AC Infinity Stainless Steel Duct Clamps – 2-Pack, 4" to 12"

AC Infinity Stainless Steel Duct Clamps – The Cheapest Upgrade in Your Tent

Most leaks in an extraction system are not in the fan or the filter. They are at the joins, held by a twisted cable tie or a strip of tape that gave up last summer. A leaking join means your fan works harder, your filter is bypassed and smell escapes. A proper worm-drive clamp costs less than a takeaway coffee.

• Stainless steel worm-drive clamps that won't rust in humid spaces
• Tighten by screwdriver or hand for a firm, airtight seal
• Sized for AC Infinity and all standard ducting, 2 per pack

🌿 Rose's Pro-Tip: clamp over the duct and the fan or filter flange together, then give it a gentle pull. If the duct moves, it isn't tight enough.

Pairs well with: four-layer ducting, Cloudline EC inline fans, carbon filters.
