A locking retainer can be installed by disposing the slidable support within the internal area, aligning two locking apertures of the slidable support, and applying lateral pressure to a side arm of the locking retainer to seat a locking pin in the aligned locking apertures.

Abstract: A backless electrical box is formed out of a single piece of material, with a front and sides of the box being parts of the same single piece of material. The front of the box has an integrally-formed mud ring that extends forward from a front base of the front. The sides are made out of material bent back from two opposite edges of the front base, bent around to form the four sides. Some or all of the sides may have seams in them, which may be secured by portions of material overlapping along some or all of the height of the sides, riveted or otherwise attached together. Mounting flanges may extend from the other two opposite edges of the front base. Tabs bent downward from the mounting flanges may be used to cover holes in the sides that extend rearward from these two other opposite edges.

Abstract: A plumbing bracket assembly has a plastic main bracket body and a telescoping bracket. The telescoping bracket runs through the main bracket body, and is able to extend to allow the bracket assembly to be secured to structure (such as studs) at both ends, over a range of distances between structure elements. The bracket body is initially able to slide along the telescoping bracket, for desired positioning, but may be locked in place using screws on the main bracket body. Hardware, such a hose clamp and multiple pipe clamps, is initially coupled to the main bracket body. The main bracket body may have a central depression for receiving a relatively large pipe run, and notches or depressions on opposite sides of the central depression, for receiving smaller pipe runs.
