Rock-Vent Wall Pass-Thru

The Wall Pass-Thru Non-Insulated Thimble is used when a Class A chimney passes horizontally thru a combustible wall. Adjustable from 4" to 8". A universal adapter is included to seamlessly transition the Rock-Vent Class A chimney pipe to either single or double wall stove pipe. The Universal Adapter has a female end to accept the Rock-Vent Class A pipe and transitions to a male end to fit into single wall or double wall stove pipe. The Wall Pass-Thru also includes a 10" length Finishing Cover to go over the Class A pipe on the interior. Exterior is satin coat black steel "paint ready" to match the home exterior. Note: The chimney must penetrate through the wall a minimum of 6" into the interior. We offer optional accessories such as the 12" length extension, 430 Steel Cover Plate, and the Siding Trim Kit. The Siding Trim Kit is needed if you have exterior vinyl or aluminum siding. It is recommended to seal the outside edge of the firestop section of the Wall Pass-Thru with waterproof exterior silicone.
