This 4' x 8' QP-427 aluminum dock model meets the demand for lightweight, easy-to-install docks. It is sturdy, modular
and simple to assemble. It can be installed on piles or on wheels and you can quickly adjust its height. Its configuration
can evolve according to your needs and it can easily be expanded by adding sections. Note that this dock structure
cannot be installed with floats or used as a floating dock starter section. Although your QP-427 has many of the features
of the QP-427-D dock (which is 12' long), its width is different, which restricts combinations with it in straight lines.

CHARACTERISTICS OF A STATIONARY DOCK
> This is the ideal option for shallow water. You can install a stationary dock in a maximum of about 4 feet of water
otherwise installation and removal will be difficult.
> The stationary dock is usually installed without anchors and you should not rely on it to hold your boat during a storm,
or to protect it from large waves created by other boats.
> A stationary dock is recommended if bad weather causes waves of up to 3 feet. If this is the case, you will have to moor
the boat away from the dock. Some people choose to install a boat lift or hoist it up a mooring ramp.
> A post dock is not recommended in a body of water that often fluctuates more than 2 feet in a short period of time. A
floating dock would be more appropriate in this case, otherwise you may have to adjust its height several times during
the season.
> Never leave a stationary dock in the water for the winter because of damage caused by spring ice movement and the
weight of snow. When storing, remove the posts and leave your decking in place. They can be stacked flat (upside down
to prevent wood fading from the sun) or vertically on their sides.

Before starting assembly, we strongly
recommend reading the instructions on page 5
as configuration adaptors may be combined with
the structural parts.
Place the parts to be assembled on the floor to
visualize the steps to follow. Combine the
aluminum parts by following the steps illustrated
below. Screw the nuts by hand to start and once
completed, tighten the assembly.

MAINTENANCE Aluminum requires no special maintenance. However, due to exposure to air and water, a thin greenish layer can
accumulate on its surface. If light scratches appear, you can remove them with a plastic scouring pad, but neither green moss nor
light scratches will affect the strength of the dock.

Insert the 2 End Pieces with Leg Holders into the Side Beams and secure with the 1/4" x 1-1/4"

Locate the holes in the Side Beams, in the center of the dock, to attach the Center Piece.
It should be installed, as shown, with the 1/4" x 5/8" bolts.
Install the 1/2" x 1" bolts, with the threads ideally coated with white grease, into the leg holders
at one end of the dock. Insert the posts, but tighten only slightly as you will readjust once in the
water. Install the junction plates at the end opposite to the posts (except for the first dock section
which does not require junction plates).

You will assemble the 2 decking panels upside down and then turn them over. This way, you
will not see the screw heads on the finished product. Place the Decking boards (a) on the
frame, with their nice side down, all leaning against the same side. Place 4 decking supports
(b) 2.5" from the sides and the other 2, in the center.
As shown on page 2, Multinautic® offers a pre-configured Cedar Decking Kit.
This decking kit has its own assembly guide.
If you prefer to purchase your own wood for installation, here are the required
components and steps to follow:
> 110 deck screws #8 x 1 ¾”
> 10 (or 11: read Step 4) cedar planks: 5/4 in. (actually one-inch thick) x 6 in. x 8 ft.
For ease of handling, you will assemble the decking in 2 panels.
1
Cut the boards into 44 7/8" (113.3 cm) lengths. Make a small cut in 2 of the boards to fit the
corners (1/4" or approx. 6 mm).
If you are installing more than one section, to save on wood, you can split the boards that
will be used as decking supports to assemble the panels (choose the less nice pieces).
Before screwing these decking supports into the boards (6 screws per board), make sure
that the gaps between the boards are equal (+/- 3/8'' or 9 mm) and that the decking
supports are positioned parallel. For smaller spacing, rather than 16 boards, install 17.
Pre-drill these supports at their ends with a 9/64" drill bit to prevent cracking. When
screwing, make sure that the support is well rested on the board and that no space is
created between the two pieces.
Install the structure at table height, with 4 posts (or any kind of support at one end if you
only have one dock section). Check the squareness by measuring it in an X-shape from
corner to corner. The 2 dimensions should be +/- 1/8 in. (4 mm).

Once assembled, turn your panels over. Drill a 11/64" hole in the corner of a panel,
through the wood and the aluminum support lip and insert a screw. Do the same at the
other end of the board and repeat in the other 2 corners and in the center of the panel.
Then repeat the steps with the other panel.

MAINTENANCE Important: your aluminum structures must not come into contact with green ACQ treated wood.
We strongly recommend choosing cedar: it is light, maintenance-free and can be installed as is. Refer to your wood
dealer if you wish to apply a protector.

Plan the installation of your docks according to the possibilities shown in the diagrams beside.
Whether end-to-end (A), "L" shaped (B) or parallel (C), there are many possible combinations.
Note that:
> the Junction Plates (A), for a straight line installation, will be combined with the Leg Holders
with the stainless steel hexagonal bolts;
> the Corner Adapters (B) will use the bolts of a Leg Holder and their own 1/2" bolts with nut.
You will need to drill the Aluminum Side Beam with a 1/2" drill bit to install them. Depending on
your use of the dock, it may be necessary to add a post in this corner;
> the Parallel Adapters (C), which are used to create a platform, will use their own 2" round head
bolts to be connected to the wings of the Leg Holders;
> to create combination "D", you will install the Corner Adapters (B) using their 9/16" x 1" bolts
with nuts and drill the aluminum with a 1/2" drill bit. You will also need additional posts.
Whatever your configuration, the first section will be placed on the ground and the 2 posts will
be located in the water. Note that the first section does not require junction plates.
> The Posts can be inserted into the Leg Holders, high enough so as not to interfere when
moving the dock to its final location; once in the water, adjust them to the right height and tighten
them only slightly. It would be a good idea to coat the threads of the bolts with grease.
> Attach the base plates to the posts, leaving about 6" (15 cm) below the post (a little more if the
lake bottom is muddy or a little less if it is very hard). When you reach the right spot for the dock,
drive the posts to the Base Plates by pressing down with your foot on the Base Plate or by hitting
the Post with a sledgehammer.
> Adjust the height and level of the platform and tighten the top bolts of the Leg Holder. For a
straight line installation, use the bottom bolts to connect the next section on which the junction
plates will be installed. Tighten the 4 bolts of the last section.
> Multinautic® Posts can be cut. Leave at least 16" protruding above the dock for possible
adjustments during the season. Then install the PVC Caps.
> For demanding conditions, you can add reinforcement Braces
(product # 22034 ).
To make installation and removal easier or move the dock as the water level changes, you can add sets of wheels with hubs.
We recommend anchoring a wheeled dock with concrete blocks and chain since the posts will not be driven into the ground
(pair of Anchor Chain Hooks for aluminum docks, product # 22063 ).
