Abstract:
A fenestration unit includes an outer frame portion, an inner frame portion and a supplemental fixation system that secures the outer frame portion to the inner frame portion. The supplemental fixation system increases a base force required to flex and release a complementary fit between a coupling feature of the outer frame portion and a retaining feature of the inner frame portion to a final force required to decouple the first and second frame portions.
