Abstract: An adaptor is provided that is configured to receive a support assembly for mounting a flexible fire sprinkler fitting in a ceiling support structure formed of parallel, spaced beams. The adaptor includes first and second long sides configured to be secured to each beam of an adjacent pair of beams, and first and second short sides configured to be secured to the support assembly. One end of each long side is joined by the first short side, and an opposed end of each long side is joined by the second short side such that the first and second long sides are parallel to each other and perpendicular to the first and second short sides, whereby the adaptor is a generally elongated, hollow, rectangular structure. The adaptor permits the support assembly to be mounted in a suspended ceiling formed of hat channel or metal stud furring.

Abstract: A clamp for attaching solar panel grids to standing seam roof structures. The clamp includes opposing clamp halves having inter-engageable projections and recesses. One or more fasteners engage the halves to draw them together. A first set of recesses on one clamp half receives a first set of projections on the other half. A second set of recesses on the other clamp half receives a second set of projections. When loose, the first set of projections engage the first set of recesses like a detent, while the second set of projections are spaced apart from the second set of recesses to enable the clamp to be slid down onto the vertical seam of a standing seam roof. Tightening the fasteners causes the second set of projections to deform the seam into the second set of recesses, fixing the clamp to the seam.

Abstract: A coupling system for conduit and pipe is disclosed. First and second conduit sections are disclosed, each of which has first and second ends. The first end has an outside diameter, and the second end has a belled portion with an inside diameter greater than the outside diameter of the first end. The belled portion has an aperture and a raised lip surrounding the aperture. A threaded fastener is rotatably disposed in the aperture and engages threads of the aperture and an inner surface of the raised lip. The raised lip has a predetermined lip height that is selected to provide a minimum number of full threads engagement between the belled portion and the threaded fastener to ensure the belled portion has a predetermined pull out strength. Other embodiments are disclosed and claimed.

Abstract: A clamp is disclosed for attaching solar panel grids to standing seam roof structures. The clamp may comprise a pair of opposing clamp halves having a plurality of inter-engageable projections and recesses. One or more fasteners engage the halves to draw the halves together. At one end of the clamp, a first set of recesses on the first clamp half may receive a first set of projections on the second half. At an opposite end of the clamp a second set of recesses on the first clamp half may receive a second set of projections on the second half. In the loosened condition, the first set of recesses may be engaged in the first set of recesses to act as a detent, while the second set of projections may be spaced a sufficient distance away from the second set of recesses to enable the clamp to be slid down onto the vertical seam portion of a standing seam roof. Tightening the fasteners then causes the second set of projections to deform the seam portion into the second set of recesses, fixing the clamp to the seam.
