To secure the clevis top to the clevis bottom and define an internal area to receive pipe, the first hole can be aligned with the third hole and the second hole can be aligned with the fourth hole, and a fastener can be received through the first hole, the second hole, the third hole, and the fourth hole. At least one of the first hole and the third hole can be surrounded by a first annular flange. At least one of the second hole and the fourth hole can be surrounded by a second annular flange.

Abstract: A bracket is configured to secure a component, such as an electrical box, to a support member, such as a stud. The bracket can include an engagement portion, such as a snap-on arm, configured to interact with multiple surfaces of the support member. A biased or snap-on feature of the engagement portion can be configured to engage a side of the support member to secure the bracket to the support member.

Abstract: An electrical coupling device, such as a surge protector for a rail or other conductive structure, includes a pair of terminals, and a jumper for selectively electrically coupling and decoupling the terminals. Movement of the jumper may expose part of the jumper or one or both of the terminals, such as for use as a test point. A surge module with one or more surge protection features may fit into a base that includes the terminal and the jumper. The module may have an interface feature, such as a protruding post, that prevents engagement with the base if the base is not properly engaged with the rail or other structure. In one embodiment, a threaded rod may serve as the jumper and in one position electrically couples the terminals and in another position electrically decouples the terminals and one end of the threaded rod becomes exposed for use as a test point.

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: An electrical box bracket includes features allowing it to engage multiple surfaces of a stud. The bracket has a front face for mounting an electrical box and a plaster ring, and a far-side tab bent backwards from the front face for making contact with a drywall behind the bracket. The front face has one or more arms that fit over the front face of a metal stud to which the bracket is to be attached. The front face also has one or more flanges projecting rearward from the same opposite sides of the front face, with stud-lock tabs for engaging a side surface or edge of a side flange of a stud. The bracket has legs that extend from the far-side tab, where the legs are foldable by an end-user to engage side surfaces of the metal stud at different distances from the far-side tab.

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.

Abstract: A drop-in loop hanger includes a U-shape portion or saddle for receiving an object to be supported, such as a pipe run, and an arm that guides the object to be supported into the U-shape portion. The hanger may include a moving portion that pivots at a hinge to allow entry of the object, then closes off the entryway to help retain the object within the hanger. The hanger may include a threaded portion for receiving a threaded rod, for example to mount the hanger from a ceiling or other structure or objects. The object may be placed in a series of already-installed hangers, for example placing a run of pipe in a series of hangers that support the pipe at different axial locations along the pipe.

Abstract: An electrical installation bracket includes a body that may telescope to allow the length of the bracket to be changed to accommodate installation in different configurations, for example to accommodate different spacing between mounting studs. The bracket has rails on a face that allow an electrical box to be positioned, by sliding, at any of a variety of locations along the length of the body. The body has holes in it for securing the box to the bracket at a desired location along the body, with a front of the box for example protruding through an opening in the body. The body includes ears on opposite sides of the opening, with mounting holes for mounting the bracket to studs or other structure (or other hardware or devices). The electrical installation bracket advantageously provides more flexibility in placement of electrical boxes, with pre-prepared holes available for securing boxes.

Abstract: A threaded rod hanger has quick lock plunger mechanism that includes plunger pieces within a tapered hole in a housing. The plunger pieces have tapered outer surfaces. A spring within the housing presses the plunger pieces toward the narrow end of the bore, with the spring located between the plunger pieces and a back plate that closes off part of a wide end of the tapered bore. The plunger pieces have internally threaded surfaces that engage threads on a threaded rod that is inserted into the bore, between the plunger pieces. Once the threaded rod has been inserted between the plunger pieces and released, the plunger pieces are pushed toward the narrow bore end. This causes the plunger pieces to press inward, automatically causing the internal plunger half threads to engage the external threads on the threaded rod.

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: An object support includes a clamp, and a base for receiving the clamp, with the clamp securing an object, such as a pipe, to the base. The base may have a trapezoidal shape, with a rectangular bottom surface that is larger than a rectangular top surface. The top surface may have a series of holes for receiving legs of the clamp that are on opposite ends of a linking portion or body of the clamp. The legs are inserted into the base on opposite sides of the object to be clamped, with the clamps legs engaging the holes, and with the linking portion pinning the object to be clamped against the top surface of the base. The legs may have textured surfaces, for example having ridges or threads, that engage the holes to secure the legs to the base.

Abstract: A flexible busbar includes a central conductor (generally of rectangular cross section comprising multiple layers of thin aluminum, copper or other alloys with good electrical properties (conductivity)) and a sleeve having a shape on the internal surface to reduce the adhesion between the two conductors and the sleeve when the flexible busbar is bent, folded, or twisted. This increases the flexibility of the flexible busbar.

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: A receptor assembly for lightning protection of an object, such as a wind turbine blade, includes a receptor disk configured to be placed on a surface of the object, a receptor block insulator with an integral receptor block, a cover that engages the receptor block insulator, and a cap that engages the cover. The receptor disk and the receptor block may be made of electrically conductive materials, and the cover, and the cap, and the receptor block insulator may define a chamber among them that is lined with an electrically-conductive coating sandwiched between relatively high dielectric media to electrically isolate and shield internal parts of the receptor assembly from receiving a lightning strike directly.
