Cal-Royal NM8080-SS-RH-US26D – Frequently Asked Questions

1) What does storeroom function mean on the Cal-Royal NM8080, and is it right for a mechanical room or supply closet?
Storeroom function (F07) is exactly what a locked storeroom or mechanical room wants. The outside lever is always inoperative, so the door is locked at all times from the corridor side and only a key retracts the latch. The inside lever is always free, so anyone inside walks out without a key. Nothing to remember to lock, nothing that can be left unsecured by accident.
2) Can the Cal-Royal NM8080 be used on a fire-rated door?
Fire rated, yes. The NM8080 is UL Listed with an "A" Label 3-hour rating for use on fire doors, single or pair, and the strike carries the "F" mark stamped on it. The description ties it to UL10C and UBC 7-2-1997. That covers stair doors, corridor doors, and rated storeroom openings without a separate fire-rated substitution.
3) Do I have to order the Cal-Royal NM8080 handed, or can I flip it in the field?
Order either hand and don't lose sleep over it. The NM8080 comes as Left Hand or Right Hand, but the lock is field reversible, so a lever that arrives on the wrong hand gets turned around on site. It uses individual springs on each lever to stop lever sag, which is the usual failure on a reversible lock that gets leaned on all day.
4) Will the Cal-Royal NM8080 work with my existing mortise strike, or do I need to cut the frame?
The lockset ships with a brass, non-handed curved strike measuring 4-7/8 x 1-1/4 inches, which is the standard ANSI mortise strike footprint, so it drops into an existing ANSI-prepped frame. A curved-up strike is available on request if the frame prep calls for it. The deadbolt throws 1 inch, so the frame pocket behind the strike has to be deep enough to take that.
5) Does the Cal-Royal NM8080 take an interchangeable core, and what keyway does it ship with?
Standard is a 6-pin solid brass "C" keyway cylinder, single cylinder keyed. An interchangeable core version is available if you're keying into an existing IC system, and electrified versions of the lock are offered as well. Say which one you need at the order, because the standard build is the fixed cylinder.
6) Is the Cal-Royal NM8080 heavy duty enough for a school or hospital corridor?
It's a Grade 1 lock and it's built for that traffic. The NM8080 meets ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1, with the lock body conforming to Federal Specification Type 86, and it's tested past 1,000,000 cycles. The case is heavy gauge zinc chromate steel with a wrought brass armored front, and the forged brass levers exceed ADA requirements for operation. That's the specification an institutional facility standardizes on.
7) I need a mortise lock for a classroom, not a storeroom. What should I use instead of the Cal-Royal NM8080?
The NM8080 is storeroom function only, so it's wrong for a classroom where a teacher needs to lock and unlock the outside lever. For classroom function in a Grade 1 mortise on a 1-3/4 inch door, the Corbin Russwin ML2003 is the mechanical option. If you want a classroom lock with an inside-visible security indicator, the Marks USA LA318GJ is a Grade 1 indicator mortise lockset, also for 1-3/4 inch doors. TownSteel's FME-2000 Series is the Grade 1 classroom mortise with RFID credentials if the facility is moving to cards.
8) Will the Cal-Royal NM8080 fit a door prepped for a Baldwin 6310 mortise lock?
No, not without reworking the prep. The Baldwin 6310 storeroom mortise body is a 2-1/2 inch backset lock. The NM8080 is 2-3/4 inch backset, so the cylinder, lever, and case pocket land in different places on the door. If you're replacing a 2-1/2 inch backset mortise body and want to reuse the existing prep, stay with a 2-1/2 inch backset lock.
9) What is the closest Grade 1 storeroom mortise lock to the Cal-Royal NM8080?
The Accentra 8805FL from the 8800 Series is the closest straight equivalent: it is a Grade 1 mortise lock in storeroom function, the same grade and same function as the NM8080. The NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors on a 2-3/4 inch backset, so on an opening already prepped for a standard mortise storeroom lock the two answer the same requirement. The 8805FL comes with the Arcadia lever; the NM8080 is ordered with either SE escutcheon trim or SS sectional trim in six finishes.
10) I need a keyed mortise lock but the room has to stay unlocked for classroom use - what should I order instead of the NM8080?
Look at the Corbin Russwin ML2003 from the ML2000 Series, a Grade 1 mortise classroom lockset for 1-3/4 inch doors. The NM8080 is a storeroom-function lock: the outside lever is always inoperative and entry is by key only, so it cannot be left in an unlocked state for a class period. The ML2003 is built for classroom function on the same 1-3/4 inch door thickness the NM8080 covers.
11) Can I use a Sargent 4874 mortise deadbolt in place of the NM8080?
No - they do different jobs. The Sargent 4874 from the 4870 Series is a double cylinder mortise deadbolt on a 2-3/4 inch backset, meaning it is key-operated from both sides with no latch and no lever. The NM8080 is a storeroom lockset: it has a latchbolt operated by key from outside or by the inside lever, with the inside lever always free for immediate egress. Backset alone matching does not make the 4874 a substitute; a deadbolt with no inside lever will not give you the egress behavior a storeroom lockset provides. The Kaba Ilco 185 Series is likewise a deadbolt function, not a lockset.
12) I need the storeroom lock to be electrically controlled from an access control panel - what takes the place of the NM8080?
The Command Access ML190 Series ML19092-M is a heavy-duty motorized mortise lock in storeroom function with field selectable EL/EU operation and 24VDC power - the same storeroom function as the NM8080 but under panel control. The Schlage L9092EU 03A is a heavy-duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit and 12/24VDC operation, for 1-3/4 inch doors. The NM8080 itself is a mechanical, non-electronic lockset.
13) Is the Schlage LEBMB-ADD an equal-grade swap for the NM8080 on a fire door?
Not on grade. The Schlage Electronics LEBMB-ADD from the LE Series is a Grade 2 mobile-enabled mortise lock with push button and LED for 1-3/4 inch doors, carrying a 3 hour fire rating, in privacy, office and apartment functions. The NM8080 is Grade 1 to ANSI/BHMA A156.13 Series 1000 and exceeds 1,000,000 cycles. Both are 3-hour fire rated on a 1-3/4 inch door, so if your spec calls for Grade 1 the NM8080 meets it and the LEBMB-ADD is written to Grade 2.
14) Does the Cal-Royal NM8080 have a deadbolt, or just a latch?
Both. There's a 1 inch throw brass, chrome-plated deadbolt with hardened steel rollers and anti-saw hardened pins, plus a separate heavy-duty latchbolt with an auxiliary latch that deadlocks the latchbolt when the door closes. The auxiliary latch is what stops a card or shim getting past the latch, and the anti-saw pins are what stop a blade getting through the deadbolt.
15) What finishes does the Cal-Royal NM8080 mortise lockset come in, and can I match the other doors in my building?
Six finishes across both hands and both trim styles: US3 polished brass, US4 satin brass, US10B antique bronze oiled, US26 polished chrome, US26D satin chrome, and US32D satin stainless steel. US26D and US32D are the two that match most existing commercial hardware, so a property manager standardizing a building will usually land on one of those.
16) I need keyless or card access on a storeroom door instead of a keyed mortise lock. What are my options?
The NM8080 is a keyed mechanical mortise, no electronics in the standard build. If you want to drop the keys entirely on a mortise prep, Dormakaba's E-Plex 2066 Series is an electronic pushbutton keyless mortise lock, and the PowerPlex P2066 Series is the self-powered version. For credential-based access, the Schlage CO-100 is a standalone electronic mortise with a keypad reader for 1-3/4 inch doors, and the Schlage LEMD ENGAGE Series is a Grade 1 wireless mortise with a 125kHz proximity reader. Note the function differs on each, so check that the one you pick locks the way a storeroom needs to.
17) Is the Cal-Royal NM8080 ADA compliant for lever operation?
The forged brass lever handles are built to exceed ADA requirements, and the lockset is stated to meet ADA regulations. That matters on the inside lever in particular, since storeroom function leaves it free for egress and it has to be operable without tight grasping or twisting.
18) Does the Cal-Royal NM8080 meet Buy American Act requirements for a government job?
Yes, the NM8080 is stated to meet the Buy American Act, and the lock body conforms to Federal Specification Type 86. Between that and the ANSI/BHMA A156.13 Grade 1 listing, it's the spec set a municipal or federal facility submittal usually asks for on a storeroom opening.
19) The door does not need to be keyed at all - what mortise lock replaces the NM8080 on a corridor or closet door?
Two non-keyed mortise options fit the same 1-3/4 inch door. The Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, for 1-3/4 inch doors. The Falcon MA101 from the MA Series is a Grade 1 heavy-duty mortise passage lock with field reversible operation and a fire rating. The NM8080 is keyed with a single-cylinder keyed function, so on an opening where nothing needs to lock, a passage lock body is the part that matches the use.
20) Which mortise lock do I use if I want a keypad or credential instead of a key on a storeroom door?
The Cal-Royal NM8080 is a mechanical lock and is not electronic; entry is by a 6-pin solid brass C keyway cylinder. For credential-based entry on a mortise prep, the TownSteel FME-2000 Series is a Grade 1 heavy-duty mortise lockset with RFID technology for 1-3/4 inch doors, the same door thickness the NM8080 is built for. The BEST 45HZ EZ Series is an electronic keypad mortise lock with key override. Note that the FME-2000 is a classroom-function lock, not storeroom, so confirm the function matches how the room is used.
21) Is the Emtek 3106 Manhattan mortise entrance lockset an alternative to the NM8080?
It is not. The Emtek 3106 Manhattan is a dummy function mortise entrance lockset - dummy trim does not latch or lock at all. The same applies to the Emtek 3104 Hamilton, 3102 Memphis and 3019 Brisbane, all dummy function, and to the Schlage L0170 half dummy trim in the L Series. The NM8080 is a keyed storeroom lockset with a 1 inch throw deadbolt and a deadlocking auxiliary latch. Dummy trim is for the inactive leaf of a pair or a decorative pull; it will not secure a storeroom.
22) My doors are 1-5/8 to 1-7/8 inch thick - will the Cal-Royal NM8080 work, and what fits if not?
The NM8080 is built for 1-3/4 inch thick doors. If your openings vary across a 1-5/8 to 1-7/8 inch range, the Alarm Lock DL3500CR from the DL3500 Series is a Grade 1 electronic mortise lock rated for 1-5/8 to 1-7/8 inch doors, as is the DL2700CR from the DL2700 Series - both are classroom function rather than storeroom. On the mechanical side, the Hager 3810E in the 3800 Series covers 1-3/4 inch to 2-1/2 inch doors on a 2-3/4 inch backset, though it is a passage function.
23) I only need to replace the mortise lock body, not the trim - what are my options versus the NM8080?
The NM8080 ships as a complete lockset with lever trim and escutcheon or sectional trim, plus a brass non-handed curved strike measuring 4-7/8 inch by 1-1/4 inch. If the existing trim is staying on the door, the BEST 45H Series 45HCAC is a heavy-duty mortise lock body in public entrance function with field reversible operation, and the 45HCAINL is a heavy-duty mortise lockbody with intruder function. The Baldwin 6310 is a mortise lock body in entrance/storeroom function on a 2-1/2 inch backset - closest to the NM8080 in intent, but check that backset against your door prep, since the NM8080 is 2-3/4 inch.
24) Which Grade 1 mortise lock should I use on a behavioral health or patient room instead of the NM8080?
For anti-ligature openings the TownSteel MRX-L-01 is a Grade 1 heavy-duty anti-ligature lever mortise lockset in stainless steel for 1-3/4 inch doors, and the MRX-A-01 is the ligature resistant arch trim version, also Grade 1 heavy duty for 1-3/4 inch doors - both passage function. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant in satin stainless steel. The NM8080 uses forged brass lever handles built to exceed ADA requirements, so it meets ADA but carries a conventional lever rather than a ligature-resistant profile.
25) What is the difference between the NM8080 and the Sargent 7925 dormitory lock for a dorm corridor door?
The Sargent 7925 from the 7900 Series is a Grade 1 heavy-duty mortise lock in corridor/dormitory exit function with rose trim and a single cylinder deadbolt. The NM8080 is Grade 1 in storeroom function with a 1 inch throw chrome-plated brass deadbolt and single cylinder keyed function, and its outside lever is always inoperative with key entry only. On a dorm room door where an occupant needs to throw the deadbolt from inside, the 7925 dormitory exit function is the one built for that; the NM8080 storeroom function is aimed at doors that stay locked to the outside at all times.
26) I need a wireless mortise lock that reports back to an access system - what is the option alongside the NM8080?
The Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader, mobile enabled, with a deadbolt and LED, Greenwich trim, right hand, and a 3 hour fire rating. The Alarm Lock DL1300NW Trilogy Networx is a wireless electronic mortise lock with a keypad, built for Adams Rite deadlatches. The NM8080 matches the LEMD-GRW on Grade 1 and on fire rating - it is UL Listed A Label 3-hour for single or pair fire doors - but it is a mechanical lock with a 6-pin C keyway cylinder and no reporting.
27) The opening is an aluminum storefront door - can I fit the Cal-Royal NM8080?
The NM8080 is designed for 1-3/4 inch thick doors with a 2-3/4 inch backset and a 8 inch by 1-1/4 inch armored front, which suits standard commercial wood and hollow metal doors rather than narrow aluminum stiles. For glass and aluminum openings the Kaba Ilco BR Series is a glass door bottom rail lock, and the Dormakaba E-Plex E2066 in the E-Plex 2000 Series is an electronic pushbutton keyless mortise lock built for wide stile. Confirm the stile width on your storefront before choosing.
28) Is the Cal-Royal NM8080 lock case going to corrode in a damp mechanical room or exterior vestibule?
The lock case is heavy gauge zinc chromate steel, described as rust-proof construction, with an 8 x 1-1/4 x 3/32 inch steel front and a wrought brass armored front attached by machine screws that conceals the mounting screws. The deadbolt, latchbolt, guardbolt, and stopworks are brass, chrome-plated. That's a brass-and-plated-steel build rather than raw steel, which is what you want in a damp interior space.
