Medeco Maxum 11C61W Commercial Single Cylinder Deadbolt — Biaxial, G3 Keyway, Classroom Function

The Medeco Maxum 11C61W is a heavy-duty, ANSI/BHMA A156.36 Grade 1 single cylinder deadbolt engineered for demanding commercial applications where high-security key control and physical attack resistance are paramount. Built with solid-brass construction and UL 437 listed cylinders, this 6-pinned Biaxial deadbolt fits doors 1 3/8" to 2 1/2" thick and installs into a standard 2 1/8" crossbore and 1" edge bore (ANSI A115.13 prep). The G3 Keyway and Classroom Function configuration make it an ideal choice for educational facilities and other environments requiring controlled access with reliable egress.

Key Features

  • Door Thickness Compatibility: Fits doors 1 3/8" to 2 1/2" thick, accommodating a wide range of commercial door constructions.
  • Standard Door Prep: Designed for a standard 2 1/8" crossbore and 1" edge bore (ANSI A115.13 prep) for straightforward installation.
  • Solid-Brass Construction: Heavy-duty solid-brass body provides exceptional resistance to drilling, prying, and physical attack for long-term commercial reliability.
  • UL 437 Listed High-Security Cylinders: ANSI/BHMA A156.36 Grade 1 and UL 437 listed cylinders deliver maximum protection against picking, bumping, and other forms of physical attack.
  • Biaxial Key Control (M4 Technology): Patent-pending key control protects against unauthorized key duplication; M4 cylinders use cylinder side pins, a shuttle lift pin, and a movable key element to engage a sidebar, preventing the key from turning until elements are rotated and aligned correctly — guarding against bumping and picking.
  • Protection Against 3D Printing: A patent-pending movable element in the key deters unauthorized 3D printed copies of keys or blanks, providing a modern layer of security.
  • Special Angle Cut Keys: Requires a special key cutting machine and access to Medeco-specific blanks, available in a variety of restrictions to support every security need.
  • Master Keying Capabilities: M4 deadbolts can be master keyed into a system that includes M4, M4 BiLevel, and M4 CLIQ keys and cylinders, supporting extremely large keying systems.
  • Classroom Function: Cylinder x Thumbturn product function supports classroom-style operation for controlled access in educational and institutional environments.

Medeco MED-11C611W-26-G3P – Frequently Asked Questions

1) Will the Medeco Maxum 11C61W deadbolt fit a 2-inch thick door?
Yes. The Maxum 11C61W covers doors from 1-3/8 inches up to 2-1/2 inches thick, which is a wider band than most commercial deadbolts hold. That range takes in standard 1-3/4 inch commercial doors, older 1-3/8 inch interior doors, and thick custom or clad wood doors that usually force a special order. For comparison, the Accentra D111 Grade 1 deadbolt is listed for 1-3/8 to 1-3/4 inch doors only.
2) Does the Medeco Maxum 11C61W drop into an existing deadbolt prep, or does the door need new boring?
It goes into standard prep: a 2-1/8 inch crossbore and a 1 inch edge bore, per ANSI/BHMA A115.13. If the door already carries a bored deadbolt cut to that spec, the Maxum body drops in without new boring. Pick the bolt to match the hole you have, since both 2-3/8 inch and 2-3/4 inch backsets are offered, along with a drive-in bolt for doors with no faceplate mortise.
3) What backset and faceplate do I order on a Medeco Maxum 11C61W deadbolt?
Backset is 2-3/8 inches or 2-3/4 inches, and each comes with a 1 inch or a 1-1/8 inch faceplate, or as a drive-in bolt with no faceplate at all. Measure from the door edge to the center of the existing crossbore to settle the backset, then match the faceplate to the strike mortise already cut into the edge. There is also a less bolt assembly option if the bolt in the door is staying and only the trim and cylinder are being replaced.
4) Can the Medeco Maxum 11C61W be master keyed into an existing Medeco system?
Yes, and this is the reason most facilities buy it. The 11C61W is a 6-pin Biaxial cylinder on the G3 keyway, and M4 deadbolts master key into a system that also carries M4, M4 BiLevel, and M4 CLIQ cylinders. That lets one grand master cover mechanical deadbolts and electronic CLIQ openings in the same hierarchy. Order it Keyed Different, Keyed Alike, or to a specific key code if you are extending an existing system, and specify Pinned if you want it pinned at the factory or Sub-Assembled if your locksmith is pinning it to your system.
5) Is this Medeco Maxum deadbolt keyed on both sides or does it have a thumbturn inside?
Cylinder outside, thumbturn inside. The 11C61W is a single cylinder deadbolt, so anyone inside retracts the bolt by hand with no key, which is what classroom and institutional openings need for egress. If you need key operation on both faces, this is not the part, and there are double cylinder deadbolts for that, such as the Design Hardware D1 Series Grade 1 or the Dexter DB1000 double cylinder. Be aware that double cylinder deadbolts are restricted on egress doors in many jurisdictions.
6) Is the Medeco Maxum 11C61W actually pick and bump resistant, or is that marketing?
The cylinder is UL 437 listed, which is the standard that tests a cylinder against picking, drilling, and forced entry, and the hardware is ANSI/BHMA A156.36 Grade 1. Mechanically, the Biaxial M4 cylinder uses side pins, a shuttle lift pin, and a movable element in the key that has to rotate and align before the sidebar will release, so the plug will not turn on a lifted or bumped pin stack alone. The movable key element also frustrates 3D printed key copies. The body is solid brass with hardened steel inserts against drilling and prying.
7) Is this Medeco deadbolt right for a classroom door, or do I need a deadlock with a blank inside plate?
For a classroom door where staff must be able to get out without a key, the 11C61W is the right shape: keyed outside, thumbturn inside. Some school specs instead call for a cylinder by blank plate deadlock, where there is no inside operation at all, and the Corbin Russwin DL2211 Grade 1 cylindrical deadlock for 1-3/4 inch doors is that configuration. Read the spec on the drawing before you order, because the two are not interchangeable and only one satisfies a free egress requirement.
8) What is the Medeco G3 keyway and will my existing Medeco keys work with it?
G3 is the keyway on the 11C61W, and a Medeco key only enters a cylinder cut for its own keyway. If your building is already on G3 and you order to your key code, the new deadbolts join the existing system. If your site is on a different Medeco keyway, the 11C61W as configured will not accept those keys, so confirm your keyway before ordering a batch.
9) What is the closest Grade 1 classroom-function deadbolt alternative to the Medeco Maxum 11C61W?
The Falcon D111 is the nearest match on function and rating: it is a Grade 1 classroom deadbolt with cylinder x thumbturn operation and heavy duty rating, the same Grade 1, cylinder x thumbturn, heavy duty combination the Maxum 11C61W carries. The difference is the cylinder platform - the Maxum 11C61W is built on Medeco Biaxial technology with a G3 keyway, so if the building is already on a Medeco key system the D111 will not key into it.
10) Is there a simpler Grade 1 single cylinder deadbolt to use when high-security key control is not required?
The Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and a 6-pin cylinder, fitting doors 1-3/8 inch to 1-3/4 inch and carrying a fire rating. It covers the same classroom cylinder x thumbturn operation as the Maxum 11C61W on a conventional Schlage C keyway rather than the restricted Medeco G3 Biaxial platform, so keys can be cut on standard equipment. The Maxum 11C61W spans a wider door range, 1-3/8 inch to 2-1/2 inch.
11) What looks like a substitute for the Maxum 11C61W but is not a drop-in replacement?
Two to watch. The Arrow E60 is a Grade 2 exit deadlock that is non-keyed, blank plate x thumbturn - there is no key cylinder at all, so it cannot control access the way the keyed Maxum 11C61W does. The Corbin Russwin DL3211 is a Grade 1 cylindrical deadlock in a cylinder x blank configuration for 1-3/4 inch doors, which is keyed outside but has no inside thumbturn. The Maxum 11C61W is keyed with a cylinder x thumbturn arrangement, giving both key control outside and turn operation inside.
12) I need an interchangeable core deadbolt instead of the fixed-cylinder Medeco Maxum. What are my options?
The Maxum 11C61W uses a fixed cylinder on the Medeco Biaxial G3 platform. If the facility standardizes on interchangeable cores instead, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock prepped for SFIC less core, fitting doors 1-3/8 inch to 1-3/4 inch, and the Deltana CL200LAIC is a Grade 2 single cylinder deadbolt with interchangeable core prep and a 2-3/4 inch backset. The Delaney LM Series 301702 is a Grade 1 single cylinder less core deadbolt in dull chrome US26D, cylinder x thumbturn.
13) Which Grade 1 deadbolt carries a UL 3-hour fire rated latch as an alternative to the Medeco Maxum 11C61W?
The Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch, cylinder x thumbturn. The Maxum 11C61W is ANSI/BHMA A156.36 Grade 1 with UL 437 listed cylinders - UL 437 is an attack-resistance listing for the cylinder, a different qualification from a fire rating on the bolt. On a fire-rated opening, match the listing the drawing calls for.
14) Is the Accentra D111 the same thing as the Medeco Maxum 11C61W?
They overlap but are not identical. The Accentra D111 is a Grade 1 single cylinder deadbolt with cylinder x thumbturn function and a 2-3/8 inch backset, fitting doors 1-3/8 inch to 1-3/4 inch. The Maxum 11C61W is also Grade 1 cylinder x thumbturn, but covers doors 1-3/8 inch to 2-1/2 inch and is ordered with either a 2-3/8 inch or a 2-3/4 inch backset bolt. If the existing crossbore is on 2-3/4 inch centers, the D111 will not line up.
15) Should I order the Medeco Maxum deadbolt pinned or sub-assembled?
Pinned means the cylinder arrives keyed and ready to hang. Sub-Assembled means it ships without the pinning done, which is what a locksmith wants when the cylinder has to be pinned into an existing Medeco masterkey system on site. If you have no Medeco keying system and no shop pinning Medeco, order it Pinned with the keying option you need. Note that Medeco angle cut keys need a specific key cutting machine and access to restricted blanks, so sub-assembled only makes sense if your shop has both.
16) Do I need a Medeco key machine to get copies of these keys cut?
Yes, and that is the point of the system. Medeco keys are angle cut, so duplication takes a specific key cutting machine plus access to Medeco blanks, which come in a range of restriction levels. A hardware store cannot copy them. Plan your key control around an authorized dealer or an in-house shop set up for Medeco before you standardize a building on the 11C61W.
17) I need a Grade 1 commercial deadbolt but not high security key control. What else is there?
If drilling and forced entry resistance matter but restricted keying does not, the Grade 1 field has cheaper ways in. The Accentra D111 is Grade 1 cylinder by thumbturn with a 2-3/8 inch backset for 1-3/8 to 1-3/4 inch doors. The Falcon D111 is a Grade 1 heavy duty classroom deadbolt with an adjustable backset. The Dexter DB1000 single cylinder is Grade 1 for 1-3/8 to 1-7/8 inch doors. What you give up is the Medeco Biaxial cylinder, the UL 437 listing, and the patent-controlled blank that stops unauthorized duplication.
18) I only need to upgrade the cylinder on existing deadbolts. Do I have to buy the whole bolt assembly?
No. The Maxum 11C61W can be ordered less bolt assembly, which gives you the trim and the Medeco cylinder without a new bolt. That is the configuration for retrofitting doors where the bolt and strike in the door are sound and you are upgrading key control across a building. If the door prep is nonstandard or the existing bolt is worn, order a complete bolt instead and match the backset and faceplate to the door.
19) Can I order several Medeco Maxum deadbolts keyed alike for one building?
Yes. Keying is specified at order: Keyed Different for individual keys, Keyed Alike so one key runs a group of doors, or Key Code if you are matching an existing Medeco system and can supply the code. Property managers replacing a run of doors usually want Keyed Alike within a building and different across buildings; supply the key code if the doors are joining a system that is already cut.
20) What Grade 1 double cylinder deadbolt should I use instead of the single cylinder Maxum 11C61W on a glass-adjacent door?
The Maxum 11C61W is a single cylinder deadbolt, keyed outside with a thumbturn inside. Where both sides must be keyed, the Design Hardware D1 Series is a Grade 1 double cylinder deadbolt rated extra heavy duty 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 doors. Double cylinder operation requires a key on the inside as well, so confirm the local egress code for the occupancy before specifying either.
21) What should I use if I want keypad or credential access instead of a keyed Medeco deadbolt?
The Maxum 11C61W is a keyed mechanical deadbolt on the Medeco Biaxial G3 platform. For credential-based access on the same opening type, the Codelocks CL2200 is an electronic surface deadbolt in brushed steel, medium duty, and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override. The Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote. None of these key into a Medeco system, so a facility standardizing on Medeco keying would be splitting its key control.
22) Is there an ADA-friendly thumbturn deadbolt alternative to the Medeco Maxum 11C61W?
The Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn, cylinder x thumbturn, for doors 1-3/8 inch to 1-3/4 inch. The Maxum 11C61W is a Grade 1 heavy duty cylinder x thumbturn deadbolt covering 1-3/8 inch to 2-1/2 inch doors, so the two sit at different ANSI/BHMA grades - check whether the opening is specified to Grade 1 before swapping in the LSD for the turn style.
23) Which single cylinder deadbolts come in a 2-3/4 inch backset like the Maxum 11C61W?
The Maxum 11C61W is ordered with either a 2-3/8 inch or 2-3/4 inch backset bolt, in 1 inch or 1-1/8 inch faceplate or drive-in styles. Among comparable single cylinder deadbolts, the Deltana CL200LA is a Grade 2 single deadbolt with a 2-3/4 inch backset, and the Deltana CL200LAIC is the same 2-3/4 inch backset in an interchangeable core version. The Brinks Raleigh E2401 uses a 4-way adjustable backset, cylinder x thumbturn, which covers either center.
24) What finishes does the Medeco Maxum commercial deadbolt come in to match the rest of my building's hardware?
Thirteen finishes, so matching an existing fleet is usually possible: 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, 622 Flat Black, 625 Bright Chrome, and 626 Satin Chrome. For commercial interiors, 626 satin chrome and 630-family satin finishes are the usual match on institutional openings; 613 and 622 are the common exterior and storefront choices.
