Simpson Strong-Tie MPB44Z MPBZ® ZMAX® Galvanized Moment Post Base for 4x4 w/ SDS Screws

The MPBZ® is specifically designed to provide moment resistance for wood columns and posts. With its innovative sleeve design, the MPBZ encapsulates the post and keeps it from rotating at its base when lateral loads are applied at the top. This provides both the specifier and the contractor with greater design options and the opportunity to reduce the need for bracing, creating more unobstructed views. This innovative off-the-shelf solution has been engineered and tested to save specifiers and contractors the time and expense involved in designing, calculating and ordering custom-fabricated parts. Also available for 6x6 and 8x8 posts.

This Simpson product is designed for construction, connector, fastening, anchoring, and structural applications where dependable performance, durability, and jobsite-ready installation matter.
