Primex SV Series Low Profile Soffit Vents
The Primex Soffit Vent Series (SV Series) consists of low-profile, durable exhaust solutions for a range of applications. The UV-stabilized, one-piece design eliminates leaky seams. A one-way damper prevents rodents and debris from entering the home while effectively exhausting moisture. The SV Series offers three models for standard 4, 5 or 6-inch ducting and an aesthetically-pleasing termination.
