Surefire Cargo Hook Release Technology

Onboard's Surefire® Release Technology is a useful safety option for external load operators. An integrated electronic circuit is added inside the cargo hook, which provides about a half-second delay from when the electrical release button is pressed until the hook opens to help guard against inadvertent releases.

• Helps Prevent Inadvertent Releases — The half-second delay ensures that a purposeful engagement of the release button has been triggered, helping to prevent inadvertent external load releases caused by accidental contact with the button or momentary button mix up.
   
• Instant Release Authority Retained — Pilots can still use the manual release in an emergency if the hook must be opened immediately.
   
• Proven System Reliability — Solid-state circuit is environmentally sealed and contains multiple redundant components that have been rigorously qualified and tested per stringent FAA guidelines.

To make it easier to distinguish between hooks with Surefire and those without Surefire, we use a gold-colored solenoid housing case on the Surefire-enabled hooks, instead of our regular black anodizing finish.

Surefire is being continuously rolled out as an upgrade option on select cargo hooks. Please refer to our current chart of products offering a Surefire option here.
