It can also be quickly disassembled and tucked away for the winter without taking up a large amount of space. UltraDocks modular design makes adding on or changing the configuration easy. UltraDock comes in 4ft by 8ft and 4ft by 16ft Sections with Thru Flow Plastic Decking. Wheels can be added to either end and sections can be left assembled or taken apart to remove seasonally.
