It includes a 4-inch by 8-foot flexible aluminum transition duct that is UL 2158A listed for safe operation.

Additionally, it features a removable pest screen to keep critters out while allowing for easy lint cleaning. The "snap-on" pipe-to-cap assembly simplifies installation by eliminating the need for lint-trapping staples.
