Sargent BP-8205 26D – Frequently Asked Questions

1) Will the Sargent BP8205 mortise lock body fit a 1-3/4 inch door?
Yes, 1-3/4 inches is exactly what the BP8205 lock body is built for, on a 2-3/4 inch backset mortise pocket. It is a single-thickness device, so thicker doors are outside what this body covers. Handing is field reversible, so one part number covers left and right hand openings and you don't have to pick handing on the order.
2) What does the Sargent 8205 office/entry function actually do at the door?
Office/entry is the function for a door somebody wants to leave unlocked during business hours and lock at close. The outside lever is locked or unlocked by the key from outside, the inside lever always retracts the latch for free egress, and it's a single cylinder lock, so there's no key on the room side. That's the standard choice for a tenant suite door, a shop door, or a staff office. If you need the outside lever locked at all times with key access only, a storeroom function such as the Cal-Royal NM8080 is the one to order instead.
3) I'm buying the BP8205 lock body only. What else do I need to order to finish the door?
The BP8205 is the mortise body alone. You still need trim (lever or knob with roses or escutcheons), a cylinder, and a strike to complete the opening. It ships with a curved lip strike specified as part of the Grade 1 listing, and it takes any SARGENT key system, so the cylinder gets ordered to whatever keyway your building runs. Sargent publishes an installation template covering the 7800 and 8200 bodies with all sectional rose and escutcheon trims, which is what your installer should be cutting the door from.
4) Will the Sargent 8200 mortise lock latch into the strike that's already in my frame?
The 8205 body throws a 3/4 inch latchbolt into a curved lip strike, which is the standard commercial mortise throw, so an existing ANSI mortise strike prep will normally take it. What decides it is the backset: this body is 2-3/4 inch. If the old lock was a 2-1/2 inch backset body (Baldwin's 6301 and 6310 bodies, for example, are 2-1/2 inch), the case pocket sits in a different place and the door has to be re-prepped.
5) Can I use the Sargent 8200 mortise lock on a fire rated door?
Yes. The 8200 Series is UL-cUL Fire-Rated up to 3 hours and carries UL 10C positive pressure certification, which is what a 3 hour opening in a stair or a corridor cross-wall needs. Office/entry function keeps the inside lever free for egress at all times, so it does not conflict with the egress requirement on a rated door.
6) Will the Sargent 8205 work with our existing master key system?
It works with all SARGENT key systems, Degree, Signature, KESO and XC included, so it drops into a Sargent masterkeyed facility without breaking the hierarchy. It's a single cylinder lock, so you're keying one cylinder per door, outside only. If your building is keyed to another manufacturer's system, that's a cylinder question, not a lock body question.
7) What is the closest cross-brand equivalent to the Sargent BP8205 mortise lock body for an office/entry opening?
The Cal-Royal NM8050 is a heavy duty Grade 1 mortise lockset with an Entrance/Office function and a 1-3/4 inch door thickness, which matches the Sargent BP8205 on grade, duty level and function. The difference is scope: the BP8205 is supplied as a lock body only, while the NM8050 is a complete lockset with an auxiliary deadlatch. If the door already has trim you intend to keep, the body-only route preserves it; if you are outfitting a bare door, the complete set is one line item.
8) I need a mortise lock body only, not a complete lockset - what other brands sell it that way?
BEST sells the 45H Series as a heavy duty mortise lock body with a Public Entrance function and field reversible operation, and the 45HCA Series as a heavy duty mortise lockbody with an Intruder function. Both are body-only like the Sargent BP8205, which is a heavy duty mortise body lock with an Office/Entry function. Baldwin also lists the 6301 as an Entry/Apartment mortise lock body on a 2-1/2 inch backset for doors 1-3/4 inch and over. Match the function first: Public Entrance and Entry/Apartment latch differently from Office/Entry.
9) What is the difference between an office/entry mortise lock and a storeroom mortise lock?
The Sargent BP8205 carries an Office/Entry function and is keyed as a single cylinder. Storeroom peers include the Accentra 8805FL, a Grade 1 storeroom mortise lock with an Arcadia lever from the 8800 Series, and the Cal-Royal NM8080, a heavy duty Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. Office/entry lets the occupant leave the outside lever unlocked for the business day; storeroom keeps the outside lever locked at all times so the key is required on every entry. Choose by whether the tenant needs to hold the door open to traffic.
10) Which mortise products look like substitutes for the Sargent BP8205 but will not lock the door?
Several mortise-labelled items are dummy trim and carry no latch or bolt: the Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan are all dummy-function mortise entrance locksets, and the Schlage L0170 is a Grade 1 heavy duty non-keyed half dummy trim for 1-3/4 inch doors. They mount for appearance and pull only. The Sargent BP8205 is a keyed single cylinder body with an Office/Entry function, so a dummy is only a match on an inactive leaf you never intend to secure.
11) My door is thinner than 1-3/4 inch - what mortise lock fits instead of the Sargent 8200 body?
The Sargent BP8205 is built for a 1-3/4 inch door. For thinner stock, the Baldwin 6310 is an Entry/Storeroom mortise lock body on a 2-1/2 inch backset rated for doors 1-3/8 inch and over, as is the 6310190RRLS right hand reverse lever version. Alarm Lock's DL2700CR classroom electronic mortise lock covers 1-5/8 to 1-7/8 inches. For ornamental iron stock at 1 inch, Marks USA lists the 21AC and 22AC entrance double cylinder mortise locks with a round knob. Measure the stile before you pick, since the backsets differ across these.
12) I need the mortise lock to release electrically on an access control system - what replaces the Sargent BP8205?
The BP8205 is a mechanical body with no electrical operation. Electrified mortise options include the Command Access ML190, a heavy-duty motorized mortise lock with field selectable EL/EU operation, 24VDC power and a storeroom function; the BEST 45HW, a heavy duty wired electromechanical mortise lock with 12V/24V operation; and the Schlage L9092EU with the 03A electric lock/unlock outside lever, keyed outside, request to exit, 12/24VDC, heavy duty, corridor function for 1-3/4 inch doors. Confirm fail safe versus fail secure against your egress requirement.
13) For a behavioral health or detention room, what mortise lockset should I specify rather than a standard office/entry body?
The Sargent BP8205 is a standard commercial Office/Entry body. Where ligature resistance is required, TownSteel lists the MRX-A-01, a Grade 1 heavy duty ligature resistant arch trim mortise lockset in satin stainless steel with a passage function for 1-3/4 inch doors, and the MRX-L-01, a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel, also passage, 1-3/4 inch. Marks USA offers the 5PDN, a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel. All three are passage function, so plan keying separately.
14) Are there Grade 2 mortise locks I might mistake for a Grade 1 replacement for the Sargent BP8205?
Yes, check the grade line before ordering. The Schlage Electronics LEBMB-ADD is a mobile-enabled mortise lock with push button and LED covering privacy, office and apartment functions, rated Grade 2 with a 3 hour fire rating for 1-3/4 inch doors, and the Dormakaba LX-I-M002 Saffire electronic RFID mortise lockset is BHMA Grade 2. The Sargent BP8205 is Grade 1 and heavy duty. If the spec on the drawing calls Grade 1, the LEMD-GRW ENGAGE Series wireless mortise lock with 125kHz proximity reader is the Grade 1 electronic option with a 3 hour fire rating.
15) Is the Sargent 8200 heavy enough for a high traffic entrance in an office building?
It's built for exactly that. Grade 1 heavy duty to ANSI/BHMA A156.13 Series 1000 Operational, and Sargent ran it through UL's Cycle Above and Beyond test to 16 million cycles (verification ID V584148). A156.13 Grade 1 only requires 1 million cycles, so 16 million is well past the bar for a main tenant entrance or a lobby door taking hundreds of swings a day.
16) Do I need to order the Sargent 8200 handed left or right?
No handing to specify. The 8205 body is field reversible, so the installer sets it at the door. For a property manager stocking spares across a building, that's one part number that fits every opening regardless of swing, which is worth more than it sounds when you're pulling a lock off the shelf at 7am.
17) Should I use a mortise lock like the Sargent 8200 or a cylindrical lockset?
A mortise body goes into a pocket routed into the door edge and carries far more mechanism, which is why it's the choice on heavy commercial entrances and why the 8200 tests to 16 million cycles. A cylindrical lock like the Schlage PC10 needs only a bored hole and is much faster to install or retrofit. If your doors are already mortise prepped, stay mortise. If they're bored, switching to mortise means re-prepping every door leaf, and that cost usually decides it.
18) Is there a cheaper Grade 1 office/entrance mortise lock than the Sargent 8200?
The Cal-Royal NM8050 is the closest straight equivalent we carry: Grade 1 heavy duty, entrance/office function, auxiliary deadlatch, for 1-3/4 inch doors, same as the Sargent. Where the Sargent pulls ahead is the key system side, since the 8200 body ties into Degree, Signature, KESO and XC, and the 16 million cycle test result. If neither of those matters on the opening, the Cal-Royal covers the same function on the same door thickness.
19) Is the Sargent BP8205 an electronic or access control lock?
No, the BP8205 is a mechanical, key operated body with no electronics in it. If you need credential access on the same door, the electrified route is a different part. For standalone keypad or card access on a mortise prep, look at the Dormakaba E-Plex 2066 pushbutton mortise lock, the Schlage CO-100 keypad mortise lock, or the TownSteel FME-2000 with RFID.
20) If the door does not need to be keyed, is there a simpler mortise lock than the Sargent BP8205?
Yes. The BP8205 is a keyed single cylinder body, so a non-keyed opening does not need it. The Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock 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, from the MA Series. Hager also lists the 3850E, a Grade 1 office mortise lock with lever and escutcheon, non-keyed, on a 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inches - that one holds the office function without the cylinder.
21) Can I use a keypad or credential mortise lock in place of the Sargent BP8205 to stop issuing keys?
The BP8205 is a mechanical, non-electronic body. Electronic mortise alternatives include the Alarm Lock DL3500CR, a Grade 1 Trilogy electronic mortise lock with 300 user codes and a classroom function for doors 1-5/8 to 1-7/8 inches; the Schlage CO-100, a Grade 1 heavy duty standalone electronic mortise lock with a keypad reader and privacy function for 1-3/4 inch doors; and the TownSteel FME-2000, a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors. Note the door thickness ranges differ across these, and each carries its own function rather than office/entry.
22) Is a mortise deadbolt an alternative to the Sargent BP8205 office/entry lock?
They do different jobs. The BP8205 is an Office/Entry mortise body with a latchbolt and a 3/4 inch throw. A mortise deadbolt such as the Kaba Ilco 185 Series, which is a no-handing deadbolt-function mortise lock, or the Alarm Lock DL4500, a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad for 1-5/8 to 1-7/8 inch doors, throws a bolt but does not give you a latching lever for everyday traffic. On an office door you generally want the latching body; a deadbolt is an addition to it, not a stand-in.
23) Which mortise locks match the Sargent BP8205 on ANSI Grade 1 for a facility standardizing on one grade?
Grade 1 peers across the mortise category include the Cal-Royal NM8050 in Entrance/Office, NM8070 in Classroom, NM8080 in Storeroom and NM8440 in Privacy, all for 1-3/4 inch doors; the Corbin Russwin ML2003 classroom in the ML2000 Series; the Falcon MA101 heavy duty passage with a fire rating; and the Schlage PM010 passage. The Sargent BP8205 is Grade 1 and heavy duty as well. That gives a single-grade schedule across office, classroom, storeroom, privacy and passage openings without dropping below Grade 1 anywhere.
24) The restroom needs privacy, not office/entry - what mortise lock covers that?
The Sargent BP8205 is keyed with an Office/Entry function, which is not what a restroom or bedroom wants. The Cal-Royal NM8440 is a heavy duty Grade 1 privacy mortise lockset with a 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 to 2 inches. Both hold the privacy function; the Hager backset matches the 2-3/4 inch the 8200 body uses, which helps if the frames were prepped to that dimension.
25) Can a tubular or narrow stile mortise latch replace the Sargent 8200 body on an aluminum glass door?
No. The Sargent BP8205 is a heavy duty Grade 1 mortise body for a 1-3/4 inch door. Aluminum and glass door openings are served by different products: the Alarm Lock DL1300NW is a Trilogy Networx wireless electronic mortise lock with a keypad made for Adams Rite deadlatches, the Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock for wide stile, and the Kaba Ilco BR Series is a glass door bottom rail lock. The Codelocks CL2255 is an electronic tubular mortise latch rated medium duty, a step down from heavy duty.
26) Is a cylindrical lock an acceptable substitute for a mortise lock body?
Not without changing the door prep. The Sargent BP8205 is a mortise lock type, which requires a pocket routed into the door edge. The Schlage PC10 is a Grade 1 passage cylindrical lock, non-keyed, with a rose for 1-3/4 inch doors, and it needs a bored hole instead. If the doors already carry a mortise pocket, staying mortise avoids re-prepping every leaf; the mortise counterpart in Schlage's non-keyed passage line is the PM010, also Grade 1 for 1-3/4 inch doors.
27) I want a mortise lock with a lever included rather than a bare body - which peers ship that way?
The Sargent BP8205 is supplied as a lock body. Peers that come with trim include the Accentra 8805FL, a Grade 1 storeroom mortise lock with an Arcadia lever; the Baldwin 6301LS, an Entry/Apartment lever by lever mortise lock body on a 2-1/2 inch backset for doors 1-3/4 inch and over; and the Hager 3850E, a Grade 1 office mortise lock with lever and escutcheon, non-keyed, on a 2-3/4 inch backset. Deciding factor is whether you are matching lever style to existing doors or replacing a whole set.
28) Which mortise locks let me keep a key override while adding a keypad, compared to the mechanical Sargent 8200 body?
The Sargent BP8205 is a mechanical keyed single cylinder body. If you want a keypad but still need a cylinder to fall back on, the BEST 45HZ EZ Series is an electronic keypad mortise lock with a key override function, and the Accentra NTM623-NR nexTouch Generation 3 mortise lock uses a capacitive touchscreen keypad with no deadbolt and cylinder override. The Dormakaba E5086 is a Grade 1 electronic pushbutton and card lock in a back to back mortise configuration for entry and egress.
29) What finishes does the Sargent 8200 mortise lock body come in?
Thirteen finishes: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B dark oxidized satin bronze oil rubbed, 10BL dark oxidized satin bronze clear coated, 15 satin nickel, 20D dark statuary bronze, 26 bright chrome, 26D satin chrome, 32 bright stainless, 32D satin stainless, and BSP black suede powder coat. If you're matching existing hardware in a commercial building, 26D and 32D are the two that cover most of it.
30) Can I change the function of a Sargent 8200 lock later without buying a new lock?
To a degree, yes. The 8200 lockbody is multifunctional and Sargent builds it for on-site function changes, and the series spans 56 functions including electromechanical, security and monitoring versions. For a facility standardizing on one platform across offices, classrooms and storerooms, that means one body family and one set of spare parts rather than a different lock for every door type.
31) What is the difference between the Hager 3810S and 3810E if I need a passage mortise lock on a thick door?
Both are Grade 1 passage mortise locks on a 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inches. The 3810S comes with a rose and the 3810E with an escutcheon, so the choice is trim coverage on the door face rather than a difference in the lock. Either is a passage function, unlike the Sargent BP8205, which is a keyed single cylinder Office/Entry body.
