ABSTRACT:
A seismic brace or restraint for supporting the spine of lengths of electric cable tray. The seismic brace has a generally U-shaped yoke. The ends of the spines of two adjacent sections of cable tray are supported between the arms of the yoke. A cap over the yoke is supported by a hanger rod. The hanger rod inhibits the cap from moving vertically. The cap and yoke have formations enabling the yoke to be slid longitudinally of the cable tray into position at the cap with the cable tray spines in the yoke. Lateral struts extend in opposite directions laterally from the cap to inhibit lateral motion of the brace. Longitudinal struts extend in opposite longitudinal directions from the cap to inhibit longitudinal motion of the brace. The struts are supported on side brackets positioned on the cap.
