REV. F & REV. G

25G

GENERAL USE The 25G is available in the standard 10’ section length and a 7’ length which is UPS shippable. The 25G uses double bolted joints, proven to be the best method of joining tower sections for sturdiness and dependability. As a guyed structure, the 25G standard designs rise to a height of 190’.

FEATURES • Completely hot-dip galvanized after fabrication • Built on an 11 1/4” equilateral triangle design • High strength tubular legs joined by Zig-Zag®

cross members • Each 7’ or 10’ section contains all required nuts and bolts shipped with section • Continuous solid round steel bracing

CAUTION Mixing copies of ROHN towers with ROHN towers is dangerous and voids all engineering and warranty data supplied by ROHN. Materials used by others are not the same quality and have not been tested or engineered by ROHN. Mixing ROHN tower sections with non-ROHN products may cause tower failure or injury.

Per Rev G requirements, any structure greater than 10’ requires a climber safety device. Please see page 40 for ordering information.
