What is this product?

Hi,

I hope this question is in the proper section.

 

I recently got 2 of these "support", but I have no idea what they are used for or with what BOSE product.

The top part is a universal head, by that I mean it can be position in any direction and the other part seem to be a table braket, all that on a giant allen key.

The lengh is 12" for the shaft.

 

Any information will be greatly appreciated.

 

Good question but I have no idea. This is just a guess on my part but they look rather commercial/industrial in design so I'm wondering if perhaps they are from Bose's professional line of products? Sorry I can't be of more help.
