About This Product

The QP-427 Stationary Aluminum Dock Kit is a great lightweight, easy to assemble and install, 4 ft. W x 8 ft. L dock. The all-aluminum structure with stainless steel assembly hardware and hot dip galvanized steel posts and base plates, makes this dock totally rust free and easy to maintain. It's ideal for shallow waters up to 4 ft. deep. It includes all the necessary hardware to join 2 docks either end to end, side-by-side or even in an «L» shape. Although this dock is ultralight, it can handles up to 800 lbs. The kit comes with two (2) 1-11/16 in. o.d. hot dip galvanized steel posts. Multinautic's custom aluminum extrusion has a unique "UniTrack" system on each side, enabling to insert special mooring cleats (not included) and other accessories without the need to drill or screw into the wood decking allowing you to move them easily to fit your changing needs. This kit is affordable and easy to build whether you're a handyman or not! The result is a nice and long lasting dock.

  • In the box: 2 alum. sides (96 in.), 1 alum. central support (48 in.), 2 alum. end pieces (48 in.), 2 galv. steel leg posts (6 ft.), 2 galv. steel base plates (6 x 6 in.), 2 PVC post caps, 2 junction plates, 1 corner adapt., 1 parallel adapt., S.S. hardware
  • As all aluminum stationary docks must be removed from water for wintertime, this structure has been designed to be light without loosing sturdiness in the process
  • Can be assembled by one person and installed with ease by only two people
  • We recommend cedar for decking as it's lightweight, soft and it's renowned for its naturally occurring resistance to moisture, decay, and insect damage
  • The great design allows to assemble the decking boards as a panel and then flip it over to secure it in place with a couple of screws. Download the instruction guide from this web page for assembly details
  • Even with their lightweight, some people are concerned about moving the docks. Multinautic Wheel Kit #22005 is suggested when encountering seasonal water fluctuations and will be a great help for the installation or their removal for winter

Q:CAN I USE 3/4 PVC BOARDS FOR THE DECKING
by|Aug 6, 2023
2 Answers
Answer This Question

A:  I used composite decking supported by (2) 2x4 cedar runners equally spaced between the aluminum side rails. The only reason for the composite decking was I couldn’t buy cedar decking due to a shortage at the time. The composite decking worked fine with the exception that it is extremely heavy when you need to move the dock.

by|Aug 6, 2023

    A:  Hello Annmarie, PVC decking may be too flimsy for use on the dock, and might require additional supports/stringers underneath. The manufacturer or seller of the PVC may be able to help you in this regard (as we do not manufacture PVC we would not have this info). Also, the decking should be flush with the rails so as not to run your toe into the frame. 1'' thick decking is recommended. You can phone 800-585-1237 or email Info@MultiNautic.Com if you have more questions or need any help.

      Q:Can this dock be used for a floating dock with barrels
      by|Jun 21, 2023
      3 Answers
      Answer This Question

      A:  According to the Multinautic on-line catalogue, that model dock is not recommended to use as a floating dock. Mine is on wheels.

      by|Jun 26, 2023

        A:  It can be used as a floating dock with Multinautic floats. I am not sure about barrels, but guess those might work as long as you can properly attach them.

        by|Jun 26, 2023

          A:  Hello Daleneb, This dock is not design to be floating. Structure, connectors, end pieces, bottom edge...These are not meant for floating purposes. Look for item 21519 instead. Thanks for asking!

            Q:Is it possible to swap the poles out for 10? poles to be used in 6 ft of water?
            by|Jun 1, 2023
            1 Answer
            Answer This Question

            A:  Hello Will, The poles that come with the dock are 6 feet. They are stable, and at this length (2 feet above the dock, and about 4 feet below the dock) it is relatively easy to remove them and their base plates in Fall - before the Winter freeze. 10-foot poles would be less stable, and the base plates much harder to access.. Floating docks are a better option in deep water.

              Q:we have an existing steel frame roll in dock which we love but would like to add a section to shore end a platform on the water end. Can the multinautic system be joined to a steel frame?
              by|May 26, 2023
              2 Answers
              Answer This Question

              A:  Hello Gacar, Please contact our customer service by email or over the phone as this question needs precisions. Do you want to be able to roll-in our dock if it's attached to yours? How wide is your steel frame? Have you read the Instruction/Assembly guide on this page? Please reach out to us 1-800-585-1237 or info@multinautic.com as this platform is not designed to chat. We would love to help you but we need more information to do so. Thank you for your understanding.

              by|May 26, 2023

                A:  Not knowing what your steel frame dimensions are or what it looks like, or what configuration you want, is hard to answer that question. In the worst case, I would say you will need to have custome attachment brackets made.

                  Multinautic Dock
                  I purchased this product and installation was easier then expected. The one hiccup is that the pre-cut cedar decking kit does not fit in and each board still needed to be cut. All the videos showed the boards fitting perfectly, with no cutting. My goal was to assemble the 4 units myself and have it installed. Unfortunately I had to have a contractor do the cutting and installation of the boards as I did not have the required power saw. The installation into the water went relatively smooth, and I would recommend this product.

                  Please call me at 800-585-1237, or email me at Info@MultiNautic.Com. You were not to have cut any of the boards. We will rectify the situation to your satisfaction.

                    As advertised. Sturdy dock!
                    This kit was relatively easy to assemble. Make sure to cut your boards to the length noted in the directions. No longer! I am very pleased w the structural strength. I did utilize some augers for the poles that were in the river. Highly recommended and affective. This kit exceeded my expectations.

                    Hello Captain North,

                    Thank you for the great review, and also for pointing out that the length of the boards must be cut as specified in the assembly guide. This will preclude other people who read your review from having installation issues. We can always be contacted through the phone number and email address on our multinautic website should you ever need any assistance regarding parts or technical help. multionline

                      Great kit, easy to work with
                      I bought two of these kits and was able to put them together by myself with ease. Because I bought two sections I was able to use 4 poles to assemble the frames and keep them elevated while I cut and put together the cedar planks.

                      Thank you Marty for this nice comment and for the tip about assembling the decking while the dock is on 4 posts, more or less to a table height. multionline
                        Perfect for my application
                        These dock frames are easy to assemble and preparing the wood required is also easy. Due to the lake icing over the dock assembly must be removed every year, the wood is a little heavy to move alone but the actual dock frames are very easy and I am 71 years old.

                        Thank you for this nice review that confirms that our QP-427 Dock is a light dock easy to assemble. Note that you can lighten even more the wood panels by modifying them into smaller sections to ease handling. Just add a few screws at the last step of installation to secure all panels on dock sides. Thanks again for the 5 stars! multionline

                        Great dock of kayaking.
                        I purchased 2 units for kayaking. I bolted them together in a tee-configuration and added wheels with height adjustment to the wide end (water end) of the dock. The units arrived in perfect condition with all parts present. The assembly process was easy, all holes aligned property, I did have to drill four holes in order to create the tee-configuration. The decking is not included with the kits and the manufacturer does not recommend pressure treated lumber only cedar decking. At the time cedar decking was not available if your life depended on it so i chose Trex Enhanced Naturals Rocky Harbor Sq. Edge (capped composite) which so far has worked fine other than its heavier than cedar would have been. I would purchase again if ever needed.

                        Oh so easy!
                        Purchased 4 units, assembled 4 units, put 4 units in the canal... in a weekend by myself! Imagine if you had help! The door is sturdy, withstood ETA storm surge 2 feet under water and still solid as a rock. The ease of assembly was great. Only complaint is the Home Depot doesn’t carry all the accessories like the dock bench or make the readily available. But, having Sid that, it is a great product.

                          Extremely durable product with ease of assembly. It was just me, but in three days of on and off attention I completed a 4 - 4x8 section dock in an L shape utilizing the parts provided. It looks great! It already met the elements of Hurricane ETA and the storm surge put it a foot and a half of water! She didn’t budge! If I could load photos I would. Now for the accessories of Home Depot would only carry a variety of their products.

                          Excellent product and even better customer service
                          The dock went together easily with no issues what so ever. We have been enjoying our new dock for 2 seasons and couldn’t be happier. I called Multinautic’s customer service to ask about connecting to an older aluminum post dock to our new Multinautic dock and before I knew it, the agent was sending me bolts I had lost ....free of charge. I’m now a customer for life!!!! Thank you

                            My husband are both 65 years old. We are able to install & remove this dock with just the two of us. We used PVC boards for the deck with cedar runners under the PVC boards & it turned out great. Easy to assemble.
