thanks for the advice. this is what I found https://www.mierproducts.com/Default.htm

basically it's a restaurant, and the manager does not want the staff to mess with the Point of Sale patch cords. I offered a box, which he liked. too bad there is not something already manufactured for this purpose: to lock the box and keep out un-authorized hands. (hmmmm...$$$)

thanks!
