Hager Hinge 175231215EA Steel Full Mortise Spring Hinge

Product Description

The HAGER HINGE 175231215EA is a full mortise residential spring hinge designed for standard door installations requiring controlled, automatic door return. The hinge measures 3-1/2 inches by 3-1/2 inches with a 5/8-inch radius corner and is constructed from steel with a satin nickel finish. The built-in spring mechanism provides automatic closing action without the need for a separate door closer. This hinge is sold as an individual unit but must be ordered in multiples of two to ensure matched pair installations. It is suited for interior residential doors where a clean, self-closing hinge is required by code or design preference.

This spring hinge is intended for residential interior door applications where automatic door return is needed. Full mortise design means it seats flush into routed mortises in both the door edge and the door frame, delivering a clean profile when installed. Typical installations include passage doors, utility room doors, and other interior applications requiring self-closing function. Installation is performed by a finish carpenter, general contractor, or qualified door hardware installer.

Installation Notes

Installation is typically performed by a finish carpenter or qualified door hardware installer using a mortise chisel or router with a hinge template. The spring tension is adjustable using the set pin included with the hinge — follow the manufacturer instructions for tension setting before final installation. Remove the door from its frame before routing mortises to ensure accurate placement. Verify local building codes for self-closing door requirements in fire-rated or accessibility applications.
