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.

Systems and methods for routing a plumbing line within a wall include tracks having clip-retaining mechanisms and being attachable within the wall by flexible fins; plumbing-retaining members for gripping the plumbing line and being removably anchored to the clip-retaining mechanisms; and caps and covers removably securable to conceal the plumbing line within the wall.

A method of installing a cable finger accessory in a cable manager includes: positioning a first semi-arcuate clamp section against a section of an extruded support member of the cable manager; positioning a second semi-arcuate clamp section, which is hingedly connected to the first semi-arcuate clamp section, against an opposite side of the section of the extruded support member such that, together, the first and second semi-arcuate generally surround the section of the extruded support member; and fastening a clamp mechanism connected to a distal end of the first semi-arcuate clamp section and adapted to secure the distal end of the first semi-arcuate clamp section against a distal end of the second semi-arcuate clamp section such that the first and second semi-arcuate clamp sections are secured against the section of the extruded support member. The cable finger extends outwardly from at least one of the first and second semi-arcuate clamp sections.

Methods and devices for reducing stress and for increasing the load-hearing capacity of cable racks supporting electrical power and communication conduits and cables having increased versatility for conduit and cable sizes and quantities. Underground devices including rack arms for these applications are desirably made from plastic or composite materials. Rack arms desirably include openings for tying down the conduits and cables atop the arms. While non-metallic materials are designed to withstand environmental stresses, they typically have strength and rigidity properties less than the metallic structures previously used in such applications. Non-metallic rack arms with such openings may be reinforced locally with a stress attenuator or with ribs to increase their load-bearing and buckling capacity and to reduce their stress, strain and deflection under load. A stress attenuator may be made by increasing the in-molded thickness of the web in areas adjacent to or surrounding the tie-down openings.

The tube management assembly employs a track, one or more mounting clips that are slidably mounted in the track and clamps that are snap-fitted into the mounting clips. In one embodiment, the mounting clip has a pair of resilient walls with inwardly directed lips for engaging in arcuate grooves in the sides of the clamp. In another embodiment, the mounting clip has a base slidably mounted in the track and a mounting block extending from the base and including a recess for receiving a tube transversely of the track.

The invention relates to a modular clamping system for fixing a plurality of supply lines, for example, for tension relief in energy chains, and to a clamping part therefor. A plurality of identical clamping parts are stackable one atop the other and hold to each other, wherein each clamping part has a first clamping jaw having a clamping surface and a second opposite clamping jaw facing away, having a clamping surface. A receiving channel for a line that is to be fixed is delimited between the clamping surfaces of facing clamping jaws. According to the invention, in each clamping part, at least the first clamping jaw forms at least one recess, in which a second clamping jaw of a following, identical clamping part can penetrate, crosswise to the lead-through direction of the lines, wherein the free cross-section of the receiving channel is reduced further compared to a non-penetrating position.

A subsea control bundle umbilical comprises: a carrier pipe; a bundle of elongate functional elements being tubes and/or cables that extend longitudinally within the carrier pipe; and spacers spaced apart longitudinally along the bundle. The spacers support the functional elements of the bundle and are movable longitudinally relative to the carrier pipe upon insertion during assembly, and also during installation of the umbilical and in use. As the umbilical does not convey production hydrocarbons flowing from a subsea well, any tubes within the carrier pipe have an inner diameter of no more than 70mm. Any such tubes contain only a control fluid or a service fluid for supporting production of hydrocarbons. Each spacer comprises a stack of blocks and an opening that extends along a longitudinal axis through the spacer at an interface between abutting blocks of the stack. Each opening receives a respective elongate functional element of the umbilical.

A suspension assembly (10) comprising: a support member (12) for supporting an item; an elongate suspension article (14) defining a securing opening (30); and a securing device (16) on the support member (12). The support member (12) defines an aperture (38) through which the suspension article (14) can be inserted. The securing device (16) has a securing member (68) movable across the aperture (38) between a securing position and a non-securing position. The securing member (68) is receivable through the securing opening (30) in the suspension article (14) to secure the support member (12) to the suspension article (14) when the suspension article (14) is received through the aperture (38) and the securing member (68) is in the securing position.

A double gripper for gripping and handling cable ends of two cables of a twisted cable harness in a fitting station for provisioning plug housings includes two gripper jaws each with an upper member arranged above a lower jaw member. The double gripper further includes two engagement members arranged between the upper and lower jaw members with which the cables are supported. The engagement members can be moved independently from the gripper jaws. A distance between the cables can be varied by moving the engagement members between the cables transverse to longitudinal axes of the cables. Each of the engagement members is formed as a wedge with at least one effective wedge surface.
