Unistrut metal framing systems are renowned for their adaptability and efficiency in electrical support applications. At the heart of this system lies a combination of channels, fittings, and hardware, all designed to simplify installation and provide robust support. Components like the P1753 fitting exemplify the ingenuity of Unistrut, offering specialized solutions within this comprehensive framework.
The Unistrut system leverages high-quality materials to ensure durability and reliability. Fittings, unless specified otherwise, are constructed from hot-rolled, pickled, and oiled steel, adhering to ASTM standards such as A575, A576, A635, or A36. This steel also meets the physical requirements of ASTM A1011 SS GR 33. The pickling process results in a smooth, scale-free surface, prepared for various finishes and applications. Complementary components like maple cable saddles, clamps, and bus bar clamps use kiln-dried maple treated with paraffin for enhanced insulation and longevity. For more demanding applications, porcelain cable clamps, manufactured using a dry process and white glazed, and fiberglass-reinforced polyester cable saddles offer alternative material options.
A key aspect of the Unistrut system is its UL 5B classification. This classification, encompassing strut-type channel raceways and fittings, signifies compliance with Article 384 of the National Electrical Code, NFPA 70. This includes metal strut-type channel raceways with a minimum thickness of .071 inch (1.81mm) and metal or non-metal closure strips at least .040 inch (1.02mm) thick. This UL listing underscores the safety and suitability of Unistrut for electrical raceway applications. The system’s design inherently promotes ease of use, eliminating the need for welding, drilling, or complex fabrication. This streamlined approach translates to faster installations and simpler solutions for a wide array of electrical support challenges, especially when utilizing specialized fittings like p1753.
Unistrut channel raceways offer structural integrity and spanning capabilities that surpass conventional surface raceway products. Available in continuous lengths up to 20 feet, these channels form the backbone of a versatile system. They integrate seamlessly with components like p1753 to create raceways, trapeze hangers, cable tray supports, lighting grids, and fluorescent fixture supports. This integrated nature ensures compatibility and simplifies design and implementation across diverse electrical applications.
It’s crucial to note the channel compatibility within the Unistrut system. All electrical components, including fittings like p1753, are designed for use with 1-5/8″ wide channel. They are not compatible with 1-1/4″ or 13/16″ framing systems. This dimensional consistency ensures proper fit and function within the intended system design.
In summary, the Unistrut system, with its comprehensive range of channels, fittings, and hardware like p1753, provides a robust, flexible, and code-compliant solution for electrical raceway and support applications. Its material quality, UL 5B classification, and ease of installation make it a preferred choice for professionals seeking efficient and reliable electrical system infrastructure.
