Sargent 8250 EA 26D – Frequently Asked Questions

1) Will the Sargent 8250 hotel lock work on a 1-3/4 inch door?
Yes. The 8250 mortise lock is built for 1-3/4 inch door thickness with a 2-3/4 inch backset, which is the standard commercial prep. If your doors are thicker than 1-3/4 inches, this is not the right lock body for them.
2) What does hotel guest function actually do on the Sargent 8250?
It's the classic guest room setup: the lever is locked from outside and opened by the guest key, with a single cylinder deadbolt for privacy from inside. When the deadbolt is thrown, standard guest keys are shut out. The lock body is keyed with a single cylinder configuration and takes a lever trim.
3) Do I need to order the Sargent 8250 handed?
No. The 8250 lock body is field reversible, so one part number covers left and right hand openings and you set the handing at install. That makes it easier to stock a single lock for a whole floor of guest rooms.
4) Can I put the Sargent 8250 on a fire rated guest room door?
Yes. The 8250 is UL 10C fire rated up to 3 hours and NFPA 80 compliant, and it carries ANSI/BHMA A156.13 Series 1000 Operational Grade 1. It's also ADA compliant, which the lever trim supports.
5) Will the 8250 latch into the strike already in my frame?
The 8250 uses a 3/4 inch latchbolt throw off a 2-3/4 inch backset mortise body. If the frame is prepped to standard ANSI mortise strike dimensions, it will engage. If you're replacing an older non-ANSI mortise lock, check the existing strike cutout before you pull the old body.
6) What do I have to specify when ordering a Sargent 8250?
Four choices plus keying. Cylinder: standard cylinder, less cylinder, 70 for small format interchangeable core prep less core, or 60 for large format IC prep less core. Keying: keyed different, keyed alike, or to a key code (pick None if you ordered less cylinder). Then lever style A, B, E, F, J, L, P or W, rose style E at 3-1/16 inch, L at 3-1/2 inch, LN at 2 inch or O at 2-3/4 inch, and one of 16 finishes.
7) Can the Sargent 8250 go on our existing master key system?
It integrates with all Sargent key systems, including Degree, Signature, KESO and XC. Order it with a standard cylinder if you want Sargent to supply the cylinder, or specify the 70 or 60 prep less core if your locksmith is stuffing your own small or large format interchangeable cores. Less cylinder is also available if you're reusing existing cylinders.
8) What is the closest Grade 1 mortise storeroom lock to the Sargent 8250 if the opening does not need a hotel guest function?
The Sargent 8250 is a Grade 1 mortise lock built specifically as a hotel guest lock with a single cylinder deadbolt. For a back-of-house or service door that only needs key-in, always-locked outside operation, 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 drop the guest-room deadbolt behavior of the 8250 and give you a straight storeroom function instead.
9) If I want credential-based guest room access rather than a keyed hotel lock, what mortise locks replace the Sargent 8250?
The Sargent 8250 is a mechanical, non-electronic keyed mortise lock. If the property is moving guest rooms to cards or mobile credentials, the Dormakaba Saffire LX-I-M002 is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2, and the Dormakaba E-Plex E5086 is a Grade 1 electronic pushbutton and card back-to-back mortise lock. The Accentra NTM623-NR nexTouch Generation 3 mortise lock uses a capacitive touchscreen keypad with no deadbolt and cylinder override, so note that it gives up the deadbolt the 8250 carries.
10) The Sargent 8250 description mentions 12 to 24VDC electromechanical options - what dedicated electrified mortise locks compare?
The Sargent 8250 8200 Series family includes electromechanical functions operating from 12 to 24VDC with EcoFlex technology. If you are specifying an electrified mortise lock outright, the BEST 45HW is a heavy duty wired electromechanical mortise lock with 12V/24V operation, 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, and the Command Access ML190 is a heavy-duty motorized storeroom mortise lock with field selectable EL/EU operation at 24VDC.
11) Is the Sargent 8250 an electronic lock or a mechanical one?
As ordered here it's a mechanical mortise lock, not an electronic one. The 8200 Series does offer electromechanical functions that run on 12 to 24VDC with EcoFlex power management, but the 8250 hotel guest lock configuration is mechanical with a key cylinder and deadbolt. If you need card or credential access on guest rooms, look at an electronic mortise platform instead, such as the Dormakaba Saffire LX-I-M002 RFID mortise lockset.
12) Which rose size should I pick for the 8250, and does it matter for covering old holes?
Four rose diameters 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. If you're retrofitting over a door face with old trim marks or an oversized prep, the L rose at 3-1/2 inches gives you the most coverage. LN is the smallest and shows the least hardware on the door.
13) How durable is the Sargent 8250 for a high traffic hotel corridor?
It's a heavy duty Grade 1 commercial lock, and Sargent completed UL's Cycle Above and Beyond test at 16 million cycles on this platform (Verification ID V584148). For guest rooms turning over daily, that cycle count is the number to hold against anything else you're comparing.
14) I need a Grade 1 mortise lock but for a classroom or storeroom, not a guest room. What should I look at instead?
The 8250 is specifically a hotel guest function with deadbolt, so it's the wrong pick for a classroom or storeroom door. For classroom function, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors, and the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset. For storeroom, look at the Accentra 8805FL or the Cal-Royal NM8080, both Grade 1 storeroom mortise locks.
15) Is there a Grade 1 mortise lock with a deadbolt for apartments or dorms rather than hotel rooms?
The 8250's hotel guest function assumes a front desk key hierarchy. For a privacy deadbolt application on multi-family or dorm doors, the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors. If you want keypad control on the deadbolt instead of keys, the Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with privacy keypad and 2,000 user codes.
16) My doors are thicker than 1-3/4 inches. Can I still use the Sargent 8250?
No. The 8250 is specified at 1-3/4 inch door thickness. For thicker doors, the Hager 3800 Series Grade 1 mortise locks cover 1-3/4 to 2-1/2 inches with a 2-3/4 inch backset, though those are passage and office functions rather than hotel guest.
17) What mortise lock gives me privacy with a deadbolt like the Sargent 8250 but for a residential or bath door?
The Sargent 8250 pairs a lever with a single cylinder deadbolt for guest room use, which means key access from outside. Where the door only needs occupant-controlled privacy, 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 with a 2-3/4 inch backset for doors 1-3/4 inch to 2 inch. Both are privacy function rather than keyed entry, so there is no outside cylinder to key into a master system.
18) Which mortise products look like a substitute for the Sargent 8250 but will not secure a guest room door?
Several mortise items sit close in the catalog but do not lock. The Schlage L0170 is a Grade 1 heavy duty half dummy trim with no latch or bolt, and the Emtek 3102 Memphis, 3104 Hamilton, 3106 Manhattan and 3019 Brisbane mortise entrance locksets are dummy function. Passage-only options such as the Falcon MA101 Grade 1 heavy duty mortise passage lock and the Schlage PM010 Grade 1 passage latch mortise lock latch the door but are non-keyed. The Sargent 8250 is a keyed hotel guest lock with a single cylinder deadbolt, so none of these are a security equivalent.
19) Is there a simpler way to get Grade 1 mortise entry on an apartment or multi-tenant door instead of the Sargent 8250?
The Sargent 8250 is a hotel guest function lock with 56 functions and a deadbolt, which is more lock than a plain tenant entry door usually needs. The Cal-Royal NM8050 is a heavy duty Grade 1 office/entrance mortise lockset with auxiliary deadlatch for 1-3/4 inch doors. For an entrance/apartment function on thicker doors, the Baldwin 6301LS is a lever by lever mortise lock body with a 2-1/2 inch backset for doors 1-3/4 inch and over, with the 6301 offering the same function in knob by knob. Note the Baldwin backset is 2-1/2 inch against the 2-3/4 inch backset of the 8250, so the door prep differs.
20) For a behavioral health or dormitory door where the Sargent 8250 lever is a concern, what mortise locks work instead?
The Sargent 8250 uses lever trim, available in A, B, E, F, J, L, P and W lever styles. Where ligature resistance governs, 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 ligature resistant, ADA compliant hospital passage mortise push/pull paddleset in satin stainless steel. All three are passage function, so plan a separate locking method where security is required.
21) I need a standalone keypad mortise lock rather than the keyed Sargent 8250 - what are the options?
The Sargent 8250 is a mechanical keyed lock, not electronic. For standalone keypad control on a mortise prep, the Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes and classroom function for doors 1-5/8 inch to 1-7/8 inch, and the DL2700CR is a Trilogy T2 Grade 1 classroom electronic mortise lock with weatherproof design for the same door thickness range. The Schlage CO-100-MS-40-KP is a Grade 1 heavy duty standalone electronic mortise lock in privacy function with a keypad reader for 1-3/4 inch doors, and the BEST 45HZ EZ Series is an electronic keypad mortise lock with key override.
22) If I only need the mortise lock body and not the trim the Sargent 8250 includes, what can I order?
The Sargent 8250 is supplied as a complete lockset with lever and rose trim, offered in E, L, LN and O roses. When the existing trim is staying and only the case is being replaced, the BEST 45HCA public entrance mortise lock body is a heavy duty lock body with field reversible operation, and the 45HCAINL is a heavy duty mortise lockbody in intruder function. Baldwin 6310 is an entry/storeroom mortise lock body with a 2-1/2 inch backset for doors 1-3/8 inch and over.
23) What is the difference between the Sargent 8250 and a mortise deadbolt like the Kaba Ilco 185 or Alarm Lock DL4500?
The Sargent 8250 combines lever-operated latch and a single cylinder deadbolt in one mortise case, so one prep handles both latching and bolting. The Kaba Ilco 185 Series is a deadbolt-function mortise lock with no handing required, and the Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad for doors 1-5/8 inch to 1-7/8 inch. Both are bolt-only, so the door still needs a separate latch or pull to keep it closed.
24) What finishes can I get the Sargent 8250 in to match the rest of the property?
Sixteen finishes: 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, plus BSP black suede and WSP white suede powder coat. 26D and 32D are the usual choices when you're standardizing across a building.
25) Can I use a cylindrical lock instead of the Sargent 8250 mortise lock?
Only if the door is prepped for it. The Sargent 8250 is a mortise lock requiring a mortise pocket in the door edge, while the Schlage PC10 is a Grade 1 passage cylindrical lock with rose for 1-3/4 inch doors and uses a bored prep instead. The two preps are not interchangeable, and the PC10 is non-keyed passage function rather than the keyed hotel guest function of the 8250.
