Installation Instructions
Guy Support Assembly:
Assemble the guy support to the vent sections as shown in the joint assembly instructions. Once
the guy support is assembled to the vent sections, figure 1, install the 5" long coupler from the guy
support so that it fits directly on top of the guy brackets. On the vent section below the guy
support, attach the 8" long coupler so that it fits up to the bottom of the guy brackets, figure 2. The
guy support is now totally enclosed with only the guy brackets protruding, figure 3. The guy lines
can be attached before or after installation of the couplers.
