Sargent 464-26D – Frequently Asked Questions

1) Will the Sargent 464 deadbolt fit a 1-3/8 inch door?
Yes. The Sargent 464 double cylinder deadbolt covers door thickness from 1-3/8 inches up to 2 inches, so it handles thinner older wood doors as well as standard 1-3/4 inch commercial doors and the thicker 2 inch openings. That upper limit is wider than a lot of Grade 2 deadbolts, which stop at 1-3/4.
2) What backset do I order for a Sargent 464 deadbolt, 2-3/8 or 2-3/4?
Both are orderable on the 464. Measure from the door edge to the center of the existing bore: 2-3/8 inches is the standard configuration, 2-3/4 inches is the optional one. Those are the two backsets used on virtually all bored door prep, so an existing prepped door will match one of them. Getting it wrong means the bolt will not line up with the strike, so measure before you pick the option.
3) Is a double cylinder deadbolt the right choice, or should I use a cylinder and thumbturn?
A double cylinder deadbolt like the Sargent 464 takes a key on both sides, inside and out. Use it where you do not want someone reaching through glass or a sidelite to turn a thumbturn, or where you need to control who leaves as well as who enters. The tradeoff is egress: no one gets out without a key, which many occupancy codes will not allow on a required exit door. If the opening needs free egress, order a cylinder x thumbturn instead. Comparable options ZenSupply carries include the Dexter DB2000 Grade 2 single cylinder for 1-3/8 to 1-3/4 inch doors, or the Arrow DBX61 Grade 2 cylinder x thumbturn.
4) Which strike do I need with the Sargent 464 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 what a hollow metal frame with ANSI prep already has routed into it. If the frame is prepped for ANSI, order the 408 or you will be filling and re-routing.
5) Can I get Sargent 464 deadbolts keyed alike across a building, and on my existing keyway?
Yes on both counts. Keying is specified at order: standard keying, KD keyed different, or KA keyed alike so one key runs a whole set of doors. The keyway is a separate selection, with LA as the standard and 40 keyways available in total across the 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 families. Pick the keyway your building already runs and the 6-pin brass cylinder drops into your existing Sargent masterkey system.
6) Is a 1 inch throw deadbolt enough for a commercial exterior door?
The 464 throws a full 1 inch of hardened steel, which is the length that reaches past the gap and well into the frame so the door cannot be pried or jimmied clear of the bolt, and the hardened core resists sawing. Paired with Grade 2 medium-duty certification, it is sized for commercial, multi-family and light commercial entries rather than high-abuse or high-cycle openings. For a heavier exterior opening, ZenSupply also carries Grade 1 double cylinder deadbolts such as the Design Hardware D1 Series, rated extra heavy duty for 1-3/4 inch doors.
7) Can I put the Sargent 464 double cylinder deadbolt on a fire rated door?
Fire rating is a question to settle on the specific opening before you order the 464, and a keyed-both-sides deadbolt on a rated egress door is usually the wrong call regardless, because it locks people in. Where the opening does need a fire rated deadbolt, ZenSupply carries the Hager 3215 single cylinder deadbolt with a 1 inch throw, listed as fire rated for 1-3/8 to 1-3/4 inch doors, and the Hager 3214 Grade 2 double cylinder, also fire rated for that same thickness range.
8) What is the closest Grade 2 double cylinder deadbolt to the Sargent 464 from another manufacturer?
The Dexter DB2000 series double cylinder deadbolt is the nearest peer: Grade 2, double cylinder function, for doors 1-3/8 to 1-3/4 inch. The Sargent 464 is also Grade 2 double cylinder and covers a wider door range, 1-3/8 to 2 inch, so on a door thicker than 1-3/4 inch the 464 is the one that still fits. The Delaney LU series double cylinder deadbolt is a second Grade 2 double cylinder option, offered in stainless steel US32D finish.
9) I need a keyed deadbolt but egress code says no key on the inside - what replaces the Sargent 464?
The Sargent 464 is keyed on both sides, so a room that must allow key-free exit needs a cylinder by thumbturn deadbolt instead. The Falcon D211 is Grade 2 medium duty with cylinder by thumbturn operation, and the Dexter DB2000 single cylinder is Grade 2 cylinder by thumbturn for doors 1-3/8 to 1-3/4 inch. For a door that needs no key at all on either side, the Arrow E60 is a Grade 2 exit deadlock, blank plate by thumbturn, for doors 1-3/8 to 1-3/4 inch.
10) What double cylinder deadbolt steps up from Grade 2 to Grade 1 for a high abuse entrance?
For a heavier opening, the Design Hardware D1 series double cylinder deadbolt is Grade 1 extra heavy duty for 1-3/4 inch doors, and the Dexter DB1000 double cylinder is Grade 1 for doors 1-3/8 to 1-7/8 inch. The Sargent 464 is Grade 2 medium duty and spans 1-3/8 to 2 inch doors, so the D1 is fixed to a single door thickness where the 464 is adjustable across the range.
11) My door is a 1-3/4 inch fire rated opening - does the Sargent 464 or a Hager deadbolt suit it better?
The Hager 3214 Grade 2 double cylinder deadbolt carries a fire rating and fits doors 1-3/8 to 1-3/4 inch, with a Schlage C keyway. The Sargent 464 is a Grade 2 double cylinder for doors 1-3/8 to 2 inch and takes Sargent keyways, LA standard with a large range of C, H, L and R sections available, so the deciding factor is usually which keying system the building is already on.
12) What looks like a substitute for the Sargent 464 but will not work as one?
Three that get mistaken for it: the Arrow 460 shares the 460 number but is a mortise lock strike, not a deadbolt. The Baldwin Reserve 8BR0618001 is described as double cylinder but is a deadbolt spacer, a component rather than a lock. And the Corbin Russwin DL3011 and DL3211 are Grade 1 cylindrical deadlocks with cylinder by blank trim, meaning no key and no turn on the inside face, which is not the two-sided key control the Sargent 464 provides.
13) Do I have to worry about handing when ordering the Sargent 464 deadbolt?
No. The 464 is non-handed and reversible, so the same part goes on a left-hand or right-hand swing door. For a property manager buying several at once, that means one part number covers every opening in the building regardless of which way the doors swing.
14) What finishes does the Sargent 464 deadbolt come in, and will it match my other door hardware?
Eight finishes are offered on the 464: 03 bright brass clear coated, 04 satin brass clear coated, 10 satin bronze clear coated, 10B dark oxidized satin bronze oil rubbed, 10BE dark oxidized satin bronze, 26 bright chromium plated over nickel, 26D satin chromium plated over nickel, and BSP black suede powder coat. All eight are available with either backset and either strike, so finish never restricts your other choices. 26D is the usual match for commercial levers and closers already on most buildings.
15) Can I use the Sargent 464 to replace a Grade 3 residential double cylinder deadbolt?
In most cases yes, provided the bore matches. The 464 uses standard bored door prep at 2-3/8 or 2-3/4 inch backset and covers 1-3/8 to 2 inch doors, which is a wider thickness range than typical Grade 3 double cylinder units. Stepping from a Grade 3 like the Callan 210S up to the Grade 2 464 buys you medium-duty commercial cycle performance on doors that are seeing more traffic than the original hardware was picked for.
16) Does the Sargent 464 deadbolt use a rekeyable cylinder or an interchangeable core?
The 464 is built with a 6-pin brass cylinder keyed both sides, rekeyable by pinning and compatible with Sargent masterkey systems. It is not a small format interchangeable core product, so if your facility standardizes on SFIC and swaps cores rather than repinning, look at an SFIC deadlock instead, such as the Arrow E61 in 26D prepped for SFIC less core, which fits 1-3/8 to 1-3/4 inch doors.
17) Is the Sargent 464 a mortise deadbolt or does it drop into a standard bored door?
It is a bored deadbolt, installed with standard door prep at either 2-3/8 or 2-3/4 inch backset plus a strike cut in the frame, not a mortise pocket. The case is a reinforced standard duty design with a Cycolac rust-proof cement case. If your doors are actually prepped for a mortise deadbolt pocket, the 464 will not fill it, and you would want a mortise unit such as the Dormakaba D900 small case mortise deadbolt instead.
18) Is there a lighter duty double cylinder deadbolt than the Sargent 464 for a low traffic door?
Two Grade 3 double cylinder options exist: the Callan 210S and the Deltana 7312KA2, which covers doors 1-3/8 to 2 inch, the same thickness span as the Sargent 464. The 464 is Grade 2 with a 1 inch hardened steel throw and a 6-pin brass cylinder that works in Sargent masterkey systems, which is what carries it into medium traffic commercial use.
19) We standardize on small format interchangeable core - what replaces the Sargent 464 there?
The Sargent 464 uses a 6-pin brass cylinder keyed both sides on Sargent keyways. If the facility keys on SFIC, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock with SFIC prep less core for doors 1-3/8 to 1-3/4 inch, and the Deltana CL200LAIC is a Grade 2 interchangeable core single deadbolt with a 2-3/4 inch backset. Both are single cylinder, so an SFIC opening that must be keyed on both faces is a different conversation than a straight swap.
20) My opening needs a 2-3/4 inch backset only - what are my options besides the Sargent 464?
The Sargent 464 is ordered with either a 2-3/8 inch or a 2-3/4 inch backset, so it covers that opening directly. If a fixed 2-3/4 inch single cylinder is wanted instead, the Deltana CL200LA is a Grade 2 cylinder by thumbturn deadbolt built at 2-3/4 inch backset. For openings where the backset is uncertain, the Cal-Royal ED500 is a Grade 3 single cylinder with adjustable backset for 1-3/8 to 1-3/4 inch doors.
21) Is an electronic deadbolt an alternative to the Sargent 464 for a multi-family building?
The Sargent 464 is a mechanical Grade 2 double cylinder deadbolt keyed on both faces. Where credentials replace keys, the Delaney KP400 is a Grade 2 electronic deadbolt with programmable remote, the Dormakaba Nova-D is an RFID multihousing smart electronic deadbolt, and the Codelocks CL2200 is a medium duty electronic surface deadbolt in brushed steel. Those change how the door is credentialed and managed rather than dropping into the same key system the 464 shares with other Sargent hardware.
22) What is the difference between the Sargent 464 and a classroom function deadbolt like the Falcon D111?
The Falcon D111 is a Grade 1 heavy duty classroom deadbolt with cylinder by thumbturn operation, and the Hager 3118 is a Grade 1 classroom deadbolt with Schlage C keyway and 6-pin cylinder for doors 1-3/8 to 1-3/4 inch. Classroom function keeps a turn on the room side so an occupant can throw and retract the bolt without a key. The Sargent 464 requires a key from both the interior and exterior side, which is the point of the double cylinder configuration.
