Hager Hinge BB1817415EA Full Mortise Ball Bearing Hinge

Product Description

The HAGER HINGE BB1817415EA is a full mortise, residential weight ball bearing hinge designed for interior and light-duty door applications. It features a left-hand square by 5/8-inch radius corner configuration and measures 4 inches by 4 inches, making it a standard fit for residential door frames. The satin nickel finish provides a clean, neutral appearance suited to a wide range of door and frame finishes. Ball bearing construction reduces friction and wear over repeated operation cycles. This hinge is installed by carpenters, finish contractors, and general tradespeople working on door hardware rough-in or finish trim.

This hinge is suited for residential full mortise applications where the hinge leaf is recessed flush into both the door edge and the door frame. The left-hand square by 5/8-inch radius profile meets common residential door prep standards. Typical install scenarios include new construction interior doors and door replacement projects. The unit ships and must be ordered in multiples of two, consistent with standard door hinge pairing practice.
