Sargent 8236 LE1A 20D – Frequently Asked Questions

1) What does the closet function on the Sargent 8236 actually do?
It is a closet lock function: keyed from the outside with a single cylinder, and the lever always retracts the latch from the inside so nobody can be locked in. Typical use is storage rooms, janitor closets and supply rooms where you want the door secured but free egress from inside. Handing is field reversible on the 8200 body, so one lock covers left or right hand openings.
2) What do I have to specify when ordering a Sargent 8236-ET mortise lock?
Four choices. Escutcheon style (LE1, LS, LW1 or WT), lever design (A, B, E, F, J, L, P or W), finish (16 options from 03 Bright Brass through 32D Satin Stainless and BSP/WSP suede powder coats), and the cylinder arrangement. On cylinder you pick a standard cylinder, less cylinder, 70 small format interchangeable core prep less core, or 60 large format interchangeable core prep less core, then a keying option: keyed different, keyed alike, or a specific key code. Choose None for keying if you order the lock less cylinder.
3) Can I order this Sargent lock to match the keys already in my building?
Yes, if your building is on a Sargent system. The 8200 Series works with all Sargent key systems including Degree, Signature, KESO and XC, and you can order keyed alike, keyed different, or to a specific key code you supply. If you run interchangeable cores, order the 70 prep for small format or the 60 prep for large format and supply your own cores.
4) Is the Sargent 8200 mortise lock fire rated for a labeled door?
Yes. The 8200 Series is UL 10C fire rated up to 3 hours and complies with NFPA 80, so it can go on a labeled opening. It is also ANSI/BHMA A156.13 Series 1000 Grade 1 and ADA compliant, which is what most institutional specs call for.
5) My door is 1-5/8 inch thick - can I still use the Sargent 8236-ET?
The Sargent 8236-ET is built for 1-3/4 inch door thickness with a 2-3/4 inch backset. If the leaf measures 1-5/8 inch, look at locks rated for that range: the Alarm Lock DL2700CR and DL3500CR are Grade 1 mortise locks listing 1-5/8 inch to 1-7/8 inch door thickness, both classroom function, and the DL4500 is a Grade 1 mortise deadbolt over the same thickness range. Note those are keypad electronic units rather than key-only locks.
6) What is a non-keyed alternative if the closet door does not need a cylinder?
For a closet or hall opening that only needs latching, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating, and the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors. The Hager 3810E is a Grade 1 passage mortise lock with escutcheon trim and a 2-3/4 inch backset if you want to keep the escutcheon look. The Sargent 8236-ET is a keyed single cylinder lock, so it is the choice only when the closet must be secured by key.
7) What is the closest Grade 1 mortise storeroom lock to the Sargent 8236-ET from another manufacturer?
The Accentra 8805FL is the nearest straight equivalent: a Grade 1 storeroom function mortise lock from the 8800 Series. The Cal-Royal NM8080 is another Grade 1 storeroom mortise lockset, rated for 1-3/4 inch doors and offered with an interchangeable core option. The Sargent 8236-ET is a Grade 1 heavy duty mortise lock with lever trim, keyed single cylinder, and escutcheon trim in LE1, LS, LW1 and WT styles. Keying systems differ between the three, so specify the cylinder and keyway that matches your existing system.
8) I need a classroom function mortise lock instead of a storeroom one - what should I order?
The Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset for 1-3/4 inch doors, and the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with an auxiliary deadlatch, also for 1-3/4 inch doors. The Sargent 8236-ET is built around a closet lock function with single cylinder keying, so if the opening needs the key to control the outside lever from either side in classroom fashion, one of those two is the correct part rather than the 8236.
9) What should I use instead of the Sargent 8236-ET on a behavioral health or ligature-resistant opening?
Use an anti-ligature trim design. 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, and the MRX-A-01 uses a ligature resistant arch trim, both passage function. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless. The Sargent 8236-ET uses conventional lever trim with escutcheon plates, which is not a ligature-resistant profile.
10) We need the mortise lock to be released electrically from the access control panel - what replaces the 8236-ET?
The Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit and 12/24VDC operation for 1-3/4 inch doors. The Command Access ML190 is a heavy duty motorized mortise lock with field selectable fail safe or fail secure operation on 24VDC and storeroom function. The BEST 45HW is a wired electromechanical mortise lock with 12V/24V operation. The Sargent 8236-ET is a purely mechanical lock with no electrical option, so an opening tied to access control needs one of those.
11) Escutcheon trim or sectional rose trim on a Sargent 8200 mortise lock, which should I use?
The 8236-ET is the escutcheon version, a full plate covering the lock area, which hides older or oversized trim holes and gives a heavier look for corridors and institutional work. Sectional rose trim is the lower-profile option and is usually chosen when narrow stiles or vision lites leave little room for a plate. Both trim styles share the same 8200 lock body prep, so the door mortise does not change between them.
12) How durable is the Sargent 8200 compared with other Grade 1 mortise locks?
All Grade 1 mortise locks meet the same ANSI minimum, but the 8200 was run through UL's Cycle Above and Beyond test to 16 million cycles (verification ID V584148), well past the grade requirement. That matters on high-traffic openings like school corridors and hospital service doors. Other heavy duty Grade 1 mortise options we carry include the Corbin Russwin ML2000 Series, the Cal-Royal NM8080 storeroom lock, and the BEST 45H Series lock body.
13) Is this Sargent 8200 lock an electronic or access control lock?
No. The 8236-ET is a mechanical key-and-lever mortise lock with no electronics. If you need credential or keypad access in a mortise prep, the BEST 45HZ EZ keypad mortise lock, the Schlage CO-100 standalone mortise lock, the Dormakaba E-Plex 2066 pushbutton mortise lock, or the TownSteel FME-2000 RFID mortise lockset are the electronic routes. For an electrified version of a mechanical mortise body, the Command Access ML190 gives field selectable fail safe or fail secure operation on 24VDC.
14) Do I need to order a left hand and right hand version of the Sargent 8236 separately?
No. Handing is field reversible on the 8200 lock body, so one part number covers both hands and you can stock a single lock for a mixed set of openings. That is useful for property managers standardizing across a building instead of carrying two SKUs.
15) Does the Sargent 8236-ET come with a cylinder and a strike, or do I order those separately?
It depends on the cylinder option you pick. Select Standard Cylinder and the lock ships with a Sargent cylinder and keys per the keying option chosen. Select Less Cylinder, or the 70 small format or 60 large format interchangeable core preps, and the lock arrives without a cylinder or core, which is what you want if you are pinning to your own system. The lock body, escutcheon trim and lever you select are part of the assembly.
16) Is an electronic mortise lock a substitute for the Sargent 8236-ET?
Only if you want credential access rather than mechanical key control. The Sargent 8236-ET is a non-electronic mortise lock operated by lever and single cylinder key. Electronic mortise options include the Schlage CO-100 standalone keypad mortise lock, Grade 1 heavy duty for 1-3/4 inch doors, the TownSteel FME-2000 Grade 1 RFID mortise lockset, and the Dormakaba E-Plex E5086 Grade 1 pushbutton and card mortise lock. Those require battery or wiring and programming; the 8236-ET does not.
17) What looks like a mortise lockset but will not work as a replacement for the 8236-ET?
Dummy and trim-only items. The Schlage L0170 is half dummy trim with no latch, and the Emtek 3102 Memphis and 3104 Hamilton mortise entrance locksets are dummy function. The Falcon MESC600DT is dummy escutcheon lever trim for M9900 Series exit devices, not a lock body at all. The Sargent 8236-ET is a complete keyed mortise lock with a lock body, cylinder and escutcheon lever trim, so none of those dummy items will secure or latch the opening.
18) I need just the mortise lock body, not a complete lockset with trim - what are my options?
The BEST 45H Series 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. Baldwin also offers body-only units such as the 6310 entry/storeroom mortise lock body with a 2-1/2 inch backset for doors 1-3/8 inch and over. The Sargent 8236-ET ships as a complete assembly with escutcheon lever trim in eight lever designs, so choose a body-only part if the existing trim is being reused.
19) What is the difference between the Sargent 8236-ET and the Hager 3850E for an office door?
The Hager 3850E is a Grade 1 office function mortise lock with lever and escutcheon trim, non-keyed, on a 2-3/4 inch backset for doors 1-3/4 inch to 2-1/2 inch. The Sargent 8236-ET shares the 2-3/4 inch backset and escutcheon lever trim but is a keyed single cylinder closet function lock for 1-3/4 inch doors. The deciding factor is whether the opening needs cylinder key control or non-keyed office operation.
20) Is there a privacy function mortise lock for restrooms instead of the closet function 8236-ET?
Yes. 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 doors 1-3/4 inch to 2 inch. The Sargent 8236-ET is a closet function keyed lock with no inside privacy turn, so it is not the right part for a bath or restroom opening.
