Review on 🔧 Adjustable Aluminum Alloy Tabletop Light Stand Clip with 1/4inch Screw for Ring Light and LED Light - Ideal for Make Up, Live Streaming, Photo Video Shooting - 12.5-20.6 inches/32-52cm by Vincent Bain

Bottom clamp is for clamping the edge of a flat table. For a long time. Most tables are no longer separate areas as they used to be. In my case the table frame is below; there is no single point of a simply flat table except at the left and right edges; even then it is only an inch wide. It's not enough for that. I tried clamping the frame bar but since the clamp is straight C it wobbles because the adjustment screw is too thin. This basically assumes that the surfaces are perfect everywhere; So unless you secured it with some kind of wood or something else (which I didn't mean to do), this might not work for you. The best I could do was clip into the cable routing holes, which worked but not exactly what I wanted. A design change for this would be to make a metal top with an adjustable bottom instead of a metal C with an adjustable screw. It can therefore be used in a variety of ways for "complex" tables and desks.
