Corbin Russwin DL3212-KEYED Cylindrical Deadlock Double Cylinder with 1" Steel Deadbolt

Commercial-Grade Double Cylinder Cylindrical Deadlock for Demanding Security Applications

The Corbin Russwin DL3212-KEYED is a heavy-duty cylindrical deadlock from the DL3200 Series, engineered for commercial applications requiring key-operated access from both sides of the door. Designed for standard 1-3/4" (44mm) door thickness with a standard 2-3/4" (70mm) backset (optional 2-3/8" / 60mm available), this double cylinder deadlock features a 1" throw solid steel deadbolt with a hardened, free spinning steel pin insert for superior forced-entry resistance. The non-handed design simplifies installation across a wide range of door configurations, and the ANSI/BHMA E0140 Series rating confirms compliance with commercial security standards.

Corbin Russwin DL3212 626 – Frequently Asked Questions

1) Will the Corbin Russwin DL3212 deadlock fit a 1-3/4 inch commercial door?
Yes, 1-3/4 inch is the door thickness the DL3212 is built for, with a 2-3/4 inch backset as standard. A 2-3/8 inch backset is available as an option if your doors are already bored that way. It is non-handed, so the same lock works on left or right hand openings without any field conversion.
2) Does the DL3212 have a thumbturn on the inside, or is it key on both sides?
Key both sides. The DL3212 is a double cylinder deadlock, meaning it is operated by key from either face of the door and there is no thumbturn. That restricts keyless egress, so check your local egress code before putting it on an exit door. If you need a thumbturn inside, you want a single cylinder deadbolt instead, such as the Falcon D111 Grade 1 or the Dexter DB1000 cylinder x thumbturn.
3) Will the DL3212 deadbolt reach my existing strike and frame?
The deadbolt throws 1 inch, solid steel with a hardened free spinning steel pin insert to resist cutting. A 2-3/4 by 1-1/8 inch strike ships with the lock, and optional strikes and wrought boxes are available for unusual frame conditions. With a 1 inch throw you need the frame pocket drilled deep enough to take the full bolt, so a wrought box behind the strike is worth specifying on hollow metal.
4) Can I get the DL3212 to take my existing interchangeable core?
Yes. Besides the standard conventional 6-pin cylinder in the L4 keyway, the DL3212 can be ordered CL6 less core for a Corbin Russwin large format interchangeable core 6-pin, or CL7 less core for a 7-pin IC. Both ship without the core so you drop in the core already on your master key system. The conventional cylinder option comes 0-bitted with two nickel silver keys.
5) Which double cylinder deadbolt should I use on a door thinner than 1-3/4 inches?
The Corbin Russwin DL3212 is specified for 1-3/4 inch doors. For thinner doors, the Dexter DB1000 double cylinder deadbolt is Grade 1 and covers 1-3/8 inch to 1-7/8 inch, and the Dexter DB2000 double cylinder is Grade 2 covering 1-3/8 inch to 1-3/4 inch. The Deltana 7312KA2 double cylinder is Grade 3 and spans 1-3/8 inch to 2 inches.
6) What is the closest Grade 1 double cylinder deadbolt to the Corbin Russwin DL3212 from another brand?
The Design Hardware D1 Series double cylinder deadbolt is the nearest match. Like the DL3212, it is a Grade 1 double cylinder deadbolt for 1-3/4 inch doors, and it is rated extra heavy duty. The DL3212 is keyed on both sides with a conventional 6-pin L4 keyway cylinder as standard, and also comes in CL6 less-core LFIC 6-pin and CL7 7-pin IC less-core versions for facilities running an interchangeable core system.
7) I need a thumbturn on the inside instead of a second key - what replaces the DL3212?
The DL3212 is key-operated from either side, with no thumbturn. For a cylinder by thumbturn deadbolt at the same Grade 1 level, look at the Falcon D111, the Accentra D111 with a 2-3/8 inch backset, the Delaney LM Series less-core, the Deltana CL200LM, or the Dexter DB1000 single cylinder, which covers 1-3/8 inch to 1-7/8 inch doors.
8) My AHJ will not allow double keyed deadbolts on an egress door - what do I use instead?
The Corbin Russwin DL3212 requires a key from either side, which restricts keyless egress. Where free egress must be maintained, the Arrow E60 exit deadlock is non-keyed with a blank plate on the outside and a thumbturn inside for 1-3/8 inch to 1-3/4 inch doors, so the door can always be unlocked from the secure side without a key.
9) What finishes does the DL3212 come in for matching existing hardware in a building?
Seven finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil-rubbed satin bronze, 625 bright chrome, 626 satin chrome, and BSP black suede powder coat. Every one of those is available with any of the three cylinder choices, so you can standardize finish across a property and still vary the keying setup door to door. 626 is the usual match for commercial lever and exit hardware.
10) Can the DL3212 be put on a master key system?
Yes. The DL3200 Series supports master keying, construction master keying, security keying, visual key control and concealed key control. The standard cylinder is a brass 6-pin in the L4 keyway; security cylinders are available through Quick Codes if you need tighter key control. For facilities already running Corbin Russwin large format IC, order the CL6 less core version and key it into your existing system.
11) Should I use a cylindrical deadlock like the DL3212 or a mortise deadbolt?
The DL3212 is a bored cylindrical deadlock, so it installs in a standard cross bore at a 2-3/4 inch backset and is far quicker to prep or retrofit than cutting a mortise pocket. Mortise deadbolts, like the Dormakaba D900 small case mortise deadbolt, suit narrow stiles and doors already mortise prepped. If your opening is an aluminum storefront, neither applies, you would look at a hook bolt deadlock such as the International Door Closers DH-1821.
12) What is a comparable double cylinder deadbolt if I do not need Corbin Russwin keying?
On the same Grade 1 tier, the Design Hardware D1 Series double cylinder deadbolt is rated extra heavy duty and also listed for 1-3/4 inch doors, and the Dexter DB1000 double cylinder covers 1-3/8 to 1-7/8 inch doors if your thicknesses vary. Step down a grade and there is the Hager 3214 double cylinder, Grade 2 in the Schlage C keyway, which matters if the building is already on C keyway. The DL3212 is the one to keep if you need the L4 keyway or Corbin Russwin interchangeable cores.
13) Is there a lighter duty double cylinder deadbolt if Grade 1 is more than the opening needs?
Yes. The Delaney LU Series double cylinder deadbolt is Grade 2 in a stainless steel US32D finish, the Hager 3214 double cylinder is a Grade 2 lock with a Schlage C keyway for 1-3/8 inch to 1-3/4 inch doors, and the Callan Model 210S double cylinder is Grade 3. The Corbin Russwin DL3212 carries an ANSI/BHMA E0140 Series rating and ships with a conventional 6-pin L4 keyway cylinder.
14) We run SFIC cores site-wide - what single cylinder deadlock pairs with the DL3212 openings?
The DL3212 handles interchangeable core in its CL6 less-core LFIC 6-pin and CL7 IC 7-pin less-core builds, both of which are Corbin Russwin format. For a single cylinder deadlock prepped for a small format core instead, the Arrow E61 is a Grade 2 single cylinder deadlock with SFIC prep less core for 1-3/8 inch to 1-3/4 inch doors. The Deltana CL200LAIC is a Grade 2 single cylinder interchangeable core deadbolt with a 2-3/4 inch backset, which matches the DL3212 standard backset.
15) What is the difference between the DL3212 and a mortise deadbolt like the Dormakaba D900?
The DL3212 is a cylindrical deadlock, bored into the door face for a 2-3/4 inch backset with a 2-3/4 inch by 1-1/8 inch strike. The Dormakaba D900 is a small case mortise deadbolt in a cylinder by thumbturn function, supplied keyed different with SC keyways, and requires a mortise pocket in the door edge rather than a bored prep. The two are not drop-in swaps for each other.
16) Is there a fire rated alternative to the Corbin Russwin DL3212 deadbolt?
For openings where a fire rating has to be documented, the Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch, and the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and 6-pin cylinder carrying a fire rating for 1-3/8 inch to 1-3/4 inch doors. Both are cylinder by thumbturn rather than keyed on both sides like the DL3212.
17) What comes in the box with the DL3212 deadlock?
The lock ships with the 2-3/4 by 1-1/8 inch strike, a standard front measuring 2-1/4 by 1-1/8 inches in wrought brass or bronze, and two nickel silver keys on the conventional cylinder version. Order the CL6 or CL7 less core version and no core or keys are included, you supply those from your own system.
18) Can I use an electronic deadbolt in place of the DL3212 for keyless access?
If you want to drop mechanical keys entirely, the Codelocks CL2200 is a medium duty electronic surface deadbolt and the CL2210 is an electronic mortise deadbolt, while the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override. The DL3212 is a mechanical keyed lock with a conventional 6-pin L4 keyway cylinder and supports master keying, construction master keying, and key control programs instead.
19) Does the Arrow 460 strike work with the Corbin Russwin DL3212?
No. The Arrow 460 is a mortise lock strike for latchbolt by deadbolt functions with a straight lip, cut for a mortise case. The DL3212 is a cylindrical deadlock and comes with its own 2-3/4 inch by 1-1/8 inch strike, with optional strikes and wrought boxes available for other frame conditions.
