STEP 2
Insert and bolt in the 2 end pieces with 1/4 in. x 1 1/4 in. bolts by hand (longer part
of leg holder on top). You can now tighten all assembly bolts (BEWARE, aluminum is soft –
DO NOT over-tighten).
STEP 3
Apply grease on the threads of the 1/2 in. x 1 in. bolts and install them in 2 end
corners. Slide in leg piles to required height, but tighten only lightly as you will need to readjust
once in water. Install junction plates to the dock end opposite to posts.
STEP 4
Install base plates on leg piles, leaving approximately 15 cm (6 in.) under the plate
(a little more is required for soft lake bottoms, a little less when lake bottom is very hard).
Tighten securely.
STEP 5
Before installing decking, check squareness of the structure once again so that
118.6 cm (46 11/16 in.) decking planks will easily insert in openings at both ends and in the middle.
DECKING ASSEMBLY
DOCK FRAME ASSEMBLY
STEP 1
Place the 2 side extrusions on a flat
surface (decking support lip on top). Insert central
support with 1/4 in. x 5/8 in. bolts. Be sure there are
2,5 cm (1 in.) from top of support lip to top of square
tube. For now, tighten bolts by hand. Final tightening
will be done when assembly is complete.

need junction plates)
STEP 6
Once the dock frame assembly is put together, install it at about the height of a table with 4 leg piles, checking
the squareness of the structure by taking an “X” measurement from corner to corner. The dimension should be the same
as +/- 4 mm (1/8 in.). If the measurements differ push on the longest part of the frame in order to correct and make sure
that they remain as is when assembling the decking. If the structure doesn’t keep its square shape, tip it on the side and push
in one of the corners.
STEP 7
Install the planks with the smooth (best) side down flush into the dock side support lips (you will assemble the
decking panel upside down in order to facilitate your work and you’ll flip it back later). Align all on one side of the dock, and
leave an equal space between each board (approximately 1 cm (3/8 in.) between each plank). You may use 17 decking
boards instead of 16 for smaller gaps between boards as Multinautic®'s Cedar Decking Kit, #21175.
STEP 8
Once all is positioned flush on one side, place the two 2.4 m (8 ft.) decking support planks at about 30 cm
(12 in.) from the sides and screw in place. You should pre-drill the supports with 9/64 in. bit to prevent cracking. Ensure
that no spaces are created between wood supports and decking boards when adding the screws.
STEP 9
Once your panel is completed, flip it over and centre it equally on each side. Drill six 9/64 in. holes and screw
the panel at both ends and in the middle.

INSTALLATION
Lay the first dock section on your shore, ‘postless’ end on ground and ‘posts’ end in water. Pound posts so the base plates
properly sit into lake bottom. Using the upper bolts on the leg holders, adjust the dock to desired height. Bottom bolts will
be used to set the other dock section. Repeat to complete your dock layout. A distance of about 35 cm (14 in.) with water
is recommended. If desired, cut the top part of your leg piles to the same height (keeping in account seasonal water
fluctuation), then add PVC caps.
