Cal-Royal SC8050 Grade 1 Office/Entrance Mortise Lockset with Interchangeable Core Prep

The Cal-Royal SC8050 is a Grade 1 office/entrance mortise lockset engineered for 1 ¾" (44.5mm) thick standard doors with a 2 ¾" (70mm) backset and 3 7/8" (98mm) center-to-center. Built from heavy duty wrought steel with a zinc dichromate plated lock case, this commercial mortise lock features a fully field reversible lock body, a hardened stainless steel 1" throw deadbolt, and a one-piece stainless steel ¾" throw latch bolt with anti-friction reversible tongue. It exceeds 1,000,000 test cycles per ANSI A156.13 and can retrofit Schlage L9000 Series mortise locks without drilling additional holes for sectional and escutcheon trims.

Key Features

  • Heavy-Duty Construction: Wrought steel lock case with zinc dichromate plating, hardened stainless steel 1" throw deadbolt, and one-piece stainless steel ¾" throw latch bolt with anti-friction reversible tongue.
  • Field Reversible Handing: Lock bodies are easily field reversible, eliminating the need to specify hand when ordering, with a non-handed stainless steel auxiliary latch.
  • Interchangeable Core Compatibility: Accepts compatible 6 or 7 pin interchangeable cores from BEST, FALCON, and ARROW, plus a standard 6-pin solid brass "C" keyway cylinder.
  • Armor Faceplate: Brass or stainless steel faceplate measuring 8" x 1 7/32" (203mm x 31.3mm) per ANSI Standard A115.1, with strike also available in brass or stainless steel featuring a curved lip and dust box.
  • Free-Wheeling Clutch Lever: The outside lever incorporates a clutch design that rotates when locked, reducing excessive force on the horizontal lever and decreasing the chance of breakage or damage.

Cal-Royal SC8050 SS US26D – Frequently Asked Questions

1) Will the Cal-Royal SC8050 mortise lock drop into a Schlage L9000 mortise prep?
Yes. The SC8050 retrofits Schlage L9000 Series mortise locks without drilling additional holes, for both sectional and escutcheon trims. That covers the pocket and the trim through-holes, so a straight swap on an existing L9000 opening is the normal use case for this lock.
2) Do I have to specify handing when I order the SC8050?
No. The lock body is field reversible, and the stainless steel auxiliary latch is non-handed, so one lock covers left and right hand openings. You reverse the latch on site rather than ordering a hand.
3) Will the SC8050 accept our existing BEST small format interchangeable cores?
Interchangeable core versions take compatible 6 or 7 pin SFIC cores from BEST, FALCON and ARROW, so an existing BEST keying system carries straight over. A standard 6-pin solid brass C keyway cylinder is the alternative if you are not running SFIC. Cores and cylinders are keying items ordered separately from the lockset.
4) Will the SC8050 latch and bolt into a standard ANSI strike already in my frame?
The latch bolt throws 3/4 inch and the hardened stainless deadbolt throws a full 1 inch, with an armor faceplate measuring 8 x 1-7/32 inches per ANSI A115.1. Frames prepped to the ANSI A115.1 mortise standard take it directly. A matching strike with curved lip and dust box is available in brass or stainless if the existing one is worn or not deadbolt-cut.
5) Can the Cal-Royal SC8050 go on a 3-hour fire rated door?
Yes. It is UL and cUL Listed for A label 3-hour fire doors, and the armor faceplate is stamped with the letter F and the UL symbol. It also meets positive pressure requirements under UL 10C and UBC 7-2 (1997), and meets ADA requirements for barrier free application.
6) What is a comparable Grade 1 office-function mortise lock with a 2-3/4 inch backset if the Cal-Royal SC8050 does not suit the opening?
The Hager 3850E from the 3800 Series is an office-function mortise lock with a 2-3/4 inch backset, furnished with a lever and escutcheon and non-keyed, and it covers doors from 1-3/4 inch through 2-1/2 inch thick. The Cal-Royal SC8050 is an entrance/office mortise lockset built for 1-3/4 inch doors with a 2-3/4 inch backset, so the Hager is the option when the door is thicker than 1-3/4 inch.
7) I need a mortise lock that locks the outside lever at all times instead of the office/entrance function - what should I order?
The Accentra 8805FL from the 8800 Series is a Grade 1 storeroom-function mortise lock with an Arcadia lever, which keeps the outside lever fixed and requires a key every time. The Cal-Royal SC8050 is an entrance/office function lockset, where the outside lever can be left unlocked with a toggle button. Choose the storeroom function for utility rooms and mechanical spaces that must never be left unsecured.
8) We want keypad or credential access on the door - what replaces the Cal-Royal SC8050?
The Cal-Royal SC8050 is a mechanical, non-electronic mortise lockset. For credentialed access on a 1-3/4 inch door, the TownSteel FME-2000 Series is a Grade 1 heavy-duty classroom mortise lockset with RFID, the Schlage CO-100 standalone electronic mortise lock is Grade 1 heavy duty with a keypad reader in privacy function, and the Schlage LEMD-GRW of the ENGAGE Series is a Grade 1 wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating. Dormakaba E-Plex E5086 is a Grade 1 back-to-back pushbutton and card mortise lock for entry/egress.
9) What does the office/entrance function on the SC8050 actually do day to day?
Entrance/office function: a toggle button in the lock face holds the outside lever locked or unlocked, and the key retracts the latch when locked. Inside lever always retracts the latch for free egress. There is also a separate 1 inch deadbolt for after-hours security. The toggle button is chrome plated zinc alloy for rust resistance.
10) Is the SC8050 tough enough for a high traffic building entrance?
It is ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1, tested past 1,000,000 cycles. The case is wrought steel with zinc dichromate plating, and the outside lever uses a free-wheeling clutch that spins when locked instead of transferring force into the lever, which is where most abused levers break.
11) What trim and finish choices do I pick from when ordering the Cal-Royal SC8050?
Two decisions. Trim comes in fourteen sectional and wide escutcheon designs: AE, AS, GE, GS, HE, HS, JE, JS, SE, SS, TE, TS, WE and WS. Finishes are US3 polished brass, US4 satin brass, US10B antique bronze oiled, US26D satin chrome and US32D satin stainless steel. All are lever trim, not knob.
12) Should I use a mortise lock like the SC8050 or a cylindrical lock on my commercial doors?
A mortise lock like the SC8050 pockets into the door edge and gives you a latch plus a separate 1 inch deadbolt in one case, which a cylindrical lock cannot do. It needs a full mortise pocket, so it suits doors already prepped for one or new doors being machined. If your doors carry a 161 bore instead, a cylindrical lock such as the Schlage PC Series is the fit; converting bored to mortise means new doors or a mortise kit.
13) I need a classroom or storeroom function mortise lock, not office. What should I look at instead?
The SC8050 is entrance/office only, so it will not cover those. For classroom, the Corbin Russwin ML2003 is a Grade 1 classroom mortise lock for 1-3/4 inch doors. For storeroom, the Accentra 8805FL from the 8800 Series is Grade 1 storeroom function. For passage only, the Falcon MA101 is a Grade 1 heavy duty field reversible passage mortise lock.
14) Is there a simpler non-locking mortise lock for a corridor or closet door where the SC8050 function is more than I need?
Yes. The Falcon MA101 of the MA Series is a Grade 1 heavy-duty mortise passage lock with field reversible operation and a fire rating, and the Schlage PM010 of the PM Series is a Grade 1 passage latch mortise lock, non-keyed, for 1-3/4 inch doors. Hager also offers passage in the 3800 Series with a 2-3/4 inch backset: the 3810S with a rose and the 3810E with an escutcheon, both for 1-3/4 inch to 2-1/2 inch doors. The Cal-Royal SC8050 is an entrance/office lockset with a 1 inch throw deadbolt in addition to its 3/4 inch latch, which passage locks do not carry.
15) Can I use a Baldwin 6301 or 6310 mortise lock in place of the Cal-Royal SC8050?
Not as a drop-in. The Baldwin 6301 entry/apartment and 6310 entry/storeroom mortise lock bodies use a 2-1/2 inch backset, while the Cal-Royal SC8050 is a 2-3/4 inch backset only, so the door prep and cylinder location differ. The 6301 is offered knob by knob or lever by lever for doors 1-3/4 inch and over, and the 6310 covers 1-3/8 inch and over. The SC8050 is a lever lockset for 1-3/4 inch doors.
16) What looks like a substitute for the Cal-Royal SC8050 but will not actually lock a door?
Several mortise-family items are trim or dummy parts, not working locksets. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan mortise entrance locksets are dummy function, and the Schlage L0170 of the L Series is a Grade 1 half dummy trim, non-keyed, for 1-3/4 inch doors. Sargent 130KB of the 8200 Series and 130W of the 7800 Series are mortise thumbturns only. The Cal-Royal SC8050 is a complete entrance/office mortise lockset with a 3/4 inch latch and a 1 inch deadbolt.
17) We only need a deadbolt on the opening, not a full lockset - what mortise deadbolt is available?
The Sargent 4874 of the 4870 Series is a double cylinder mortise deadbolt with a 2-3/4 inch backset, which is the same backset the Cal-Royal SC8050 uses. Kaba Ilco's 185 Series mortise lock is also a deadbolt function with no handing. The SC8050 combines a 1 inch throw hardened stainless steel deadbolt with a 3/4 inch latch bolt in one lock body, so a standalone deadbolt is the choice only when no latching lever is wanted.
18) Which mortise lock should I specify for a behavioral health or ligature-resistant opening rather than the SC8050?
TownSteel's MRX line is built for that application: the 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 passage-function satin stainless ligature resistant arch trim version. Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant, ADA compliant and satin stainless steel. The Cal-Royal SC8050 uses a conventional lever trim and meets ADA barrier-free requirements but is not a ligature-resistant design.
19) What is the closest alternative if I need a mortise lock body that is field reversible like the Cal-Royal SC8050?
The BEST 45H Series heavy duty mortise lock body in public entrance function is field reversible, and the Falcon MA101 of the MA Series is a Grade 1 heavy-duty mortise passage lock with field reversible operation. The Cal-Royal SC8050 lock body is also field reversible, so hand does not have to be specified when ordering. Note the function difference: the BEST 45H listed here is public entrance and the Falcon MA101 is passage, while the SC8050 is entrance/office.
20) Is there a dormitory or corridor function mortise lock with a deadbolt similar to the Cal-Royal SC8050?
The Sargent 7925 of the 7900 Series is a Grade 1 heavy duty corridor/dormitory exit function mortise lock with rose trim and a single cylinder deadbolt. The Cal-Royal SC8050 carries a 1 inch throw hardened stainless steel deadbolt as well, but in entrance/office function, and its trim is offered in sectional and wide escutcheon designs across fourteen trim codes. Pick the 7925 when the opening needs dormitory exit behavior rather than office toggle locking.
21) I need electrified lock/unlock control on the lever - what takes the place of the Cal-Royal SC8050?
The Schlage L9092EU with 03A trim is a heavy duty mortise lock with an electric lock/unlock outside lever, keyed outside, request to exit, running on 12/24VDC for 1-3/4 inch doors. The Command Access ML190 Series is a heavy-duty motorized mortise lock in storeroom function with field selectable fail-safe or fail-secure operation on 24VDC, and the BEST 45HW Series is a heavy duty wired electromechanical mortise lock with 12V/24V operation. The Cal-Royal SC8050 is mechanical only.
22) Will a cylindrical lock like the Schlage PC10 work where the Cal-Royal SC8050 is specified?
No. The Schlage PC10 of the PC Series is a Grade 1 passage cylindrical lock, non-keyed with rose, for 1-3/4 inch doors, and it uses bored cylindrical door prep. The Cal-Royal SC8050 is a mortise lockset requiring a mortise pocket, a 2-3/4 inch backset and an 8 inch by 1-7/32 inch armor faceplate. The two preps are not interchangeable without new door machining.
23) What mortise lock handles an intruder or lockdown function that the Cal-Royal SC8050 does not?
The BEST 45HCA Series heavy duty mortise lock body is offered in intruder function, and the TownSteel FME-4000 Series is a Grade 1 heavy-duty electronic intruder classroom mortise lockset with RFID for 1-3/4 inch doors. The Cal-Royal SC8050 is an entrance/office function lockset with a toggle button on the inside and does not provide a lockdown function.
24) Does the SC8050 need wiring or power?
No. It is a fully mechanical mortise lockset, no power, no wiring, no batteries. If you want credential or keypad access on the same prep, the electronic options include the BEST 45HW wired electromechanical mortise lock at 12V/24V or the Dormakaba E-Plex 2066 pushbutton keyless mortise lock.
