Cal-Royal CAL07-26D – Frequently Asked Questions

1) Will the Cal-Royal CAL07 classroom intruder lock fit a 1-3/4 inch door?
Yes. The CAL07 covers doors from 1-3/8 to 2 inches thick, so a standard 1-3/4 inch commercial door is right in the middle of the range. That same range also takes older 1-3/8 inch interior doors and heavier 2 inch slabs without a separate part number, so a school or office with mixed door thicknesses can standardize on one lock.
2) What does the classroom intruder function on the Cal-Royal CAL07 actually do in a lockdown?
The CAL07 is an ANSI F110 classroom intruder lock, which means the teacher locks the door from inside the room with a key rather than stepping into the hallway. The outside lever is locked and unlocked by key from either side; the inside lever never locks, so anyone inside can always turn the lever and get out. The latch bolt retracts from the inside lever at all times, and from the outside lever only when it isn't locked.
3) Is the Cal-Royal CAL07 heavy duty enough for a school corridor door?
It's built to BHMA/ANSI A156.2 Series 4000, Grade 1, which is the top commercial grade and the one written into most school and institutional specs for high traffic openings. Exposed trim is wrought brass, bronze or stainless steel with zinc casting levers plated to match, and the latch bolt is solid brass and UL Listed.
4) What backset do I need to order for a Cal-Royal CAL07, and will it hit my existing cross bore?
Two backsets are orderable: 2-3/8 inch and 2-3/4 inch. Measure from the door edge to the center of the existing bore. 2-3/4 inch is the standard on the CAL07 and the usual commercial backset; 2-3/8 inch is the common residential and light commercial one. Pick the one that matches the hole you already have, because the backset is a required selection on the order.
5) Can I key the Cal-Royal CAL07 into my building's existing key system?
Most likely. It ships with a 6-pin solid brass C keyway as standard, and the cylinder is available to match 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. Medeco, Assa, Kaba and Cal-Royal HSK high security cylinders are also available, so a facility already on a restricted system can stay on it.
6) Does the Cal-Royal CAL07 take an interchangeable core?
Yes. An IC version accepts 6 or 7 pin cores from BEST, Falcon and Arrow, ordered by putting the IC prefix in front of the part number. It comes combinated or uncombinated, with factory keying, control key and master key options. If your maintenance staff already rekeys openings by pulling cores with a control key, order the IC version and keep that workflow.
7) What is the closest Grade 1 cylindrical lock to the Cal-Royal CAL07 if the opening needs an entrance function instead of classroom intruder?
The Cal-Royal CAL07 is a Grade 1 cylindrical lockset built for the classroom intruder function, where the outside lever is locked and unlocked by key from either side and the inside lever cannot be locked. For an opening that needs a straight entrance function instead, the Falcon K501 is a Grade 1 heavy duty entrance cylindrical lock with a push-turnbutton, and the TownSteel CE/CEI-109 is a Grade 1 extra heavy duty non-clutched cylindrical lockset in the entrance/office function. All three are Grade 1 cylindrical locks; the difference is how the outside lever is secured - by key from either side on the CAL07, by turnbutton on the K501.
8) Which Grade 1 cylindrical lockset should be used on a fire-rated opening instead of the Cal-Royal CAL07?
The Falcon K501 carries a fire rating in a Grade 1 heavy duty cylindrical entrance lock. The Cal-Royal CAL07 has a UL Listed latch bolt and offers a 2-3/4 inch anti-friction latch with 3/4 inch throw for pairs of fire doors as a backset option, so the two differ in how the fire-door application is addressed - a rated lockset on the K501 side, an anti-friction latch option on the CAL07 side.
9) Is the TownSteel CRX-A-41 a substitute for the Cal-Royal CAL07?
No. The TownSteel CRX-A-41 is a single dummy trim - it has no latch and no cylinder, so it does not secure or latch an opening. The Cal-Royal CAL07 is a keyed single cylinder classroom intruder lockset with a 1/2 inch throw solid brass latch bolt. The CRX-A-41 also fits only a 1-3/4 inch door, while the CAL07 covers 1-3/8 inch to 2 inch. The CRX-A-41 suits the inactive leaf of a pair; it is not an alternative on a door that must lock.
10) What replaces the Cal-Royal CAL07 when the classroom needs to be locked and unlocked remotely?
The BEST 9KW Series is a heavy duty electromechanical cylindrical lock with remote control operation, which allows the opening to be secured from a location other than the door. The Cal-Royal CAL07 is mechanical: the outside lever is locked and unlocked by turning the key from either side, and the inside lever cannot be locked. Choose on whether the facility wants a keyed action at the door or a remote release.
11) Will the Cal-Royal CAL07 latch work on a beveled door edge?
Yes. The latch faceplate measures 2-1/4 x 1-1/8 inches and adjusts for either a flat or a beveled door at 1/8 inch in 2 inches, which is the standard bevel, so the same latch handles both without a separate part. That faceplate is for the 2-3/4 inch backset; a 2-1/4 x 1-1/8 inch faceplate is offered for the 2-3/8 inch backset.
12) Is the Cal-Royal CAL07 latch reversible, or do I have to specify handing?
Handing isn't a separate order line here. The solid brass latch bolt is reversible for right hand or left hand, so one lock covers either swing and you can carry a single part number as spare stock across a building.
13) Will the Cal-Royal CAL07 latch engage a worn or slightly out of alignment strike?
The standard latch bolt throws 1/2 inch, which is normal for a cylindrical lockset and expects a reasonably aligned frame. For a pair of fire doors there's a 2-3/4 inch anti-friction latch option with a 3/4 inch throw, which reaches deeper. If your frame has settled or the door has sagged, plan on adjusting the strike rather than counting on extra throw.
14) What backset options besides 2-3/4 inch does the Cal-Royal CAL07 offer for wide stile or unusual doors?
Beyond the 2-3/4 inch standard, extended backsets of 3-3/4 inch and 5 inch are offered, along with 2-1/8 inch. Those long backsets are what you need when the lock has to sit farther in from the door edge, and they let the CAL07 go on openings a standard 2-3/8 or 2-3/4 inch bored lock can't reach.
15) What are the alternatives to the Cal-Royal CAL07 if I need a thicker door, remote lockdown, or a clutched lever?
Three directions. For doors thicker than 2 inches, the Falcon K501 covers 1-3/8 to 2-1/4 inch and is Grade 1 heavy duty. For centralized lockdown instead of key-in-the-door, the BEST 9KW Series is a heavy duty electromechanical cylindrical lock with remote control operation. If vandalism is the concern, the TownSteel CEC/CECI-109 and CDC-109 are clutched Grade 1 locksets, where forcing a locked lever spins it free instead of loading the internal parts.
16) Can I put the Cal-Royal CAL07 on a pair of fire doors?
There's a specific option for it: a 2-3/4 inch anti-friction latch with a 3/4 inch throw intended for pairs of fire doors. The anti-friction feature keeps the latch from dragging as the doors close under a coordinator, and the deeper throw reaches into the strike on the inactive leaf. Specify that latch option rather than the standard 1/2 inch throw latch for a pair.
17) What is the difference between the Cal-Royal CAL07 and a clutched cylindrical lockset like the TownSteel CDC-109 or CEC-109?
The TownSteel CDC-109 is a Grade 1 heavy duty clutched cylindrical lockset and the CEC/CECI-109 is a Grade 1 clutched extra heavy duty cylindrical lockset, both in the entrance/office function; a clutched lever spins free when locked so force on the lever is not carried into the lock. The TownSteel CE/CEI-109 is the non-clutched counterpart in the same entrance/office function. The Cal-Royal CAL07 is a classroom intruder function lockset with zinc casting levers plated to match wrought brass, bronze, or stainless steel trim, keyed from either side to lock and unlock the outside lever.
18) For standardizing a school on Grade 1 cylindrical hardware, how do the Cal-Royal CAL07 and the TownSteel CE, CEC, and CDC 109 locksets line up?
All four are Grade 1 cylindrical locksets. The Cal-Royal CAL07 covers the classroom intruder function and takes a 6-pin solid brass C keyway standard, with interchangeable core options accepting 6 or 7 pin cores from BEST, FALCON, and ARROW. The TownSteel CDC-109, CE/CEI-109, and CEC/CECI-109 all carry the entrance/office function, in clutched heavy duty, non-clutched extra heavy duty, and clutched extra heavy duty builds respectively. A facility can hold Grade 1 across the openings and select the function door by door.
19) What finishes does the Cal-Royal CAL07 Calypso Series lock come in, and can I match existing hardware?
Six finishes: US3 polished brass, US4 satin brass, US10 satin bronze, US10B antique bronze oiled, US26 polished chrome and 26D satin chrome. The levers are zinc castings plated to match the trim finish, so the lever and rose read as one finish across an opening. US26D satin chrome and US4 satin brass are the two you'll most often be matching in a school or office already standardized on Grade 1 hardware.
