The SamIdea Aviation Toolbox Catches are perfect for any industrial and scientific workholding needs. After I put it to the test, I found that they were surprisingly sturdy and kept my tools safe and secure. The catches provide a nice snug fit and are easy to install onto any toolbox or storage container. The only con is that they require a bit of effort to close, but it's a fair tradeoff for the added security. Overall, I highly recommend these toolbox catches for their quality and reliability.
