Frost Shield™ Duct Rings are designed to make connecting 4” round metal duct pipe faster, easier, and more consistent.
These rings slide onto the end of the duct pipe to help keep the pipe from bending or warping during installation while also helping keep the seams lined up closely for easier assembly.
Ideal for bathroom exhaust vents, dryer vent pipe, HVAC ventilation, and general sheet metal ductwork, Frost Shield Duct Rings help simplify duct assembly and improve alignment during installation.
Designed by an HVAC technician for real-world use, these rings are lightweight, reusable, and easy to spot on the jobsite with their bright blue color.
