            Hello Clayton, thank you for your interest in our plastic post anchor product. We want to clarify that while you can indeed attach the plastic post anchor to concrete, it is essential to note that these anchors are intended for smaller-scale projects. We recommend avoiding usage for any surface higher than 600 mm (23.62") from the ground. If you plan to utilize these products for a specific project, we highly recommend engaging professionals to assess the suitability of the product for your intended application and to ensure that all structural components align with the intended usage. Should you have any further questions or need more information, please don't hesitate to contact us. Our team is available to provide any necessary support or assistance

              Yes. You’ll need an impact driver to go into cement with proper hardware.

                Thank you for your inquiry. We appreciate your interest in our product. However, it is important to note that each city has specific building code requirements for guard rails. Please be aware that the post anchor you mentioned is not designed or intended for use in constructing guard rails. We strongly advise that you carefully review and ensure that your project fully complies with the applicable building codes and regulations in your region before proceeding. Thank you

                      They're designed to add the post for the railing to an existing deck, yes. You just have to make sure there is blocking or a beam underneath to ensure structural soundness.

                        Hi there, as long as your deck surface is no more than 600mm from the ground, these anchors would be a great solution. They are not designed to form part of a guardrail system that is subject to building code. Thank you.

                          Customers say the post anchors are sturdy, easy to install, and provide a solid support for 4x4 posts, making them ideal for deck railings. Many appreciate the included hardware and the attractive design, although some noted that the quality of the screws could be improved as they tend to strip easily. Overall, users find the product effective for their projects, with a few expressing concerns about compatibility with higher decks and the need for better screw quality.

                          Easy to install, holds the 4x4 in place and looks good. Solves the problem of where to attach the 4x4. Good product.

                          Provided fasteners are bad and need to be replaced
                          While anchors themselves looks sturdy at first glance the aluminum deck fasteners are absolute useless. See attached photo. They cannot bear any load at all and that's something they should! I had to go to the hardware store and buy good fasteners. Now I am worrying about actual anchors how long they will last....

                          Hello Dmitry, thank you for your comments. The anchoring fasteners supplied are 1/4” x 2-1/4” long, and are made from corrosion resistant stainless steel. We recommend drilling pilot holes to reduce the torque load applied to the fastener when installing, and to not over-tighten. To create a water-tight seal, coat the fastener with some non-corrosive silicone caulking prior to installing. This also lubricates the fastener for easy installation. Remember to ensure your project complies with applicable building codes in your area. Please feel free to give our customer service team a call at 877-883-7325 at your convenience should you have any additional questions. Thank you for your support, Dmitry!
                            what a disappointment!!
                            I am disappointed with this. I took the time and money using these which were easy, looks nice, but, after a few months they started to crack around the mounting screws on the sides. I do not feel like they were over tightend. Out of 18 mounts, i would say around 15 are cracked. This would be a major task to replace them with something else. I will not use these again

                              Great product for attaching posts to stone but I did have to shave the pressure treated post to get it to fit. And then paint the post again.

                                Post holders
                                I was skeptical but I wanted to build my deck without post all the way to the ground. I just cleared trees and had massive roots so I couldn't space my post the way I wanted. I used these and was surprised how Ridgid they were.I could move them before bolting them down so I would get a good tight fit on my railing. Very pleased with the results and I would recommend them.
