  • Patent number: 7013606
    Abstract: A roof pipe chase housing system for allowing pipes to pass through a roof without leaking. The roof pipe chase housing system includes a roof curb, a housing structure attached to the roof curb, and a tower structure attached to the housing structure. The housing structure has a side panel for allowing one or more access openings to be positioned within that receive a pipe in a sealed manner. The housing structure preferably includes an extended lip that prevents water from entering between the housing structure and the roof curb. The tower structure is capable of supporting one or more electrical disconnect switches and other devices.

  • Patent number: 6682051
    Abstract: A wire guide system for facilitating efficient installation of wire within conduit connected to an electrical box. The wire guide system includes a main body having main cutout, the main cutout having an upper curved portion and a lower curved portion for receiving a length of wire, a plurality of extended portions, and a plurality of leg members attached to the extended portions for engaging an inner corner lip of an electrical box. The main body has a generally spherical structure for facilitating receiving and redirecting of the wire as the wire is pulled through the electrical box into a connected conduit. The upper curved portion and the lower curved portion preferably have a relatively consistent radius of curvature for smoothly guiding the wire.
