Description

The MPBZ® is specifically designed to provide moment resistance for columns or posts. An innovative overlapping sleeve design encapsulates the post, helping to resist rotation around its base. The MPBZ is ideal for outdoor structures, such as carports, fences and decks. Built-in standoff tabs provide the required 1 inch standoff to resist decay of the post while eliminating multiple parts and assembly. Additionally, the MPBZ is available in ZMAX® as the standard finish to meet exposure conditions in many environments.
