When subjected to the instant mechanical whiplash of the opener motor and external aerodynamic lift, thin components undergo micro-buckling and macro-slip, losing their hermetic seal. Upgrading to a heavy-duty carbon steel assembly with precision CNC-machined adjustment slots neutralizes these intense dynamic forces and permanently locks out harsh environments.
