ROHN 45G Tower Base For Flat Roof Mount FR45G

ROHN FR45G Flat Roof Tower Mount Base

The FR45G bolts directly to a Water-tight and Reinforced Flat Roof Surface for a guyed 45G Tower, but Cannot be Used as a Self Supporting Base Plate (see R-SB45G). This Tower Base uses double bolted joints which are proven to be the best method of joining tower sections for sturdiness and dependability. The 45G tower can be used guyed, self-supporting or bracketed configurations according to specifications in the ROHN catalog. As a guyed structure, it can rise to a maximum of 300 feet. However, Roof Mounted Tower Options may limit Potential Height considerably. Self-supporting and bracketed heights depend on loading and are also specified in the ROHN catalog .

There is no Wind Load vs. Height Guidance to be found this type of Mounting in any of the Specification Literature for good reason... You need to Consult an Engineer to determine the Load Bearing Capability and Wind Speed Survivability of such an Installation. Guying is an absolute must, but remember that guying will simply increase the down pressure onto the Base support, which in this case, is your Roof! I would imagine that any Roof mounted structure is going to attract the attention of other Building Owners, Code enforcement and the Insurance adjuster. If you cannot find someone local to evaluate the registered plans for your Flat Roof Structure, ROHN may be able to put you in contact with someone who can.

Since there are various other Manufacturers of Towers and Tower accessories that copy the ROHN Tower design, if you are not sure of the manufacturer of your Tower, you can at least compare the actual measurements and design of yours to those found in the spec. sheets in the ROHN catalog section via the Link provided above to assure yourself that additional sections or parts will fit. We cannot make that determination for you as the ROHN clones are something we don't carry or otherwise represent in our Product line. All towers in the GT Series are constructed with high strength steel tubing and feature ROHN's exclusive Zig-Zag ® solid rod bracing to provide exceptional strength. All GT Series Towers are hot dip galvanized after fabrication. In this process, each section of the tower is totally immersed in molten zinc, allowing every square inch of the tower, inside and out, to be completely covered. Hot dip galvanizing protects all points of welding and construction against rust and corrosion while providing an attractive finish.

The 45G is a true multi-use structure that provides excellent strength for applications up to 300´. It´s offered with either heavy steel tube legs to satisfy a wide variety of needs under varied conditions. When properly installed, the standard tower will support the loads shown on various guyed and self-supporting information sheets in the ROHN catalog.

Most Restrictions Allow for 45 feet of Height without the Necessity of Guy Wires, Anchors or Braces. However, No Tower is self supporting during construction! Always use temporary guys on the top most section, and install permanent guy wires as soon as a guy point height is reached.
