Lambro 284l Worm Gear Clamp, Galvanized Steel, 4 In.

The Lambro 284L is a galvanized steel worm gear clamp designed to secure flexible, rigid, and semi-rigid ducts in heating, cooling, and ventilation applications. This clamp is ideal for dryer vents, bath fan exhausts, and other ductwork installations where a reliable, leak-free connection is essential. The zinc-plated steel construction provides strength and corrosion resistance for both indoor and outdoor use.
