Do both sides of this have flanges for house connection?

Yes it has the flange on both sides. Due to the picture I assumed it was only one sided as I needed, and had to cut off the other side for use.

What are the dimensions? Size of square part & how long is the tube part.

Flange of the 4” connector is 5-7/8” square
