Product Description
The Simpson AC4Z AC ZMAX Galvanized Adjustable Post Cap for 4x by Simpson Strong-Tie is a heavy-duty post cap engineered to create a positive, secure connection between the top of a post and a beam. Ideal for both new construction and retrofit applications where structural support is needed, this connector eliminates the weakness of end-grain nailing and delivers a stronger hold than angled nailing or screw fastening alone.
