Corbin Russwin DL3012 626 – Frequently Asked Questions

1) Is a double cylinder deadbolt like the DL3012 legal on an exit door?
The DL3012 is key operated from both sides, with no thumbturn on the inside. That means anyone leaving has to have a key in hand, which rules it out on most required means-of-egress doors. It belongs on openings where keyed control from both faces is what you want: a stockroom, a rear service door, a glass door where a thumbturn could be reached through the glass. If the door is an exit and you need free egress, order a single cylinder with a thumbturn instead, such as the Falcon D111 Grade 1 or the Delaney LM Series Grade 1 cylinder x thumbturn.
2) Will the DL3012 deadbolt latch into the strike pocket I already have?
The bolt throws 1 inch and measures 5/8 inch wide by 3/4 inch high, and the lock ships with a 2-3/4 by 1-1/8 inch strike. If your existing frame strike is that size and the pocket behind it is deep enough for a full 1 inch throw, you can reuse it. On a hollow metal frame with a shallow dimple rather than a real pocket, plan to cut the frame or use the supplied strike, otherwise the bolt bottoms out and never fully extends.
3) What is the difference between the standard cylinder, CL6, and LC options on the Corbin Russwin DL3012?
Three ways to buy it. Standard gets you a conventional brass 6-pin cylinder in the L4 keyway, 0-bitted, with two keys, so it arrives ready to key up. CL6 is prepped for a Corbin Russwin large format interchangeable core, 6-pin, shipped less core, which is what you order when the building already runs an LFIC system and your locksmith drops in cores from stock. LC is less conventional cylinder entirely, for when you're supplying your own mortise cylinders to match an existing keyway. All three are offered in every finish.
4) Is the Corbin Russwin DL3012 a mortise lock or does it go in a bored hole?
Bored. The DL3012 is a cylindrical deadlock, so it installs through a cross bore in the door face with an edge bore for the bolt, the same prep family as a cylindrical lockset. It is not a mortise deadlock and will not drop into a mortise pocket. If the door already has a mortise case cut into the edge, look at a mortise deadbolt such as the Dormakaba D900 small case mortise deadbolt instead of trying to fill and re-prep the door.
5) What is the closest Grade 1 double cylinder deadbolt equivalent to the Corbin Russwin DL3012?
The Design Hardware D1 Series is the nearest peer: it is a Grade 1 double cylinder deadbolt rated extra heavy duty, for 1-3/4 inch doors. The DL3012 is a cylindrical deadlock keyed from either side, built to ANSI/BHMA E0140 Series, and it covers a wider door thickness range of 1-3/4 inch to 2-1/4 inch. If the opening is a standard 1-3/4 inch commercial door, both suit; if the door is thicker than 1-3/4 inch, the DL3012 range is what covers it.
6) What double cylinder deadbolt works on a 1-3/8 inch door instead of the DL3012?
The DL3012 starts at 1-3/4 inch and runs to 2-1/4 inch, so a thinner door needs a different bolt. The Dexter DB1000 Series double cylinder deadbolt is Grade 1 and fits 1-3/8 inch to 1-7/8 inch doors; the Dexter DB2000 Series double cylinder is Grade 2 for 1-3/8 inch to 1-3/4 inch; the Hager 3214 double cylinder deadbolt is Grade 2 with a Schlage C keyway and covers 1-3/8 inch to 1-3/4 inch.
7) Which deadbolt should be used when the inside of the door needs a thumbturn rather than a second key?
The DL3012 is keyed from either side, so there is no inside thumbturn on it. For cylinder by thumbturn commercial openings, the Falcon D111 is a Grade 1 heavy duty deadbolt with an adjustable backset, the Delaney LM Series is a Grade 1 less core deadbolt in dull chrome US26D, the Deltana CL200LM is a Grade 1 single cylinder deadbolt, and the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and 6-pin cylinder. Egress codes in many occupancies drive this choice, so confirm which side the authority having jurisdiction allows a key on.
8) Which of the comparable deadbolts carry a fire rating the DL3012 pairs with?
For openings where the bolt itself has to carry a fire rating, the Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch, and the Hager 3115, 3118, 3214 and 3215 are listed as fire rated. The Corbin Russwin DL3012 is rated to ANSI/BHMA E0140 Series. Note that the Cal-Royal and Hager options above are cylinder by thumbturn rather than keyed both sides.
9) What is the difference between the DL3012 and the Accentra D111 for a commercial opening?
The Accentra D111 is a Grade 1 single cylinder deadbolt from the D Series, cylinder by thumbturn, with a 2-3/8 inch backset and a 1-3/8 inch to 1-3/4 inch door thickness range. The Corbin Russwin DL3012 is keyed on both faces, uses a 2-3/4 inch backset standard with 2-3/8 inch optional, and covers 1-3/4 inch to 2-1/4 inch doors. The deciding factors are whether the inside face takes a key or a turn and what backset the existing bore already uses.
10) Which single cylinder deadbolts accept an interchangeable core the way the DL3012 does?
The DL3012 offers a CL6 less core LFIC 6-pin option for Corbin Russwin cores, alongside the standard conventional 6-pin L4 keyway cylinder. Among comparable single cylinder deadbolts, the Deltana CL200LAIC is a Grade 2 interchangeable core deadbolt supplied non cylinder with a 2-3/4 inch backset, the Delaney LM Series is a Grade 1 less core deadbolt, and the Arrow E61 26D IC is prepped for SFIC less core.
11) Do I have to specify a hand when ordering the Corbin Russwin DL3012?
No handing to call out. The DL3012 is non-handed, so one part number works on left hand and right hand doors alike. For a property manager standardizing across a building, that's one less line on the order and one less way to get the wrong box.
12) Can the Corbin Russwin DL3012 be master keyed into an existing building system?
Yes. The DL3012 supports master keying and construction master keying, plus 7-pin conventional, interchangeable core, security and security IC cylinders, visual key control, concealed key control, and Pyramid in both conventional and IC. If the facility is already on a Corbin Russwin system, order the CL6 version less core and key it to what you run. Bear in mind that as a double cylinder it takes two cylinders, so the keying order covers both faces of the door.
13) Will the Corbin Russwin DL3012 mount on a door with a beveled edge?
It handles both. The front plate is wrought brass or bronze at 2-1/4 by 1-1/8 inches and suits a flat door or one beveled 1/8 inch in 2 inches, which is the standard bevel on a commercial door edge. No separate beveled front to specify.
14) What else could I use instead of the Corbin Russwin DL3012 double cylinder deadlock?
Depends on why you're looking elsewhere. Straight equivalent in a keyed-both-sides Grade 1: the Design Hardware D1 Series double cylinder, listed for 1-3/4 inch doors, extra heavy duty. Lighter and cheaper duty for a lower-traffic opening: the Delaney LU Series Grade 2 double cylinder or the Hager 3214 Grade 2. Wrong direction if you need egress: any of those is still keyed both sides. And watch the Baldwin 8BR0618001, which reads as a deadbolt in a search but is a spacer, not a lock.
15) Does the Arrow E60 exit deadlock do the same job as a DL3012?
No. The Arrow E60 is a Grade 2 non-keyed exit deadlock with a blank plate on one side and a thumbturn on the other, for 1-3/8 inch to 1-3/4 inch doors, so the outside face has no key access at all. The DL3012 is keyed from either side. The E60 suits an exit-only door that is thrown from inside; it will not give a keyholder entry from the outside.
16) Can a Baldwin or Emtek double cylinder deadbolt replace a Corbin Russwin DL3012 on a commercial door?
They are double cylinder, but they are decorative residential trim rather than commercial deadlocks. The Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt, the Baldwin Reserve line offers contemporary round and square double cylinder deadbolts, and the Emtek 8323 Modern Disc is a brass double cylinder deadbolt. The DL3012 is a commercial cylindrical deadlock built to ANSI/BHMA E0140 Series with keying support that includes master keying and interchangeable core. On a keyed-both-sides commercial opening that has to key into a facility master system, the DL3012 is the one built for it.
17) What looks like a DL3012 substitute in a deadbolt search but is actually a different part?
Several. The Baldwin Reserve 8BR0618001 is a deadbolt spacer, not a lock. The BEST 8T is a T Series tubular deadbolt tube component. The Arrow 460 is a mortise lock strike with a straight lip for latchbolt and deadbolt functions. The International Door Closers DL-4511 and DT-1851 are deadlatch locks, which latch on closing rather than throwing a keyed deadbolt. The DL3012 is the complete cylindrical deadlock itself, keyed both sides, with a 2-3/4 inch by 1-1/8 inch standard strike.
18) Is there an electronic or keypad alternative to a keyed-both-sides deadbolt like the DL3012?
Yes, if credentials rather than cut keys are wanted. The Codelocks CL2200 is a medium duty electronic surface deadbolt in brushed steel, the Codelocks CL2210 is an electronic mortise deadbolt, the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override, the Dormakaba Nova-D is an RFID multihousing smart electronic deadbolt, and the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote. The DL3012 is the mechanical route, with a conventional 6-pin L4 keyway cylinder standard and interchangeable core available.
19) Which deadbolt should be used when only one face of the door can be bored?
The Callan Model 205S is a Grade 3 one-sided half-bore deadbolt, which takes a single-side prep. The Corbin Russwin DL3012 is a through-bored cylindrical deadlock keyed from both faces, for 1-3/4 inch to 2-1/4 inch doors, and it is non-handed so the same unit serves either swing.
20) If a lockset with an integrated deadbolt is wanted instead of a standalone deadlock, what is the option?
The Falcon H2101 is a Grade 2 entrance interconnected lock with a single cylinder deadbolt, so the knob or lever and the bolt come as one assembly. The Corbin Russwin DL3012 is a standalone deadlock with no latch trim, keyed from either side, which is the pairing used when a separate lockset or exit device already handles the latching.
21) What finishes does the Corbin Russwin DL3012 deadlock come in?
Six finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil-rubbed satin bronze, 625 bright chrome, and 626 satin chrome, plus BSP black suede powder coat. 626 satin chrome is the one to pick if you're matching the standard commercial lever and closer finish through the rest of the building; 613 and BSP are the ones people reach for on storefront and darker aluminum entrances.
22) How tough is the bolt on the Corbin Russwin DL3012 against someone sawing or forcing it?
The bolt is zinc diecast with a hardened steel insert, thrown 1 inch. The hardened insert is the part that matters against a hacksaw blade, and the full 1 inch projection is what keeps the bolt engaged in the frame if the door gets spread. Get the strike anchored into the frame reinforcement, not just the frame skin, or the throw is doing work the frame cannot hold.
