Can a tailgate latch with one moving part qualify as a pinnacle product? Absolutely. In fact, that’s exactly why it does.
I’m not sure when the “Antiluce” (get it?) latch was invented—Google suffered a rare fail in not finding me something like an Antiluce Appreciation Society with monthly meetings at the Queen’s Head in Tunbridge Wells. I know they were on Series II Land Rovers because I’ve seen them. Photos of JUE 477, the very first production Land Rover, seem to show a type of Antiluce latch, perhaps refined as production progressed. For all I know it could have been invented decades before that. A small British company named Burrafirm, later purchased by Albert Jagger Limited, seems to have held the patent for quite some time.
The Antiluce is so simple that it would take the proverbial one thousand words to describe it, so if you’re not familiar with it look at the photos and it will be clear. It’s essentially a toggle latch—flip it horizontal to close the tailgate and the hole in the hasp fits over it. Then flip it vertical, push in on the tailgate to snug it against its weather strip, and the stepped opening in the Antiluce automatically takes up the slack and ensures a rattle-free fit. With new weatherstrip the latch might only drop down to the first or second step, but as the weatherstrip beds in or wears, the latch simply drops down a step at a time to maintain consistent tension. Brilliant. Its natural tendency is to obey gravity, so if the tailgate flexes over rough roads the pin will only snug itself, not loosen or come unfastened.
The drop-down tailgate on my FJ40 closes with over-center draw latches, which are bulkier, heavier, fiddlier, and no better. If I ever do a complete restoration on the Land Cruiser I plan to convert it to Antiluce latches. They’re available from numerous sources including all the major Land Rover stores, and could easily be adapted to other uses on custom trailer compartments or cabinetry. The threaded shaft can be had in several lengths, and there are weld-on versions too. At around $30, it’s possibly the cheapest pinnacle product on earth.
