The QP-427D 12 ft (3.66 m) model is an aluminum dock that meets the growing demand for a dock that allows for installation with lightweight
plastic decking. You can therefore choose between polymer panels or wood decking. It is sturdy, modular, easy to assemble and light to handle.
It is suitable for installation on posts or wheels and you can easily adjust its height. Its configuration can evolve according to your needs and it
can easily be enlarged or modified over the years. Although this model has many features also present in the 2.44 m (8 ft.) long QP-427 dock kit,
its width is different, which restricts straight-line combinations. Note that this dock structure cannot be installed with floats.

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.

Insert the 2 End Cross Members in the Side Beams and bolt using the 1/4" x 1-1/4" bolts.
Find the holes located at 23 ¾" from the center of the dock in the bottom edge to attach the cross
members. They must be combined with the shims as shown with the 3/8" x 3-1/2" bolts.
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.
If it is difficult to insert a bolt into a hole, you can
enlarge it by passing a metal drill bit through it.

Merge the 2 lengths of Deck Support with the Union Plate using two 1/4" x 5/8" bolts. Locate the
center holes on the End Cross Members and attach this Support using the 3/8" x 2-½" hexagonal bolts.
Assemble the four (71-1/4 in.) Side Beams to create the two lengths that will become the sides of
your dock by inserting the Fusion Plates into the opening (A). Join them using the small 1/4" x 5/8"
bolts on the sides and the 3/8" x 1" bolts In the bottom edge.

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. 3
STRUCTURE

You will assemble the 3 decking panels upside down and then turn them over. This way, you
will not see the screw heads on the finished product. Note that the center panel will have 9
boards and the other two, 8. Place the Decking boards (a) on the frame, with their nice side
down, all leaning against the same side. Place the Decking Supports (b) 2.5" from the sides
and three, next to the Central Support (c), so as not to conflict with it.
As indicated on page 2, different types of decking can complete this dock.
Multinautic® offers pre-configured packages of cedar or polymer decking.
Those Decking Kits have their own installation guide. If you prefer to install
your own wood, here are the required elements for its construction and
the steps to follow:
> 150 deck screws #8 x 1 ¾”
> 18 flat head stainless steel screws #10 x 1 ¾’’
> 17 cedar planks: 5/4 in. (actually one-inch thick) x 6 in. x 8 ft (2.43 m)
1
Cut the boards into 48" lengths. To save on wood, if you are assembling more than one
dock section, you can split nine of these 48” boards into narrower lengths that will be used
as decking supports for panel assembly (choose the less nice ones).
Make cutouts in the 2 end boards to adjust them to the corners (6 mm or 1/4" approx.)
Before screwing these decking supports into the boards (6 screws per board), make sure
that the spaces between the boards are equal (+/- 3/8'' or 9 mm) and that the decking
supports are positioned parallel to each other. Pre-drill these supports at the 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 #10 x 1 ¾'' stainless steel
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 2 panels.

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 1/2" 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 reinforcements 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).
