My old cable vent, badly deteriorated. It was recycled from an old barn when I remodeled my cottage 2002-2004.
I am thrilled with my new sliding window with screen. It's really a double hung window put in sideways. It's open in this picture. The black side is the screen and the reflective glass is on the right side. I love looking out from the third floor. I have the weekend off to recover from a whirlwind week. Whew.
