Designed for Marine Environment - Constructed from Marine-Grade Powder-Coated Aluminum and tested for thousands of hours in salt spray to ensure reliability and stability in the harshest environments. 1.5" Ball Made of Marine-Specific, High-Strength Composite Material, which is more resistant to high salt water corrosion and less prone to deformation than rubber. Provides the same friction as rubber.
Longer Service Life - The ball and mounting plate are Molded in One Piece, rather than screwed together, for longer service life and to ensure the stability of the device. Cast in one piece of aluminum for strength and durability under the impact of waves. Relative to the 1" ball, the 1.5" ball is more reliable and stable in harsh marine environments.
