4' x 4' ShoreMaster RS4 Dock Frame

The 4' x 4' is a good filler section and works well with some platform configurations. Sections can easily be attached end to end, side to side or end to side to create any layout you desire. Adding 45° and 90° sections to the 4' x 10' sections allow you to go even further with your creativity. The dock frame includes stainless bolt hardware and two dock connection brackets. The connection brackets are very easy to install and once installed the first time, there is no need for tools during seasonal removal and install.
