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 4×4, 6×6, and now 8×8 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
