Cal-Royal SC8080 Grade 1 Storeroom Mortise Lockset with Interchangeable Core Compatibility

The Cal-Royal SC8080 is a Grade 1 storeroom mortise lockset engineered for 1 ¾" (44.5mm) thick doors with a 2 ¾" (70mm) backset and 3 7/8" (98mm) center-to-center dimension.

Cal-Royal SC8080 SS US26D – Frequently Asked Questions

1) Will the Cal-Royal SC8080 mortise lock fit my existing Schlage L9000 prep?
It will. The SC8080 retrofits Schlage L9000 Series mortise locks without drilling any additional holes, for both sectional and escutcheon trims. That matters on a retrofit because the L9000 pocket, cross-bore and trim holes are already in the door, so you're swapping the lock body and trim rather than re-prepping. It shares the same 2-3/4 inch backset and 3-7/8 inch center-to-center between lever and cylinder, and the armor faceplate is 8 x 1-7/32 inches per ANSI A115.1 prep.
2) What door thickness does the Cal-Royal SC8080 mortise lockset take?
1-3/4 inches, the standard commercial door thickness. It is a single-thickness lock, so if your doors are 1-3/8 inch older interior slabs or anything thicker than 1-3/4, this is not the right body. For thicker openings, the Hager 3800 Series mortise locks we carry cover 1-3/4 to 2-1/2 inches, though those are passage and office functions rather than keyed storeroom.
3) Do I have to specify handing when I order a Cal-Royal SC8080?
No handing to call out. The SC8080 lock body is fully field reversible, so one part number covers left and right hand openings and the anti-friction latch tongue flips in the field. The auxiliary latch is non-handed as well. For a property manager buying spares across a building, that means a single lock on the shelf fits any door in the stack.
4) Can I put my building's BEST small format interchangeable cores in the Cal-Royal SC8080?
The IC versions accept compatible 6 or 7 pin SFIC cores from BEST, FALCON and ARROW, so a facility already keyed on BEST small format can core these up and fold them straight into the existing master key system. Ordered without IC, the lock ships with a 6-pin solid brass "C" keyway cylinder.
5) Will the Cal-Royal SC8080 latch into the strike that's already in my frame?
Check the frame prep against the lock's numbers before you assume it drops in. The latch bolt throws 3/4 inch and the deadbolt throws 1 inch, and the lock ships with a brass or stainless strike per ANSI A115.1 with a curved lip and dust box. If your existing frame is cut to the A115.1 strike prep, the supplied strike drops into it. If it was cut for a different strike outline, use the strike that comes with the lock rather than trying to reuse the old one, since the 1 inch deadbolt needs the dust box depth behind it.
6) Is the Cal-Royal SC8080 rated for a fire door?
It is UL and cUL Listed for an A label 3-hour fire door, and the armor faceplate carries the stamped letter F and the UL symbol so an inspector can verify it in place. It also meets positive pressure requirements per UL 10C and UBC 7-2 (1997). Being a storeroom function, the outside lever stays locked at all times and the inside lever always retracts the latch for free egress, which is what a fire-rated opening needs.
7) What does storeroom function mean on a Cal-Royal SC8080, and is it the right function for a mechanical room or supply closet?
Storeroom is the standard choice for a room that must never be left unlocked. The outside lever is always rigid and only the key retracts the latch; the inside lever always works for egress. There is no way for staff to leave it in an unlocked state by mistake, which is why it goes on mechanical rooms, IT closets, janitor and supply rooms. If you want a room that can be left open during business hours, storeroom is the wrong function, and if you need a classroom function instead, the Corbin Russwin ML2003 is a Grade 1 classroom mortise lock for the same 1-3/4 inch door.
8) What is a direct Grade 1 storeroom mortise lock alternative to the Cal-Royal SC8080?
The Accentra 8805FL from the 8800 Series is a Grade 1 storeroom mortise lock, matching the SC8080 on both grade and storeroom function. The SC8080 is a Grade 1 storeroom mortise lockset with a lever handle and a field reversible lock body, so handing does not have to be specified when ordering; the 8805FL is supplied with the Arcadia lever. Both put a keyed storeroom function in a mortise pocket, so either one covers a stock room, mechanical room, or utility closet that must latch locked at all times.
9) We want to add keypad or credential access to a storeroom - what replaces a mechanical mortise lock like the SC8080?
The Cal-Royal SC8080 is a mechanical lockset with no electronics, keyed to a 6-pin solid brass C keyway with interchangeable core versions accepting 6 or 7 pin BEST, FALCON, and ARROW SFIC cores. For credentialed access in the same mortise pocket, the BEST 45HZ EZ Series is an electronic keypad mortise lock with key override, and the Alarm Lock DL3500CR of the DL3500 Series is a Grade 1 electronic mortise lock with 300 user codes, though it is a classroom function lock for 1-5/8 to 1-7/8 inch doors. For RFID credentials, the TownSteel FME-2000 Series is a Grade 1 heavy duty mortise lockset with RFID technology for 1-3/4 inch doors. An electronic lock adds power, programming, and audit requirements the SC8080 does not carry.
10) What mortise lock should be used instead of the SC8080 on a door thinner than 1-3/4 inch?
The Cal-Royal SC8080 is engineered for 1-3/4 inch thick doors. For a thinner door, the Baldwin 6310 entry/storeroom mortise lock body covers 1-3/8 inch and over with a 2-1/2 inch backset, available knob by knob or as the 6310190RRLS lever by lever in right hand reverse. The Marks USA 21AC and 22AC are ornamental iron mortise locks for 1 inch doors with a round knob and double cylinder entrance function, sized for narrow iron stile gates and doors. Note the Baldwin bodies use a 2-1/2 inch backset where the SC8080 uses 2-3/4 inch, so the cross-bore and pocket location differ.
11) The storeroom door needs electric lock/unlock control - what mortise lock handles that where the SC8080 cannot?
The Cal-Royal SC8080 is a mechanical lockset with no electronic operation, so it cannot be released from an access control panel. The Command Access ML190 Series is a heavy-duty motorized mortise lock in storeroom function with field selectable EL/EU operation on 24VDC, which keeps the same storeroom function the SC8080 provides while adding remote control. The Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock for 1-3/4 inch doors, keyed outside with request to exit on 12/24VDC, and the BEST 45HW is a heavy duty wired electromechanical mortise lock with 12V/24V operation. Each of these requires power transfer through the frame and door.
12) For a classroom lockdown requirement, what mortise lock goes in instead of a storeroom lock?
A storeroom lock like the Cal-Royal SC8080 keeps the outside lever locked at all times and is keyed from the corridor, which is not a lockdown function. The BEST 45HCAINL is a heavy duty mortise lock body with intruder function, letting the door be secured from inside the room. The TownSteel FME-4000 Series is a Grade 1 heavy duty electronic intruder classroom mortise lockset with RFID technology for 1-3/4 inch doors, matching the SC8080 door thickness. Confirm the intruder function against local egress code before specifying.
13) Is the Cal-Royal SC8080 heavy duty enough for a high-traffic commercial opening?
Grade 1, and rated past 1,000,000 cycles. The lock case is wrought steel with zinc dichromate plating, the deadbolt is hardened stainless, and the latch bolt is one-piece stainless. It conforms to ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1, which is the heaviest mortise classification and the one a spec on a commercial drawing normally calls for.
14) Do I need to order trim separately with the Cal-Royal SC8080, and what are the trim choices?
Trim is part of what you pick when you order. There are fourteen sectional and wide escutcheon trim designations: AE, AS, GE, GS, HE, HS, JE, JS, SE, SS, TE, TS, WE and WS. The paired letters run sectional and escutcheon versions of the same lever style, so pick the lever family first and then whether the opening gets a rose or a full escutcheon plate. Neither style shows exposed mounting screws on the outside or inside trim.
15) Will the lever on the Cal-Royal SC8080 break if someone yanks on it while the door is locked?
That is exactly what the clutch is for. The outside lever free-wheels when the lock is secured, so forcing it spins the lever rather than loading the spindle and hub. On a storeroom door that gets pulled on all day by people who forgot their key, it is the difference between a lever that survives and one you replace every year. It also meets ADA requirements for barrier free application, so the lever operates without tight grasping or twisting.
16) Should I use a mortise lock like the Cal-Royal SC8080 or a cylindrical lockset?
A mortise lock needs a pocket machined into the edge of the door, so it is a decision you make at the door prep, not afterward. What you get for it is a deadbolt in the same body as the latch (1 inch deadbolt throw alongside the 3/4 inch latch), which a cylindrical lock cannot give you in one operation. If your doors are already prepped with a 2-1/8 inch cross bore rather than a mortise pocket, a mortise lock is not a swap you can make without replacing or re-prepping the door, and a cylindrical unit such as the Schlage PC Series is what fits that prep.
17) I need keyless entry on a storeroom door. Is the Cal-Royal SC8080 available with a keypad or card reader?
No, the SC8080 is a mechanical keyed lock with no electronic option. If the opening needs access control, look at electronic mortise locks instead: the Alarm Lock DL3500 Trilogy is a Grade 1 keypad mortise lock with 300 user codes, the BEST 45HW is a wired electromechanical mortise lock running 12V or 24V, and the Command Access ML190 is a motorized mortise lock with storeroom function and field selectable fail safe or fail secure operation on 24VDC. The Command Access unit is the closest match if you want to keep storeroom function and add electric control.
18) What else does ZenSupply carry that is an equivalent to the Cal-Royal SC8080 storeroom mortise lock?
The straight equivalent is the Accentra 8805FL, a Grade 1 storeroom mortise lock from the 8800 Series with an Arcadia lever. If the room needs a lock body only because the trim is staying, the BEST 45H Series is a heavy duty field reversible mortise lock body, though it is public entrance function rather than storeroom. Watch out for parts that look like substitutes and are not: the Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, so it locks but has no latch or lever, and the Schlage PM010 is a passage mortise latch with no key at all.
19) Is there a mortise lock that does the same job as the SC8080 but without a key?
No - a non-keyed lock cannot secure a storeroom. The Cal-Royal SC8080 is a keyed storeroom mortise lockset, and that keyed cylinder is what holds the outside lever locked. If the opening only needs to latch and does not need to lock, the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, and the Falcon MA101 of the MA Series is a Grade 1 heavy duty mortise passage lock, fire rated and field reversible like the SC8080 body. Use a passage lock only where access control is handled elsewhere in the opening.
20) Can a mortise deadbolt be used in place of the SC8080 on a storeroom door?
Not on its own. The Cal-Royal SC8080 combines a 3/4 inch throw latch bolt with a 1 inch throw deadbolt in one case, so the door latches and secures with a single lockset. The Sargent 4874 of the 4870 Series is a double cylinder mortise deadbolt with a 2-3/4 inch backset - the same backset the SC8080 uses - but a deadbolt alone gives no latching, so the door needs separate trim or a latch to keep it closed. The Kaba Ilco 185 Series is likewise a deadbolt function mortise lock. Specify a deadbolt-only body when it is supplementing an existing latch, not replacing a storeroom lockset.
21) Is a Schlage L0170 or an Emtek mortise entrance lockset a substitute for the SC8080?
No. The Cal-Royal SC8080 is a keyed Grade 1 storeroom lockset with a working latch and deadbolt. The Schlage L0170 of the L Series is a Grade 1 heavy duty dummy trim for 1-3/4 inch doors - half dummy, non-keyed, with no latching mechanism. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton, and 3106 Manhattan mortise entrance locksets are likewise dummy function. Dummy trim is pull-only hardware for an inactive leaf; it will not secure or latch a storeroom door.
22) Is a cylindrical lock an alternative to the SC8080, or does the door have to be mortised?
The Cal-Royal SC8080 is a mortise lock and needs a mortise pocket cut into the door edge along with the 8 inch by 1-7/32 inch faceplate prep. A cylindrical lock uses a bored cross-hole instead and will not drop into a mortise pocket. Among cylindrical options, the Schlage PC10 is a Grade 1 passage cylindrical lock with rose for 1-3/4 inch doors, but it is non-keyed passage function and does not lock. A door already mortised for the SC8080 cannot take a cylindrical lock without a filler plate or door replacement.
23) For a behavioral health or ligature-resistant opening, what mortise lockset is specified instead of a standard storeroom lever?
The Cal-Royal SC8080 uses a standard lever with a free-wheeling clutch on the outside lever. Where an anti-ligature trim is required, the TownSteel MRX-L-01 is a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, and the MRX-A-01 is the same passage function with satin stainless steel ligature resistant arch trim. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant in satin stainless steel. All three are passage function, so a keyed storeroom opening needs the function confirmed against the door schedule before substituting.
24) Can a BEST 45H lock body be swapped in for a Cal-Royal SC8080?
They are different functions. The BEST 45HCA of the 45H Series is a heavy duty mortise lock body in public entrance function with field reversible operation, and the 45HCAINL is a heavy duty body in intruder function. The Cal-Royal SC8080 is storeroom function, where the outside lever stays locked and the key retracts the latch. Public entrance and intruder functions change how the door behaves for occupants, so match the function on the hardware schedule rather than the body style. Both the SC8080 body and the 45HCA are field reversible, so neither requires handing to be called out.
25) The opening is a dormitory or corridor door, not a storeroom - what mortise lock fits?
The Sargent 7925 of the 7900 Series is a Grade 1 heavy duty dormitory exit function mortise lock with rose trim and a single cylinder deadbolt, built for corridor and dormitory openings. The Cal-Royal SC8080 is a storeroom lockset, which keeps the outside lever locked at all times and is not the function for a dorm room entry. Both carry a deadbolt in the case - the SC8080 uses a hardened stainless steel deadbolt with a 1 inch throw - so the frame prep for a dead strike is similar in either direction.
26) What mortise lock covers a privacy or office opening where the SC8080 storeroom function is wrong?
The Cal-Royal SC8080 is keyed storeroom function - the outside lever is always locked, which is not appropriate for a restroom or a private office. The Hager 3840S of the 3800 Series is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for 1-3/4 to 2 inch doors, the same backset the SC8080 uses. For an office opening, the Hager 3850E is a Grade 1 non-keyed office mortise lock with lever and escutcheon on a 2-3/4 inch backset for 1-3/4 to 2-1/2 inch doors, and the 3810E and 3810S cover passage function with escutcheon and rose respectively.
27) Which mortise locks match the SC8080 on Grade 1 and 1-3/4 inch door thickness for standardizing a facility?
The Cal-Royal SC8080 is a commercial Grade 1 mortise lockset for 1-3/4 inch doors. Peers sharing both that grade and that door thickness include the Corbin Russwin ML2003 in classroom function, the Marks USA LA318GJ classroom security indicator lockset, the Schlage PM010 non-keyed passage latch, the Schlage PC10 passage lock, the TownSteel MRX-L-01 and MRX-A-01 passage locksets, and the TownSteel FME-2000 and FME-4000 classroom locksets. Standardizing on 1-3/4 inch doors at Grade 1 lets one door prep serve storeroom, classroom, and passage openings across a building.
28) What finishes does the Cal-Royal SC8080 come in, and which one matches the rest of my building?
Five finishes: US26D satin chrome, US32D satin stainless steel, US3 polished brass, US4 satin brass, and US10B antique bronze oiled. On commercial interiors the vast majority of openings run US26D, so if you are matching existing hardware in an office, school or healthcare corridor that is the likely match. US32D is the usual pick where the rest of the opening is stainless. Brass and bronze are for lobbies and higher-finish areas.
29) Can I standardize a whole facility on the Cal-Royal SC8080 across different functions?
The SC8080 covers the storeroom openings, and standardizing on it gives every one of those doors the same 2-3/4 inch backset, 3-7/8 inch center-to-center and ANSI A115.1 faceplate and strike prep, so your door prep is identical building-wide and one spare lock fits any of them. Rooms that need a different function will need a different lock, but if you core them all on the same BEST, FALCON or ARROW SFIC system the keying stays unified even where the lock bodies differ.
30) Is a Sargent 130KB thumbturn or a Falcon MESC600DT escutcheon a replacement for a mortise lockset?
No - those are trim components, not locksets. The Sargent 130KB is a standard duty mortise thumbturn from the 8200 Series and the 130W is a standard duty mortise thumbturn with a round backplate from the 7800 Series; both are turn pieces that mount to a lock, not a lock itself. The Falcon MESC600DT is a dummy escutcheon lever trim for M9900 Series exit devices, fire rated, and is trim for an exit device rather than a mortise lock. The Cal-Royal SC8080 is a complete keyed storeroom mortise lockset, ordered with the finish and the sectional or wide escutcheon trim selected on the same line.
