Easy to use and install. Used the collar to connect a Range Hood to an existing old valve (the hood opening is wider than the valve). MacGyvered a secure connect with some duct tape and it works like a charm.

Product was well made, and installed easily. Made of heavy enough gage metal it didn’t bend. Crimped enough I didn’t have to force it into the other 6” pipe that it was hooked to. Would recommend

I bought this for a project I was fabricating. It was only used to run a 3" dia. HVAC pipe through and worked perfectly for my needs.

Heavier gauge than aluminum parts. Therefore when to drilled and take, it holds significant weight.

This is the best 4” starting collar I have ever seen. It really made the project. I have never seen a better one in my 30yrs and would definitely recommend.
