Eliminate Solar Rack Ballast and Reduce Rooftop Material Handling. PowerGrip™ Universal (PGU) is a commercial roof mount system designed to secure solar racks and other equipment to any type of commercial roofing system. PGU provides a secure connection directly to the roof deck or structural members and is designed to reduce or eliminate ballast in solar racking systems, so there's less weight on the roof and less material handling. Made of heavy-duty cast aluminum, PGU units include a base ring which is secured through the roofing cover and into the structural roof deck, and a waterproof top plate.
