DuraVent DirectVent Pro Vinyl Siding Standoff: a flat seat for a square wall cap
The DuraVent DirectVent Pro Vinyl Siding Standoff is a one piece spacer for the square cap at the outside end of a vent through the wall. It holds the hot cap away from vinyl siding to help keep the siding from warping or melting. It also gives the cap a flat place to sit on uneven lap or shake siding. This part is for horizontal vents only, not roof exits. 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. The cap attaches to the standoff with the long screws supplied in the cap’s box, and the standoff is sealed around its edge. For a stucco wall, counter flashing serves the same purpose and lets the stucco finish meet its edge. Prefer a four piece version? See the DuraVent DirectVent Pro Vinyl Siding Standoff Kit.
