#1 Q:   Does this fit the Dayus DARH-FG filter grills?
A:   If ordered at the same time, easily. If they are not expecting it, sometimes it can be difficult as the undercuts are similar.

#2 Q:   how is the round duct attached to the rectangular? how is the box made: rivets, screws, welds?
A:   The DSSR is put together with rivets and it has a spin on collar for the round to square connection.
