Fits any of our tubular poles. This socket lowers the pole into the ground by 10 in. You can easily increase the height of your pole at a later time by adding one or more of several pole extenders. A benefit of this ground socket is that the pole can be removed for lawn maintenance. This socket is appropriate for lighter loads. If you intend to build a larger feeding station, we recommend the FP1GSX 15 in ground socket or the twister.
