Abstract
The present disclosure provides a cable tray fitting with tray connector and a flexible membrane with opposite longitudinal ends. The tray connectors are secured to the opposite longitudinal with each being secured to one of a pair of adjacent cable tray sections. The flexible membrane allows relative movement between the cable tray sections. The disclosure provides a cable tray assembly including first and second cable tray sections each with a longitudinal end. The cable tray assembly includes a cable tray fitting secured to and disposed between the longitudinal ends of the first and second cable tray sections. The disclosure provides a method of assembling a cable tray assembly by securing a cable tray fitting to opposing and adjacent longitudinal ends of first and second cable tray sections and allowing the cable tray sections to move in three dimensions relative to one another by virtue of the flexible membrane.
