Sargent 7804-OB-26D – Frequently Asked Questions

1) What does the storeroom function on the Sargent 7804 mortise lock actually do at the door?
Outside knob stays locked all the time on the 7804. A key retracts the latchbolt from outside, and the inside knob always retracts it for free egress. Nobody can leave the outside knob unlocked by accident, which is why storeroom is the usual pick for supply rooms, electrical and mechanical rooms, and any door that has to stay secure without staff thinking about it. If you need the outside knob to be lockable and unlockable with a key instead, storeroom is the wrong function.
2) Is the Sargent 7804 mortise lockset approved for a fire-rated door?
Yes. The 7800 Series lock body is UL and cUL listed and carries ANSI/UL 10C positive pressure fire test certification, so it can go on a labeled fire door assembly. It is also listed for windstorm applications. The latch is a one-piece anti-friction reversible latch with an auxiliary deadlatch, which is what keeps it latching under the positive pressure a fire test puts on the door.
3) Will the Sargent 7804 drop into an existing mortise pocket and strike prep?
The 7804 uses an 8 x 1-1/4 inch front and a 1 x 5/8 inch latch, with a 1-1/4 inch strike lip. That is the standard ANSI mortise face, so it goes into a door already routed for an 8 x 1-1/4 inch mortise lock without new pocket work. Measure your existing front before you order: if the door was prepped for a shorter or narrower face, the pocket and the face cutout both have to be reworked.
4) Do I need to order handing for a Sargent 7804 mortise lock?
No handing to specify on the 7804 lock body. The latch is a one-piece reversible anti-friction latch, so the same lock works left or right hand. That matters if you are stocking spares for a building with doors swinging both ways, one part number covers all of them.
5) I need this keyed into our existing master key system. Which Sargent 7804 should I order?
Order the 7804-OB-LC, less cylinder. You get the storeroom lock body plus the O-rose and B-knob trim, and your locksmith drops in a mortise cylinder keyed to your system. If you are not tied to an existing system, the 7804-OB comes with a Sargent LA keyway cylinder already in it.
6) Is the Sargent 7804 Grade 1, and what does that mean for a high-traffic door?
ANSI/BHMA A156.13 Series 1000, Operational Grade 1 and Security Grade 1. Grade 1 is the top commercial tier and the level normally written into institutional and government specs, so the 7804 satisfies a spec calling for a Grade 1 mortise storeroom lock. It is a commercial-duty lock, not a residential one.
7) I want a lever instead of a knob for ADA. What storeroom mortise lock should I look at?
The 7804 is a knob lockset (B-knob on O-rose), so it is not the part for a lever opening. For a Grade 1 storeroom mortise lock with a lever, the Accentra 8805FL uses an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option. Both are storeroom function like the 7804.
8) What is the closest Grade 1 storeroom mortise lock to the Sargent 7804 if Sargent is not an option?
The Accentra 8805FL is the nearest equivalent: a Grade 1 mortise lock in storeroom function, from the Accentra 8800 Series, supplied with the Arcadia lever. The Sargent 7804 is also a Grade 1 mortise lock in storeroom function, so the security grade and the keyed-outside-always-locked behavior line up. The difference is the trim style at the door - the 7804 is offered with a B-knob on an O-rose, while the 8805FL comes with a lever. On an opening that has to meet ADA operable-hardware requirements, a lever trim is the one that applies.
9) Which Grade 1 storeroom mortise lock takes an interchangeable core?
The Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset offered with an interchangeable core option, fitted to 1-3/4 inch doors. The Sargent 7804 is a Grade 1 storeroom mortise lock ordered either as a bare body, with an LA keyway cylinder, or less cylinder for keying in the field. If a facility is standardized on an IC keying system and wants the core dropped in at the door, the NM8080 is built around that; if the site keys to Sargent LA, the 7804 is the one that stays in the existing system.
10) I need a classroom function mortise lock, not storeroom - what should I order instead?
Storeroom function keeps the outside trim locked at all times with the key retracting the latch, which is wrong for a classroom where the teacher needs to lock and unlock the outside lever from the key. The Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset from the ML2000 Series for 1-3/4 inch doors, and the Cal-Royal NM8070 is a heavy duty Grade 1 classroom mortise lockset for 1-3/4 inch doors. Both keep the mortise case prep identical to a storeroom lock; only the function differs.
11) Is there an electronic mortise lock with storeroom function for a door that needs access control?
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, so the outside trim is controlled by the access control system rather than only by key. The Sargent 7804 is a mechanical Grade 1 storeroom mortise lock, keyed outside with the inside trim always free. Choose the mechanical 7804 where there is no power or credential reader at the opening, and the ML190 where the door has to be released remotely or tied into a card system.
12) Can I use a Baldwin 6310 in place of a Sargent 7804 storeroom mortise lock?
They are not interchangeable on a commercial opening. The Baldwin 6310 is an entry/storeroom mortise lock body, knob by knob, on a 2-1/2 inch backset for doors 1-3/8 inch and over. The Sargent 7804 is a Grade 1 mortise lock certified to ANSI/BHMA A156.13 Series 1000 with UL and cUL listing for fire doors. If the opening carries a fire label or a Grade 1 requirement on the spec, the 7804 is the one that answers it; the Baldwin is an ornamental-side product on a different backset, so the door prep does not carry across either.
13) What is a mortise storeroom lock better for than a cylindrical lock on a commercial door?
A mortise lock like the Sargent 7804 sits in a pocket routed into the door edge with an 8 x 1-1/4 inch face, which gives you a bigger, stiffer lock case and a Grade 1 security rating on a door that gets hammered. A cylindrical lock, like the Schlage PC10, goes through a bored hole instead and is quicker to install and easier to retrofit into a residential-style prep. Pick mortise when the door is already mortise-prepped or the spec calls for it; pick cylindrical when the door has a standard 161 bore and you do not want to rout the edge.
14) We need card or keypad access on this door instead of a key. What replaces a Sargent 7804 mortise lock?
Swap to an electronic mortise lock that uses the same mortise pocket. For standalone keypad, the Alarm Lock DL3500CR Trilogy is Grade 1 and holds 300 user codes, and the Dormakaba E-Plex E5086 is a Grade 1 pushbutton/card mortise lock. For credential-based access, the TownSteel FME-2000 is a Grade 1 heavy duty mortise lockset with RFID. Note the functions differ: the DL3500CR is classroom function, not storeroom, so confirm the function matches how you want the outside trim to behave. If you want storeroom function with electric control, the Command Access ML190 is a heavy-duty storeroom motorized mortise lock with field selectable EL/EU on 24VDC.
15) Can I buy just the Sargent 7804 mortise lock body to replace a failed case and keep my existing trim?
Yes, the plain 7804 is sold as body only, no trim, no cylinder. That is the right order when the knobs and roses on the door are fine and the case has worn out. It is storeroom function, so confirm the case you are pulling out was storeroom too, otherwise the door will behave differently after the swap.
16) We are standardizing a facility on Grade 1 mortise locks. What other functions pair with the Sargent 7804 storeroom?
For a mixed facility you generally need storeroom on secure rooms, classroom on teaching and patient rooms, privacy on restrooms, and passage on corridor doors. Alongside the 7804 storeroom, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset, the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt, and the Schlage PM010 is a Grade 1 non-keyed passage mortise lock. Keeping every opening on a mortise prep means one door prep and one spare-parts list across the building.
17) What is a simpler non-keyed mortise lock for a door that does not need to be locked?
For a corridor or closet door that only needs to latch, 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 with field reversible operation and a fire rating. Neither takes a cylinder. The Sargent 7804 is a keyed storeroom lock, so it is the wrong choice where nothing is being secured and no keying is wanted.
18) What mortise lock should I use for a restroom or bedroom door instead of a storeroom lock?
A storeroom lock like the Sargent 7804 has no inside locking, so it will not do for a restroom. The Cal-Royal NM8440 is a heavy duty Grade 1 privacy mortise lockset with a deadbolt for 1-3/4 inch doors, and the Hager 3840S is a Grade 1 privacy mortise lock on a 2-3/4 inch backset for doors 1-3/4 inch to 2 inch. Confirm the backset against the existing door prep before swapping in either one.
19) Is there a keypad mortise lock that still takes a key override, as an alternative to a keyed storeroom lock?
The BEST 45HZ EZ Series is an electronic keypad mortise lock with key override, and the Accentra NTM623-NR nexTouch Generation 3 mortise lock uses a capacitive touchscreen keypad with cylinder override and no deadbolt. Both let staff enter on a code while keeping a mechanical key as backup. The Sargent 7804 is key-only on the outside with the trim locked at all times, which suits a stockroom where codes are not wanted and nothing needs batteries.
20) Which mortise lock do I use for a door that must stay unlocked during business hours but lock after?
A storeroom function like the Sargent 7804 keeps the outside trim locked at all times, so it cannot be left unlatched for the public. For an office or entrance opening that gets toggled, the Cal-Royal NM8050 is a heavy duty Grade 1 office/entrance mortise lockset with auxiliary deadlatch for 1-3/4 inch doors, and the BEST 45HCAC is a heavy duty public entrance mortise lock body with field reversible operation. Both keep the same mortise pocket, so the change is the function, not the door prep.
21) For a behavioral health or detention opening, is a Sargent 7804 an acceptable mortise lock?
Not where ligature resistance 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, the MRX-A-01 is the same grade in a 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. The Sargent 7804 is a Grade 1 storeroom lock with knob trim, which is a standard commercial trim rather than a ligature-resistant one.
22) What finish does the Sargent 7804 come in, and will it match the rest of our building hardware?
26D, satin chromium plated over nickel, across all three 7804 configurations. That is the standard satin chrome you see on most commercial openings, so it lines up with satin chrome exit devices, closers, and hinges already on the doors. If your building is standardized on a bronze or brass finish, this is not the match.
23) Is there a Sargent 7804 install guide and catalog I can pull dimensions and templates from?
Sargent publishes the 7800/8200 Mortise Lock Catalog for the full series, plus a full line catalog, and an installation guide covering the 7800 mortise lock with PT paddle trim. Those carry the door prep templates and the complete function and trim tables, which is what you want in hand before routing a door.
24) An Emtek 3104 mortise entrance lockset looks similar - will it work as a storeroom lock?
No. The Emtek 3104 Hamilton and the 3102 Memphis are dummy function mortise entrance locksets, which means the trim is fixed and there is no latch operation or keying at all. They are used on inactive leaves for appearance. The Sargent 7804 is a Grade 1 keyed storeroom mortise lock with a one-piece anti-friction reversible latch and auxiliary deadlatch, so it actually secures the opening.
25) Does the Sargent 7804 need a separate deadbolt, or is there a mortise deadbolt alternative?
The Sargent 7804 is a storeroom latch lock with a one-piece anti-friction reversible latch and auxiliary deadlatch, keyed from outside. If the opening needs a throw bolt instead, the Kaba Ilco 185 Series is a mortise deadbolt with no handing, and the Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with a privacy keypad and 2,000 user codes for doors 1-5/8 inch to 1-7/8 inch thick. A deadbolt is a separate mortise pocket from a lockset, so plan the door prep accordingly.
