Q:Will these work for attaching a ramp from a fixed dock to a floating dock with tide fluctuations?
by|Dec 5, 2022
3 Answers
Answer This Question

A:  Yes you can use these hinges to attach a gangway or ramp to a floating dock as long as the floating dock is free to rise and lower with the tide.

by|Dec 6, 2022

    A:  Hello Shelly, These hinges will have an opening angle up to 60 degrees. It's going to be up to you to figure out if it fits depending on your tide fluctuation level. You will install these hinges at both ends of the ramp which is going to be a semi-floating dock with one or 2 floats installed at the very end of that dock section. This dock section will not have any post to move freely to adjust to water fluctuation. The longer this semi-floating gangway will be between your fixed and your floating dock, the better its action will occur to maintain the whole dock system as leveled as possible. Thanks for asking!

    by|Dec 9, 2022

      A:  Depending on the fluctuations. 2-3 ft fluctuations will be fine. These are good and still doing their job after 10 years.

          A:  If you’re attaching a stationary dock to a stationary deck and they’re both going to be at the same levels you wouldn’t need these hinges.  

          by|May 18, 2022

            A:  You could. Not sure why you would buy hinge type product to attach to two stationary sections of dock/deck? These are typically used for attaching two floating parts to allow movement while floating . I suppose you could attach a fixed deck to floating ramp but only in cases where water rise or fall during seasons is minimal. The range of this hinge is limited. There are other products for that application. You attach the by using bolts thru the plate and thru dock or deck timber. Use hot galvanized parts with washers and lock washers. I don't recall diameter 1/2" or 5/8". Length depends on size of wood bolting through.

            by|May 18, 2022

              A:  You may want to go larger for a 24’. My floater is 12’ and these were perfect for me. You will need to buy the galvanized lag bolts to attach to dock.

              by|May 19, 2022

                A:  Why would you want to attach two stationary object together? These are intended for joining two movable or a fixed to a movable object together. For instance a floating dock to a ramp or a fixed deck to a ramp that may raise and lower to a floating dock. Not reaaly sure why you would want to use hinges to two fixed objects. We used these hinges to attach a 10'x8' floating dock to a 4'x10' access ramp that sits at a fixed point on the shore. You will need additional hardware to attach these hinges. 8 Bolts, 16 washers and 8 bolts per hinge. The length would depend on the material you are using. For instance we used 2" lumber so we bought 1/2 inch galvanized bolts that were 3 inches long.

                by|May 28, 2022

                  A:  Hello JoeB, These hinges are sturdy enough to handle floating dock movements. They will surely connect stationary docks. You need 1/2 in. x 3 in. carriage bolts and back plates or large washers to protect the wood. If you haven't built your dock yet, use the Corner Kit Model #19135 for structural strength. The inside corners will serve as back plates. Please contact our Customer Service to get personalized suggestions at 1-800-585-1237 or by email : info@multinautic.com

                      Strong and Easy
                      I needed to rebuild the shoddily-built connection between the dock ramp and landing. This product served the purpose perfectly. It feels very heavy-duty, attached easily with lag bolts, and the sturdy cotter pins allow for secure attachment but straightforward disattachment. The connector provides about 45 degrees of movement vertically, but not much horizontally, when installed as shown.

                      No worries with these dock hinges
                      Got these to connect my main dock to the dock ramp, these things definitely leave me worry free. The dock sure as heck will not move with these hinges! They are very sturdy and weigh a ton. Another great product from this company (also got one of their floating dock kits and dock solar light kits which also left me 100% satisfied with my purchases). Highly recommend these, don't try to improvise with makeshift hinges, get the good one right off the bat, well worth it in price and security.

                        These hinges are bullet proof. I installed 2 sets on a floating dock and they work just as I envisioned. In fact, a friend looked tat them and said that is what he should have purchased instead of barn door hinges - which he has replaced a few times.

                        Hello Mark, Thanks for this nice review and the Five Stars! It helps customers to make the right choices. For them, let me add that these hinges can be installed in combination with the Inside Corners Dock Kit #19135. For dock posts or anchor chain installation, the Leg Holder or Chain Retainer Dock Kit #19111 is perfect for a complete dock section that can be part of a sturdy floating or stationary dock layout. multionline
