ECHF Explosionproof Flexible Fixture Supports

ECHF flexible fixture supports from Eaton's Crouse-Hinds Division are used in hazardous locations where a light fixture must hang more than 12” from its supporting junction box (as specified by NEC Article 501 and CEC Part I, Section 18).  ECHF supports assure that fixtures hang plumb and will swing freely if accidentally struck, preventing damage to the fixture and supporting outlet fitting.
