Titan 4x4 Post Anchor - All Hardware Included Package - w/ Black and Galvanized Fasteners
Titan 4x4 post anchor
We just had a contractor build a carport with a deck on top and replace a existing deck we had. When the post was put in I just didn't have confidence in them, just seemed a little flimsy. My wife and I did some research and found your product and bought a few to try out and boy were we impressed. After installing on two of the post there was a huge difference in the stability. We immediately ordered 15 more to install on rest of the post. I thought installation was very easy and we now have peace of mind knowing that our railing is safe. We also have a friend that is redoing a deck and highly recommend they check out your decking system. Oh I almost forgot about the quick service which didn't hold up our project. Thank you for a quality product as advertised.

This thing is awesome! Decided to add a railing(bad planning) and needed a solution for the corner where I couldn't add a 4x4 to the inside of the rim. I looked at all of the local home improvement solutions for 5x the cost and none seemed sturdy. I placed mine on top of the corner of my framing on the rim joist and blocked around and into the 4x4 that I previously cutoff.(again didn't plan for the railing) doing this gave me a place to sink the lag bolts. It took a little time to get the center hole in the 4x4 just right and a bfh, but very happy with the results and product. My railing is not moving!!

Product exceeds expectations by a mile. If installed exactly per instructions, there will be no regrets. The building inspector wasn't familiar with Titan anchors but after he reviewed the engineering reports that I retrieved from the web site he said "about time someone came out with an anchor that does the job correctly". Shipping was fast and the order was correct. Thanks, most advertisers supply all the pretty talk one can stand; Titan products are amazing.
