This is a Part of my Ecosystem - Audio / Video Filming Cart. More specific, these are adapters, with holes for 1/4 Threaded Inserts, for mounting them to Aluminium Profiles 3030 (T-Slot or V-slot). Is for mounting different types of Camera Gear, into with 1/4 Threads (very common for Camera Gear). For mounting them on the Aluminium Profiles, you need 2 x M6x60mm Hex Screws and 2 x M6 Profile Nuts for the Grove of your Aluminium Profile (typically 8mm groove).
You can see how I installed it in 😎 👉 my Filming Cart Video here (more detailed video coming soon)
In this example, the entire System is mounted onto an IKEA Alex Cabinet. It can be mounted on any other cabinet (I recommend a heavy one, to have more stability)
