Officially recognized as Zeiss' recommendation for using a tripod with the Victory T* FL 7x42, 8x42 and 10x42 binoculars, this also likely works with many other styles and series. It has a curved base upon which to place the binocular, with anti-slip surfaces right where the binocular's barrels would rest. The stalk which attaches to the tripod is deliberately offset, so that the pan/tilt arm of your tripod or monopod's head will be out of the way of your face.
