Astronics / EADS / Racal 404836 Single-Slot B/C-Size Blank Filler Panel Kit

The Astronics / EADS / Racal 404836 is a single-slot blank filler panel engineered to occupy empty B/C-size slots in VXI mainframes. It prevents dust and foreign object ingress while maintaining proper airflow distribution and thermal management across populated modules. Secured with two captive mounting screws, this blanking panel protects sensitive internal components and optimizes cooling performance by directing airflow through active slots and eliminating uncontrolled bypass paths.
