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 concave-convex metal plate of a floor heating system according to the present disclosure includes repeatedly bent concave and convex portions to transmit a load from an upper portion of a finishing material to a floor slab. Because the concave-convex metal plate includes the repeatedly bent concave and convex portions, resistance to the load from the upper portion is significantly improved, thus functioning as a floor structural material that may sufficiently withstand the load, while transferring the load from the upper portion of the finishing material to the floor slab.

Methods and devices for reducing stress and for increasing the load-bearing 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.

A cable manager includes a backbone assembly and at least one side wall extending from the backbone assembly. The at least one side wall optionally includes one or more cable finger units. The backbone assembly includes a spine member having an extruded construction. The spine member includes one or more channels extending substantially an entire length thereof to facilitate easy attachment, removal and/or repositioning of a structure relative to the spine member. The cable manager optionally includes an accessory rod, a half-spool assembly, a cable finger accessory, a strap/buckle accessory, and/or a door assembly having an interference-free hinge set.

An infusion line harness includes a rectangular material with first and second anchor tabs opposing ends of a first longitudinal edge of the rectangular material such as to extend the first longitudinal edge of the material to include a length of the first and second anchor tabs. The rectangular material includes one or more first fasteners positioned on the rectangular material along the first longitudinal edge and one or more complimentary fasteners positioned along the second longitudinal edge and which are configured to connect to the one or more first fasteners, the first fasteners and second fasteners being positioned such that when connected to each other the rectangular material forms a tubular structure. The first and second anchor tabs each are configured to wrap around a respective object and fasten to itself, or to a respective portion of the rectangular material, to anchor the harness to the respective object.
