A hold-down assembly for retaining a portable electronic unit within an avionics equipment mounting tray includes a shaft, a locking collar, and an actuator knob. The shaft is coupled to pivot with the mounting tray. The locking collar slides along the shaft to engage the portable electronic unit. The actuator knob includes a knob body, a ratchet plate having detent holes within the knob body, a ball bearing, and a compression spring within the knob body. As the actuator knob is rotated to move along the shaft, the knob body and the ball bearing rotate with respect to the ratchet plate, and the ball bearing is forced against a spring bias of the compression spring as the ball bearing travels between adjacent detent holes.
