Sachtler Sandwich Touch-and-Go... safety lock?
 

I am about to order the Sachtler Touch-and-Go QR adapter, but I can't for the life of me find any pictures of or specs on the bottom of the unit.

Does it have an integrated safety lock as part of the latch, like the heads? I'm using this on a larger flat surface where a "pull-down" style safety would not be practical.

Anyone have pictures of the adapter's underside? I'm convinced that the only pic in existence is the birds eye product shot from sachtler. Also, how tall is it? About 1"?

Thanks,
