Is my track light a Juno Track Lighting or Juno Compatible?
The Juno Lighting Track / JT system is known as 2 wire-wide single circuit system. If you look at the track itself, it should have one strip of wire on each side.
On the back of the track light junction plate, there should have one clip terminals on each side. The maximum distance between two strips from side to side should be just shy of 1" or 15/16". Please see the photo on the left.
