We recently added a garage AC and the way the coolant lines needed to run, they come out of the wall on my back patio and then go into the ceiling. I'd like to hide this, not only for looks but also to protect the lines. I would like the solution to be enclosed- not a tube type of covering. There is a cute lil wire hider elsewhere on my patio- but its about 4 inches whereas my AC lines are nearly 2 feet long. I'm thinking something like this.

Anyway, is there a solution besides building a custom wood covering?
