Description

The HAGER HINGE BB1816415EA is a full mortise, residential-weight ball bearing hinge finished in satin nickel. It measures 4 inches by 4 inches with a 5/8-inch radius corner on one leaf and a square corner on the other, making it a right-hand application hinge. Ball bearing construction reduces friction and supports consistent, smooth door swing over the life of the installation. This hinge is sold individually but must be ordered in multiples of two. It is appropriate for residential interior and light-duty exterior door applications installed by carpenters, general contractors, or skilled tradespeople.

This hinge is suited for residential door installations where a full mortise mount is required. The satin nickel finish integrates with a wide range of door hardware finishes common in residential construction and renovation. The right-hand, square-by-5/8-inch radius leaf configuration addresses door frames and slabs that require mismatched corner profiles between the door and the jamb leaf. Typical installation scenarios include pre-hung interior doors, hollow-core and solid-core slab replacements, and new residential construction.

Key Features

Right-hand orientation with square corner on one leaf and 5/8-inch radius corner on the other to match mixed door and frame profiles
Satin nickel finish for corrosion resistance and aesthetic compatibility with contemporary residential hardware

Compatibility

Designed as an OEM-style full mortise replacement hinge for residential-grade door assemblies requiring a 4-inch by 4-inch hinge with a right-hand square-by-5/8-inch radius leaf configuration.

Installation Notes

Installation requires mortise routing on both the door slab and the door jamb to achieve flush seating of each leaf. Power should be removed from any electric strike or access control hardware integrated with the door frame before beginning work. Use a sharp chisel or router with a mortise template to achieve clean, accurately sized pockets that prevent hinge rock or binding. Confirm door hand and swing direction before ordering, as this hinge is configured for right-hand application.
