The folded strakes (surprisingly rigid!, no bufeting whatsoever) reside in aluminium C channels glued in with gorilla glue. Gorilla glue makes for an extremely rigid bond.
The C channels are attached to the diffuser with nuts & bolts. Compared to the wooden prototype, the coroplast version weighs half as much, 4lbs!!!
