Answer: 
The AC4Z cannot be used to attach a single 2x (1 1/2") beam to a post as its flange is 1 1/2" wide and it must be installed in pairs, therefore a minimum of a double 2x beam would be necessary.

Customer Reviews

Rated 5.0 out of 5 by 6 reviewers.
Rated 5.0 out of 5.0 by A sturdy and flexible construction helper. I bought the cap when I saw that after a tough winter the deck supports on the home I purchased begin to move off the beams. I have a wrap around deck that angles to the kitchen which was designed with 3 anderson sliders like a giant bay window. Standard decking doesn't work and to keep the post steady after lifting the deck a bit with a jack and re- centering I wanted a firm hold to join the deck and the post. I was able to flex the top of the post cap on one side so it followed the taper of the deck and set everything with decking screws. Nothing will move now and I am confident that I wont end up with a costly repair later or worse- a falling deck. May 10, 2016
Rated 5.0 out of 5.0 by Simple, works great The zmax 4x adjustable post cap is solid and simple to install. Gives a strong bond, couldn't be happier. May 31, 2016
Rated 5.0 out of 5.0 by great love them easy to use will buy em again easy to use for my project strong January 5, 2016
Rated 5.0 out of 5.0 by DIY projects The ties were easy to install and very helpful in the instellation of my project. The metal ties, ties the wood material togeather to make it stronger than just nailing wood to wood. The ties were of great quality heavy metal to give the wood strenth. April 22, 2015
Rated 5.0 out of 5.0 by Updates I think this is an older image, because the 4X4 post cap that I just got at HD has less round openings and more triangles openings. I guess this means that you don't need as many connectors. I hope I never have to use these...they are for seismic retrofit application. September 22, 2014
