It is M12 threaded at both ends, thus it could be extended with a M12 threaded rod via a rod connector. It only costs $11. It is really worthwhile!
These are simple, of course, but up to the awesome build quality I've come to expect from SmallRig. They're threaded at each end and very solid. Not much to say but would highly recommend.
