Hi All,

I have about 9 feet of pre-wrapped flex liner left from a previous install but need about 14 feet for a second unit. Recommendations for resolving the 5ft difference?

I have some rigid steel pieces from Lowe’s that I was thinking I could connect but not sure the best approach.

Get more liner and the proper coupler to join them together
 
This is what I have used in the past for flex liners, you will need to check to see what works best with your liner since it is pre-wrapped.
