The present disclosure provides an assembly having a plurality of cable trays, a first cable tray of the plurality of cable trays including a bottom and a set of upright sides extending between a first end and a second end, and a barb and a barb opening along each upright side of the set of upright sides. The barb may extend from an end of the barb opening, wherein a portion of the opening of a first cable tray of the two or more cable trays extends beyond, and remains uncovered by, a second end of a second cable tray of the plurality of cable trays when the first and second cable trays are connected.

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 right angle adapter assembly for mounting a surveillance camera to an eave includes a junction box that has an open end and an exit. The open end is positionable against an eave of a roof to insertably receive electrical wiring. A coupling pipe removably engages the exit in the junction box. A mounting disk is provided that has a mounting face and the mounting disk is attachable to the coupling pipe having the mounting face lying on a horizontal plane. In this way a surveillance camera can be mounted to the mounting face thereby facilitating the surveillance camera to be mounted to the eave of the roof according to manufacturer's recommendations.

A snap-together electric power track apparatus for efficiently transferring electric power to doors in order to energize door-associated electrical devices includes a door access device associated with a door wherein a user comes into contact with the door access device utilizing electrical energy, a power hinge for transmitting electrical power the door, and a device for transmitting electrical energy to electrically energize one or more door-associated electrical devices. Preferably, the device for transmitting electrical energy to electrically energize door-associated electrical devices includes an adhesive- backed current carrying conduit/track that adjustably attaches to the door and transmits electrical power from the power relaying hinge to door associated electrical devices

A cable tray assembly includes first and second cable tray sections. Each cable tray section included a rail including a vertical web, an upper flange, and a lower flange. Each upper flange includes an outboard portion having a downwardly extending tab forming a groove extending along the upper flange. A splice plate assembly connects the first and second cable tray sections. The splice plate assembly includes a first splice plate configured to be retained in the groove extending along the upper flange of the first cable tray section. A second splice plate is configured to be retained in the groove extending along the upper flange of the second cable tray section. The first and second splice plates each define a fastener opening. The fastener openings are alignable with one another and configured to receive a fastener to connect the first and second cable tray sections when the splice plates are attached to the respective cable tray sections.

A cable tray assembly includes first and second cable tray sections each including a base and rails extending transversely from longitudinal sides of the base. A splice plate assembly is configured to engage the first and second cable tray sections for attaching the first cable tray section to the second cable tray section. A bonding jumper is attached to the splice plate assembly such that a first end of the bonding jumper is attached to a first splice plate and a second end of the bonding jumper is attached to a second splice plate whereby the bonding jumper is attached to the cable tray sections without forming holes in the cable tray sections. The splice plate assembly and bonding jumper providing an electrically conductive link between the cable tray sections.

A bracket system mounts to a ladder rack for positioning a fiber trough system above the ladder rack. The bracket arrangement includes a bridge with a slider bar that allows for multiple positions of the fiber trough system relative to the ladder rack in a horizontal direction.

This resin trough body has an approximately U-shape cross-sectional shape that includes a bottom section and side sections on the two sides. Vertical reinforcement ribs are formed at a prescribed interval on the outer surface of both side sections of a trough body of a prescribed length. Further, near the front and back ends of the trough body, horizontal ribs are formed so as to link two vertical ribs. An accommodation space for accommodating a grating lid is formed by a pair of L-shape members being fixed with bolts to a fixing jig that has been attached to the horizontal ribs. The grating lid is accommodated in said accommodation space, and the grating lid is fixed to a bolt fixing section, which is a mounting hole formed in the horizontal plane of the L-shape members.

Disclosed is a length of cable run made of metal wire mesh having a nominal end and a fish-plated end equipped with a fish plate made of metal wires which is configured to allow the fish-plated end to be assembled by clip-fastening with the nominal end of a similar length of cable run; lateral parts of the fish plate each including a flexible arm, a head provided with a ramp and with a clip and connected to the flexible arm by one of its ends, and a spacer secured to the end cross wire of the fish-plated end and situated between this end cross wire and the end cross wire of the nominal end of the similar length when the fish-plated end of the length and the nominal end of the similar length are assembled.

The present disclosure is directed to multi-functional isolation pads that can be used in combination with both clamp-on cable trays and guide-on cable trays without any user manipulation (e.g., folding) of the isolation pad.
