Sargent 8235 EA 26D – Frequently Asked Questions

1) Will the Sargent 8235 mortise lock fit a 1-3/4 inch door with a 2-3/4 inch backset prep?
That's exactly the prep it's built for. The Sargent 8235 mortise lock body uses a 2-3/4 inch backset and is listed for 1-3/4 inch door thickness. If your existing mortise pocket was cut for a standard commercial 2-3/4 inch backset lock, the 8235 drops into it. Thinner doors, or doors over 1-3/4 inches, need a different lock.
2) What does storeroom function mean on the Sargent 8235, and is it right for a stockroom or mechanical room?
Storeroom function means the outside lever is always locked. Entry is by key only, and the inside lever always retracts the latch for free egress. There is no way to leave the outside lever unlocked, which is what you want on a stockroom, mechanical room, or IT closet. The 8235 also carries a single cylinder deadbolt, so the same key throws the bolt for added security when the room is left unattended.
3) Can the Sargent 8235 go on a fire-rated door?
Yes. The 8235 mortise lock is UL 10C positive pressure fire rated up to 3 hours and compliant with NFPA 80, so it is usable on rated openings in corridors, stairwells and exit access. Note the deadbolt: on a rated opening the inside lever must retract both latch and bolt in one motion for code-compliant egress, so verify the opening's hardware set with your AHJ.
4) Will the 3/4 inch latchbolt throw on the Sargent 8235 catch my existing ANSI strike?
The 8235 has a 3/4 inch latchbolt throw with a curved lip strike supplied. Three-quarters of an inch is the normal commercial mortise latch throw, so it engages a standard ANSI 4-7/8 inch mortise strike. Where the frame has a heavy gap or the door has settled, check the strike lip projection rather than the throw itself.
5) Do I have to specify handing when I order the Sargent 8235?
No. The 8235 lock body is field reversible, so one lock covers left or right hand doors with no extra parts and no separate handed SKU. You reverse it on the bench before install. Lever, rose, and finish are the choices that actually matter on the order.
6) What do I have to pick for the cylinder and keying on the Sargent 8235, and can I use my own cores?
Four cylinder choices: standard cylinder, less cylinder, 70 prep for small format interchangeable core (less core), or 60 prep for large format interchangeable core (less core). If you already key your building on SFIC or an LFIC core such as a Sargent Signature or Degree core, order the matching prep and drop your own core in. Keying options are keyed different, keyed alike, or to a specific key code you supply. Pick None for keying when you order less cylinder. The lock works with all Sargent key systems including Degree, Signature, KESO and XC.
7) Is the Sargent 8235 an electrified lock, or do I need something else for access control?
The 8235 as configured is a mechanical, key-operated mortise lock, not an electrified one. If the opening needs to be released or monitored from a card reader or access control panel, look at an electromechanical mortise lock instead: the BEST 45HW wired mortise lock runs 12V/24V, and the Command Access ML190 Series is a motorized storeroom-function mortise lock with field selectable EL/EU operation on 24VDC.
8) What is a direct cross for the Sargent 8235 storeroom mortise lock from another manufacturer?
The Sargent 8235 is a Grade 1 storeroom function mortise lock. The closest like-for-like crosses are the Accentra 8805FL, a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, and the Cal-Royal NM8080, a Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors. Where the 8235 differs is its single cylinder deadbolt in addition to the storeroom latch, so if the opening needs the deadbolt throw, confirm that on the cross before you swap.
9) Which lever and rose options does the Sargent 8235 come with, and how do I match the other doors in my building?
Eight lever designs (A, B, E, F, J, L, P, W) and four rose styles: LN rose at 2 inches (51mm), O rose at 2-3/4 inches (67mm), E rose at 3-1/16 inches (78mm), and L rose at 3-1/2 inches (89mm). If you are adding to an existing 8200 Series set, match the lever letter and rose letter off one of the installed locks and order the same combination in the same finish, and the new opening will look identical.
10) How durable is the Sargent 8235 for a high traffic entrance?
It is a Grade 1 heavy duty lock certified to ANSI/BHMA A156.13 Series 1000 operational Grade 1, and Sargent completed a UL Cycle Above and Beyond test at 16 million cycles (verification ID V584148). That puts it in the range you want for main entrances, school corridors and healthcare traffic rather than a light-duty interior opening.
11) I need a classroom or privacy function instead of storeroom on the same kind of door. What should I order?
Storeroom is key-only from the outside with no lever unlocking, so it is wrong for a classroom or restroom. For classroom function in a Grade 1 mortise on a 1-3/4 inch door, the Corbin Russwin ML2003 (ML2000 Series) or the Cal-Royal NM8070 both cover it. For privacy on a bed or bath, the Cal-Royal NM8440 is a Grade 1 privacy mortise lock with deadbolt, and the Hager 3840S is a Grade 1 privacy mortise with a 2-3/4 inch backset for 1-3/4 to 2 inch doors.
12) My door is thicker than 1-3/4 inches. Is there a mortise lock that covers it?
The Sargent 8235 is listed at 1-3/4 inch door thickness, so an unusually thick door is outside it. The Hager 3810S and 3810E (3800 Series, 2-3/4 inch backset) are listed for 1-3/4 to 2-1/2 inch doors, and the Hager 3850E office function covers the same 1-3/4 to 2-1/2 inch range. Those are passage and office functions rather than storeroom, so confirm the function matches the opening.
13) What if the door does not need to be keyed at all?
The Sargent 8235 is a keyed storeroom lock, so on a non-keyed opening use a passage or privacy mortise lock instead. The Schlage PM010 is a Grade 1 non-keyed 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 for bed or bath the Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset.
14) Is the Schlage L0170 an alternative to the Sargent 8235?
No. The Schlage L0170 is Grade 1 half dummy trim, a non-keyed lever that does not latch or lock at all. The Sargent 8235 is a keyed storeroom mortise lock with a single cylinder deadbolt. Use the L0170 only on an inactive leaf; it will not secure an opening.
15) What do I use on a residential-style entrance door instead of the Sargent 8235?
The Sargent 8235 is a commercial heavy duty Grade 1 mortise lock. For an entrance or apartment application on a lighter door, the Baldwin 6301LS is a lever by lever entrance/apartment mortise lock body with a 2-1/2 inch backset for doors 1-3/4 inch and over, and the Baldwin 6310 is an entrance/storeroom knob by knob mortise body with a 2-1/2 inch backset for doors 1-3/8 inch and over. Note the 2-1/2 inch backset against the 2-3/4 inch prep the 8235 uses.
16) For a behavioral health or ligature-resistant opening, what replaces the Sargent 8235?
The 8235 uses standard lever and rose trim. 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, the MRX-A-01 is the arch trim version, and the Marks USA 5PDN is a Grade 1 hospital passage push/pull paddleset that is ligature resistant and ADA compliant. All three are passage function, so they do not carry the 8235 storeroom keying.
17) Which mortise lock should I spec if I need classroom lockdown from inside the room rather than storeroom function?
The Sargent 8235 storeroom function locks the outside lever at all times and is not an intruder lock. For lockdown from within the classroom, the BEST 45HCA heavy duty mortise lockbody carries an intruder function, the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset with ANSI strike and steel escutcheon for 1-3/4 inch doors, and the TownSteel FME-4000 is a Grade 1 heavy duty electronic intruder classroom mortise lockset with RFID.
18) I need the outside lever to release electrically on access control - what mortise lock does that?
The Sargent 8235 is a mechanical lock with no electrified lever control. For an electrified outside lever, the Schlage L9092EU with 03A trim is a heavy duty mortise lock with electric lock/unlock outside lever, keyed outside, request to exit, on 12/24VDC for 1-3/4 inch doors, and the BEST 45HW is a heavy duty wired electromechanical mortise lock with 12V/24V operation.
19) Is a mortise deadbolt like the Alarm Lock DL4500 the same as the deadbolt on the Sargent 8235?
No. The DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes and privacy keypad for doors 1-5/8 to 1-7/8 inch - deadbolt only, no latch or lever. The Sargent 8235 is a storeroom lockset with lever trim plus a single cylinder deadbolt in one mortise body, so it handles both latching and deadbolting from a single prep.
20) What is the difference between the Sargent 8235 and an office or entrance function mortise lock?
The Sargent 8235 is storeroom function: the outside lever stays locked and a key retracts the latch, so the door is never left unlocked by trim. The Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with auxiliary deadlatch for 1-3/4 inch doors, and the Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon, non-keyed, on a 2-3/4 inch backset. Office function allows the outside lever to be left unlocked for business hours.
21) What finishes is the Sargent 8235 available in for a stainless or oil rubbed bronze building standard?
Sixteen finishes: bright and satin brass (03, 04), bright and satin bronze (09, 10), dark oxidized satin bronze in three variants (10B oil rubbed, 10BE, 10BL clear coated), bright and satin nickel (14, 15), dark statuary bronze (20D), bright and satin chrome (26, 26D), bright and satin stainless steel (32, 32D), plus black and white suede powder coat (BSP, WSP). For a stainless standard, 32D satin stainless is the usual commercial pick; for oil rubbed bronze, 10B.
22) Can I use a Dormakaba E-Plex 5086 in place of the Sargent 8235 on a fire door?
They are different animals. The Sargent 8235 is a mechanical Grade 1 storeroom mortise lock, UL 10C positive pressure fire rated up to 3 hours. The Dormakaba E-Plex E5086 is a Grade 1 back to back electronic pushbutton and card entry/egress mortise lock, which brings credential management and requires programming rather than a key system. Verify the fire listing on the electronic unit against your opening before substituting.
