ProVent™ Exhaust Hoods With J-Channels

Nut Driver Ready icon


Dundas Jafine ProVent™ exhaust hoods with j-channels feature a 3 louver damper system that helps to prevent cold air backdraft, snow or rain from entering the home. The louvers on the ProVent™ cap are cammed to allow for easy pivoting and to help prevent sticking.  Additional features include a recessed caulk line to assist in a clean caulking application and a snap on pipe to cap assembly that eliminates the need for lint trapping staples.

The j-channel that accompanies this product mounts onto the exterior wall prior to installation of the vinyl siding or stucco. It provides a secure, easy to install flush mount that channels away moisture from the substrate and the vent hole. It also allows for quick and easy cap replacement in the future.

All ProVent™ products have a UV resistant coating to prevent the cap from discoloring and are paintable to match the exterior of your home. This product is ideal for bathroom fan venting, dryer venting and kitchen range hood venting.
