The First design component that enables the strength and flexibility of EZ Docks is the rubber couplers and nylon composite connection system. 2 tapered coulplers are used atop and beneath the dock - connected via a rod and nut. Each coupler can capture and disperse up to 4,000 lbs. of torsion (twisting) pressure each time the docks are impacted. When the docks encounter chop or inclement weather - shock energy is transferred from the docks to the couplers where it is absorbed and redistributed away from the system. This energy dispersal is essential to keeping the dock from experiencing wobbles or instability of any kind.
