What you need to provide:
Eight pieces of 4 inch solid corrugated tubing 20 feet long.
If you must buy a coiled roll of corrugated tubing; buy a 200 foot roll and cut into 25 foot pieces. For best results if you buy rolled corrugated tubing, cut tubing a couple of days before you start installation. Leave tubing inside to help straighten tubes (the straighter the tubes, the better the airflow).
