摘要

A clip-on retrofit drainage tray or trough is disclosed. The device has a full width tray fitting at the exposed back edge of a window unit or through-the-wall air conditioner, and is located just below the bottom of the sleeve to catch condensate. The dripping water is drained into the trough and out through a drain hole formed in the trough. The trough has an overhead clip attaching on a lip above the sleeve bottom.
