*The capacity of CHANCE Helical Pier Foundation Systems is a function of many individual elements, including the capacity of the foundation, bracket, anchor shaft, helix plate and bearing stratum, as well as the strength of the foundation-to-bracket connection and the quality of anchor installation. The last row of the table shows typical capacities of the CHANCE Helical Pier Foundation Systems that are achievable under normal conditions. Achievable capacities could be higher or lower depending on the above factors.
