Product Overview

This kit offers you all the necessary Hot-dipped Galvanized Steel Dock Hardware and Foam Filled Polyethylene Commercial Floats to build a Semi-Floating Ramp/Gangway with the following dimensions : 4 or 5 ft wide by 12 or 16 ft long. This Semi-Floating Dock can be installed as a stand alone walkway or it can be added to another dock with a pair of hinges (item #19133 sold separately). When this Semi-Floating dock is installed as part of a whole floating dock system, it assures a smooth transition to the floating dock(s). With these 16-in floats you will obtain +/-18-in freeboard height. Plans and Instructions included will help you build a sturdy Dock of exceptional quality at an affordable price.

  • Suggested lumber size for this kit is 2" x 6" for a sturdy dock that will be light enough for easy seasonal removal but you can also use 2" x 8" lumber.

  • Pair of Dock Hinges, kit #19133 can be purchase separately to connect this semi-floating dock to a stationary or/and a floating dock and it is recommended to combine these hinges with the inside corners brackets. The remaining back plates will then be used on the other dock section if needed for the hinges installation

Got some things I didn't need and didn't get some things I did need. This was my first dock build so I learned and saved money on the actual dock itself. Overall not bad, I got what I ordered and the quality was good.

ARRIVED on time instructions were sparse but by using them and pictures got it done, a little heavy for one 70 year old to handle but with a few friends and some beer got it in the water. It is now decked and we are feeding the fish again.
