M&G DuraVent 7" DuraTech Wall Thimble - 9543 // 7DT-WT

About the M&G DuraVent 9543

Improve chimney venting safety by incorporating this wall thimble!

The DuraVent 7DT-WT wall thimble is an essential part of chimney venting systems because it creates a safe, insulated passageway for vent pipes to pass through combustible walls or ceilings. Its primary function is to provide a fire-resistant barrier that restricts the flow of heat.

This wall thimble accommodates different wall thicknesses with adjustable sizing from a minimum of 5-1/2-inch to a maximum of 9-1/2-inch. In addition, to increase the thickness of the walls, it is possible to extend the telescoping pieces up to 16 inches through the use of a field-fabricated extension. Also, it conveniently fits between standard wall studs. For a correct installation, it is necessary to position the DuraTech chimney pipe horizontally through the wall, extending 6-inch beyond the interior wall and into the room.

DuraVent is a go-to brand in the HVAC and Hearth industries for its wide variety of top-notch and expertly-engineered venting solutions.
