I have an existing pool fence but one of the areas broke due to an accident. I kept looking for a replacement fence but a lot of the models had the stake type of bottom piece. This was the only one that continue the same diameter of the pole. It was a perfect fit with my existing fence. The new inserts were also a lot better and the new poles were a lot sturdier. My old fence was made of fiberglass where these new poles are a hard plastic.
