A shutter tilt rod is the mechanism used in a shutter panel for opening and closing the louvres.
It’s either visible on the front of the shutter or hidden to the back of the panel.
A split tilt rod is generally associated with the hidden tilt rod. Instead of one rod connecting all of the louvres together, the rod is split, at whatever point you wish, allowing a section of louvres to open and close independently of the remaining louvres.
