Enervex 222.0400.4012 ASCA steel chimney adaptor provides support for installing an RS or RSHT chimney fan on a round, air-cooled steel chimney. The adaptor mounts at the chimney termination point and combines a square mounting plate to support the fan with a round collar that slides into the chimney for a tight fit. The collar outer diameter is 1/8" (3 mm) less than the chimney inner diameter; the 5" collar design eliminates the need for external fastening. Construction is stainless steel 316L and it fits standard chimney sizes from 4" to 13" (150 mm to 325 mm).
