AC Infinity 6" Ducting Take-Off Collar, Galvanized Steel Inlet Flange Starter Collar for 6” Ducting with Dryers and Range Hoods

Excellent product, rigid nicely, put together worth every penny

I needed to attach a 4" hose to a piece of wood I put in a window to vent smoke from my CNC laser. This worked perfectly for that - it is VERY sturdy. The flange is pre-drilled so all you have to do is mount it and run screws in.

Way to perfect for what is meant to do. The way it's made,you can run water connections instead of air and will not leak.

Well built and comes with pre-installed adhesive foam gasket to adhere and seal flange. Flange also has 3 predrilled holes to tightly secure take off to surface. Easy to install. Protective film on adhesive foam gasket peeled off with no issues and gasket stuck with no issues. My 4 inch flexible duct from my bath fans tied into this perfectly!

Decent product, you could find one maybe 5 buck cheaper but it won't be as nice and it definitely won't have the adhesive gasket. Typically decent AC Infinity product.

The duct take off is well made, looks good, and was sold with great customer service. Unfortunately it doesn't fit for my application, which is to connect to normal 4" metal ducting. It is probably _great_ for flex ducting. The product description should do a better job of saying what this does and does not fit.Amazon sold this with a 'customers also bought' a standard 4" metal elbow, so I figure lots of people make this mistake.Customer service saved things with a fast refund, so I would buy from this manufacturer with no qualms.

I've been upgrading a Harbor Freight dust collector. Added a bigger impeller and installed this larger duct. About blew my shop away. This is a very fine product, heavier than anything at HD. A bit expensive but highly recommended.

Very nice take off that appears to be able to handle either 5" or 6" ducting with a bit of crimping or duct tape.

Absolutely great quality product and quick delivery
