Cal-Royal CSL05 Storeroom Lock with Clutch, Grade 2, Pioneer SL Series

The Cal-Royal CSL05 is a cylindrical lever storeroom lock from the Pioneer SL Series, engineered for reliable daily use in offices, schools, hospitals, apartments, and hotel/motel applications.

Cal-Royal CSL05-26D – Frequently Asked Questions

1) Will the Cal-Royal CSL05 storeroom lock fit a 1-3/8 inch door, or is it only for 1-3/4 inch?
Both. The CSL05 cylindrical lever lock covers 1-3/8 inch through 1-3/4 inch doors, so it works on older interior doors as well as standard commercial 1-3/4 inch openings. It uses a 2-3/4 inch backset, the common commercial backset, so it drops into an existing 161 prep on most commercial doors without redrilling.
2) What does storeroom function actually do on the CSL05 lock, and is it the right function for a supply room?
Storeroom function means the outside lever is always locked and only the key retracts the latch; the inside lever is always free to exit. There is no button or thumbturn to leave it unlocked, so nobody can prop the room open by accident. That is ANSI Function F84, and it is what you want on a storeroom, mechanical room, or electrical closet. If you need staff to be able to leave the door unlocked during the day, use an entrance/office function instead, such as the Hager 2525 Grade 2 entry lock.
3) Does the CSL05 need to be ordered left hand or right hand?
No handing to specify. The solid brass latchbolt is field-reversible for right or left hand doors, so one part covers both swings. That matters if you are buying for a building with mixed swings, since you can stock one lock and set it in the field.
4) Will the CSL05 latch into the strike that's already in my frame?
It ships with an ANSI strike, 1-1/4 inch x 4-7/8 inch with a 1-1/4 inch lip and square corners, and the latchbolt has a 1/2 inch throw. If your frame already has an ANSI 4-7/8 inch strike prep (standard on hollow metal commercial frames), the supplied strike drops straight in. If your existing strike is a small round-corner residential type, use the strike that comes with the lock and expect to enlarge the frame prep.
5) Is a Grade 2 storeroom lock tough enough for a school or apartment corridor?
The CSL05 conforms to ANSI/BHMA A156.2 Series 4000 Grade 2 and exceeds 400,000 test cycles, which covers offices, schools, hospitals, apartments and hotels. Where the traffic is heavier or the door gets abused, a Grade 1 cylindrical is the step up. If your spec sheet calls out Grade 1, this will not meet it, and you should be looking at a Grade 1 cylindrical such as the Dexter C1000 Series, which also covers 1-3/8 inch to 1-3/4 inch doors.
6) What's a direct alternative to the Cal-Royal CSL05 storeroom lock from another brand?
The Hager 2580 with the Withnell lever is the closest match we carry: a Grade 2 cylindrical storeroom lock covering 1-3/8 inch to 2 inch doors, so it takes the same openings as the CSL05 plus thicker ones. If the storeroom door is in a rougher setting and you would rather go up a grade, the Dexter C1000 Series Grade 1 line runs the same 1-3/8 inch to 1-3/4 inch door range, though its keyed offerings are classroom, classroom security, entry/office and asylum functions rather than storeroom.
7) My door is 2 inches thick. Will the CSL05 work?
No. The CSL05 tops out at 1-3/4 inches. For a 2 inch door, look at a lock rated to that thickness, such as the Hager 2580 Grade 2 storeroom lock, which covers 1-3/8 inch to 2 inch. Forcing a lock past its stated thickness range leaves the spindle short and the levers loose.
8) What is the closest Grade 2 storeroom lever lock to the Cal-Royal CSL05?
The Hager 2580 is the nearest match. Both are Grade 2 cylindrical lever locks in the storeroom function, so both hold the outside lever locked at all times with entry by key only. The CSL05 fits doors 1-3/8 inch to 1-3/4 inch thick; the Hager 2580 covers 1-3/8 inch to 2 inch, so on a 2 inch door the Hager is the one that fits. On standard 1-3/4 inch commercial doors either will land in the same prep.
9) I need a keyed lever but staff should be able to leave it unlocked during business hours - what should I order instead of a storeroom lock?
Storeroom function on the Cal-Royal CSL05 keeps the outside lever locked permanently, with no way to leave it in a passage state. For a door that gets unlocked for the day, an entry/office function is the right pick: the Falcon B511CP6D is a Grade 2 cylindrical lever lock with Entrance/Office function, and the Hager 2525 is a Grade 2 cylindrical entry lock for doors 1-3/8 inch to 2 inch thick. Both let the outside lever be set unlocked and then relocked, which storeroom function does not do.
10) The door is 2 inches thick - what keyed lever works there since the Cal-Royal CSL05 tops out at 1-3/4 inch?
The CSL05 is built for doors 1-3/8 inch to 1-3/4 inch. For a 2 inch leaf, the Hager 2580 Grade 2 storeroom lever covers 1-3/8 inch to 2 inch and keeps the same locked-outside-lever behaviour; the Hager 2525 Grade 2 entry lock covers the same range if the door needs to be unlocked during the day. Heavier options at 2 inch include the Falcon K101 (Grade 1, 1-3/8 inch to 2-1/4 inch) and the Corbin Russwin CL3110 (Grade 1, 1-3/4 inch to 2 inch), both non-keyed passage units.
11) What is the CLUTCH system on the Cal-Royal Pioneer SL locks and why does it matter?
When the lock is secured, the outside lever spins free instead of resisting. Someone hanging on the handle or kicking down on it turns air rather than loading the spindle, which is the usual way a lever lock fails in a public building. The inside lever stays fixed and always retracts the latch. Individual springs on each side also keep the levers from sagging, the other common maintenance callback on lever hardware.
12) Can the CSL05 be keyed to match the rest of my building's Cal-Royal locks?
The CSL05 uses a 6-pin "C" keyway cylinder and is keyed to individual job requirements, so it can be brought into an existing keying schedule. Each lock comes with 2 keys. It is a single cylinder, keyed outside only, with no key needed from the inside.
13) Does the CSL05 meet ADA requirements for lever operation?
Yes. The CSL05 meets ADA requirements and is built for barrier-free applications, which is why it is a lever rather than a knob. On an accessible route the door needs hardware operable without tight grasping or twisting, and a lever satisfies that where a knob does not.
14) Is there a way to mount the CSL05 so the levers can't be pulled off a hollow core or abused door?
The CSL05 supports optional thru-bolt installation, where the two roses are bolted through the door to each other rather than relying only on the door face. On abuse-prone openings, thru-bolting is what keeps the trim from working loose. The front plate is 2-1/4 x 1-1/8 inches and adjusts for flat or beveled doors up to 1/8 inch in 2 inches, so it sits flush on a beveled edge.
15) I need the same lever look on the non-locking doors down the hall. What do I order?
The CSL05 is the keyed storeroom lock only; it does not cover passage or privacy openings. For the unlocked doors, a Grade 2 cylindrical passage lever will match the duty level, for example the Falcon B101 or the Hager 2510, both Grade 2 passage functions. Lever style will not be identical to the Pioneer SL, so if visual match across the corridor matters, pick one family for the whole run.
16) Can I use a passage lever in place of the Cal-Royal CSL05 to save on the keyed cylinder?
No - the CSL05 is a keyed, single cylinder lock, and a passage lever has no cylinder and never latches locked. Passage levers such as the Falcon B101 (Grade 2, non-handed), the Hager 2510 (Grade 2, doors 1-3/8 inch to 2 inch) or the Design Hardware J75 (Grade 2, 1-3/4 inch doors) belong on corridor, hall and closet doors that only need the latch held. If the room has to stay secured against anyone without a key, the storeroom function is what does that job.
17) What lever should I use on a store room if I want keyless code entry instead of keys?
The Cal-Royal CSL05 is a keyed lock with a 6-pin C keyway cylinder supplied with two keys. To remove keys from the door entirely, the Delaney LP250 is a Grade 2 electronic keypad leverlock, and the Lockey 2835 is a mechanical pushbutton keyless lever lock for doors 1 3/16 inch to 2 inch thick. Note that the Lockey 2835 is a passage function unit, so it does not hold the outside lever locked the way a storeroom lock does - it controls entry at the keypad instead.
18) Which lever locks look like a substitute for a Cal-Royal CSL05 but will not secure the door?
Dummy trim is the common mix-up. The BEST 7KC single dummy trim (Grade 2), the BEST 9K 1DT single dummy trim (Grade 1, heavy duty), the Accentra 455LN Augusta (Grade 1 single dummy) and the Callan Bentley 5051 (Grade 2 dummy) all mount a matching lever on the door but carry no latch and no cylinder - they are pull trim only. The CSL05 is a keyed cylindrical storeroom lock with a solid brass 1/2 inch throw latchbolt, so a dummy will not replace it on any door that has to latch.
19) What is the difference between a storeroom lever and a classroom lever when I am picking hardware for a school?
Both keep an outside lever that is controlled by key, but the intent differs. The Cal-Royal CSL05 is storeroom function, ANSI F84: the outside lever stays locked and the key only retracts the latch for entry, so the door is never left unlocked. Classroom function instead lets a key set the outside lever unlocked so a room can be opened for a period and relocked. The Dexter C1000 Classroom is a Grade 1 clutching keyed lever for doors 1-3/8 inch to 1-3/4 inch, and the Dexter C1000 Classroom Security is the Grade 1 version keyed from both sides. Supply rooms and mechanical rooms take storeroom; teaching spaces usually take classroom.
20) Is a residential Grade 3 keyed lever an acceptable swap for a Cal-Royal CSL05 on an apartment building storage room?
They are not equivalent. The CSL05 is a commercial Grade 2 lock conforming to ANSI/BHMA A156.2 Series 4000 and tested past 400,000 cycles. Grade 3 keyed levers such as the Master Lock BC series keyed entry lever and the Callan Artino entrance leverset sit at a lighter duty rating, and they are entrance function rather than storeroom, so the outside lever can be left unlocked. On a shared storage or mechanical room where the door must stay secured and sees constant traffic, the Grade 2 storeroom lock is the one that matches the application.
21) I need a keyed lever for a utility or patient room where the lever must be locked from both sides - does the Cal-Royal CSL05 do that?
No. The CSL05 is storeroom function with the inside lever always free for immediate egress, which is what most commercial and life-safety openings require. Where a room genuinely needs key control on both faces, asylum function is the correct call: the Arrow MK33-BD-CS is a Grade 2 asylum lock with a ball knob and a Schlage C keyway conventional cylinder, and the Dexter C1000 Asylum is the Grade 1 F87 version for doors 1-3/8 inch to 2 inch. Confirm the egress requirement for the room type before specifying either.
22) What finishes does the Cal-Royal CSL05 come in?
Three: US3 polished brass, US26D satin chrome, and US10B oil-rubbed bronze. The exposed trim is wrought brass, bronze or stainless steel with zinc-cast levers plated to match whichever finish you pick. US26D is the usual choice when you are matching existing commercial hardware in a school or office; US10B and US3 are for openings where the look is part of the spec.
23) Can I match a Cal-Royal CSL05 with a knob instead of a lever on the same job?
The CSL05 is a lever design, built to meet ADA requirements for barrier-free operation. Knob equivalents exist in the same cylindrical family - the Arrow RL series HK11-BB is a turn-pushbutton entrance lock with a ball knob for doors 1-3/8 inch to 1-3/4 inch, and the Arrow MK02-TA is a privacy lock with a Tudor knob - but a knob does not satisfy the barrier-free operation the lever provides. On accessible routes and public-facing doors, keep the lever.
24) Which lever should go on the restroom door if the Cal-Royal CSL05 goes on the supply room?
A storeroom lock is key-only entry, which is wrong for a restroom. Privacy function is what that door takes: the Hager 2540 is a Grade 2 privacy cylindrical lock with a Withnell lever for doors 1-3/8 inch to 2 inch, and the Accentra 5301LN Augusta is a Grade 2 cylindrical lever in passage/closet function for doors that need no locking at all. Pairing the CSL05 on secured rooms with a privacy lever on restrooms keeps one Grade 2 commercial level across the floor.
