Lineset portal assembly and method

Abstract

A roof top curb lineset portal assembly and method are provided. The portal assembly consists of a portal curb cover, a comb and a top. The curb cover engages a roof curb and defines an opening. The top comprises a roof and two sidewalls. The roof comprises a peak and a sloped roof panel extending downwardly and outwardly from the peak. The side walls face each other and have lower connection sections that are releasably connected to the curb cover. The side walls have lower edges that extend outwardly and upwardly from the connection sections. The comb has at least three fingers defining multiple slots and the fingers extend away from and upwardly from the opening, and are configured so that there is a seal between said comb and said sidewalls.
