Medeco 208008T-26-DLT – Frequently Asked Questions

1) Will a Medeco 208008 cylinder fit an Arrow M Series knob lockset?
That's exactly what the 208008 is built for. It's a key-in-knob cylinder with the tailpiece configuration cut for Arrow M Series knobs, so it drops into the existing knob without swapping the lockset. If your knobs are a different Arrow series or another manufacturer, you need a different tailpiece configuration, not this one.
2) Can I retrofit a Medeco high security cylinder into my existing knobs without replacing the whole lockset?
Yes, and that's the point of the 208008. It retrofits knob-type cylindrical locksets, lever-type cylindrical locksets, padlocks, and bored-type auxiliary deadlatches and deadlocks. You keep the lockset, the door prep, and the trim, and only the cylinder changes. Medeco builds over 100 cylinder and tailpiece configurations for this reason, so the 208008 is the Arrow M Series member of that range.
3) Do I order the Medeco 208008 in Biaxial or M3 keyway?
Both are offered, and the deciding factor is the key system you already run. If your facility is keyed on Medeco Biaxial, order Biaxial so the new cylinder takes your existing keys and fits your master key schedule. If you're on M3, order M3. Mixing platforms in one building means two key systems to manage, so match what's already in the other doors rather than picking on the cylinder alone.
4) What is the difference between Pinned, Sub-Assembled, and Sub-Assembled No Slider on a Medeco key-in-knob cylinder?
It's how much of the work is done before the cylinder reaches you. Pinned arrives built to your key system and ready to install. Sub-Assembled comes as a cylinder a locksmith pins to their own system, which is what a shop running its own Medeco key records wants. Sub-Assembled, No Slider leaves the slider out for shops that install their own. Property managers and MRO buyers with no pinning capability in house should take Pinned.
5) Is the Medeco 208008 UL437 listed for drill and pick resistance?
On the M4 platform, yes, UL 437 listed for drill and pick resistance, and certified to ANSI A156.30 Level A and ANSI A156.5 Grade 1. Grade 1 is the heavy commercial duty level, so this holds up on high traffic openings in schools, healthcare, and government buildings. For a spec that calls out UL 437 by name on the drawing, this cylinder answers it.
6) Is the Medeco 208008 a 5-pin or 6-pin cylinder?
Six pins. That's a deeper pinning stack than a 5-pin, which matters when you're building a master key system with enough change keys to cover a large building or a multi-tenant property. If your existing Medeco system is pinned at 6, this keys straight into it.
7) Can I get Medeco cylinders in a finish that matches the knobs already on my doors?
Thirteen finishes are offered on the 208008: 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. Most commercial buildings run 626 or 613, so check the number stamped on your existing trim and order the same code.
8) Does a Medeco cylinder stop keys from being copied at the hardware store?
The 208008 uses utility patent-pending key control technology that restricts unauthorized duplication, so blanks aren't available over the counter. For a property manager handing keys to contractors and tenants, or a facility tracking who holds what, that's the practical difference between this and a standard key-in-knob cylinder. ANSI A156.30 Level A is the certification that covers that key control along with physical strength.
9) What is the Medeco 208008 made of, and will it hold up in a high traffic building?
All components are machined brass, and the cylinder carries ANSI A156.5 Grade 1, the heavy use commercial rating. It's classed as commercial hardware, not residential, and is used in office buildings, schools, healthcare, retail, government facilities, multi-tenant residential, and warehouses.
