Rockford's double wall chimney pipe has a limited lifetime warranty. It is manufactured with a 24 gauge black steel outer pipe and a .015", 430 alloy stainless inner liner. The double wall construction keeps the outside cooler and thus allows you to reduce both wall and ceiling clearances.
This adapter makes for an easy transition with no hole drilling required. Use when connecting Rock-Vent double wall black pipe to Rock-Vent Class A universal adapter.
