Hi George, thanks for your question. As long as the deck height is less than 600mm, or roughtly 2 feet, then these anchors would be a great option for you. For deck heights over 600mm, you will need a code compliant rail system. Please have a look at our RailBlazers line of aluminum railing if your deck height is over 600mm. Thanks very much George!

Hi Larry, thanks for your question. We haven't actually tested this to know how paint would adhere to the anchor. One of the paint specialists in your local Home Depot store may be able to help as well. Thanks Larry!

Does it keep the post off the ground so it will stay dry? How far off the ground?

Asked by Posty January 1, 2021

Answers

Hi Posty, thank you for your question. The thickness of the bottom of this post base is approximately 1/4", so the distance between the bottom of the post and the surface on which it sits will be about 1/4 inch. There is also a hole in the bottom for drainage so there won't be any post rot. We recommend using treated 4x4 posts or cedar 4x4 posts. Thank you.
