ROHN’s R-25AG 25G standard top section features the same 12 1/2 in face and 5/16 in solid serpentine zig-zag bracing as the standard 25G tower sections and it also comes with a tapered top and integrated 2 in OD x 8 1/4 in mounting pipe and set screw. The pipe comes with a factory-installed (and removable) 1 1/4 in tower mast bushing in the top.BRBRYou can connect the 9 ft long R-25AG to any standard Rohn 25G tower section using the included bolts and double-bolted leg connections. The entire section has been completely hot-dip galvanized for years of worry-free corrosion protection and it can be used in guyed, self-supporting and bracketed tower configurations.
