The pack includes 2pcs of 15mm rods. When you see it, it looks very shining. When you touch it, it feels very sturdy. After it was delivered to me, I instantly tried it on 15mm rail support system. It fits my 15mm rod clamps completely! The rod could be connected via a M12 threaded rod. A GREAT purchase for me!
