4 Inch Duct Connector Flange, ABS Dryer Vent Wall Plate for HVAC 4 Pack

• HECK SIZE BEFORE ORDERING: Designed for nominal 4-inch flexible ducting. The collar measures 3.8 inches in outside diameter, the flange measures 5.5 inches, and the overall height is 2.4 inches. Measure your duct’s inside diameter before purchase.
• STRAIGHT DUCT CONNECTION: The round collar creates a clean pass-through point for connecting flexible ducting through a wall, ceiling, window panel, cabinet, or equipment panel while helping give the opening a finished appearance.
• MOLDED ABS CONSTRUCTION: Lightweight one-piece ABS construction provides a smooth interior and clean black finish for general air intake and exhaust projects. Keep away from open flames, direct heat, and high-temperature exhaust.
• PRE-DRILLED MOUNTING FLANGE: 4 mounting holes simplify positioning on a compatible flat surface. Secure it with fasteners suited to the mounting material, then attach the duct with a compatible clamp or HVAC foil tape. Hardware is not included.
• FOUR-PIECE SET: Includes four black duct connector flanges for conveyor drum dryers, room-to-room ventilation, bathroom or kitchen exhaust, inline fans, portable AC window panels, hydroponic, range hoods, grow tents, workshops, and similar low-temperature ventilation projects.
