Due to its superior flexibility and increased BTU capacity, our smooth wall liner is gaining in popularity. Its smooth interior design allows for more airflow, adding back the 20% drag factor that's lost in traditional corrugated liners. And since it's made of 2-ply 316 stainless steel (.013 total thickness), it's great for any application. You can use it with all of our round liner components.
