Abstract: Disclosed is roller assembly comprising: a base; a shaft mounted on the base, the shaft defining an axis; a pedestal comprising a first arm and a second arm, the first arm and the second arm positioned on the shaft, the pedestal movable axially relative to the shaft; and a roller rotatably positioned on the shaft between the first arm and the second arm of the pedestal, the roller movable axially relative to the shaft.

Abstract: Provided herein is a snap-to-grid bracket assembly for use with a fire suppression device. In one approach, a fire sprinkler support assembly includes a suspension frame coupled at an intersection of multiple (e.g., four) ceiling grid support elements, and a bracket assembly coupled to the suspension frame and to the plurality of ceiling grid support elements. The bracket assembly may include a main body coupled to the suspension frame, and a support arm extending laterally from the main body. The support arm may include seating members coupled a ceiling grid support element. The fire sprinkler support assembly may further include a sprinkler drop coupled to the support arm, the sprinkler drop and/or sprinkler head extending through the main body and into the suspension frame. The sprinkler support assembly may be a retrofit solution that couples to an existing suspension frame of a downlight fixture.

Abstract: Disclosed is a method of assembling a roller assembly that can include mounting a pedestal on a base of the roller assembly such that the pedestal is movable relative to the base; and fixably positioning a roller relative to the pedestal such that the roller is movable axially relative to the base.

Abstract: A method of coupling first and second pipe elements in end-to-end facing relationship includes obtaining a coupling, the coupling including an annular gasket, at least one segment, and a fastener, each segment being approximately semi-circular and including at least two ends, each end including at least one of a tongue and a groove, each tongue protruding circumferentially from at least one end, each groove defined circumferentially in at least one end; slipping the coupling onto the first pipe element beyond any groove proximate the end of the first pipe element; aligning the second pipe element in end-to-end facing relationship with the first pipe element; slipping the coupling onto the second pipe element such that the segments of the coupling straddle the ends of the first and second pipe elements; and engaging each fastener to deform each segment into contact with the outer surfaces of the first and second pipe elements.

Abstract: Coupling devices for joining pipe ends include annular gaskets. Example gaskets include pipe interface profiles for sealing performance and manufacturability.
