Ok, so suspensions aren't my thing, but I've owned this one for a long time, and I figured it deserved to be posted. An UG marked J-D suspension in blue. It has the top hanger, but I can not say if it's original to this piece. It has a clamped in hook on the bottom side. Very cool style of attachment. Marked as shown. These types are amazingly heavy! A full set of these must have been a real joy to put up onto a pole or tower.
