Codes, standards and regulations are developed, maintained, and promoted by regulatory agencies, engineering societies, and trade organizations.

Electrical conduits and fittings are lengths of solid tubing used to house, protect, and cover electrical wiring and cables in power distribution systems.

Wiring ducts are rigid trays typically used as raceways for cables and wires within electrical enclosures.

RS-232, RS-422, and RS-485 are standard interfaces approved by the Electronic Industries Association (EIA) for connecting serial devices. They are serial communication standards providing asynchronous communication capability with hardware flow control, software flow control, and parity check

D-subminiature or D-sub connectors are sturdy electrical connectors with a mating face shaped like the letter D. They provide polarization because male and female connectors can fit together in only one way.

Wire rope fittings includes clips, sleeves, stud ends, eyes, forks and other hardware used to construct mechanical cable assemblies.

Rack enclosures (rack cabinets, laboratory enclosures) are used to house standard 19 in. rack-mounted components or other standard-sized devices.

Specialty or proprietary products and accessories related to cabinets, racks and enclosures.

Enclosure and rack accessories are products and components for industrial, electronic, and computer racks and enclosures.

Towers, poles and support structures elevate, support and/or position personnel and equipment such as antennas, lighting, surveillance cameras or sensors, wind turbines, weather instruments, and power lines.

RF waveguide phase shifters are two-port waveguide modules that alter the phase of an output signal in response to an external signal.

RF waveguide assemblies include such waveguide components as bends, twists, straight sections, short sections, offset sections, and others.

RF waveguide couplers are RF circuits used to sample RF frequency transmissions by coupling (combining) signals asymmetrically.

Specialty IC interface devices are specialty or proprietary products related to IC interface devices.

RF waveguide components are circular, elliptical or rectangular metal tubes or pipes through which electromagnetic waves are propagated in microwave and RF communications. The wave passing through the medium is forced to follow the path determined by the physical structure of the guide.
