Installed the 4X4 backing plate with my mounting system. The plate is sturdy and fits perfectly under the deck. It adds noticeable stability to the setup and feels solid during use.

Good quality material. The anodized finish holds up well to outdoor conditions. I used it with my mounting plate and noticed less flex in the installation.
