Sargent 8256 TR H001 26D – Frequently Asked Questions

1) Will the Sargent 8200 Series mortise lock fit my 1-3/4 inch door, and what backset does it need?
The 8256 mortise lock is built for 1-3/4 inch door thickness with a 2-3/4 inch backset, which is the standard commercial mortise pocket. If your existing pocket was cut for a 2-3/4 inch backset mortise body, this drops into the same prep. Doors thinner or thicker than 1-3/4 inches are outside what this configuration covers.
2) Do I have to specify handing when I order this Sargent mortise lock?
No. The 8256 is field reversible, so one lock covers left or right hand openings and you reverse the handing on site. Useful if you are stocking spares for a building with doors swinging both ways.
3) Will the Sargent 8256 latch into my existing ANSI strike?
The lock has a 3/4 inch latchbolt throw and ships with a curved lip strike. A 3/4 inch throw is standard for a commercial mortise latch, so an existing ANSI strike prep in the frame will normally accept it. Check that the frame lip cutout matches the curved lip profile if you are keeping the old strike.
4) What do I have to choose for the cylinder and keying when ordering the Sargent 8256?
Cylinder and keying are both required selections. For the cylinder you pick a standard cylinder, less cylinder, a 70 small format interchangeable core prep less core, or a 60 large format interchangeable core prep less core. Keying is keyed different, keyed alike, or to a specific key code you enter; select the None keying option if you chose less cylinder. Locksmiths who key their own cores usually take one of the IC preps less core.
5) Can I key this Sargent office lock into the master key system already in my building?
It works with all SARGENT key systems, including Degree, Signature, KESO and XC, and the standard cylinder is an LA keyway. If your existing building is on a Sargent LA system, this can be keyed alike or keyed into the master. If you run a different manufacturer's keyway, order it with an interchangeable core prep less core and drop in your own core.
6) Is the Sargent 8200 Series mortise lock fire rated and ADA compliant?
Yes on both. The 8200 Series is UL 10C fire rated up to 3 hours and ADA compliant, and it meets ANSI/BHMA A156.13 Series 1000 Operational Grade 1. The lever trim is what satisfies the ADA operable-hardware requirement. It also completed UL's Above and Beyond cycle test at 16 million cycles under Verification ID V584148.
7) What is the closest equivalent to the Sargent 8256 office entry mortise lock from another manufacturer?
The Sargent 8256 is a Grade 1 keyed mortise lock in the office/inner entry function. The closest same-function peer is the Cal-Royal NM8050, a heavy duty Grade 1 entrance/office mortise lockset with auxiliary deadlatch for 1-3/4 inch doors. The Hager 3850E is also an office-function Grade 1 mortise lock with lever and escutcheon on a 2-3/4 inch backset, but it is non-keyed, so it does not replace the 8256 where key control at the outside lever is required.
8) Does the Sargent 8256 work for access control tie-in, or do I need an electrified mortise lock?
The 8256 is a mechanical office/inner entry lock with no electrical option in its configuration. For an opening on an access control system, the Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock with request to exit and 12/24VDC operation for 1-3/4 inch doors, the BEST 45HW is a heavy duty wired electromechanical mortise lock with 12V/24V operation, and the Command Access ML190 is a heavy-duty motorized mortise lock with field selectable EL/EU operation on 24VDC in the storeroom function.
9) The opening needs to stay locked from outside at all times - is the Sargent 8256 the right function or should I use a storeroom lock?
The 8256 is an office/inner entry function, which allows the outside lever to be left unlocked. For an opening that must stay secured at all times, a storeroom function is the correct choice: the Accentra 8805FL is a Grade 1 storeroom mortise lock with Arcadia lever, and the Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors.
10) Will a Sargent 8256 fit a 2-1/2 inch backset mortise prep?
The Sargent 8256 uses a 2-3/4 inch backset. If the existing prep is a 2-1/2 inch backset, look at the Baldwin 6301LS entry/apartment lever by lever mortise lock body on a 2-1/2 inch backset for doors 1-3/4 inch and over, or the Baldwin 6310190RRLS entrance/storeroom lever by lever mortise lock, also 2-1/2 inch backset, for doors 1-3/8 inch and over in right hand reverse.
11) What lever and rose choices come with the Studio Collection trim on this Sargent lock?
Seven Studio Collection lever designs are offered: H001, H002, H003, H004, H005 and H006, plus H011. Rose trim comes in four sizes, the E2 at 2-11/16 inches, E3 at 2-1/16 inches, E4 at 3-1/4 inches, and the TR at 2-3/16 inches. If you are replacing one lock on a floor of existing Sargent openings, match the lever letter and rose size to keep the look consistent.
12) What finishes can I get the Sargent 8256 in to match the rest of my building?
Sixteen finishes are available: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B oil rubbed dark oxidized satin bronze, 10BE, 10BL, 14 bright nickel, 15 satin nickel, 20D dark statuary bronze, 26 bright chrome, 26D satin chrome, 32 bright stainless, 32D satin stainless, BSP black suede powder coat and WSP white suede powder coat. 26D and 32D are the usual choices on commercial openings.
13) Is a mortise lock like the Sargent 8200 overkill for a low traffic interior office door?
It depends on the traffic and the door prep. The 8200 is a heavy duty commercial mortise body, tested to 16 million cycles, and it needs a mortise pocket routed into the door edge. If the door already has a cylindrical bore and the traffic is light, a bored lock is the cheaper and faster install, for example the Schlage PC10 Grade 1 passage cylindrical lock for non-keyed openings. Where you need key control and long service life on a heavily used entry, the mortise body is the right call.
14) What is a simpler non-keyed alternative if the door does not need a cylinder?
The Sargent 8256 is a keyed single cylinder lock. Where no key control is needed, 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 the Hager 3810S is a Grade 1 passage mortise lock with rose on a 2-3/4 inch backset. For a bathroom or bedroom, the Hager 3840S is a Grade 1 privacy mortise lock on the same 2-3/4 inch backset.
15) Can I get the same office function with keypad or credential access instead of a key?
The Sargent 8256 is a mechanical, non-electronic lock keyed to the LA keyway. If the opening needs code or credential access, the Schlage LEBMB-ADD is a mobile-enabled mortise lock covering privacy, office and apartment functions with push button and LED, rated Grade 2 with a 3 hour fire rating. Other electronic mortise options include the Accentra NTM623-NR nexTouch with capacitive touchscreen keypad and cylinder override, and the Dormakaba E-Plex 2066 electronic pushbutton keyless mortise lock.
16) For a behavioral health or detention-type room, is the Sargent 8256 with Studio levers appropriate?
The 8256 uses Studio Collection levers, which are standard commercial lever trim and not ligature resistant. For those rooms, 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 function 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.
17) Is the Schlage L0170 an alternative to the Sargent 8256 for an inactive leaf?
No - they do different jobs. The Sargent 8256 is a keyed, latching office entry mortise lock. The Schlage L0170 is a Grade 1 heavy duty half dummy trim, non-keyed dummy function for 1-3/4 inch doors, so it has no latch and no cylinder. Use it only on an inactive leaf or pull-only opening where the lever needs to match, not as a substitute for a working 8256.
18) Can I use a cylindrical lock like the Schlage PC10 in place of the Sargent 8256?
Only if you are changing the door prep. The Sargent 8256 is a mortise lock, which needs a mortise pocket routed into the door edge. The Schlage PC10 is a Grade 1 cylindrical lock with rose in passage function for 1-3/4 inch doors and is bored through the face of the door. The two preps are not interchangeable, and the PC10 is also non-keyed, so it does not carry the 8256's single cylinder office entry function.
19) Is there an installation template for the Sargent 7800/8200 mortise lock prep?
Yes. Sargent publishes a 7800 and 8200 Series mortise lock installation template covering all sectional rose trims and escutcheon trims, plus a separate installation guide for mortise locks with Studio Collection levers. Use the template to mark the pocket, cross bores and trim holes before you route.
20) What should I use if the door only needs a deadbolt and no lever?
The Sargent 8256 combines a keyed cylinder with lever trim and a latchbolt. If the opening only calls for a bolt, the Kaba Ilco 185 Series is a deadbolt-function mortise lock with no handing, and the Alarm Lock DL4500DB 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.
