Deck Umbrella Mount Backing Plate

This is the exact same plate that is used in the JEWLS SUPER HEAVY DUTY Deck Umbrella Mount - Fits Purple Leaf and the JEWLS HEAVY DUTY Rim Joist Umbrella Mount.

The plate is 0.25" thick stainless steel and is the same bolt pattern as the mount.  It is intended to be used as a backing plate, on the backside of the rim joist, for added piece of mind. It is not required. Size is 6" x 6" x 0.25"
