Product Use: Step-by-Step Installation

Attaching a floating dock doesn’t have to be complicated. With the right hinge kit, the process is straightforward and secure. Here’s how to use the hinge kit effectively:

Step 1: Prepare the Stationary Dock

Choose the side or end of the dock where your floating dock will connect. Position the male hinge plate on the edge and fasten it using heavy-duty bolts. Pre-drilled holes make alignment quick and simple.

Step 2: Prepare the Floating Dock

Install the female hinge plate on the floating dock, aligning it with the stationary dock’s hinge plate. Proper alignment ensures smooth connection and flexibility.

Step 3: Connect with the Hinge Pin

Bring the two docks together and insert the hinge pin through both plates. Lock it securely with the provided safety pin or cotter mechanism. This step creates a firm yet flexible connection.

Step 4: Add Extra Stability (Optional)

For waterfronts with strong waves or fluctuating water levels, attach chains, guide poles, or gangways. These accessories prevent drifting and improve overall safety.

Step 5: Test the Dock Connection

Walk across the dock connection point to test strength and movement. The floating dock should move up and down freely with the water while staying securely attached to the stationary dock.

Maintenance & Care

To extend the lifespan of your dock system and maintain safety, follow these simple care tips:

  • Inspect regularly – Check hinge bolts and pins to ensure they remain tight.

  • Replace corroded parts – Swap out rusted hardware immediately to avoid structural failure.

  • Clean hinge areas – Prevent debris buildup that may interfere with movement.

  • Adjust accessories – Chains or poles may need repositioning if water levels shift dramatically.

Routine maintenance will keep your dock system secure and reliable for years to come.
