The Builder’s Best SilverDuct Wire Helix Aluminum Foil Hose is a UL 2158A–listed transition duct designed for connecting clothes dryers to vent outlets in short, direct installations. The flexible duct provides a secure and efficient path for air exhaust while meeting recognized safety and performance standards for residential laundry systems.
Constructed with a multi-ply foil design, SilverDuct combines layers of aluminum, polyester laminate, and metalized polyester for strength, flexibility, and resistance to tearing during installation. The duct’s steel wire helix support maintains shape, prevents kinks, and allows smooth alignment when connecting the dryer to the wall or ceiling outlet.
This model includes 2 plastic clamps for secure attachment to the dryer and wall vent connections. It ships compressed for easy packaging and handling, expanding to its full usable length during setup. SilverDuct is UL 2158A listed and labeled as a foil dryer transition duct and is approved for installations up to 8 feet in length.
Builder’s Best notes that foil ducts may crush easily and contribute to lint buildup if installed incorrectly. Users should follow dryer manufacturer instructions and local building codes to ensure safe installation and operation.
