These surface mount covers are available in sets of two, and are designed to work with other Webcoat picnic tables and benches. The covers are designed to cover the surface mounting hardware used on some surface mount tables and benches to protect them from moving or vandalism. Each set of covers is designed to fit either 2 7/8” tubing, or 2 3/8” tubing depending on the product in question. In most cases, each piece of outdoor furniture will require at least two surface mount covers to hide all visible mounting hardware. If you have used more than this on your items, you may require an additional set to cover everything. The surface mount covers are constructed from aluminum, and feature a powder coat finish to protect against damage. These covers prevent damage to hardware, add aesthetic value, and assist with preventing vandalism or theft.
