This is a part for the Skywalker 8' Trampoline sold at places like Walmart.

It replaces the plastic tops of the net poles (it protects you from landing on a sharp pole, and attaches the net to the poles).

The nut slot is slightly larger than the original nuts that come with the trampoline, but wrapping some tape around the nut makes it work just fine.

The dome is designed so that supports shouldn't be required. If you do use supports, set the X-Y distance to around 5mm or more.
