Cal-Royal SC8473 SS US26D – Frequently Asked Questions

1) What does the dormitory function on the Cal-Royal SC8473 actually do at the door?
It is a dormitory/bedroom function keyed mortise lockset with a deadbolt, the arrangement used on apartment and dorm entries: key control outside, and the occupant can secure the door from inside. The deadbolt throws 1 inch and the latch bolt throws 3/4 inch, so you get a real deadlocking bolt rather than latch-only security. The outside lever uses a free-wheeling clutch that spins when the lock is secured, so someone forcing the lever does not break the spindle.
2) Do I have to specify hand when ordering the Cal-Royal SC8473?
No handing to call out. The SC8473 lock body is field reversible, so one part number covers left and right hand openings, and the auxiliary latch is a non-handed stainless steel design. For a property manager stocking spares across a building, that means one lock body on the shelf instead of two.
3) Can I key the Cal-Royal SC8473 into my existing BEST small format interchangeable core system?
Yes. The interchangeable core version accepts compatible 6 or 7 pin SFIC cores from BEST, FALCON and ARROW, so it folds into an existing SFIC masterkey system without rekeying the building. Ordered standard, it comes with a 6-pin solid brass C keyway cylinder.
4) Is the Cal-Royal SC8473 approved for a 3-hour fire rated door?
Yes. It is UL and cUL Listed to the Canadian safety standard for A label, which is a 3-hour fire door, and carries the stamped letter F and UL symbol on the armor faceplate for the inspector. It also meets positive pressure requirements under UL 10C and UBC 7-2 (1997).
5) Will the Cal-Royal SC8473 hold up to dormitory traffic, and does it meet ADA?
It is a Grade 1 commercial lockset conforming to ANSI/BHMA A156.13 Series 1000 for both operational and security Grade 1, tested to exceed 1,000,000 cycles. The lock case is wrought steel with zinc dichromate plating, the deadbolt is hardened stainless. It is a lever design that meets ADA requirements for barrier free application, so it works in student housing, healthcare and government buildings where levers are mandatory.
6) Can I use the Cal-Royal SC8473 where a Schlage L9000 mortise lock is being replaced?
Yes. The Cal-Royal SC8473 retrofits Schlage L9000 Series mortise locks without drilling additional holes for both sectional and escutcheon trims, and it carries a 2-3/4 inch backset with 3-7/8 inch center-to-center for 1-3/4 inch doors. If you are staying within the Schlage L family instead, the L0170 is a Grade 1 heavy duty half dummy trim for 1-3/4 inch doors, which is trim only and not a working lockset.
7) My door is 1-5/8 inch thick. Can I still use the Cal-Royal SC8473?
The Cal-Royal SC8473 is built for 1-3/4 inch doors. For a thinner leaf, the Alarm Lock DL2700CR Trilogy T2 electronic mortise lock is rated for doors 1-5/8 to 1-7/8 inch, as are the DL3500CR and the DL4500 mortise deadbolt, all Grade 1. Confirm the function you need against those, since the DL2700CR and DL3500CR are classroom function and the DL4500 is a deadbolt.
8) What is the closest equivalent to the Cal-Royal SC8473 dormitory mortise lock from another manufacturer?
The Sargent 7925 is the nearest match in function: it is a Grade 1 heavy duty mortise lock in the 7900 Series with a corridor/dormitory function and a single cylinder deadbolt, using rose trim. The Cal-Royal SC8473 is likewise a Grade 1 dormitory function mortise lockset, with a 2-3/4 inch backset, a 1 inch throw deadbolt and a 3/4 inch throw latch, and it is offered with sectional or wide escutcheon trim rather than rose only. The SC8473 also takes 6 or 7 pin BEST, FALCON and ARROW SFIC cores, so on a site already keyed to small format interchangeable core the Cal-Royal drops into the existing keying system directly.
9) What should I order if I want keypad or credential access on a dorm door instead of a mechanical key?
Move to an electronic mortise lock. The Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes and classroom function for 1-5/8 to 1-7/8 inch doors, the BEST 45HZ EZ Series is an electronic keypad mortise lock with key override, and the Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating. The Cal-Royal SC8473 is a mechanical lockset with no electronic function, keyed only through its cylinder.
10) We are replacing apartment entry locks. Is the Baldwin 6301 an alternative to the Cal-Royal SC8473?
Both serve apartment doors but they are not drop-in equals. The Baldwin 6301 is an entry/apartment mortise lock body with a 2-1/2 inch backset, available knob by knob or lever by lever, for doors 1-3/4 inch and over. The Cal-Royal SC8473 uses a 2-3/4 inch backset with a 3-7/8 inch center-to-center from lever to cylinder, so the existing door prep decides which one fits without new boring.
11) What trim and finish do I need to pick when ordering the Cal-Royal SC8473?
Two choices on the order. Trim comes in sectional or wide escutcheon styles across the AE, AS, GE, GS, HE, HS, JE, JS, SE, SS, TE, TS, WE and WS designs (the E suffix being escutcheon, S sectional). Finishes are US3 polished brass, US4 satin brass, US10B antique bronze oiled, US26D satin chrome and US32D satin stainless steel. Match US26D or US32D if you are standardizing with existing commercial hardware.
12) Will the 3/4 inch latch on the Cal-Royal SC8473 work with my existing ANSI strike?
The one-piece stainless latch bolt throws 3/4 inch with an anti-friction reversible tongue, and the separate hardened stainless deadbolt throws a full 1 inch. Those are the standard throws for an A115.1 mortise prep, so an existing ANSI mortise strike with a deadbolt cutout will catch both. A strike cut only for a latch will not accept the 1 inch deadbolt.
13) I need a classroom mortise lock, not dormitory. What else is there?
The SC8473 is dormitory/bedroom function only, so it is the wrong pick for a classroom opening. For classroom function in a Grade 1 mechanical mortise lock, the Corbin Russwin ML2003 of the ML2000 Series is the direct equivalent and is also built for 1-3/4 inch doors. If you want an electronic classroom lock with intruder lockdown instead, the TownSteel FME-4000 Series is Grade 1 heavy duty with RFID.
14) Is there an electronic or credential-based alternative to the Cal-Royal SC8473 for apartment doors?
The SC8473 is purely mechanical, keyed, with no electronics. If you want to drop keys for codes or credentials on an apartment opening, the Schlage Electronics LE Series LEBMB-ADD is a mobile-enabled mortise lock covering privacy, office and apartment functions, and the Dormakaba E-Plex 2066 Series is a keyless pushbutton mortise lock. Both trade mechanical simplicity for battery and programming upkeep.
15) Is there a simpler non-keyed mortise lock if the door does not need a key or deadbolt?
Yes. For an opening that only needs latching, the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, and the Falcon MA101 is a Grade 1 heavy duty mortise passage lock in the MA Series with field reversible operation and a fire rating. The Cal-Royal SC8473 is a keyed lockset with a 6-pin solid brass C keyway and a 1 inch throw deadbolt, so it carries hardware a passage opening does not use.
16) Will a Sargent 4874 mortise deadbolt do the same job as the Cal-Royal SC8473?
No. The Sargent 4874 in the 4870 Series is a double cylinder mortise deadbolt with a 2-3/4 inch backset, so it provides a bolt only and no latch or lever. The Cal-Royal SC8473 shares the 2-3/4 inch backset but is a complete lever lockset with a 3/4 inch throw latch bolt plus a 1 inch throw deadbolt and sectional or escutcheon lever trim. If the door needs latching and lever operation, the deadbolt alone will not cover it.
17) What is the difference between the Cal-Royal SC8473 and a BEST 45H mortise lock body?
The BEST 45H is sold as a heavy duty mortise lock body in the 45H Series with a public entrance function and field reversible operation, which means trim is specified separately. The Cal-Royal SC8473 is supplied as a complete dormitory function lockset with lever trim in sectional or wide escutcheon styles and finishes including US3 polished brass, US4 satin brass, US10B antique bronze oiled, US26D satin chrome and US32D satin stainless steel. Both are field reversible, so neither requires handing at the time of order.
18) Which mortise lock should I specify for a behavioral health room instead of the Cal-Royal SC8473?
For anti-ligature openings, look at the TownSteel MRX-L-01, a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, or the MRX-A-01, the same passage function with satin stainless ligature resistant arch trim. The Marks USA 5PDN is a Grade 1 ligature resistant hospital passage mortise push/pull paddleset in satin stainless that is ADA compliant. The Cal-Royal SC8473 uses a conventional clutch lever and a keyed dormitory function, which is a standard lever profile rather than a ligature resistant one.
19) What is a good match to the Cal-Royal SC8473 if I need an office or privacy function on the same door type?
The Hager 3800 Series covers adjacent functions at the same 2-3/4 inch backset: the 3850E is a Grade 1 office mortise lock with lever and escutcheon, non-keyed, for doors 1-3/4 to 2-1/2 inch, and the 3840S is a Grade 1 privacy mortise lock for doors 1-3/4 to 2 inch. The Cal-Royal SC8473 shares the 2-3/4 inch backset and suits 1-3/4 inch doors, but it is a keyed dormitory function with a deadbolt.
20) I need the mortise lock tied into an access control system with electric lock or unlock. What replaces the Cal-Royal SC8473?
Use an electrified mortise body. The Command Access ML190 Series is a heavy-duty motorized mortise lock with field selectable EL/EU operation on 24VDC in storeroom function, the BEST 45HW is a heavy duty wired electromechanical mortise lock with 12V/24V operation, and the Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock with request to exit on 12/24VDC for 1-3/4 inch doors. The Cal-Royal SC8473 is mechanical only.
21) Is a cylindrical lock like the Schlage PC10 interchangeable with the Cal-Royal SC8473?
No. The Schlage PC10 is a Grade 1 passage cylindrical lock, non-keyed with rose, for 1-3/4 inch doors, and it installs into a bored cylindrical prep. The Cal-Royal SC8473 is a mortise lockset requiring a mortise pocket in the door edge, with an 8 inch by 1-7/32 inch brass or stainless armor faceplate. Switching between the two means changing the door prep entirely.
22) Do the Emtek Brisbane or Memphis mortise entrance sets work as a substitute for the Cal-Royal SC8473?
No. The Emtek 3019 Brisbane and 3102 Memphis mortise entrance locksets are dummy function, as are the 3104 Hamilton and 3106 Manhattan, meaning they are non-operating trim for an inactive leaf. The Cal-Royal SC8473 is a keyed, commercial Grade 1 dormitory lockset with an operating latch and deadbolt, so the Emtek dummy sets can only be used alongside it on a second leaf, not in place of it.
