When the door is closed, the distance between the leaves is larger than the pin diameter, creating an offset to accommodate a gasket or trim. Longer than other hinges, piano hinges run the entire length of doors and lids for strength and durability.
304 stainless steel hinges are more corrosion resistant than low-carbon steel. They also have good chemical resistance.
