NIBCO introduces its PVC termination vent screens (#4818-SCRN) for high-efficiency appliance lines in residential construction. The new vent screens prevent wildlife, leaves and debris from blocking PVC exhaust vent pipes. Available in 2", 3" and 4" diameter sizes, the vent screens are easy to install by push or interference fit with PVC or ABS sockets. No solvent cement or glue is required for installation. The vent features a stainless-steel screen with1/4" mesh opening that is corrosion resistant and allows for maximum air flow. The interference fit makes it easy to install and easy to remove during freezing temperatures when condensation could freeze the opening shut, NIBCO noted.
