AC Infinity 6-Inch Stainless Steel Duct Clamps, 2-Pack

Premium 6-inch stainless steel duct clamps for creating strong, airtight connections between ducting and ventilation components. Supplied as a 2-pack.

The AC Infinity AC-DCA6-2 is a pair of heavy-duty duct clamps made from marine-grade SAE Grade 316 stainless steel. A rust-resistant gloss finish helps protect against moisture, oxidation and corrosion in humid grow rooms and HVAC environments.

Each clamp uses a precision worm-drive locking system for smooth, secure tightening. The dual-drive screw head accepts both Phillips and flat-head screwdrivers, making installation straightforward across 6-inch flexible ducting, fans, filters and backdraft dampers.
