Sargent 8289 LE1A 26D – Frequently Asked Questions

1) What does the holdback function on the Sargent 8289 mortise lock actually do?
Holdback means the latchbolt can be held retracted so the door stays free-swinging until you release it, then the lock returns to keyed operation. Sargent lists the 8289 as a single-cylinder keyed holdback lock with lever trim, so one cylinder controls it from one side. It is a mechanical lock, not an electrified one, so nothing about the holdback depends on power.
2) Is a 3/4 inch latchbolt throw enough to work with my existing ANSI strike?
The 8289-ET throws its latchbolt 3/4 inch, which is the normal projection for a commercial mortise latch and works with a standard ANSI/BHMA mortise strike in a hollow metal frame. If the frame is already prepped for another 8200 Series lock, the strike and lip location carry over.
3) Do I have to order the Sargent 8289-ET handed?
No. The lock body is field reversible, so the same unit covers left and right hand openings and one part number can cover a run of doors swinging both ways.
4) What do I need to specify when ordering the 8289-ET besides the function?
Four choices. Escutcheon style, LE1, LS, LW1 or WT. Lever design, A, B, E, F, J, L, P or W. Finish, sixteen options from 03 bright brass through 32D satin stainless and BSP or WSP suede powder coats. And cylinder handling, which is where keying gets decided.
5) Can I get the Sargent 8289-ET prepped for my own interchangeable cores?
Yes. Alongside a standard cylinder, the 8289-ET can be ordered as 70 for small format interchangeable core prep less core, or 60 for large format interchangeable core prep less core. There is also a straight less cylinder option if you are supplying the cylinder yourself. Pick None on keying when you order less cylinder, otherwise choose keyed different, keyed alike, or supply a key code.
6) Will this lock work on our existing Sargent master key system?
It integrates with all SARGENT key systems, including Degree, Signature, KESO and XC, so it can be keyed into an existing Sargent hierarchy rather than standing alone. For a facility standardizing keying, order keyed alike or supply your key code.
7) Is the Sargent 8289 mortise lock fire rated and ADA compliant?
Both. It is UL 10C fire rated up to 3 hours with positive pressure certification, and the lever trim is ADA compliant. Grade is ANSI/BHMA A156.13 Series 1000 Operational Grade 1.
8) My doors are thicker than 1-3/4 inches. Is there a mortise lock that covers that range?
The 8289-ET is specified at 1-3/4 inch door thickness. For thicker doors, Hager's 3800 Series covers 1-3/4 inch to 2-1/2 inch: the 3810E passage with escutcheon and the 3850E office with lever and escutcheon both list that range with a 2-3/4 inch backset. Note those are passage and office functions, not holdback.
9) What is the closest Grade 1 mortise lock to the Sargent 8289-ET if the opening needs a storeroom function instead of holdback?
The Sargent 8289-ET is a Grade 1 mortise lock built around a holdback function with a single keyed cylinder. For a storeroom opening, the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. Both keep the mortise pocket and Grade 1 rating while changing the lock function at the lever.
10) Which mortise lock should I use instead of the Sargent 8289-ET on a classroom door?
The Sargent 8289-ET is a holdback function lock, which is not a classroom function. For classroom openings the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors in the ML2000 Series, and the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset for 1-3/4 inch doors with an auxiliary deadlatch. Both are mechanical like the 8289-ET.
11) Is the Schlage L0170 an equivalent to the Sargent 8289-ET?
No. The Schlage L0170 is a Grade 1 heavy duty non-keyed dummy trim in the L Series for 1-3/4 inch doors, so it provides no latching or key control at all. The Sargent 8289-ET is a keyed single cylinder Grade 1 holdback mortise lock. The two look similar on the door face but only one secures the opening.
12) What looks like a substitute for the Sargent 8289-ET but will not work in a mortise pocket?
The Schlage PC10 is a Grade 1 passage cylindrical lock with a rose for 1-3/4 inch doors. It is a bored cylindrical prep, not a mortise pocket, so it is not an exchange for the Sargent 8289-ET mortise lock. Falcon's MESC600DT is another one to rule out - it is dummy escutcheon lever trim for M9900 Series exit devices rather than a mortise lock body.
13) For a behavioral health or anti-ligature opening, what replaces the Sargent 8289-ET lever escutcheon trim?
The Sargent 8289-ET uses lever handles on escutcheon trim, which is not a ligature-resistant profile. For those rooms, the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel in passage function for 1-3/4 inch doors, the MRX-A-01 is the same passage function with ligature-resistant arch trim, and the Marks USA 5PDN is a Grade 1 ligature-resistant hospital passage mortise push/pull paddleset in satin stainless steel.
14) How durable is this lock for a high-traffic entrance?
Heavy duty rating, with the UL Cycle Above and Beyond test completed at 16 million cycles under verification ID V584148. For a main corridor or a school entry that sees constant use, that cycle count is the number to compare against.
15) Should I use escutcheon trim or sectional rose trim on my mortise locks?
Escutcheon trim is a full plate that covers more of the door face, which helps when you are hiding an older prep or scars from previous hardware, and it is what the 8289-ET carries. Sectional rose trim is smaller and leaves more of the door showing. Both prep from the same 7800/8200 Series mortise template, so the choice is aesthetic and cover, not pocket geometry.
16) Can this Sargent lock be switched to a different function later, or do I have to buy a new lock?
The 8200 lock body is multi-functional, offered across 56 functions including electromechanical, security and monitoring versions, with on-site function switching. That means a 8289 body can be reconfigured in the field rather than replaced when a room's use changes, which matters if you are standardizing a building on one lock body.
17) What prep do I need to cut in the door before installing the 8289-ET?
A routed mortise pocket plus the face bores for the escutcheon and lever spindle, laid out from the Sargent 7800 and 8200 Series template that covers sectional rose and escutcheon trims. Prep to 1-3/4 inch door thickness and a 2-3/4 inch backset, then set the strike so the 3/4 inch latchbolt seats fully.
18) The Sargent 8289-ET is specified for a 1-3/4 inch door. What mortise lock covers a thicker door?
The 8289-ET is built for 1-3/4 inch door thickness. Where the door is thicker, the Hager 3810E passage mortise lock and Hager 3850E office mortise lock both list a 1-3/4 to 2-1/2 inch door thickness range on a 2-3/4 inch backset, and the Baldwin 6301LS lever by lever mortise lock body lists 1-3/4 inch and over on a 2-1/2 inch backset. Note that those are passage, office and entrance/apartment functions rather than holdback.
19) I need an escutcheon trim mortise lock but the door does not need a key. What is a non-keyed alternative to the Sargent 8289-ET?
The 8289-ET is keyed with a single cylinder. If the opening does not need keying but you still want lever-and-escutcheon trim on a mortise pocket, the Hager 3850E is a Grade 1 non-keyed office mortise lock with lever and escutcheon on a 2-3/4 inch backset for 1-3/4 to 2-1/2 inch doors, and the Hager 3810E is a Grade 1 passage mortise lock with escutcheon on the same 2-3/4 inch backset.
20) Can I swap the Sargent 8289-ET for an electronic mortise lock and keep the same door prep expectations?
The 8289-ET is a mechanical, non-electronic Grade 1 mortise lock. If the opening is moving to credentials, the TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors, the Schlage CO-100-MS-40-KP is a Grade 1 heavy duty standalone electronic mortise lock with a keypad reader in privacy function for 1-3/4 inch doors, and the Dormakaba E-Plex E5086 is a Grade 1 electronic pushbutton and card mortise lock in entry/egress configuration. These change the credential and the power requirement, not the mortise body approach.
21) If I only need a bare mortise lock body rather than the Sargent 8289-ET's complete escutcheon trim package, what are my options?
The Sargent 8289-ET ships as a holdback function escutcheon trim set with the mortise lock body, offered in LE1, LS, LW1 and WT escutcheons. If you already have trim on the door and need the body alone, the BEST 45HCAC is a heavy duty mortise lock body in public entrance function with field reversible operation, and the BEST 45HCAINL is a heavy duty mortise lockbody with intruder function.
22) Is there an electrified mortise lock alternative to the Sargent 8289-ET for access control tie-in?
The 8289-ET is a mechanical lock with no electrical components. For an access control tie-in on a mortise prep, the BEST 45HW is a heavy duty wired electromechanical mortise lock with 12V/24V operation, the Command Access ML190 is a heavy-duty motorized mortise lock in storeroom function with field selectable EL/EU operation on 24VDC, and the Schlage L9092EU with 03A lever is a heavy duty electric lock/unlock mortise lock keyed outside with request to exit on 12/24VDC for 1-3/4 inch doors.
23) How does the Sargent 8289-ET compare to the Cal-Royal NM8050 for an office entrance door?
Both are Grade 1 mortise locksets for commercial openings. The Cal-Royal NM8050 is a heavy duty Grade 1 office/entrance mortise lockset with an auxiliary deadlatch for 1-3/4 inch doors. The Sargent 8289-ET is a heavy duty Grade 1 holdback function lock with a single keyed cylinder, escutcheon trim in LE1, LS, LW1 or WT, and a choice of A, B, E, F, J, L, P or W levers. The function at the lever is the deciding difference.
24) Will the finish on the Sargent 8289-ET match the other lever sets in my building?
Sixteen finishes are offered, covering the common commercial choices: 26D satin chrome, 32D satin stainless, 15 satin nickel, 10B oil rubbed dark bronze, 04 satin brass, plus 03, 09, 10, 10BE, 10BL, 14, 20D, 26, 32, and black or white suede powder coat. Match the BHMA finish number on your existing hardware and order the same code.
