Hinge Leaves
Longer than other hinges, piano hinges run the entire length of doors and lids for strength and durability. These hinges have a standard clearance—when they are closed, the distance between the leaves is about the same as the pin diameter.
Titanium hinges are more corrosion resistant than 316 stainless steel. They also have good acid resistance.
Note: Prices are 15% to 20% lower when you buy 10 or more hinges of the same size.
