Sargent 8236 EA 32 – Frequently Asked Questions

1) Will the Sargent 8236 mortise lock fit a standard 1-3/4 inch commercial door?
Yes. The Sargent 8236 is built for 1-3/4 inch door thickness with a 2-3/4 inch backset, which is the standard commercial mortise prep. If your door is prepped to a different backset or is thicker than 1-3/4 inches, this is not the right lock body.
2) What does the closet function on the Sargent 8236 actually do day to day?
The 8236 is a single cylinder closet-function mortise lock: the key on the outside controls the latch, and the inside lever always retracts it for free egress. It suits storage and supply rooms where you want the door secured from the corridor side but never lockable against someone inside.
3) Do I have to order the Sargent 8236 handed for left or right doors?
No. The 8200 Series lock body is field reversible for handing, so one lock covers left and right hand openings and you set it during install. That also makes it easier to stock a single part across a building.
4) Can I use a Sargent mortise lock on a fire rated door?
Yes. The 8200 Series is UL 10C positive pressure certified with a 3-hour fire rating, so it can go on rated openings up to that level. Install it with the fire rated strike and frame prep called for on the opening.
5) What do I need to specify when ordering the Sargent 8236 besides finish?
Four things decide the part: cylinder (standard cylinder, less cylinder, 70 small format interchangeable core prep less core, or 60 large format IC prep less core), keying (keyed different, keyed alike, or a specific key code, or none if you chose less cylinder), lever style (A, B, E, F, J, L, P or W), and rose (E at 3-1/16 inch, L at 3-1/2 inch, LN at 2 inch, or O at 2-3/4 inch). Finish runs 16 options from 03 bright brass through 26D satin chrome, 32D satin stainless and BSP/WSP powder coats.
6) Will the Sargent 8236 work with the masterkey system already in my building?
If your facility is on a Sargent system, yes. The 8200 Series integrates with all SARGENT key systems including Degree, Signature, KESO and XC. If you key your own cores, order it with the 70 small format IC prep or 60 large format IC prep less core and drop in your existing core.
7) What is the closest cross-brand equivalent to the Sargent 8236 mortise lock for a storeroom opening?
The Sargent 8236 is a Grade 1 mortise lock with a storeroom function and a single-cylinder keyed design. The closest cross-brand matches are the Accentra 8805FL, a Grade 1 storeroom mortise lock from the 8800 Series with an Arcadia lever, and the Cal-Royal NM8080, a Grade 1 heavy duty storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. Both carry the same Grade 1 rating and storeroom function as the 8236.
8) I need a classroom function instead of storeroom - what mortise lock should I use?
The Sargent 8236 is built for a storeroom opening, so for a classroom opening choose a lock catalogued with that function: the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series for 1-3/4 inch doors, and the Cal-Royal NM8070 is a Grade 1 heavy duty classroom mortise lockset with an auxiliary deadlatch, also for 1-3/4 inch doors.
9) Can I use a Baldwin 6310 mortise lock in place of the Sargent 8236?
They are not interchangeable in the same prep. The Sargent 8236 uses a 2-3/4 inch backset on a 1-3/4 inch door, while the Baldwin 6310 entry/storeroom mortise lock body is a 2-1/2 inch backset unit for doors 1-3/8 inch and over. If the door is already mortised for a 2-3/4 inch backset, the Baldwin body will not line up.
10) Is this Sargent 8236 an electronic lock, and what is EcoFlex?
As configured here it is a mechanical lock, not an electrified one. EcoFlex is the 8200 Series technology used on the electromechanical functions in the family, which run on 12 to 24VDC with up to 89 percent energy savings. If you need an access-control-driven mortise lock, that is a different function code in the series, not the 8236.
11) Is a Grade 1 mortise lock overkill for a storage room, or should I use a cylindrical lock?
For high traffic commercial openings the mortise body earns its keep: the 8200 carries ANSI/BHMA A156.13 Series 1000 Grade 1 and UL cycle testing at 16 million cycles. A lighter door in low traffic can be handled by a Grade 1 cylindrical such as the Schlage PC10, but that is a passage lock, not a keyed closet lock, so it will not secure the room.
12) I need the same look across all my doors but some openings are passage only. What pairs with the Sargent 8236?
Stay in the 8200 Series for matching trim: the family runs 56 functions covering mechanical, electromechanical, security and monitoring, all sharing the same lever and rose trim. Choose the passage or privacy function for the non-keyed openings and order the same lever letter, rose and finish so the corridor reads consistently.
13) Which rose size should I pick for the Sargent 8236 on a narrow stile or glass-lite door?
Four roses are offered: LN at 2 inches, O at 2-3/4 inches, E at 3-1/16 inches and L at 3-1/2 inches. The LN and O roses cover tighter stiles and doors with a lite close to the lock edge; the E and L roses give more coverage over an older prep or worn door face.
14) Can I order the Sargent 8236 without a cylinder and use my own?
Yes. Pick the less cylinder option and select None for keying, and the lock ships without a cylinder. If you run interchangeable cores, take the 70 small format IC prep or 60 large format IC prep instead so the body is machined for your core.
15) If the door does not need to be keyed, what is a simpler alternative to the Sargent 8236?
The Sargent 8236 is a keyed single-cylinder mortise lock, so on an opening that only needs latching, a non-keyed mortise lock is simpler. The Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, 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 3810S is a Grade 1 passage mortise lock with a rose and 2-3/4 inch backset for 1-3/4 to 2-1/2 inch doors.
16) What should I use instead of the Sargent 8236 if I need keypad or credential access rather than a key?
The Sargent 8236 is a mechanical keyed mortise lock. For credential-based access on a mortise prep, the Alarm Lock DL3500CR is a Grade 1 electronic mortise lock with 300 user codes and a classroom function for 1-5/8 to 1-7/8 inch doors, the TownSteel FME-2000 is a Grade 1 heavy duty mortise lockset with RFID technology for 1-3/4 inch doors, and the Schlage CO-100 is a Grade 1 heavy duty standalone electronic mortise lock with a keypad reader in the privacy function.
17) Is the Schlage L0170 an alternative to the Sargent 8236?
No. The Sargent 8236 is a keyed Grade 1 mortise lock with a working latch, while the Schlage L0170 is a Grade 1 heavy duty half dummy trim in the L Series with a dummy function - it mounts as a pull with no latch or cylinder. The Emtek 3102 Memphis and 3104 Hamilton mortise entrance locksets are likewise catalogued as dummy function. Use those only on inactive leaves, not where the 8236 would go.
18) What is an alternative to the Sargent 8236 for a restroom or bedroom door that needs privacy?
The Sargent 8236 is keyed with a storeroom function, which is not a privacy arrangement. For privacy openings, the Cal-Royal NM8440 is a Grade 1 heavy duty privacy mortise lockset with a deadbolt for 1-3/4 inch doors, and the Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for 1-3/4 to 2 inch doors.
19) We need electrified access control on this opening - how does the Sargent 8236 compare to a powered mortise lock?
The Sargent 8236 body is offered with EcoFlex electromechanical functions operating on 12 to 24VDC. Peers built around the same voltage range include the BEST 45HW wired electromechanical mortise lock, a heavy duty 12V/24V unit, the Command Access ML190 motorized mortise lock with field selectable EL/EU operation on 24VDC in a heavy-duty storeroom function, and the Schlage L9092EU with an electrically controlled outside lever, keyed outside, request-to-exit, at 12/24VDC on 1-3/4 inch doors.
20) Is there a behavioral health or anti-ligature alternative to the Sargent 8236?
The Sargent 8236 uses standard lever trim on a rose. For openings that call for ligature-resistant trim, the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel with a passage function, the MRX-A-01 is the same passage function with satin stainless 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.
21) What is the difference between the Sargent 8236 and a cylindrical lock like the Schlage PC10?
The Sargent 8236 is a mortise lock, meaning it drops into a rectangular pocket machined into the door edge and carries a keyed single-cylinder storeroom function. The Schlage PC10 is a Grade 1 cylindrical passage lock with a rose, non-keyed, for 1-3/4 inch doors - it installs through bored holes rather than a mortise pocket and provides no keying. The two preps are not interchangeable without new door machining.
22) Which alternatives to the Sargent 8236 are rated Grade 2 rather than Grade 1?
The Sargent 8236 is rated Grade 1. Among mortise peers, the Schlage LEBMB-ADD mobile-enabled mortise lock with push button and LED is a Grade 2 unit with a 3-hour fire rating for 1-3/4 inch doors, and the Dormakaba Saffire LX-I-M002 electronic RFID mortise lockset is BHMA Grade 2. If the specification calls for Grade 1, those two do not meet it.
23) Does the Sargent 8236 meet ADA requirements for lever operation?
Yes, the 8200 Series is ADA compliant and all trim on the 8236 is lever style, which satisfies the operable-without-tight-grasping requirement for accessible openings.
24) If I only need the lock body and will reuse existing trim, what are my options next to the Sargent 8236?
The Sargent 8236 is supplied as a complete lock with lever and rose trim, choosable across A, B, E, F, J, L, P and W levers. If you are replacing only the chassis, the BEST 45H heavy duty mortise lock body in a public entrance function with field reversible operation and the BEST 45HCA heavy duty mortise lockbody with an intruder function are catalogued as lock bodies rather than complete trimmed sets.
25) We want a mortise deadbolt only, not a latching lockset - what replaces the Sargent 8236?
The Sargent 8236 is a latching lever lockset. If the opening needs a deadbolt alone, the Kaba Ilco 185 Series mortise lock is catalogued with a deadbolt function and no handing, and the Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad for 1-5/8 to 1-7/8 inch doors.
