify; if it needs a thumb-turn style privacy button with no key in the system, the MK02 is the function.
15) Can I standardize a whole floor on one Arrow MK Series knob, or do I need to mix brands by function?
For privacy openings the Arrow MK02 covers bed and bath at Grade 2, non-keyed, on doors 1-3/8 inch to 1-3/4 inch. Within a single facility that also has corridor and storeroom doors, the functions that sit alongside it come from the other lines: the Sargent 6G04 is a Grade 2 storeroom/closet knob lock with a single cylinder, and the Corbin Russwin CK4410 is a Grade 2 passage/closet knob for doors 1-3/8 inch to 1-3/4 inch. Holding every opening at Grade 2 keeps the specification consistent even where the function changes.
16) Is a Baldwin or Emtek knob an alternative to the Arrow MK02 for a decorative interior door?
For a privacy opening, the Baldwin Estate 5077 Bethpage privacy knob with R027 rose and the Baldwin Estate 5000 Baltimore knob with 5148 rose are privacy function and carry a 2-3/8 inch backset with a full lip strike on the 5000. The Emtek Arts and Crafts hammered egg knobset and the Emtek Classic Brass crystal Georgetown and Providence knobsets are dummy function, sold in pairs, so they mount as trim only and hold no latch. The Arrow MK02 is a Grade 2 privacy knob with a 2-9/16 inch rose and a T-strike measuring 2-3/4 inch by 1-1/8 inch. Where a decorative face is the priority the Baldwin privacy knobs cover the same function; the Emtek dummy sets do not.
17) What screws and mounting hardware come with the Arrow MK02, and does it work on both wood and metal doors?
Both wood screws and machine screws are supplied, so the same lockset mounts to a wood door or a hollow metal door without sourcing separate fasteners. The chassis and latch housing are cold rolled steel with a zinc dichromate finish for corrosion resistance, and the latch itself is brass.
18) What size latch faceplate mortise do I cut in the door edge for an Arrow MK02?
The standard faceplate on the 2-3/8 inch backset latch is 2-1/4 by 1 inch with a flat front. Go to the 2-3/4 inch backset and the standard faceplate is 2-1/4 by 1-1/8 inches with a beveled front, 1/8 inch in 2 inches, which is the one to use on a beveled door edge. Faceplate material is brass, bronze or stainless steel.
19) Can I keep the Arrow MK02 privacy knob and add keyed Arrow locks on the same building master key system?
The MK02 itself is non-keyed, so it takes no cylinder and sits outside the key system entirely, which is normal for a bathroom or bedroom door. The keyed MK Series functions use a solid brass 6 pin cylinder in the Arrow A keyway, keyed to 5 pin for stock, and can be masterkeyed, grandmaster keyed and construction masterkeyed. Cylinders are also available in Schlage C keyway and other competitive keyways, so an MK Series job can be built into an existing system.
20) What replaces an Arrow MK02 privacy knob when the door needs a lever instead for ADA access?
Within the knob comparables the function equivalents stay knobs, so the answer at that opening is a lever-trim product rather than a substitute knob. If the knob is acceptable and the concern is the operation, the Arrow MK02 is reversible in handing and its latch bolt is operated by the knob from either side, which lets the same part serve either swing. For a keyed corridor opening on the same run, the Corbin Russwin CK4851 is a Grade 2 entrance/office cylindrical lock with a Global knob and a conventional cylinder for doors 1-3/8 inch to 2 inch.
