Simpson Strong-Tie’s MPBZ line of column and post bases were designed to provide moment resistance by encapsulating the bases with an overlapping sleeve to resist rotation at the base. Available in 4x4, 6x6, and now 8x8 sizes, all three are code listed under ICC-ES ESR-3050 for uplift, download, and lateral resistance, as well as for allowable moment in reinforced concrete footings. The MPBZ-reinforced concrete footings provide higher load values for the connection, giving designers more flexibility. Pricing ranges from $100 to $200. strongtie.com
