Master Flash®

  • Engineered for profiled metal roofs
  • The base is designed to form a seal on any metal panel configuration and roof pitch
  • Cut opening 20% smaller than the pipe outside diameter (OD) to get a
    compression seal.
  • Compounded specifically for maximum resistance to weathering due to ozone
    and ultraviolet light
  • Master Flash is easily customized with a sharp knife
  • EPDM/SILICONE
