So it’s not a threaded pole but a pole with joints to connect it?

If it’s threaded it’s not an xpert, it would either be an old style xpole or cheap knockoff. If that’s the case the threads are probably bent or busted.

If it’s an xpole with joints to connect the pieces then you should see little x’s on the base of the pole and usually on the joints too. All joints have little notches that keep everything in place. If it’s not an xpole that may be missing and so the pole just keeps turning.

Here are 2 photos of X joints. The first is the older style with the small round bump that fit in the notch and second is the newer version with the larger oval bump.
