A wide range of latch sizes and actuation styles complement the versatile performance of this self-adjusting spring cam design. They satisfy a broad spectrum of applications where specific compression forces are not critical.

  • Ramped spring-quality pawl provides increasing level of compression as latch is rotated and enhances tension on latch in closed position
  • Serrated spring models provide greater friction for more vibration-resistant grip
  • User controls the amount of compression force
  • Spring steel cam design is more tolerant of rough handling as experienced with lift-off panels
  • Three-hole (round hole) mounting design accommodates rivet, stud, or weld mounting
