Design Comments

I like the overall design of the product, however there is one area that could be improved. The website refers to the use of carriage bolts, which under normal circumstances have a square shoulder just under the head of the bolt. The square shoulder of the carriage bolt does not fit into the hitch or hinge mounting holes cleanly as the mounting holes are round. This is not an issue for the hinge side because the bolt and nut (or head of the bolt) can protrude without affecting the connection of the hitch to the hinge. However, it is an issue for the hitch side, particularly on the lower mounting holes. The lower jaw will not travel freely to a low enough position to provide enough clearance for the spindle to fit into the jaw if a bolt head or nut is protruding into its path of travel. The two possible solutions to this issue is 1. Find carriage bolts that do not have square shoulders beneath the head, or 2. change the design of the hitch to have square mounting holes that accept regular carriage bolts. My suggestion is option 2, as most dock hardware uses square holes to accept carriage bolts. The way I got around this issue is that I found by (really) tightening the bolts the square shoulder of the carriage bolt recessed into the hitch plate, that is the aluminum was soft enough to deform and allow this to happen - however, I don't think this is a good installation strategy. Square mounting holes would be a much better solution.

Dock hinge

The hinge is great when its on and connected. But its a real pain to fit, especially when both docks are floating on water.. Maybe some instructions or guidance would help. This was my first dock so I really took my time.

simplest dock hinge ...

I'm using several dock-hinge for gateway and floating dock. The practical benefit for connecting and disconnecting is my value add. My goal was to move the gateway/docks as a one man show. Now this is reached. Werner Zollinger
