The aerial hoop (also known as the lyra, aerial ring or cerceau) is a circular steel apparatus (resembling a hula hoop) suspended from the ceiling, on which circus artists may perform aerial acrobatics. The hoop sometimes has a hand loop and a bar across the top. It can be used static, spinning, or swinging.
Tabs are the connection points where the aerial hoop attaches to the rigging. Most aerial hoops connect at either one point (single tab configuration) or two points (double tab configuration).
