The Concrete Port Cover (for termite baiting) has a brushed aluminum finish that is smooth on the top when the cover is installed (this photo is really upside down). The station can be tightened and loosened using an allen wrench in a screw in the center (connected to the red piece) to secure the cover and to lock out moisture. This cover is designed to fit into 3 inch holes perfectly for a smooth, flush covering. After you loosen the cover, you can use a flathead screw driver to help lift it out of the station.
