Built from steel with a decorative oil rubbed bronze finish, this round-corner hinge features a 1/4-inch corner radius that suits standard door prep cuts on interior passage doors.

This hinge is intended for interior residential doors where a 3-inch round-corner hinge is specified. The 1/4-inch radius corner profile fits routed door-prep mortises cut for standard round-corner templates. The oil rubbed bronze finish coordinates with matching door hardware in residential remodel and new construction projects. Minimum purchase quantity is 3 units per order.

Installation Notes

Installation is typically performed by finish carpenters or residential contractors as part of door hanging. The mortise should be routed or chiseled to match the 3-inch by 1/4-inch radius leaf profile before fastening. Ensure the door is properly supported before driving screws to prevent leaf misalignment. Follow local building codes for required hinge quantity per door based on door height and weight.
