Medeco Maxum 11C62 Commercial Trim Double Cylinder 6-Pinned Deadbolt with DL Keyway

The Medeco Maxum 11C62 is a heavy-duty, ANSI/BHMA A156.36 Grade 1 certified double cylinder deadbolt engineered for high-security commercial and residential applications. Featuring a 6-pinned configuration with DL Keyway, this lock accommodates door thicknesses from 1-3/8" to 2-1/2" and requires a standard 2-1/8" crossbore and 1" edge bore (ANSI A115.13). Built with a hardened brass body, drill-resistant pins, and a 1" hardened steel bolt in a heavy-gauge steel housing, the Maxum deadbolt delivers unmatched resistance to prying, wrenching, drilling, and kick-in attacks. UL 437 Listed and backed by Medeco's patented sidebar technology, this lock is the definitive choice for facilities demanding strict key control and superior physical security.

Key Features

  • Door Thickness Compatibility: Designed for doors ranging from 1-3/8" to 2-1/2" thick, accommodating a wide variety of commercial and residential door constructions.
  • Standard Bore Preparation: Requires a 2-1/8" crossbore and 1" edge bore per ANSI A115.13, ensuring compatibility with standard door prep across most commercial applications.
  • 1" Hardened Steel Bolt: Features a 1" hardened steel bolt housed in a heavy-gauge steel housing for maximum resistance to forced entry including kick-ins and prying.
  • Patent-Pending Key Control (Medeco 4): Restricts unauthorized key duplication — special angle-cut keys require unique Medeco equipment and can only be duplicated by authorized dealers.
  • Sidebar Technology: Keys must be properly aligned and rotated to operate, providing superior picking and bumping protection beyond standard pin tumbler designs.
  • Movable Element Key Design: A movable element in the key deters illegal 3D printing of key blanks, adding a modern layer of key security.
  • Master Keying & System Compatibility: Supports master keying for multi-level access control and is compatible with Medeco's M4, M4 BiLevel, and M4 CLIQ systems.
  • Keyed Alike Capability: Easily supports keyed alike configurations across multiple doors and facilities for simplified access management.
  • Double Cylinder Configuration: Available in double cylinder format; the captive thumbturn option allows the internal mechanism to be quickly changed from thumbturn to keyed access only for high-security unoccupied facility use.
  • Hardened Brass Body with Drill-Resistant Pins: Strategically placed drill-resistant pins and a hardened brass body resist physical attacks including drilling, wrenching, and prying.

Medeco MED-11C621T-26-DLT – Frequently Asked Questions

1) Will the Medeco Maxum 11C62 deadbolt fit a 2-inch thick door?
Yes. The Maxum 11C62 covers door thicknesses from 1-3/8 inches all the way to 2-1/2 inches, so a 2 inch door is well inside its range. That top end is unusual for a bored deadbolt and is the reason it turns up on heavy commercial and institutional doors that a standard 1-3/8 to 1-3/4 inch deadbolt won't cover.
2) What door prep does the Medeco 11C62 deadbolt need, and will it drop into an existing bore?
Standard prep: a 2-1/8 inch crossbore and a 1 inch edge bore, per ANSI/BHMA A115.13. That is the same prep most commercial bored deadbolts use, so if the door already has a deadbolt in a standard 2-1/8 inch bore, the 11C62 goes into the existing hole. Confirm the backset on the door, 2-3/8 or 2-3/4 inch, and order the matching bolt option.
3) What backset and faceplate options does the Medeco Maxum 11C62 come in?
Bolt assemblies come in 2-3/8 inch and 2-3/4 inch backsets, each offered with a 1 inch faceplate, a 1-1/8 inch faceplate, or drive-in (no faceplate, for doors prepped without a mortised face). There is also a Less Bolt Assembly option if you are reusing a bolt already in the door or ordering the trim alone. Measure from the door edge to the center of the crossbore to get the backset right before you order.
4) Should I use a double cylinder deadbolt or a single cylinder with a thumbturn?
A double cylinder deadbolt like the Maxum 11C62 takes a key on both sides, so nobody can throw or retract the bolt without a key. That is what you want on a glass-adjacent door where an intruder could reach the inside, or on an unoccupied high-security space. The tradeoff is egress: many jurisdictions restrict key-both-sides on a required exit door because occupants need a key to get out. Where you need free egress, use a cylinder x thumbturn instead, such as the Falcon D111 Grade 1 or the Dexter DB1000 Series single cylinder, both Grade 1 like the Medeco.
5) Is the Medeco 11C62 Maxum deadbolt ANSI Grade 1 and UL listed?
Grade 1 under ANSI/BHMA A156.36 and UL 437 Listed, with a Heavy Duty rating. UL 437 is the key-control and attack-resistance listing, which is what a spec calling for a high-security cylinder is usually asking for; A156.36 Grade 1 is the auxiliary lock durability grade. Both are stated for the 11C62, so it satisfies specs that name either.
6) Can I get Medeco Maxum deadbolts keyed alike across a building?
Yes, and it is the usual reason people buy them. Keying is a required choice at order: keyed different, keyed alike, or to a specific key code you supply. Keyed alike puts one key on every door in the group; a key code lets you add doors to a system already installed. The 11C62 also master keys, so you can run a grand master over tenant or department keys. All of it runs on the 6-pin DL keyway, so every lock in the group has to be on that same keyway.
7) Will a Medeco DL keyway deadbolt work with keys we already have?
Only if your existing Medeco system is on the DL keyway. The 11C62 is 6-pinned on DL, and Medeco keyways are restricted, so it will not accept a Schlage C, Kwikset, or any other manufacturer's key. Blanks are angle-cut and duplication is limited to authorized dealers, which is the point of the system. If your building runs a different keyway, you need cylinders in that keyway rather than this one. Where you just want a commercial deadbolt on a common keyway, the Hager 3214 double cylinder is offered with a Schlage C keyway.
8) What is the difference between the Medeco Maxum 11C62 and a standard Grade 1 commercial deadbolt?
Grade and function are the same on paper: the Design Hardware D1 Series and the Dexter DB1000 are both Grade 1 double cylinder deadbolts too. The difference is the cylinder. The Maxum is UL 437 Listed with a sidebar that requires keys to be rotated as well as lifted, drill-resistant pins, and restricted angle-cut blanks. Buy the Medeco when key control is the requirement, someone must not be able to copy a key at a hardware store. Buy the Design Hardware D1 or Dexter DB1000 when you need a Grade 1 double cylinder and the keying is ordinary. Note the D1 is listed for 1-3/4 inch doors and the DB1000 for 1-3/8 to 1-7/8 inch, both narrower ranges than the Medeco.
9) What is the closest Grade 1 double cylinder deadbolt to the Medeco Maxum 11C62 if a restricted Medeco keyway is not needed?
The Design Hardware D1 Series double cylinder deadbolt is a Grade 1 double cylinder deadbolt rated extra heavy duty for 1-3/4 inch doors. The Dexter DB1000 double cylinder is also Grade 1 double cylinder and covers doors 1-3/8 inch to 1-7/8 inch. The Medeco Maxum 11C62 is Grade 1 double cylinder as well, with a 6-pinned DL keyway cylinder for restricted key control; the Design Hardware and Dexter units are conventional keyed deadbolts, so choose by whether the facility needs key duplication control or just the double cylinder function and grade.
10) What double cylinder deadbolt works on a door thicker than 1-3/4 inches?
The Medeco Maxum 11C62 fits doors 1-3/8 inch to 2-1/2 inch thick, which covers thick commercial and storefront doors. Among conventional double cylinder deadbolts, the Deltana 7312KA2 is a Grade 3 double cylinder rated for 1-3/8 inch to 2 inch doors, and the Dexter DB1000 double cylinder covers 1-3/8 inch to 1-7/8 inch. The Design Hardware D1 double cylinder is specified for 1-3/4 inch doors only, so measure the leaf before ordering it.
11) I need a thumbturn on the inside instead of a second cylinder - what should I order?
The Medeco Maxum 11C62 is keyed on both sides as a double cylinder deadbolt, so it will not give an inside thumbturn. For a Grade 1 cylinder by thumbturn deadbolt, the Accentra D111 is Grade 1 with a 2-3/8 inch backset for doors 1-3/8 inch to 1-3/4 inch, the Falcon D111 is a Grade 1 heavy duty classroom deadbolt with adjustable backset, and the Delaney LM Series is a Grade 1 single cylinder less core deadbolt in dull chrome US26D. Egress codes in many jurisdictions restrict double cylinder deadbolts on required exit doors, which is the usual reason to switch to a thumbturn.
12) What is the difference between the Medeco Maxum 11C62 and a Corbin Russwin DL3011 deadlock?
Both are keyed deadbolts for commercial openings, but they are prepped differently. The Medeco Maxum 11C62 is a bored deadbolt taking a standard 2-1/8 inch crossbore and 1 inch edge bore per ANSI A115.13, with backset choices of 2-3/8 inch and 2-3/4 inch and keyed cylinders on both faces. The Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock in cylinder by blank configuration for doors 1-3/4 inch to 2-1/4 inch, meaning one side is keyed and the other is a blank plate with no operation. If the interior face must stay inoperable rather than keyed, the DL3011 is the correct function; if both sides must be keyed, it is not a substitute.
13) Is a Hager 3214 double cylinder deadbolt a drop-in equivalent for a Medeco Maxum 11C62?
They are not the same specification. The Hager 3214 is a Grade 2 double cylinder deadbolt with a Schlage C keyway for doors 1-3/8 inch to 1-3/4 inch and carries a fire rating. The Medeco Maxum 11C62 is Grade 1, fits 1-3/8 inch to 2-1/2 inch doors, and uses a 6-pinned DL keyway on Medeco 4 cylinder technology, so it will not key into an existing Schlage C system. Where an opening is already mastered on Schlage C, the Hager 3214 keys into that system; where a restricted Medeco key system is being extended, the 11C62 is the one that matches the keys.
14) Do any comparable deadbolts carry a fire rating like the Medeco Maxum?
Among the commercial deadbolts, the Hager 3115, 3118, 3214, and 3215 all carry a fire rating and cover doors 1-3/8 inch to 1-3/4 inch, and the Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch. The Medeco Maxum 11C62 is UL 437 listed and ANSI/BHMA A156.36 Grade 1 certified, which speaks to key control and physical attack resistance. If the opening is a rated door assembly, specify from the fire rated group above.
15) How much does the bolt throw on the Medeco Maxum 11C62, and will it hold up to a kick-in?
One inch of hardened steel bolt in a heavy-gauge steel housing. A full 1 inch throw is what gets the bolt deep enough into the frame that the door cannot be spread and popped, and it is the throw commercial specs generally call for. Attack resistance also comes from the hardened brass body and drill-resistant pins in the cylinder. The strike still decides the outcome, so anchor it into the stud, not just the jamb.
16) What does the Pinning option mean when ordering a Medeco Maxum deadbolt?
It controls how much work is done before the lock ships. Pinned means the cylinder arrives loaded to your keying. Sub-Assembled ships it for a locksmith to pin on site, which is what you order when you are keying into your own Medeco system in-house. Sub-Assembled, No Slider leaves the sidebar slider component out as well. If you do not have a Medeco-authorized shop doing the pinning, order it Pinned.
17) Can a Medeco Maxum deadbolt be tied into an electronic access or audit trail system?
The 11C62 is a mechanical deadbolt, but its cylinder platform is Medeco 4 (M4) and it works within M4, M4 BiLevel, and M4 CLIQ systems. CLIQ is the electromechanical layer that gives you audit trail and scheduled key privileges without wiring the door. That means you can install mechanical now and move specific doors onto CLIQ later while keeping one keying system. Available Technology also lists Bilevel and M3 builds if you are matching an older Medeco system already in the building.
18) I need a double cylinder deadbolt but not high-security keying. What are cheaper alternatives?
Several, at lower grades. The Hager 3214 is a Grade 2 double cylinder on a Schlage C keyway for 1-3/8 to 1-3/4 inch doors. The Dexter DB2000 is a Grade 2 double cylinder for the same thickness range. The Delaney LU Series is a Grade 2 double cylinder in stainless (US32D). The Callan 210S is Grade 3. Step down and you give up the UL 437 listing and the restricted keyway, which is exactly what the Maxum is for, so keep the Medeco on doors where key duplication is the actual risk.
19) Does the Medeco Maxum 11C62 have a thumbturn on the inside?
No. It is keyed on both sides, so there is no thumbturn. Medeco does build a captive thumbturn arrangement that can be switched from thumbturn to keyed-only for unoccupied high-security spaces, but the 11C62 as configured is double cylinder. If someone on the inside needs to operate it without a key, you want a cylinder x thumbturn deadbolt instead, for example the Falcon D111 in Grade 1.
20) Is the Medeco Maxum deadbolt suitable for apartment and multi-tenant properties?
It is built for it, and the reason is turnover. A Medeco DL keyway is restricted, so a tenant cannot walk out and cut copies, which is the failure mode that forces a rekey on every move-out. Keyed alike groups let you run one key across common doors, and master keying gives staff a key that works building-wide while each unit stays separate. The wide 1-3/8 to 2-1/2 inch thickness range means one model covers unit doors, mechanical rooms, and heavier exterior doors.
21) What is a lighter duty alternative to a Medeco Maxum double cylinder deadbolt for interior or low traffic openings?
For openings that do not need Grade 1 or restricted keying, the Dexter DB2000 double cylinder deadbolt is Grade 2 for doors 1-3/8 inch to 1-3/4 inch, the Delaney LU Series double cylinder is Grade 2 in stainless steel US32D finish, and the Callan 210S is a Grade 3 double cylinder. The Medeco Maxum 11C62 is Grade 1 heavy duty with a 6-pinned DL keyway, which is what a facility specifies when key control and attack resistance drive the selection.
22) Which of these deadbolts looks like a substitute for a Medeco Maxum 11C62 but is not?
Several items sit near it in a search and solve a different problem. The Baldwin Reserve 8BR0618001 is a deadbolt spacer, not a lock. The BEST 8T is a T Series tubular deadbolt tube component rather than a complete deadbolt. The Arrow 460 is a mortise lock strike for latchbolt and deadbolt functions, hardware for the frame side. The Arrow E60 is a Grade 2 non-keyed exit deadlock, blank plate by thumbturn, with no cylinder at all. The Medeco Maxum 11C62 is a complete keyed deadbolt with cylinders on both faces, so none of those four replace it.
23) What deadbolt should I use if I want to change the cylinder without pulling the lock off the door?
The Medeco Maxum 11C62 uses a fixed cylinder in a 6-pinned DL keyway. If interchangeable core is the requirement, the Arrow E61 is a Grade 2 single cylinder deadlock with SFIC prep supplied less core for doors 1-3/8 inch to 1-3/4 inch, the Deltana CL200LAIC is a Grade 2 single cylinder interchangeable core deadbolt with a 2-3/4 inch backset, and the Delaney LM Series is a Grade 1 single cylinder less core deadbolt. All three are single cylinder, so they give a thumbturn side rather than a second keyed face.
24) What is an alternative to a keyed Medeco deadbolt when access needs to be by code or credential instead of a key?
The Medeco Maxum 11C62 is a mechanical keyed deadbolt built around the Medeco 4 restricted key system. Where credential based access is wanted instead, the Codelocks CL2200 is a medium duty electronic surface deadbolt, the Codelocks CL200 is a light duty surface deadbolt with key override, the Dormakaba Saffire LX-D is an RFID electronic deadbolt with Bluetooth and electronic lock override, and the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote. Note that the surface mounted Codelocks units do not use the 2-1/8 inch crossbore prep the 11C62 takes, so the door prep differs.
25) Is there an ADA friendly deadbolt option instead of the Medeco Maxum double cylinder?
The Medeco Maxum 11C62 is keyed on both faces, so operating it always requires a key. The Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn for doors 1-3/8 inch to 1-3/4 inch, which is the option when the inside must be operable without a key or tight grasp. It is a Grade 3 residential and light commercial deadbolt rather than a Grade 1 heavy duty unit.
26) The door only has one bore and no room for a second - what deadbolt fits?
The Medeco Maxum 11C62 needs a standard 2-1/8 inch crossbore plus a 1 inch edge bore. Where the door cannot take full prep, the Callan 205S is a Grade 3 one-sided half-bore deadbolt, and the Codelocks CL200 is a light duty surface mounted deadbolt with key override that installs on the face of the door. The Detex DX Series is a hinge side locking deadbolt with multi-point security for a different attack path entirely.
27) What finishes does the Medeco Maxum 11C62 deadbolt come in to match existing hardware?
Thirteen finishes, covering the common commercial BHMA numbers and the decorative ones: 626 satin chrome and 625 bright chrome, 605 bright brass, 606 satin brass, 609 antique brass, 611 bright bronze, 612 satin bronze, 613 dark bronze oil-rubbed, 624 dark bronze, 618 bright nickel, 619 satin nickel, 20 antique nickel, and 622 flat black. If you are matching a building standard, 626 is the typical commercial default and 613 the usual match for oil-rubbed bronze levers.
28) Which double cylinder deadbolt matches decorative or residential trim rather than commercial trim?
The Medeco Maxum 11C62 is a commercial trim deadbolt offered in finishes including 605 bright brass, 613 dark bronze oil-rubbed, 622 flat black, and 626 satin chrome. For a decorative look on the same double cylinder function, the Baldwin Reserve contemporary round and contemporary square deadbolts are both double cylinder, the Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt, and the Emtek 8323 Modern Disc is a brass double cylinder deadbolt. Those are styled trims; the Maxum keeps commercial trim with the Medeco 4 cylinder.
