[Clamp] Aputure Lightning Clamp to Ultra Clamp Adapter Kit
The Aputure Lightning Clamp to Ultra Clamp Adapter Kit retrofits a control box fitted with a Lightning mounting plate so it can mount to the newer Aputure Ultra mounting structure. Used with the Aputure Ultra Clamp included in the kit, it brings older control boxes up to the same rapid install and removal as current fixtures, and it significantly improves the stability and long-term reliability of the quick-mount system.

With the Adapter Plate installed, the control box mounts to the Aputure Ultra Clamp.
