Cal-Royal CAL04-26D – Frequently Asked Questions

1) What is a communicating lock, and when would I use the Cal-Royal CAL04 instead of a regular entry lever?
A communicating function lock is for a door between two adjoining rooms where each side needs its own control. On the CAL04, the lever retracts the latch from either side, and turning the key in either lever locks or unlocks only that lever, independently of the other. That's the difference from an entry or office lock, where one side controls the other. Typical use is connecting hotel rooms, adjoining apartments, or paired offices where either occupant can shut off access from their side without affecting the neighbor.
2) Will the Cal-Royal CAL04 fit a 1-3/8 inch door, and what about a thicker 2 inch door?
Both work. The CAL04 leverset is built for doors 1-3/8 inches through 2 inches thick, so it covers the older 1-3/8 inch interior door as well as the standard 1-3/4 inch commercial door and heavier 2 inch slabs. That range is wider than a lot of Grade 1 cylindrical locks, which start at 1-3/4 inches.
3) What backset do I need to order for the Cal-Royal CAL04 communicating lock?
Backset is a required choice at order: 2-3/8 inch or 2-3/4 inch. 2-3/4 inch is the standard on this lock and the one the standard 2-1/4 x 1-1/8 inch faceplate is set up for; a matching 2-1/4 x 1-1/8 inch faceplate is used for the 2-3/8 inch backset. Measure from the door edge to the center of the existing bore before you pick, since the two are not interchangeable once the door is prepped.
4) Is the Cal-Royal CAL04 handed, or is the latch reversible for a left hand door?
No handing to specify. The solid brass latch bolt is reversible for right hand or left hand applications, and the faceplate adjusts for flat or beveled doors at 1/8 inch in 2 inches. That means one part number covers either swing, which is worth knowing if you're stocking spares across a building.
5) Can the Cal-Royal CAL04 be keyed into my existing Schlage or Corbin master key system?
Yes, on a long list of systems. The lock ships with a 6 pin solid brass "C" keyway as standard and is compatible with Schlage E, Schlage C-K, Russwin D1-2-3-4, Corbin 59/60, Corbin-Russwin L4, Sargent LA-LB-LC, Falcon/Weiser E, Arrow A, Yale 8, Yale GA, and Kwikset. It also accepts Medeco, Assa, Kaba, and Cal-Royal HSK high security cylinders if the facility is on a restricted key system.
6) Is the Cal-Royal CAL04 Grade 1 and UL Listed for a commercial building?
Grade 1 under BHMA/ANSI A156.2 Series 4000, UL Listed, ADA compliant, and it meets the Buy American Act. The ANSI function code is F80. Those are the values a spec writer or a government purchaser needs to match the hardware schedule, and the Buy American line matters on federal and municipal jobs.
7) My door is 2 inches thick. Which lever locks actually cover that, and which ones will not?
At a full 2 inches your options narrow fast. The Cal-Royal CAL04 is rated to 2 inches, and so is the Falcon K101 passage lock at 1-3/8 to 2-1/4 inches, plus the Hager 2510, 2525, 2540 and 2580 Grade 2 levers at 1-3/8 to 2 inches, and the Deltana Manchester, Morant and Linstead entry levers at 1-3/8 to 2 inches. What will not reach: the Dexter C1000 classroom and entry versions stop at 1-3/4 inches, the Design Hardware J75 and X75 are listed at 1-3/4 inches only, and the Kwikset Breton sets top out at 1-3/4 inches.
8) What is the closest Grade 1 cylindrical lever lock to the Cal-Royal CAL04 when the opening needs a keyed function other than communicating?
The Cal-Royal CAL04 is a Grade 1 communicating lock, where the key in either lever locks or unlocks that lever independently. If the opening instead needs keyed entry from one side, the Dexter C1000 Series Entry/Office lever is Grade 1 with an Entrance/Office function and a 1-3/8 inch to 1-3/4 inch door thickness range, and the Dexter C1000 Series Classroom lever is Grade 1 classroom function over the same 1-3/8 inch to 1-3/4 inch range. Both are keyed clutching cylindrical levers, so they cover a keyed commercial opening, but neither gives the two-sided independent locking the CAL04 provides.
9) What Grade 1 lever lock fits a door thicker than 2 inches if the CAL04 will not?
The Cal-Royal CAL04 covers doors 1-3/8 inch to 2 inch thick. For a thicker leaf, the Falcon K101 is a Grade 1 heavy duty cylindrical lock with a 1-3/8 inch to 2-1/4 inch door thickness range and a fire rating. The K101 is a passage function with non-handed levers, so it is not keyed and does not provide the independent two-sided locking of the CAL04 - it is the choice when the leaf is out of range and the opening only needs latching.
10) What should I use instead of the Cal-Royal CAL04 on an institutional or patient room door?
The CAL04 is a communicating lock, keyed on both sides with each lever locking independently. For an asylum or institutional opening where both sides are keyed with no free egress from either lever, the Dexter C1000 Series Asylum (F87) is Grade 1 and fits doors 1-3/8 inch to 2 inch, the same thickness range as the CAL04. The Arrow MK33-BD-CS is an Asylum/Institution/Utility function heavy duty lock supplied with a Schlage C keyway on a ball knob rather than a lever.
11) Can a privacy lever be used in place of the Cal-Royal CAL04 between two adjoining rooms?
They do different jobs. The CAL04 is keyed on both sides, so occupants of each room control access with a key and each lever locks independently. A privacy lever such as the Arrow MK02-TA, a fire rated Privacy/Bed/Bath lock for doors 1-3/4 inch to 2 inch, or the Hager 2540 Grade 2 privacy lock for doors 1-3/8 inch to 2 inch, locks from one side by thumbturn or button with no key control. Where each room needs its own key control over the connecting door, the privacy function does not substitute.
12) Does the Cal-Royal CAL04 come in a small format interchangeable core version?
An interchangeable core version is offered, ordered by putting the prefix "IC" before the part number. Those locks take 6 or 7 pin cores from BEST, FALCON, and ARROW, and can be supplied combinated or uncombinated, with temporary construction cores and factory keying available. If your campus is already on a BEST core system, that's the version to specify so your existing cores drop straight in.
13) What is the Cal-Royal CAL04 made of, and will it hold up in a high traffic hallway?
Exposed trim is wrought brass, bronze, or stainless steel depending on finish, with zinc casting levers plated to match the trim. The latch bolt is solid brass and dead locking. That construction plus the Grade 1 A156.2 rating is what puts it in schools, hospitals, and hotel corridors rather than light residential use; it's classified commercial, not residential.
14) I need a lock for a pair of fire doors, not adjoining rooms. Is the CAL04 still the right choice?
For a pair of fire doors, the latch matters more than the lock body. The Calypso line offers a 2-3/4 inch anti-friction latch with a 3/4 inch throw specifically for pairs of fire doors, which is a deeper throw than the standard 1/2 inch latch this lock ships with. Specify that latch option if the opening is a fire rated pair. If the door is a single leaf between two rooms, the standard 1/2 inch latch and communicating function is what you want.
15) What Grade 1 lever locks can I use on the other doors so the whole suite matches the CAL04?
The CAL04 covers only the communicating door, so the rest of the openings need their own functions. Grade 1 cylindrical levers we carry alongside it include the Dexter C1000 Series in Entry/Office, Classroom, Classroom Security, and Asylum functions, the Falcon K101 passage (Grade 1, heavy duty, fire rated, 1-3/8 to 2-1/4 inch doors), the Corbin Russwin CL3110 vandal resistant passage, and the BEST 9K Series 1DT single dummy trim. Watch door thickness when you mix: the Dexter classroom and entry versions are listed for 1-3/8 to 1-3/4 inch, narrower than the CAL04's 1-3/8 to 2 inch range.
16) Can I use a keypad or keyless lever instead of a keyed communicating lock?
You can go keyless, but the function changes. Keypad and pushbutton lever sets we carry include the Lockey 1150 and 1150S (1-1/8 to 2 inch doors), the Lockey 2835 and 2835DC double combination (1 3/16 to 2 inch doors), the Delaney LP250 Grade 2 electronic keypad, and the Emtek Classic keypad leverset. All of those are code-entry passage type locks, not communicating locks, so neither side gets independent key control of its own lever the way the CAL04 gives you. Pick keyless when you want to drop keys entirely on a single-direction opening, not when you need two-sided independent locking.
17) Is there a Grade 2 alternative to the Cal-Royal CAL04 for a lighter-traffic opening?
The CAL04 is built to ANSI/BHMA Grade 1 for commercial use. Where a lighter-duty commercial lever is acceptable, the Hager 2525 is a Grade 2 cylindrical entry lock covering doors 1-3/8 inch to 2 inch - the same thickness range as the CAL04 - and the Hager 2580 is a Grade 2 storeroom lock over that same range. Both are single-function keyed levers rather than communicating locks, so each side cannot be keyed independently.
18) I need a non-keyed lever on the adjoining door - what pairs with the Cal-Royal CAL04?
The CAL04 is keyed with a single cylinder function on each lever. On the doors in the same run that only need latching, the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage/closet lever that is fire rated for doors 1-3/4 inch to 2 inch, and the Design Hardware X75 is a Grade 1 passage lever lockset for 1-3/4 inch doors. Both are non-keyed, so they latch and release from either side without a cylinder.
19) What is a keyless alternative to the Cal-Royal CAL04 for a connecting door where keys are hard to manage?
The CAL04 uses a 6 pin solid brass C keyway cylinder in each lever. If the goal is to drop keys entirely, 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 doors 1-1/8 inch to 2 inch with an adjustable backset. These are code-entry from one side rather than two independently keyed levers, so each room does not get separate key control.
20) Will a residential Grade 3 lever work where the Cal-Royal CAL04 is specified?
The CAL04 is a Grade 1 commercial lockset. Grade 3 levers such as the Kwikset 200BRNL Breton passage lever for doors 1-3/8 inch to 1-3/4 inch, the Kwikset 300BRNL Breton privacy lever over the same range, or the Callan Artino Grade 3 entrance leverset are built to a lighter residential duty rating and cover a narrower door thickness range than the CAL04's 1-3/8 inch to 2 inch. Where a drawing calls out ANSI/BHMA Grade 1, a Grade 3 lever will not satisfy it.
21) Which lever lock takes interchangeable cores like the Cal-Royal CAL04 does?
CAL04 interchangeable core versions accept 6 or 7 pin cores from BEST, Falcon and Arrow. Among comparable heavy duty levers, the BEST 9K Series is a Grade 1 heavy duty cylindrical lever line, though the 1DT single dummy trim is non-keyed and takes no core. The BEST 7KC Series single dummy trim is Grade 2 medium duty and likewise non-keyed. If the facility is standardizing on a BEST small format core, the CAL04 IC version accepts that core on the connecting door itself.
22) What do I use on the same opening if the door needs an access control release rather than a key?
The CAL04 is a mechanical communicating lock keyed on both levers. Where the connecting door has to release from a card reader or building system, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever running on 12VAC/DC for doors 1-3/4 inch to 2 inch, available in a keyed version as well. Fail safe means the lever unlocks on loss of power, which is a different security behavior than the CAL04's mechanical key control from each side.
23) Is a dummy lever a substitute for the Cal-Royal CAL04 on a connecting door?
No. A dummy trim such as the Accentra 455LN Augusta, a Grade 1 single dummy cylindrical lever in the 5400 Series, or the Callan Bentley Grade 2 dummy lever, is a fixed pull with no latch and no locking. The CAL04 has a 1/2 inch throw dead locking latch bolt and is keyed on both sides. Dummy trim belongs on an inactive leaf, not on a door that has to latch or lock between two rooms.
24) What finishes does the Cal-Royal CAL04 lever come in to match the rest of my building?
Six finishes: US3 polished brass, US4 satin brass, US10 satin bronze, US10B antique bronze oiled, US26 polished chrome, and 26D satin chrome. Satin chrome (26D) is the usual match for commercial openings already running brushed hardware, and the levers are plated to match the trim so the set reads as one piece.
