Document ID: 100782
NEMA FB 2.40-2016   [DOWNLOAD]   [BUY]

Provides recommended installation practices for fittings used to compensate for expansion and contraction in electrical raceways due to shear and lateral forces. When properly selected and installed, these fittings prevent harmful stresses in the raceway system and to supporting structures by safely permitting three-dimensional (linear, angular, and parallel) movement of the raceway.
