Cal-Royal CSL00-26D – Frequently Asked Questions

1) Will the Cal-Royal CSL00 lever lock fit a 1-3/8 inch door, or do I need a 1-3/4 inch door?
Both work. The CSL00 Entrance/Office lever lock covers 1-3/8 inch through 1-3/4 inch doors, so it goes on older interior openings and standard commercial doors without a different part number. It bores to a 2-3/4 inch backset, the usual commercial backset, so it drops into an existing commercial prep. If your doors run thicker than 1-3/4 inches, this is not the lock for that opening.
2) Will the Cal-Royal CSL00 latch into the strike that's already in my frame?
It depends on what strike is in the frame now. The CSL00 ships with an ANSI strike measuring 1-1/4 inches x 4-7/8 inches with a 1-1/4 inch lip and square corners, and the latchbolt has a 1/2 inch throw. If your frame is prepped for a standard ANSI strike cutout, the supplied strike drops straight in. If you have a T strike or a full lip strike in the frame, those are available on request instead of the ASA strike, so specify it with the order rather than reworking the frame.
3) How does the Entrance/Office function on the Cal-Royal CSL00 actually lock and unlock?
It's ANSI F109 turn/push button locking. Push and turn the button on the inside lever and the outside lever locks, and it stays locked until someone releases the button by hand. A key retracts the latch from outside while it's locked. This is the function you want on a tenant suite door or a private office where staff lock up on the way out and the outside stays locked all day. It is not a classroom function and it does not unlock automatically when the inside lever is turned.
4) Do I have to order the Cal-Royal CSL00 handed for a left hand or right hand door?
No handing to specify. The solid brass latchbolt is reversible in the field for right hand or left hand openings, so one part number covers either swing. That matters if you're stocking spares for a building with doors swinging both ways, because you carry one lock instead of two.
5) Is the Cal-Royal CSL00 heavy duty enough for a busy commercial corridor, or should I step up to a Grade 1 lock?
The CSL00 is ANSI/BHMA A156.2 Series 4000 Grade 2 and exceeds 400,000 cycles, which covers offices, multi-tenant residential, hotels, and retail traffic. Grade 2 is the commercial medium-duty tier; Grade 1 is the heavy-duty tier. If the opening is an entrance getting constant abuse and the spec calls for Grade 1 in the same Entry/Office function, the Dexter C1000 Series Entry/Office cylindrical lever is the Grade 1 equivalent and covers the same 1-3/8 to 1-3/4 inch door range.
6) What is the closest equivalent to a Cal-Royal CSL00 entrance/office lever lock from another brand?
The Falcon B511CP6D is the nearest match in function and grade: it is a Grade 2 cylindrical lever lock with Entry/Office function, the same Grade 2 rating and Entrance/Office function the CSL00 carries. The Falcon is catalogued as medium duty. Both are lever-trim cylindrical locks for the same keyed office opening, where the inside button locks the outside lever until a key or manual release restores it.
7) I need a heavier lock than a Grade 2 entrance/office lever for a high-traffic entry. What steps up?
The Dexter C1000 Series Entry/Office lever lock is Grade 1 with clutching lever trim and a 1-3/8 inch to 2 inch door thickness range, against the Cal-Royal CSL00's Grade 2 rating and 1-3/8 inch to 1-3/4 inch door range. Function is the same Entrance/Office on both, so the opening behaves identically for the tenant; the difference is the ANSI/BHMA grade and the extra door thickness the Dexter covers.
8) The door does not need to lock at all - what do I use instead of a keyed entrance lever?
For an opening that only needs latching, a passage lever is the right part rather than the keyed Cal-Royal CSL00. The Falcon B101 is a Grade 2 cylindrical passage lever lock with non-handed levers, and the Hager 2510 is a Grade 2 passage cylindrical lever lock covering 1-3/8 inch to 2 inch doors. Both hold the same Grade 2 rating as the CSL00 but carry no cylinder, so the corridor side always opens.
9) The opening must stay locked to the outside at all times with the inside always free. Is an entrance/office lock right?
No - an entrance/office lock like the Cal-Royal CSL00 relies on someone setting the inside button, so it can be left unlocked. A storeroom function keeps the outside lever locked permanently and is keyed every time. The Hager 2580 is a Grade 2 storeroom cylindrical lock with a Withnell lever for doors 1-3/8 inch to 2 inch thick, the same Grade 2 level as the CSL00.
10) For a classroom door, can I use the same entrance/office lever I use on the offices?
Classrooms are usually specified on classroom function, not entrance/office. The Cal-Royal CSL00 is Entrance/Office, locked and unlocked by an inside button; the Dexter C1000 Series classroom lever lock is Grade 1 with clutching lever trim and classroom function, keyed from the outside so the room cannot be left unsecured by the button, and Dexter also lists a Classroom Security version of the C1000 in Grade 1. Both Dexter versions cover 1-3/8 inch to 1-3/4 inch doors, the same range as the CSL00.
11) Is a knob-style turn-button entrance lock the same thing as an entrance/office lever lock?
The locking behavior is the same but the trim is not. The Arrow HK11-BB is a turn-pushbutton entrance cylindrical lock with a ball knob and a conventional cylinder, Grade 2, for 1-3/8 inch to 1-3/4 inch doors - the same door range and grade as the Cal-Royal CSL00. The CSL00 uses lever trim and is built for barrier-free ADA application, which a ball knob does not satisfy.
12) What is the CLUTCH system on the Cal-Royal Pioneer SL locks and does it help with vandalism?
When the outside lever is locked, the clutch lets it spin free instead of resisting. Someone hanging on the handle or forcing it turns the lever through open air, so the force never reaches the spindle or the latch retractor. That's the failure mode on abused entrance doors, a snapped or sagging lever. The CSL00 also carries an independent spring on each side, so the levers don't droop over time, which is the other common maintenance call on lever hardware.
13) What keyway does the Cal-Royal CSL00 use and can it be keyed into my building's master system?
The CSL00 is a single cylinder keyed lock with a 6-pin "c" keyway and ships with 2 keys per lock. Cal-Royal keys them per individual job requirement, so tell us the keying at order time rather than trying to sort it in the field. If your building runs a Schlage C system and you're mixing brands, note that a Schlage C keyway lock like the Arrow MK33-BD-CS is a different family of hardware, so plan the keying across both when you spec.
14) Does the Cal-Royal CSL00 meet ADA lever requirements for a barrier-free opening?
Yes. The CSL00 is stated to meet ADA requirements and is specifically built for barrier-free application, which is why it's a lever and not a knob. On a healthcare, school, or public building opening where the code officer is checking operable hardware, that's the box this ticks.
15) Can the Cal-Royal CSL00 be installed on a beveled door edge, and can I thru-bolt it?
Both are handled. The front measures 2-1/4 inches x 1-1/8 inches and adjusts for flat or beveled doors at 1/8 inch in 2 inches, the standard commercial bevel, so you're not shimming a beveled edge. Thru-bolt mounting is an option if you want the roses pulled tight through the door on a high-abuse opening rather than screwed to the mounting plate alone.
16) I need a passage or privacy lever to match the Cal-Royal CSL00 on the other doors in the suite. What do I order?
The CSL00 is only the keyed Entrance/Office function, so the closet and restroom doors need different hardware. Within the same commercial Grade 2 tier, the Falcon B101 covers passage/hall/closet and the Hager 2540 covers the non-keyed openings in a 1-3/8 to 2 inch door range. Understand that these are different brands, so the levers will not visually match the Cal-Royal trim. If matching appearance across every door matters more than mixing brands, spec the whole suite from one manufacturer's series.
17) Is there a cheaper residential-grade alternative to the Cal-Royal CSL00, and when is that a mistake?
Grade 3 entrance leversets exist, like the Callan Artino or the Master Lock RL Series keyed entry lever, and they'll work on a light-use door. On a commercial opening they're the wrong call: the CSL00 is a Grade 2 commercial lock exceeding 400,000 cycles, and Grade 3 is the residential tier well below that. For an apartment interior or a low-traffic back office the Grade 3 lever is defensible. For a tenant entrance, a school, or anything a code inspector reads as commercial, stay at Grade 2 or above.
18) I want keyless entry on this door instead of a key. What replaces the Cal-Royal CSL00?
The CSL00 is a mechanical keyed lock, so if you're going keyless you're changing product type, not ordering an option. A mechanical pushbutton lever like the Lockey 2835, which fits 1-3/16 inch to 2 inch doors, or the Lockey 1150 at 1-1/8 inch to 2 inch, gets you code entry with no wiring. For an electronic keypad, the Delaney LP250 is a Grade 2 keypad leverlock. Any of those changes your door prep, so check the prep before you swap.
19) Will a Hager 2525 work in place of a Cal-Royal CSL00?
The Hager 2525 is a Grade 2 commercial cylindrical entry lock with a lever handle, matching the Cal-Royal CSL00's Grade 2 rating and lever trim. Its door thickness range runs 1-3/8 inch to 2 inch where the CSL00 covers 1-3/8 inch to 1-3/4 inch. Hager lists the 2525 function as Entrance; the CSL00 is Entrance/Office with turn/push button locking, so confirm the button-locking behavior matches what the opening needs before swapping.
20) Can I put a residential-grade entry lever on a commercial office door instead?
The Cal-Royal CSL00 is rated Grade 2 and specified for commercial use. Residential-line entry levers sit a grade below: the Master Lock BC Series return-style keyed entry lockset and the Callan Artino entrance leverset are both Grade 3 entrance function. They latch and key the same way, but a Grade 3 lever is a different durability class from the Grade 2 CSL00 for a commercial opening.
21) I want to get rid of keys on an office door. What replaces an entrance/office cylindrical lever lock?
A keyless lever lock removes the cylinder entirely. The Delaney LP250 is a Grade 2 electronic keypad leverlock, the same Grade 2 level as the Cal-Royal CSL00, and Lockey offers mechanical pushbutton lever locks such as the 2835 for doors 1 3/16 inch to 2 inch thick and the 1150 heavy duty keypad lever set for 1-1/8 inch to 2 inch doors. The CSL00 uses a 6-pin keyway cylinder with two keys per lock, so moving to any of these changes how the door is issued and re-coded.
22) A dummy lever is cheaper - can I use one on an office door that gets keyed?
No. A dummy lever has no latch and no cylinder; it is fixed trim for an inactive leaf. The BEST 7KC Series 1DT single dummy trim lever is Grade 2 non-keyed medium duty, and the Accentra 455LN Augusta is a Grade 1 single dummy from the 5400 Series. The Cal-Royal CSL00 is a keyed single-cylinder lock with a latchbolt, which is what an office door that must secure requires.
23) For a restroom or bedroom door, is an entrance/office lock the right function?
No - those openings take privacy function, which locks from inside with no key on the outside. The Hager 2540 privacy cylindrical lock with Withnell lever is Grade 2 for 1-3/8 inch to 2 inch doors, and the Arrow MK02-TA is a privacy cylindrical lock with a Tudor knob and a fire rating. The Cal-Royal CSL00 is a keyed single-cylinder Entrance/Office lock, which is the wrong function for a bath or bedroom.
24) What is the difference between an entrance/office lever and an asylum or utility function lock?
Asylum and institution function is keyed on both sides with no button and no free egress from the inside, used on utility and secure rooms. The Arrow MK33-BD-CS is a Grade 2 asylum cylindrical lock with a ball knob and a Schlage C keyway, and the Dexter C1000 asylum F87 is Grade 1 for 1-3/8 inch to 2 inch doors. The Cal-Royal CSL00 is Entrance/Office with a single cylinder and an inside turn/push button, so the inside always operates freely.
25) What finishes does the Cal-Royal CSL00 come in, and will it match the rest of my building's hardware?
Three finishes: US26D satin chrome, US10B oil-rubbed bronze, and US3 polished brass. US26D is the usual commercial standard, so if your existing corridor hardware is satin chrome that's the match. The exposed trim is wrought brass, bronze, or stainless steel, and the zinc cast levers are plated to match the trim, so the lever and rose read as one finish rather than drifting apart.
