Iconic Theme Park Flies MCG Protectors to Site

At the height of summer fun (and thundershowers), thirty MCG Data Line Protectors - DLP-20G's - hopped a plane to protect sensitive data lines at an iconic theme park. Amusement park enthusiasts were blissfully unaware that their vacation getaways went without a hitch with a little help from these MCG workhorses.

Testimonial

"In a time of extreme danger and risk, two Model 415 AC Power Line Protectors gave the ultimate sacrifice in service to our nation. Being bolted in place with power lines installed these stalwart warriors held their line until overwhelming numbers of volts and amperes defeated their positions. In doing so, these warriors provided the necessary protection for the survival of all associated soldiers down the equipment line. Bravo Zulu."
