Built for doors ranging from 1-3/8" to 1-3/4" thickness with a standard 2-3/4" backset (2-3/8", 3-3/4", and 5" optional), this lockset features an ANSI Function F77 privacy/patio configuration and meets ANSI/BHMA A156.2 Series 4000, Grade 2 requirements, exceeding 400,000 test cycles.

Cal-Royal SL10-26D – Frequently Asked Questions

1) Will the Cal-Royal SL10 patio lever fit a 1-3/8 inch door, or does it need a 1-3/4?
Both work. The SL10 Pioneer SL Series lever lock is built for doors 1-3/8 inch to 1-3/4 inch thick, which covers standard commercial 1-3/4 inch openings and the older 1-3/8 inch interior doors you find in apartments and hotel rooms. Nothing extra to specify for thickness inside that range.
2) What backset do I order for a Cal-Royal SL10, and does it fit a 2-3/8 inch prep?
Backset is a required choice at order time on the SL10: 2-3/4 inch standard, or 2-3/8 inch. So yes, it drops into a 2-3/8 inch bored prep as long as you select that option. Note the faceplate changes with it, the 2-3/4 inch backset uses a 2-1/4 x 1-1/8 inch front and the 2-3/8 inch backset uses the optional 2-1/4 x 1 inch front. Cal-Royal also lists 3-3/4 inch and 5 inch backsets as options on this lock for wide stile or unusual preps.
3) What does the F77 patio function actually do on a door?
F77 is a privacy/patio setup. The outside lever is locked with a push button from inside, and it unlocks either by turning the inside lever or by closing the door. The latchbolt is deadlocked by the lever from either side. Practically that means nobody gets in from the corridor or patio side while the button is set, and anyone inside always gets out in one motion with no key and no thumbturn to hunt for. There is no keyed cylinder in this lock at all.
4) Is the Cal-Royal SL10 lever handed, and can I use it on a left hand door?
Handing is not a problem here. The SL10 latchbolt is reversible for right hand or left hand doors, so one part number covers either swing. Levers use an individual spring on each side to keep them from sagging over time, which is the usual failure you see on cheap levers in an apartment turnover.
5) Will a Cal-Royal SL10 latch into the strike that is already in my frame?
The SL10 has a 1/2 inch throw solid brass latchbolt, which is the normal throw for a cylindrical bored lock, so it will engage a standard ASA or lipped strike already in a hollow metal or wood frame. An ASA strike ships with the lock as standard; a T strike and a full lip strike are available on request if your frame prep or door gap calls for one. The latch front is adjustable for flat or beveled doors at 1/8 inch in 2 inches, so a beveled edge does not require a different part.
6) Is the Cal-Royal SL10 ADA compliant for a barrier free restroom?
Yes. The F77 privacy function on the SL10 is specifically built for barrier free application, and the lever trim itself is the ADA operable part, no tight grasping or wrist twisting to release the lock. From inside, turning the lever alone retracts the latch and cancels the push button.
7) Does the Cal-Royal SL10 take a key from the outside for staff access?
No. The SL10 is a non-keyed lock, there is no cylinder on either side. If you need housekeeping or maintenance to get through a locked door with a key, this is the wrong function and you want an entrance or storeroom lock instead. ZenSupply stocks keyed cylindrical levers for that, including the Hager 2525 entry and the Hager 2580 Withnell storeroom, both Grade 2 for 1-3/8 to 2 inch doors.
8) What is the closest equivalent to the Cal-Royal SL10 privacy lever from another brand?
The Cal-Royal SL10 is a Grade 2 non-keyed cylindrical lever with a Patio/Privacy function for doors 1-3/8 inch to 1-3/4 inch thick. The nearest peer in lever form is the Hager 2540 Grade 2 privacy cylindrical lock with the Withnell lever, which covers a wider 1-3/8 inch to 2 inch door thickness range. Both are Grade 2 cylindrical bored locks, so the door prep is the same family of work; the difference to confirm before you swap is the door thickness at the opening and the lever style your other doors already carry.
9) I need a privacy lock but the doors are 1-3/4 inch to 2 inch thick - what should I use instead of the SL10?
The Cal-Royal SL10 is built for doors 1-3/8 inch to 1-3/4 inch thick, so a 2 inch door is outside it. The Arrow MK02-TA is a privacy cylindrical lock rated for 1-3/4 inch to 2 inch doors and carries a fire rating, but it is a Tudor knob rather than a lever, which matters if the opening has to stay barrier-free. If the trim must be a lever on a thicker door, the Hager 2540 privacy lock with the Withnell lever runs 1-3/8 inch to 2 inch.
10) Is a passage lever the same thing as the Cal-Royal SL10?
No. The Cal-Royal SL10 uses the F77 patio/privacy function, which deadlocks the latchbolt and locks the outside lever from a push button on the inside. A passage lever has no locking at all - it just retracts the latch from either side. Passage peers at the same Grade 2 level include the Falcon B101 non-handed passage lever, the Accentra 5301LN Augusta, and the Hager 2510 with the Withnell lever. Order a passage lever only for a door that never needs to be secured from the inside, such as a corridor or closet.
11) What should I specify instead of the SL10 if the opening needs a keyed lock?
The Cal-Royal SL10 is non-keyed - it locks by push button only, with no cylinder. For a keyed opening at the same Grade 2 level, the Hager 2525 is a commercial cylindrical entry lever lock and the Falcon B511CP6D is a Grade 2 entry/office lever. If the door has to stay locked outside with free egress inside, the Hager 2580 is a Grade 2 storeroom lock with the Withnell lever. Grade 1 keyed options in lever form include the Dexter C1000 entry/office and the Dexter C1000 classroom.
12) Is a Grade 2 lever like the Cal-Royal SL10 enough for a restroom in a school or office, or do I need Grade 1?
The SL10 conforms to ANSI/BHMA A156.2 Series 4000 Grade 2 and exceeds 400,000 test cycles, which covers a public restroom, patio door, or guest room in an office, school, hospital, hotel, or multi-tenant building. Where you would step up is a high abuse opening that takes constant institutional traffic. For those, ZenSupply carries Grade 1 cylindrical levers such as the Corbin Russwin CL3110 vandal resistant series and the Falcon K101, though those are passage function, not privacy.
13) What finishes does the Cal-Royal SL10 come in so I can match the other doors in my building?
Nine finishes on the SL10: US1 black, US3 polished brass, US4 satin brass, US5 antique brass, US10 satin bronze, US10BE dark oxidized satin bronze, US15 satin nickel, US26 polished chrome, and US26D satin chrome. US26D satin chrome and US15 satin nickel are the two you will most often be matching in commercial work. The levers are zinc casting plated to match the trim finish, so lever and rose read the same across a floor.
14) If I am standardizing a whole floor, what else in the Cal-Royal Pioneer SL line pairs with the SL10?
The SL10 is the patio/privacy function, so it handles restrooms, patio doors, and guest room bathrooms. For the corridor and closet doors on the same floor you need a passage function lever, and ZenSupply carries Grade 2 passage levers including the Accentra 5301LN Augusta, the Falcon B101, and the Hager 2510 Withnell, all of which sit at the same Grade 2 level as the SL10. Match the finish across them, US26D satin chrome is the common denominator.
15) Our facility standard calls for Grade 1 cylindrical levers - what takes the place of the Cal-Royal SL10?
The Cal-Royal SL10 conforms to ANSI/BHMA A156.2 Series 4000 Grade 2. Grade 1 cylindrical lever peers in the same bored-lock family include the Falcon K101 heavy duty passage lever for doors 1-3/8 inch to 2-1/4 inch with a fire rating, the Falcon T101 heavy duty passage lever, and the Corbin Russwin CL3110 vandal resistant passage lever for 1-3/4 inch to 2 inch doors, also fire rated. Those Grade 1 peers are passage function, so a Grade 1 standard and a privacy function are two separate requirements to reconcile with your spec writer before the order goes in.
16) Can I use a dummy lever in place of the Cal-Royal SL10?
No - a dummy lever is fixed trim with no latch and no lock. The Cal-Royal SL10 carries a 1/2 inch throw solid brass latchbolt and the F77 privacy function. Dummy peers such as the BEST 7KC single dummy trim, the BEST 9K 1DT Grade 1 single dummy, and the Accentra 455LN Augusta Grade 1 single dummy are for the inactive leaf of a pair or a closet door that latches by magnet. Order dummy trim only to match the look of a working lever elsewhere on the same run of doors.
17) What is the difference between the Cal-Royal SL10 and an asylum or institutional function lock?
The Cal-Royal SL10 is a patio/privacy lock: the push button on the inside locks the outside lever, and the inside lever always releases. An asylum or institution function locks both sides and is operated by key from either side, which is the opposite behavior. Peers in that function include the Arrow MK33-BD-CS heavy duty asylum lock with a ball knob and Schlage C keyway and the Dexter C1000 asylum F87 for doors 1-3/8 inch to 2 inch. Behavioral health and secure utility rooms need the asylum function; a restroom or patio door needs the SL10 style free inside egress.
18) Is there a keyless pushbutton lever that can replace the Cal-Royal SL10 on a restroom or utility door?
The Cal-Royal SL10 locks with a simple privacy push button and has no code entry. If the door needs controlled access by code instead, 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 with double combination for 1-1/8 inch to 2 inch doors. Those are code-entry devices for restricting who gets in, not privacy locks for someone occupying the room.
19) We are standardizing lever style across a building - what matches the Cal-Royal SL10 on the doors that are not privacy?
The Cal-Royal SL10 covers the privacy openings. For the corridor and closet doors on the same run, Grade 2 passage levers include the Hager 2510 with the Withnell lever for 1-3/8 inch to 2 inch doors, the Accentra 4601LN with Augusta trim, and the Design Hardware J75 flat lever for 1-3/4 inch doors. For entry doors, the Hager 2525 Grade 2 entry lever keeps the same Withnell family as the 2510 and 2540, which is the cleanest way to hold one lever shape across the three functions.
20) The SL10 is a lever - is a privacy knob an acceptable substitute?
Only where barrier-free operation is not required. The Cal-Royal SL10 lever is specifically designed for barrier-free application, which is what an ADA path of travel calls for. The Arrow MK02-TA is a Grade 2 privacy cylindrical lock with the same locking behavior but a Tudor knob, suited to 1-3/4 inch to 2 inch doors and fire rated. Knobs remain common on residential interior doors and back-of-house rooms outside the accessible route.
21) Can I thru-bolt the Cal-Royal SL10 on an abused door?
Thru-bolt installation is an available option on the SL10, which is what you want on a heavily used restroom or a door that gets pulled on. The latch and strike screws are dual purpose 8-32 x 1 inch flat phillips head, so the same screws serve either mounting approach.
22) What is the Cal-Royal SL10 lock body made of?
Wrought brass, bronze, or stainless steel body, with zinc casting levers plated to match the trim finish. The latchbolt is solid brass rather than plated steel, which matters on an exterior patio door or a humid restroom where a steel latch corrodes and starts binding.
23) For a decorative interior privacy lever instead of a commercial one, what are the options next to the Cal-Royal SL10?
The Cal-Royal SL10 is a commercial Grade 2 cylindrical lever with zinc casting levers plated to match the trim finish. On the decorative side, the Baldwin Estate 5103 privacy lever with the 5048 rose gives the same privacy function in a residential estate trim, with matching passage and left and right hand half dummy versions in the same 5103 family for the rest of the doors. Choose the commercial lockset where a cycle-rated body matters and the estate trim where the finish and rose shape drive the selection.
