Overview
An undereave vent cap for exhausting a clothes dryer or bathroom fan without cutting through roofing, sized 7 inches wide by 10-1/8 inches long with a 4-13/16 inch duct connection and built-in dampers.
It's meant to mount flat against a soffit rather than a wall or roof, which lets installers skip drilling through shingles, but several reviewers found the flapper hinges bind if the soffit surface isn't perfectly flat, sometimes needing shims or trimmed flaps to open and close properly. Fasteners aren't specified for you, so plan on matching screws to whatever material you're mounting into, whether wood, plaster, or drywall soffit.
- 7 in W x 10-1/8 in L x 2-1/4 in H
- 4-13/16 inch duct connection
- Polypropylene construction, white finish
- Built-in dampers for cold air blockage
Who it's for
Fits homeowners and builders venting a dryer or bathroom fan out through the underside of a roof overhang instead of a wall or roof penetration. Less suited to anyone with an uneven or non-flat soffit who isn't prepared to shim or trim the unit to get the dampers moving freely.
What buyers say
From Amazon customer reviews.
Buyers who install these on flat, even soffit report the built-in damper works well to keep cold air out, and the vent stays out of sight. Others describe the flapper hinges binding open or closed on uneven mounting surfaces, requiring trimmed flaps or added spacers to get a working install.

- Mounts under the eave, avoiding a roof penetration
