The kit features sliding panels that accommodate horizontal/vertical sliding windows from 16.5 to 47 inches and includes a louvered outdoor vent cover to block external elements while allowing airflow. It also comes with an adapter for 3" or 4" hoses, aluminum tape for insulation, a clamp, and self-adhesive foam sealing tape.
