Does it open a full 90º?

I think the answer is, "close enough". I did check mine before installing it. If it wasn't 90 degrees, it was close enough. I don't think being off a few degrees from fully open would noticeably impede the airflow, anyway.

In a 12" what is the length measure ? Tks

It is specified as 8" on their cut sheet.

Hi, how tight of a seal does the damper make inside the duct? Thanks.

It has a gasket so the blade is sealed when closed. I’m using it on a fresh air intake from the exterior into my return air of my furnace and it seems to seal well that I’ve found.
