Hide-A-Line Ductless (mini-split) line cover set. I bought an extra set and did not need all of the components. There is NOT a 90-degree section in this kit, and the length is about 12 feet. Kit includes the top wall cover (where your air handler components come thru the wall), three couplers, an end cap and three sections of line covers (there is an extra number of pre-cut and painted line covers that you may need, also included). The 1st picture is what the line covers look like once installed. located in Cocolalla.
