Post Anchors (5/5) Nov 4, 2010 Anonymous
  I have used 12 of these both in wood and concrete. Best and easiest to use. Also Richard is the best when it comes to customer service and help.

  A great product but be sure you are working with newer, green wood. We used 6 month old posts and they split terribly. Bought new 4 x 4s and they were PERFECT!
Plus, they look great.

Editor Note:Thanks very much for your comments. Yes, with the 4x4 anchor we do not recommend use with dry wood, kiln dried or otherwise, nor with any knots in the lower 6" of the post. This is highlighted in the instructions and mentioned in the product description on the shopping cart.

This model of the post anchor uses a 1-1/4" diameter tube and was chosen so that it would be optimized for regular 4x4 (3.5"x3.5") and true 4x4 posts.

The tube diameter is right on the margins of optimal performance for both those sizes of posts but that means with wood that is dry, sitting around for a long time, it will have a tendency to crack or split. Not so with "green" wood, or what you buy off the shelf or yard as it is always moist 18%-30% and then will settle to about 12%-15% once installed in the field.

We have a 1-1/8" diameter tube now in testing specifically for use with only nominal 4x4 posts and it is performing exceptionally well so far - even with very dry wood - including hard Douglas Fir!

  I used these to construct a deck railing system using Tigerwood. With a hardwood like that you cannot pound the anchor in - it has to be carefully drilled.

I found that the best way to do that was to drill a hole using a forstner bit first. The hole has to be big enough to clear not just the outside of the hole saw bit, but the top part of the hole drill.

So you need to go larger than the forstner bit recommended on this site - a 1.5 inch bit works. Once the hole is drilled the hole saw then works fine and produces a good sturdy hole with center support. The lag screws must be pre drilled in hardwood, of course. I used 2" screws. The screws had enough strength to square up the bottom of the anchors to the posts. The deck was all ready level so no shims were required.

A note on drilling the holes.

I would not try to drill the holes by hand in a hardwood post such a tigerwood. But, I was able to use my drill press which I believe is a heck of a lot safer and a lot more accurate. All in all after I figured out how to do it it worked very well. I have a single post six feet out that is solid as a rock!

Editor's Note: Very interesting technique although we can't confirm final performance without third party engineering. But we do know that the harder the wood the smaller the fasteners that can be used. Our in house load tests on mid span rail concentrated load between two posts has gone way beyond 800 lbs and actually pulls out the deck screws unless you use a very course and long screw. But again - we can't offer any official engineering guidance on this methodology unless tested in the lab like that.

  Was very unsure about the potential of being able to leverage the post loose. Mounted the first one and was sold, installation is simple and time is definately saved. I will be using these post till I find something better. This is a great alternative to all other expensive bases. I have used my share of the expensive bases and this is by far the best for your money.

  These anchors were the perfect anchor for my deck project. I built a pergola on my deck to help support and attach shade sails. They are the most asthetically pleasing and sturdiest anchors on the market today. I'm so glad I did the Internet research before accepting what was available locally in the box stores!

  I used these covered with skirts to anchor WRC posts for a decorative loft railing, overlooking a kitchen in a little 3rd floor apartment in Cambridge, MA. They worked perfectly and looked good.
great deck posts. (5/5) Aug 1, 2010 Gary Harpold Roanoke Vi US
  I have installed 10 of these post anchors in the process of refinishing my deck. They work great. [...] Will I use this product again? Yes, most definitely.

  I have used these on 3 of my projects and could not be more happy. The are easy to install and hold the post very securly. Also Richard could not be easier to work with. He helped me with many questions I have on installation.

  I used 8 of these on a second story deck over a patio. It worked great and met the Dade County, FL hurricane specs. The installation was fairly easy and straight forward. My 2 lb sledge hammer was sufficient to drive the anchor into the post.
