Boat-specific tube and sling lengths provide a custom fit for each boat, enabling a balanced handle load and easy maneuvering. All joint fittings are through-bolted and designed for increased torque stability. Strong, 3" non-stretch, polyester sling provides wrap-around boat support. Adjustable, flexible V-fitting on tongue tube provides boat support forward of the sling and prevents boat and aluminum contact. Eyelets on sling and handle fittings facilitate securing boat to dolly in storage, on trailers or in racks. Tie-down with the handle fitting eyelet helps prevent slippage on steep ramps. Easy dolly breakdown using the snap buttons on wheel shaft and tongue tube, as well as wing nuts on axle tube cross fitting. Pneumatic, non-corrosive, 16" x 4" wheels can be secured on wheel shaft with provided screws for added security. For soft sand conditions, tire pressure can be reduced to increase tire footprint. Proudly made in the USA.
