I seem to buy 10 accessories every two weeks, things change, rigs change, drives change, life changes. The need for a well-built, unique track block and track accessories is irrelevant. I use this as the base for the matte box, swing arm and the part on the 15mm side rail. Full in the cinema. It's 100% and I'm not talking about threats over many accessories. I pull off 1/4/20 threads on the fly, clog the gear I use because I do it every day. This hold is available in 3/8 and 1/4 20 sizes and the hand screw is great AAA!
