his all inclusive all metal hook up kit is truly the ultimate installation kit for both the contractor and consumer.
This kit includes:
– One 4″ x 8′ UL 2158A listed and marked semi-rigid aluminum duct
– Two attached all metal heavy duty elbows
– Two 4″ metal galvanized worm gear clamps
The semi-rigid duct is UL 2158A labeled and approved for safe dryer venting. This duct not only meets but exceeds all dryer manufacturers instructions and requirements. It is 35% thicker than our standard non UL duct and like all aluminum ducts is totally noncombustible. New manufacturing technologies incorpoated into this duct also allow for easy rotation, therefore adding durability during installation.
The two metal elbows are flame resistant for a safe and long lasting connection. They are designed to achieve tight 0 to 90 degree turns which saves space while still maximizing airflow and are crush resistant.
