If you’re trying to put together a DIY rig this adjustable friction arm set might be something handy. It’s a . $30 a peace is a pretty good deal, but what’s the catch? Well the catch is that one side is 1/4, but the other side is 5/16.

With those sizes this probably wont be handy for everyone but it might be great if you’re building a Rig from scratch.
