Abstract: A flashing system for use with an electrical service panel is described. The flashing system includes a flashing assembly extending about a perimeter of the electrical services panel. The flashing assembly includes a support base including a planar outer surface and a flanged connection assembly extending obliquely from the planar outer surface of the support base and defining an opening configured to receive the electrical service panel therethrough. The flanged connection assembly includes an inner surface that is coupled to an outer surface of the electrical service panel for supporting the flashing assembly from the electrical service panel.

Abstract: A duct flashing panel configured to provide weatherproofing for single wall ducts extending through the walls of a structure and having a terminal end extending outside of the structure. The duct flashing panel includes a panel body and an elastomeric collar sized and configured to circumferentially engage the exterior surface of the duct to form a fluid-tight seal between the duct and the collar to prevent fluid migration along the exterior of the duct. The collar includes an annular bead which provides rigidity and strength to the collar to urge the collar into compressive engagement with the exterior surface of the duct.
