90 degree Close Wall Elbow Dryer Vent Duct - Standard, 90-degree,

Elongated 90 degree, Close Wall Elbow (Dryer Outlet) -


the one in the first link is fine, but the one in the second link is a fire
hazard.

the whole point of correct dryer venting is no restrictions, and that second
one temporarily cuts the pipe in half, which is a MAJOR restriction, and
will collect lint and greatly increase back pressure etc.

I agree with the guy that said to get a new wife!
