Extra-Clearance Piano Hinges
Between Hinge
Leaves
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.

Extra-Wide Mortise-Mount Hinges with Holes
Open doors past their frame to make extra room for people and large items, such as carts, furniture, and wheelchairs, to pass through. Because these setback hinges create wider doorways, they help reduce the risk of bumping and damaging the door and frame. The leaves on these hinges fit into cutouts (mortises), so they mount flush with the surface of the frame and door. All of these hinges are ADA compliant when correctly installed.
