If you are worried about your park furnishings staying in place, then the AAA Playground Surface Post Mount is for you. It will securely mount your furnishings to any hard surface, such as concrete or asphalt. In particular, this mount is designed for AAA Playground Plastics recycled plastic posts, such as those used with the Large Message Center, Large Zig-Zag Hinged Message Center, Medium Hinged Message Center, Medium Message Center, Small Hinged Message Center and Small Message Center. While these are the ideal options for this post, it can be used with any 4-inch square post. The surface post mount is composed of a heavy duty black steel mount. Secure the posts into the mount by using the pre-drilled holes and screwing through them into the recycled plastic post. Pre-drilled holes also make securing the mount to the ground easier. AAA Playground Surface Post Mounts must be purchased individually. Screws are not included with the mount.
