DuraVent DirectVent Pro Universal Wall Thimble: a wall sleeve with no outside trim
The DuraVent DirectVent Pro Universal Wall Thimble is an adjustable sleeve that carries vent pipe through an outside wall. It installs from indoors and leaves no thimble plate showing outside. The sleeve adjusts to meet the back of the cap, letting any DirectVent Pro cap, including a snorkel, sit flat against the siding. It includes an interior firestop that closes the opening on the room side. DirectVent Pro is DuraVent’s pipe inside a pipe vent for direct vent gas fireplaces and stoves: exhaust goes out through the inner pipe and outside air comes in through the outer pipe.
Choose the 4 by 6 5/8 inch or 5 by 8 inch size to match your vent. For wood framed walls, the appliance maker may call for a thimble or wall firestop to protect the framing. Canada requires a two piece wall thimble. Brick, block, or concrete walls can have a hole without clearance around the pipe if the appliance maker allows it. Need the standard two piece version? See the DuraVent DirectVent Pro Wall Thimble. The DuraVent DirectVent Pro Universal Wall Thimble ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
