This is the product that saved my backyard deck project. I built the deck with Trex in 2008, but didn't want to use any of the available railing systems at that time. Two summers ago i found this post anchor and the idea fell into place as to how i could actually build the railing myself. I bought 14 of them and the result, this anchor has done the job. It has been sturdy and stable every sense. This year i needed to change the support system in my front deck and immediately turned to the this post anchor to save the day.

Hi Lawrence, thank-you for your support!
For low decks only
What they don't tell you until you have bought the product and opened the package and read the instruction sheet is that they shouldn't be used on decks more than 24" above ground level. Railings are not required on decks 24" or lower. What I gather from that is that they don't meet the code for structural strength.

Hello and thank you for taking the time to post this comment. I apologize for any inconvenience. This is correct that these post anchors are not engineered or tested to be used as part of a guardrail system on a deck structure that is more than 600mm (23.6"). We have confirmed with our visual merchandising team that these warnings are present on the product label and the installation instructions that come with each item. Please don't hesitate to contact us should you have any other questions at all. Thanks very much - Peak Products (877)883-7325
