Early versions of UNISEG Product’s UNISEG Container used an over center latch commonly used to secure box and container lids. These over center latches were being frequently damaged when uncoupled from their hook, due to the latch and its handle not being secured. The unsecured latch and handle also represented a safety risk by potentially “gouging” people.
As a result of these problems UNISEG Products designed and developed the Snap-Flat latch where the latch and handle ‘Snap’ back to the FLAT POSITION, when the latch is un-coupled from the hook.
The Snap-Flat delivers two primary benefits. The first is to do with the latch and handle remaining in the flat position when de-coupled, eliminating the risk of injury and reducing the potential for the latch to be damaged from accidental impact.
The second important benefit of the Snap-Flat design is that it prevents the latch from disengaging from the hook, even if the over centre latch is NOT secured into the over-center position.
Best latches I have found
The Snap-Flat latch is far more solid and better engineered that the standard ones. On its own, that would be enough for Lazy Lizard to adopt them. But they have a very clever spring loaded design that keeps the latch under tension. This greatly reduces the chance of it rattling loose and will even keep it in position if it hasn't been tighten correctly. While the latch is undone, it sits flat, so it can't accidentally catch something or rattle around loosely.
I usually have one of the standard hold down clips let go each trip, I travel rough out back tracks and have a bad habit of driving fast, these new snap flat latches are the ducks nuts, they don't let go, I have recommended to my other prospecting mates
