Strength at the Bottom to Stabilize the Top

Expand your options for designing open outdoor structures with the new, patent-pending MPBZ moment post base—now available in 4x, 6x and 8x sizes. This innovative connector provides optimal strength at the base of columns and posts to resist lateral loads at the top—reducing the need for knee bracing.

The MPBZ is ideal for freestanding outdoor structures such as carports, fences, pergolas, decks, trash enclosures and screen walls. The moment-resisting post base can greatly reduce and sometimes eliminate – the need for additional bracing.
