Product Details

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) 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 mooving 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.

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.

    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.

        Q:Hello! We need a 180' permanent boardwalk over a pond and dune to a freshwater lake. The pond is 6-8" deep, sand bottom, and isolated - there is no water movement so no ice movement in winter. Would your dock be suitable for this year-round use?

        A:  Hello SueK, This kit comes with 6 ft long posts. So to install it in deeper water than 4 ft you would need to get longer posts and install braces on these as, with that height, is will be unstable. The ice movement doesn't occur in winter but in spring when it separates in blocks moving around when there is a storm that creates waves. I hope this helps. Thanks for your question.

          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
