Medeco 100400H 6-Pin 1-1/8" Rim Cylinder with Horizontal/Vertical Tailpiece — UL 437 Listed High Security

The Medeco 100400H is a heavy-duty, commercial-grade 6-pin rim cylinder measuring 1-1/8" and featuring a horizontal/vertical tailpiece for broad compatibility with auxiliary rim locks including surface-mounted deadbolts, night latches, panic devices, and jimmyproof locks (also known as vertical dropbolts or interlocking deadbolts). Constructed from brass and rated Grade 1, this cylinder is UL 437 listed for drill and pick resistance, delivering high-security performance for demanding commercial applications. Medeco's patented Medeco 4 (M4) design provides utility-patented key control, protecting against unauthorized key duplication while integrating seamlessly into existing hardware configurations.

Medeco MED-100400H-26-00P-Y02 – Frequently Asked Questions

1) Will a Medeco 100400H rim cylinder work on a jimmyproof / vertical dropbolt lock?
Yes. The 100400H is a 1-1/8 inch rim cylinder with a horizontal/vertical tailpiece, and that dual-orientation tailpiece is what lets it drive jimmyproof (interlocking deadbolt) locks as well as surface-mounted deadbolts, night latches, and rim panic devices. The vertical dropbolt style is the one people get wrong most often, because it needs the tailpiece turned to the vertical orientation rather than the horizontal one used on most rim exit devices. You pick the orientation you need on the order, Horizontal or Vertical.
2) What do I have to specify when ordering a Medeco 100400 rim cylinder?
Five things settle the order on the 100400 rim cylinder. Keying, which is required: Keyed Different, Keyed Alike, or by Key Code. Key technology: Biaxial, Bilevel, KeyMark, M3, or Original. Tailpiece orientation, Horizontal or Vertical. Rim tailpiece part, CT-Y02 or CT-Y32. And pinning, either Pinned or Sub-Assembled. Finish is the sixth, with 13 to choose from. Get the key technology wrong and the cylinder will not accept the keys already on your system, so match it to whatever platform your existing Medeco cylinders run on.
3) Is the Medeco 100400H high security rated, or just a standard rim cylinder?
It is UL 437 listed for drill and pick resistance, and BHMA Grade 1, heavy duty commercial. That is the combination a spec writer usually means by high security: a verified attack rating plus the top BHMA grade. The M4 sidebar adds the mechanical side of it, the key has to be elevated, rotated, and aligned before the plug will turn, which is what defeats bumping and picking. For a facility standardizing on a documented security level, UL 437 is the line item that matters.
4) Can I master key a Medeco 100400 into a system I already have?
Yes, within the M4 platform. The 100400 can be masterkeyed into a system containing M4 BiLevel cylinders, and Bilevel is one of the key technologies you can order it in. The constraint is the key technology axis: Biaxial, Bilevel, KeyMark, M3, and Original are separate platforms, and a cylinder ordered on one will not operate keys cut for another. Order it in the same technology as the rest of your building and specify the existing key code.
5) Can my tenants get Medeco keys copied at a hardware store?
No, and that is the point of buying it. The 100400 uses Medeco's M4 utility-patented key control, which requires Medeco-specific key blanks and a special key cutting machine. A hardware store or a kiosk cannot duplicate the key. For a property manager or an MRO buyer, that is what stops keys walking out of a building and turning into unauthorized copies. It also means you order duplicates through the Medeco channel rather than cutting them yourself.
6) Do I have to replace my rim exit device to upgrade to a Medeco cylinder?
No. The 100400H is a 1-1/8 inch rim cylinder, the standard rim format, and M4 cylinders are made in a wide range of formats that retrofit most hardware in service today without changing the lock. On a rim exit device or a surface deadbolt you are pulling the existing cylinder, fitting the Medeco with the correct tailpiece orientation, and leaving the device on the door. That is the usual way a building steps up to patented key control one opening at a time.
7) I just need a dummy or thumbturn on the inside of the door, do I need a Medeco cylinder?
No, and paying for patented key control on an opening that is never keyed is wasted money. Where the inside of a rim device only needs a turn instead of a key, the Kaba Ilco 7011 is a 1-1/8 inch turnknob rim cylinder and the ADA 7011 is the thumbturn version in the same 1-1/8 inch size. Where the hole just needs filling with no operation at all, the Kaba Ilco 7010 is a 1-1/8 inch dummy rim cylinder. All three share the 1-1/8 inch rim format the Medeco 100400H uses. Save the Medeco for the keyed side.
8) What is a cheaper alternative to a Medeco rim cylinder for low security doors?
For openings that do not need patented key control, the Kaba Ilco 605 Series is a 5 pin replacement rim cylinder, sold by the 10 in satin brass. It is a straight replacement cylinder, not a high security one, so it carries none of the drill and pick resistance the UL 437 listed Medeco 100400H does and its keys can be duplicated on ordinary blanks. Use the Ilco on storage rooms, back-of-house and interior doors, and keep the Medeco on perimeter, cash-handling, and anything where key control matters. Note the pin count difference too: the Medeco is 6 pin, the 605 is 5 pin, so they do not share a keying system.
9) What is the difference between the Medeco 100400H rim cylinder and the Kaba Ilco 605 Series replacement rim cylinder?
Both are rim cylinders that mount behind an auxiliary rim lock, but they sit at different security levels. The Medeco 100400H is a 6-pin cylinder in brass, rated Grade 1 heavy duty for commercial use, and it is UL 437 listed for drill and pick resistance with patented M4 key control that requires Medeco blanks and a special cutting machine. The Kaba Ilco 605 Series is a 5-pin replacement rim cylinder in a satin brass finish, sold by 10s. Specify the Medeco when the opening needs restricted key control and attack resistance; the Ilco 605 Series is the choice when a plain replacement cylinder is what the door calls for and stocking a carton of them at once suits the job.
10) What rim cylinder should I use on an opening that needs a thumbturn instead of a key on the inside?
Use a turnknob rim cylinder rather than a keyed one. The Kaba Ilco 7011 is a 1 1/8 inch (28.6mm) turnknob rim cylinder, and the Kaba Ilco ADA 7011 is the 1 1/8 inch (28.6mm) thumbturn version. Both carry a turnknob function instead of a keyway, so the inside of the rim lock retracts by hand. The Medeco 100400H is a keyed 6-pin cylinder with a horizontal/vertical tailpiece and is the part for the keyed side of the same opening. A common pairing on a jimmyproof or surface deadbolt is the Medeco outside for key control and a turnknob cylinder inside.
11) Can a Kaba Ilco 7010 dummy rim cylinder be used in place of a Medeco 100400H?
No. The Kaba Ilco 7010 is a 1 1/8 inch (28.6mm) dummy rim cylinder, a dummy function part that fills the cylinder hole and gives the outside of the door the look of a cylinder without operating anything. The Medeco 100400H is a working 6-pin keyed rim cylinder, UL 437 listed for drill and pick resistance, that drives the rim lock through its horizontal/vertical tailpiece. They share the 1-1/8 inch rim format, which is why they look interchangeable, but a 7010 in a door that has to lock leaves the opening inoperable. Use the 7010 only where a cylinder prep was cut and no locking function is wanted.
12) I need to add key control across a building that currently has Ilco 605 Series rim cylinders. What do I move to?
Move the keyed openings to the Medeco 100400 rim cylinder. The Ilco 605 Series is a 5 pin replacement rim cylinder; the Medeco 100400H is a 6-pin brass Grade 1 heavy duty cylinder whose M4 design carries utility-patented key control, so duplicate keys require Medeco blanks and a Medeco cutting machine. It is UL 437 listed for drill and pick resistance and can be masterkeyed into a system containing M4 BiLevel cylinders, which is how a facility brings scattered openings under one hierarchy. It is offered in Biaxial, Bilevel, KeyMark, M3 and Original key technologies, so the cylinder can be matched to a key system already in place, and in finishes from 605 Bright Brass and 606 Satin Brass through 626 Satin Chrome to match existing trim.
13) What is the difference between ordering a Medeco rim cylinder Pinned and Sub-Assembled?
Pinned means the cylinder arrives with a working key combination in it. Sub-Assembled means it comes without the final pinning, so a locksmith with a Medeco pinning kit sets the combination on site or at the shop. If you run your own keying, sub-assembled lets you bring the 100400 into an existing system with your own bitting. If you want it to work out of the box, order it Pinned and specify Keyed Different, Keyed Alike, or to an existing Key Code.
14) Which Medeco 100400 finish matches the rest of my door hardware?
Thirteen finishes are available on the 100400 rim cylinder, so it can be matched to almost any existing package: 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. If you are matching commercial exit devices already on the building, 626 satin chrome and 613 oil-rubbed bronze are the two that show up most in the field. The cylinder body is brass underneath in every case.
15) Is a Medeco 100400 rim cylinder suitable for a high traffic commercial entrance?
Yes. Brass body, 6 pin, BHMA Grade 1 and rated heavy duty for commercial use. Grade 1 is the top BHMA grade and the one written into specs for schools, hospitals, government buildings, and multi-tenant residential entrances. Brass also holds up outdoors better than plated pot metal, which matters on a perimeter door that sees weather.
16) Is the Kaba Ilco ADA 7011 different from the standard 7011 rim cylinder?
They are two catalog items with the same turnknob function in the same 1 1/8 inch (28.6mm) rim format. The Kaba Ilco 7011 is described as a turnknob rim cylinder and the ADA 7011 as a thumbturn rim cylinder, the ADA designation identifying the version specified where the turn piece has to meet accessibility requirements for operation. If a facility is standardizing on ADA-compliant hardware, order the ADA 7011 by part number rather than assuming the plain 7011 will pass. Neither is keyed; for a keyed 6-pin cylinder on the same style of rim lock the Medeco 100400H is the part.
