The Preferred Choice for Aircraft Latches and Latching Systems

Hartwell Corporation is a global leader in the design, development, and manufacture of latches and latching systems for the aerospace industry. With over 80 years of experience and expertise, Hartwell has earned the trust and recognition of major aircraft and engine manufacturers around the world. Hartwell’s latches and latching systems are installed on virtually every aircraft flying today, providing reliability, efficiency, and quality for various applications.  Latches and latching systems consist of several components, such as handles, hooks, pins, keepers, springs, hinges, rods, and struts. Depending on the type and function of the latch, they can have different features and benefits, such as:

  • Over-center locking: This feature ensures that the latch is fully engaged and locked when closed, preventing accidental opening or loosening due to vibration or thermal expansion.
  • Trigger safety lock: This feature prevents the latch from opening unintentionally by requiring a trigger release before the handle can be operated.
  • Free travel handle: This feature allows the handle to move freely without engaging or disengaging the latch until it reaches a certain position.
  • Pressure sealed: This feature prevents air leakage through the latch by using a seal or gasket between the handle and the housing.
  • Contoured: This feature matches the shape and curvature of the aircraft opening to provide a smooth and seamless appearance.
  • Adjustable: This feature allows the user to adjust the preload or tension of the latch to accommodate different sizes or tolerances of the openings.
