Quality Manufacturing

We proudly design, engineer, manufacture and assemble 100% of our cargo hooks in-house. Our internal engineers turn concepts on paper into the finest finished product in the industry.

Our CNC department uses state-of-the-art machining stations capable of unbelievable accuracy, consistency and repeatability. We use only the best aircraft grade materials ensuring the utmost in quality, strength and durability. All remote hooks are available with a rugged tubular steel guard also built in-house, and engineered to take the daily abuse of working in a hostile environment.

Quality Tested

All of our hooks are proof loaded to twice their rated working load limit to give you the peace of mind to know they can handle the load.

During testing, all of our cargo hooks have been pull-tested to five times their rated capacity, with no signs of fatigue or failure. You no longer have to use a hook rated at twice the capacity of your aircraft.
