Cal-Royal CAL03-26D – Frequently Asked Questions

1) How does the Cal-Royal CAL03 classroom function actually work at the door?
The CAL03 is an ANSI F84 classroom function. The dead locking latch bolt retracts from either lever until a key is used on the outside to lock the outside lever. Once locked, the inside lever still retracts the latch, so the room can always be exited, and the outside stays locked until the key returns it. There is no inside button or thumbturn, which is the point for classrooms: only a keyholder can lock or unlock the corridor side.
2) Can I key the Cal-Royal CAL03 into my existing Schlage or Corbin Russwin master key system?
In most cases yes. The CAL03 comes with a 6 pin solid brass "C" keyway as standard and the cylinder is compatible with Schlage E and C-K, Russwin D1-2-3-4, Corbin 59/60, Corbin Russwin L4, Sargent LA-LB-LC, Falcon/Weiser E, Arrow A, Yale 8 and GA, and Kwikset. It also takes Medeco, Assa, Kaba and Cal-Royal HSK high security cylinders if the building is on a restricted system.
3) Is the CAL03 rated well enough for a school corridor or a high traffic hospital door?
It is built for that traffic. The CAL03 is an extra heavy duty cylindrical lockset meeting or exceeding BHMA/ANSI A156.2 Series 4000, Grade 1, the top grade for bored locks, and it is a commercial-duty product. The latch bolt is solid brass and UL Listed, exposed trim is wrought brass, bronze or stainless steel, and the levers are zinc casting plated to match the trim. It is also ADA compliant and meets the Buy American Act, which matters on public school and municipal work.
4) I need an office or entry function instead of classroom. What should I look at?
The CAL03 is classroom only, locked and unlocked by key from outside with no inside button, so it is the wrong pick if staff need to lock up from inside the room. For entry/office function in Grade 1 cylindrical, look at the Falcon K501, a Grade 1 entrance lock with push-turnbutton for 1-3/8 to 2-1/4 inch doors, or the TownSteel CE/CEI-109 in extra heavy duty non-clutched. TownSteel also lists the CEC/CECI-109 clutched extra heavy duty and the CDC-109 clutched entry/office if you want a clutched lever that spins free under force.
5) Will the Cal-Royal CAL03 fit a 2-1/4 inch thick door?
No. The CAL03 covers doors from 1-3/8 inch to 2 inch thick. For a door up to 2-1/4 inch, the Falcon K501 Grade 1 cylindrical lock is rated for a 1-3/8 inch to 2-1/4 inch door thickness range, though it is an entrance function rather than classroom.
6) What should I use instead of the Cal-Royal CAL03 on a behavioral health or ligature-resistant opening?
The CAL03 uses a standard lever trim on a 1-3/8 inch to 2 inch door. For a ligature-resistant opening, the TownSteel CRX-A-41 is a Grade 1 heavy duty stainless steel cylindrical lockset with ligature resistant arch trim, built for a 1-3/4 inch door. Note it is a single dummy function with no latch or keying, so it suits push/pull openings rather than a keyed classroom door.
7) What is the alternative to the Cal-Royal CAL03 if the door needs to be released remotely or tied into access control?
The CAL03 is a mechanical classroom lock operated by key and lever only. For an opening that must unlock from a remote station or integrate with an access control system, the BEST 9KW Series is a heavy duty electromechanical cylindrical lock with remote control operation. That path adds power and wiring to the opening, which the mechanical CAL03 does not require.
8) Does the CAL03 latch faceplate work on a beveled door edge?
Yes. The latch faceplate measures 2-1/4 x 1-1/8 inches and is adjustable for flat or beveled doors at 1/8 inch in 2 inches, which is the standard commercial edge bevel. That is the faceplate supplied for the 2-3/4 inch backset; a 2-1/4 x 1-1/8 inch faceplate is the option for the 2-3/8 inch backset.
9) Does the Cal-Royal CAL03 take an interchangeable core?
Yes, as an IC version. Prefix the part number with "IC" and the lock accepts compatible 6 or 7 pin cores from BEST, Falcon and Arrow. It can be supplied combinated or uncombinated, and temporary construction cores plus factory keying are available, which is how most new-construction jobs run it before turning the building over to the owner's permanent cores.
10) Do I need to order a separate left hand or right hand version of the CAL03?
No. The latch bolt is reversible for right hand or left hand doors, so one lock covers either swing and you can field-reverse it on site rather than stocking handed parts across a building.
11) Can the CAL03 be locked down remotely for a lockdown plan?
No. The CAL03 is a mechanical keyed cylindrical lock, single cylinder, with no electrified option in its specification. If your lockdown procedure requires remote locking rather than a teacher stepping into the corridor with a key, the BEST 9KW Series is a heavy duty electromechanical cylindrical lock with remote control operation.
12) How does the TownSteel CE/CEI-109 compare to the Cal-Royal CAL03?
Both are Grade 1 extra heavy duty non-clutched cylindrical locksets. The CAL03 is a classroom function with a keyed single cylinder, a 1/2 inch throw latch and a 2-3/4 inch standard backset. The TownSteel CE/CEI-109 is an entry/office function in the CE Series. The choice comes down to whether the door must be locked from the outside by key alone, which is the classroom function, or from the inside by the occupant.
13) Can the TownSteel CRX-A-41 be used as a drop-in replacement for a Cal-Royal CAL03?
No. The CAL03 is a keyed classroom lockset with a latch and a 2-3/4 inch backset. The TownSteel CRX-A-41 is a single dummy trim, meaning it has no latch and no keying, so it cannot secure or latch the door. It looks similar on a cylindrical prep but serves an inactive leaf or a pull-side application only.
14) What finish does the Cal-Royal CAL03 come in?
26D Satin Chrome, which is the usual institutional finish and the easiest to match against existing exit devices, closers and hinges in schools and offices. The levers are zinc casting plated to match the exposed trim, so the trim and lever read the same on the door.
