Simpson Strong-Tie ACZ Adjustable Post Cap - ZMAX Finish
Product Description
−
+
The Simpson Strong‑Tie AC Two‑Piece Post Cap is a structural connector designed to secure a beam or joist to a vertical wood post with more reliable load transfer than angled nailing or screw fastening alone. This two‑piece cap solution wraps the top of the post on opposite sides of a beam, accommodating nominal 4×4 or 6×6 lumber depending on model, and is typically installed in pairs to support framing connections that require robust uplift and lateral capacity.
Constructed from steel with a ZMAX® or galvanized corrosion‑resistant coating, the AC post cap withstands outdoor exposure and treated lumber environments. Its flexible nailing pattern supports both minimum and maximum load capacity by adding nails in designated round and triangular holes, making it useful for both new construction and retrofit applications where a positive mechanical connection is essential.
Key Specifications:
Connector Type: Two‑piece post cap for post‑to‑beam/joist connections
Compatible Lumber Sizes: Available in models for 4×4 and 6×6 posts (nominal)
Material: Steel with ZMAX® or galvanized finish for corrosion resistance
Installation: Installed on opposite faces of the post; requires nails or structural screws per manufacturer instructions
Application: Supports standard beam‑to‑post or joist‑to‑post connections on decks, pergolas, porches, and other outdoor framing
Benefits: By eliminating the need for nailing directly into end grain and providing engineered load paths, this two‑piece post cap enhances connection strength, helps control uplift, and helps preserve wood integrity over time. Its corrosion‑resistant finish and load‑rated design give both contractors and homeowners confidence in outdoor structural performance.
