CONNECTOR 1-3/4"x3"x1-3/4" VINYL DUCTMATE
Vibration-dampening duct connector rolls join two metal ducts while reducing vibration transmission along the duct run. They include two metal strips connected with a flexible, airtight fabric section between them. The metal strips provide a solid connection point for the ducts while the fabric section muffles sound and vibration transfer between them. They are commonly installed onto the outlets of air handlers and fans to reduce noise in the occupied space.
