Default straps for flex duct
Is the requirement just that the strapping being a min 12 guage? If so I thought the shoe strings holding this up would work just fine.

Default Re: straps for flex duct
1.5" is the minimum width for straps, gauge is not so important. Generally at 4' max intervals, some manufacturers allow up to 5' intervals.
