The square version of our SpinTopSign is sold separately, and designed to be affixed to your real estate post. It holds four 8x10 images (photo paper preferred) and contains a solar-panel lid and light interior, which turns on automatically at sundown. On a full charge, the light will stay lit for approximately four hours each night. The SpinTop spins manually, and contains four vertical wings that allow it to occasionally spin via wind-power.
The square SpinTop contains a bracket which is designed to sit on the horizontal arm of your real estate posts. 2 attached straps with a hook and loop closure wrap around the post to hold the SpinTop in place.
