Rooftop device for delivering electrical power, plumbing, lines and other systems from the inside of a building to the outside of the building to equipment and systems installed on the rooftop. The device comprises a powder coated white NEMA 4 enclosure to reduce corrosion and minimize the effects of heat buildup in the enclosures during high temperature exposure. A GFCI circuit breaker in the enclosures allows electricians to move electrical power from the closes source, which reduces installation costs. The device comprises MCB or MCP disconnect switches which will provide faster and more precise protection to equipment and the circuits that supply them, and ethernet cable, coaxial cable, conductor thermostat wire. A mounting assembly, comprising a flashing and a cleat, and a vice assembly cooperate to apply pressure from the outside of the rooftop and from the inside of the roof, providing a more secure, dryer fit for roof penetrations.
