Medeco MED-11C601T-26-DLT – Frequently Asked Questions

1) Will the Medeco 11C60 Maxum deadbolt fit a door already bored for a standard tubular deadbolt?
In most cases yes. The 11C60 Maxum uses the standard ANSI/BHMA A115.13 preparation: a 2-1/8 inch crossbore through the face and a 1 inch edge bore. That is the same prep the majority of commercial bored deadbolts use, so it drops into an existing hole without redrilling the face. Door thickness range is 1-3/8 to 2-1/2 inches, which covers 1-3/4 inch commercial doors, older 1-3/8 inch interior doors, and thicker custom entries. What you still have to match is backset, which the bolt option sets.
2) What backset and bolt do I have to specify when ordering a Medeco 11C60 deadbolt?
Backset is the distance from the door edge to the center of the crossbore, and the 11C60 is offered in both common ones, 2-3/8 inch and 2-3/4 inch. Each backset comes three ways: with a 1 inch faceplate, with a 1-1/8 inch faceplate, or as a drive-in bolt. Pick the faceplate width that matches the mortise already cut into the door edge, otherwise you are chiseling. The drive-in bolt has no faceplate at all and suits doors prepped for a drive-in collar, which is common on metal and prehung units. There is also a Less Bolt Assembly option if you are supplying the bolt yourself.
3) Does the Medeco 11C60 satisfy a spec calling for a Grade 1 high security deadbolt?
It does. The 11C60 Maxum is certified ANSI/BHMA Grade 1 under A156.36 and is UL 437 Listed for high security, and it is classed heavy duty for commercial use. Construction is solid brass with hardened steel inserts, aimed at drilling, prying and forced entry. UL 437 is the piece that separates it from a plain Grade 1 deadbolt: Grade 1 speaks to strength and cycle performance, UL 437 to attack resistance at the cylinder, including picking and drilling.
4) Can Medeco 11C60 deadbolts be put on a master key system across an apartment building or campus?
Yes, the Maxum 11C60 is built for large-scale master key systems, so one master can cover a property's deadbolts while each unit keeps its own change key. It is a 6-pin cylinder on Medeco's DL keyway, and it is offered in both M3 and Bilevel technology. Match the technology and keyway your existing Medeco system already runs on. That is the thing that decides whether new locks join the existing system or start a second one nobody wants to carry keys for.
5) There is glass beside the door within arm's reach of the turn. What replaces the Medeco 11C60 Maxum there?
The Medeco 11C60 Maxum is a single cylinder deadbolt with cylinder x thumbturn function, so the inside is a turn rather than a keyed cylinder. For a keyed-both-sides opening, the Design Hardware D1 is a Grade 1 extra heavy duty double cylinder deadbolt for 1-3/4 inch doors, the Dexter DB1000 double cylinder is Grade 1 for 1-3/8 inch to 1-7/8 inch doors, and the Hager 3214 is a Grade 2 double cylinder deadbolt for 1-3/8 inch to 1-3/4 inch doors. Confirm the egress code for the occupancy before specifying keyed-both-sides on an exit door.
6) The door is 2-1/4 inches thick. Which of these deadbolts will actually fit it?
The Medeco 11C60 Maxum fits door thicknesses from 1-3/8 inches to 2-1/2 inches, so a 2-1/4 inch door is inside its range. Among the comparable commercial deadbolts, the Corbin Russwin DL3011 Grade 1 cylindrical deadlock covers 1-3/4 inches to 2-1/4 inches, but its function is cylinder x blank, meaning keyed outside with no inside thumbturn. The other Grade 1 bored deadbolts stop well short of a 2-1/4 inch door: the Dexter DB1000 single cylinder covers 1-3/8 inches to 1-7/8 inches, the Accentra D111 covers 1-3/8 inches to 1-3/4 inches, and the Corbin Russwin DL3211 and the Design Hardware D1 are built for 1-3/4 inch doors.
7) What is the closest Grade 1 single cylinder deadbolt to the Medeco 11C60 Maxum when the opening does not call for a high-security cylinder?
The Medeco 11C60 Maxum is a Grade 1, heavy duty, cylinder x thumbturn deadbolt built around a 6-pinned DL keyway cylinder with UL437 high-security listing. If the specification only calls for Grade 1 mechanical performance on a standard cylinder, the Accentra D111 is a Grade 1 cylinder x thumbturn deadbolt with a 2-3/8 inch backset for 1-3/8 inch to 1-3/4 inch doors, the Falcon D111 is a Grade 1 heavy duty cylinder x thumbturn deadbolt with an adjustable backset, and the Dexter DB1000 single cylinder is Grade 1 cylinder x thumbturn for 1-3/8 inch to 1-7/8 inch doors. The Deltana CL200LM is another Grade 1 single cylinder option in the same function. The difference is the cylinder: the Maxum carries the DL keyway and Medeco key control, while those four use conventional cylinders.
8) Our facility runs small format interchangeable cores. What takes the place of the Medeco 11C60 Maxum on an SFIC keying program?
The Medeco 11C60 Maxum is supplied as a fixed cylinder on the DL keyway, so it is keyed into a Medeco system rather than an interchangeable core program. For an SFIC or less-core housing, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock supplied with SFIC prep less core for 1-3/8 inch to 1-3/4 inch doors, the Delaney LM Series 301702 is a Grade 1 single cylinder less core deadbolt in dull chrome US26D, and the Deltana CL200LAIC is a Grade 2 interchangeable core deadbolt with a 2-3/4 inch backset. All three ship without a core so your existing cores drop in.
9) The building keys everything on Schlage C. Which comparable deadbolt matches that keyway instead of the Medeco DL?
The Medeco 11C60 Maxum is a 6-pinned cylinder on the DL keyway, which is a Medeco restricted keyway and will not accept a Schlage C key. On Schlage C, the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and 6-pin cylinder for 1-3/8 inch to 1-3/4 inch doors, and the Hager 3115 is a Grade 2 cylinder x thumbturn deadbolt on the Schlage C keyway across the same thickness range. If the opening needs keyed-both-sides on Schlage C, the Hager 3214 is a Grade 2 double cylinder deadbolt on that keyway.
10) Which of these commercial deadbolts carry a fire rating for a rated opening?
Read the two listings carefully because they cover different things. The Medeco 11C60 Maxum is UL437 listed, which is an attack-resistance listing covering drilling, prying, picking and bumping, and it is ANSI/BHMA A156.36 Grade 1. Where the rated assembly is the governing requirement, the Hager 3118 Grade 1 classroom deadbolt carries a fire rating, as do the Hager 3115, 3214 and 3215 Grade 2 deadbolts, all for 1-3/8 inch to 1-3/4 inch doors. The Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch.
11) The door has no 2-1/8 inch crossbore. What deadbolt suits it instead of the Medeco 11C60 Maxum?
The Medeco 11C60 Maxum needs a standard 2-1/8 inch crossbore and 1 inch edge bore per ANSI/BHMA A115.13, which means a bored door prep. Where the door is prepped for a mortise case instead, the Dormakaba D900 is a small case mortise deadbolt with cylinder x thumbturn function, and the Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch in square and round trim. Where the door cannot be bored at all, the Codelocks CL200 is a surface-mounted deadbolt with key override, and the Codelocks CL2200 is a medium duty electronic surface deadbolt in brushed steel.
12) Can I order the Medeco 11C60 sub-assembled so my locksmith pins it to our system?
Yes. Three pinning choices are offered on the 11C60 Maxum: Pinned, Sub-Assembled, and Sub-Assembled No Slider. Pinned arrives ready to hang. The two sub-assembled versions are for shops that pin to their own system, with the No Slider version supplied without the slider element. All three are 6-pin on the DL keyway, so the shop keying them needs Medeco DL blanks and the right pinning kit for the technology you pick, M3 or Bilevel.
13) What is the difference between the M3 and Bilevel versions of the Medeco 11C60 Maxum deadbolt?
They are the two cylinder platforms the 11C60 is built on, and the choice is driven by what you already own rather than by the deadbolt itself. Both are 6-pin on the DL keyway. If the property is already on a Medeco system, order the same technology it runs so the new deadbolts key into the existing hierarchy; ordering the other one gives you a lock that works fine but takes a different key. If this is a fresh installation with no legacy keys, either is a clean start.
14) What does Less Bolt Assembly mean on the Medeco 11C60 order form?
Less Bolt Assembly ships the 11C60 Maxum without a bolt, so pick it only when a bolt of the correct backset is already in the door or is being supplied separately. For a normal install choose one of the six complete bolt options instead: 2-3/8 or 2-3/4 inch backset, each with a 1 inch faceplate, a 1-1/8 inch faceplate, or drive-in. Order Less Bolt Assembly by mistake and you get the outside cylinder and inside thumbturn with nothing to throw into the strike.
15) I need a Grade 1 commercial deadbolt but not high security pricing. What else works?
The Medeco 11C60 Maxum earns its keep on UL 437 attack resistance and restricted key control; if the opening does not need that, other Grade 1 single cylinder deadbolts of the same cylinder x thumbturn function include the Delaney LM Series, supplied less core so you drop in your own cylinder, the Deltana CL200LM, and the Dexter DB1000 single cylinder for 1-3/8 to 1-7/8 inch doors. What you give up is the UL 437 listing and Medeco's duplication control, which matter most on perimeter and tenant doors.
16) Can a tenant get a Medeco 11C60 key copied at a hardware store?
Key control is the reason the Maxum exists. The 11C60 runs Medeco's DL keyway with a 6-pin cylinder, and the Maxum key control technology is built to stop unauthorized duplication, including replication by 3D printing through a movable element in the key. Practically, that means the keys stay under your control rather than being cut from a blank off a rack, which is what makes it worth specifying on tenant entries, records rooms and back-of-house doors.
17) Are the Arrow E60 and the Corbin Russwin cylindrical deadlocks drop-in alternatives to a Medeco Maxum deadbolt?
No, and the difference is function, not grade. The Medeco 11C60 Maxum is cylinder x thumbturn: key from the outside, thumbturn on the inside. The Arrow E60 is a Grade 2 exit deadlock with a blank plate x thumbturn function for 1-3/8 inch to 1-3/4 inch doors, so there is no key cylinder on the outside at all and it can only be operated from the inside. The Corbin Russwin DL3011, DL3211 and DL2211 are Grade 1 cylindrical deadlocks with a cylinder x blank function, keyed from the outside with no inside turn. Anyone expecting to retract the bolt by hand from inside will find those three do not.
18) What is a lighter-duty single cylinder deadbolt than the Medeco 11C60 Maxum for interior or low-traffic openings?
The Medeco 11C60 Maxum is a Grade 1 heavy duty commercial deadbolt. In the same cylinder x thumbturn function at Grade 2 there is the Dexter DB2000 single cylinder for 1-3/8 inch to 1-3/4 inch doors, the Arrow DBX61, the Falcon D211 medium duty classroom function deadbolt, the Hager 3215 with a 1 inch throw, and the Cal-Royal CB160, which adds a tamper-resistant cylinder guard. At Grade 3, the Cal-Royal ED500 and the Callan 200S cover 1-3/8 inch to 1-3/4 inch openings in the same function.
19) Which deadbolt has a thumbturn a resident with limited hand strength can operate?
The Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn, for doors 1-3/8 inches to 1-3/4 inches thick. The Medeco 11C60 Maxum is also a cylinder x thumbturn deadbolt but its selection is driven by Grade 1 performance and UL437 high-security cylinder protection, so on an accessible unit door where the turn shape governs, the LSD addresses that directly. The Cal-Royal ED500 is another Grade 3 cylinder x thumbturn option across the same 1-3/8 inch to 1-3/4 inch range.
20) We want to stop issuing keys entirely. What replaces a keyed Maxum deadbolt with a credential or code?
The Medeco 11C60 Maxum is a mechanical keyed deadbolt on the DL keyway. For keyless operation on a similar opening, the Codelocks CL2210 is an electronic mortise deadbolt, the Codelocks CL2200 is a medium duty electronic surface deadbolt in brushed steel, and the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote. For credential-based multifamily and hospitality programs, the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override, and the Dormakaba Nova-D is an RFID multihousing smart electronic deadbolt.
21) The deadbolt has to release from the access control system. What do I use instead of a Medeco Maxum?
The Medeco 11C60 Maxum is a mechanical bored deadbolt with key outside and thumbturn inside, so it does not tie into a card reader or release circuit. For an electrically released bolt, the DynaLock 1300 Series is a heavy duty mortise electric deadbolt. Where the opening needs the bolt on the hinge side or more than one locking point, the Detex DX Series provides hinge side locking dead bolts with multi-point security. Both are selected around the control system rather than around a keyway.
22) What finishes does the Medeco 11C60 Maxum deadbolt come in to match the rest of a building's hardware?
Thirteen finishes, enough to match most existing schedules: 605 Bright Brass, 606 Satin Brass, 609 Antique Brass, 611 Bright Bronze, 612 Satin Bronze, 613 Dark Bronze Oil-Rubbed, 618 Bright Nickel, 619 Satin Nickel, 20 Antique Nickel, 622 Flat Black, 624 Dark Bronze, 625 Bright Chrome and 626 Satin Chrome. Commercial jobs usually land on 626 Satin Chrome or 613, since those are the two that sit alongside most existing lever and exit hardware.
23) I do not have the backset confirmed yet. Which deadbolts handle either backset without picking one at order time?
The Medeco 11C60 Maxum is ordered with the backset selected up front, in 2-3/8 inch or 2-3/4 inch, each with a 1 inch or 1-1/8 inch faceplate, plus drive-in and less bolt assembly options. If the backset cannot be confirmed before the truck rolls, the Falcon D111 is a Grade 1 heavy duty deadbolt with an adjustable backset, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset, and the Brinks Raleigh E2401 and Mendocino E2402 use a 4-way adjustable backset in round and square trim.
24) Can I order an Arrow 460 or a BEST 8T as a substitute deadbolt?
Neither one is a deadbolt you can hang on a door. The Arrow 460 is a mortise lock strike for latchbolt x deadbolt functions with a straight lip, so it is the strike side of the opening. The BEST 8T is a T Series tubular deadbolt tube component, a bolt assembly rather than a complete lock. The Baldwin 8BR0618001 is a deadbolt spacer. The Medeco 11C60 Maxum is a complete single cylinder deadbolt with the cylinder, thumbturn and bolt assembly selected together, with a less bolt assembly option when the existing bolt is being reused.
25) The entry needs decorative trim to match the rest of the suite. How does the Medeco Maxum compare to the decorative deadbolts?
The Medeco 11C60 Maxum comes in thirteen finishes including 605 Bright Brass, 609 Antique Brass, 613 Dark Bronze Oil-Rubbed, 622 Flat Black, 624 Dark Bronze and 626 Satin Chrome, so it covers standard architectural finishes while staying a Grade 1 commercial deadbolt. If the trim shape itself is the driver, the Emtek #11 Tuscany is a lost wax cast bronze cylinder x thumbturn deadbolt, the Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt, and the Bravura 310RC Elite and 310SC Elite are Grade 2 contemporary round and square deadbolts in the same cylinder x thumbturn function.
