Seems to be just for a single pole situation if I understand this correctly, i found this in the lighting Dept as a free standing display seems to be a good price for 3 of them.
Was looking for a simple slider and do not have any experience with them yet as I have not had time to imstall.
Not sure how long these will be offered as they are a "Special Buy"
Any info you wish to share will be added to my posting.
Thanks!
