5 Bridge ChannelBridge Channels provide Support for horizontal transmis-sion line runs as well as protection from hazards, such asfalling ice. The channels are formed of 11-gauge (3 mm)steel and are hot-dip galvanized after fabrication. All slotsare 7/16" (11 mm) x 7/8" (22 mm) long for 3/8" diameterhardware. Each section includes ten 3/8" diameter x1-1/4" long bolts, nuts, lockwashers, and flatwashers forsplicing or Support .
