Cal-Royal SC8466 SS US26D – Frequently Asked Questions

1) Will the Cal-Royal SC8466 mortise lockset drop into an existing Schlage L9000 mortise prep?
Yes. The SC8466 retrofits Schlage L9000 Series mortise locks without drilling additional holes, and that holds for both sectional and escutcheon trims. It shares the standard 2-3/4 inch backset and a 3-7/8 inch center-to-center from lever centerline to cylinder centerline, which is what makes the trim line up over the existing prep. Trims mount with no exposed screws on either face.
2) Do I have to specify hand when I order the SC8466 store door mortise lockset?
No. The lock body is field reversible, so one lock covers left and right hand openings and you flip it on site. The latch bolt uses an anti-friction reversible tongue, so the anti-friction feature works either way after reversing. That matters if you are stocking spares for a building with mixed handing.
3) Can I use my existing BEST cores in the Cal-Royal SC8466?
The interchangeable core versions accept compatible 6 or 7 pin small format cores from BEST, FALCON, and ARROW, so an existing SFIC masterkey system carries straight over. Standard (non-IC) versions ship with a 6-pin solid brass C keyway cylinder. Pick the version that matches the key system already running in the building.
4) Will the SC8466 latch and deadbolt work with an existing ANSI strike and frame prep?
The latch bolt throws 3/4 inch and the hardened stainless deadbolt throws a full 1 inch, with an 8 x 1-7/32 inch armor faceplate meeting ANSI A115.1. A frame prepped to the ANSI A115.1 mortise standard takes it without modification. If your existing strike is an older non-ANSI or a shallow box, check that the pocket is deep enough for the 1 inch deadbolt projection.
5) Is the Cal-Royal SC8466 approved for a 3-hour fire rated door?
It is UL and cUL Listed for A label, 3-hour fire doors, with the letter F and the UL symbol stamped on the armor faceplate, and it meets positive pressure requirements per UL 10C and UBC 7-2 (1997). The lock body carries ANSI/BHMA A156.13 Series 1000 Grade 1 for both operational and security, tested past 1,000,000 cycles, and the lever trim meets ADA barrier free requirements.
6) What should I order instead of the Cal-Royal SC8466 if the job calls for electronic access control on a mortise prep?
The Cal-Royal SC8466 is a mechanical, non-electronic keyed mortise lockset. For credential-based access on a mortise prep, the TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID technology for 1-3/4 inch doors, the Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating, and the Dormakaba E-Plex E5086 is a Grade 1 pushbutton and card mortise lock. All three replace the keyed cylinder as the primary means of entry.
7) Is the Falcon MA101 a substitute for the Cal-Royal SC8466?
No. The Falcon MA101 is a Grade 1 heavy duty MA Series mortise lock with a passage/hall/closet function and field reversible operation, so it has no cylinder and does not lock. The Cal-Royal SC8466 is keyed, with a 6-pin solid brass C keyway standard and interchangeable core versions that accept 6 or 7 pin BEST, FALCON and ARROW SFIC cores. Both are field reversible, but the MA101 only suits an opening that needs latching without locking.
8) I have an ornamental iron door with a 1 inch stile. Will the Cal-Royal SC8466 work, or do I need something else?
The Cal-Royal SC8466 is built for 1-3/4 inch thick doors with a 2-3/4 inch backset only, so it will not suit a 1 inch iron stile. The Marks USA 21AC and 22AC are entrance double cylinder ornamental iron mortise locks with round knobs listed for 1 inch door thickness, and the Kaba Ilco BR Series is a glass door bottom rail lock for that style of opening.
9) My opening needs electric lock/unlock with request to exit. Can the Cal-Royal SC8466 do that?
No. The Cal-Royal SC8466 is a mechanical mortise lockset with no electronic components. For an electrified mortise prep, the Schlage L9092EU with 03A trim is a heavy duty corridor function electric lock/unlock outside lever mortise lock, keyed outside, with request to exit and 12/24VDC operation on 1-3/4 inch doors, and the Command Access ML190 Series is a heavy duty motorized storeroom mortise lock with field selectable EL/EU operation at 24VDC.
10) What is a store door function mortise lock and when should I use it instead of a storeroom lock?
A store door function keeps the outside lever always active for entry when unlocked and pairs the latch with a separate deadbolt you throw at closing time, which is why it suits retail storefronts and tenant suites that lock down after hours. If you only need the outside lever to stay locked at all times with key entry and no deadbolt, a storeroom function lock like the Accentra 8805FL is the simpler choice. The SC8466 is the keyed, mechanical option, not electronic.
11) What trim and finish options do I need to pick when ordering the SC8466?
Two choices on the order. Finish: US3 polished brass, US4 satin brass, US10B antique bronze oiled, US26D satin chrome, or US32D satin stainless steel. Trim: sectional or wide escutcheon in the AE, AS, GE, GS, HE, HS, JE, JS, SE, SS, TE, TS, WE and WS designs, where the E suffix is escutcheon and the S is sectional. Handing is not a choice, since the body reverses in the field.
12) Will the lever break if someone forces it while the door is locked?
The outside lever uses a free-wheeling clutch, so it spins freely when the lock is secured rather than transferring force into the spindle or hub. That is the failure point on abused entrances, and it is the reason this one holds up in high-traffic retail and multi-tenant buildings. The case itself is wrought steel with zinc dichromate plating, with a hardened stainless deadbolt and a one-piece stainless latch bolt.
13) Will an Alarm Lock Trilogy mortise lock fit the same door as the Cal-Royal SC8466?
Check the door thickness before ordering. The Alarm Lock DL2700CR classroom, DL3500CR classroom, and DL4500 deadbolt are Grade 1 electronic mortise locks listed for doors 1-5/8 inch to 1-7/8 inch, a range that includes 1-3/4 inch. The Cal-Royal SC8466 is specified for 1-3/4 inch doors, so a 1-3/4 inch leaf suits both; the Trilogy units add keypad codes, while the SC8466 is a keyed mechanical lockset.
14) The Cal-Royal SC8466 retrofits Schlage L9000. Is a Schlage L0170 an equivalent lock?
No. The Schlage L0170 is a Grade 1 heavy duty L Series half dummy trim, a non-keyed dummy for 1-3/4 inch doors with no working latch or cylinder. The Cal-Royal SC8466 is a keyed store door mortise lockset with a 3/4 inch latch throw and a 1 inch deadbolt throw that retrofits Schlage L9000 Series mortise locks without drilling additional holes. Use the L0170 only on an inactive leaf where pull-only trim is wanted.
15) If I only need a mortise deadbolt and not a full lockset like the Cal-Royal SC8466, what are my options?
The Sargent 4874 is a double cylinder mortise deadbolt in the 4870 Series with a 2-3/4 inch backset, the same backset the Cal-Royal SC8466 uses, and the Kaba Ilco 185 Series is a no-handing mortise deadbolt. The SC8466 combines a keyed lever with a 3/4 inch latch and a 1 inch deadbolt in one case, so a standalone deadbolt suits an opening where the latching is already handled by other hardware.
16) Does the BEST 45H mortise lock body do the same job as the Cal-Royal SC8466?
The BEST 45H is a heavy duty mortise lock body with a public entrance function and field reversible operation, and the 45HCA Series offers an intruder function lock body. Those are lock bodies, so trim is specified separately. The Cal-Royal SC8466 is supplied as a complete lever lockset with sectional or wide escutcheon trim options and five finishes including US26D satin chrome and US32D satin stainless steel, and its lock body is field reversible as well.
17) What is a Grade 1 mortise alternative to the Cal-Royal SC8466 for a dormitory or corridor opening with a deadbolt?
The Sargent 7925 is a Grade 1 heavy duty mortise lock in the 7900 Series with a corridor/dormitory exit function, rose trim, and a single cylinder deadbolt. The Cal-Royal SC8466 is a Grade 1 store door mortise lockset with a 1 inch deadbolt throw, a 2-3/4 inch backset, and sectional or wide escutcheon trim. Both carry a deadbolt; the difference is the operating function and whether rose or escutcheon trim is wanted.
18) Can I use a Hager 3800 Series mortise lock in place of the Cal-Royal SC8466?
The Hager 3800 Series covers non-keyed functions: the 3810E and 3810S are Grade 1 passage mortise locks with a 2-3/4 inch backset for 1-3/4 inch to 2-1/2 inch doors, the 3850E is an office function lock listed as non-keyed, and the 3840S is a privacy function lock for 1-3/4 inch to 2 inch doors. The Cal-Royal SC8466 shares the 2-3/4 inch backset and fits 1-3/4 inch doors, but it is keyed with a 6-pin C keyway, so the Hager units are substitutes only where keyed entry is not required.
19) What should I specify instead of the Cal-Royal SC8466 for a behavioral health or ligature-resistant opening?
The TownSteel MRX-L-01 is a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset with a passage function for 1-3/4 inch doors, the MRX-A-01 is the same passage function with satin stainless ligature resistant arch trim, and the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel. The Cal-Royal SC8466 is a keyed lever lockset, so it is the right choice only where a standard lever and cylinder are acceptable.
20) Can I standardize the SC8466 across a whole building of commercial openings?
It is built for that. One field reversible body covers every handing, the lock is rated Grade 1 past 1,000,000 cycles for offices, schools, healthcare, retail, warehouses, multi-tenant residential and government buildings, and the IC versions let you fold every door into one SFIC key system using BEST, FALCON or ARROW cores. Pick a single finish and trim design and the whole fleet matches.
21) Are the Emtek mortise entrance locksets an alternative to the Cal-Royal SC8466?
They serve a different purpose. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton, and 3106 Manhattan mortise entrance locksets are all dummy function, meaning no latch operation. The Cal-Royal SC8466 is a keyed commercial store door mortise lockset with a working 3/4 inch latch and 1 inch deadbolt, offered in finishes including US3 polished brass, US4 satin brass, and US10B antique bronze oiled.
