Abstract: A locking retainer can include a strap that at least partly bounds an internal area and includes a locking arm with a locking pin that extends into the internal area and a release tab extending opposite the locking arm and away from the internal area. The strap can have a locking configuration in which, with a slidable support within the internal area, the locking pin extends into two locking apertures to lock the slidable support at a fixed length. The locking tab can be moved towards the internal area to move the strap into an unlocking configuration in which the locking pin is removed from the internal area to release the locking pin from the two locking apertures.

Abstract: A locking retainer can be used with a slidable support that includes a two support member with respective sets of locking apertures, with the two support members slidably engaging each other to define a support profile. A strap can at least partly bound an internal area and can support a locking pin that extends into the internal area. The strap can have a locking configuration in which, with the slidable support disposed within the internal area, the locking pin extends into two of the locking apertures to lock the slidable support at a fixed length. 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 securement device includes a pair of plungers movable within a housing. The plungers act as quick lock mechanism to engage and secure a threaded rod (or other object) that passes into a hole that runs through the housing. The plungers are spring-biased to position themselves toward so as to provide a radially inward force, for example to engage a threaded rod or device in the through hole in the housing. A spring within the housing presses the plunger pieces toward a portion of the housing where the outer surfaces engage other surfaces to push the plungers inward. The device includes a disengagement feature or mechanism that is used to push the plunger pieces out of engagement with the threaded rod. The disengagement feature may include a disengagement tool, and may include wings, such as on the plungers or on carriers for the plungers, that protrude out of the housing.

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: Embodiments of the invention provide a locking retainer for a slidable support that includes a two support member with respective sets of locking apertures, with the two support members slidably engaging each other to define a support profile. A strap can at least partly bound an internal area and can include a locking pin that extends into the internal area. The strap can have a locking configuration in which, with the slidable support disposed within the internal area, the locking pin extends into two of the locking apertures to lock the slidable support at a fixed length. 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 device is used for gripping and securing cable for the purpose of suspending objects or loads. The device may be a two-barrel device that allows the user to create a loop of cable to secure to a hanging load, or to a structural member. The user of the locking device feeds the cable through one barrel, around an object to be suspended, and through the other barrel. The device has carriers installed in sockets in a housing, with wedge-shape jaws in openings in the carriers able to engage the cable and hold the cable within the device. Pushing or pulling of the carrier is used to release the spring force pressing the jaws inward, allowing the cable to be removed from the device.

Abstract: A J-hook cable support includes a semicircular saddle, a stem at one side of the saddle, and a tip at the other side of the saddle. The stem includes protruding tabs able to engage snap-on brackets in order to engage structural parts, or to couple multiple cable supports together. The stem may have two pairs of tabs at different heights along the stem away from the saddle. The tabs may be bent pieces of the metal of the stem, bent toward the back of the stem, away from the cable-receiving area defined by the saddle. The snap-on brackets may include one or more pairs of notches for engaging the tabs of one or more of the cable supports. A wire retainer may be used to close off the cable-receiving area, with the wire coupled to both the tip and the stem.

Abstract: An electrical box has four sides that define a rectangular space. The box has flanges extending outward from opposite sides, for mounting the box to a stud or other structure. One of the flanges has one or more tabs, outward protrusion(s) that fit into one or more openings in the flange on the opposite side. The fitting of the one or more tabs into the one or more openings allows two such electrical boxes to be conveniently located at the same height, on opposite sides of the stud. The tab(s) and opening(s) automatically align the boxes with each other. The result is an easier and accurate installation, with less time and effort expended.

Abstract: A clamp includes first and second parts, each of the parts having a circular central section and a pair of straight extensions extending away from the circular central section in opposite directions. In the first part the holes are closed holes, while in the second part the holes are open holes, connected by slots to an upper edge of the part. Bolts may be pre-located through the closed holes, with nuts threaded onto the bolts, but not tightened. The pre-placed bolts may be received through the slots and into the open holes of the second part. The nuts may then be tightened against the second part to clamp the circular central sections on opposite sides of a circular object, such as a vertical pipe run, between the parts. According to a variant, the bolts are permanently secured to the first part so as to prevent rotation of the bolts.
