Positioning Hinges When Changing Dock Orientation - Wider to Narrower
The methods in Images 5 and 7 of positioning the hinge plates works well for all straight
dock connections (for example a straight 3 section dock where all sections are
connected end-to-end) and for when a dock connection does not change width
(example: 4ft dock connected to 4ft dock, 8ft dock connected to 8ft dock, etc.) Working
from shore outward into the water, if the dock system A) goes from a wider dock to a
narrower dock (example a 6ft wide dock to a 4ft wide dock) or B) changes direction
(example a "finger dock" that comes off the side of a dock section) we must manually
measure the placement of the hook hinge plates.
Looking at scenario A first, let's suppose that we had a straight dock system that was 6ft
wide. If for the last section we wanted to add a section that was narrower at 4ft wide,
the distance between the hook hinge plates would have to be set up for use with the pin
hinge plates on the last dock section of 4ft wide dock. When outfitting the end of the
6ft wide dock with the hook hinge plates, we would need to measure the distance
between hook hinge plates to fasten them in the correct position (Image 8).

* When connecting from an 8ft or 6ft wide dock to a 4ft wide dock the distance
between hook plates should be 45-3/4".
*When connecting an 8ft wide dock to a 6ft wide dock the distance between hook
plates should be 69-3/4".
Looking at scenario B, the same rules apply. Let's suppose we had a straight dock
system consisting of 3 dock sections 8ft long each (24ft total) with dock1 being closest
to shore, dock2 in the middle, and dock3 at the end. If we wanted to run a 4ft wide
"finger dock" off the side of dock2, we'd need to mount a hook hinge set to the side of
dock2. The distance between the hook hinge plates mounted to dock2 (Image 8) would
need to be set to match the pin hinge plates on the 4ft wide "finger dock".

Working from shore outward into the water, whenever dock width goes from narrower
to wider a Tip Adapter must be used.
