I need to mount an umbrella to 4"x4" pressure treated decking. It needs to be 2 separate mounts (upper and lower as the adjusting mechanism moves along the mid-section of the pole). The pole itself is ~3” wide. Needs to be mounted with ~2" offset from the pole (can't be mounted directly to the wood again because of the mech). It also needs to be strong enough to not rip loose if an occasional breeze comes up (when not in use it will strapped up so big winds aren't a major concern). via /r/DIY http://bit.ly/2DB8LLA
