Four bar window hinges and tracks are engineered for precise control and stability when opening and closing casement or awning windows. Often used in both residential and commercial settings, these stainless steel hinges enable the window sash to project outward, preventing interference between the sash and frame while delivering smooth operation and lasting durability. Four bar hinges are non-handed, so they fit either left- or right-opening windows, making them an adaptable solution for a wide range of window designs.

Key Features and Specifications

  • Available in standard and heavy-duty versions for projects ranging from light residential windows (up to 40 lbs.) to heavy commercial applications (up to 200 lbs.).
  • Corrosion-resistant stainless steel construction ensures long service life, even in harsh conditions.
  • Integrated stops on many models help control the opening angle, improving safety and usability.
  • Friction adjustment screw in the sliding shoe lets users fine-tune sash movement to match preferences and window requirements.
  • Compatible with a variety of window operators, including "Dyad" (two-link) mechanisms.
  • Non-handed designs simplify ordering and installation for both left- and right-hinged windows.

Typical Applications and Replacement Tips

Four bar hinges and tracks are commonly found on casement windows, awning windows, and projected vents where controlled outward movement is required. They are an ideal replacement part for windows from leading manufacturers such as AmesburyTruth, including their Anderberg 201 and 301 series. Ensure you select the correct track length and duty rating for your window's size and weight. For example, a standard 8-inch track fits many smaller residential windows, while a 20-inch heavy-duty track supports larger, heavier sashes.

Installation generally requires only basic tools. Most four bar hinges install with #10 pan head stainless steel screws (typically not included). Make sure to measure your existing hinge and track dimensions carefully before ordering. If your application calls for a hinge without a stop for maximum opening range, options such as the 10-inch track with no stop are available. For egress windows or special project needs, consider a 12-1/4-inch egress hinge for safe and code-compliant operation.
