Great news! While QuadLock uses their own proprietary case system with a 22mm ball standard, they've recently released an adapter that bridges the gap between QuadLock mounts and standard 20mm ball systems.

Here's how to make it work:

Step 1: Get the QuadLock Ball Top Cap Adapter in 20mm
You can find it here: https://www.quadlockcase.com/collections/whats-new/products/ball-top-cap-adaptors
(Make sure to select the 20mm ball size option)

Step 2: Connect it to any 67 Designs Clamp2Clamp Pro Series Arm
Check out their options here: https://www.67d.com/products/arm-builder-pro-series-arms

This combination gives you the flexibility to use your QuadLock case with the more versatile 67 Designs mounting system. It's a simple solution that opens up a lot more mounting possibilities!

Let me know if you have any questions about compatibility or installation!
