Cable tray total linear weight is the combined weight of the cable tray and the installed cables.
* Sway brace and fastener sizes ( A, B, C ) are based on a minimum brace angle from vertical of 45 degrees.
A = Loos & Co., Inc. UL Listed seismic Wire Rope/CableTM brace size.
B = Minimum bolt or hanger rod diameter for brace-to-tray connection and brace-to-structure connection.
C = Minimum expansion shield diameter for brace anchorage to concrete structural element.
X = Loads are too high for the brace assembly and/or fastener at this sway brace spacing.
