Hager Hinge 175144 Full Mortise Spring Hinge 4x4 Steel Satin Brass

Product Description

The HAGER HINGE 175144 is a full mortise residential spring hinge designed for standard door installations requiring automatic self-closing action. Built from steel with a satin brass finish, this hinge measures 4 inches x 4 inches with a 1/4 inch radius corner profile. The spring mechanism provides consistent closing force without a separate door closer, making it a practical solution for interior residential doors. Licensed carpenters, door hardware installers, and general contractors typically install this hinge during new construction or door replacement work. It ships and is sold as an individual unit but must be ordered in multiples of 2.

The 175144 is suited for residential interior door applications where a self-closing hinge is required by code or by the specification, such as doors leading to attached garages, utility rooms, or other fire-rated or code-regulated openings. The full mortise design requires a routed mortise pocket in both the door edge and door frame, providing a flush, clean install typical of residential door hardware. Its steel construction and satin brass finish make it compatible with a broad range of interior door hardware finishes.

Installation Notes

Installation is performed by a licensed carpenter or door hardware installer using a chisel or router to cut mortise pockets in the door edge and door jamb. Ensure the door is fully removed or propped securely before mortising and hanging. The spring tension should be adjusted according to the manufacturer instructions to provide proper closing force without slamming. Local building codes may require self-closing hinges on specific door types such as garage-to-dwelling entries — verify applicable code requirements before installation.
