Sargent 8235 LE1A 26D – Frequently Asked Questions

1) What does the storeroom function on the Sargent 8235 mortise lock actually do?
Storeroom function means the outside lever is always locked and only the key retracts the latch; the inside lever always retracts the latch for free egress. The 8235 adds a deadbolt that the single cylinder throws, so the opening can be dead-locked as well as latched. That is the usual choice for stock rooms, IT closets, mechanical rooms and any door that must never be left unlocked by accident.
2) Will the Sargent 8235-ET fit a 1-3/4 inch door, and what backset does it need?
It is built for 1-3/4 inch door thickness with a 2-3/4 inch backset, which is the standard commercial mortise prep. The latchbolt throws 3/4 inch, so it works with a standard ANSI mortise strike in the frame. If your door is thicker or thinner than 1-3/4 inches, this is not the configuration to order.
3) Do I have to order the Sargent 8235-ET handed, or is it field reversible?
Handing is field reversible on the 8200 Series lock body, so the same lock covers left and right hand openings without a special order. You still set the handing correctly during install before you mortise and hang it.
4) Can I put the Sargent 8235 storeroom lock on a fire-rated door?
Yes. The 8200 Series is UL 10C positive pressure certified and UL-cUL fire-rated up to 3 hours, and it's ANSI/BHMA Grade 1, which covers stair doors, corridor doors and other rated commercial openings.
5) What do I need to specify when ordering the Sargent 8235-ET besides the finish?
Four choices decide the part: cylinder (standard cylinder, less cylinder, 70 small format interchangeable core prep less core, or 60 large format interchangeable core prep less core), keying (keyed different, keyed alike, or a specific key code), escutcheon style (LE1, LS, LW1 or WT), and lever design (A, B, E, F, J, L, P or W). Finish runs 16 options from 26D satin chrome and 32D satin stainless through 10B oil rubbed bronze to BSP black and WSP white suede powder coat.
6) Can I key the Sargent 8235 into the master key system already in my building?
It works with all SARGENT key systems, including Degree, Signature, KESO and XC, so it can be brought into an existing Sargent masterkey hierarchy. If your system is another brand's, order it with the 70 small format or 60 large format interchangeable core prep less core and drop your own core in.
7) Will the Sargent 8235 mortise lock work in an aluminum storefront door?
No. It's a wide-stile commercial mortise lock on a 2-3/4 inch backset for 1-3/4 inch doors, which needs the stile depth of a hollow metal or solid core wood door. Narrow aluminum storefront stiles will not take that pocket. For glass and aluminum entries look at a narrow-stile deadlatch setup instead, such as the Kaba Ilco BR Series glass door bottom rail lock.
8) I need a storeroom mortise lock but the opening does not need a deadbolt - what should I use instead?
The Sargent 8235-ET is a single cylinder storeroom lock that includes a deadbolt in the lock body. If the opening only calls for the keyed latch, the Accentra 8805FL is a Grade 1 storeroom mortise lock, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an auxiliary-style body for 1-3/4 inch doors. Both cover the same storeroom access control without the deadbolt throw in the 8235 body.
9) What is the closest Grade 1 storeroom mortise lock equivalent to the Sargent 8235-ET from another manufacturer?
The Sargent 8235-ET is a Grade 1 storeroom function mortise lock in the 8200 Series with lever trim. The closest cross-brand equivalents on function and grade are the Accentra 8805FL, a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, and the Cal-Royal NM8080, a heavy duty Grade 1 storeroom mortise lockset rated for 1-3/4 inch doors with an interchangeable core option. All three give you a keyed outside lever that stays locked while the inside lever always retracts the latch.
10) We want keypad or credential access on a storeroom door instead of a key - what mortise locks do that?
The Sargent 8235-ET is a mechanical, non-electronic keyed lock. For credential or code access in a mortise prep, the Accentra NTM623-NR nexTouch Generation 3 uses a capacitive touchscreen keypad with cylinder override and no deadbolt, the BEST 45HZ EZ Series is an electronic keypad mortise lock with key override, and the Schlage LEMD-GRW is a Grade 1 ENGAGE wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating. The Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock if you want codes only with no reader.
11) Can I use an access control system to release a storeroom mortise lock instead of the Sargent 8235-ET?
The 8235-ET is a mechanical storeroom lock with no electrical operation. For an electrically controlled mortise lock in a storeroom opening, the Command Access ML190 is a heavy-duty storeroom function motorized mortise lock with field selectable fail safe or fail secure operation on 24VDC, the BEST 45HW is a heavy duty wired electromechanical mortise lock running 12V or 24V, and the Schlage L9092EU with 03A trim is a heavy duty electric lock or unlock outside lever mortise lock with request to exit on 12/24VDC for 1-3/4 inch doors.
12) Is a Baldwin 6310 storeroom mortise lock body interchangeable with the Sargent 8235-ET?
Not directly. The Sargent 8235-ET is built on a 2-3/4 inch backset commercial mortise body. The Baldwin 6310 entry/storeroom knob by knob mortise lock body and the 6310190RRLS lever by lever version use a 2-1/2 inch backset and fit doors 1-3/8 inch and over, so the door mortise pocket and cross-bore centers are different. Verify the existing prep backset before treating them as swaps.
13) What's the difference between ordering the 8235 with a standard cylinder versus less cylinder?
Standard cylinder ships the lock ready to key. Less cylinder ships the lock body and trim with no cylinder at all, which is what a locksmith wants when they are supplying and keying the cylinder themselves. The two interchangeable-core preps sit in between: the prep is there, the core is not, so you install your own SFIC or large format core on site.
14) Is the Sargent 8235-ET heavy duty enough for a high traffic door?
It's a Grade 1 heavy duty commercial mortise lock and Sargent completed UL's Cycle Above and Beyond test at 16 million cycles (Verification ID V584148). That's the tier you want on school corridors, hospital service doors and high-turnover retail stock rooms rather than a bored cylindrical lock.
15) What are the escutcheon trim options on the 8235 and does the trim change the door prep?
The ET designation means escutcheon trim, and four plate styles are offered: LE1, LS, LW1 and WT. All mount to the same 8200 Series mortise body with a 2-3/4 inch backset, so the pick is aesthetic and matching what's on your other openings rather than a change to the mortise pocket itself. If you want a rose instead of a full escutcheon plate, that's a different 8200 trim configuration.
16) Is the Sargent 8235-ET an electronic lock, and what should I order if I need access control?
No, the 8235-ET is a mechanical key-operated lock with no electronics. The 8200 Series does offer electromechanical versions that run 12 to 24VDC with EcoFlex technology, so staying in the same series keeps the prep consistent. If you want a standalone credential lock instead, the TownSteel FME-2000 Grade 1 RFID mortise lockset and the Dormakaba E-Plex 2066 electronic pushbutton mortise lock are both stocked alternatives.
17) I need a classroom or office function instead of storeroom on the same door prep. What are my options?
The 8200 Series covers 56 functions, so a classroom, office or privacy variant uses the same 2-3/4 inch backset mortise pocket and trim family, which keeps a building standardized. Across other brands we stock the Corbin Russwin ML2003 Grade 1 classroom mortise lockset for 1-3/4 inch doors, the Cal-Royal NM8070 Grade 1 classroom and NM8050 office/entrance locksets, and the Hager 3850E Grade 1 office mortise lock with escutcheon on a 2-3/4 inch backset.
18) What is the difference between the Sargent 8235-ET and the Corbin Russwin ML2003?
They are different lock functions. The Sargent 8235-ET is a storeroom function Grade 1 mortise lock with a single cylinder and deadbolt, so the outside lever is always locked and key operated. The Corbin Russwin ML2003 in the ML2000 Series is a Grade 1 mortise classroom lockset for 1-3/4 inch doors, where a key on the outside locks and unlocks the outside lever rather than keeping it permanently secured. Choose by which behavior the opening schedule calls for.
19) Is the BEST 45HCA public entrance lock body a substitute for the Sargent 8235-ET?
No, they are different functions. The Sargent 8235-ET is a storeroom function lock, meaning the outside lever stays locked at all times and requires a key. The BEST 45HCAC is a heavy duty mortise lock body in the 45H Series with a public entrance function, where the outside lever can be left unlocked for free access. If you need the door to remain secure at all times, the public entrance body is not an equivalent.
20) I have a mortise prep but the door does not need to be keyed - what replaces the Sargent 8235-ET?
The 8235-ET is a keyed lock. For a non-keyed mortise opening, the Schlage PM010 is a Grade 1 passage latch mortise lock for 1-3/4 inch doors, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating, and the Hager 3810E is a Grade 1 passage mortise lock with escutcheon trim, 2-3/4 inch backset, for doors 1-3/4 inch to 2-1/2 inch. For privacy instead of passage, the Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset.
21) Is an Emtek mortise entrance lockset an alternative to the Sargent 8235-ET on a commercial door?
No. The Sargent 8235-ET is a commercial Grade 1 heavy duty storeroom mortise lock. The Emtek 3102 Memphis, 3104 Hamilton and 3106 Manhattan mortise entrance locksets are dummy function, meaning they do not latch or lock at all and are used on inactive leaves. They will not secure a storeroom opening.
22) We want the storeroom lock and a separately keyed deadbolt - is the Sargent 8235-ET the right choice or should I use a separate deadbolt?
The Sargent 8235-ET carries the storeroom function and a single cylinder deadbolt in one mortise body, so one key operates both from the outside. If your facility wants the deadbolt controlled independently or electronically, the Kaba Ilco 185 Series is a no-handing mortise deadbolt, and 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 thick.
23) For a behavioral health or anti-ligature opening, what mortise lockset replaces a standard storeroom lever lock?
The Sargent 8235-ET uses a standard lever trim, which is not suitable 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 passage grade with satin stainless 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 in satin stainless steel.
24) Do the finishes on the Sargent 8235 match the chrome and stainless hardware already on my doors?
Sixteen finishes are offered, so matching an existing set is usually possible: 26 bright chrome over nickel and 26D satin chrome, 32 bright and 32D satin stainless steel, 03/04 bright and satin brass, 09/10 bright and satin bronze, 10B oil rubbed plus 10BE and 10BL dark oxidized satin bronze, 20D dark statuary bronze, 14/15 bright and satin nickel, and BSP black or WSP white suede powder coat.
