Abstract: Louvered roof systems are provided with one or more louvers. Such louvers can be combined in an assembly that is movable between an open condition and a closed condition. In the closed condition, louvers in the assembly engage one another. In such engagement, a leg extending generally transversely from one louver may include a wing that extends generally transversely to the leg and that abuts a surface of an adjacent louver. Additionally or alternatively, in such engagement, a leg extending transversely from one louver may be received in a notch in an adjacent louver.

Abstract: A plastic drain pipe for drainage includes a first end, a second end, and a pipe sub-section between the first end and the second end. The pipe sub-section includes a collapsible section of corrugated pipe, a first non-collapsible section of corrugated pipe, and a second non-collapsible section of corrugated pipe. The collapsible section of corrugated pipe has a first joining area and a second joining area. The first non-collapsible section of corrugated pipe is connected to the collapsible section of corrugated pipe at the first joining area, and the second non-collapsible section of corrugated pipe is connected to the collapsible section of corrugated pipe at the second joining area. An outermost diameter of the collapsible section of corrugated pipe is approximately the same as an outermost diameter of the first non-collapsible section of corrugated pipe and an outermost diameter of the second non-collapsible section of corrugated pipe.

Abstract: A universal gutter hanger assembly includes a hanger body having a front end and a back end. A front attachment feature at the front end of the hanger body is configured to engage with a front end of the gutter. A back attachment feature at the back end is configured to engage with a back end of the gutter. The back attachment includes a clip extending upwardly from the back end and configured to engage with gutters having various configurations of back ends. In some examples, the hanger body includes an arcuate-shaped bottom surface that extends from the front end to the back end.

Abstract: A drainage pipe fitting includes a cuff that permits the fitting to be coupled with pipes or fittings of various sizes. The cuff includes a plurality of sloped surfaces. For example, the cuff may include a first set of sloped surfaces and a second set of sloped surfaces on an interior of the cuff for receiving different-sized pipes or fittings on the interior of the cuff. The cuff may also include a third set of sloped surfaces, a fourth set of sloped surfaces, and a fifth set of sloped surfaces on an exterior of the cuff for receiving further pipes or fittings of different sizes on the exterior of the cuff. If desired, the cuff can include more or less sets of sloped surfaces. In some cases the sloped surfaces are arranged on internal and external fins of the cuff.
