Sargent 7925 OBL 26D – Frequently Asked Questions

1) Will the Sargent 7925 mortise lock fit a 2-inch thick door?
Yes. The 7925 covers door thicknesses from 1-3/8 inches through 2-1/4 inches, so a 2 inch leaf is inside the range with room either side. That span is wider than most Grade 1 mortise bodies, which is useful on older wood doors that measure under the 1-3/4 inch commercial standard, and on thick institutional or exterior leaves. The backset is 2-3/4 inches, the standard mortise backset, so an existing mortise pocket cut to that centerline lines up.
2) What does the dormitory or exit function on the Sargent 7925 actually do at the door?
It is the corridor/dormitory function: a keyed lever with a separate single cylinder deadbolt. The deadbolt is thrown by key from the outside, and the inside lever retracts both the latch and the deadbolt in one motion so anyone inside always gets out without needing to know the bolt is set. That is why it lands in student housing, apartments, and any room where a locked occupant must still egress freely. If you want the outside face permanently secure with no deadbolt at all, a storeroom function such as the Cal-Royal NM8080 is the different animal.
3) Do I have to order the Sargent 7925 handed, or can one lock cover both left and right doors?
One part covers both. The 7925 is non-handed and field reversible, and the rehanding is done without opening the lockbody case. For a property manager or a facility stockroom that means a single lock on the shelf serves every opening in the building regardless of swing, and there is no wrong-hand return. Contrast that with something like the Baldwin 6310190RRLS, which is ordered as a specific right hand reverse lever.
4) Will the 7925 deadbolt reach into my existing mortise strike?
The 7925 throws a 1 inch latchbolt and ships with a curved lip strike. A 1 inch throw is a full commercial mortise projection, so it seats into a standard ANSI mortise strike prep cut to a 2-3/4 inch backset. The thing to check on a retrofit is the strike lip, not the throw: the curved lip is sized to carry the bolt past the frame stop, and if your existing strike has a flat or shorter lip the bolt can catch on the stop rather than land in the pocket.
5) Can I put the Sargent 7925 on my existing Sargent master key system, or use an interchangeable core?
All three cylinder routes are offered and you pick one on the order. Standard is a 6 pin conventional cylinder. Option 60 takes Sargent Large Format Interchangeable Core (FSIC), and option 0 takes Sargent Small Format Interchangeable Core (SFIC). Keying is specified separately: standard keying, KD keyed different, KA keyed alike, or MK master keyed into an existing system. For a campus or apartment portfolio already running SFIC, the 0 prefix lets your locksmith drop your own cores in and keeps the lock on the system you already control.
6) Is the Sargent 7925 mortise lock approved for a fire rated door opening?
The 7925 is built to ANSI/BHMA Grade 1 and is UL fire tested across all functions in the 7900 line. Grade 1 is the highest ANSI/BHMA operational and security grade, which is what most institutional and government specs call out by name for corridor and stairwell openings. Note that the function itself matters on a fire door: the inside lever retracts the deadbolt, so egress is never defeated by someone throwing the bolt.
7) What is a simpler mortise lock than the Sargent 7925 for a door that does not need to lock?
The Sargent 7925 is a keyed lock with a deadbolt, which is more hardware than a corridor or closet door that only needs to latch. The Hager 3810S is a Grade 1 passage mortise lock with a rose and 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inch, matching the 7925 rose trim approach and its 2-3/4 inch backset. The Falcon MA101 is a Grade 1 heavy duty mortise passage lock in the MA Series that is fire rated and field reversible, the same rehanding convenience the 7925 offers. The Schlage PM010 is a Grade 1 passage latch mortise lock for 1-3/4 inch doors.
8) Which mortise lock should I use instead of the Sargent 7925 on a door thicker than 2-1/4 inches?
The Sargent 7925 accommodates door thicknesses from 1-3/8 inch to 2-1/4 inch. Above that, the Hager 3810E passage mortise lock with escutcheon and 2-3/4 inch backset covers 1-3/4 to 2-1/2 inch, as does the Hager 3850E Grade 1 office mortise lock with lever and escutcheon on the same 2-3/4 inch backset. The Baldwin 6310 entry/storeroom mortise lock body is listed for 1-3/8 inch and over on a 2-1/2 inch backset. Note the Baldwin backset differs from the 7925 2-3/4 inch, so the door prep is not the same.
9) Are the Emtek mortise entrance locksets a substitute for the Sargent 7925?
No. The Sargent 7925 is a keyed Grade 1 commercial mortise lock with a deadbolt. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton, and 3106 Manhattan mortise entrance locksets are all dummy function, meaning they are trim that does not latch or lock. The Schlage L0170 is likewise a Grade 1 mortise dummy trim, non-keyed, for 1-3/4 inch doors. Use those on an inactive leaf or a fixed panel, not on an opening that has to secure.
10) What replaces the Sargent 7925 if the opening needs to be released from an access control system?
The Sargent 7925 is a mechanical keyed mortise lock with no electrical operation. For an access controlled opening, the Schlage L9092EU with the 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 for 1-3/4 inch doors, which is the closest match to the 7925 corridor function. The Command Access ML190 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 is a heavy duty wired electromechanical mortise lock with 12V or 24V operation.
11) Does the Sargent 7925 work on an aluminum storefront door?
The Sargent 7925 is a heavy duty commercial mortise lock for door thicknesses of 1-3/8 inch to 2-1/4 inch with a 2-3/4 inch backset, which is a hollow metal or wood door prep rather than a narrow aluminum stile. For aluminum storefront, the Alarm Lock DL1300NW Trilogy Networx wireless electronic mortise lock is made for Adams Rite deadlatches, and the Dormakaba E-Plex 2066 electronic pushbutton keyless mortise lock is specified for wide stile. The Kaba Ilco BR Series is a glass door bottom rail lock for all-glass openings.
12) If I am standardizing a building on Grade 1 mortise hardware, which locks carry the same grade as the Sargent 7925?
The Sargent 7925 is certified to ANSI/BHMA Grade 1 and UL fire tested. Peers holding Grade 1 across the common functions include the Accentra 8805FL in storeroom, the Corbin Russwin ML2003 in classroom, the Cal-Royal NM8050 office/entrance, NM8070 classroom, NM8080 storeroom, and NM8440 privacy, and the Falcon MA101 passage, which is also fire rated. One to watch when writing the schedule: the Schlage LEBMB-ADD mobile-enabled mortise lock is Grade 2, not Grade 1, though it carries a 3 hour fire rating.
13) What lever styles and finishes does the Sargent 7925 come in, and what size is the rose?
Four lever designs, BB, BJ, BL and BP, all on a 2-3/4 inch round rose (option O). Thirteen finishes are stocked, running from 03 bright brass and 04 satin brass through 10B oil rubbed dark oxidized bronze, 14 and 15 nickel, 20D dark statuary bronze, the workhorse 26D satin chrome, and BSP black or WSP white suede powder coat. If you are matching existing openings in a building, 26D is the common commercial default and the powder coats are the ones to look at for a painted or blackened door package.
14) Should I use a mortise lock like the Sargent 7925 or a cylindrical lockset on a dorm room door?
Go mortise where you want a deadbolt and a latch in one body. The 7925 puts a single cylinder deadbolt and a lever latch in a single mortise pocket, so you get real bolt security without adding a separate deadbolt above the lock. A cylindrical lock such as the Schlage PC10 installs into a simple bored hole and is faster and cheaper to prep, but a bored lockset has no deadbolt in the body. The trade is prep: mortise needs a routed pocket in the door edge, which is why it usually goes into new doors or replaces an existing mortise lock rather than converting a bored one.
15) What are the alternatives to the Sargent 7925 if I need a classroom or storeroom function instead of dormitory?
Same mortise prep, different function. For classroom, the Corbin Russwin ML2003 is Grade 1 mortise classroom for 1-3/4 inch doors, and the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch. For storeroom, look at the Accentra 8805FL Grade 1 with the Arcadia lever, or the Cal-Royal NM8080 which offers an interchangeable core option. Privacy with a deadbolt is the Cal-Royal NM8440. Watch the door thickness on all of those: they are listed at 1-3/4 inches, where the 7925 covers 1-3/8 to 2-1/4.
16) I want keypad or card access on dorm doors instead of keys. What mortise options are there?
The 7925 is a mechanical key lock, so if you want credentials the swap is to an electronic mortise body in the same pocket. TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors. Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE wireless mortise lock with a 125kHz proximity reader, mobile enabled, and a 3 hour fire rating. For pushbutton without a network, Alarm Lock DL3500CR is a Grade 1 electronic mortise with 300 user codes for 1-5/8 to 1-7/8 inch doors. All of those narrow the door thickness range against the 7925.
17) The Sargent 7925 has a deadbolt - what else gives me a deadbolt in a mortise lock?
The Sargent 7925 is a single cylinder keyed mortise lock with a deadbolt. If the deadbolt is the point and keys are not, the Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad for doors 1-5/8 to 1-7/8 inch. The Kaba Ilco 185 Series is a no-handing mortise deadbolt function lock. For a privacy application rather than a keyed one, the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with a deadbolt for 1-3/4 inch doors.
18) Is there a Grade 1 mortise lock like the Sargent 7925 that uses a keypad instead of keys?
The Sargent 7925 is a keyed mortise lock taking a 6 pin standard cylinder, a Sargent large format interchangeable core, or a Sargent small format interchangeable core. For credential-based access instead, 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, and the Dormakaba E-Plex E5086 is a Grade 1 electronic pushbutton and card entry/egress mortise lock. The TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors. These change the credential and the door thickness range, so verify the door before swapping.
19) I need a complete mortise lock, not just a lock body - how does the Sargent 7925 compare to the BEST 45H?
The Sargent 7925 ships as a mortise lock with rose trim and lever, in 2-3/4 inch rose and BB, BJ, BL, or BP lever styles. The BEST 45H is a heavy duty mortise lock body with public entrance function and field reversible operation, and the BEST 45HCA is a heavy duty mortise lockbody with intruder function, both supplied as lock bodies. The Baldwin 6301 and 6301LS are also mortise lock bodies, in entrance/apartment function on a 2-1/2 inch backset for doors 1-3/4 inch and over, with the 6301 prepped knob by knob and the 6301LS lever by lever. If the order needs trim included, the body-only parts require it specified separately.
20) Can I use a cylindrical lock instead of the Sargent 7925 mortise lock?
Not without changing the door prep. The Sargent 7925 requires a mortise pocket in the door edge. The Schlage PC10 is a Grade 1 passage cylindrical lock with rose for 1-3/4 inch doors, and it uses a bored cylindrical prep instead. A cylindrical lock will not fill a mortise pocket, and a mortise lock will not fit a bored door without new preparation, so the swap only works if the door is being prepped fresh or the existing prep already matches.
21) Which Grade 1 mortise lock covers an office or entrance opening rather than the Sargent 7925 dormitory function?
The Sargent 7925 is corridor/dormitory function. The Cal-Royal NM8050 is a heavy duty Grade 1 office/entrance mortise lockset with an auxiliary deadlatch for 1-3/4 inch doors. The Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon, non-keyed, on a 2-3/4 inch backset for 1-3/4 to 2-1/2 inch doors, so it suits an office door where the lever trim is not keyed. The Baldwin 6310190RRLS is a right hand reverse entry/storeroom lever by lever mortise lock on a 2-1/2 inch backset for doors 1-3/8 inch and over; unlike the field reversible 7925, it is supplied handed.
22) What is the difference between the Sargent 7925 and the Cal-Royal NM8440 for a bedroom or bathroom door?
Both are Grade 1 mortise locks with a deadbolt, but the function differs. The Sargent 7925 is a keyed single cylinder corridor/dormitory lock, so a key operates it from outside. The Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with a deadbolt for 1-3/4 inch doors, intended for bed and bath openings where the occupant secures the door from inside. The 7925 also covers a wider door range, 1-3/8 inch to 2-1/4 inch.
23) Is the Sargent 7925 heavy duty enough for a high traffic student housing or hospital corridor?
It is rated heavy duty for commercial use, with a stacked steel deadbolt assembly behind the 1 inch throw. Stacked steel is the construction that takes the abuse in dorm and multifamily corridors, where doors get slammed and levers get hung on. Grade 1 is the specification level institutional facilities standardize on, and with 21 functions in the 7900 family you can carry one lock body style and one keying system across an entire building.
24) Does the Sargent 7925 come with a lever, or do I order the trim separately?
Trim is included and configured on the order. The 7925 is a rose trim lock: you pick the lever design (BB, BJ, BL or BP), the 2-3/4 inch O rose, the finish, the cylinder type, and the keying, and it ships as that combination. What you specify separately is your keying detail if it is going onto an existing master system, and the cores themselves if you are running Sargent SFIC or FSIC and want to install your own.
