Description

An 8" x 25' run of R4 insulated flexible duct. Eight inches is the middle size — bigger than a single register connection, smaller than a trunk — so it typically serves a branch feeding a couple of outlets. R4 insulation suits runs inside conditioned space; use R6 where the duct passes through an attic, crawl space or garage.
