Hager 1764 4" x 4" Stainless Steel Spring Hinge | Square x 5/8" Radius
The Hager 1764 is a specialized residential weight spring hinge designed for automatic door closure in challenging "mixed-prep" environments. Featuring a unique hybrid corner configuration—one square leaf and one 5/8" radius leaf—this hinge is the professional solution for mounting new doors into existing frames without the need for additional mortising. Crafted from high-grade stainless steel, it is the premier choice for coastal properties and high-moisture areas.
Non-Ferrous Durability for Automatic Closing
Engineered to meet ANSI K51071F standards, the Hager 1764 utilizes stainless steel for both the hinge body and the internal spring components. This ensures the mechanism will not rust or seize, even when exposed to salt air or high humidity. The single acting spring provides a reliable self-closing force, making it ideal for garage-to-living-space entries or exterior patio doors where fire safety and energy efficiency are priorities.
Versatile Installation and Performance
To achieve the best closing performance, Hager recommends using all spring hinges or a combination of spring hinges and ball bearing hinges—avoid using plain bearing hinges in the same door set. Because screw hole patterns can vary significantly by manufacturer, please verify your existing door prep against the Hager template. If your pattern is unique, we can provide a special quote for a custom match.
