Cal-Royal BA40-32D – Frequently Asked Questions

1) Will the Cal-Royal BA40 fit a 1-3/4 inch commercial door?
Yes, the BA40 adjusts across 1-3/8 inch to 1-3/4 inch door thickness, which covers standard commercial 1-3/4 inch doors as well as the thinner 1-3/8 inch interior doors common in older buildings. Anything thicker than 1-3/4 inches is outside the range.
2) Does the Cal-Royal BA40 dummy knob need a new door prep, or will it drop into an existing knob bore?
It uses standard cylindrical prep: a 2-1/8 inch cross bore through the face and a 1 inch edge bore. If the door already has a bored knob hole cut to those dimensions, the dummy trim mounts to it without new boring. Because it's a dummy, nothing goes into the frame on that side.
3) What else can I use instead of the Cal-Royal BA40 single dummy knob?
For a like-for-like commercial single dummy, the Schlage A170 is a Grade 2 heavy duty single dummy trim fitting 1-3/8 inch to 1-7/8 inch doors, and the BEST 6K Series single dummy trim is a Grade 2 medium duty option. If the look matters more than the commercial grade, the Bravura Biloxi round trim dummy knobset is Grade 2, and Omnia offers solid brass single dummy knobs such as the 458/0 and the 442/00. Note the Emtek Arts and Crafts Hammered Egg and Classic Crystal Georgetown and Providence dummies ship as pairs, two knobs, not the single-side trim the BA40 is.
4) I ordered a dummy knob but the door needs to latch closed. What should I get instead?
You need a passage function, not a dummy. Staying in Grade 2 knob trim, the Corbin Russwin CK4410 passage/closet knob covers 1-3/8 inch to 1-3/4 inch doors, the Arrow MK01 and RK01 passage knobs cover the same thickness range, and the Falcon W101 is a Grade 2 passage/closet knob with a 2-3/4 inch backset and a fire rating. For heavier traffic, the Schlage D10S and Falcon X101 are Grade 1 passage knobs.
5) The door needs a knob that actually turns and retracts a latch, not a dummy - what do I order instead of the BA40?
The BA40 is non-keyed dummy trim, so it does not operate a latch at all. For a hall, closet or corridor door that needs a working latch with no lock, a passage function knob is the part: the Falcon W101 is a Grade 2 cylindrical passage/closet knob lock with a 2-3/4 inch backset, matching the BA40 2-3/4 inch backset prep, and it is fire rated. The Corbin Russwin CK4410 is another Grade 2 passage/closet cylindrical knob covering 1-3/8 inch to 1-3/4 inch doors, the same thickness range the BA40 covers. Dexter C2000 passage is a further Grade 2 option on that same thickness range.
6) What is the closest equivalent to a Cal-Royal BA40 single dummy knob from another commercial brand?
The Schlage A170 is the nearest peer. Both are Grade 2 cylindrical non-keyed knob locks in dummy function, and both fit a range starting at 1-3/8 inch door thickness - the BA40 covers 1-3/8 inch to 1-3/4 inch, the A170 covers 1-3/8 inch to 1-7/8 inch, so the Schlage carries slightly further on thicker doors. The A170 is from the Schlage A Series and is rated heavy duty. If the surrounding doors are already Cal-Royal Barrington BA trim, the BA40 keeps the knob shape and finish consistent; if the building is standardized on A Series, the A170 matches what is already hung.
7) Can I use an Emtek or Omnia dummy knob in place of the Cal-Royal BA40 on a commercial door?
They are dummy function, but they are a different class of part. The BA40 is a commercial cylindrical lockset rated to BHMA/ANSI A156.2 Grade 2 with wrought brass, bronze or stainless steel exposed trim. The Omnia 434/0 and Omnia 442/00 are solid brass traditional dummy latchsets, and the Emtek Hammered Egg and Georgetown crystal dummy knobsets are decorative dummy sets sold as a pair - two knobs, where the BA40 is single dummy trim for one face of the door. On a spec that calls for a Grade 2 commercial rating, the residential and decorative dummies do not carry that rating; on a residential or interior decorative opening they are the intended look.
8) The door has to lock and key - what replaces a Cal-Royal BA40 when the room needs to secure?
The BA40 is non-keyed and cannot be keyed. For a keyed commercial knob at the same Grade 2 level, the Sargent 6G04 is a Grade 2 storeroom/closet knob lock with a single cylinder, and the Dexter C2000 entry/office is a Grade 2 keyed ball knob covering 1-3/8 inch to 1-3/4 inch, the BA40 thickness range. Stepping to Grade 1, the Sargent 8XG04 is a heavy duty storeroom/closet single cylinder knob with a 2-3/4 inch backset, which matches the BA40 2-3/4 inch backset prep, and the BEST 8K Series is a Grade 1 heavy duty entrance knob.
9) Our doors are 2 inches thick - the Cal-Royal BA40 tops out at 1-3/4 inch. What knob goes on them?
The BA40 adjusts for 1-3/8 inch to 1-3/4 inch. For thicker leaves, the Corbin Russwin CK4310 passage/closet covers 1-3/8 inch to 2 inch, the Corbin Russwin CK4851 entrance/office covers the same 1-3/8 inch to 2 inch, and the Falcon X101 passage knobset reaches 1-3/8 inch to 2-1/4 inch. On the decorative side, the Deltana 6171 Round Knob entry and Deltana 3381 Egg Knob entry both cover 1-3/8 inch to 2 inch. Note these are working functions rather than fixed dummy trim.
10) Do I have to specify left hand or right hand when ordering a Cal-Royal BA40?
No handing to call out. The BA40 is completely reversible, so the same part works on a left or right hand door. That's useful when you're stocking spares for a building and don't want two part numbers on the shelf.
11) What backset and latch face does the Cal-Royal Barrington BA series use, so my other doors match?
Standard backset on the BA series is 2-3/4 inches, which is the usual commercial prep. The functioning locks in the series take a 2-1/4 x 1-1/8 inch faceplate at 2-3/4 inch backset, or 2-1/4 x 1 inch at 2-3/8 inch backset, and the strike is the ANSI standard 4-7/8 x 1-1/4 inch, with T strike and full lip strike available on request. The BA40 dummy itself has no latch or strike, so it just needs the bore to line up.
12) Can I use a Cal-Royal BA40 to match the knobs on the rest of my Barrington BA series openings?
That's exactly what it's for. The BA40 is the dummy member of the Barrington BA series, so on an inactive leaf or a false door you get the same knob and rose profile as the working locks around it, in the same US3, US10, US10B or US32D finishes. Pick the finish already on the building and the openings read as one set.
13) Is there another Grade 2 commercial dummy knob besides the Cal-Royal BA40 and the Schlage A170?
Yes. The BEST 6K Series single dummy trim is a Grade 2 non-keyed cylindrical knob in dummy function, rated medium duty. The Bravura Biloxi is also a Grade 2 dummy knobset. All three land in the same Grade 2 dummy category as the BA40, which is BHMA/ANSI A156.2 series 4000 Grade 2. The differences are in the knob styling and the series each belongs to - BA40 is Barrington BA trim, the BEST is 6K Series, the Bravura is the Biloxi design.
14) We need a higher grade knob than the Cal-Royal BA40 for a high-traffic opening - what is the step up?
The BA40 is Grade 2. For Grade 1 in a cylindrical knob, the Schlage D10S is a Grade 1 heavy duty non-keyed passage knob with the Orbit knob, and the Falcon X101 is a Grade 1 heavy duty cylindrical passage knobset with an interchangeable core that covers 1-3/8 inch to 2-1/4 inch doors. The Corbin Russwin CK4310 is a Grade 1 passage/closet cylindrical knob covering 1-3/8 inch to 2 inch. Note that all three are passage function - they operate a latch, where the BA40 is fixed dummy trim.
15) The opening needs privacy for a restroom or bedroom - is the Cal-Royal BA40 the wrong part?
Yes, for that use. The BA40 has no locking mechanism - it is single dummy trim. For privacy function in a knob, the Dexter C2000 privacy is Grade 2 and covers 1-3/8 inch to 1-3/4 inch doors, the same thickness range the BA40 covers. The Pamex FTF privacy Baron knob is Grade 3 on that same range. Baldwin Estate 5077 Bethpage and the Deltana 6112 St. Thomas are privacy knobs on the decorative side, the Deltana covering 1-3/8 inch to 2 inch doors.
16) Is a Sargent 78-2875 outside knob or an Imperial ED-BKL580 knob trim the same idea as a Cal-Royal BA40 dummy knob?
No - those are exit device trim, not door-mounted dummy trim. The Sargent 78-2875 is an outside knob for the 7800 Series exit device, and the Imperial ED-BKL580 is storeroom function knob trim for the ED-500 Series device; both mount to a panic device rather than into a bored door prep. The Cal-Royal BA40 is a cylindrical dummy knob that installs into a standard 2-1/8 inch cross bore with a 1 inch edge bore. Similarly, the Sargent 28C-KNOB is exit device trim with knob and rose for 1-3/4 inch doors. If the door has an exit device on it, the trim parts are the right family; if it has a bored prep, the BA40 is.
17) What finishes does the Cal-Royal BA40 dummy knob come in?
Four finishes: US3 polished brass, US10 satin bronze, US10B antique bronze oiled, and US32D satin stainless steel. US32D is the one that lines up with most commercial openings; the bronze options are for matching existing decorative trim.
18) For a light-duty interior opening, is there a simpler alternative to the Cal-Royal BA40?
If the opening does not need a Grade 2 commercial rating, Grade 3 knobsets cover it. The Pamex FT3 Saturn and the Pamex FTF Baron passage are Grade 3 and fit 1-3/8 inch to 1-3/4 inch doors, the same thickness range the BA40 covers. Callan Canova and Callan Santo are Grade 3 entrance knobsets. The trade-off is the cycle and strength class: the BA40 is built to BHMA/ANSI A156.2 series 4000 Grade 2 with wrought brass, bronze or stainless steel exposed trim for commercial traffic, while the Grade 3 sets are the lighter class.
19) We are replacing knobs across a whole building - what pairs with a Cal-Royal BA40 to cover the working doors in the same look?
Within commercial Grade 2 cylindrical knobs, the pairing runs by function. The BA40 handles the fixed-trim openings with no latch. Corbin Russwin CK4410 covers passage/closet at Grade 2 on the same 1-3/8 inch to 1-3/4 inch door range, Dexter C2000 covers passage, privacy, entry/office and classroom all at Grade 2 on that same range, and Sargent 6G04 covers storeroom at Grade 2. Arrow MK01 and RK01 are Grade 2 non-keyed passage knobs on the same 1-3/8 inch to 1-3/4 inch range, differing in that the RK01 uses a ball knob. Knob shape and finish will differ across brands, so a single-brand run is what keeps the look uniform.
