4X4 Post Anchors08/01/2011
By David carson
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 lo

Best Anchor I've Used03/06/2013

We just completed our deck this past weekend and I have to say I'm extremely happy with both the performance and ease of use of the Post Anchor's. I have to admit I was a little leery after reading the instructions online that only drilling the center hole 1/2 way deep that the full post was going to hammer into the wood. With the sharpened edge it did with ease. (I would suggest buying the little protector thing as I did mash up the bottom a bit on a few of them with the sledge It did/will not impede the overall performance at all but I would use it next time.) Overall a great product way better then the Simpson Strong Ties I've used in the past which have that tall ugly box at the bottom. The ONLY thing I have to say I was very disappointing in was the "MADE IN CHINA" sticker attached to each one. I thought I was getting a solid Made in Canada/USA product. Come on Titan lets say we keep a few jobs in America... I'd even be willing to pay $2 more per anchor for a MADE LOCAL

Works great for interior railing 10/25/2013
By Randall Rupp
We just build a new house in which I wanted to install a railing around a large opening in the second floor that overlooks the first floor. Also needed railings around the stairway. I wanted to attach our 4 x 4 clear fir posts to the top of the floor and looked for brackets on the web and talked with carpenters. The only bracket that looked reasonable was yours. Installing the brackets was easier than the video implies. (I used a jaw horse to hold the posts while drilling and attaching.) The posts were attached to a trim board on the floor. We are delighted with the outcome. The railing is solid and looks very good. By the way I am an amateur woodworker and am always surprised when something goes well-this project did. I have recommended these brackets to friends and relatives and in fact had a few extra brackets for them to try. I now have to install a railing on my deck and have thought that I could maybe do it less expensively than with Titan brackets. However, since I
