Innovative Moment Post Base

Now Available for 8x Posts

The MPBZ moment post base is now available in a nominal

8x size to support 8x8 wood posts. The MPBZ is the

ﬁrst product of its kind speciﬁcally designed to provide

moment resistance for wood columns and posts. With

its innovative sleeve design, the patent-pending 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. It’s also available for

4x4 and 6x6 posts.

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 in outdoor structures.

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.
