Sargent 8266 EA 26D – Frequently Asked Questions

1) Will the Sargent 8266 privacy mortise lock fit a standard 1-3/4 inch commercial door?
Yes. The 8266 is built for a 1-3/4 inch door with a 2-3/4 inch backset, which is the standard commercial mortise prep. If your doors are thicker or you are working an older 1-3/8 inch interior door, this is not the right body for the opening.
2) Does the Sargent 8266 need to be ordered left hand or right hand?
No handing to specify. The 8266 lock body is field reversible, so the same lock is configured on site for a left or right hand door with no extra parts. That is what lets a property manager stock one lock for a building with mixed swings.
3) What does the 8266 privacy function actually do on a restroom or bedroom door?
Privacy bath/bedroom function: the deadbolt is thrown from the inside for occupancy, and there is no key cylinder in the function itself. It is a non-keyed lock, so nobody is carrying a key for this door. Use it on single-occupancy restrooms, patient rooms, dorm and apartment bedrooms. If you need a key to get in from the corridor, this is the wrong function.
4) Is the Sargent 8266 approved for a fire rated door?
Yes. The 8266 is UL 10C fire rated up to 3 hours and complies with NFPA 80, so it can go on a rated opening in a stairwell, corridor, or cross-corridor assembly. It also carries ANSI/BHMA A156.13 Series 1000 Operational Grade 1.
5) What do I have to specify when ordering a Sargent 8266 mortise lock?
Four things decide the part: lever design, rose, finish, and (only if you are adding one) the cylinder and keying option. Levers run A, B, E, F, J, L, P and W. Roses are E at 3-1/16 inches, L at 3-1/2 inches, LN at 2 inches, and O at 2-3/4 inches. Sixteen finishes are offered, from 26D satin chrome and 32D satin stainless through 10B oil rubbed bronze and BSP black suede powder coat. Since 8266 is a non-keyed privacy function, most orders take no cylinder at all.
6) What looks like a substitute for a Sargent 8266 privacy mortise lock but is not?
Two things get ordered by mistake. A dummy trim such as the Schlage L0170 half dummy is a Grade 1 mortise non-keyed lever for 1-3/4 inch doors, but it is trim only with no latch and no privacy mechanism - it will not hold a bathroom door shut. And an electronic mortise deadbolt like the Alarm Lock DL4500, a Grade 1 deadbolt function with a privacy keypad for 1-5/8 to 1-7/8 inch doors, uses the word privacy but is a keypad deadbolt, not a lever-operated privacy latch. The Sargent 8266 is a mechanical privacy bath/bedroom mortise lock with lever handles.
7) Can a Sargent 8266 be used on a classroom or storeroom door?
No - the 8266 is a non-keyed privacy bath/bedroom function, so it has no outside cylinder to secure the door. For a classroom opening, the Cal-Royal NM8070 is a heavy duty Grade 1 classroom mortise lockset with auxiliary deadlatch for 1-3/4 inch doors, and the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for the same door thickness. For a storeroom, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option, and the Accentra 8805FL is a Grade 1 storeroom mortise lock with an Arcadia lever.
8) What is the closest cross-brand equivalent to a Sargent 8266 privacy mortise lock?
The Cal-Royal NM8440 is the nearest match from another manufacturer: a heavy duty Grade 1 privacy mortise lockset with deadbolt, rated for 1-3/4 inch doors. The Sargent 8266 is also a Grade 1 privacy bath/bedroom mortise lock, non-keyed, with rose trim and lever handles. Hager's 3840S is a second Grade 1 privacy mortise lock with a 2-3/4 inch backset, listed for 1-3/4 inch to 2 inch doors. If the drawing calls for a privacy mortise function and the specifier allows an equal, those are the two to put in front of them.
9) The door only needs to latch, not lock. What mortise lock replaces a privacy lock on a hall or closet door?
Use a passage function instead. The Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, for 1-3/4 inch doors, and the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating. Hager's 3810S is a Grade 1 passage mortise lock with rose trim and a 2-3/4 inch backset. None of those carry the thumbturn and interior locking of the Sargent 8266 privacy function, so a bathroom or bedroom opening still needs the 8266.
10) We need privacy on the door but with keypad access for staff. What replaces a Sargent 8266 there?
The Schlage CO-100 standalone electronic mortise lock is offered in a privacy function with a keypad reader, Grade 1 heavy duty, for 1-3/4 inch doors. That covers privacy plus code-based entry in one mortise body. The Sargent 8266 is a mechanical, non-electronic lock, so it has no credential side at all - it locks from inside only. Choose the CO-100 when the facility wants an audit or code list, and the 8266 when the opening is purely mechanical.
11) We need a ligature resistant lock in a behavioral health room. Does the Sargent 8266 work?
The 8266 is a standard lever privacy mortise lock and is not built as an anti-ligature product. For that setting, the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel, the MRX-A-01 is the ligature resistant arch trim version, 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. All three are passage function, so pair them with the facility's privacy strategy rather than expecting the 8266's interior locking.
12) Will a Sargent 8266 hold up on a high traffic restroom door in a school or hospital?
It is a Grade 1 heavy duty commercial mortise lock, and Sargent's UL Cycle Above and Beyond test on it was completed at 16 million cycles. That cycle count is the reason it gets specified for school restrooms, patient rooms, and other openings that see constant use, where a Grade 2 residential-weight lock wears out.
13) Which rose size should I pick for a Sargent 8266, and does it matter on a narrow door?
Rose diameter is what decides whether the trim lands cleanly on the stile. The LN rose is the small one at 2 inches, O is 2-3/4 inches, E is 3-1/16 inches, and L is the largest at 3-1/2 inches. On a narrow stile or where you are covering old fastener holes from a previous lock, the diameter is your deciding number. All four are rose trim, not escutcheon, so the lever mounts on a round plate rather than a full plate.
14) Can I match Sargent 8266 privacy locks to the keyed locks already in my building?
The 8266 itself is a privacy function with no key, so there is nothing to key on the restroom and bedroom doors. Where it matters is trim consistency: order the same lever design, rose, and finish you used on your keyed 8200 Series openings and the whole building reads as one set. On the keyed doors, the 8200 lock body integrates with all Sargent key systems, including Degree, Signature, KESO and XC.
15) What are the alternatives to the Sargent 8266 if I need a Grade 1 privacy mortise lock from another brand?
Two direct peers. The Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for a 1-3/4 inch door. The Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset that covers a 1-3/4 to 2 inch door range, which is the one to look at if your doors run thicker than 1-3/4 inches. Both are mechanical privacy functions like the 8266.
16) I need a privacy mortise lock with a keypad or card reader instead of a thumbturn. What should I look at?
The 8266 is entirely mechanical, with no electronic components, so it will not do access control. For an electronic privacy mortise lock, the Schlage CO-100-MS-40-KP is a Grade 1 standalone with a keypad reader in privacy function for a 1-3/4 inch door. The Schlage LE Series LEBMB-ADD is a mobile-enabled mortise lock covering privacy, office and apartment functions, Grade 2, with a 3 hour fire rating.
17) The door is not prepped for a mortise pocket. What is the alternative to a Sargent 8266?
A cylindrical lock installs in bored holes rather than a routed mortise pocket. The Schlage PC10 is a Grade 1 passage cylindrical lock, non-keyed with rose, for 1-3/4 inch doors. The Sargent 8266 is a mortise lock and requires the door to be prepped for a mortise lock body, so on a bored door the cylindrical body is the one that fits the existing prep.
18) What is the difference between a Sargent 8266 with rose trim and a mortise lock with escutcheon trim?
Rose trim mounts on a small round plate around the lever; escutcheon trim uses a long plate covering more of the door face. The Sargent 8266 uses rose trim, offered in E rose at 3-1/16 inch, L rose at 3-1/2 inch, LN rose at 2 inch, and O rose at 2-3/4 inch. Among comparable mortise locks the choice runs both ways within one series: Hager's 3810S is the passage version with rose while the 3810E is the same passage function with escutcheon, both 2-3/4 inch backset. If the other doors in the building already carry escutcheons, that is the visual match to hold to.
19) Is a Baldwin 6301 mortise lock body a substitute for a Sargent 8266?
No. The Baldwin 6301 is an entrance/apartment function with a 2-1/2 inch backset, offered knob by knob or lever by lever for doors 1-3/4 inch and over, and the Baldwin 6310 is entrance/storeroom at the same 2-1/2 inch backset. The Sargent 8266 is a privacy bath/bedroom function on a 2-3/4 inch backset. Both the function and the backset differ, so the door prep and the way the lock behaves would not carry over.
20) Which mortise locks besides the Sargent 8266 are field reversible for handing?
The Sargent 8266 is field reversible, so one lock covers left or right hand without extra parts. Among comparables, the Falcon MA101 Grade 1 heavy duty mortise passage lock is field reversible, and the BEST 45H heavy duty mortise lock body in public entrance function offers field reversible operation. Others are handed at the factory - the Baldwin 6310190RRLS, for example, is specified as right hand reverse. On a job where the handing is not confirmed until the doors are hung, the reversible bodies are the safer stock item.
21) Does the Sargent 8266 come with a lever, or do I order the trim separately?
Lever trim is part of the order. You pick the lever design and the rose when you configure the lock, so it arrives as a complete lever-by-lever privacy set rather than a bare lock body. If what you actually want is just the mortise case, that is a different order; the BEST 45H Series, for example, is sold as a heavy duty lock body on its own.
22) Which finish on the Sargent 8266 matches the stainless and chrome hardware already in my facility?
For a stainless look, 32D satin stainless steel or 32 bright stainless. For chrome, 26D satin chrome over nickel is the common commercial choice, with 26 bright chrome as the polished version. Bronze and brass runs include 10B oil rubbed, 10BE, 10BL, 20D dark statuary, 03 bright brass, 04 satin brass, 09 bright bronze and 10 satin bronze. Nickel is 14 bright and 15 satin. There are also BSP black and WSP white suede powder coats for painted door programs.
