This listing is for 14 Anti theft tether devices. The high strength cable is 36 inches long with eye loop on the end , this gives you multiple mounting options.
The black box that houses the retractable cable is just over an 1 1/2 square and only 5/8 tall. It's very discrete.
We tried to break the cable on one ( not selling that one ) and none of us could get it to come off. A very strong little item.
The black base has 2 mounting holes so this can be screwed to the counter top or display.
We had one customer epoxy this to a shelf and it worked well.
See photos for further details.
