1 Tabulated values are for elevator divider beam applications only. 2 Tabulated values must be used in conjunction with the stiffness values shown in Table 331. 3 Minimum safety factor, Ω, for tabulated values is 2.1. 4 Multiply tabulated values by 1.5 to obtain minimum Load and Resistance Factor Design( LRFD) values.

5 Load values are for MT-B-GL EDB A base connector only. The design professional is responsible for checking concrete and fastener strength. Refer to the Modular Support Systems Technical Guide for MT-C-GL A capacities. 6 See Figure 110.
