#1 Q:   Does the duct end get screwed in (self tapping screws), or is it a zip tie/tape wrap?I have a tin collar that would fit over each side and wonder if this will work. The securing it so it doesnt slip out is whats confusing me
A:   Would depend on type of duct. Metal would be slid over and screwed to the collar and flex would use zip ties most often. Tape the connection after.
