Designed for use with the Bubo, as well as a DSLR, the Alm Crossbar uses 1/4"-20 thumb screws to attach the camera of your choice. Once attached, the Crossbar can either be used to mount to a tripod or to mount offset accessories like lights and microphones. More specifically, when used with the Bubo, the flat surface of the thumb screws retains its ability to stand on its own and provide hands-free shooting.
The Crossbar is constructed out of billet aluminum and stainless steel. Plus, the machine work is even, smooth and done with skilled precision.
