Sargent 484 26D – Frequently Asked Questions

1) Does the Sargent 484 need a key on the inside too, or is there a thumbturn?
Key both sides. The 484 is a double cylinder deadbolt, meaning 6-pin brass cylinders keyed inside and out with no thumbturn. That is what you want on a glass-front or sidelite opening where someone could reach through and turn a knob, but many jurisdictions restrict key-both-sides bolts on required egress doors. If you need key outside and turn inside, that is a different function.
2) Which strike should I order with a Sargent 484 deadbolt, the 404 or the 408?
Two strikes are offered and the frame decides it. The 404 is a 2-3/4 inch standard strike, which suits a wood frame or an existing residential-style prep. The 408 is the ANSI 4-7/8 inch flat lip strike, which is the one that drops into a hollow metal frame already cut to the ANSI 4-7/8 inch mortise, and it is what most commercial jobs want. Pick the 408 if you are replacing hardware in an existing HM frame and don't want to file or re-prep the jamb.
3) Can I get the Sargent 484 deadbolt on our existing master key system?
Yes, and it's the main reason to buy this one. The 484 takes 6-pin brass cylinders with masterkeying capability, and you pick the keyway when you order: LA is standard, with CA, CB, CC, CE, CF, CG, CJ, CK, CL, CR, HA, HB, HC, HE, HF, HG, HH, HJ, HK, LB, LC, LE, LF, LG, LJ, LK, LL, R, RA, RB, RC, RE, RF, RG, RJ, RK, RL, S and U also available. Keying is specified as keyed different or keyed alike. Match the keyway to whatever your Sargent system already runs and the locksmith can pin it into the existing hierarchy.
4) Can I order the Sargent 484 without cylinders so our locksmith can supply them?
Yes. Cylinder choice is a required selection and LC (less cylinder) is one of the options, which ships the deadbolt prepped but without cylinders so your locksmith drops in cores from your own system. The other choices are a 6-pin standard cylinder, or interchangeable core prep with a disposable plastic construction core: 60 for Sargent large format (FSIC) or 70 for small format (SFIC). The construction core options are what you want on new construction, so trades can be locked out at turnover by swapping to permanent cores instead of rekeying.
5) What other Grade 1 double cylinder deadbolts could I use instead of the Sargent 484?
The closest straight equivalent is the Design Hardware D1 Series double cylinder deadbolt, Grade 1 and rated extra heavy duty, though it is a single door thickness at 1-3/4 inches rather than the 484's 1-3/4 to 2 inch range. The Dexter DB1000 double cylinder is also Grade 1 and covers 1-3/8 to 1-7/8 inch doors, so it reaches down to thinner doors the Sargent will not. The reason to stay with the 484 is keying: it takes Sargent 6-pin cylinders across 40 keyways plus FSIC and SFIC core prep, so it drops into an existing Sargent masterkey system.
6) Our doors are 1-3/8 inch. What double cylinder deadbolt should I use instead of the Sargent 484?
The 484 is out at that thickness, since it starts at 1-3/4 inches. For 1-3/8 inch doors, the Dexter DB2000 double cylinder covers 1-3/8 to 1-3/4 inch at Grade 2, and the Delaney LU Series double cylinder is another Grade 2 option. If you want the widest thickness coverage, the Deltana 7312KA2 double cylinder runs 1-3/8 to 2 inches, though it is Grade 3. None of these is a Grade 1 replacement, so if the spec calls Grade 1 you will need to change the door prep rather than the lock.
7) What do I actually have to specify when ordering a Sargent 484 deadbolt?
Four decisions. Cylinder type is required: 6-pin standard, 60 for Sargent large format IC with construction core, 70 for small format IC with construction core, or LC less cylinder. Keying is required: standard, keyed different, or keyed alike. Then backset, 2-3/8 or 2-3/4 inches, and strike, the 404 standard or the 408 ANSI. Keyway is optional and defaults to LA. Get the backset and strike right against the existing door and frame prep and the rest is a keying conversation.
8) What is the closest Grade 1 double cylinder deadbolt to the Sargent 484?
The Design Hardware D1 Series double cylinder deadbolt is the nearest straight equivalent: it is a Grade 1 double cylinder deadbolt like the Sargent 484, rated extra heavy duty, and fits a 1-3/4 inch door. The Dexter DB1000 is also a Grade 1 double cylinder deadbolt, covering a 1-3/8 inch to 1-7/8 inch door thickness range. The 484 itself is Grade 1, keyed both sides, non-handed, and orders with a 2-3/8 inch or 2-3/4 inch backset plus a 404 standard or 408 ANSI flat lip strike.
9) Egress code will not allow a key on the inside. What replaces the Sargent 484?
The 484 is keyed on both sides, so where the inside must operate without a key, a cylinder x thumbturn deadbolt is the substitute. In Grade 1 that includes the Falcon D111 with adjustable backset, the Delaney LM Series less-core deadbolt in US26D, the Cal-Royal CRB800 heavy duty single cylinder with a UL 3-hour fire rated latch, and the Deltana CL200LM. The Arrow E60 is a Grade 2 exit deadlock, non-keyed, blank plate outside x thumbturn inside for a 1-3/8 inch to 1-3/4 inch door.
10) Which Grade 1 deadbolts are stated as fire rated where the Sargent 484 is not the choice?
The Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and 6-pin cylinder for a 1-3/8 inch to 1-3/4 inch door, and it carries a fire rating. The Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch. Both are cylinder x thumbturn rather than keyed both sides like the Sargent 484.
11) Do I have to order a left hand or right hand Sargent 484 deadbolt?
No handing to specify. The 484 is non-handed and reversible, so the same part goes on an in-swing or out-swing door, left or right. For a property manager buying a dozen at once, that means one part number covers every opening in the building and there is no wrong-hand return to deal with.
12) Will a 1 inch throw deadbolt reach into my existing frame strike?
The 484 throws a full 1 inch hardened steel bolt. That is the throw commercial specs ask for, and it clears the typical gap at the jamb with enough engagement left in the strike pocket to resist spreading. If you are replacing an older residential bolt with a shorter throw, expect to deepen the strike pocket in the frame, since the bolt needs the full inch of depth behind the strike lip to throw completely.
13) I need key outside and a turn on the inside, not two keys. What's the Sargent equivalent?
The 484 is key both sides only, so it is the wrong function if you want a thumbturn inside. Within the same 480 Series, the single cylinder deadbolt is the cylinder by thumbturn version. Cross-brand Grade 1 options with a thumbturn inside include the Accentra D111, the Falcon D111 classroom deadbolt with adjustable backset, and the Dexter DB1000 single cylinder for 1-3/8 to 1-7/8 inch doors.
14) Is there a lighter-duty double cylinder deadbolt than the Sargent 484?
Yes. The Sargent 484 is Grade 1 heavy duty. Stepping down, the Hager 3214 is a Grade 2 double cylinder deadbolt with a Schlage C keyway for a 1-3/8 inch to 1-3/4 inch door, the Delaney LU Series is a Grade 2 double cylinder deadbolt in stainless steel US32D, and the Callan 210S is a Grade 3 double cylinder deadbolt. The 484 carries the Grade 1 rating and a steel-reinforced case with a 1 inch hardened steel anti-saw bolt.
15) Which of these look like Sargent 484 substitutes but are not deadbolt locks?
Three to rule out. The Arrow 460 is a mortise lock strike with latchbolt and deadbolt cutouts and a straight lip, so it is the frame-side strike, not a lock. The BEST 8T is a T Series tubular deadbolt tube component, a piece of a lock rather than a complete one. The Baldwin Reserve 8BR0618001 is a deadbolt spacer. The Sargent 484 is a complete keyed deadbolt with 6-pin brass cylinders both sides.
16) Which deadbolts take an interchangeable core like the Sargent 484 IC options?
The Sargent 484 orders with a 60 large format interchangeable (FSIC) or 70 small format interchangeable (SFIC) plastic disposable construction core, or LC less cylinder. Among comparable deadbolts, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock prepped for SFIC less core, fitting a 1-3/8 inch to 1-3/4 inch door; the Deltana CL200LAIC is a Grade 2 single deadbolt for interchangeable core supplied less cylinder with a 2-3/4 inch backset; and the Delaney LM Series is a Grade 1 single cylinder less core deadbolt.
17) What is the difference between the Sargent 484 and a classroom function deadbolt?
The Sargent 484 is a double cylinder deadbolt, keyed on both faces so the bolt is thrown and retracted by key from either side. A classroom function deadbolt keys one side and turns from the other: the Falcon D111 is Grade 1 heavy duty classroom function, cylinder x thumbturn, and the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and 6-pin cylinder. The Falcon D211 is the Grade 2 medium duty classroom equivalent.
18) The frame is prepped for a 2-3/4 inch backset. What deadbolts work besides the Sargent 484?
The Sargent 484 is orderable with a 2-3/4 inch backset as well as 2-3/8 inch. If a different brand is needed at that backset, the Deltana CL200LA is a Grade 2 single deadbolt with a 2-3/4 inch backset and the CL200LAIC is the same at 2-3/4 inch prepped for interchangeable core. Several others handle it by adjustment: the Cal-Royal ED500 Grade 3 and the Falcon D111 Grade 1 both list adjustable backset, and the Brinks Raleigh and Mendocino single cylinder deadbolts use a 4 way adjustable backset.
19) What finishes does the Sargent 484 deadbolt come in to match our other hardware?
Twelve finishes: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B dark oxidized satin bronze oil rubbed, 10BE dark oxidized satin bronze, 14 bright nickel, 15 satin nickel, 26 bright chrome, 26D satin chrome, plus BSP black suede powder coat and WSP white suede powder coat. 26D is the one that matches most commercial lever and exit hardware already in the field; the suede powder coats are for storefront and painted-frame work where plated finishes look wrong.
20) Is the Sargent 484 heavy enough for a high-traffic apartment building entrance?
It's built for exactly that. Rated heavy duty and specified for commercial rather than residential service, with a steel-reinforced case and hardened, anti-saw bolt. Multi-tenant residential, schools, healthcare and municipal buildings are the intended applications, and the non-handed body plus twelve finish options make it practical to standardize one part across a whole property.
21) Is an electronic deadbolt an option in place of the Sargent 484?
There are electronic deadbolts in the set, but they trade the 484's mechanical keyed-both-sides operation for credential access. The Codelocks CL2200 is a medium duty electronic surface deadbolt in brushed steel and the CL2210 is an electronic mortise deadbolt. The Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override, and the Nova-D is an RFID multihousing smart electronic deadbolt. The Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote. None of these are keyed cylinder on both faces the way the Grade 1 484 is.
22) What double cylinder deadbolt has decorative trim if the Sargent 484 is too utilitarian for the opening?
For a finished-trim look, the Baldwin Reserve double cylinder deadbolt comes in a contemporary round or contemporary square rose, the Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt in entrance function, and the Emtek 8323 Modern Disc is a brass double cylinder deadbolt. The Sargent 484 covers finish coordination through architectural options including 03 bright brass, 10B oil rubbed dark oxidized satin bronze, 26D satin chrome, and BSP black suede powder coat.
