Hager BB1543 4" x 4" Non-Ferrous Hinge | Square x 5/8" Radius Corner
The Hager BB1543 is a specialized residential plain bearing hinge designed for "mixed-prep" applications where a standard hinge won't fit. Featuring one square corner leaf and one 5/8" radius rounded leaf, this hinge is the professional solution for hanging new, factory-prepped doors into existing square-mortised frames. Crafted from high-quality non-ferrous materials, the BB1543 is inherently rust-proof, making it the premier choice for coastal homes, luxury bathrooms, and laundry rooms.
Specialized Hybrid Design and Construction
The Hager BB1543 eliminates the need for time-consuming field mortising by providing a dual-corner configuration that adapts to your existing door and frame. Available in solid brass or stainless steel, this hinge is strictly non-ferrous, ensuring it will not pit, rust, or corrode when exposed to moisture or salt air. The removable pin and right-hand assembly allow for a precise, easy installation on standard residential door swings.
High-Quality Residential Engineering
With a .085 metal gauge, this hinge provides reliable support for standard interior and exterior residential doors. To ensure a lifetime of silent, friction-free operation, Hager recommends lubricating the hinges with lithium grease during or after installation, as residential units are provided unlubricated. This allows for a smooth, high-end feel that protects both the door and the frame from unnecessary wear.
