New materials, configurations, and features are greatly expanding the use of traditional wire management systems and their components.

Communications interfaces are keeping pace with growing premises wiring and wiring management systems. New fittings for fiberoptic and Category 5 cabling in raceway systems allow cables to be routed around corners, elbows, and tee fittings while controlling cable bending in excess of 1.25 in., in accordance with the Commercial Building Standard for Telecommunications Pathways and Spaces, EIA/TIA-569. Bend radius fittings also allow the cable to be laid in the raceway without being subjected to pulling tension or stress. Easily interchangeable inserts and a common interface simplify original installation and later alteration of low-voltage twisted pair, coaxial, and fiberoptic cables. Modular raceways fill out the picture, by allowing expansion and adaptivity. One raceway, for example, allows the addition of snapped-in fittings, compartments, and covers. A modular power pole allows you to create exactly the pole you need. Also, you can buy a modular underfloor duct system, modular cable tray, and other modular wire support and wire management systems.

A new data cable support rack is made of aluminum that maximizes the strength-to-weight ratio, provides finish durability, and offers excellent grounding capabilities. Aluminum is easy to modify in the field and provides excellent manufacturing opportunities. Center rail-configured trays provide maximum freedom for cable installations and require only one splice. The splice, which inserts into the center rail, requires only two bolts to secure it. It's self-aligning, covers the center rail ends for cable protection, and utilizes the hardware vertically so the bolt threads are not in the cable fill areas. Pre-threaded holes in the splice unit eliminate nuts, which the installer invariably drops at the worst possible time. All fasteners use the same wrench, instead of 18 different sizes. The system is an excellent choice for congested applications, such as above a ceiling.

There's a new PVC-coated intermediate grade conduit. PVC and enamels form the coating instead of zinc. The advantages depend on the particular installation.

Specialized fixture mounting kits save time and money. There are kits for many different applications. For example, a new lighting fixture installation kit comes with a fiberglass reinforced nonmetallic four-in. box (approved for 15-lb fixtures) rated for a two-hour wall and ceiling fire mark, an installation block, and a "pop-in" non-metallic sheathed cable clamp.

The upper limit on ceiling fan boxes has been pushed higher with the introduction of a new box. Made of fiberglass reinforced polyester resin, the box is so strong and rigid, it's rated for fan weight up to 35 lbs. (a fixture weight up to 50 lbs.) and has a two-hour wall/ceiling fire rating. Each box comes individually packaged with instructions and required hardware. You can order the boxes with factory-installed K clamps at no additional cost.

A new corrosion-resistant fiberglass cable tray is available in either polyester or vinyl ester construction. All components incorporate UV inhibitors and a surfacing veil to resist corrosive elements. Paper mills, refineries, and laboratories are some applications that benefit from this technology.
