Hager Hinge 175443 Full Mortise Spring Hinge 4x4 Bright Brass

Product Description

The HAGER HINGE 175443 is a full mortise residential spring hinge designed for standard door installations where automatic self-closing action is required. Built from steel with a Bright Brass finish, this hinge measures 4 inches x 4 inches with a 5/8 inches radius corner profile. The spring mechanism provides controlled door return without a separate door closer, making it a practical choice for interior residential applications. Licensed carpenters, finish installers, and general contractors typically specify this hinge for passage doors in residential builds and light commercial retrofit projects where code or design requires self-closing doors.

This hinge is suited for residential interior doors requiring self-closing function. The full mortise design requires a routed pocket in both the door edge and frame, making it compatible with standard pre-hung door setups. The 4 inches x 4 inches leaf size accommodates typical interior door thicknesses and weights. The Bright Brass finish suits traditional and transitional interior hardware packages. Note that this item must be ordered in multiples of 2.

Installation Notes

Installation is typically performed by a finish carpenter or licensed door hardware installer. A mortise must be routed into both the door edge and the door frame jamb to seat the hinge leaves flush before fastening. Ensure the door is fully supported and all fasteners are fully driven before testing spring tension. Follow local building codes for self-closing door requirements, particularly in fire-rated corridor or dwelling-unit applications.
