A multi-position hinge for the angular connection of two adjacent cable trays, includes a pin that defines a geometric articulation axis, a first member and a second member articulated together around the geometric axis. The first member and second member are each configured to be coupled to a corresponding cable tray. The multi-position hinge Includes two intermediate attachment members. Each of the intermediate attachment members are to be simultaneously coupled to a respective first member and second member and to a respective cable tray Each of the intermediate attachment members includes first coupling means configured to be coupled to a respective articulated element and second coupling means configured to be coupled to a respective cable tray.

A connection assembly includes first and second components which, starting from a separated disassembled state, are joinable to each other along a plane of relative movement parallel to respective planes of extension of the components into an interconnected assembled state, and are transferrable back into the disassembled state. The first component has a latching element on either side of the plane of relative movement, and the second component has two latching element receptacles. In the assembled state, each of the latching element receptacles cooperates with a respective latching portion of a respective one of the latching elements. The latching portions are movable along a movement path starting from a non-deformed rest state. A first portion of the movement path pointing in a disassembly direction with respect to the rest state is limited by stop surfaces against which the respective latching elements rest in a course of disassembling the components.

A method of using a hanger for supporting a load from an underside of a metal decking is described. The metal decking has a trough with a first groove opposing a second groove, and the hanger includes a flexible body which has an unflexed length that is greater than the groove spacing and is adapted to accept a load from a rod, cable, or wire. The method includes inserting the load support assembly through the aperture; contacting the first end of the body with the first groove of the metal decking; flexing the body to decrease the distance between the first end and the second end to a distance equal to or less than the groove spacing; and contacting the second end of the flexible body with the second groove of the metal decking. The body supports the load support assembly between the first groove and the second groove, and such that the load support assembly is movable relative to the flexible body.

A connector (1) for releasably engaging a slot (10) in a support member (11). The connector (1) includes a body (2) in having a blind bore (20), within which is received a retaining element (3), a threaded insert (4) and a bolt (5) with a shaft (50). The threaded insert (4) provides a threaded hole (40) that receives the shaft (50). The bolt (5) has a head (51) at a first end of the shaft (50) and the retaining element (3) is secured to a second end thereof to inhibit removal of the shaft (50) from the body (2). The shaft (5) has a central threaded portion (55) between the head (51) and the retaining element (3) to engage the threaded hole (40) such that rotation of the body (2) relative to the bolt (5) draws the head (51) toward the body (2) to captivate and clamp an overhang (13) of the slot (10) in the support member (11) between the head (51) and the body (2).

A bonding washer for making electrical connection between two metal pieces that are to be mechanically fastened together. The washer, to be interposed between the two metal pieces, may be constructed so as to fasten to one of the pieces before the two pieces are joined. Teeth on the washer, positioned at right angles to the plane of the washer, are forced into each of the two metal pieces when the fastener is tightened, making electrical connection between the two metal pieces.

An installation system for partition panels in a room, the system including at least one upper telescopic group, having sections and constrained to the ceiling, and at least one lower telescopic group, having sections and constrained to the floor, a series of partition panels positioned between the upper and lower telescopic groups with coupling-uncoupling groups, where both the upper telescopic group and lower telescopic group comprise a first section and a second section for coupling with each other, the second section slidingly arranged inside the first section and adjustable with respect thereto, each of the coupling-uncoupling groups comprising a first female coupling element and a second male coupling element, one connected to the second section and the other to the partition panel, which can be engaged with each other by a releasable constraint.

A bow stop is an apparatus that safely aids in the docking of a boat. The apparatus includes at least tone length-adjustable stopper assembly. The at least one length-adjustable stopper assembly includes a telescopic bar, a stopper tube, a bungee cord, a first cradle mount, and a second cradle mount. The telescopic bar adjusts to the length of a boat. The stopper tube presses against the front of the bow. The bungee cord retracts the stopper tube into a neutral position. The first cradle mount and the second cradle mount secure the telescopic bar, and consequently the stopper tube and the bungee cord with the cradle mount. In a preferred embodiment, the at least one length-adjustable stopper assembly is a left length-adjustable stopper assembly and a right length-adjustable stopper assembly. The preferred embodiment further includes a length-adjustable cable, connecting the left length-adjustable stopper assembly with the right length-adjustable stopper assembly.

A splice having a main body and one or more protrusions extending from the main body. The one or more protrusions can be operable to interfere with a rail when the main body is installed into an opening of the rail. The one or more protrusions may be operable to cut into a coating of the rail and form an electrical connection between the rail and the main body.
