New 316 stainless steel Adjustable Bimini Mount allows you to install bimini tops on boats at mounting points that are angled or rounded where conventional top mounts just won't work. The UniMount provides a solid base to install conventional radius or deck top mounts at any angle necessary for a strong, positive, neat and clean installation. The base L-W-H dimensions are: 2" - 1" - 1". The distance between the center to center of the holes is 1-1/2"
