Portable Pipe Hangers was created out of a growing need for a dependable, cost-effective means to support roof-mounted items without the need to penetrate the roof system. This system can be used for hanging piping, ducts, conduits, and cables, as well as for access walkways and HVAC, process, and telecommunications equipment platforms. The system can be used on virtually any roofing system, from flat roofs to roofs sloped up to 2 in 12. A new 18 inch diameter round base can be mechanically fastened, for those applications requiring anchorage.
