ENSER Corp worked with Tom Scannel to re-design the concept and build the prototypes. He realized there was a great potential for the product to prevent incidents involving the alteration of safety cables. Once the cable vault covers the safety cable and clamps, it is locked and cannot be removed without a key.

The FLEXO Film Machine design decisions were made based on common engineering and design experiences; only key elements were analyzed using FEA. The solution was to evaluate one core structure at its worst condition and redesign it accordingly to suit both the smaller and larger machines.
