BO Scoop (Carbon V1) was inspired when I purchased one of the alternative Vent Scoops on the market that advertised to fit my bonanza.  Unit was considerable undersized for my window and required adhesive on my window which would have been problematic for my window tint.  
OVERSTOCK UNITS COME WITH FLEXSEAL COATING!

Ordering Considerations
In my research there are several size window vent openings available, as well as two primary thickness of glass being 1/4” and 3/8”.  Upon ordering you will be required to specify height of opening and glass thickness.  This is necessary so that you’re custom BO VENT will maximize the space available and ensure clip has the proper friction.
Only color options available at this time is Carbon Fiber Gray.
"Flex Seal Coating" option adds added protection against plexyglass.
