(sometimes mislabeled as 620), typical datasheet specs are:
Understanding physical dimensions and weight ensures proper fitment and adequate galvanic protection lifespan. The "620" designation typically refers to a specific standardized weight or dimensional profile used by marine hardware manufacturers. Physical Dimensions
Features pre-cast slotted holes or an exposed galvanized steel strap with bolt holes. This allows for straightforward replacement during routine dry-docking.
