Medeco 11-0A21-20 – Frequently Asked Questions

1) Will the Medeco 11-0A21-20 thumbturn work with any Medeco cylinder, or only M3?
It's built for the Medeco M3 Captive Blade system only. The thumbturn is machined for that platform's blade arrangement, so it is the part to order when you're servicing an existing M3 Captive Blade installation. Pair it with a different Medeco generation and you should not assume it mates.
2) Is this a complete lock or just the thumbturn piece?
Just the inside thumbturn. The 11-0A21-20 is a replacement component for an M3 Captive Blade lock, not a cylinder, not a deadbolt body, and no key cylinder is included. If the cylinder itself is worn or you're rekeying, that's a separate order.
3) What finish does the Medeco 11-0A21-20 thumbturn come in?
One finish only: 620 Antique Nickel. If you are matching a fleet of doors already trimmed in bright brass, satin chrome or oil-rubbed bronze, this is not the finish code to order, so check the 620 designation against the existing trim before you commit to it across an opening.
4) It's called a residential style thumbturn. Can I use it in a commercial building?
Yes. "Residential style" describes the shape of the turn piece, the comfortable knurled profile a hand grips, not the grade of the application. Medeco classes the part as commercial, and it's used in offices, multi-tenant residential, healthcare, schools and municipal buildings running M3 hardware.
5) Do I need a genuine Medeco thumbturn, or will a generic turn piece do?
For an M3 Captive Blade lock, order the Medeco part. The captive blade design is proprietary to Medeco's high-security platform, and the 11-0A21-20 is the factory component made to engage it. A generic turn piece is not cut for that interface.
6) I'm standardizing thumbturns across a building with Medeco M3 deadbolts. Is this the part to spec?
If those deadbolts are M3 Captive Blade and you want antique nickel trim, yes, the 11-0A21-20 is the thumbturn to write into the spec. It only comes in 620 Antique Nickel, so standardizing on it means standardizing on that finish for every opening you touch.
