Sargent 8227 LE1A 26D – Frequently Asked Questions

1) Will the Sargent 8227 mortise lock fit a 1-3/4 inch door with a 2-3/4 inch backset prep?
That is exactly the prep it is built for. The Sargent 8227-ET is specified for 1-3/4 inch door thickness with a 2-3/4 inch backset, which is the standard commercial mortise pocket on hollow metal and solid core wood doors. Latchbolt throw is 3/4 inch.
2) What does the 8227 closet/storeroom function actually do at the door?
Storeroom function: the outside lever is always locked and the key retracts the latchbolt for entry. The inside lever always retracts the latch for free egress. The 8227 is a single cylinder lock with a deadbolt, so the key also throws and retracts the deadbolt from outside for a storeroom, closet, or supply room you want dead-locked when unoccupied.
3) Do I have to specify handing when I order the Sargent 8227 mortise lock?
No. The 8227 lock body is field reversible, so handing can be changed on site. That means one part number covers left and right hand openings, which is why a property manager or maintenance shop can stock one lock for a whole building instead of two.
4) Can I use the Sargent 8227 on a fire rated door?
Yes. The 8227 is UL 10C fire rated up to 3 hours, carries ANSI/BHMA A156.13 Series 1000 Operational Grade 1, and is ADA compliant, which covers the usual requirements for a rated stair or storage door in a school, hospital, or office building.
5) Can I get the Sargent 8227 keyed into my existing building master key system?
Yes. The 8227 works with all SARGENT key systems, including Degree, Signature, KESO, and XC, in 6 pin or 7 pin cylinders. When you order you pick the cylinder route: standard cylinder, less cylinder, 70 prep for small format interchangeable core less core, or 60 prep for large format interchangeable core less core. Keying is then set as keyed different, keyed alike, or to a specific key code you supply. If you run SFIC across the property, order the 70 prep and drop your own cores in.
6) What is the closest Grade 1 storeroom mortise lock alternative to the Sargent 8227-ET?
The Accentra 8805FL is the nearest match on function and rating: it is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever. The Sargent 8227-ET is also Grade 1 with a closet/storeroom function, but it is the deadbolt version with escutcheon trim, so if the opening needs a separate throw-and-hold deadbolt in the same lock body, stay with the 8227-ET. Cal-Royal's NM8080 is another Grade 1 storeroom mortise lockset for 1-3/4 inch doors, offered with an interchangeable core option.
7) I need a classroom function instead of storeroom - what mortise lock takes the same kind of opening?
The Sargent 8227-ET is built as a closet/storeroom function, so it will not give classroom keyed control of the outside lever. For classroom openings, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors, and the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch, also for 1-3/4 inch doors.
8) I need the outside lever to unlock electrically on an access control system - what replaces the 8227-ET?
The 8227-ET is a mechanical, key-operated lock with no electrical option. For access control, the Schlage L9092EU electric lock/unlock outside lever mortise lock is heavy duty, keyed outside, with request-to-exit and 12/24VDC operation, and the Command Access ML190 is a heavy-duty motorized storeroom-function mortise lock with field selectable EL/EU operation on 24VDC. The BEST 45HW is a wired electromechanical mortise lock with 12V/24V operation.
9) Is a Baldwin 6310 mortise lock a substitute for the Sargent 8227-ET?
Not a direct one. The Baldwin 6310 entry/storeroom mortise lock body uses a 2-1/2 inch backset and covers doors 1-3/8 inch and over, while the Sargent 8227-ET is built on a 2-3/4 inch backset for 1-3/4 inch doors. The backset difference means different door prep, so a Baldwin body will not drop into a pocket cut for the 8227-ET.
10) My door is 1-5/8 inch thick - can I still use the Sargent 8227-ET?
The Sargent 8227-ET is specified for 1-3/4 inch door thickness. For a thinner leaf, the Alarm Lock Trilogy series covers 1-5/8 inch to 1-7/8 inch: the DL2700CR is a Grade 1 classroom function electronic mortise lock with weatherproof design, the DL3500CR is Grade 1 classroom with 300 user codes, and the DL4500 is a Grade 1 electronic mortise deadbolt. Note those are electronic and their functions differ from a keyed storeroom lock.
11) What do I have to choose besides the finish on a Sargent 8227-ET?
Four things. Escutcheon style (LE1, LS, LW1 or WT), lever design (A, B, E, F, J, L or W, plus P), finish, and the cylinder/keying combination. Finishes run from 03 bright brass and 04 satin brass through 26D satin chrome and 32D satin stainless to BSP black and WSP white suede powder coat, so matching existing openings in a building is usually possible.
12) Is the 8227 an escutcheon trim lock or rose trim, and does that change the door prep?
The 8227-ET ships with escutcheon trim, a full plate behind the lever rather than a small round rose. Sargent publishes one template covering 7800 and 8200 Series mortise locks with all sectional rose trims and escutcheon trims, so the lock body pocket is common; the trim choice affects the face of the door, not the mortise itself.
13) How durable is the Sargent 8200 mortise lock for a high traffic opening?
Heavy duty, and tested well past the usual commercial bar: Sargent completed UL's Cycle Above and Beyond test at 16 million cycles (Verification ID V584148). For a school corridor, hospital storage room, or multi-tenant service door where the lock gets hit all day, that is the reason to spend on a mortise body rather than a cylindrical lockset.
14) I need a storeroom mortise lock but not the deadbolt. What else is there?
The 8227 is the deadbolt version. If a latch-only storeroom lock is enough, the Accentra 8805FL is a Grade 1 storeroom mortise lock with the Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 heavy duty storeroom mortise lockset with an interchangeable core option, listed for 1-3/4 inch doors. Both cover the same lock-outside, free-egress-inside behavior without the separate bolt.
15) Is the Sargent 8227 electronic, and what should I look at if I want keypad or credential access instead?
No, the 8227 is a mechanical key-operated lock with no electronics. For credential or code access on a mortise prep, the TownSteel FME-2000 Series is a Grade 1 RFID mortise lockset for 1-3/4 inch doors, the Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating, and the Dormakaba E-Plex 2066 is a pushbutton keyless mortise lock.
16) Can I standardize on the Sargent 8200 body across a building and just change functions per door?
Yes, that is the point of the 8200 platform. The same multi-functional lock body is available in 56 different functions, including electromechanical, security, and monitoring versions, and functions can be switched. So classroom, office, and storeroom openings across a campus share one body, one door prep, one template, and one keyway.
17) My opening is prepped for a Corbin Russwin ML2000 or a Schlage L Series. Does that help me here?
Do not assume a drop-in. The 8227 is specified for 1-3/4 inch doors on a 2-3/4 inch backset, and Corbin Russwin ML2003 Grade 1 classroom mortise locks are also listed for 1-3/4 inch doors, but cross-brand mortise pocket, faceplate, and trim prep differ and none of that interchange is stated for these parts. Verify the existing pocket and faceplate cut against the Sargent 7800/8200 template before committing.
18) What if I need a privacy or office function mortise lock rather than the storeroom 8227-ET?
The 8227-ET is keyed, single cylinder, closet/storeroom. For a bed/bath privacy opening, the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with 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 an office opening, the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with auxiliary deadlatch and the Hager 3850E is a non-keyed office mortise lock with lever and escutcheon.
19) Can I use a keypad or credential mortise lock instead of keying the Sargent 8227-ET?
Yes, if you want to drop keys on the opening. The 8227-ET is a mechanical lock that takes a cylinder and works with Sargent key systems. Electronic mortise alternatives include the Alarm Lock DL3500CR Trilogy Grade 1 with 300 user codes, the BEST 45HZ EZ Series keypad mortise lock with key override, and the TownSteel FME-2000 Grade 1 mortise lockset with RFID for 1-3/4 inch doors. These change the credential, not the door prep concept - confirm function, since the DL3500CR and FME-2000 are classroom function rather than storeroom.
20) What looks like an alternative to the 8227-ET but will not actually lock the door?
Dummy and passage trims. The Schlage L0170 is a Grade 1 mortise half dummy trim, the Emtek 3102 Memphis and 3104 Hamilton mortise entrance locksets are dummy function, and the Falcon MESC600DT is a dummy escutcheon lever trim. Passage devices such as the Falcon MA101 Grade 1 mortise passage lock and the Schlage PM010 Grade 1 passage latch mortise lock latch but do not key. The Sargent 8227-ET is a keyed single cylinder storeroom lock with a deadbolt, so none of these cover the same duty.
21) For a behavioral health or ligature-resistant opening, what should I specify instead of the Sargent 8227-ET?
The Sargent 8227-ET uses standard lever trim on an escutcheon, which is not a ligature-resistant profile. TownSteel offers the MRX-L-01, a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset, and the MRX-A-01 with satin stainless ligature-resistant arch trim, both passage function for 1-3/4 inch doors. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant in satin stainless steel.
22) I only need a mortise lock body, not a complete trimmed lockset - what are my options versus the 8227-ET?
The Sargent 8227-ET ships as a complete lock with escutcheon trim in LE1, LS, LW1 or WT and a choice of eight lever designs. If you are replacing only the case behind existing trim, the BEST 45H Series heavy duty mortise lock body is a public entrance function unit with field reversible operation, and the 45HCA heavy duty mortise lockbody covers an intruder function. Baldwin's 6301LS is a lever-by-lever 2-1/2 inch backset entry/apartment mortise lock body.
23) Does the 8227 come with a lever on both sides, or is one side fixed?
Lever trim both sides. The 8227-ET uses lever handles, not knobs, which is what keeps it ADA compliant for a required accessible route. Inside lever always retracts the latch for egress; outside lever is locked and needs the key.
