Then you need some sort of tripod quick release-lever gadget to make that handy to do. These are sold at camera shops if your tripod did not come with one.
I'd also mention when locating the fixture, put it at the point of ballance when the box is open and a panel and the boxes contents are fitted to it. This will be further towards the back then at first you'd think. That will help keep the box level in use. Enjoy!
Agreed, particularly about the "point of balance", rather than exact center.
If this sounds hard, it's actually quite easy if you have a drill. And the quick release plate (assuming you have a tripod that uses one) is cheap on eBay.
