Conduit fittings and accessories are used to secure and route electrical wiring within a structure. Commonly used to protect wiring from abrasion, moisture and other environmental hazards, these components are essential for any electrical system application. Fittings such as couplings, elbows, bushings, sweeps, and straps allow installation of conduit in hard to reach places, while other accessories such as elbows, bushings, and sweeps have special features that enable efficient electric wiring. When used together, correct selection and proper installation of conduit fittings and accessories can produce an efficient and safe electrical system.
