T-slot interconnects that include a body portion and two orthogonally elongated interlock tabs positioned on opposed sides of the body portion are used for building T-bar structures, including grow-light canopies. In operation, the elongated interlock tabs are placed into T-channels of the T-slot bars and/or T-slot light bars. The T-slot interconnects are then rotated to secure the elongated interlock tabs within the T-channels of the T-slot bars and/or T-slot light bars and, thereby, secure the T-slot bars and/or T-slot light bars together through the T-slot interconnects.

A clamp assembly for securing a conduit to a strut, the clamp assembly includes a pair of brackets, each bracket having a head section and a tail section. The respective tail sections of the pair of brackets being configured to be received within the strut and the pair of brackets having respective apertures formed in the respective head sections thereof. A bolt has a shank that is configured to be received within the respective apertures of the pair of brackets. A nut has a bore therein, the bore is configured to receive the shank of the bolt. Each of the respective apertures includes a pair of opposite, rounded surfaces spaced from each other and connected by a pair of opposite, elongated surfaces.

A trapeze hanger fitting includes a strut connecting portion configured for insertion into an open interior of a strut through an open longitudinal end of the strut to connect the trapeze hanger fitting to the strut. A rod securement portion is connected to the strut connecting portion and configured for securement to a rod to secure the trapeze hanger fitting to the rod. The rod securement portion is configured to be disposed outside the open interior of the strut and longitudinally outward from the open longitudinal end of the strut when the strut connecting portion is inserted into the open interior of the strut.

A roof equipment support includes a platform, a pair of sidewalls extending from the platform, and a top wall extending between the pair of sidewalls and offset from the platform. The platform, the pair of sidewalls, and the top wall define an interior cavity that extends a length of the support from a first end to a second end. A pair of strut extensions extend above the top wall, and each of the pair of strut extension include a hook at a distal end. The pair of strut extensions and the top wall define a substantially U-shaped channel that extends at least a portion of the length of the support, and the platform, the pair of sidewalls, the top wall, and the pair of strut extensions are unitarily formed.

A pipe support assembly including a pipe support shell body and at least one standing saddle element. The pipe support shell body includes a substantially semi-cylindrical wall portion having a length which is greater than a width thereof, and have longitudinal rims; and outwardly extending flanges formed at each of the longitudinal rims of the semi-cylindrical wall, wherein the flanges are provided with through holes distributed over the length thereof. The at least one standing saddle element includes an anchoring portion adapted to be anchored to a support structure and a saddle portion to receive the convex side of the semi-cylindrical wall of the pipe support shell, the saddle portion including snap members at its rims to snap around the flanges of the pipe support shell body.

A roof equipment support includes a platform, a pair of sidewalls extending from the platform, and a top wall extending between the pair of sidewalls and offset from the platform. The platform, the pair of sidewalls, and the top wall define an interior cavity that extends a length of the support from a first end to a second end. A pair of strut extensions extend above the top wall, and each of the pair of strut extension include a hook at a distal end. The pair of strut extensions and the top wall define a substantially U-shaped channel that extends at least a portion of the length of the support, and the platform, the pair of sidewalls, the top wall, and the pair of strut extensions are unitarily formed.

A pipe fixing device includes a fixing portion formed in a channel shape in which a first space therein is opened to an outside through an opening formed in an upper portion; and a support coupled to a lower portion of the fixing portion and made of steel-making slag, wherein a part of upper end edges of the fixing portion corresponding to a front and a rear of the opening is formed to be bent toward the first space.

An apparatus comprising an inner part including an external thread and a slot with a non-circular cross section in a plane perpendicular to the screw axis of the external thread. The slot is configured to locate an elongate member with a corresponding non-circular cross section, such that when located in the slot the elongate member is rotatably fixed relative to the slot. The apparatus further comprises an outer part including an internal surface that comprises a threaded portion, wherein the outer part is configured to threadably rotate around the inner part.

A transverse bar for a chain link of an energy guiding chain for guiding lines. The transverse bar has an elongate main body comprising a first plastic and at both longitudinal ends a connecting region for connection to the side plates. The main body of the transverse bar has two long narrow sides which each have a holding device for separating bars. Provided on the inside of the main body that faces towards the lines is a line-protecting layer for handling the lines gently and comprising a second plastic which is different from the plastic of the main body and is selected to reduce abrasion upon relative movement between a line and the transverse bar. In that case the line-protecting layer extends from one narrow side to the other and at least predominantly covers over the inside of the main body but leaves uncovered the respective holding device at the one narrow side and at the other narrow side.

Disclosed is a pipe vibration-proof channel capable of preventing vibration generated in a pipe from being transferred to the outside. Here, since a vertical channel connected to a horizontal channel on which the pipe is disposed is disposed to be separated from a structural section steel member, it is possible to prevent the vibration generated in the pipe from being transferred to the structural section steel member. Also, since a vibration-proof unit capable of absorbing the vibration of the pipe is disposed on a pipe fixing portion configured to fix a vibration-proof bracket and the pipe, it is possible to prevent the vibration of the pipe from being transferred to the vertical channel.
