Power Block
Conservative stability specifications for the Power Block are listed below for the following design
scenarios:
1. 170 mph wind, high seismic, Class 3 Soil
2. 170 mph wind, high seismic, Class 4 Soil
3. 170 mph wind, high seismic, Class 5 Soil
4. 140 mph wind, lower seismic, Class 3 Soil
5. 140 mph wind, lower seismic, Class 4 Soil
6. 140 mph wind, lower seismic, Class 5 Soil
All scenarios assume:
Minimum concrete rating of 2500 PSI
l
An A1 anchor bolt embedment of 9 inches using M16 HAS-V-36 all-threaded rod (ASTM F1554 Gr. 36)
l
anchor rod with HIT-HY 200 adhesive

Note: The Power Block must be centred within the designed stability area.
The concrete pad for the Power Block must either be designed to be site-specific or must meet the
specifications above. In some extreme conditions, a larger pad would be required. For sites with less
stringent seismic, soil or wind conditions, a smaller pad might be possible.
