A concrete pier is required to support the tower assembly. The pier must be strong enough to support the
9-1/2 feet tall structure that weighs 250 pounds. The specific GAI-Tronics installation requirements
outlined in this manual provide a 140-mph wind speed rating (V
ULT
). *Reference AASHTO LTS6 Risk
Category II International Building Code.
The GAI-Tronics No. 84504-301 Hardware Kit contains four anchor mounting bolts, a mounting
template, and mounting nuts and washers needed for installation. Additional materials required to install
the pier are not provided by GAI-Tronics but are shown in the installation drawings for reference.
Determine all conduit entries before pouring the pier.
Figure 1. Model 234 & Model 234SBA shown
Tower assembly installation requires the construction of a concrete pier with a rebar reinforcement cage
using 3,000 psi minimum grade concrete. Installation of the anchor bolts within the concrete is simplified
by using the provided template. Once the concrete has properly cured, the tower body is installed with
the nuts and washers included in the hardware kit. Leveling and spacing of the tower body is required for
proper installation. Detailed information on each of these items is provided in this manual.
