Sargent 485 26D – Frequently Asked Questions

1) Will the Sargent 485 deadbolt latch into the strike already in my frame?
The bolt throws a full 1 inch of hardened steel, which is deeper than most residential-grade bolts, so the existing strike pocket has to be deep enough to take it. Two strikes are offered: the 404 at 2-3/4 inches for a standard wood-frame prep, and the 408 ANSI 4-7/8 inch flat lip strike for a commercial hollow metal frame already cut to ANSI prep. Order the 408 if your frames are ANSI prepped and you want a drop-in replacement.
2) Can I get the Sargent 485 deadbolt keyed into our existing Sargent master key system?
Yes. The 485 takes a 6-pin brass cylinder that is rekeyable and works with Sargent masterkey systems, and you choose the keyway when ordering: LA is the standard, with the full CA/CB/CC/CE/CF/CG/CJ/CK/CL/CR, HA through HK, LB through LL, R, RA through RL, S and U keyways available. Keying is specified as standard keying, KD keyed different, or KA keyed alike.
3) Can I order the Sargent 485 deadbolt without a cylinder so I can pin it myself?
Yes. Cylinder is a required selection and LC (less cylinder) is one of the choices, which is how most locksmiths order it when they are pinning to house keyways. The other options are a 6-pin standard cylinder, 60 for Sargent large format interchangeable core with a plastic disposable construction core, and 70 for small format interchangeable core with a construction core. The 60 and 70 options ship with a construction core so the door is secure during the build, then you drop in the permanent core at turnover.
4) Is the Sargent 485 a Grade 1 deadbolt, and does that matter for a school or hospital spec?
ANSI/BHMA Grade 1 certified, which is the highest of the three commercial grades and what most institutional specs call for on exterior and high-traffic openings. The 485 backs that up with a steel-reinforced case and a hardened, anti-saw bolt. Among the alternatives, several common deadbolts are Grade 2 or Grade 3 (the Arrow DBX61 and Cal-Royal CB160 are Grade 2, the Cal-Royal LSD is Grade 3), so if the drawing says Grade 1 those will not meet it.
5) Single cylinder or double cylinder deadbolt for a commercial exit door?
The Sargent 485 is single cylinder: key outside, thumbturn inside. That thumbturn is what lets someone leave without a key, which is what most egress codes want on an occupied exit. A double cylinder needs a key on both sides and is usually chosen where there is glass next to the lock, at the cost of that free egress. If you need double cylinder, the Design Hardware D1 Series is a Grade 1 double cylinder deadbolt for 1-3/4 inch doors, and the Dexter DB1000 double cylinder is Grade 1 for 1-3/8 to 1-7/8 inch doors.
6) What is the closest Grade 1 single cylinder deadbolt to a Sargent 485 if I need one on a 1-3/8 inch door?
The Sargent 485 is a Grade 1 cylinder x thumbturn deadbolt built for 1-3/4 inch to 2 inch doors, so a 1-3/8 inch leaf falls below its range. The Dexter DB1000 single cylinder deadbolt is also Grade 1 cylinder x thumbturn and covers 1-3/8 inch to 1-7/8 inch doors, and the Accentra D111 is Grade 1 cylinder x thumbturn for 1-3/8 inch to 1-3/4 inch. Either one keeps the Grade 1 rating on the thinner door.
7) Is a Grade 2 deadbolt like the Hager 3215 an acceptable substitute for the Sargent 485?
They are not the same rating. The Sargent 485 is ANSI/BHMA Grade 1 heavy duty with a 1 inch throw hardened steel bolt and steel-reinforced case. The Hager 3215 is a Grade 2 cylinder x thumbturn deadbolt with a 1 inch throw for 1-3/8 inch to 1-3/4 inch doors and carries a fire rating. If your specification calls out Grade 1, the 3215 will not satisfy it; if the drawing calls for Grade 2 and a fire rating on a thinner door, the Hager is the one that matches.
8) What Grade 1 deadbolt should I use when the room needs a classroom function instead of a plain thumbturn?
The Sargent 485 is a cylinder x thumbturn deadbolt, so the inside turn always retracts the bolt. Where the opening needs classroom function, the Falcon D111 is a Grade 1 heavy duty classroom deadbolt with an adjustable backset, and the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and 6-pin cylinder for 1-3/8 inch to 1-3/4 inch doors. Both keep the Grade 1 rating while changing how the room side behaves.
9) Do I have to order a Sargent 485 deadbolt for left hand and right hand doors separately?
No. The 485 is non-handed and reversible, so one part number covers both swings. For a property manager stocking spares across a building, that means a single SKU per finish and backset instead of two.
10) Is there a Grade 1 deadbolt that works on both 1-3/4 inch and thicker doors if my building has a mix?
The 485 tops out at 2 inches, so it covers 1-3/4 to 2 inch doors but nothing thinner. If a building has both thin and thick leaves, no single 485 order covers it. For thicker openings the Corbin Russwin DL3011 Grade 1 cylindrical deadlock is rated 1-3/4 to 2-1/4 inches, and for thin leaves the Accentra D111 Grade 1 handles 1-3/8 to 1-3/4 inches. Measure the leaves before standardizing.
11) What do I have to specify when ordering a Sargent 485 deadbolt?
Five things get picked on the order: cylinder (6-pin standard, 60 large format IC, 70 small format IC, or LC less cylinder), keying (standard, KD, or KA), keyway (LA standard or any of the other 39 Sargent keyways), backset (2-3/8 or 2-3/4 inch), finish, and strike (404 standard or 408 ANSI). Cylinder and keying are required selections; keyway defaults to LA if you do not call one out.
12) Is a Sargent 485 overkill for an interior office door?
Probably, yes. The 485 is a heavy duty, commercial Grade 1 deadbolt with a hardened anti-saw bolt, built for exterior and high-abuse openings. On a low-traffic interior door a Grade 2 or Grade 3 deadbolt does the job: the Arrow DBX61 is Grade 2 cylinder x thumbturn, and the Cal-Royal ED500 is Grade 3 with an adjustable backset for 1-3/8 to 1-3/4 inch doors. Keep the 485 where the door is taking real force or real cycle counts.
13) Can I use a Sargent 485 deadbolt on a door that needs an interchangeable core?
Yes, and you pick which core system at the order. Option 60 preps the 485 for Sargent large format interchangeable core (FSIC) and 70 preps it for small format (SFIC); both ship with a plastic disposable construction core so the opening locks during construction and the permanent core drops in later without pulling the deadbolt off the door. If the facility is already standardized on SFIC, the Deltana CL200LAIC is a Grade 2 interchangeable core deadbolt, and the Arrow E61 is a Grade 2 SFIC-prep deadlock supplied less core.
14) I need a deadbolt with no key at all on the inside room side for an exit door. Will the Sargent 485 work?
No. The Sargent 485 is keyed with a single cylinder outside and a thumbturn inside. For an exit opening that takes no cylinder, the Arrow E60 is a Grade 2 exit deadlock, non-keyed, blank plate x thumbturn for 1-3/8 inch to 1-3/4 inch doors. For a Grade 1 cylinder x blank deadlock the Corbin Russwin DL3011 is a cylindrical deadlock for 1-3/4 inch to 2-1/4 inch doors.
15) What Grade 1 alternative to the Sargent 485 ships less core for an interchangeable core keying system?
The Sargent 485 can be ordered LC less cylinder or with a Sargent large format FSIC or small format SFIC construction core, which keeps it inside Sargent keying. If the facility keys a different system, the Delaney LM Series is a Grade 1 single cylinder less core deadbolt in dull chrome US26D. The Arrow E61 26D IC is a Grade 2 single cylinder deadlock with SFIC prep less core for 1-3/8 inch to 1-3/4 inch doors.
16) Is the Cal-Royal CRB800 the same thing as a Sargent 485?
They are close in intent but differ in what is stated. Both are heavy duty single cylinder cylinder x thumbturn deadbolts, and the Sargent 485 is ANSI/BHMA Grade 1 with a 1 inch throw hardened steel bolt for 1-3/4 inch to 2 inch doors. The Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch. Where the opening is a rated door assembly, the CRB800 is the one carrying the UL 3-hour callout.
17) For light traffic interior doors, is there a simpler deadbolt than the Sargent 485?
The Sargent 485 is a Grade 1 commercial heavy duty deadbolt sized for 1-3/4 inch to 2 inch doors. Where the opening does not need that, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with adjustable backset for 1-3/8 inch to 1-3/4 inch doors, and the Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn over the same thickness range. Both are cylinder x thumbturn like the 485.
18) The door already has a mortise lock body. Can I order a Sargent 485 for it?
No. The Sargent 485 is a bored deadbolt with its own 2-3/8 inch or 2-3/4 inch backset prep and a 404 or 408 strike. For a mortise case the Dormakaba D900 small case mortise deadbolt is a cylinder x thumbturn mortise deadbolt, and the Arrow 460 is a mortise lock strike covering latchbolt and deadbolt functions with a straight lip for 1-3/4 inch doors.
19) What deadbolt do I use instead of the Sargent 485 if the opening needs code entry rather than a key?
The Sargent 485 is a keyed mechanical deadbolt with a single cylinder outside. For credential or code access, the Codelocks CL200 is a surface deadbolt with key override at a light duty level, the Codelocks CL2200 is an electronic surface deadbolt in brushed steel at a medium duty level, and the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote. The DynaLock 1300 Series is a heavy duty mortise electric deadbolt for access control tie-in.
20) Can I substitute a Falcon H2101 for a Sargent 485 on an apartment entry?
They do different jobs on the door. The Sargent 485 is a standalone Grade 1 deadbolt with cylinder outside and thumbturn inside, installed alongside whatever latchset is already there. The Falcon H2101 is a Grade 2 entrance interconnected lock with a single cylinder deadbolt, meaning the deadbolt and the knob or lever retract together as one unit and the door prep is different. Choose the H2101 only if you are replacing both functions with an interconnected set.
21) Which single cylinder deadbolt should I standardize on across a facility with mixed door thicknesses?
The Sargent 485 covers 1-3/4 inch to 2 inch doors at Grade 1 with a non-handed reversible design, so it handles the thicker commercial leaves. Doors thinner than that need a different body: the Deltana 7312KA2 spans 1-3/8 inch to 2 inch at Grade 3, and the Dexter DB1000 single cylinder spans 1-3/8 inch to 1-7/8 inch at Grade 1. Pairing the 485 on the 1-3/4 inch and heavier openings with the Dexter DB1000 on the thinner ones keeps Grade 1 across the whole building.
22) What finishes does the Sargent 485 deadbolt come in to match the other hardware in the building?
Twelve finishes: 03 bright brass and 04 satin brass, both clear coated; 09 bright bronze and 10 satin bronze, clear coated; 10B dark oxidized satin bronze oil rubbed and 10BE dark oxidized satin bronze; 14 bright nickel and 15 satin nickel, clear coated; 26 bright chrome and 26D satin chrome over nickel; plus BSP black suede and WSP white suede powder coat. 26D is the usual commercial default, and the BSP and WSP powder coats are there when the openings are painted-out storefront or dark aluminum.
23) Which deadbolt matches a Sargent 485 in function but comes in a decorative trim for a front entrance?
The Sargent 485 is a commercial cylinder x thumbturn deadbolt offered in twelve finishes including 10B dark oxidized satin bronze and 26D satin chrome. For decorative openings the Emtek #11 Tuscany lost wax cast bronze deadbolt is cylinder x thumbturn, and the Bravura 310RC Elite and 310SC Elite are Grade 2 cylinder x thumbturn deadbolts in contemporary round and square trim. These change the appearance of the rose, not the basic keyed outside, turn inside operation.
24) I picked a Baldwin 8BR0618001 thinking it was a deadbolt replacement. Is it?
It is not a lock. The Baldwin Reserve 8BR0618001 is a deadbolt spacer for a double cylinder application, and the BEST 8T is a tubular deadbolt tube component from the T Series. Neither one is a complete keyed deadbolt. The Sargent 485 is a full Grade 1 single cylinder deadbolt with cylinder, bolt, thumbturn and strike.
