AC Infinity 8-Inch Stainless Steel Duct Clamps, 2-Pack

The AC Infinity AC-DCA8-2 includes two durable clamps made from SAE Grade 316 stainless steel. Their rust-resistant construction is well suited to humid grow tents, HVAC systems and workshop extraction setups.

Each clamp uses a precision worm-drive mechanism for smooth tightening and reliable holding power. The dual-drive screw head accepts both Phillips and flat-head screwdrivers, making installation and adjustment straightforward while helping create a secure, airtight connection.
