Sargent 487 26D – Frequently Asked Questions

1) What does classroom function mean on a Sargent 487 deadbolt, and does it lock people in?
Classroom function here means the bolt is thrown and retracted by key from the outside, while the inside stays free for egress. Nobody gets locked in. That is what makes it usable on a classroom or an office where the code requires people to get out without a key, and it is why it is a single cylinder unit rather than a double cylinder deadbolt like the Callan 210S.
2) Do I have to order the Sargent 487 deadbolt handed for a left or right swing door?
No handing to specify. The 487 is non-handed and reversible, so the same part goes on a left-hand or right-hand swing. For a property manager buying several at once, that means one part number covers every door in the building regardless of swing.
3) Which backset do I need for the Sargent 487 deadbolt, 2-3/8 or 2-3/4?
Both are offered. Measure from the door edge to the center of the existing bolt hole: 2-3/8 inches is the standard on the 487 and 2-3/4 inches is the other choice. On commercial metal doors already prepped for a lockset you will usually be at 2-3/4 inches. Get this wrong and the cross bore will not line up with the bolt hole in the edge of the door.
4) Will the Sargent 487 deadbolt latch into the strike prep I already have in the frame?
You pick the strike with the order. The 404 is the 2-3/4 inch standard strike, which drops into a frame cut for a common deadbolt strike. The 408 is the ANSI 4-7/8 inch flat lip strike, which is what hollow metal frames on commercial jobs are typically prepped for. The bolt itself throws 1 inch of hardened steel, so it reaches well into either strike box.
5) Can I get the Sargent 487 deadbolt keyed alike to the other locks in my building?
Yes. Keying is a required selection: standard keying, KD keyed different, or KA keyed alike so one key runs a group of doors. Keyway choice runs across 40 Sargent keyways with LA as the standard, including the C, H, L and R families plus R, S and U, so the deadbolt can be cut into an existing Sargent system rather than carrying its own key.
6) Can I order the Sargent 487 deadbolt without a cylinder so my locksmith can core it later?
Yes, and there are three ways to do it. LC ships less cylinder entirely. The 60 option is prepped for Sargent large format interchangeable core with a plastic disposable construction core, and the 70 option is prepped for small format interchangeable core, also with a disposable construction core. Those construction core options let the trades key the job during the build and swap to permanent cores at turnover. The fourth choice is the conventional 6 pin standard cylinder if you do not run interchangeable core.
7) Is the Sargent 487 a Grade 1 deadbolt, and what does that mean for a school corridor?
ANSI/BHMA Grade 1, the top commercial performance tier, and rated heavy duty for commercial use. On a school or institutional opening that means the highest strength and cycle performance level the standard defines, which is what a spec for educational or government work usually calls for. Grade 2 deadbolts like the Arrow DBX61 or the Falcon D211 sit a tier below.
8) Which classroom deadbolt should I use on a 1-3/8 inch door?
The Sargent 487 is built for 1-3/4 inch to 2 inch doors, so a thinner leaf calls for a different part. The Hager 3118 is a Grade 1 classroom deadbolt with a 6-pin cylinder in the Schlage C keyway and a door thickness range of 1-3/8 inch to 1-3/4 inch. If Grade 2 is acceptable for the opening, the Falcon D211 is a Grade 2 classroom function deadbolt with single cylinder operation at a medium duty level.
9) What is the closest Grade 1 classroom function deadbolt to the Sargent 487 from another manufacturer?
The Falcon D111 is the nearest match. It is a Grade 1 classroom deadbolt in cylinder x thumbturn function at a heavy duty level, the same grade, function and duty class the Sargent 487 carries. The Falcon uses an adjustable backset, while the Sargent 487 is ordered with a fixed 2-3/8 inch or 2-3/4 inch backset. The Hager 3118 is also a Grade 1 classroom deadbolt in cylinder x thumbturn function, supplied in the Schlage C keyway with a 6-pin cylinder and a 1-3/8 inch to 1-3/4 inch door thickness range, so it suits a thinner door than the Sargent 487, which covers 1-3/4 inch to 2 inch.
10) I need a Grade 1 deadbolt keyed on both sides instead of a thumbturn. What replaces the Sargent 487?
The Sargent 487 is a single cylinder deadbolt, key outside and thumbturn inside. For a double cylinder opening, the Design Hardware D1 Series is a Grade 1 double cylinder deadbolt at an extra heavy duty level for 1-3/4 inch doors, and the Dexter DB1000 is a Grade 1 double cylinder deadbolt covering 1-3/8 inch to 1-7/8 inch door thickness. Both are keyed on both faces, so neither provides the free inside egress the classroom function on the Sargent 487 gives.
11) Can I use a Corbin Russwin DL2211 in place of a Sargent 487?
The DL2211 is a Grade 1 cylindrical deadlock in classroom function for 1-3/4 inch doors, so it matches the Sargent 487 on grade and on classroom function. The difference is the inside trim: the DL2211 is cylinder x blank, meaning there is no thumbturn on the inside face, while the Sargent 487 is cylinder x thumbturn and can be thrown or retracted by hand from inside. If the room needs the occupant to operate the bolt without a key, the two are not equivalent.
12) What Grade 1 deadbolt works on a door thicker than 2 inches?
The Sargent 487 is rated for 1-3/4 inch to 2 inch doors. Above that, the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock covering 1-3/4 inch to 2-1/4 inch door thickness. Note that the DL3011 is a cylinder x blank device, so the inside face has no thumbturn, unlike the cylinder x thumbturn arrangement on the Sargent 487.
13) What Grade 1 deadbolt can I order less core for an existing interchangeable core system?
The Sargent 487 can be ordered LC less cylinder, or with a Sargent large format (FSIC) or small format (SFIC) disposable construction core. Among other Grade 1 options, the Delaney LM Series is a Grade 1 single cylinder less core deadbolt in cylinder x thumbturn function, supplied in dull chrome US26D. For a Grade 2 requirement, the Deltana CL200LAIC is a single cylinder interchangeable core deadbolt supplied without a cylinder, with a 2-3/4 inch backset, and 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.
14) Should I use a deadbolt like the Sargent 487 or a cylindrical deadlock on a classroom door?
A deadbolt with a thumbturn inside, like the 487, gives the person in the room the ability to throw the bolt by hand, which is what most classroom lockdown procedures now want. A cylinder by blank deadlock such as the Corbin Russwin DL2211, also Grade 1 classroom function for 1-3/4 inch doors, has no inside turn at all and is keyed from one side only. Choose the blank plate version when you specifically do not want occupants throwing the bolt.
15) Is a Grade 3 residential deadbolt an acceptable substitute for the Sargent 487 on a school door?
No. Deadbolts like the Cal-Royal ED500 and the Cal-Royal LSD are Grade 3 and built for 1-3/8 to 1-3/4 inch doors, and the Bravura 310B Elite and Cal-Royal CB160 are Grade 2. None of them meet a Grade 1 spec. If the drawing calls Grade 1, the substitutes that actually hold are the Falcon D111 or the Design Hardware D1 Series, both Grade 1, though the D1 is a double cylinder unit with no inside turn.
16) Is the Accentra D111 the same as the Sargent 487?
They are not interchangeable despite both being Grade 1 single cylinder deadbolts in cylinder x thumbturn function. The Accentra D111 is a D Series deadbolt with a 2-3/8 inch backset and a door thickness range of 1-3/8 inch to 1-3/4 inch. The Sargent 487 covers 1-3/4 inch to 2 inch doors and is ordered in either a 2-3/8 inch or 2-3/4 inch backset, so on a 2 inch door or a 2-3/4 inch bore the Accentra will not drop in.
17) What is a lighter duty alternative to the Sargent 487 for a low traffic interior door?
For an opening that does not need Grade 1, the Falcon D211 is a Grade 2 classroom function deadbolt with single cylinder operation at a medium duty level. The Arrow DBX61 is a Grade 2 single cylinder deadbolt in cylinder x thumbturn function, and the Cal-Royal CB160 is a Grade 2 single cylinder deadbolt with a tamper-resistant cylinder guard. All three keep the key outside and thumbturn inside arrangement the Sargent 487 uses, which is a cylinder x thumbturn single cylinder function.
18) Is the Arrow E60 exit deadlock a substitute for a Sargent 487 classroom deadbolt?
No. The Arrow E60 is a Grade 2 non-keyed exit deadlock in blank plate x thumbturn function for 1-3/8 inch to 1-3/4 inch doors. It has no cylinder, so there is no key control from the outside at all. The Sargent 487 is keyed with a single cylinder outside and a thumbturn inside. If the specification calls for a key to lock and unlock the room from the corridor, the E60 does not meet it.
19) What finishes does the Sargent 487 deadbolt come in to match existing hardware?
Twelve finishes cover most existing building standards: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B oil rubbed dark oxidized satin bronze, 10BE dark oxidized satin bronze, 14 bright nickel, 15 satin nickel, 26 bright chrome, 26D satin chrome, plus BSP black suede and WSP white suede powder coats. 26D satin chrome is the usual pick on institutional and school work where the rest of the hardware is already satin chrome.
20) How well does the Sargent 487 deadbolt resist someone attacking the bolt?
The bolt is hardened steel with an anti-saw design and a full 1 inch throw, carried in a reinforced steel case with a 6-pin brass cylinder. The anti-saw construction is aimed at someone trying to cut the bolt through the gap between door and frame, and the 1 inch throw keeps the bolt deep enough in the strike that spreading the frame is harder.
21) What is the difference between the Sargent 487 and an electronic deadbolt like the Codelocks CL2210?
The Sargent 487 is a mechanical keyed deadbolt, single cylinder with a thumbturn inside, and depends on a key system for access control. The Codelocks CL2210 is an electronic mortise deadbolt, and the CL2200 is an electronic surface deadbolt at a medium duty level in brushed steel. The Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override. Those change the credential from a cut key to a code or card, which is a different keying and maintenance program from the Sargent keyway families the 487 is ordered in.
22) I need a deadbolt in oil rubbed bronze for a commercial door. How does the Sargent 487 compare on finish?
The Sargent 487 is offered in 10B dark oxidized satin bronze oil rubbed, along with 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10BE dark oxidized satin bronze, 14 bright nickel, 15 satin nickel, 26 bright chrome, 26D satin chrome, and black and white suede powder coat. Among peers, the Delaney LM Series Grade 1 deadbolt is supplied in dull chrome US26D and the Delaney LU Series Grade 2 double cylinder in stainless steel US32D, so those are single finish orders where the Sargent 487 gives a bronze option to match existing trim.
