The Dundas Jafine J-Channel mounts on the exterior wall prior to installation of the vinyl siding or stucco. This product provides a channel to which vents can be attached to for a more seamless appearance, without the use of screws or caulking.

The J-Channel provides a secure, easy to install flush mount for the exterior wall caps and allows for quick and easily replacement of the cap in the future. It helps to channel away moisture from the substrate and venting hole and can be used in conjunction with Dundas Jafine ProVent™, ProGard™, EzAccess and ProShield™ caps and hoods.
